Fig. 4 is used to illustrate when the LBS application program 303 of travelling carriage 101 inside obtains correct mandate, the schematic diagram of pass-along message sequence between each assembly of the system 100 that realizes disclosed method and apparatus.Each assembly of each box indicating shown in Fig. 4 top.These assemblies comprise LBS application program 303, engine of positioning 305, PDE 107, reach MPC 105.Represent the passing of time from each assembly 303,305,107, vertical line 401a, the 401b of 105s, 401c, 401d.On the line apart from nearest point on the nearest each point express time of assembly 303,305,107,105.
Beginning, LBS application program 303 is called engine of positioning 305.Point to arrow 403 these steps of expression of engine of positioning 305 from LBS application program 303.In a particular embodiment, engine of positioning 305 is gpsOne
TMApplication programming interfaces (API).Should be noted that in some embodiment of current disclosed method and apparatus, can notify user of mobile station LBS application program just attempting operation.Some this class embodiment require the user to confirm that this user wishes to carry out the function that the LBS application program will be carried out.If carry out this class notice and affirmation, then will be in the LBS application program to gpsOne
TMPreferably exercise notice and affirmation before the API Calls.
In response to the calling of engine of positioning 305, engine of positioning 305 sends Location Requests to the MPC 105 that uses predetermined travelling carriage/MPC (MS-MPC) agreement.According to the MS-MPC agreement, travelling carriage 101 starts a TCP/IP session with MPC 105.Communicating by letter between the arrow 405 expression travelling carriages 101 shown in Fig. 4 and the MPC 105.From the TCP/IP session of travelling carriage 101 to MPC105 is to be based upon on the virtual ip address of operator's appointment and the port numbers.In a single day the TCP/IP session sets up, and MS just will send " StartPositioningProcessRequest " (" request of beginning localization process ") message to MPC 105.This message will comprise many parameters.
In an embodiment of current disclosed method and apparatus, these parameters comprise content provider's resource locator (URL).The content provider is being an entity that is positioned at cordless communication network 103 outsides in typical case.The content provider provides the specific LBS application program 303 needed information in the travelling carriage of just attempting to move 101.For example, if this application program is just attempting to seek nearest restaurant, then the content provider will be the database about restaurant and positional information thereof.Can visit the content provider by Internet Protocol (IP) address, this IP address can obtain from the URL that is provided.
In an embodiment of current disclosed method and apparatus, be sent to MPC 105 " each parameter of beginning localization process request information also comprises application indicator.This application indicator indicate which specific LBS application program just attempting the operation.Whether another parametric representation user agrees to allow LBS application program 303 move on travelling carriage 101.Also having the another one parameter is mobile station identification value (MS ID).MS ID represents LBS application program 303 will be moved on which travelling carriage 101.
Also has a parametric representation MS stationkeeping ability in addition.Because each travelling carriage 101 handles and the ability of handle position location information may have nothing in common with each other, so this parameter list has illustrated the ability of travelling carriage 101.For example, the knowledge that perhaps specific travelling carriage 101 is merely able to based on about which sector of which sub-district in the cellular phone network (being the base station) or a sub-district just communicating by letter with this travelling carriage 101 is this moment carried out location Calculation.Other travelling carriage perhaps can only assistant base station 103 positions of calculating these travelling carriages.It has been generally acknowledged that this travelling carriage only moves in auxiliary the mixing under (MS-assisted hybrid) pattern of MS.Perhaps, other travelling carriage can either help the base station to calculate this location of mobile station, can calculate the position of this travelling carriage again in travelling carriage independently.It has been generally acknowledged that the auxiliary mixed running pattern of the existing MS of this travelling carriage has the GPS operational mode based on MS again.Further, some travelling carriages do not have stationkeeping ability at all.
The example of another parameter is a cell/sector information.It is to carry out the cell/section location separately that cell/sector information allows MPC to select, and execution still combines with the GPS location.Other parameter that also provides some and disclosed method and apparatus to have nothing to do in the beginning localization process solicited message.
Response beginning localization process solicited message 405, MPC carries out authorisation step can visit the location application of being asked to guarantee this specific user.Whether in addition, MPC checks needs engine of positioning 305 to judge the position at travelling carriage 101 places.That is to say, can use buffer memory (that is, precalculated, storage, the also still effective) position of travelling carriage 101 recomputating the position of travelling carriage 101 in some cases.In other cases, with utilize only know just with cellular communications networks that travelling carriage 101 is communicated by letter in the position of particular cell/sector, so that LBS application program 303 sufficiently high precision are come positioning mobile station 101.
Engine of positioning 305 in judging travelling carriage 101 need position when calculating, and MPC105 makes response to engine of positioning 305.MPC judges whether the LBS application program 303 in the travelling carriage 101 has the proper authorization of calculating these travelling carriage 101 positions, and MPC 105 makes response according to this judged result.MPC 105 judges whether LBS application program 303 has the suitable power of operation.Perhaps because the user refuses these travelling carriage 101 positions of LBS application computes, perhaps because MPC 105 judges information about LBS application program 303 to be not enough to fully to the LBS application program is moved, MPC 105 can determine that the LBS application program do not move power.This may be because the user does not also pay the required expense of LBS application access LBS service or imperfect about user's information that allows.No matter whether the LBS application program has the power of operation, MPC 105 sends " beginning localization process a request information 407 to travelling carriage 101.Will illustrate in greater detail below, according to the content of beginning localization process request message 407, engine of positioning 305 or photograph indication are removed to carry out GPS " session " or are not carried out.Fig. 5 has illustrated at MPC and has judged the message sequence that LBS application program 303 does not obtain moving under the authorization conditions.In order to say earlier in the text that is right after below that the LBS application program obtains moving the complete sequence when authorizing, the concrete condition of this sequence of Fig. 5 will be postponed till more following.
The GPS session comprises: 1) catch and calculate the necessary satellite in travelling carriage 101 positions, 2) the demodulation of satellite navigation message, and 3) calculate location of mobile station based on the available GPS information of travelling carriage 101.
According to current disclosed method and apparatus, beginning localization process request message comprises following information:
1) version number, expression is used to make up the version of the standard that begins the localization process request message;
2) length of beginning localization process request message;
3) positioning states message, the used method of location of mobile station is calculated in expression.According to current disclosed method and apparatus, employed parametric representation in this message: a) whether engine of positioning will use GPS, b) positional information of buffer memory, c) cell/sector information, d) whether the user has refused to allow the request of LBS application computes travelling carriage 101 positions; Perhaps e) without permission whether this ask;
4) position of will use GPS to calculate travelling carriage 101 is supposed in PDE IP address;
5) PDE port numbers is used for sensor interface application program (SIA) (not shown), and SIA and PDE 107 synthetic operations communicate to help PDE 107 and other assembly away from PDE 107;
6) value is used for representing beginning whether to comprise in the localization process request message estimation to travelling carriage 101 sites; And
7) time mark, expression and the relevant gps time of travelling carriage 101 location estimation;
8) latitude of travelling carriage 101 sites is estimated that it is provided with the form of telecommunications industry association/electronic industries association (TIA/EIA) standard I S-801-1 title for the standard one joint defined of " the position response message is provided ";

13) Height Estimation is provided with the form of TIA/EIA standard I S-801-1 title for the standard one joint defined of " the position response message is provided ".
In case after judging that the LBS application program is authorized to, MPC 105 also sends " GPOSREQ " message 409 to PDE 107 except send beginning localization process request message 407 to travelling carriage 101.The GPOSREQ message 409 that is dealt into PDE 107 is for PDE107 provides information, and auxiliary PDE 107 colocated engine 3s 05 are worked, and judge the position of travelling carriage 101.Especially, GPOSREQ message 409 provides about just and the positional information of the base station 104 that communicates of travelling carriage 101 for PDE 107.This information makes PDE 107 position of travelling carriage 101 can be determined in several miles or littler scope.PDE 107 information of just can offering help to maximal efficiency like this, the engine of positioning 305 with in the auxiliary moving platform 101 with which satellite of easier judgement is visible and catches those satellites more quickly.
Engine of positioning 305 except sending beginning localization process request message 405, also attempts to carry out the location sessions 411 of a Mobile Origination (MO), and this session is according to listed agreement among the TIA/EIA standard I S-801.But, having only when PDE 107 receives GPOSREQ message 409, PDE 107 just responds the information request of sending from the engine of positioning 305 in the travelling carriage 101.This will more specifically set forth in to the argumentation of Fig. 5.MO IS-180 session had both comprised the message that is dealt into engine of positioning 305 from PDE 107, also comprised the message that is dealt into PDE 107 from engine of positioning 305.Last in MO IS-180 session supposed the session normal termination, PDE 107 send message 413 to MPC 105 with the notice normal termination.At last, the engine of positioning 305 in the travelling carriage 101 sends message 415 to LBS application program 303, contains the position of travelling carriage 101 in this message.
Fig. 5 is used to illustrate when the application program of travelling carriage inside does not obtain appropriate mandate the schematic diagram of pass-along message sequence between LBS application program 303, engine of positioning 305, PDE 107 and MPC 105.The beginning of process shown in Figure 5 is the same with process shown in Figure 4.That is to say that LBS application program 303 is at first called engine of positioning 305, shown in the arrow among Fig. 5 403.Engine of positioning 305 generates a beginning localization process request message 405 then, and message 405 is sent to MPC 105.But in the situation shown in Figure 5, MPC 105 has refused the trial of the positioning service of LBS application access PDE 107.Therefore, MPC 105 returns to 305 1 beginnings of the engine of positioning localization process request message 501 in the travelling carriage 101, notifies the request of its visit PDE 107 to be rejected.Because request according to the LBS application program, engine of positioning 305 is not judged enough sufficient information that travelling carriage 101 positions are required, so engine of positioning 305 returns a message 503 to LBS application program 303 in response, the request of the service of its visit of this message informing PDE 107 is rejected.At this moment, process finishes, and LBS application program 303 is out of service immediately because travelling carriage 101 receives about the failure of travelling carriage 101 positional informations.In an alternative embodiment, LBS application program 303 can continue operation, but the positioning service that can not use PDE 107 to provide.
