Technical field

TECHNICAL FIELD [0001] The present invention relates to a technique for acquiring position information by referring to a position information table, and in particular, an IP telephone device using VoIP and its incoming call function, and a route that provides route information to a destination. The present invention relates to an information guidance system.

Background art

[0002] Due to the widespread use of broadband Internet such as ADSL (Asymmetric Digital Subscriber Line) and optical fiber, and the development of VoIP (voice over Internet Protocol) technology for transmitting voice over IP (Internet Protocol) IP telephones using the Internet network are widely used. IP phone calls can be made in three ways: calls between personal computers, calls between personal computers and ordinary telephones, and calls between ordinary telephones.

[0003] An IP telephone system will be described with reference to FIG. A case where a call is made from the analog telephone 83 on the calling side to the analog telephone 89 on the called side will be described. The calling side analog telephone 83 converts the voice into an analog signal and transmits it to the VoIP gateway 84. The VoIP gateway 84 converts an analog signal into a digital signal and generates an IP packet signal. The IP packet signal is sent to the IP network via the router 85, and, like a normal IP packet, the destination IP address is referred to and transferred one after another to reach the called router 87.

[0004] The router 87 on the called side transmits an IP packet signal to the VoIP gateway 88 on the called side.

The VoIP gateway 88 converts the digital signal to an analog signal and transmits it to the analog telephone 89 on the called side, contrary to the operation of the VoIP gateway 84 on the calling side. The analog telephone 89 converts an analog signal into sound.

[0005] Instead of the analog telephone 83 and the VoIP gateway 84, a personal computer or portable communication terminal equipped with IP telephone software, or an IP telephone may be used.

[0006] In the IP telephone system, as shown in the figure, a call control server 81 for performing "call control" is provided. The call control server 81 is a data table that is a correspondence table between telephone numbers and IP addresses. 82. The call control server 81 performs user authentication with the VoIP gateways 84 and 88, management of telephone numbers and IP addresses, management of billing information, and the like. The VoIP gateways 84 and 88 perform “call control” for calling the other party and managing calls. “Call control protocol” is used for “call control”. Various types of protocols such as H.323, SIP, and MEGACO are known as “call control protocols”.

[0007] A call control sequence will be briefly described. When the calling VoIP gateway 84 receives a call from the calling analog telephone 83, it first checks with the call control server 81 whether or not the call can be made with the other party. Communicates about number and IP address conversion. Next, the call control server 81 confirms whether or not a call with the other party can be made with the VoIP gateway 88 on the called side. When the callee confirms that the call can be received, a call is made from the caller to the callee, and control information such as actual call and call session management information is exchanged. Is called.

[0008] Telephones such as mobile phones and fixed phones currently used are provided with various functions in addition to voice calls. For example, the phonebook function provided on the telephone can be used to change the ringtone according to the caller.

[0009] Furthermore, if the called party cannot answer, the answering function may be provided by the answering machine function provided on the telephone. An answering service provided by the telephone operator may be used instead of the answering machine function provided on the telephone. Some telephone operators provide a service to forward to a designated telephone number (cell phone, landline, PHS, etc.).

[0010] Conventionally, a car navigation system is known as a route information guidance system that searches for a route to a destination and displays the searched route information on a display device. The car navigation system is a system that displays the current position on the map screen of the car computer and guides the route to the destination, and is used in the vehicle.

[0011] Further, as route information guidance systems that can be used not only for vehicles but also for bicycles and pedestrians, those described in Patent Documents 3 and 4 are known.

[0012] On the other hand, in recent years, along with the development of short-range (proximity) communication technologies such as wireless LAN (Local Area Network) such as Bluetooth and IEEE802.x, notebook PCs (Personal Computers) and PDAs ( Various devices such as Personal Digital Assistant) are equipped with a proximity wireless communication function, enabling cordless communication and cordless Internet connection (LAN connection) between each device.

[0013] As one of the usage forms of Bluetooth, which is one of such proximity communication technologies, an information transmission device called a terminal device is installed at a predetermined location, and when a user passes near the installation position. As a route information guidance system that provides information indicating the current position of a mobile device possessed by a user and information on the way of the route, the one described in Patent Document 5 is considered.

[0014] As a use form of wireless LAN, a communication base station called an access point is installed at a predetermined location, and a wireless LAN connection environment is provided by communication connection between a mobile device owned by a user and the communication base station A service called a hotspot is provided, and a service that obtains the current position by measuring the radio field strength of the wireless LAN is also considered.

BEST MODE FOR CARRYING OUT THE INVENTION

With reference to FIG. 1, an example of an IP telephone automatic answering device according to the first embodiment of the present invention will be described. The IP telephone automatic answering apparatus according to the present embodiment has a VoIP terminal 10 and a database 20. The VoIP terminal 10 includes an IP telephone unit 11, a display unit 12 for displaying the set response method and database information, and an input unit 13 for setting the response method and operating the outgoing call Z incoming call of the VoIP terminal 10. And having. The IP telephone unit 11 includes a VoIP unit 111 having an IP telephone function, and an automatic response switching unit 112 that automatically switches a response method when a call is received.

[0031] The database 20 includes first and second response method tables 21 and 22, first and second schedule tables 23 and 24, fixed response message data 25, and message data (answering machine) 26. . Data registered in the standard response message data 25 and data stored in the message data (answering machine) 26 can be in any data format such as voice / text 'image'.

FIG. 1 shows one VoIP terminal 10 and one database 20, but the IP telephone automatic answering device of this example includes a plurality of VoIP terminals 10 and one database 20. It may be configured as follows. The database 20 can be installed in any format as long as it can be referenced from all VoIP terminals 10. For example, it may be provided on a network.

[0033] The VoIP terminal 10 may be a fixed terminal such as a subscriber phone or a computer, but may be a portable or mobile terminal such as a mobile phone or PDA. However, in the following description, it is assumed that the V◦IP terminal 10 is a mobile terminal.

In the first response method table 21, as shown in FIG. 3, the relationship between the position information table and the response method is registered. In the second response method table 22, as shown in FIG. 7, the relationship between the urgency level and the response method is registered. In the first schedule table 23, the relationship between the time information table and the schedule is registered as shown in FIG. 4, and in the second schedule table 24, the time information table and the schedule are registered as shown in FIG. Relationships, and even group I D and registrant name are registered. In the standard response message data 25, a standard message to be sent to the caller is registered. In the message data (answering machine) 26, a message transmitted from the caller is stored. The first and second response method tables 21 and 22, the first and second schedule tables 23 and 24, and the standard response message data 25 are input in advance by the user. Details of the response method using these tables are described below.

With reference to FIG. 2, an example of an IP telephone system using the IP telephone automatic answering apparatus according to the present invention will be described. A network is provided in each of the living room, the conference room, and the dining room, and these are called the living room network 410, the conference room network 420, and the dining room network 430, respectively. In each network, routers 41, 42, and 43 are arranged and connected to the Internet 200 via the router.

[0036] An IP address is assigned to each VoIP terminal. An IP address consists of a network address and a host address. The network address is the part of the IP address that identifies the network, and the host address is all "0". The room network 410, the conference room network 420, and the cafeteria network 430 are assigned different network addresses and are identified as different network segments.

Therefore, the network address indicates the installation position of the router. In addition, the network address indicates the current location of the VoIP terminal. The network address uniquely corresponds to the current location of the router and VoIP terminal!

Consider a case in which a VoIP terminal 411 existing in the room network 410 is called from the calling VoIP terminal 401. An outgoing call from the VoIP terminal 401 is sent to the Internet 200 via the router 40 and transferred to the called VoIP terminal 411 via the router 41. The VoIP terminal 41 1 detects the network address from the IP address of its own VoIP terminal 411 or the calling VoIP terminal 401. Furthermore, referring to the database 20, the response method corresponding to the network address is obtained. The automatic response switching unit 112 performs incoming call processing or incoming call processing according to the response method.

Thus, in this example, the called VoIP terminal 411 performs response processing according to the current position of the called VoIP terminal 411 or the calling VoIP terminal 401. FIG. 3 shows an example of the first response method table 21. The response method table 21 of this example includes a location information table and a response method of the called side corresponding to the location information table. The location information table includes the correspondence between network addresses and router installation locations. As explained with reference to Figure 2, the relationship between the network address and the router installation location is uniquely determined. The automatic response switching unit 112 of the called VoIP terminal refers to the response method table 21 and extracts the response method based on the network address of the called side or the calling side.

[0041] Response methods on the called side include “incoming call”, “standard response message”, “reference to schedule table”, and the like. The user selects a suitable one for the position from the list of response methods prepared in advance, and registers it. When “Receiving” is set as the answering method, normal IP phone call processing is performed. This is assumed, for example, when the called party is available. “Standard response message” is set as the response method! In the case of speaking, the standard response message data 25 stored in the database is transmitted to the VoIP terminal 401 on the calling side. This assumes, for example, a case where the called party cannot respond. When a message message is transmitted from the calling VoIP terminal 401 in response to the standard response message, the content is stored in the message data (answering machine) 26 of the database.

[0042] When "Refer to the first schedule table" is set as the response method !, the automatic response switching unit 112 refers to the first schedule table 23 on the database. When “refer to second schedule table” is set as the response method !, automatic response switching unit 112 refers to second schedule table 24 on the database.

An example of the first schedule table 23 will be described with reference to FIG. The schedule table 23 in this example includes a time information table and a corresponding “schedule” of the called party. The time information includes “date information” and “time information”. The schedule contains the contents of the schedule for meetings, meetings, etc. The schedule may be created by a character string input by the user who may select from a list of schedules prepared in advance.

The automatic response switching unit 112 acquires the schedule registered in the “date information” and “time information” fields corresponding to the time of incoming call. The acquired schedule is sent as response message data to the calling VoIP terminal. This response message is spoken 'text as described above • Regardless of the data format such as images. If “schedule” is not registered in the “date information” and “time information” fields corresponding to the current time, the automatic response switching unit 112 refers to the first response method table 21. Get the response method.

Next, an example of the second schedule table 24 will be described with reference to FIG. The schedule table 24 of this example is different from the first schedule table 23 of FIG. 4 in that the schedules of other members of the transfer destination are also registered! The schedule table 24 in this example includes a group ID, a registered name, an IP phone number, a transfer priority, and a destination in addition to the time information table and the caller's schedule.

“Destination” indicates a new U or location when the VoIP terminal moves to another network.

The setting method of “Destination” will be described later.

[0047] The automatic answer switching unit 112 determines whether or not the caller's own "schedule" is registered in the "date information" and "time information" fields corresponding to the time of the incoming call. To do. When the schedule is not registered for the called party himself / herself, the automatic response switching unit 112 refers to the first response method table 21 and acquires the response method.

[0048] When the schedule is registered with the called party himself / herself, first, a registered person name having the same group ID as the called party is searched. Next, from these registrants, the “date” and “time information” fields corresponding to the time of the incoming call are registered in the “date information” and “time information” fields, and the registrant who is supposed to be registered is selected as the forwarding destination. The transfer destination registrant name, IP telephone number, transfer priority, destination and fixed response message data thus selected are transmitted to the calling VoIP terminal 401.

FIG. 6 shows a transfer selection screen displayed on the display unit 12 of the calling side VoIP terminal 401.

On the transfer selection screen, a transfer destination list 62 as a transfer destination, a check box 61 for selecting a transfer destination, a response message content 63, a send button 64, a cancel button 65, and an answering machine button 66 are displayed. In the forwarding destination list 62, the upper power is also displayed in the descending order of the priority of the forwarding destination to which the VoIP terminal power on the called side is transmitted. The response message content 63 displays the response message sent from the called party.

[0050] When the caller selects the registrant name and presses the call button 64, the call is transferred to the selected transfer destination. The caller may send a message message by pressing the answering button 66, or may disconnect by pressing the cancel button 65. [0051] An example of the second response method table 22 will be described with reference to FIG. The second response method table 22 consists of an urgency level and a corresponding response method. For example, flags A, B, C, and D are used in order of urgency. The called party registers the response method according to the importance Z urgency from the input unit 13. In this example, emergency level A is incoming, emergency level B is forwarding, emergency level C is referring to the first response method table 21, and emergency level D is sending a standard response message. It may be set to receive incoming calls when rank B or higher and send a standard response message when rank C or lower.

[0052] The calling party sets an urgency level from the input unit 13 at the time of making a call, and transmits an urgency level flag together with other data to the called party. The incoming call side automatic response switching unit 112 extracts the urgency flag from the received data, extracts the response method with reference to the second response method table. Processing is performed according to the extracted response method. For example, when the urgency level is A, the incoming call processing is performed. When the urgency level is B, the transfer processing is performed with reference to the second schedule table.

Next, a method of registering the moved location information in the database 20 as destination information when moving to a network segment with a different VoIP terminal capability will be described. When a VoIP terminal moves to a different network segment, it is assigned a new IP address. Newly, the network address power of the IP address The current position of the VoIP terminal can be obtained. The VoIP terminal updates the destination data on the second schedule table 24 by sending the current position information to the database 20 again. In general, in IPv4 (Internet Protocol Version 4), when the IP address is set manually, the user does not know which network segment the current position is in or has moved to a different network segment. Therefore, the user transmits information on the current position to the database 20 at predetermined time intervals. If it is set to obtain an IP address automatically, a new IP address is distributed when the network segment is moved. Therefore, the user can know that the user has moved to a different network segment. Therefore, the current position information is transmitted to the database 20 when the movement is detected. In IPv6 (Internet Protocol Version 6), an IP address can be automatically acquired. Therefore, the current location information is sent to the database 20 by the latter method. As a result, the current location of the user Registered as a destination on the second schedule table 24.

Next, a route information guidance system using a mobile device and a communication base station according to the second embodiment of the present invention will be described with reference to the drawings.

FIG. 9 is a diagram showing a configuration example of a route guidance system according to the present invention. As shown in FIG. 9, the route guidance system according to the present embodiment includes portable devices 601a to 601c, a plurality of communication base stations 602a to 602c, and networks 603a to 603 in relation to a station. ing. Mobile devices 6 01a to c are small portable devices such as PDAs or notebook PCs that can be carried by users. In addition to general information processing functions, short-range wireless communication is possible with communication base stations. Wireless communication function (for example, wireless LAN function) is provided, and it is possible to connect to the WAN etc. via this wireless communication function.

[0056] As the short-range communication function used in the present embodiment, for example, a wireless LAN such as IEEE802.11b is used. IEEE802.11b is a wireless interface that uses the 2.4 GHz IMS (Industrial Scientific Medical) band carrier frequency, and between each device and AP (base station) over a communication range of about tens to hundreds of meters. : Access Point), and mobile devices 601a to 601c can be connected to the Internet via this wireless interface. There are no restrictions on the type of wireless interface that can be connected to the Internet using an IP address.

[0057] The communication base stations 602a to 602c are devices corresponding to the above-described wireless interface, and are configured by a base station AP and a router and the like, and have a function of wirelessly connecting to a portable device, and are assigned to each. Assign an IP address including the network address to the mobile device. These communication base stations are installed in premises such as stations and public spaces as shown in Fig. 9 and also in mobile transportation facilities such as trains as shown in Fig. 10. .

First, the route information guidance system according to the present embodiment will be described. When using this route information guidance system, first use the route search application software on the mobile device 701d to specify the starting point and destination, search the route, and obtain the obtained route. The guide information is stored in, for example, a database of the portable device 701d. Application software for route search is installed in the mobile device 701d. It is common in that only the route guidance information that is the search result is stored in the portable device 701d. The user carries the portable device 701d and moves to the destination according to the route information.

[0059] As shown in Fig. 13, the route guidance information includes route information using various means of transportation such as walking and trains, and includes information including the waypoint from the departure point to the destination. ing. Communication base stations are installed at each waypoint, and IP addresses are allocated from each communication base station to mobile terminals. Each waypoint can be connected to the Internet and can provide various services via the Internet. For example, at a hot spot in a station, a message to instruct you to get off at the next station if the next station is a stop station is displayed, or if the next station is a stop station Can perform services. Also, when a communication base station is installed in a train, it is possible to provide services such as outputting a message prompting to get off just before the getting off station.

The user activates the route search software in the route guidance control unit 821 by a predetermined operation, and inputs the departure point and the destination using the input unit 825. When the starting point / destination is input, the route guidance software outputs route guidance information 828 including the route from the input starting point to the destination. The route guidance information 828 is described here with reference to FIG. 13 as an example of using only a train as a transportation facility. To do. The route guidance control unit 821 determines whether or not the communication base stations 602a to 602c have been installed in the route guidance information 828 as locations to be set as transit points, based on the location information of the database 605 on the network. By checking with reference to the table 604, the communication base station 60

Set the waypoint according to the installation location of 2.

[0080] Also, if the communication base stations 602a to 602c are not installed at the transit point that will be the transfer station

If the information is registered as guidance information and the passing station in front of the transfer station is set as a waypoint, the guidance information at the waypoint is “Next is the stop station. It is also possible to call the user's attention by registering “Communication base station installed! In addition, every time the mobile terminal 601 establishes an Internet connection with the communication base station 602, the mobile station 601 collates the next location information in the route information immediately before the current route location in the route guidance information 828 with the current position information. Confirm that you are moving along the correct route.

[0081] As a different example of the above case, if there is no communication base station at the waypoint, the current position by the Internet connection cannot be confirmed, but the position information acquisition unit ₈₂₂ It is also possible to supplement the means for confirming the current position by using the position information obtained by proximity communication and the position information obtained by GPS.

[0082] If the collation results match, the next communication base station 602a-c and the location information obtained when the Internet connection is established are used to verify the next of the transit point corresponding to the current location. Set the waypoint information as collation information, and output a message such as “This is the correct route. If the result of the check is inconsistent, a message such as “The route is incorrect, will be searched again” is output, and the route guidance information 828 is searched again using the current position as the departure point.

[0083] As described above, in the system according to the present embodiment, the current position can be confirmed each time an Internet connection between mobile terminal 601 and communication base station 602 is established. If it is wrong, the new route guidance information 828 is searched again from that point as the departure point, and if it is correct, guidance to the next waypoint is notified. The

[0084] Next, as for an example in which the communication base station 702d is installed in the mobile transportation facility, only a portion different from the above example will be described. In other words, specify the route of departure and destination The portion up to the destination according to the route guidance information 828 obtained after the search is the same as the case where the communication base station 702d is not installed in the above-mentioned mobile transportation system. If communication base station 702d is installed in mobile transportation, it is always possible to establish an Internet connection in mobile transportation, so the location information of communication base station 702d is By updating to the table 604, the mobile terminal 701 can acquire position information for each update interval. Therefore, even when the communication base station 602 is not installed at the transit station serving as a transit point, it is possible to output a transit guidance message. Whether or not the communication base station 702d is installed in the mobile transportation facility can be confirmed by referring to the fixed 'movement flag registered in the information table 604, and the information is obtained at the time of route search. Stored as route guidance information 828.

[0085] In addition, by establishing an Internet connection with the communication base station 602 at each waypoint, provision of a transfer MAP within the station premises at the transfer station, and additional information services such as the availability of lunch boxes at the store Can be provided. If the communication base station 702d is installed in a mobile transportation facility such as a train, it is possible to provide services such as VoIP on the train, but the manner mode set for the mobile devices 601a-c It is also possible to automatically switch usage permission of applications installed in the mobile devices 601a to 601c in cooperation with the position information acquired by setting.
