In order to make those skilled in the art understand better technical scheme among the present invention, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is described in detail, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills obtain should belong to the scope of protection of the invention.
Figure 1 shows that the flow chart of a kind of mobile terminal locating method that the embodiment of the invention provides, the method can may further comprise the steps:
S101 obtains near the identification information of the base station the portable terminal to be positioned;
According to the scheme that the embodiment of the invention provides, near the base station identification information of server side can active obtaining portable terminal to be positioned realizes the location to this portable terminal.Portable terminal to be positioned also can send Location Request to server side, and in this Location Request, carries near himself base station identification information.
For the portable terminal with access to mobile network function, can scan its one or more base station signal sources on every side, and get access to the sign of these base stations, for example basic station number.Further these base station identification information are uploaded to server side, server side just can position portable terminal according to base station identification information.
In actual applications, portable terminal may scan a plurality of base station informations source in same place, this moment the portable terminal side that the sign of a plurality of base stations all can be uploaded onto the server, also can be only with the sign of the current access base station side that uploads onto the server.
S102, according to base station identification information, the base station position information that inquiry is corresponding;
In this step, the base station identification information that server side reports according to portable terminal to be positioned is inquired about the base station position information corresponding with base station identification information.
Theoretically, for any base station, can manage to collect in advance the positional information of this base station, and set up the database of " base station identification information-base station position information ".Consider in the practical application that the quantity of base station is more and dispersion is wider, is the collecting efficiency that improves base station position information, the invention provides a kind of automatic acquiring method of base station position information, the method is as follows:
In actual applications, there are a lot of portable terminals itself to possess other stationkeeping abilities, such as architecture ability of GPS stationkeeping ability, Wifi stationkeeping ability or movement-based carrier network etc., in order to distinguish architecture scheme provided by the present invention, in the present embodiment, this class stationkeeping ability is called " the second stationkeeping ability ", the positional information of utilizing the second stationkeeping ability to obtain is called " second place information ".If this Terminal Type has again the ability of access mobile operator network simultaneously, so, this class portable terminal just can when scanning base station identification information, utilize the second stationkeeping ability to know self current residing position.Portable terminal can report to server side with base station identification information and the current residing positional information that scans, and like this, server side just can obtain the corresponding relation of a large amount of " near the Base Station Identification mobile terminal locations-portable terminal ".
Further, it is related that the second place information that server side can report same portable terminal and base station identification information are carried out, and that is to say, with the approximate position of thinking near the base station this portable terminal, the current residing position of portable terminal.In general, under the positioning accuracy demand is not very high situation, this approximate be acceptable.Certainly, the prerequisite of doing like this is that portable terminal " the second stationkeeping ability " can be located comparatively accurately, therefore, here " the second stationkeeping ability " is preferably the GPS stationkeeping ability, certainly, in the situation that can guarantee certain positioning accuracy, " the second stationkeeping ability " also can be other locate modes, and the embodiment of the invention does not need this strictly to limit.
Illustrate, shown in Fig. 2 a, mobile terminal UE 1 with GPS stationkeeping ability, has a base station BS 1 around current can the scanning, UE1 can be known the positional information L1 that self is current by GPS simultaneously, so UE1 can report to server side with L1 and BS1 (supposing that BS1 is the identification information of access point), server side can associate L1 and BS1 correspondence, that is to say, L1 is similar to thinks the positional information of BS1 and store this corresponding relation:
| Access point | The position |
| BS1 | L1 |
Table 1
If portable terminal can scan a plurality of access points simultaneously at same position, then server side can be confirmed as same position the position of a plurality of access points, shown in Fig. 2 b, current can the scanning of UE1 has three access point BS2, BS3, BS4 on every side, UE2 can be known the positional information L2 that self is current by GPS simultaneously, so UE1 can report to server side with L2 and BS2, BS3, BS4, server side can associate L2 and BS2, BS3, BS4 correspondence, and the corresponding relation of concrete storage is as follows:
| Access point | The position |
| BS2 | L2 |
| BS3 | L2 |
| BS4 | L2 |
Table 2
Because the present invention program adopts the mode of approximate storage BS positional information, therefore in actual applications, a kind of situation that may run into is: the BS identification information that terminal is uploaded is identical, but positional information is different, the situation shown in Fig. 2 c for example, UE3 and UE4 can scan BS5 respectively, but these two terminal present position L3 and L4 and inconsistent.In addition, L3 and L4 also may be that same terminal is at the residing diverse location in mobile front and back.For this situation, in this step, server side when actual treatment, can integrate processing to a plurality of positional informations after, obtain a unique position, store again, for example:
| Access point | The position |
| BS5 | F(L3，L4) |
Table 3
Wherein, F (L3, L4) expression is processed function to the integration of a plurality of positional informations, the focus point of for example getting a plurality of location points is as the location point after integrating: the coordinate of supposing L3 is (x3, y3), the coordinate of L4 is (x4, y4), F (L3 then, L4) coordinate is [(x3+x4)/2, (y3+y4)/2]; Also can select to arrive a plurality of location points apart from the point of sum minimum as the location point after integrating.The present invention does not need to limit to concrete integration algorithm.
The below carries out simple declaration to the specific implementation of getting minimum range and point:
At first, for a plurality of base station location point L1, L2, L3......, select any one location point as initial point, then get an increment size Δ at random,
On initial point, beginning is attempted expanding toward the four direction in space according to the increment size Δ successively, if less with value to all location points of the point of attempting then moves to reposition to this point.Otherwise changing a direction attempts.
If four direction is all irremovable, then reduce the increment size Δ, get 0.5 times or 0.618 times, again attempt.
When the increment size Δ is enough little, when reaching required precision, then withdraw from this time circulation, obtain final integration location point.
The above-mentioned method of choosing minimum range and point can be understood as: at first at will get a base station location point, look at this point to the distance of other each base station location points and what are, again this point is once looked at whether have more suitably mobile all around.Have more suitably and just replace, more suitably just do not dwindle moving range, until find only that point.
Being understandable that in actual applications, portable terminal to be positioned may report the identification information of one or more base stations, in the data of storage, is to allow to occur " the corresponding same base of different Base Station Identifications address " this situation therefore.Certainly, on macroscopic view, the reported data that server side is received is more, and the base station location of finally integrating out will more level off to the true geographical position of base station, and so above-mentioned situation also just can correspondingly be avoided.
By above-mentioned base station position information acquisition method, again in conjunction with some artificial collection typings, can form the corresponding relation database of a base station identification information and base station position information.After mobile terminal reporting base station identification information to be positioned, just can according to the base station identification information that reports, inquire corresponding base station position information.
S103 according to the base station position information that inquires, determines the position of described portable terminal to be positioned.
At first need to prove, in order to realize the location to terminal, should guarantee in the Query Result of S102, at least comprise a base station position information, if a result does not inquire, illustrate that server side does not collect the positional information of this portable terminal peripheral base station to be positioned in advance, can't proceed the location this moment.
The below will describe in detail: in Query Result, comprises in the situation of one or more base station position informations, for the targeting scheme of terminal:
The simplest a kind of situation is: (concrete reason may be that portable terminal has only reported a base station identification information at S101 only to inquire a base station position information in S102, also may be that portable terminal has reported a plurality of base station identification information at S101, but in S102, only find the positional information of a correspondence).For this situation, can be directly be the position of portable terminal to be positioned with the location positioning of this base station.
If in S102, inquire a plurality of base station position informations (owing in S102, adopted the storage mode of integrating, therefore upper these a plurality of base station informations are respectively a plurality of signs of reporting among the corresponding S101), so, need to be according to these a plurality of positional informations, integrate out a location point, as the positioning result of portable terminal to be positioned.
Wherein, the algorithm of integrating can be: get the focus point of a plurality of location points as the location point after integrating, also can be get reach a plurality of location points apart from the point of sum minimum as the location point after integrating, etc., the present invention does not need to limit to concrete integration algorithm.
Utilize said method, server side can be finished the location to portable terminal, according to the actual requirements, can also further positioning result be sent to portable terminal, with the Location Request of response portable terminal.Scheme provided by the present invention, by server side according near the Base Station Identification the current location of portable terminal, the base station position information that inquiry gathers in advance, thereby position, the current location of portable terminal is roughly calculated, although can't reach the positioning accuracy of GPS, but can not possess in the situation of other location conditions at portable terminal, solve the portable terminal orientation problem.
In addition, base station position information acquisition method provided by the present invention, so that non-moving Virtual network operator also can provide the positioning service based on the base station, in conjunction with in conjunction with services such as network maps, can give equally to allow the user that there is a understanding roughly self current residing position, have larger using value.
In actual applications, another problem that may run into is: because diversity and the lack of standard of customer mobile terminal may cause a plurality of true base stations physically to be mapped to identical Base Station Identification.For example, two base stations below:
Base station A:460; 00; 345; 235
Base station B:460; 01; 345; 235
Because some customer mobile terminals (for example " mountain vallage machine ") have adopted design lack of standardization, so, for this Terminal Type, the Base Station Identification that may scan the B of A all is " 0; 0; 345; 235 ", design lack of standardization may affect not quite normally using of this terminal itself in this, but in the present invention program, the actual meeting of positional information meeting that this Terminal Type reports makes a big impact to the accuracy of data.If the physical location of base station A is positioned at Beijing, the physical location of base station B is positioned at Shanghai, yet server side can be with " 0 after receiving a large amount of reported datas; 0; 345; 235 " final position is incorporated near the line central point in Beijing and Shanghai, causes two real base station positions of integrated results distance all far.
For above-mentioned situation, a solution provided by the present invention is: if server side has been received a plurality of reporting position informations for same Base Station Identification, so, before a plurality of positional informations are integrated, at first based on geographical distribution, a plurality of second place information are carried out cluster.
The general thought of clustering algorithm is based on distance and carries out cluster:
1) from the set B of having a few, select 1 point, consist of set A.Calculate the point in the A set, all the other beeline dis that have a few in the B are if dis is less than a certain threshold value.Then incorporate this point into set A.Then, continue the distance of all the other points of having a few among the set of computations A.Until minimum range dis is greater than a certain threshold value, thereby set A is consisted of a class.
2) in the remaining point, select 1 point from B, repeating step 1 is until the B set is for empty.
Referring to shown in Figure 3, use said method, can be with " 0; 0; 345; 235 " all corresponding location points gather into two classes according to its position.Then for resulting each cluster, integrate respectively and obtain a location point.That is to say, for Base Station Identification " 0; 0; 345; 235 ", the location point after two integration of meeting corresponding stored in database.
Correspondingly, in step S101, if a Base Station Identification of uploading according to the user has inquired a plurality of location points, illustrate that these a plurality of location points are the integrated results after the cluster, can all return a plurality of location points to the user this moment, allows the user judge voluntarily.In the distant situation in two position locations, it is feasible processing like this, for example, the user must know that own current is in Beijing or in Shanghai, therefore, return to the user and to return respectively one and be positioned at Pekinese's particular location and be positioned at the particular location in Shanghai, can satisfy user's location requirement.
In another embodiment of the invention, server side can also be according to user's historical movement track, for the user determines a positioning result automatically.Wherein, the historical movement track can be the result of n location (can be GPS location, architecture, wifi location etc.) before the customer mobile terminal, movement locus can S101 in portable terminal to be positioned near base station identification information obtain in the lump, also can when demand is arranged, obtain separately.Server side just can in a plurality of base station locations corresponding to same Base Station Identification, be selected the possibility extreme higher position as final positioning result according to the movement locus of portable terminal.
Corresponding to top embodiment of the method, the present invention also provides a kind of portable terminal positioner, and referring to shown in Figure 4, this device comprises:
