Description
Technical field
The present invention relates to network equipment location technology, be meant a kind of processing method of subscriber equipment initiation location information request 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 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 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, only at the GMLC of object UE ownership, be after H-GMLC obtains the process information of service request, could carry out correct wholesale price to business when pre-treatment, and generate corresponding ticket writing, thereby realize charging to object UE, because there is very big uncertainty in the GMLC that relates in the MO-LR request processing procedure, both can set arbitrarily by object UE, therefore also can specify arbitrarily, exist the possibility that correctly to charge to the MO-LR request that object UE is initiated largely by CN.
In addition, object UE is to the positional information of the network requests that comprises the LCS system self, and do not require when the network that comprises the LCS system offers the external request end with the object UE positional information, because CN passes through RAN directly to object UE restoring to normal position result, H-GMLC does not get access to current MO-LR processing of request information equally, therefore, also can't correctly charge to the MO-LR request that object UE is initiated.
Comprehensive above the description according to the MO-LR request processing flow of existing 3GPP normalized definition, can't correctly be chargeed to the MO-LR request that object UE is initiated at all.

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.
Among the present invention, object UE is to the positional information of the network requests that comprises the LCS system self, CN get access to RAN to target UE locating result after, at first provide target UE locating result to H-GMLC, after H-GMLC handles Location Request, and then provide positioning result to object UE via CN, owing to obtained MO-LR processing of request information among the H-GMLC, therefore can correctly charge to the MO-LR request that object UE is initiated.
Fig. 3 is MO-LR processing of request flow chart among the present invention, and as shown in Figure 3, MO-LR processing of request process may further comprise the steps:
Step 301: 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 302 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 302~step 304: object UE sends location service MO-LR request via RAN to CN, and request CN positions object UE.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, CN sends localizing objects UE request to RAN.RAN positions object UE after receiving localizing objects UE request.
Behind the step 305~location of step 306: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 RAN does not successfully position object UE, then carry the error cause value in this object UE position message.After CN receives the object UE position message, send the MO-LR location request to H-GMLC, notice H-GMLC object UE has been initiated the MO-LR request.
For H-GMLC can accurately be chargeed according to MO-LR processing of request situation, after CN receives the object UE position message, can be according to the content of carrying in the object UE position message, send the MO-LR location request that carries corresponding contents to H-GMLC, the MO-LR processing of request situation that notice H-GMLC object UE is initiated, if promptly CN receives the object UE position message that carries the object UE positional information, then send the MO-LR location request carry successful sign or object UE positional information to H-GMLC; If CN receives the object UE position message that carries the error cause value, then send the MO-LR location request that carries the failure sign to H-GMLC, further, CN goes back portability in the MO-LR location request that H-GMLC sends has object UE to initiate the type of MO-LR request.In addition, when CN received the object UE position message that carries the error cause value, also direct execution in step 308 was returned the location service MO-LR response that carries the error cause value via RAN to object UE, finishes current MO-LR processing of request flow process.
CN obtains the H-GMLC address information of object UE by following dual mode: owing to store the H-GMLC address information of object UE among the HLR/HSS, therefore can be when the current place CN of object UE downloads the relevant user data of object UE at HLR/HSS, the H-GMLC address information is downloaded among the CN in the lump, and the CN storage comprises the user data of H-GMLC address information.In addition, also can carry the H-GMLC address information in this location service MO-LR request in object UE when CN sends location service MO-LR request, CN stores this H-GMLC address information after receiving the location service MO-LR request that carries the H-GMLC address information.
Therefore, above CN sends in the process of MO-LR location request to H-GMLC, stores the address information of H-GMLC among the CN, and according to the H-GMLC address information of self storing, judge whether directly to insert H-GMLC, if then directly send the MO-LR location request to H-GMLC; Otherwise, CN 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 MO-LR location request that carries the H-GMLC address information to V-GMLC, send the MO-LR location request to H-GMLC by V-GMLC.
After step 307~step 308:H-GMLC receives the MO-LR location request, can carry out the legitimacy authentication to object UE earlier, as verify whether the contracted MO-LR business of its initiation of object UE, whether the account balance of object UE is sufficient or the like, after object UE has been passed through the legitimacy authentication, the relevant information of the MO-LR request that H-GMLC storage object UE is initiated, and generate corresponding ticket writing, return the response of MO-LR location request to CN then.After this moment, CN received the response of MO-LR location request, the content of carrying in the object UE position message that returns according to RAN, return the location service MO-LR response that carries corresponding contents to object UE via RAN, if promptly CN receives the object UE position message that carries the object UE positional information, then return the location service MO-LR response that carries the object UE positional information to object UE; If CN receives the object UE position message that carries the error cause value, then return the location service MO-LR response that carries the error cause value to object UE.In addition, at H-GMLC in the response of MO-LR location request that CN returns, can further carry the MO-LR processing of request situation that UE initiates, the corresponding contents that carries in the location request response message that this moment, CN also can return according to H-GMLC is to the professional MO-LR response of object UE home position.If object UE is failed by the legitimacy authentication, then H-GMLC returns the MO-LR location request response that carries the error cause value to CN, CN returns the location service MO-LR response that carries the error cause value via RAN to object UE, finishes current MO-LR processing of request flow process.
Can further carry external request end (LCS Client) sign in the location service MO-LR request that object UE is initiated, and by the GMLC address of object UE appointment, require the LCS system that the object UE positional information the obtained GMLC by appointment is offered the external request end, when then RAN successfully positions object UE, when H-GMLC has obtained the positional information of object UE and has judged object UE to belong to validated user, subsequent process is: when object UE has been specified the GMLC address, H-GMLC directly provides the positional information of object UE to this GMLC, GMLC transmits the positional information of object UE again to the request end; Otherwise H-GMLC obtains the request end address information according to the request end sign that CN provides, and judging whether directly to provide the object UE positional information to the request end, if then directly provide the object UE positional information to the request end; Otherwise, according to the request end address information, search the GMLC that can directly insert the request end, send the object UE positional information by this GMLC to the request end then.
Above-mentioned processing mode is to send the MO-LR location request by the positional information of CN controlled target UE to H-GMLC, and another kind of processing mode is that the positional information by V-GMLC controlled target UE sends to H-GMLC.After obtaining the positional information of object UE at CN, CN distributes the V-GMLC that self can insert, send the MO-LR location request to V-GMLC, the information of the object UE of carrying in location service MO-LR request is arranged in this MO-LR location request, V-GMLC judges whether object UE requires the positional information of himself is offered the request end, if then V-GMLC obtains the address information of H-GMLC according to the GMLC address information of self storing; Or mutual by with HLR/HSS, obtain the address information of H-GMLC, send the MO-LR location request to H-GMLC then, H-GMLC can be that object UE is distributed corresponding pseudo-code according to the object UE real mark in the MO-LR location request, or request distributes the pseudo-code management entity (PMD of pseudo-code, Pseudonym Management Device) distributes corresponding pseudo-code for object UE, substitute the real mark of object UE, real mark to request end vanishing target UE, then, H-GMLC judges the GMLC address information of whether having carried the object UE appointment in the MO-LR location request, if, then H-GMLC directly provides the positional information of object UE to this GMLC, and GMLC transmits the positional information of object UE again to the request end; Otherwise, H-GMLC identifies according to the request end in the MO-LR location request message, judge whether directly to insert this request end, if, then directly provide the positional information of object UE, otherwise H-GMLC is according to the request end address information to this request end, search the GMLC that can directly insert the request end, send the object UE positional information by this GMLC to the request end then.If object UE does not require the positional information with self and offers the request end, then V-GMLC handles the positional information of object UE, as generate corresponding charge information, return the response of MO-LR location request to CN then, CN is to the professional MO-LR request of object UE home position response, and the MO-LR that target end UE initiates asks flow processing.
CN get access to RAN to target UE locating result after, distribute the V-GMLC that self can insert, provide target UE locating result to V-GMLC then, write down corresponding charge information by V-GMLC.V-GMLC is by certain operation means, as adopting the mode of inter-network settlement, this charge information passed to the home network operator of object UE, carries out correct charging by the home network operator of object UE.
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 does not carry external request end sign 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, and 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.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 (LCSCS_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/MSCServer sends localizing objects UE request (Location Request) to RAN; After RAN receives LocationRequest, object UE is positioned.
Behind the location of step 407:RAN end to object UE, return the object UE position message message (Location Report) that carries the object UE positioning result to MSC/MSC Server.After MSC/MSCServer receives Location Report, according to the H-GMLC address information of self storing, judge whether directly to insert H-GMLC, if, then directly send the object UE position message (MAP Subscriber Location Report) that carries the object UE positioning result to H-GMLC, otherwise, MSC/MSC Server is according to the stored information of self, or by with network in the mutual acquisition self of other entities V-GMLC address information that can directly insert, execution in step 408 then.
If in the LCS CS_MO_LR Invoke that MSC/MSC Server sends, carry the H-GMLC address information in object UE, or the user data that HLR/HSS will comprise the H-GMLC address information is downloaded among the MSC/MSC Server at the current place of object UE, then stores the H-GMLC address information among the MSC/MSC Server.
