Description
Technical field
The present invention relates to the location technology of the network equipment, be meant the information interacting method of periodic location information request in a kind of location service especially.
Background technology
Location service (the LCS of mobile communications network, Location Service) is the positional information that obtains target UE (UE) by location technology, object UE refers to that the object UE terminal that is positioned in the mobile communications network, positional information can be the geographical latitude and longitude information or the positional information in local street.The positional information that the LCS system obtains can offer object UE, is used for self poisoning; Also can offer client's application end that other requests obtain the object UE positional information,, be used for value-added service as mechanism and individual.Therefore, location service all has effect widely at aspects such as emergency relief, automobile navigation and intelligent transportation system, scheduling and Team Management, mobile yellow pages inquiry, enhancing network performances.Aspects such as functional mode, structure, state description and message flow to the standard of LCS and whole LCS system in third generation partner program (3GPP) all are described.
Fig. 1 is a LCS cellular logic structural representation, as shown in Figure 1: from function logic, realize that the function logic entity of location service relates to request end 101, Gateway Mobile Location Center (GMLC) 102, storage of subscriber data server (HLR/HSS) 103, core network (CN) 104, Radio Access Network (RAN) 105 and object UE 107.Wherein, Gateway Mobile Location Center (GMLC) 102, storage of subscriber data server (HLR/HSS) 103, core network (CN) 104 and Radio Access Network (RAN) 105 have been formed LCS system 106.Request end 101 comprises requestor and LCS client.LCS client is meant the positional information that is used to obtain one or more object UE 107, with the software or the hardware entities of LCS system 106 interfaces; The requestor is meant the request applications client of request target UE 107 positional informations, as mechanism and individual, is the promoter of Location Request, and LCS client can be the requestor simultaneously also.GMLC 102 provides the LCS interface of a standard for the information interaction of 106 of request end and LCS systems, be responsible for request end 101 is carried out authentication and the location information request message that request end 101 sends is carried out authentication, the request that authentication positions object UE 107 to CN 104 initiations by the back, at last, GMLC 102 is responsible for the positional information of object UE 107 is sent to request end 101.GMLC 102 can further comprise request gateway Mobility Center (R-GMLC, RequestingGMLC), home gateway Mobility Center (H-GMLC, Home GMLC) and visit gateway Mobility Center (V-GMLC, Visited GMLC).R-GMLC is the GMLC in the request end request LCS network 106, and H-GMLC is that object UE 107 ownership LCS net the GMLC in each, and V-GMLC is the GMLC in the object UE 107 visit LCS networks, and R-GMLC, H-GMLC and V-GMLC can be same physical entity.HLR/HSS 103 is used for storaging user data, and for other cellular logic entities provide the relevant information of subscriber equipment, as H-GMLC, the V-GMLC of subscriber equipment and the address information of CN104.CN 104 receives and manages GMLC to object UE 107 location request initiating information, and collaborative 105 pairs of object UE 107 of RAN position, and send positioning result to GMLC.RAN 105 according to canonical algorithm, as CellID+TA algorithm, TOA algorithm, E-OTD algorithm etc., to calculating the position of object UE 107, and sends positioning results to CN 104 under the request of CN 104.
At present, the location information request of in the LCS standard of 3GPP the request end being initiated object UE is divided into two types: type location information request and delaying type position information request immediately.
After the type location information request is meant that the location information request of request end to the object UE initiation received by the LCS system immediately, immediately object UE is positioned, send positioning result to the request end at once then, be after the location information request of request end transmission is received by the LCS system, the current location information of object UE is provided to the request end immediately.
Fig. 2 initiates the flow chart of type location information request immediately for request end in the LCS standard of 3GPP, and as shown in Figure 2, the request end initiates immediately that the implementation procedure of type location information request may further comprise the steps:
Step 201～step 205: the request end sends LCS service request (LCS ServiceRequest) to R-GMLC, and request LCS system provides the positional information of object UE.After R-GMLC receives LCS ServiceRequest, send LCS routing iinformation request message (Send Routing Info forLCS) to HLR/HSS, request HLR/HSS provides the address of H-GMLC.After HLR/HSS receives Send RoutingInfo for LCS, send LCS routing iinformation response message (Send Routing Infofor LCS ACK), return the address information of H-GMLC to R-GMLC.After R-GMLC receives Send Routing Infofor LCS ACK, send LCS service request (LCS Service Request) to H-GMLC, request provides the positional information of object UE.After H-GMLC receives LCS Service Request, the LCS service request of R-GMLC and transmission thereof is carried out authentication, authentication success, execution in step 206; Otherwise H-GMLC sends error responses to R-GMLC.
Step 206～step 210:H-GMLC sends LCS routing iinformation request message (Send Routing Info for LCS) to HLR/HSS, and request HLR/HSS provides the address of V-GMLC and CN.After HLR/HSS receives Send Routing Info for LCS, send LCS routing iinformation response message (Send Routing Info for LCS ACK), return the address information of V-GMLC and CN to H-GMLC.After H-GMLC receives Send Routing Info for LCS ACK, send LCS service request (LCS Service Request) to V-GMLC, request provides the positional information of object UE.After V-GMLC receives LCS Service Request, send localizing objects UE request (ProvideSubscriber Location) to CN.After CN received Provide Subscriber Location, collaborative RAN positioned operation (Location Procedure) to object UE.
After step 211～step 213:CN finishes the object UE location,, return the positional information of object UE to the location response message (Provide Subscriber Location ACK) of V-GMLC transmission to object UE.After V-GMLC receives Provide Subscriber Location ACK, send LCS service response message (LCS Service Response), return the positional information that object UE is provided to H-GMLC.After H-GMLC received LCS Service Response, as required, H-GMLC carried out authentication to the positional information of the object UE that R-GMLC returns, authentication success, execution in step 214; Otherwise H-GMLC sends error responses to R-GMLC.
Step 214～step 215:H-GMLC sends LCS service response message (LCSService Response) to R-GMLC, returns the positional information of object UE.After R-GMLC receives LCS ServiceResponse, can carry out conversion process to the target UE locating result of returning as required, as latitude and longitude information being converted to local geography information; R-GMLC sends LCS service response message (LCS Service Response) to the request end, returns the positional information of conversion back final objective UE to the request end.
The delaying type position information request is meant that the request end requires the LCS system to provide the positional information of object UE to it when a time point or certain incident generation in the future, be after the location information request of request end to the object UE initiation received by the LCS system, need provide the current location information of object UE after the latency delays Event triggered again to the request end through delay after a while.
Fig. 3 is the flow chart that the delaying type position information request is initiated in the request end in the LCS standard of 3GPP, and as shown in Figure 3, the implementation procedure that the delaying type position information request is initiated in the request end may further comprise the steps:
Step 301～step 304: the request end is to R-GMLC transmission lag type LCS service request (LCSService Request), request LCS system provides the positional information of object UE, this LCS ServiceRequest contains the trigger event that object UE is positioned, for example, object UE is in case attached to just immediately it being positioned on the LCS network.R-GMLC transmits this LCS ServiceRequest to H-GMLC/V-GMLC after receiving the LCS Service Request that contains localizing objects UE trigger event; After H-GMLC/V-GMLC receives LCS Service Request, send localizing objects UE request (Provide Subscriber Location) to CN, contain the trigger event that object UE is positioned among this Provide Subscriber Location, request CN positions object UE when trigger event takes place.After CN receives the Provide SubscriberLocation that contains localizing objects UE trigger event, judge whether the trigger event condition satisfies, if satisfied directly initiation to the location of object UE, otherwise, the trigger event of CN store location object UE, send localizing objects UE response message (Provide Subscriber Location ACK) to H-GMLC/V-GMLC then, notice H-GMLC/V-GMLC, CN have accepted request and have held the delaying type position information request that object UE is initiated.After H-GMLC/V-GMLC receives Provide Subscriber Location ACK, send LCS service response message (LCS Service Response) to R-GMLC, notice R-GMLC, CN have accepted request and have held the delaying type position information request that object UE is initiated; After R-GMLC receives LCSService Response, transmit this LCS Service Response to the request end, notice request end CN has accepted its delaying type position information request that object UE is initiated.
Step 305～step 309: when trigger event takes place, CN judges the service request that object UE sends, as object UE request access network, satisfy the trigger event occurrence condition of storage, then CN thinks that the business request information that this object UE sends also is trigger event generation message (Requested Eventis Detected).After CN received Requested Event is Detected, collaborative RAN positioned operation (Location Procedure) to object UE.CN to the position message message (Subscriber LocationReport) that H-GMLC/V-GMLC sends object UE, returns target UE locating result after the object UE location is finished.After H-GMLC/V-GMLC receives SubscriberLocation Report,, notify the CN target UE locating result to receive to the position message response message (SubscriberLocation Report ACK) that CN sends object UE.Meanwhile, H-GMLC/V-GMLC sends LCS service response message (LCS ServiceResponse) to R-GMLC, comprise among this LCS Service Response that CN returns to target UE locating result; After R-GMLC receives LCS Service Response, can carry out conversion process to the target UE locating result of returning as required, as latitude and longitude information being converted to local geography information; R-GMLC sends LCS service response message (LCS Service Response) to the request end, returns the positional information of conversion back final objective UE to the request end.
In addition, 3GPP allows the request end to require the LCS system cycle to provide the positional information of object UE to it, be request end definition start time point and concluding time point and some cycles logic, require the LCS system to provide the positional information of object UE according to the periodicity logic to it in the period at this section.
In addition, periodic location information request and delaying type position information request can mutually combine, and promptly the request end can send cyclic delay type location information request to the LCS system.
Fig. 4 is the flow chart that cyclic delay type location information request is initiated in the request end in the LCS standard of 3GPP, and as shown in Figure 4, the implementation procedure that cyclic delay type location information request is initiated in the request end may further comprise the steps:
Step 401～step 402: the request end sends cyclic delay type LCS service request (LCS Service Request) to R-GMLC, request LCS system provides the positional information of object UE, contain the trigger event that object UE is positioned among this LCSService Request, for example, object UE is in case attached to just immediately it being positioned on the LCS network; And some cycles logic, i.e. cycle start time point, end cycle time point and time interval that object UE is positioned.R-GMLC at the cycle start time point according to periodicity logic start-up period timer.
After step 403～step 405:R-GMLC receives LCS Service Request, R-GMLC contains the trigger event that object UE is positioned to H-GMLC/V-GMLC transmission lag type LCS service request (LCS Service Request) among this LCS Service Request; After H-GMLC/V-GMLC receives LCS Service Request, send localizing objects UE request (ProvideSubscriber Location) to CN, contain the trigger event that object UE is positioned among this Provide Subscriber Location, request CN positions object UE when trigger event takes place.After CN receives the Provide Subscriber Location that contains localizing objects UE trigger event, judge whether the trigger event condition satisfies, if satisfied directly initiation to the location of object UE, otherwise, the trigger event of CN store location object UE, send localizing objects UE response message (Provide Subscriber Location ACK) to H-GMLC/V-GMLC then, notice H-GMLC/V-GMLC, CN have accepted request and have held the delaying type position information request that object UE is initiated.After H-GMLC/V-GMLC receives Provide Subscriber Location ACK, send LCS service response message (LCS Service Response) to R-GMLC, notice R-GMLC, CN have accepted request and have held the delaying type position information request that object UE is initiated; After R-GMLC receives LCS Service Response, transmit this LCS Service Response to the request end, notice request end CN has accepted its delaying type position information request that object UE is initiated.
After the cycle timer of R-GMLC was overtime, the state of R-GMLC has two kinds of situation: R-GMLC to be in wait restoring to normal position result phase and R-GMLC is not in wait restoring to normal position result phase.
It is as follows that R-GMLC is in the concrete steps of waiting for the restoring to normal position result phase:
The periodicity timer expiry of step 406a:R-GMLC, R-GMLC is in and waits for that CN returns the target UE locating result state, R-GMLC sends LCS service response message (LCS Service Response) to the request end, and the positional information of notice request end object UE temporarily can't provide.
Step 407a: after postponing a period of time, when trigger event takes place, CN judges the service request that object UE sends, as object UE request access network, satisfy the trigger event occurrence condition of storage, then CN thinks that the business request information that this object UE sends also is trigger event generation message (Requested Event is Detected).After CN received Requested Event is Detected, collaborative RAN positioned operation (Location Procedure) to object UE.
Step 408a～step 409a:CN to the position message message (Subscriber Location Report) that H-GMLC/V-GMLC sends object UE, returns target UE locating result after the object UE location is finished.After H-GMLC/V-GMLC receives Subscriber Location Report,, notify the CN target UE locating result to receive to the position message response message (Subscriber Location Report ACK) that CN sends object UE.Meanwhile, H-GMLC/V-GMLC sends LCS service response message (LCS Service Response) to R-GMLC, comprise among this LCS ServiceResponse that CN returns to target UE locating result; After R-GMLC receives LCSService Response, can carry out conversion process to the target UE locating result of returning as required, as latitude and longitude information being converted to local geography information; R-GMLC sends LCS service response message (LCS Service Response) to the request end, and the positional information of conversion back final objective UE is provided to the request end.
It is as follows that R-GMLC is not in the concrete steps of waiting for the restoring to normal position result phase:
The periodicity timer expiry of step 406b:R-GMLC, R-GMLC is not in and waits for that CN returns the target UE locating result state, R-GMLC to H-GMLC/V-GMLC transmission lag type LCS service request (LCS Service Request), contains the trigger event that object UE is positioned among this LCS Service Request once more.
Step 407b～step 409b and step 403～step 405 are basic identical.
Step 410b: trigger event takes place, CN judges the service request that object UE sends, as object UE request access network, satisfy the trigger event occurrence condition of storage, then CN thinks that the business request information that this object UE sends also is trigger event generation message (Requested Event is Detected).After CN received Requested Event is Detected, collaborative RAN positioned operation (Location Procedure) to object UE.
Step 411b～step 412b and step 408a～step 409a is basic identical.
Because positional information belongs to user's private information for object UE, its positional information should obtain strict protection.Request end for any request target UE positional information, the LCS system all needs it is carried out the legitimacy authentication, directly carry out authentication according to object UE setting in advance or request end information being sent to object UE in the LCS system by it, check whether object UE authorizes this its positional information of request end request by the LCS system.
Even the legitimacy authentication of LCS system has been passed through in certain request end, initiation is to the location information request of type immediately or the delaying type position information request of object UE, the LCS system also allows object UE to inquire about the current location information request that is in state of activation to its initiation at any time, and can cancel operation to these location information request.
In the LCS of 3GPP standard, propose to allow object UE to inquire about at any time or cancel the current active position information request that is in state of activation.The state of activation of location information request is meant that location information request is carved into the time period between the LCS system carries out positioning action to object UE the finish time, the residing state of location information request when sending to LCS system initial.Control logic for delaying type position information request localizing objects UE trigger event is stored in CN, the trigger event of CN store location object UE, and when trigger event takes place, object UE is positioned., by R-GMLC the periodic location information request is split as single location information request of type immediately or delaying type position information request, and sends in R-GMLC for the periodic Control logical storage of periodic location information request to CN.Therefore, for CN, and whether unclear received location information request belongs to the periodic location information request, be that activate or nonactivated also with regard to the state of not knowing the one-period location information request, and some other relevant informations of periodic location information request, the number of times that takes place as the zero-time in cycle, concluding time and periodic location information request etc.
When object UE when the LCS system initiates inquiry or canceling location information request, inquiry or cancellation operation sending to CN by RAN, CN can inquire about or cancels operation the current location information request that is in state of activation.But because CN can't know currently whether have the periodic location information request to be in state of activation, and other relevant informations of not knowing the periodic location information request, cause CN can't accurately intactly carry out inquiry or cancellation operation.
Summary of the invention
In view of this, the object of the present invention is to provide the information interacting method of periodic location information request in a kind of location service, position service system can accurately intactly be carried out the location information requested operation that target UE is initiated.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
When the periodic location information request is initiated in the request end, in article one LCS service period request (LCS ServiceRequest) that H-GMLC/V-GMLC sends, carry all cycle information parameters relevant at R-GMLC with the periodic location information request, time interval that positions as cycle start time point, end cycle time point and to object UE etc., in addition, carry a number simultaneously among this LCS Service Request by the R-GMLC Random assignment, as the ReferanceNumber number, be used to distinguish different periodic location information request.In the localizing objects UE request (Provide SubscriberLocation) that CN sends, also need the corresponding cycle information parameter relevant of carrying at H-GMLC/V-GMLC with the periodic location information request.After CN receives Provide Subscriber Location, know that according to the cycle information parameter among the Provide Subscriber Location this request is the periodic location information request, write down the ReferanceNumber number of this periodic location information request, the state of this periodic location information request is changed to activation.Meanwhile, other cycle information parameters among the CN storage Provide Subscriber Location, and can go out relevant information according to the cycle information parametric inference of period position information request, for example, can be according to the cycle start time point, end cycle time point and the cycle informations parameter such as the time interval that object UE is positioned, derive execution number of times by the end of this periodic location information request of a certain moment, apart from the periodic location information request remaining execution number of times finish time, a certain moment, whether this periodic location information request was in state of activation etc.No longer carry the cycle information parameter among the LCS ServiceRequest that sends in the R-GMLC subsequent process.
Existing sign realizes in the LCS Service Request message that ReferanceNumber also can send by R-GMLC.
The flow chart that Fig. 5 directly informs CN for R-GMLC of the present invention with periodic location information request relevant information, as shown in Figure 5, R-GMLC informs directly that with periodic location information request relevant information the implementation procedure of CN may further comprise the steps:
Step 501:R-GMLC carries all the associated period informations parameter with the periodic location information request in article one LCS service period request (LCS Service Request) that H-GMLC/V-GMLC sends, carry a number simultaneously by the R-GMLC Random assignment, as the ReferanceNumber number, be used for identifying each periodic location information request that this periodic location information request is initiated in the cycle.The ReferanceNumber of this moment represents which periodic location information request this request belongs to.
After step 502:H-GMLC/V-GMLC receives article one LCS Service Request, send article one localizing objects UE periodic request (Provide Subscriber Location) to CN, carry all the associated period informations parameter with the periodic location information request among this Provide Subscriber Location equally, and ReferanceNumber.After CN receives article one Provide SubscriberLocation, know that according to the cycle information parameter this request is first periodic location information request in the periodic location information request, write down corresponding ReferanceNumber, and the state of this periodic location information request is changed to activation, carry out subsequent treatment then.
Step 503:R-GMLC sends second LCS service period request (LCS Service Request) to H-GMLC/V-GMLC, can only carry a ReferanceNumber among this LCS Service Request, represent which periodic location information request this request belongs to.The content that R-GMLC carries in the LCS of the follow-up transmission of H-GMLC/V-GMLC service period request (LCS ServiceRequest) is consistent with foregoing.
After step 504:H-GMLC/V-GMLC receives second LCS Service Request, send second localizing objects UE periodic request (Provide Subscriber Location) to CN, can only carry a ReferanceNumber equally among this Provide Subscriber Location.CN carries out subsequent treatment after receiving second Provide Subscriber Location.
The implementation procedure that cyclic delay type location information request is initiated in subsequent treatment and foregoing request end is similar, does not repeat them here.
In the LCS of mobile communications network, can make CN obtain the relevant information of periodic location information request by the present invention.When object UE was initiated the location information requested operation, to the location information request that object UE is initiated, CN can accurately intactly carry out operational processes at all.R-GMLC directly sends the relevant information of periodic location information request to CN, CN can go out other relevant informations according to the information inference that obtains.When object UE was initiated the operations such as inquiry, cancellation of location information request, CN can guarantee accurately intactly execution to the operation of periodic location information request by enough information.
When R-GMLC need initiate the one-period location information request, in article one LCS service period request (LCS ServiceRequest) that H-GMLC/V-GMLC sends, carry a distinctive mark at R-GMLC, as the PeriodicStartFlag sign, show that this request is first request in the periodic location information request; Also will carry a ReferanceNumber number by the R-GMLC Random assignment simultaneously, as 12345, this number is used for discerning the LCS service period request of same periodic location information request.In article one localizing objects UE periodic request (Provide Subscriber Location) that CN sends, correspondingly carry PeriodicStartFlag sign and ReferanceNumber number subsequently at H-GMLC/V-GMLC, the PeriodicStartFlag sign is used for notifying CN to trigger the periodic location information request, and the ReferanceNumber number is used for allowing the follow-up LCS service period request (LCS Service Request) of CN identification whether belong to this periodic location information request.CN finds the PeriodicStartFlag sign in the Provide Subscriber Location that receives, know that then this location information request is the periodic location information request, and this moment, this periodic location information request was in state of activation, promptly stored the ReferanceNumber number among the Provide SubscriberLocation.
When R-GMLC needs the end period location information request, in the last item LCS service period request (LCS Service Request) that sends to H-GMLC/V-GMLC, need carry a distinctive mark equally, indicate as PeriodicEndFlag, show this request be in the periodic location information request last the request, and need carry with article one LCS Service Request in identical random number.In the localizing objects UE periodic request (Provide Subscriber Location) that CN sends, also need carry PeriodicEndFlag sign and ReferanceNumber number subsequently at H-GMLC/V-GMLC, PeriodicEndFlag sign is used for notifying this periodic location information request of CN to finish, and which periodic location information request what the ReferanceNumber number was used for allowing the CN end of identification is.
Therefore, CN just can derive some periodic location information request compactly and whether be in state of activation by the analysis to PeriodicStartFlag sign, PeriodicEndFlag sign and ReferanceNumber number.
When object UE when CN initiates the inquiry of the current location information request that is in state of activation or cancellation operation, CN can handle the periodic location information request that is in state of activation.When CN discovery self can not be when object UE provides the relevant information of more relevant periodic location information request, for example, object UE need start time point, the concluding time point of polling cycle property location information request and number of times that periodic request takes place, apart from the remaining number of times of periodic location information request request dot cycle concluding time.CN can send information inquiring request by H-GMLC/V-GMLC to R-GMLC further, and request R-GMLC returns the relevant information of corresponding periodic location information request to it.
In addition, at R-GMLC identical random number ReferanceNumber number among portability and article one LCS Service Request in all LCS service period requests of centre (LCS Service Request) that H-GMLC/V-GMLC sends, H-GMLC/V-GMLC carries corresponding ReferanceNumber number equally in all localizing objects UE periodic request of centre (Provide Subseriber Location) that CN sends, carry out the statistics of some simple periodic information with auxiliary CN, as draw the number of times that the periodic location information request takes place.
In actual applications, PeriodicStartFlag sign, PeriodicEndFlag sign and ReferanceNumber number can be represented by the mode that sets in advance by a field in the message, in F123450, the F of beginning represents the PeriodicStartFlag sign effectively, 12345 is the ReferanceNumber number that generates at random, and 0 of end represents the PeriodicEndFlag sign invalid; And for example among the 012345F, 0 of beginning represents the PeriodicStartFlag sign invalid, and 12345 is the ReferanceNumber number that generates at random, and the F at end represents the PeriodicEndFlag sign effectively.
Fig. 6 increases the flow chart that flag bit is informed CN periodic location information request relevant information for R-GMLC of the present invention in request, as shown in Figure 6, R-GMLC increases flag bit and informs that the implementation procedure of CN periodic location information request relevant information may further comprise the steps in request:
Step 601～step 602: carry in article one LCS service period request (LCS Service Request) that H-GMLC/V-GMLC sends at R-GMLC and to show that this request is the PeriodicStartFlag sign of first request in the one-period location information request, carry a ReferanceNumber number simultaneously, in order to discern all requests in the same periodic location information request by the R-GMLC Random assignment.After H-GMLC/V-GMLC receives article one LCS Service Request, send article one localizing objects UE periodic request (Provide Subscriber Location) to CN, correspondingly carry PeriodicStartFlag sign and ReferanceNumber number among this Provide Subscriber Location.After CN receives this Provide Subscriber Location, know that according to its PeriodicStartFlag that carries sign this request is first request in the periodic location information request, record ReferanceNumber number, the state of this periodic location information request is changed to activation, carries out subsequent treatment.
If initiate N second periodicity location information request altogether in the cycle, then step 603～step 604 is for initiating the information interactive process of the second time to N-1 second periodicity location information request, and this information interactive process and step 503～step 504 are basic identical.
Step 605～step 606: carry in the last item LCS service period request (LCS Service Request) that H-GMLC/V-GMLC sends at R-GMLC and to show that this request is the PeriodicEndFlag sign of last periodic request in the one-period location information request, carries identical ReferanceNumber number simultaneously.The PeriodicEndFlag sign shows that this request is last request in the periodic location information request, and the ReferanceNumber number shows that this request belongs to some periodic location information request.After H-GMLC/V-GMLC receives the last item LCS ServiceRequest, send the last item localizing objects UE periodic request (Provide SubscriberLocation) to CN, correspondingly carry PeriodicEndFlag sign and ReferanceNumber number among this Provide Subscriber Location.After CN receives this Provide Subscriber Location, know that according to its PeriodicEndFlag that carries sign this request is last request in the periodic location information request, and go out corresponding periodic location information request according to the ReferanceNumber number searching, write down this periodic location information request and be about to enter done state, carry out subsequent treatment then.CN is changed to done state with the state of this periodic location information request after last periodic location information request is finished localization process.
Because it is a non-recurrent action that object UE is initiated CN location information requested operation, the present invention is by increasing the state information that sign is notified the CN periodic request in periodic request, the information CN more detailed for the periodic location information request can provide periodic location information request relevant information flow process to obtain by initiate request to R-GMLC, saves a large amount of signaling loads.
Fig. 7 provides the flow chart of periodic location information request relevant information for CN of the present invention asks R-GMLC, and as shown in Figure 7, CN request R-GMLC provides the implementation procedure of periodic location information request relevant information to comprise following steps:
Step 701～step 702: when CN needs R-GMLC that periodic location information request relevant information is provided, CN sends to H-GMLC/V-GMLC periodic location information request request-related information message (Provide Periodic LCS Request Info) is provided, and carries the address of R-GMLC and the ReferanceNumber number of corresponding periodic location information request among this Provide Periodic LCSRequest Info; Can further carry the periodic location information request relevant information sign that request R-GMLC provides among this Provide Periodic LCS Request Info.H-GMLC/V-GMLC is forwarded to R-GMLC by the R-GMLC address of carrying among the Provide Periodic LCS Request Info with this Provide Periodic LCS Request Info.
After step 703～step 704:R-GMLC receives Provide Periodic LCS Request Info, search corresponding periodic location information request according to the ReferanceNumber number that carries among this Provide Periodic LCS Request Info, send the response message (Provide Periodic LCS Request Info ACK) that periodic location information request relevant information is provided to H-GMLC/V-GMLC, return the relevant information of this periodic location information request.After H-GMLC/V-GMLC receives this ProvidePeriodic LCS Request Info ACK, transmit Provide Periodic LCS RequestInfo ACK to CN, CN obtains the relevant information of this periodic location information request.
In addition, when CN can arrive R-GMLC according to the address information pathfinding of R-GMLC, CN can directly send to R-GMLC provide periodic location information request request-related information message (Provide Periodic LCS Request Info); When R-GMLC can arrive CN according to the address information pathfinding of CN, R-GMLC can directly send the response message (Provide Periodic LCS Request Info ACK) that periodic location information request relevant information is provided to CN, returns the relevant information of this periodic location information request.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
