Description

The method and system of reporting position information
Technical field
The present invention relates to the communications field, particularly a kind of method and system of reporting position information.
Background technology
WiMAX (Worldwide Interoperability for Microwave Access, the inserting of microwave of global-intercommunication) be one based on broadband wireless access metropolitan area network technology, its elementary object is the broadband wireless access means that a kind of interoperability effectively a bit is provided under the multivendor environment to multiple spot at metropolitan area network.The mobility and flexibility of WiFi wireless access technology that WiMAX is integrated and xDSL etc. are based on the high bandwidth characteristic of traditional broadband access technology of cable, have cover wide, insert advantages such as fast.
The WiMAX network standard provides a cover than more comprehensive processing procedure, inserts the Internet or carries out intercommunication with other MS (Mobile Station, mobile subscriber station are called portable terminal again, or terminal) by WiMAX to guarantee terminal.MS has two states: connection mode and idle pulley after inserting WiMAX.Generally speaking, when MS when carrying out session service, need remain on connection mode, so that network provides related service (except some particular service); When MS no longer sends the reception business in a period of time, will enter into idle pulley, this process can be initiated by MS or network.
For the MS of idle pulley, professional if MS wants to initiate, then need to exit from idle mode, enter connection mode from idle pulley; When perhaps network had the business relevant with MS to arrive, then ASN (Access Service Network, access business network) needed paging MS, makes MS enter connection mode from idle pulley.Referring to Fig. 1, the detailed process of paging is as follows:
1) Anchor DPF (Anchor Data Path Function, anchor point data path functions equipment)/the relevant downlink data of FA (Paging Agent, paging agent) reception MS, for example, downlink data can be sended over by HA (Home Agent, home agent);
2) Anchor DPF/FA finds that MS is in idle pulley, then initiates initial paging request to Anchor PC (Anchor Paging Controller, anchor point paging controller)/LR (Location Regester, location register);
3) after Anchor PC/LR receives initial paging request, return initial page response to Anchor DPF/FA;
4) Anchor PC/LR initiates paging, Anchor PC/LR produces one or more paging notice messages (Paging_Announce) and carries out paging, wherein transmit by one or more relay PC, or directly send the paging notice message to coupled BS (Base Station, base station);
5) relay PC is transmitted the paging notice message to BS, and BS receives paging MS behind the paging notice message; After perhaps the PA on the BS (Paging Agent, paging agent) receives the paging notice message, convert the broadcast of eating dishes without rice or wine (MOB-PAG_ADV) to, paging MS;
6) after MS receives beep-page message, initiate idle pulley and withdraw from or the position refresh routine, enter into connection mode, and receive the data of other functional entity in the ASN network.
Referring to Fig. 2, comprise the functional entity that three location-based services are relevant in the existing location-based service structure:
LS (Location Server, location server) is positioned at CSN (Connectivity Service Network, connect business network), it provides the outside or inner authorized entity of device location to network, based on external request, is responsible for initiating the location-based service process.For the active position service, it is to AAA (Authentication, Authorization and Accounting, authentication, mandate and charging) server transmission position data, request authentication (Location Data Request Authenticate), if the aaa server authentication is passed through, aaa server will provide equipment mark AA (Anchor Authentocator, anchor point authentication) to give LS.LS can know the LC sign of equipment correspondence, and then LS can carry out the follow-up location session by AA.
LC (Location Controller, positioner) is positioned at the ASN network, and it is responsible for obtaining the positional information of the equipment of LS request.LC can use several different methods to come the position of positioning equipment, and when using based on network method, LC is responsible for the base station that Mediation Device connects, and determines the position or the location parameter of equipment.LC provides the position of terminal or location parameter to LS.It also can be according to request, gives other built-in functions in equipment self or the ASN network with these information, as RRM, mobile management function etc.
LA (Location Agent, location agent) is arranged in BS or MS, is responsible for measurement or collection alternatively, reported position related data to LC.If LA is arranged in MS, it will communicate with corresponding LA among the BS.
Prior art provides a kind of MS to initiate the method for location-based service, and referring to Fig. 3, this method detailed process is as follows:
1) LS receives LDR (the Location Data Request that external client sends, position data request) after the message, disposable or periodically obtain the location service information of MS, comprise DR (Desired Resolution in the above-mentioned LDR message, the resolution of expectation), Periodicity (cycle), Latency (reaction time) and Duration parameter informations such as (duration).
2) LS sends a request message to AAA, and request AAA checking external client is to the legitimacy of the position requests of MS.
3) after AAA receives the request message of LS, the position requests and the MS of external client verified.
Because it is distinctive signatory that MS need be authorized to guarantee it, and the external client of initiating position requests must be authorized, after so AAA receives the request message of LS, position requests and MS to external client verifies according to user's configuration (user profile), user's configuration comprises position location capability and the secure option of MS, for example, GPS (Global PositionSystem, global positioning function), support WiMAX stationkeeping ability that strengthens and the location-based service (rank/type) of contracting etc.
4) after the AAA checking is passed through, return response message to LS.
5) after LS receives the response message that AAA returns, obtain the LC sign at MS place to the ASN network.
It is relevant which kind of state the process that LS obtains LC sign and MS are in, and when MS was in connection mode, it is as follows that LS obtains the detailed process that LC identifies: LS sent a request message to AAA, obtains the sign of MS place anchor point authentication function; After AAA receives the request message that obtains anchor point authentication function sign of LS transmission, return the response message that carries anchor point authentication function sign to LS; After LS receives the response message that AAA returns, send a request message to the anchor point authentication function, to obtain the LC sign at MS place according to the sign of the anchor point authentication function in this message; After the anchor point authentication function is received the request message of LS transmission, return the response message of the LC sign of carrying the MS place to LS.
When MS was in idle pulley, the detailed process of LC sign that LS obtains the MS place is as follows: LS sent a request message to AAA, obtains the sign of MS place anchor point authentication function; After AAA receives the request message that obtains anchor point authentication function sign that LS sends, return to LS and to carry anchor point authentication function identification response message; After LS receives the response message that AAA returns, send a request message to the anchor point authentication function, to obtain the LC sign at MS place according to the sign of the anchor point authentication function in this message; The anchor point authentication function is returned acknowledge message to LS after receiving the request message of LS transmission, and instruct MS is in idle pulley; The anchor point authentication function triggers anchor point paging controlled function paging MS; MS is paged arrive after, MS exits from idle mode under the ASN of current connection; After MS exitted from idle mode, the anchor point authentication function was returned response message to LS, and this response message carries the LC sign after the renewal.
6) after LS gets access to the sign of LC, initiate the position message request message, the location positioning procedure of beginning MS to this LC.Comprise the positional information that LS wishes the MS that obtains in request message, some information in this positional information are about MS user or equipment, for example, and ID (sign) and SLC (Special Location Capability, ad-hoc location ability) etc.
7) above-mentioned LC carries out location estimation, obtains the positional information of MS.
8) after LC gets access to the positional information of MS, to LS home position report response message.
Wherein, what LC obtained can be the MS sign, the position respond style, position data and resolution or credit grade position parameter informations such as (Resolution/Confidence Level), also can be the positional information of MS, so in the position message response message, carry the positional information of position parameter data or MS.
If position session is periodic, then the 6th) LS sends a request message to LC in the step, and request LC regularly reports the positional information of MS; After LC receives this request message, regularly report the positional information of MS to LS.
9) after LS receives the position message response message that LC returns, to external client home position data response message.
If what carry in the position message response message that LC returns is position parameter data, then LS need calculate according to position parameter data again, obtains the positional information of MS, and returns to external client with the form of request; In addition, if LC periodically reports response message to the LS home position, then LS also periodically reports the positional information of MS to external client.
LS can also initiate to charge and upgrade to AS (Acounting Server, accounting server).
In realizing process of the present invention, the inventor finds to exist at least in the prior art following shortcoming:
After MS sets up one-period location-based service session, if MS enters into idle pulley, the LC of the original position of MS will delete the logic function relevant with MS, thereby this LC can't relocate MS, cause the periodic location service conversation of MS to be interrupted.

Embodiment 2
Present embodiment provides a kind of method of reporting position information, comprising:
When setting up periodic location service conversation and terminal when connection mode enters idle pulley, terminal is obtained the position session contextual information;
Behind terminal access idle mode, terminal triggers the positioner at current location place and determines location information of terminals, and this positional information is the positional information relevant with the position session contextual information;
Positioner reports location server with positional information.
In the present embodiment, to set up relevant periodic location service conversation of MS and MS on MS and the network when connection mode enters idle pulley, the position session contextual information that is obtained MS by MS is that example describes, referring to Fig. 6, the embodiment of the invention also provides a kind of method of reporting position information, specifically may further comprise the steps:
Step 201: set up relevant periodic location service conversation of MS and MS when connection mode enters idle pulley on MS and network, MS obtains all or part position session contextual information of MS from current LC.
When connection mode entered idle pulley, LC sent the position session contextual information by BS to MS at MS; Simultaneously, (for example need an anchor point logical functional entity in the ASN network, AA) the position session contextual information of preservation MS, if set up in the process at the periodic location service conversation, AA does not preserve the position session contextual information of MS, then enters the periodic location session context information of preserving MS in the process of idle pulley (obtain as the LC from MS current location place etc.) at MS.
Step 202:MS sends range finding (RNG_REQ) message every the session cycle to BS, and the LC that triggers MS current location place determines the positional information of MS, and this positional information is the positional information relevant with the position session contextual information, and the line position of going forward side by side reports.
Carry the relevant indication information of location-based service session in the above-mentioned range finding message, this indication information also can be carried in other message, or is defined in separately in the message.
After step 203:BS receives the range finding message that MS sends, send the location-based service Indication message to LC according to the relevant indication information of the location-based service session in the range finding message.
Above-mentioned location-based service Indication message also can be used as a parameter in the existing message, for example, this location-based service Indication message is included in the location update message, sends to the gateway at local relay PC place by location update message.
After step 204:LC receives the location-based service Indication message, when not having the position session contextual information of MS on the LC, obtain the position session contextual information of MS.
Wherein, it is specific as follows that LC obtains the process of position session contextual information of MS:
LC sends a request message to anchor point PC;
Anchor point PC transmits this request message to AA after receiving the request message of LC to MS;
AA verifies after receiving the request message of anchor point PC transmission that after checking was passed through, PC returned response message to anchor point, carries the relevant position session contextual information of MS in this response message, for example, and information such as LS sign;
After anchor point PC received the response message of AA transmission, the gateway to the LC place returned the response message that carries the relevant position session contextual information of MS.
In said process, LC also can directly send the message of acquisition request position session contextual information to AA, after AA receives this message, the position session contextual information is returned to LC.
Step 205:LC determines the positional information relevant with the position session contextual information of MS.
Step 206:LC sends the reporting position message of the positional information carry MS to LS, and the positional information of MS is reported LS.
After step 207:LS confirms the positional information of the MS that LC reports, to LC home position acknowledge message.
After step 208:LC receives the location confirmation message that LS returns, to BS home position service indication response message.
Step 209:BS sends ranging response (RNG_RSP) message to MS after receiving the location-based service indication response message that LC returns.
Referring to Fig. 7, going up the position session contextual information of preserving MS with AA below is the detailed process that MS enters idle pulley in the example description of step 201:
G1.MS sends to the BS at PA place and enters idle-mode request message (DREG_REQ), and expression MS wants to enter idle pulley.
After the BS at g2.PA place receives that the state of MS changes request message, obtain the position session contextual information of MS, for example, the session cycle etc., and to MS transmission position session contextual information, BS changes request (IM_Entry_State_Change_Req) message to the relay PC transmit status of MS position.
G3. after relay PC received that the state of BS transmission changes request message, the gateway transmit status to anchor point PC place changed request message.
G4. after anchor point PC receives that the state of relay PC transmission changes request message, change request message (IM_Entry_State_Change_Req), whether allow MS to enter idle pulley with checking to AA place gateway transmit status.
After the g5.AA checking is passed through, the sign of storage anchor point PC, and to anchor point PC return state change response (IM_Entry_State_Change_Rsp) message.
In the present embodiment, with anchor point PC and AA be respectively two independently physical entity be that example describes, further, when anchor point PC and AA coexistence, then step g 6 is omissible.
AA can also send to MS with the periodic location session context information of the MS that preserves by following dual mode:
AA is with the position session contextual information, and for example location-based service conversation type, session cycle etc. is carried in the above-mentioned state change response message and sends to anchor point PC;
Perhaps, when local relay PC was also preserved the position session contextual information of MS, AA sent Indication message to the gateway at local relay PC place, after the gateway at local relay PC place is received Indication message, the position session contextual information is sent to MS.
