Description
Technical field
The present invention relates to the location technology of the network equipment, be meant the method for restriction site information request in region 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 the GMLC in the object UE 107 ownership LCS networks, 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.
Fig. 2 is that flow chart to the object UE location information request is initiated in the request end in the LCS standard of 3GPP, and as shown in Figure 2, the request end initiates the implementation procedure of object UE location information request be may further comprise the steps:
Step 201～step 202: the request end sends LCS service request (LCS ServiceRequest) to R-GMLC, request LCS system provides the positional information of object UE, the authentication information of the request target UE positional information that the portability request end provides among this LCS Service Request, for example Codeword.After R-GMLC receives LCS Service Request, send LCS routing iinformation request message (Send Routing Info for LCS) to HLR/HSS, request HLR/HSS provides the address of H-GMLC.
After step 203: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 H-GMLC to R-GMLC; In addition, HLR/HSS can return the address information of V-GMLC and the current place CN of object UE simultaneously in this Send Routing Info for LCS ACK.
After step 204:R-GMLC receives Send Routing Info for LCS ACK, send LCS service request (LCS Service Request) to H-GMLC, request provides the positional information of object UE.If HLR/HSS has returned the address information of V-GMLC and the current place CN of object UE simultaneously in step 203, then R-GMLC is transmitted to H-GMLC with the address information of V-GMLC and the current place CN of object UE.
After step 205:H-GMLC receives LCS Service Request, LCS service request to R-GMLC and transmission thereof is carried out authentication, judge whether present networks accepts the location information request of R-GMLC, H-GMLC judges that according to the object UE CAMEL-Subscription-Information of storage whether the request end is by the object UE mandate simultaneously, for example the authentication information Codeword that the request end provides in object UE CAMEL-Subscription-Information and the LCS service request is consistent, show that then the request end is by the object UE mandate, more than two conditions all satisfy, then authentication success, execution in step 206; Otherwise H-GMLC sends error responses to R-GMLC, and R-GMLC carries the error cause value to this request end restoring to normal position failed message in this location failed message.
Step 206～step 207: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.If R-GMLC is transmitted to H-GMLC with the address information of V-GMLC and CN in the step 204, then above step can be omitted.
Step 208～step 210:H-GMLC sends LCS service request (LCSService Request) to V-GMLC, and request provides the positional information of object UE, the address information of carrying the current place CN of object UE among this LCS Service Request.After V-GMLC receives LCS Service Request, send localizing objects UE request (Provide Subscriber Location) to CN.After CN received Provide Subscriber Location, collaborative RAN positioned operation (LocationProcedure) to object UE.
Step 211～step 212:CN to the location response message (Provide Subscriber Location ACK) of V-GMLC transmission to object UE, returns target UE locating result information after the object UE location is finished.After V-GMLC receives Provide Subscriber Location ACK, send LCS service response message (LCS Service Response), return the object UE locating result information that CN provides to H-GMLC.
After step 213:H-GMLC receives LCS Service Response, whether determine needs authentication once more according to the CAMEL-Subscription-Information of object UE, authentication if desired, can to providing the object UE locating result information of returning to carry out authentication to the request end, authentication be successful, execution in step 214, failed authentication, H-GMLC sends error responses to R-GMLC, and R-GMLC carries the error cause value to this request end restoring to normal position failed message in this location failed message; If do not need authentication, direct execution in step 214.
Step 214～step 215:H-GMLC sends LCS service response message (LCSService Response) to R-GMLC, returns target UE locating result information.After R-GMLC receives LCSService Response, can carry out conversion process to the object UE locating result information 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), the object UE positional information after conversion is returned in the request end to the request end.
For object UE, reason owing to the charging policy, when object UE is roamed out the home service district, when the request end is initiated the location information request of object UE, after the LCS system provides the positional information of object UE to the request end, object UE need be paid wandering fee in full or part wandering fee to this location service, so object UE may not wish to provide self positional information to the request end being in when roaming LCS system.In addition, the positional information of object UE belongs to private information, when object UE did not wish to be in any territorial scope, the LCS system all offered the request end with its positional information, so this object UE wishes that the territorial scope that can obtain its positional information to the request end does some restrictions.According to present location information request handling process; the LCS standard of 3GPP is not done corresponding definition to the territorial scope notion and the handling process thereof of the visit of object UE limit request end; cause object UE allowing the LCS system after the request end provides self-position information; self privacy may can not get protection; and be faced with the danger that needs the payment high cost, make object UE safe permission LCS system provide its positional information to the request end.

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.
The present invention is according to the LCS standard location information processing of request flow process of prior art 3GPP, by the enhancement process of authentication process, realize that the LCS system just provides the demand of the positional information of object UE to authorization requests end according to the requirement of object UE in effective territorial scope.
When object UE and LCS system contract location service, by limited request end, region is provided with the region effective range, make the LCS system when all or part of end of authorization requests provides this object UE positional information, can strengthen restriction according to the signatory region effective range of object UE.Comprise region limited request end sign in the object UE CAMEL-Subscription-Information of H-GMLC storage and identify corresponding effective territorial scope with limited request end, this region, effectively territorial scope provides effective territorial scope of object UE positional information for object UE allows the LCS system to limited request end, certain region, promptly only work as object UE and be positioned at a certain effective territorial scope, corresponding region limit request end can obtain the positional information of object UE.Limited request end, region is meant that object UE carried out the request end of having authorized of restriction to its territorial scope that obtains the object UE positional information.
The location information request that initiate object UE the request end is received by the LCS system, handle in this location information request process, after H-GMLC obtains the address information of the current place CN of object UE, according to the request end sign and the sign list of storing the limited request end, region in the CAMEL-Subscription-Information of initiating the location service request, judge whether this request end is limited request end, region, if this request end is limited request end, region, judge according to corresponding effective region, limited request end, this region limited field whether the address information of the current place CN of object UE belongs in effective territorial scope, if belong to, carry out subsequent treatment, otherwise, to this request end restoring to normal position failed message, carry the error cause value in this location failed message, refusal provides the positional information of object UE to the request end; If this request end is limited request end, non-region, carry out subsequent treatment.
In addition, receive the object UE positional information of V-GMLC forwarding as H-GMLC after, also can identify and the object UE positional information, further judge whether to provide the positional information of object UE to the request end according to the sign list of the limited request end, region in the CAMEL-Subscription-Information of storage and with the single-phase corresponding effective territorial scope of request end identification name, request end.
Fig. 3 is according to the flow chart of request end of the present invention initiation to the object UE location information request, as shown in Figure 3, initiates the implementation procedure of object UE location information request be may further comprise the steps according to request end of the present invention:
Step 301～step 304 is basic identical with step 201～step 204.
After step 305:H-GMLC receives LCS Service Request, whether receive in step 304 that according to H-GMLC the address information of V-GMLC and the current place CN of object UE is divided into two kinds of situations, corresponding with step 305a and step 305b respectively.
Step 305a: if H-GMLC does not receive the address information of V-GMLC and the current place CN of object UE in step 304, then the LCS service request of R-GMLC and transmission thereof is carried out authentication, judge whether present networks accepts the location information request of R-GMLC localizing objects UE, H-GMLC judges that according to the object UE CAMEL-Subscription-Information of storage whether the request end is by the object UE mandate simultaneously, for example the authentication information Codeword that the request end provides in object UE CAMEL-Subscription-Information and the LCS service request is consistent, show that then the request end is by the object UE mandate, more than two conditions all satisfy, then authentication success, execution in step 306; Otherwise H-GMLC sends error responses to R-GMLC, and R-GMLC carries the error cause value to this request end restoring to normal position failed message in this location failed message.
After step 305b:H-GMLC receives LCS Service Request, if H-GMLC receives the address information of V-GMLC and the current place CN of object UE in step 304, then after the authentication success, continuation judges according to the sign list of limited request end, region whether this request end is limited request end, region, if be limited request end, non-region, execution in step 309; If be limited request end, region, continue according to judging with the corresponding effective territorial scope in this request end whether the address information of the current place CN of object UE belongs in effective territorial scope, if belong to, execution in step 309, if do not belong to, execution in step 315, H-GMLC returns LCS location service response message (LCS ServiceRequest) to this R-GMLC, carry the error cause value in this response message, refusal provides the positional information of object UE to limited request end, this region.
Step 306～step 307 is basic identical with step 206～step 207.
Step 308: in step 306～step 307, H-GMLC will receive V-GMLC that HLR/HSS returns and the address information of CN.At this moment, H-GMLC judges according to limited request end, region sign list whether this request end is limited request end, region, if be limited request end, non-region, execution in step 309; If be limited request end, region, continue according to judging with the corresponding effective territorial scope in this request end whether the address information of the current place CN of object UE belongs in effective territorial scope, if belong to, execution in step 309, if do not belong to, execution in step 315, H-GMLC returns LCS service response message (LCS Service Request) to R-GMLC, carry the error cause value in this response message, refusal provides the positional information of object UE to limited request end, this region.Because H-GMLC after follow-up acquisition target UE locating result information, can also carry out region restriction authentication in the step 314, then this step can be omitted.
Step 309～step 313 is basic identical with step 208～step 212.
After step 314～step 316:H-GMLC receives LCS Service Response, whether determine needs authentication once more according to the CAMEL-Subscription-Information of object UE, authentication if desired, to providing the object UE locating result information of returning to carry out authentication to the request end, the authentication success, continuation judges according to limited request end, region sign list whether this request end is limited request end, region, if be limited request end, non-region, H-GMLC returns LCS service response message (LCS Service Request) to R-GMLC, carry target UE locating result information in this response message, R-GMLC sends LCS service response message (LCS Service Response), the object UE positional information after conversion is returned in the request end to the request end; If be limited request end, region, continue to judge the object UE current position information whether belong to the corresponding effective territorial scope in limited request end, this region in, if belong to, H-GMLC returns LCS service response message (LCS Service Request) to R-GMLC, carry target UE locating result information in this response message, R-GMLC sends LCS service response message (LCSService Response) to the request end, object UE positional information after conversion is returned in the request end, if do not belong to, H-GMLC returns LCS service response message (LCS Service Request) to V-GMLC, carry the error cause value in this response message, R-GMLC sends LCS service response message (LCS Service Response) to the request end, carry the error cause value in the response message, refusal provides the positional information of object UE to limited request end, region; Failed authentication, H-GMLC sends error responses to R-GMLC, and R-GMLC carries the error cause value to this request end restoring to normal position failed message in this location failed message.If do not need authentication, H-GMLC directly returns LCS service response message (LCS Service Request) to R-GMLC, carry target UE locating result information in this response message, R-GMLC sends LCS service response message (LCS Service Response), the object UE positional information after conversion is returned in the request end to the request end.
The location information request that initiate object UE the request end can be 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.
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.
Effective territorial scope of limited request end, region can be the home service district, promptly have only when object UE is positioned at the home service district, just allow the LCS system that the positional information of this object UE is provided to this request end, limited request end, this region is to the immediately type location information request of LCS system initiation to object UE, after H-GMLC obtains the address information of the current place CN of object UE, if object UE is positioned at the home service district, the address information that is CN is positioned at territory scope effectively, the LCS system positions object UE immediately, and the positional information of object UE is provided to limited request end, this region; If object UE is positioned at outside the home service district, promptly the address information of CN does not belong in effective territorial scope, and the LCS system is to limited request end, this region restoring to normal position failed message, and refusal provides the positional information of object UE to limited request end, this region.
Limited request end, region is to the delaying type position information request of LCS system initiation to object UE, postponing Event triggered LCS system positions object UE, for example, limited request end, region request target UE is in case just position it immediately attached to LCS system on the network, when object UE request access network, triggered the incident location condition, the LCS system positions object UE immediately, finish in the CN location, and after the positional information of object UE is transmitted to H-GMLC via V-GMLC, H-GMLC need further carry out region restriction authentication, if the positional information of object UE is positioned at the home service district, the positional information that is object UE belongs in effective territorial scope of this region limit request end, and the LCS system returns the positional information of object UE to limited request end, this region; If object UE is positioned at outside the home service district, the positional information that is object UE does not belong in effective territorial scope of this region limit request end, the LCS system is to limited request end, this region restoring to normal position failed message, and refusal provides the positional information of object UE to limited request end, this region.
It is very flexible that object UE reaches being provided with of the effective territorial scope corresponding with it to limited request end, region, and the LCS system supports the multiple situation that is provided with, and illustrates below.
When object UE and LCS system contract location service, can be set to limited request end, region by all or part of end of authorization requests, and to allowing the LCS system to provide effective territorial scope of this object UE positional information to unify to be provided with to limited request end, region,, be consistent promptly with its corresponding effective territorial scope at limited request end, all regions.For example, it is effective that effective territorial scope of all limited request ends, region is set to when object UE is positioned at the home service district location service request, promptly when object UE is positioned at the home service district, allow the LCS system that the positional information of this object UE is provided to limited request end, region; When it roamed out the home service district, LCS system refusal provided the positional information of this object UE to limited request end, region.
When object UE and LCS system contract location service, can be set to limited request end, region by all or part of end of authorization requests, and to allowing the LCS system to provide the region limited field of this object UE positional information to be provided with respectively to limited request end, region, for example, when object UE is positioned at regionally 1 the time, allow the LCS system that the positional information of this object UE is provided to the limited request end A in region; When object UE is positioned at area 2 or regional 3 time, allow the LCS system that the positional information of this object UE is provided to the limited request end B in region.For example, when object UE is positioned at regional 2 the time, limited request end A in region and the limited request end B in region initiate the location information request of type immediately to object UE respectively, after H-GMLC obtains the address information of the current place CN of object UE, it is inconsistent that the address information of CN does not belong to effective territorial scope of the limited request end A in region, the LCS system is to limited request end, region A restoring to normal position failed message, and refusal provides the positional information of object UE to the limited request end A in region; The address information of CN belongs in effective territorial scope of the limited request end B in region, and the LCS system positions object UE immediately, and the positional information of object UE is provided to the limited request end B in region.
When object UE and LCS system contract location service, also the authentication information for authorization requests end distribution can be combined with effective territorial scope of this limited request end, region, for example, for request end A, for the authentication information of its distribution is Codeword1, the effective territorial scope corresponding with this Codeword1 is area 1 and area 4, promptly is positioned at area 1 or regional 4 time when object UE, and permission LCS system provides the positional information of this object UE to the limited request end A in region; For request end B, for the authentication information of its distribution is Codeword2, the effective territorial scope corresponding with this Codeword2 is area 2 and area 3, promptly is positioned at area 2 or regional 3 time when object UE, and permission LCS system provides the positional information of this object UE to the limited request end B in region.Like this, object UE is to the different region limited field of authentication information definition of different limited request ends.Comprise in the object UE CAMEL-Subscription-Information of storing among the H-GMLC limited request end, region sign list, authorize limited request end, region authentication information and with the corresponding effective territorial scope of limited request end, this region authentication information.During the location information request object UE initiated in LCS system handles request end, H-GMLC judges according to limited request end, region sign list whether this request end is limited request end, region, if be limited request end, non-region, the LCS system positions object UE, and the positional information of object UE is provided to this request end; If be limited request end, region, whether the address information of then judging the current place CN of object UE belongs in the corresponding effective territorial scope of authorization message that limited request end, this region provides, if belong to, the LCS system positions object UE, and provide the positional information of object UE to limited request end, this region, if do not belong to, to limited request end, this region restoring to normal position failed message, carry the error cause value in this location failed message, refusal provides the positional information of object UE to this limited request end.Also can be after H-GMLC receives the object UE locating result information of V-GMLC forwarding, H-GMLC further judges whether to provide to the request end positional information of object UE according to effective territorial scope of the limited request end of positional information and region of the object UE that obtains, processing procedure and said process are basic identical.
Owing to be that effective territorial scope of limited request end, region and the address information of the current place CN of object UE and the positional information of object UE are compared, must effective territorial scope is unified mutually with the method for expressing of the positional information of CN address information and object UE, therefore be that the LCS system can convert this effective territorial scope to the mutually unified geographic range of method for expressing with CN address information and object UE positional information after its effective territorial scope had been determined in limited request end, region in object UE.
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.
