Description

A kind of processing method that position information of user equipment is provided to the request end
Technical field
The present invention relates to network equipment location technology, be meant especially when a kind of subscriber equipment is initiated location information request, the processing method of position information of user equipment is provided to the request end.
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 is meant the device end that is positioned in the mobile communications network, and positional information can be the latitude and longitude information of geography or the positional information in local street.The positional information that mobile communications network obtains can offer object UE, is used for the self poisoning of object UE; Also can offer communication network itself, be used for the subregion and charge or Operation and Maintenance; 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 LCS standard and whole realization location service in third generation partner program (3GPP) all are described.
Fig. 1 is for realizing the logical construction schematic diagram of location service, as shown in Figure 1, the positional information of the network 102 request target UEs 103 of request end 101 by comprising the LCS system, the legitimacy authentication is carried out in the 102 pairs of request ends of network 101 that comprise the LCS system, whether checking object UE 103 allows to this request end 101 its positional informations, if the legitimacy authentication of the network 102 of request end 101 by comprising the LCS system, the location information request that the network 102 that then comprises the LCS system accepts request and holds 101 pairs of object UE 103 to initiate, object UE 103 is positioned, and provide positioning result object UE 103 to this request end 101; Otherwise the network 102 that comprises the LCS system is refused the location information request that 101 pairs of object UE in request ends 103 are initiated.
The function logic entity that can realize location service in the LCS system comprises Gateway Mobile Location Center (GMLC), storage of subscriber data server (HLR/HSS), core network (CN) and Radio Access Network (RAN).GMLC can further comprise request Gateway Mobile Location Center (R-GMLC, Requesting GMLC), home gateway mobile positioning center (H-GMLC, Home GMLC) and visit Gateway Mobile Location Center (V-GMLC, Visited GMLC).R-GMLC is meant the GMLC of reception request end to the location information request of object UE initiation, and H-GMLC is meant the GMLC that object UE belongs to, and V-GMLC is meant current GMLC for the object UE service, the i.e. GMLC at the current place of object UE.R-GMLC, H-GMLC and V-GMLC can be same physical entity, also can be different physical entities.
At present, defined mobile originating location information request (MO-LR in the 3GPP standard, MobileOriginal Location Request) handling process, the MO-LR request is meant the positional information of object UE to LCS system request self, the LCS system returns to object UE with positioning result after object UE is positioned; Further, the LCS system can offer certain outside request end with target UE locating result according to the requirement of object UE.Request end herein is meant the client that LCS client, applications client etc. can be handled the object UE positional information, is not the request end of the request target UE positional information on the ordinary meaning.
Fig. 2 is a MO-LR processing of request flow chart in the prior art, and as shown in Figure 2, MO-LR processing of request process may further comprise the steps:
Step 201: object UE sends service request via RAN to CN, request is set up wireless signaling with the network that comprises the LCS system and is connected, the network that comprise the LCS system this moment may be initiated authentication and the encryption flow to object UE, if object UE then continues execution in step 202 by comprising the authentication of LCS grid; Otherwise the service request that is used for the wireless signaling connection that the refusal object UE is initiated finishes the current handling process that MO-LR asks.
Step 202~step 204: object UE sends location service MO-LR request via RAN to CN, request CN positions object UE, can further carry the information of external request end in this location service MO-LR request, require the LCS system that the object UE positional information of obtaining is offered the respective request end.After CN receives location service MO-LR request, can judge whether the contracted MO-LR business of its initiation of object UE according to canned data, if the not signatory MO-LR business of object UE, then CN returns the location service MO-LR request response that carries the error cause value, the MO-LR request that the refusal object UE is initiated to object UE.The MO-LR business if object UE has been contracted, then CN sends the localizing objects UE request that carries the object UE sign to RAN; Also can further carry the GMLC address that can be linked into the request end of object UE appointment in this location service MO-LR request, require CN to provide target UE locating result to the request end by specifying GMLC.If object UE is not specified GMLC, then CN can for current MO-LR request distributes a GMLC, provide target UE locating result by this GMLC to the request end according to the GMLC address information of self storing.RAN positions object UE after receiving localizing objects UE request.
Behind the location of step 205:RAN end to object UE, return the object UE position message to CN, if RAN successfully positions object UE, promptly can obtain the positional information of object UE, then carry the positional information of object UE in this object UE position message, if object UE requires the LCS system that the object UE positional information of obtaining is offered the respective request end, after then CN receives the object UE position message, continue execution in step 206~step 210; Otherwise CN directly returns the location service MO-LR response that carries positional information to object UE by RAN.If RAN does not successfully position object UE, then carry the error cause value in this object UE position message, CN returns the location service MO-LR response that carries the error cause value by RAN to object UE.
Step 206~step 207:CN sends the object UE position message to the GMLC of appointment, carries request end sign and object UE positional information in this object UE position message.After GMLC receives the object UE position message, send the object UE positional information to the respective request end according to the request end sign.
Step 208~step 209: after the positional information of object UE is received in the request end, judge whether and to handle the positional information of object UE, if then return and carry the successfully object UE location information response of sign to GMLC; Otherwise, return the object UE location information response that carries the error cause value to GMLC.After GMLC receives the object UE location information response, according to the content of carrying in the object UE location information response, return the object UE position message response that carries corresponding contents to CN, if promptly GMLC receives and carries the successfully object UE location information response of sign, then return and carry the successfully object UE position message response of sign to CN; If GMLC receives the object UE location information response that carries the error cause value, then return the object UE position message response that carries the error cause value to CN.
After step 210:CN receives the response of object UE position message, according to the content of carrying in the response of object UE position message, return the location service MO-LR response that carries corresponding contents to object UE, if promptly CN receives and carries the successfully object UE position message response of sign, then return the location service MO-LR response that carries positional information, and notification target UE provides positional information to the respective request end to object UE; If CN receives the object UE position message response that carries the error cause value, then return the location service MO-LR response that carries positional information to object UE, and to object UE return error cause value, notification target UE provides positional information to the respective request end, but the respective request end can't correctly be handled its positional information.
As seen MO-LR by above-mentioned 3GPP normalized definition asks processing procedure, when the positional information of object UE to the network requests that comprises the LCS system self, and the network that requires to comprise the LCS system is when offering the external request end with the object UE positional information, after CN obtains the positional information of object UE, provide the positional information of object UE to outside request end by GMLC.Above-mentioned GMLC can be specified in location service MO-LR request by object UE, also can be specified arbitrarily according to the GMLC address information of self storing by CN.
In the network operation of reality, when the address information of GMLC was specified by object UE, the CN at the current place of object UE possibly can't be linked among this GMLC, did not belong to same network as the GMLC of current place CN of object UE and object UE appointment; When the address information of GMLC is divided timing by CN, this moment, CN can distribute the GMLC that self can directly insert according to the GMLC address information of storage, but this GMLC possibly can't be linked in the request end of appointment, promptly can directly insert the GMLC of request end, different with the GMLC of CN appointment.For this situation, utilize existing MO-LR handling process, the positional information of object UE can't be offered the request end of object UE appointment, make carrying out of MO-LR business have significant limitation.
Summary of the invention

After step 307:V-GMLC receives the object UE position message, if carry the GMLC address information in the object UE position message, then send the MO-LR locating information notice that carries object UE positional information, request end sign and object UE sign to corresponding GMLC.When not carrying the GMLC address information in the object UE position message, then V-GMLC is according to the request end sign of carrying in the object UE position message, obtain the address information of request end, judge whether directly to insert this request end, if, then V-GMLC directly sends object UE positional information, corresponding omission step 307 and 310 to the request end; Otherwise, V-GMLC is according to the address information of request end, search the GMLC address information that can directly insert the request end, send the MO-LR locating information notice that carries object UE positional information, request end sign and object UE sign to this GMLC, notice GMLC object UE requires its positional information is offered the request end of appointment.
After step 308:GMLC receives MO-LR locating information notice, according to the request end sign of carrying in the MO-LR locating information notice, judge whether directly to insert this request end, if then send the object UE location information message that carries the object UE positional information to the request end; Otherwise GMLC directly returns the MO-LR locating information push-notification-answer that carries failure reason value to V-GMLC.
GMLC is judging can not directly insert the specified request end time, also can be according to the address information of request end, search another GMLC that can directly insert this request end, send the object UE location information message by this another GMLC that searches to the request end then, continue execution in step 309 then.
Step 309~step 311: after the positional information of object UE is received in the request end, judge whether and to handle the positional information of object UE, if then return and carry the successfully object UE location information response of sign to GMLC; Otherwise, return the object UE location information response that carries the error cause value to GMLC.After GMLC receives the object UE location information response, according to the content of carrying in the object UE location information response, return the object UE position message response that carries corresponding contents to CN, if promptly GMLC receives and carries the successfully object UE location information response of sign, then return and carry the successfully object UE position message response of sign to CN; If GMLC receives the object UE location information response that carries the error cause value, then return the object UE position message response that carries the error cause value to CN.
If CN provides the object UE positional information by V-GMLC to GMLC, then GMLC returns the MO-LR locating information push-notification-answer that carries corresponding contents to V-GMLC earlier, if promptly GMLC receives and carries the successfully object UE location information response of sign, then return and carry the successfully MO-LR locating information push-notification-answer of sign to V-GMLC; If GMLC receives the object UE location information response that carries the error cause value, then return the MO-LR locating information push-notification-answer that carries the error cause value to V-GMLC.V-GMLC returns the object UE position message response of carrying corresponding contents to CN.
After step 312:CN receives the response of object UE position message, according to the content of carrying in the response of object UE position message, return the location service MO-LR response that carries corresponding contents to object UE, if promptly CN receives and carries the successfully object UE position message response of sign, then return the location service MO-LR response that carries positional information, and notification target UE provides positional information to the respective request end to object UE; If CN receives the object UE position message response that carries the error cause value, then return the location service MO-LR response that carries positional information to object UE, and to object UE return error cause value, notification target UE provides positional information to the respective request end, but the respective request end can't correctly be handled its positional information.
Fig. 4 is an embodiment schematic diagram among the present invention, and as shown in Figure 4, in the present embodiment, the circuit domain MO-LR processing of request process that carries external request end sign and can directly insert the GMLC address information of request end may further comprise the steps:
Step 401~step 403: object UE sends call management service request (CM ServiceRequest) to RAN, and request is connected with network road construction wireless signaling.After RAN receives CM Service Request, transmit this CM Service Request to mobile switching centre (MSC)/Mobile Switching Center Server (MSC Server).After MSC/MSC Server receives CM Service Request, carry out finishing authentication ciphering, if object UE is passed through authentication alternately with object UE to object UE, MSC/MSC Server notification target UE has accepted the call management service request of its initiation, continues execution in step 404; Otherwise MSC/MSC Server notification target UE refuses the call management service request of its initiation.
Step 404~step 406: object UE is by after the authentication of MSC/MSC Server, to MSC/MSC Server transtation mission circuit territory location service MO-LR request (LCS CS_MO_LRInvoke), the network that request comprises the LCS system positions it, and carry the GMLC address information that the external request end identified and can directly insert the request end among the LCS CS_MO_LRInvoke, require MSC/MSC Server that the positional information of object UE is offered the respective external request end.After MSC/MSC Server receives LCS CS_MO_LR Invoke, can judge whether the contracted MO-LR business of its initiation of object UE according to canned data, if the not signatory MO-LR business of object UE, then MSC/MSC Server returns the circuit domain location service MO-LR response (LCS CS_MO_LR Result) that carries the error cause value to object UE, the MO-LR request that the refusal object UE is initiated.Otherwise MSC/MSC Server sends localizing objects UE request (LocationRequest) to RAN; RAN positions object UE after receiving Location Request.
After step 407:RAN finishes location to object UE, successfully obtain the positional information of object UE after, return the object UE position message message (Location Report) that carries the object UE positioning result to MSC/MSC Server.
After step 408:MSC/MSC Server receives Location Report, according to the GMLC address information of carrying among the LCSCS_MO_LR Invoke, judge whether directly to insert this GMLC, if can, then MSC/MSC Server directly sends the MAP Subscriber LocationReport that carries object UE positional information, request end sign and object UE sign to this GMLC, execution in step 410 then, corresponding omission step 409 and step 412.If MSC/MSCServer can not directly be linked into this GMLC, then MSC/MSC Server can be according to self canned data, or by with network in other entities mutual, obtain the V-GMLC address information that self can directly insert, transmit the MAP Subscriber Location Report that carries object UE positional information, request end sign, object UE sign and GMLC address information to V-GMLC, execution in step 409 then.
After step 409:V-GMLC receives MAP Subscriber Location Report, according to the GMLC address information of carrying among the MAPSubscriber Location Report, carry object UE positional information, request end sign and object UE sign MO-LR Location Inform to the GMLC transmission, notice GMLC object UE has been initiated the MO-LR request.
After step 410~step 412:GMLC receives MO-LR Location Inform,, send the Location Information that carries the object UE positional information to the request end according to the request end sign.After Location Information is received in the request end, judge whether and to handle the positional information of this object UE, if can, then return and carry the successfully Location InformationAck of sign to GMLC, otherwise, return the Location Information Ack that failure identifies to GMLC, can further carry corresponding error cause value.After GMLC receives Location Information Ack, return MO-LR Location Inform Ack to V-GMLC.
After step 413~step 414:V-GMLC receives MO-LR Location Inform Ack, the content of carrying according to MO-LR Location Inform Ack, be the positional information that whether request end can successful processing target UE and the positional information of object UE, generate corresponding ticket writing, return corresponding object UE position message response (Subscriber LocationReport Ack) to MSC/MSC server then.After MSC/MSC server receives Subscriber Location Report Ack, carry the circuit domain location service MO-LR response (LCS CS_MO_LR Result) of request end to the position information process result of object UE to the object UE transmission.
Step 415: the LCS system resource of release busy, finish current circuit domain MO-LR request processing flow.
Fig. 5 is another embodiment schematic diagram among the present invention, as shown in Figure 5, in the present embodiment, carries external request end sign, but the packet domain MO-LR processing of request process that does not carry the GMLC address information that can be linked into the request end may further comprise the steps:
Step 501~step 502: object UE sends business request information (CM Service Request) to service universal grouping wireless business supporting node (SGSN), and request is connected with network road construction wireless signaling.After SGSN received CM Service Request, the signaling of setting up packet domain with object UE was connected.
