Description

SYSTEME ET PROCEDE DE LOCALISATION D'UN TERMINAL MOBILE ET D'OBTENTION D'INFORMATIONS LIEES A CETTE SYSTEM AND METHOD FOR LOCATING A MOBILE TERMINAL AND OBTAINING INFORMATION RELATED TO THE SAME
LOCALISATIONLOCATION
L ' invention concerne un système et un procédé de localisation dans la zone de couverture d'une borne radio, d'un terminal mobile relié à un réseau de télécommunicatio . Le domaine de 1 ' invention est celui de la localisation d'un terminal mobile relié à un réseau de télécommunication, tel qu'un radiotéléphone ou un téléphone mobile, et de l'obtention d'informations liées à cette localisation. Parmi les systèmes actuels de localisation d'un téléphone mobile, on peut citer le GSM (Global System for Mobile) par triangulation et le GPS (GeoPositioning System) .The invention relates to a system and a method for locating in the coverage area of a radio terminal, of a mobile terminal connected to a telecommunication network. The field of the invention is that of locating a mobile terminal connected to a telecommunications network, such as a radiotelephone or a mobile telephone, and obtaining information related to this location. Among the current mobile phone location systems, we can mention the GSM (Global System for Mobile) by triangulation and the GPS (GeoPositioning System).
On rappelle que le GSM est basé sur un réseau de stations de base (Base Station Subsystem) installées par 1 ' opérateur du réseau et ayant en particulier pour fonction de localiser le téléphone mobile plus généralement appelé terminal mobile, se trouvant dans leur zone de couverture radio : en mode veille, le terminal mobile écoute continûment son environnement radio et quand le terminal mobile détecte un changement de zone de localisation (c'est-à-dire un changement de station de base) , il déclenche une procédure de mise à jour de localisation afin d'informer le réseau de ce changement. Les informations de localisation obtenues sont enregistrées également à la mise sous tension du terminal mobile, lors de son arrêt, au moment des établissements de communication et lors des changements de cellules ("handover") en cours de communication. Il existe enfin une mise à jour périodique par le réseau, des informations de localisation, si le réseau n'a pas reçu d'informations de localisation après une durée paramétrable .It is recalled that the GSM is based on a network of base stations (Base Station Subsystem) installed by the network operator and having in particular the function of locating the mobile telephone more generally called mobile terminal, being in their coverage area radio: in standby mode, the mobile terminal listens continuously to its radio environment and when the mobile terminal detects a change in location area (i.e. a change in base station), it initiates an update procedure to inform the network of this change. The location information obtained is also saved when the power is turned on. mobile terminal, when it is stopped, at the time of communication establishments and during cell changes ("handover") during communication. Finally, there is a periodic update by the network, of location information, if the network has not received location information after a configurable period.
Le GSM par triangulation présente des inconvénients . II ne peut offrir qu'une précision de localisation réduite variant d'une centaine de mètres à plusieurs kilomètres notamment en zone rurale, et pouvant présenter en outre certaines distorsions liées à l'environnement (immeuble, relief, ...) . Par ailleurs, l'installation de nouvelles stations de base permettant d'améliorer la couverture du réseau GSM en diminuant ces distorsions, relève de l'opérateur du réseau et non de l'utilisateur du terminal mobile ou des entités liées à la zone couverte, désireuses de fournir une information plus précise ou de plus grande qualité.GSM by triangulation has drawbacks. It can only offer reduced localization accuracy varying from a hundred meters to several kilometers, particularly in rural areas, and which may also present certain distortions linked to the environment (building, relief, etc.). Furthermore, the installation of new base stations making it possible to improve the coverage of the GSM network by reducing these distortions is the responsibility of the network operator and not of the user of the mobile terminal or of the entities linked to the area covered, wishing to provide more accurate or higher quality information.
Enfin, la localisation est indépendante de la volonté de l'utilisateur du terminal mobile dans la mesure où le système fonctionne même lorsque celui-ci est en veille : l'utilisateur est en quelque sorte pisté.Finally, the location is independent of the will of the user of the mobile terminal insofar as the system works even when it is in standby: the user is in some way tracked.
Le futur système UMTS (Universal Mobile Télécommunications System) devrait permettre d'obtenir une meilleure précision de localisation, sans toutefois apporter de solution aux autres problèmes . Le GPS fournit une meilleure précision en particulier en zone rurale mais présente des inconvénients en zone urbaine lorsque celle-ci comporte par exemple des passages souterrains ou à 1 ' intérieur d'immeubles : en effet, le signal GPS n'est pas perçu au travers d'un mur. De plus ce système ainsi que le système GSM ne permet pas de localisation spatiale à trois dimensions. Enfin, le système GPS est cher.The future Universal Mobile Telecommunications System (UMTS) should make it possible to obtain better location accuracy, without however providing a solution to the other problems. GPS provides better accuracy, particularly in rural areas, but has disadvantages in urban areas when it includes, for example, underground passages or inside buildings: in fact, the GPS signal is not perceived through of a wall. In addition, this system as well as the GSM system does not allow three-dimensional spatial location. Finally, the GPS system is expensive.
Les terminaux mobiles basés sur des systèmes de localisation couplant les systèmes GPS et GSM, sont chers, encombrants, lourds et consomment beaucoup d' énergie.Mobile terminals based on location systems coupling GPS and GSM systems are expensive, bulky, heavy and consume a lot of energy.
Le but de la présente invention est donc de résoudre le problème de la localisation à trois dimensions d'un terminal mobile, avec une meilleure précision que celle obtenue par les systèmes actuels et en permettant à l'utilisateur de pouvoir éventuellement intervenir sur la couverture du réseau.The purpose of the present invention is therefore to solve the problem of three-dimensional localization of a mobile terminal, with better precision than that obtained by current systems and by allowing the user to be able to possibly intervene on the coverage of the network.
L ' invention est basée sur une technologie bas coût de type Bluetooth. On rappelle que le consortium Bluetooth (BT) qui regroupe des industriels, est chargé de définir des spécifications pour connecter entre eux par voie radio des équipements séparés d'une distance inférieure à 100 m. Cette portée dépend en fait de la puissance de l'émetteur qui peut aller aujourd'hui de 1 milliwatt à 100 illiwatts et de la sensibilité du récepteur recevant le signal émis . Généralement une puissance de 1 milliwatt correspond à une distance de 10 mètres et 100 milliwatts à une distance de 100 mètres. Des émetteurs fournissant d'autres puissances sont envisageables .The invention is based on a low cost Bluetooth type technology. It will be recalled that the Bluetooth consortium (BT), which brings together manufacturers, is responsible for defining specifications for connecting equipment separated by a distance of less than 100 m by radio. This range depends in fact on the power of the transmitter which can range today from 1 milliwatt to 100 illiwatts and on the sensitivity of the receiver receiving the transmitted signal. Generally a power of 1 milliwatt corresponds to a distance of 10 meters and 100 milliwatts to a distance of 100 meters. Of transmitters providing other powers are possible.
Ces spécifications Bluetooth permettent de réaliser des connexions synchrones (pour la transmission de la voix) ou asynchrones (pour la transmission de données) dans la bande de fréquences des 2 , 4 GHz , remplaçant avantageusement les connexions filaires ou infrarouges existantes .These Bluetooth specifications allow synchronous (for voice transmission) or asynchronous (for data transmission) connections to be made in the 2.4 GHz frequency band, advantageously replacing existing wired or infrared connections.
De nombreux terminaux mobiles sont ou seront prochainement équipés de puces ou circuits intégrés BT, notamment les radiotéléphones et/ou les téléphones mobiles, pour faciliter les connexions avec des périphériques, voire avec un réseau d'accès.Many mobile terminals are or will soon be equipped with LV integrated circuits or chips, in particular radiotelephones and / or mobile phones, to facilitate connections with peripherals, or even with an access network.
Plus précisément, l'invention est basée sur l'utilisation de bornes de localisation communiquant par voie radio selon un protocole de radiocommunication de type BT, avec des terminaux mobiles se trouvant près de ces bornes ; ces bornes ne sont reliées à aucun réseau d'accès et agissent comme des balises géographiques en émettant une information assimilable à un code barre radio unique.More specifically, the invention is based on the use of location terminals communicating by radio according to a BT type radiocommunication protocol, with mobile terminals located near these terminals; these terminals are not connected to any access network and act as geographic beacons by transmitting information comparable to a unique radio bar code.
Le terminal mobile ayant récupéré ce code d'identification unique, le fournit à un serveur qui, en retour lui communique les informations liées à la borne, notamment à la localisation géographique de la borne .The mobile terminal having recovered this unique identification code, supplies it to a server which, in return communicates to it the information linked to the terminal, in particular the geographic location of the terminal.
Cependant, le système selon l'invention prévoit également d'envoyer séparément le code d'identification BT et un code de l'information désirée, ce qui implique qu'à un seul code d'identification plusieurs types d'informations sont disponibles. C'est donc la conjugaison du code d'identification unique et du code supplémentaire relatif à un choix de type d'informations qui permet à l'utilisateur d'atteindre, quand elle existe, l'information correspondant à son pôle d'intérêt. Ainsi, l'utilisateur en fournissant l'identifiant du type d'information souhaité s'évite la lecture d'une information qui ne correspondrait pas à sa recherche ou son pôle d'intérêt.However, the system according to the invention also provides for separately sending the identification code BT and a code of the desired information, which implies that with a single identification code several types of information are available. So this is the conjugation of the unique identification code and the additional code relating to a choice of type of information which allows the user to reach, when it exists, the information corresponding to his pole of interest. Thus, the user by providing the identifier of the type of information desired avoids reading information that does not correspond to his research or his area of interest.

The mobile terminal can be a radiotelephone or a mobile telephone or a personal organizer or a personal computer.
L'invention concerne également un procédé d'obtention d'informations liées à la localisation dans la zone de couverture d'une borne radio d'un terminal mobile relié à un réseau de télécommunication relié à au moins un serveur, caractérisé en ce que la borne est indépendante dudit réseau de télécommunication et en ce qu'il comprend les étapes : a- d'envoi par ladite borne d'un code d'identification unique à destination dudit terminal mobile, selon un protocole de radiocommunication courte distance, b- d'enregistrement par le terminal mobile dudit code d'identification unique en vue d'une consultation ultérieure du serveur, c- de communication par le terminal mobile dudit code d'identification et d'élément complémentaires d'accès à un ou plusieurs types d'informations d'au moins un serveur selon un protocole supporté par ledit réseau de télécommunication, d- de recherche par le serveur, des informations liées audit code d'identification et auxdits éléments complémentaires, e- de renvoi audit terminal mobile par ledit serveur des informations liées audit code d'identification et auxdits éléments complémentaires selon le protocole supporté par ledit réseau de télécommunicatio .The invention also relates to a method for obtaining information related to the location in the coverage area of a radio terminal of a mobile terminal connected to a telecommunications network connected to at least one server, characterized in that the terminal is independent of said telecommunications network and in that it comprises the steps: a- sending by said terminal of a unique identification code to said mobile terminal, according to a short distance radiocommunication protocol, b- registration by the mobile terminal of said unique identification code for subsequent consultation of the server, c- communication by the mobile terminal of said identification code and additional elements access to one or more types of information from at least one server according to a protocol supported by said telecommunications network, d- search by the server, information linked to said identification code and to said complementary elements, e- of returning to said mobile terminal by said server information linked to said identification code and to said additional elements according to the protocol supported by said telecommunication network.
Il comprend éventuellement l'étape préalable d'émission par le terminal mobile d'une commande selon un protocole de radiocommunication courte distance à destination de ladite borne radio.It optionally includes the prior step of transmitting by the mobile terminal a command according to a short-distance radiocommunication protocol intended for said radio terminal.
Selon une autre caractéristique de l'invention, le réseau comportant plusieurs serveurs, le code d'identification de la borne radio comporte des éléments de sélection d'un serveur. Le code d'identification comporte avantageusement des éléments relatifs à une caractéristique de la borne radio notamment celle concernant le titulaire de la borne radio et/ou la puissance d'émission de la borne radio.According to another characteristic of the invention, the network comprising several servers, the identification code of the radio terminal comprises elements for selecting a server. The identification code advantageously includes elements relating to a characteristic of the radio terminal, in particular that relating to the holder of the radio terminal and / or the transmission power of the radio terminal.
D'autres particularités et avantages de l'invention apparaîtront clairement à la lecture de la description faite à titre d'exemple non limitatif et en regard des dessins annexés sur lesquels : la figure 1 représente schématiquement une borne radio conforme à l'invention, la figure 2 illustre schématiquement le procédé de localisation selon l'invention, la figure 3 représente schématiquement un serveur, la figure 4 représente schématiquement un terminal mobile équipé d'un émetteur-récepteur BT, la figure 5 représente schématiquement un exemple de réalisation d'un terminal mobile dont les moyens de réception du code d'identification de la borne sont déportés .Other features and advantages of the invention will appear clearly on reading the description given by way of nonlimiting example and with reference to the appended drawings in which: FIG. 1 schematically represents a radio terminal according to the invention, the FIG. 2 schematically illustrates the location method according to the invention, FIG. 3 schematically represents a server, FIG. 4 schematically represents a mobile terminal equipped with a BT transceiver, FIG. 5 schematically represents an example of an mobile terminal whose means for receiving the terminal identification code are deported.
On va considérer dans la suite que le terminal mobile et la borne radio sont équipés de cellules BT. Plus généralement, toute autre cellule ou émetteur- récepteur permettant de communiquer selon un protocole de radiocommunication courte distance conviendrait, comme par exemple une cellule utilisant des composants radio transmettant dans la bande de fréquences des 5 GHz, dans la mesure où cette cellule peut communiquer un code d'identification unique par rapport aux autres codes d'identification connus.We will consider below that the mobile terminal and the radio terminal are equipped with LV cells. More generally, any other cell or transceiver making it possible to communicate according to a short-distance radiocommunication protocol would be suitable, such as for example a cell using radio components transmitting in the 5 GHz frequency band, insofar as this cell can communicate a unique identification code compared to other known identification codes.
Une borne radio 1 équipée d'une cellule BT 10, que l'on désignera par borne BT 1, est représentée figure 1.A radio terminal 1 equipped with a BT cell 10, which will be designated by BT terminal 1, is shown in Figure 1.
La cellule BT 10 comporte selon la technologie Bluetooth actuelle, une puce ou circuit intégré BT et un élément 104 d'alimentation en énergie. Une puce BT comprend notamment une ou plusieurs mémoires 101 contenant en particulier le code d'identification de la borne radio et le programme d'exécution des procédures prévues par le protocole BT permettant d'envoyer ou de recevoir des messages d'information ou de signalisation sur la couche physique du protocole (émission du code, authentification si nécessaire, ...) , un microprocesseur 102 pour exécuter les programmes, une interface d'entrée-sortie 103 associée à une antenne.The BT cell 10 comprises, according to current Bluetooth technology, a BT integrated circuit or chip and a power supply element 104. A BT chip notably includes one or more memories 101 containing in particular the identification code of the radio terminal and the program for carrying out the procedures provided for by the BT protocol making it possible to send or receive information or signaling messages on the physical layer of the protocol (transmission of the code, authentication if necessary, etc.), a microprocessor 102 for executing the programs, an input-output interface 103 associated with an antenna.
L'élément 104 peut être constitué d'une pile éventuellement rechargeable au moyen de cellules photoélectriques ou par induction ou conduction électrique à travers un transformateur. L'alimentation en énergie peut être obtenue par un accès direct à une source d'énergie 11. L'accès à cette source électrique peut prendre la forme d'une prise électrique, mâle ou femelle. Il peut aussi s'agir d'un accès à un équipement électrique auquel la borne BT 1 est intégrée et dont elle partage les fonctions d'alimentation en énergie, de fixation voire de protection.The element 104 may consist of a battery, possibly rechargeable by means of photoelectric cells or by induction or electrical conduction through a transformer. The energy supply can be obtained by direct access to an energy source 11. Access to this electrical source can take the form of an electrical outlet, male or female. It can also be access to electrical equipment in which the LV terminal 1 is integrated and of which it shares the functions of power supply, fixing or even protection.
La borne BT 1 comporte éventuellement un élément de dissipation 12 de l'énergie, tel qu'un dispositif électrique (ampoule électrique, ...) . Bien sûr, le système de localisation à proximité d'une borne BT 1 selon l'invention est d'autant plus intéressant que des bornes BT 1 sont installées à grande échelle sur une zone géographique selon un maillage plus ou moins serré en fonction du service attendu. Une telle installation est facilitée en particulier par le bas coût de ces bornes BT et leur faible encombrement. Dans la mesure où elles ne sont pas reliées à un réseau d'accès, elles peuvent être installées par toute personne ou entité privée ou publique souhaitant créer et déployer son propre maillage.The LV terminal 1 possibly includes an energy dissipation element 12, such as an electrical device (light bulb, etc.). Of course, the location system near a BT 1 terminal according to the invention is all the more advantageous as BT 1 terminals are installed on a large scale in a geographical area according to a more or less tight grid depending on the service expected. Such an installation is facilitated in particular by the low cost of these LV terminals and their small size. Insofar as they are not connected to an access network, they can be installed by any person or private or public entity wishing to create and deploy their own network.
Un opérateur public choisira d'installer ces bornes BT dans des lieux permettant d'éviter vols et vandalisme tout en facilitant une maintenance courante. Dans les villes, les feux tricolores, les lampadaires, certains panneaux de signalisation, certains équipements protégés reliés ou non à une alimentation électrique existante, certains bâtiments ou monuments publics correspondent à ces critères . Pour les lieux ne fournissant pas d'accès facile au réseau électrique comme sur certains réseaux routiers, des bornes BT autonomes utilisant des piles rechargeables seront utilisées. Un organisme privé (zone portuaire, raffinerie, entrepôt géant, ...) ou un particulier pourra souhaiter utiliser les bornes existantes installées par un opérateur public ou une autre entité, ou compléter le maillage existant par des bornes qu'il installera lui- même. L'intérêt d'un tel complément est d'obtenir un maillage plus fin permettant d'améliorer les possibilités d'accès au serveur et/ou d'accéder, comme on le verra plus loin, à un serveur fournissant un complément d' informations par rapport aux informations de base. Comme représenté figure 2 , le procédé de localisation du terminal mobile 2, en l'occurrence un radiotéléphone comprend les principales étapes suivantes : a- émission, selon le protocole BT, par le terminal mobile 2 d'une commande d'identification à destination de la borne BT 1 ; et, dans la mesure où la borne BT 1 ou plus précisément la cellule BT 10, a reçu cette commande c'est-à-dire est située dans une bulle 13 de rayon inférieur à 100 m voire inférieur à 10 m du terminal 2 (le rayon dépendant de la puissance d'émission des puces BT et de la sensibilité du récepteur recevant le signal émis) , réponse par la borne BT 1 de son code d'identification, selon le protocole BT à destination du (ou des) terminal (terminaux) mobile (s) 2 se situant dans sa zone de couverture 13. Lorsque le terminal mobile 2 est situé dans la zone de couverture 13 de plusieurs bornes BT 1, il reçoit plusieurs codes d'identification.A public operator will choose to install these LV terminals in places that prevent theft and vandalism while facilitating routine maintenance. In cities, traffic lights, lampposts, certain traffic signs, certain protected equipment connected or not to an existing electrical supply, certain buildings or public monuments correspond to these criteria. For places that do not provide easy access to the electrical network, such as on certain road networks, autonomous LV terminals using rechargeable batteries will be used. A private organization (port area, refinery, giant warehouse, ...) or an individual may wish to use the existing terminals installed by a public operator or another entity, or supplement the existing network with terminals that he will install himself . The advantage of such a complement is to obtain a finer mesh making it possible to improve the possibilities of accessing the server and / or accessing, as will be seen below, a server providing additional information in relation to the basic information. As shown in FIG. 2, the method for locating the mobile terminal 2, in this case a radiotelephone comprises the following main steps: a- transmission, according to the BT protocol, by the mobile terminal 2 of an identification command to terminal BT 1; and, insofar as the terminal BT 1 or more precisely the BT cell 10, has received this command, that is to say is located in a bubble 13 with a radius less than 100 m or even less than 10 m from terminal 2 ( the radius depends on the transmission power of the BT chips and on the sensitivity of the receiver receiving the transmitted signal), response by terminal BT 1 of its identification code, according to the BT protocol intended for the terminal (s) ( terminals) mobile (s) 2 located in its coverage area 13. When the mobile terminal 2 is located in the coverage area 13 of several LV terminals 1, it receives several identification codes.
Selon un autre mode de réalisation, la borne BT 1 émet à intervalles réguliers son code d'identification sans avoir à être interrogée par un terminal mobile 2. b- communication par le terminal mobile 2 du (ou des) code (s) d'identification au serveur 3 selon un protocole (Internet, WAP ou autre) supporté par le réseau de télécommunication 4 tel que le réseau RTC (Réseau Téléphonique Commuté) , ADSL (Asymmetric Digital Subscriber Line) , GSM, UMTS, GPRS (General Packet Radio Services) , ou autre, auquel est relié le terminal mobile 2 ; c- recherche dans la base de données du serveur 3 des informations liées au(x) code (s) d'identification de la (des) borne(s) BT 1, fourni (s) par le terminal mobile 2 ; calculs ou traitements éventuels pour obtenir d'autres informations comme par exemple, lorsque plusieurs codes d'identification ont été fournis, calcul de la position du terminal mobile 2 se situant à 1 ' intersection des zones de couverture des bornes BT identifiées ; des informations liées notamment à la facturation peuvent éventuellement être envoyées vers un centre de traitement d'informations du réseau 4, d- renvoi au terminal mobile 2 par le serveur 3 des informations de localisation telles que précédemment décrites, selon un protocole de télécommunication.According to another embodiment, the terminal BT 1 transmits its identification code at regular intervals without having to be interrogated by a mobile terminal 2. b- communication by the mobile terminal 2 of the code (s) identification to the server 3 according to a protocol (Internet, WAP or other) supported by the telecommunications network 4 such as the PSTN (Switched Telephone Network), ADSL (Asymmetric Digital) network Subscriber Line), GSM, UMTS, GPRS (General Packet Radio Services), or other, to which the mobile terminal 2 is connected; c- search in the database of the server 3 for information linked to the identification code (s) of the terminal (s) BT 1, supplied by the mobile terminal 2; calculations or possible treatments to obtain other information such as for example, when several identification codes have been provided, calculation of the position of the mobile terminal 2 located at one intersection of the coverage areas of the identified LV terminals; information related in particular to billing can optionally be sent to an information processing center of the network 4, d- return to the mobile terminal 2 by the server 3 of the location information as previously described, according to a telecommunication protocol.
Une étape complémentaire peut intervenir après réception par le terminal mobile 2 , des informations de localisation comportant par exemple un signet : e- introduction de ce signet dans le terminal mobile 2 et envoi directement ou via un ordinateur personnel 5, vers un serveur 6 Internet ou autre en vue d'obtenir les informations souhaitées.A complementary step may take place after reception by the mobile terminal 2, of location information comprising for example a bookmark: e- introduction of this bookmark in the mobile terminal 2 and sending directly or via a personal computer 5, to a server 6 Internet or other in order to obtain the desired information.
Le code d'identification, codé sur 48 bits pour la norme BT (ce qui correspond à 16 puissance 12 possibilités de codes d'identification différents, soit 281000 milliards de possibilités) comporte l'identification de la borne BT 1. Le code d'identification, fourni par l'industriel, est propre à chaque borne BT 1 : il est unique quel que soit le nombre de bornes BT 1 installées sur une zone géographique et pouvant atteindre plusieurs dizaines de millions de bornes BT.The identification code, coded on 48 bits for the BT standard (which corresponds to 16 power 12 possibilities of different identification codes, that is 281000 billion possibilities) includes the identification of the terminal BT 1. The code identification, provided by the manufacturer, is specific to each LV 1 terminal: it is unique regardless of the number of LV 1 terminals installed in a geographic area and which may reach several tens of millions of LV terminals.
Ainsi, le code d'identification bluetooth décrit dans la présente invention est déjà industrialisé, unique et se trouve implicitement dans tous les équipements bluetoothés. Cette caractéristique de l'unicité du code d'identification bluetooth permet d'utiliser n'importe où (dans le monde entier) une puce bluetooth sans avoir à lui forcer un code d'identification le prélocalisant. L'unité du code d'identification BT entraîne la possibilité de réaliser une bijection avec une base (ou plusieurs bases) de données .Thus, the bluetooth identification code described in the present invention is already industrialized, unique and is found implicitly in all bluetooth devices. This characteristic of the uniqueness of the bluetooth identification code makes it possible to use anywhere (worldwide) a bluetooth chip without having to force an identification code to pre-locate it. The unit of the BT identification code gives rise to the possibility of carrying out a bijection with a database (or several databases).
Il existe diverses catégories de bornes BT 1 définies en fonction par exemple de 1 ' étendue de la zone (ou bulle) de couverture 13 de chaque borne BT 1 : par exemple les deux catégories correspondant à des puissances d'émission différentes (1 milliwatt, 100 milliwatts) auxquelles peuvent être corrélées, du fait des récepteurs usuels utilisés, des zones de couverture de 10m et 100m. Lorsque plusieurs catégories de bornes BT 1 sont installées, le code d'identification peut éventuellement comporter des caractères relatifs à la catégorie correspondante, ce qui facilitera la localisation du terminal mobile 2.There are various categories of LV 1 terminals defined as a function for example of the extent of the area (or bubble) of coverage 13 of each LV 1 terminal: for example the two categories corresponding to different transmission powers (1 milliwatt, 100 milliwatts) to which can be correlated, due to the usual receivers used, coverage areas of 10m and 100m. When several categories of LV terminals 1 are installed, the identification code may possibly include characters relating to the corresponding category, which will make it easier to locate the mobile terminal 2.
Différents types d'informations sauvegardées dans le serveur 3, peuvent être liés à la borne BT 1. Ces informations sont par exemple structurées sous la forme d'une matrice d'éléments (i,j) tels qu'au code d'identification de la borne BT i (i variant de 1 au nombre de codes identifiés dans le serveur) est associée le type d'informations j (j variant de 1 au nombre de types d'informations sauvegardées sur le serveur) .Different types of information saved in the server 3 can be linked to the BT terminal 1. This information is for example structured in the form a matrix of elements (i, j) such as the identification code of the terminal BT i (i varying from 1 to the number of codes identified in the server) is associated with the type of information j (j varying from 1 to the number of types of information saved on the server).
Outre des informations de localisation géographique qui peuvent être présentées sous différents formats ( « ... de longitude Nord, ... de latitude Ouest », « 5è étage du ... de la rue X », « code A5B8 », ...) , il peut s'agir d'informations touristiques ("L'immeuble construit en 1895 présente une architecture ..."), publicitaires (" 20% de remise dans la boutique ..."), de loisirs ("programme du cinéma situé 16 rue ...", "horaires d'ouverture de la bibliothèque située ...) , de signets Internet permettant d'accéder à un service Internet, notamment un service commercial .In addition to geographic location information which can be presented in different formats ("... North longitude, ... West latitude", "5th floor of ... X street", "A5B8 code", .. .), it can be tourist information ("The building built in 1895 has an architecture ..."), advertising ("20% discount in the shop ..."), leisure ("program the cinema located at 16 rue ... "," opening hours of the library located ...), Internet bookmarks allowing access to an Internet service, in particular a commercial service.
L'invention constitue donc véritablement un système d'obtention d'informations à partir de bornes radio, fixes ou mobiles, capable d'émettre selon un protocole de type BT, de préférence sur requête, un identifiant unique. L'unicité du code d'identification de chacune des bornes radio garantie par l'industriel est une composante primordiale de 1 ' invention permettant une grande richesse en informations accessibles.The invention therefore truly constitutes a system for obtaining information from radio terminals, fixed or mobile, capable of transmitting according to a BT type protocol, preferably on request, a unique identifier. The uniqueness of the identification code of each of the radio terminals guaranteed by the manufacturer is a key component of the invention allowing a wealth of accessible information.
L ' ensemble de ces informations peut être systématiquement communiqué par le serveur 3 au terminal mobile 2. Néanmoins, elles sont de préférence sélectionnées par l'utilisateur du terminal mobile 2 qui fournit au serveur 3 en plus du code d'identification, des éléments complémentaires relatifs à son choix de type d'information. Le serveur 3 peut par exemple renvoyer au terminal mobile 2 les informations de base liées au code d'identification de la borne BT 1 et un menu proposant les différents types d'informations possibles. L'utilisateur communique alors via son terminal mobile 2, son choix au serveur 3 qui en retour, lui envoie les informations correspondantes. De manière avantageuse, l'utilisateur enregistre son choix dans son terminal mobile 2 en vue d'une utilisation ultérieure automatique : le choix d'un type d'informations sera alors par exemple fourni en même temps que le code d'identification.All of this information can be systematically communicated by the server 3 to the mobile terminal 2. However, it is preferably selected by the user of the mobile terminal 2 who supplies the server 3 in addition to the identification code, additional elements relative to its choice of type of information. The server 3 can for example send back to the mobile terminal 2 the basic information linked to the identification code of the terminal BT 1 and a menu proposing the different types of possible information. The user then communicates via his mobile terminal 2, his choice to the server 3 which in return sends him the corresponding information. Advantageously, the user saves his choice in his mobile terminal 2 with a view to automatic subsequent use: the choice of a type of information will then be provided, for example, at the same time as the identification code.
Des informations de sécurité ou confidentielles peuvent aussi être sauvegardées dans le serveur 3 : elles sont accessibles à partir de certains codes d'identification de bornes BT 1 à usage privé par exemple ou à partir du code d'identification d'une borne BT 1 à usage public, assorti d'éléments complémentaires (code confidentiel éventuellement biométrique si le terminal mobile le permet, authentification par un scanneur, une carte à puce, ...) permettant au serveur 3 d'authentifier et de valider 1 ' accès à ces informations . Ces éléments complémentaires peuvent être fournis par le terminal mobile 2, en même temps que le code d'identification ou suite à une demande du serveur 3 comme dans le cas précédent du choix d'un type d'informations.Security or confidential information can also be saved in the server 3: they are accessible from certain identification codes of BT terminals 1 for private use for example or from the identification code of a BT terminal 1 to public use, with additional elements (possibly biometric confidential code if the mobile terminal allows, authentication by a scanner, a smart card, etc.) allowing the server 3 to authenticate and validate access to this information . These additional elements can be provided by the mobile terminal 2, at the same time as the identification code or following a request from the server 3 as in the previous case of the choice of a type of information.
Les informations sauvegardées dans le serveur 3 sont mises à jour par l'opérateur du serveur, voire par celui qui a installé la borne BT 1. Cette mise à jour peut par exemple être réalisée en ligne, par Internet ou en différé en mode "batch" permettant de regrouper un grand nombre de mises à jour.The information saved in the server 3 is updated by the server operator, or even by the person who installed the BT terminal 1. This update can for example be carried out online, by Internet or deferred in "batch" mode allowing to group a large number of updates.
Le serveur 3 représenté figure 3 , comporte de manière classique une base de données 31, une unité centrale 32 mettant en œuvre un programme d'accès aux données et/ou de modification des données, éventuellement un programme de calcul sur les données et une interface d'entrée-sortie 33 apte à communiquer avec ledit terminal mobile 2. Ce serveur 3 a de préférence une grande capacité (quelques gigaoctets) afin de pouvoir héberger de nombreux types d'informations (plusieurs milliers) et afin de pouvoir traiter simultanément plusieurs requêtes. Aussi, ce serveur n'est-il pas nécessairement unique. Dans le cas où plusieurs serveurs sont utilisés, chaque serveur peut être attribué à une zone géographique, ou être sélectionné par des caractères spécifiques du code d'identification des bornes BT ou associé à un type d'informations. Certains serveurs peuvent être privés, sous le contrôle de l'organisme privé ayant installé des bornes BT dans une zone privée. Certains sont mixtes dans la mesure où ils hébergent des informations publiques et des informations privées accessibles par certains codes d'identification et/ou par un code confidentiel comme décrit plus tôt.The server 3 represented in FIG. 3, conventionally comprises a database 31, a central unit 32 implementing a data access and / or data modification program, possibly a calculation program on the data and an interface input-output 33 capable of communicating with said mobile terminal 2. This server 3 preferably has a large capacity (a few gigabytes) in order to be able to host many types of information (several thousand) and in order to be able to simultaneously process several requests . Also, this server is not necessarily unique. In the case where several servers are used, each server can be assigned to a geographic area, or be selected by specific characters from the identification code of the BT terminals or associated with a type of information. Some servers can be private, under the control of the private organization that installed LV terminals in a private area. Some are mixed insofar as they host public and private information accessible by certain identification codes and / or by a confidential code as described earlier.
Les informations données par un organisme public sont avantageusement mises en valeur par un format ou un effet d'écriture quelconque qui permet d'en distinguer la provenance. De même une borne radio installée par l'organisme public comporte de préférence un système de sécurité éventuellement mécanique désactivant ou neutralisant automatiquement l'émetteur de la borne radio, au cas où la borne radio serait indûment déplacée.The information given by a public body is advantageously enhanced by any format or writing effect which makes it possible to distinguish its source. Similarly, a radio terminal installed by the public body preferably includes a possibly mechanical security system automatically deactivating or neutralizing the transmitter of the radio terminal, in case the radio terminal is unduly moved.
La borne BT 1 peut être déplacée, voire même installée sur un équipement mobile tel qu'un véhicule. Le téléphone mobile 2 se trouvant alors dans la zone de couverture de cette borne BT 1, reçoit puis envoie au serveur 3 le code d'identification de cette borne BT 1. Les informations liées à ce code d'identification ne sont pas liées à l'adresse géographique de la borne BT 1 puisque celle-ci est mobile mais peuvent par exemple être du type : « Véhicule appartenant à M. X, résidant ... » ou « Véhicule volé le ... ». Dans ce cas, comme dans le cas plus général où la borne BT 1 est installée sur un équipement mobile, les informations liées au code d'identification de la borne BT 1, peuvent être des informations d'identification, d' authentification ou d'appartenance, permettant l'accès à toutes sortes de services, en particulier de sécurité (récupération ou signalisation d'objets volés) et de paiement (parcmètres, péages routiers) .The BT 1 terminal can be moved or even installed on mobile equipment such as a vehicle. The mobile telephone 2 then being in the coverage area of this BT terminal 1, receives then sends to the server 3 the identification code of this BT terminal 1. The information linked to this identification code is not linked to the 'geographic address of terminal BT 1 since it is mobile but can for example be of the type: "Vehicle belonging to Mr. X, resident ..." or "Vehicle stolen on ...". In this case, as in the more general case where the BT 1 terminal is installed on a mobile device, the information linked to the identification code of the BT 1 terminal, may be identification, authentication or authentication information. membership, allowing access to all kinds of services, in particular security (recovery or reporting of stolen objects) and payment (parking meters, road tolls).
Afin de pouvoir communiquer avec la borne BT 1 d'une part et avec le réseau de télécommunication 4 auquel il est relié, et comportant notamment le serveur 3, le terminal mobile 2 est lui-même équipé comme représenté figure 4, d'une cellule BT 21 reliée à des moyens 22 pour communiquer avec le réseau, connus de l'homme du métier. Les moyens 22 de communication permettent notamment de retransmettre le code d'identification au serveur 3 et de recevoir du serveur 3 les informations liées à ce code d'identification. Les moyens fonctionnels de la cellule BT 21 dont la structure est identique à celle schématiquement représentée figure 1, référence 10, comprennent avantageusement, outre des moyens de réception 210 des codes d'identification et d'émission 211 d'une commande d'identification, des moyens d'enregistrement (ou de mémorisation) 212 des codes. Le code d'identification mémorisé permet de consulter ultérieurement le serveur, accessible selon le même processus que décrit précédemment mais également, sans s'y limiter, via le réseau Internet, en utilisant les moyens usuels tels que l'ADSL, le RTC, le câble ou le NGN (Next Génération Network) . Ainsi, les moyens d'enregistrement permettent une consultation de l'information en temps différé. De cette façon, une fois que le code d'identification de la borne est sauvegardé, il peut y avoir n'importe où et n'importe quand consultation de l'information liée au code d'identification unique enregistré. La mise en œuvre de la présente invention n'implique donc aucune contrainte géographique ou territoriale.In order to be able to communicate with the terminal BT 1 on the one hand and with the telecommunications network 4 to which it is connected, and comprising in particular the server 3, the mobile terminal 2 is itself equipped as shown in FIG. 4, with a cell BT 21 connected to means 22 for communicating with the network, known to those skilled in the art. The communication means 22 make it possible in particular to retransmit the identification code to the server 3 and to receive from the server 3 the information linked to this identification code. The functional means of the LV cell 21, the structure of which is identical to that schematically represented in FIG. 1, reference 10, advantageously comprise, in addition to means for receiving 210 identification codes and transmission 211 of an identification command, means for recording (or memorizing) 212 the codes. The memorized identification code allows later consultation of the server, accessible according to the same process as described above, but also, without being limited to, via the Internet, using the usual means such as ADSL, PSTN, cable or NGN (Next Generation Network). Thus, the recording means allow consultation of the information in deferred time. In this way, once the terminal identification code is saved, there can be anytime and anywhere consultation of the information linked to the registered unique identification code. The implementation of the present invention therefore does not imply any geographical or territorial constraint.
Les moyens fonctionnels de la cellule BT 21 comportent avantageusement des détecteurs du niveau du signal reçu par le terminal mobile 2 et provenant de la borne BT 1, ce niveau étant lié en particulier à la puissance de la borne BT 1 et à la distance entre l'émetteur du signal c'est-à-dire la borne BT 1 et le récepteur de ce signal c'est-à-dire le terminal mobile 2. Une estimation de cette distance, avantageusement calculée par le serveur en fonction de paramètres fournis par le terminal mobile, permet ainsi de localiser avec encore plus de précision le terminal mobile 2 dans la zone (la bulle) de couverture 13 de la borne BT 1.The functional means of the LV cell 21 advantageously comprise detectors of the level of the signal received by the mobile terminal 2 and coming from the BT terminal 1, this level being linked in particular to the power of the BT terminal 1 and to the distance between the transmitter of the signal, that is to say the terminal BT 1 and the receiver of this signal, that is to say the mobile terminal 2. An estimate of this distance, advantageously calculated by the server as a function of parameters supplied by the mobile terminal, thus makes it possible to locate the terminal even more precisely mobile 2 in the area (the bubble) of cover 13 of the LV terminal 1.
Comme représenté figure 5, les moyens de réception 210 de la cellule BT 21 ou la cellule BT 21 elle-même peuvent être déportées sur un équipement mobile tel qu'un robot mobile 24 relié par une connexion 23 filaire ou autre (un système radio BT ou autre par exemple) à un dispositif équipé des moyens 22 de communication avec le serveur 3. La connexion 23 peut être une connexion BT, lorsque le dispositif de télécommunication 22 étant lui-même équipé d'une puce BT, la puissance d'émission réception entre la puce BT 21 et la puce BT du dispositif de télécommunication 22 est beaucoup plus forte (100 milliwatts par exemple) que celle utilisée (1 milliwatt ou moins) sur les puces BT jalonnant le parcours du robot .As shown in Figure 5, the receiving means 210 of the BT cell 21 or the BT cell 21 itself can be deported to mobile equipment such as a mobile robot 24 connected by a wired or other connection 23 (a BT radio system or other for example) to a device equipped with means 22 for communicating with the server 3. Connection 23 can be a LV connection, when the telecommunication device 22 is itself equipped with a BT chip, the transmission power reception between the BT chip 21 and the BT chip of the telecommunication device 22 is much stronger (100 milliwatts for example) than that used (1 milliwatt or less) on the BT chips marking out the path of the robot.
Une telle configuration répartie en deux dispositifs présente un intérêt en milieu hostile ou difficile d'accès : milieu marin, conduites enterrées, zone de haute sécurité (centrale atomique, ...) , etc.Such a configuration divided into two devices is of interest in hostile or difficult to access environments: marine environment, buried pipes, high security zone (atomic power plant, etc.), etc.
Le terminal mobile 2 peut être un radiotéléphone ou un agenda personnel ou un ordinateur personnel ou tout autre équipement disposant d'une cellule BT et d'une capacité logicielle, informatique et de communication permettant d'émettre et/ou de recevoir des commandes et/ou des requêtes BT, d'envoyer les résultats (à savoir au moins le code d'identification de la cellule BT d'une borne captée) , sur un équipement distant via le réseau de télécommunication auquel le terminal mobile est relié, ou de les sauvegarder pour des traitements ultérieurs à effectuer sur des équipements adaptés. De telles sauvegardes permettent de réaliser par exemple des enregistrements de parcours (pour des contrôles ou suivis de rondes de sécurité ou autres) , ou des accumulations pertinentes de données pour la réalisation par exemple de montages video ou même photographiques.The mobile terminal 2 can be a radiotelephone or a personal agenda or a personal computer or any other equipment having a LV cell and a software, IT and communication capacity making it possible to send and / or receive commands and / or BT requests, to send the results (namely at least the identification code of the BT cell of a received terminal), to a remote device via the telecommunications network to which the mobile terminal is connected, or to save for subsequent treatments to be carried out on suitable equipment. Such backups make it possible to carry out, for example, course recordings (for controls or monitoring of security patrols or the like), or relevant accumulations of data for the production, for example of video or even photographic montages.
Enfin, un mode particulier de fonctionnement de l'invention consiste à mettre en œuvre une extraction de la base de données d'au moins un serveur sur l'équipement particulier doté d'une cellule BT comme précédemment décrit . Il est alors possible de consulter cette base sans avoir besoin de communiquer avec un serveur via un réseau de télécommunication. L'extraction de la base peut se faire de chez soi, selon des critères géographique (carte électronique avec tous les points fixes possédant un identifiant bluetooth localisés) ou d'intérêt particulier (ce mode de fonctionnement pourrait s'appliquer par exemple au cas des véhicules volés qu'un agent pourrait localiser grâce à son terminal mobile où les identifiants bluetooth de tous les véhicules volés non encore retrouvés auraient été enregistrés) . Finally, a particular mode of operation of the invention consists in implementing an extraction of the database from at least one server on the particular item of equipment provided with a LV cell as previously described. It is then possible to consult this database without the need to communicate with a server via a telecommunications network. The extraction of the base can be done from home, according to geographic criteria (electronic card with all the fixed points having a bluetooth identifier located) or of particular interest (this mode of operation could apply for example in the case of stolen vehicles that an agent could locate using his mobile terminal where the bluetooth identifiers of all stolen vehicles not yet found have been recorded).
