The application is to be that July 31, application number in 2003 are 03152225.4 and denomination of invention dividing an application for the application of " navigation system " applying date.
Technical field
The present invention relates generally to navigation system, this system is used for providing locating information about mobile subscriber equipment (UE) terminal according to " Functional stage 2 description of LCS (LCS function phases 2 describe) " of the 3GPP in June, 2002 (third generation collaborative project) technical specification 23.271 33-62 page or leaf V.5.3.0 for the client.More specifically, the present invention relates to reusing of known locating information last time.
Background technology
The locating information of mobile UE terminal is responsive for mobile subscriber's privacy usually and when the user was in an emergency situation, described locating information was normally crucial.For the privacy locating information of protecting the mobile subscriber not by unauthorized access, mobile radio communication is provided a senior Privacy Preservation Mechanism, it applies various restrictions according to the privacy overview (when and where) of mobile subscriber's regulation for Location Request.Described Privacy Preservation Mechanism provides for two types of a Location Request examine according to the decision-making function that wherein changes along with a point in the serviced network of described Location Request.When network receives Location Request from a client terminal, on this client terminal, carry out first type examine, be called the client and check.Second type examine is if the place and the time interval of being stipulated by UE terminal use's privacy overview are satisfied, and then grants a permission of giving described Location Request after the locating information of UE terminal is obtained, is called the privacy inspection.
On the other hand, mobile network provider is required also to provide positioning service except their basic mobile communication business.Especially, positioning service relates to several network nodes, and these nodes are intercoursed specific message for the position calculation of an object UE and exchanged messages by Radio Link and target terminal.
The 3GPP positioning information system of stipulating in the 3GPP standard mainly by client terminal, GMLC (Gateway Mobile Location Center), SGSN/MSC (serving general packet radio service support node/move and serve switching center), be called the local wireless network of RAN (radio access network) and constitute via UE (subscriber terminal equipment) terminal that Radio Link is connected to described RAN.HLR/HSS (attaching position register/home subscriber server) is connected to GMLC as the database of the identity that is used to keep the RAN that the UE terminal is connected to.The client terminal of registration is given the patent rights of visit UE terminal.
The 3GPP standard provides two kinds of operator schemes that are used for location request, i.e. Location Request of Mobile Termination (MT-LR) and mobile location request initiating (MO-LR).In the MT-LR pattern, client terminal can or the current location of request target UE or ask the current of this terminal or location that last time is known.When for a certain reason, when network was failed localizing objects UE, if last time, known locating information can be used, then last time, known locating information was replaced current location information and as positioning reporting.
More particularly, when network received Location Request for an object UE, the SGSN/MSC that is responsible for the management of object UE also was responsible for the secret protection of UE terminal.According to the secret protection of the MT-LR pattern of 3GPP standard code, the UE mobile subscriber is registered in their privacy overview (for example being allowed to ask those clients' the identifier of their position) among their SGSN/MSC of internal network.In response to a Location Request, SGSN/MSC examines described Location Request by the registered privacy overview of contrast object UE and carries out the privacy inspection and determine whether this Location Request is licensed.If the privacy overview of a UE terminal is also stipulated a notice that is sent to the UE terminal/examine request, then the UE terminal is given one and is used as the notice of target or examines described Location Request and a verification result is turned back to client terminal.When described Location Request when being acceptable, SGSN/MSC cooperates to continue a location estimation process with relevant RAN, so that determine the prelocalization of working as of object UE.If SGSN/MSC fails to obtain the current locating information of object UE, if then the last time of stored this object UE, known locating information was still available or effective at present, then the last time of stored this object UE known locating information copy be sent to client terminal.
In the MO-LR pattern, mobile UE terminal exclusively ask automatic network its oneself work as prelocalization.In this pattern, the fault in the location survey will cause an error reporting to be sent to the mobile UE terminal of request.Known locating information was not reused and was replaced error reporting to be used for sending last time.
But, there are many shortcomings in the prior art navigation system.
At first, Business Stream by fixer network and location survey amount of calculation increase with Location Request from client and portable terminal with being directly proportional.In addition, the part of fixer network is also shared by mobile radio communication.Therefore, when the fixer network experience weighed business load, mobile communication business may be adversely affected, and this may cause the added burden for mobile network provider.
Secondly, in the MT-LR operator scheme, carry out the privacy inspection by SGSN/MSC.If the reusable last time of UE terminal, known locating information can obtain in GMLC, then for example SGSN/MSC will carry out privacy inspection for the UE terminal.But,, GMLC do not carry out the mechanism that privacy is checked for being provided for asking SGSN/MSC.As a result, had only when last time, known locating information was retained among the GMLC, the secret protection of this locating information just is guaranteed.
The 3rd, the reusability of the locating information that last time is known only depends on SGSN/MSC and whether has kept known locating information last time, and the standard of reusability depends on the detail of SGSN/MSC different between different SGSN/MSC.Therefore, the client terminal of request may receive unworthy last time of known locating information.

The description of preferred embodiment
If GMLC has kept the privacy information of its inner UE terminal, then the MT-LR of local GMLC operation is carried out to the flow process shown in the 12E according to Figure 12 A.
In Figure 12 A, when local GMLC receives from client terminal or comes the message of automatic network, routine is with determination step 201 beginning, and whether check the type of message and source so that determine message is that the Location Request from client terminal, the Location Request of transmitting from another GMLC or message contain the SGSN/MSC identifier from HLR/HSS.If message is the Location Request from client terminal, then flow process proceeds to step 202, thereby so that the privacy overview of the object UE in carrying out client terminal that client checks the request of examining and being kept at local GMLC is consistent.If do not examine Location Request in step 202, then error message terminal (step 223) and routine of being sent to request stops.
If the client of request is verified (step 202) or the message that receives is Location Request (step 201) from another GMLC, then flow process proceeds to step 204, so that determine whether local GMLC is the inside GMLC of object UE.If this is the case, then flow process proceeds to determination step 205, whether is connected to GMLC so that check a PPR (privacy overview register).
If there is not PPR to be connected to local GMLC, then on Location Request, carry out for the first consistent privacy inspection (step 206) of the privacy overview of object UE terminal so that determine whether Location Request is acceptable (step 207).
The first privacy overview of UE terminal can comprise permission/refusal client terminal be acceptable or the accuracy of requested locating information whether be acceptable or requested last time the useful life of known locating information whether be acceptable indication.The first privacy overview can also comprise whether the UE terminal use wants from the notice of client terminal or by the conduct of examining of the UE terminal indication for the standard of the acceptance of Location Request.If UE user wants the notice from the requestor, then UE user will to receive the indication UE terminal of automatic network be the notice of the target of Location Request.If UE user wants to examine, then whether the user will receive the current Location Request of indication of automatic network should received verification message.The UE terminal utilizes an audit report to respond described verification message.
If first privacy is checked step 207 and determines that the Location Request that receives is not acceptable that then flow process proceeds to step 223 and sends the terminal of an error message to request.If Location Request is acceptable, then flow process proceeds to and carries out an inspection on the type of the locating information of step 208 in being included in received Location Request, has stipulated which parameter (C, L, C/L and L/C) (step 209) so that determine in the described request.If the locating information type stated known (L) or " known or current (L/C) locating information last time " last time (wanting last time known locating information to make to it satisfied but current locating information can not obtain) if show client user, then flow process proceeds to step 210, comes to carry out the inspection for reusability in last time on the known locating information.If " useful life and place " demand of requested Location Request meets the privacy overview of object UE, then carry out about last time known locating information whether satisfy the further inspection (step 211) of the demand in the memory that is stored in.
If this last time, known locating information can obtain, then flow process proceeds to step 212, checks so that check that whether the privacy overview of object UE shows that needs are to the notice of object UE or examining by object UE.If this is the case, then flow process proceeds to step 213, sends a query messages is used to ask be responsible for the SGSN/MSC of object UE terminal to HLR/HSS identifier.If do not receive response from HLR/HSS, then an error message is sent to client terminal (step 223).When receiving a response message from HLR/HSS, when (step 214), check that if GMLC proceeds to step 215 its content and response message only contain the SGSN/MSC identifier, then send a notice/verification message to the SGSN/MSC that is identified.If except the SGSN/MSC identifier, also contain the identifier of GMLC from the response message of HLR/HSS, then GMLC will notify/verification message sends to the GMLC that is identified.If the privacy overview of object UE only needs notice (step 216), then flow process proceeds to step 218.Otherwise flow process proceeds to step 217, whether shows that the client terminal of request is verified so that check the audit report from the UE terminal.If the judgement in step 217 is negated that then flow process proceeds to step 223, an error message is sent to the terminal of request.If the judgement in step 217 is sure, then flow process proceeds to step 218, determines whether GMLC is connected to PPR.
If there is not PPR to be connected to GMLC (step 218), then flow process proceeds to step 219 and carry out the second privacy inspection on locating information current or that last time is known, so as the location of determining its location estimation time and its estimation whether with " time zone and the area " parameter consistent (step 220) of the privacy overview of the UE that is allowed to.If the result of the second privacy inspection is disadvantageous (step 220), then an error message is sent to client terminal (step 223).Otherwise if the accuracy of locating information is higher than the accuracy that is allowed to, then locating information is handled (step 221) according to the privacy overview of UE.In step 222, locating information (current or last time known) is sent to client terminal.If being the copy of current and current locating information, locating information is stored in the memory as known locating information last time.
If the UE terminal does not need to notify/examine, then the judgement of step 212 be negate and flow process proceed to step 219, carry out the second privacy inspection, skips steps 214 to 218.
If in the Location Request that receives, stipulated current (C or C/L) locating information (step 209) or last time known locating information can not obtain (step 211), then flow process proceeds to step 231 (Figure 12 B), so that send a query messages is used to ask be responsible for the SGSN/MSC of object UE terminal to inner HLR/HSS identifier.When requested identifier is received (step 232), flow process proceeds to step 233, so as to check the privacy overview of object UE whether show need to notify/examine.If do not need, then Location Request is depended on the current location of object UE and is sent to inside or outside SGSN/MSC, so that obtain its current locating information.When requested current locating information is received (step 235), flow process proceeds to step 218.If not response, then error message is sent to the terminal (step 223) of request.If the judgement in step 233 is sure, then flow process proceeds to step 236, a Location Request and notice/verification request message are depended on the current position of object UE and send to inside or outside SGSN/MSC, be used to receive a response (step 237).If the current locating information and the audit report of object UE are received, then flow process proceeds to step 237 to step 217.If do not receive response, then flow process proceeds to step 233 from step 237, so that send an error message to client terminal.
If the judgement in step 204 shows that local GMLC is not the inside GMLC of object UE, then flow process proceeds to step 241 (Figure 12 C), so that send a query messages to outside HLR/HSS, so that obtain the identifier of an appropriate GMLC, the inside HLR/HSS that described outside HLR/HSS is external object UE.When the identifier of this appropriate GMLC was obtained, a Location Request was sent to the GMLC that is identified, so that obtain the locating information of object UE.If locating information is successfully received, then flow process proceeds to step 222, so that the locating information that receives is forwarded to the terminal of request.If response is not returned, then error message is sent to the terminal (step 223) of request.
If the judgement in the step 201 shows that the message such as notice/verification message, audit report, Location Request or positioning reporting is received from other GMLC, then flow process proceeds to step 251 (Figure 12 D) from step 201, so as with the forwards that receives to the downstream node of discerning by the SGSN/MSC that comprises in the described message (perhaps adding GMLC) identifier.
If a PPR is connected to local GMLC, then the judgement in the step 205 is sure and flow process proceeds to step 224, obtains a report so that send an authorization requests (in order to have or do not have the privacy inspection of locating information type checking) to PPR.If PPR preserves the locating information of portable terminal at execution first privacy inspection and PPR on the Location Request then utilizes the information type inspection of attendant under the situation of the reusability test that the stored information type of object UE is checked in addition.In step 225, GMLC receives the report that shows the first privacy check result and reusability test result from PPR.The report that step 225 analysis receives.If the first privacy check result is favourable and does not carry out reusability test (a) that then flow process proceeds to step 208.Otherwise flow process proceeds to step 223, so that send the terminal of an error message to request.If the result of the first privacy inspection and reusability test is favourable (b), then flow process proceeds to determination step 212.If the first privacy check result is favourable, but the result of reusability test is disadvantageous (c), and then flow process proceeds to step 231 (Figure 12 B).
If the judgement in step 218 is sure, then flow process proceeds to step 261 (Figure 12 E) and sends a request to PPR and be used to ask it to carry out the second privacy inspection.In step 262, the report that shows the second privacy check result is by analyzed from requested PPR reception and result.If the result shows a favourable judgement, then flow process proceeds to step 222 from step 262, the locating information of object UE is sent to the terminal of request.If in step 262, show a mistake from the report of PPR, then flow process proceeds to step 223, sends terminal or the GMLC of an error message to request.
If the privacy information of inner UE terminal is not stored among the local GMLC, then the MT-LR of GMLC operation continues according to the flow chart of Figure 12 F and the inside SGSN/MSC of object UE terminal operates according to the flow chart of Figure 13.
In Figure 12 F, routine is wherein checked the type and the source of this message from step 271 when a message arrives local GMLC.If this message is the Location Request from client terminal, then flow process proceeds to step 272, carries out a client and checks.If client terminal is verified (step 273), then flow process proceeds to step 274 and checks whether so that check local GMLC be the inside GMLC of object UE.If then flow process proceeds to step 231 (Figure 12 B).Otherwise flow process proceeds to step 241 (Figure 12 C).If described message is the Location Request from other GMLC, then step 272,273 is skipped and step 274 is performed.If described message contains a node identifier, then flow process proceeds to step 251 from step 271 and transmits message downstream.
The MT-LR operation of SGSN/MSC of the present invention is described below with reference to the flow chart of Figure 13.
The routine of SGSN/MSC is from receiving or from GMLC or from the message (step 300) of mobile UE terminal.If Location Request is sent from GMLC and SGSN/MSC preserves the privacy overview (step 301) of positioning reporting and UE terminal, then flow process proceeds to step 302, carry out for the consistent privacy inspection of the first privacy overview of object UE.If request is acceptable, then flow process proceeds to the locating information type that step 304 is checked described request.If described request is unacceptable (step 303), then error message is returned to the GMLC (step 315) of request.
If SGSN/MSC does not preserve the positioning reporting and the privacy overview of UE terminal, then flow process proceeds to step 331 and sends a Location Request to RAN and a positioning reporting is forwarded to the GMLC (step 332) of request from RAN.
If the judgement in step 300 shows that described Location Request is sent from a UE terminal, then flow process proceeds to step 304, skips steps 302 and 303.
If the locating information (step 304) that the last time of Location Request define objective UE is known, then a reusability test is provided (step 306,307).If in step 307, the result of reusability test is disadvantageous, and then flow process proceeds to step 308, sends a Location Request to relevant RAN, so that obtain the current locating information (step 308,309) of object UE.If do not receive response, then error message is sent to the source (step 315) of request.
If the judgement in step 307 or 309 is sure, then flow process proceeds to step 310.If received Location Request from GMLC, then flow process proceeds to step 311, carry out for the consistent privacy inspection (step 312) of the second privacy overview of object UE terminal.If the result of privacy inspection is disadvantageous, then error message is returned to the source (step 315) of request.Otherwise flow process advances to step 313, if the accuracy of (or current or last time is known) is higher than the accuracy that is allowed to so that locating information, then handles locating information according to the privacy overview.Then, processed locating information is sent to the source (step 314) of request.If received Location Request from the UE terminal, then flow process proceeds to step 314 from step 310, locating information is sent to the UE terminal of request.
If SGSN/MSC receives the notice/verification message (step 300) from GMLC, then flow process proceeds to step 320, checks so that check and has asked to notify or asked to examine.If asked notice, then flow process proceeds to step 321 and sends a notification message to object UE and termination routine.If be requested by examining of object UE, then flow process proceeds to step 322 and sends a verification message to object UE.In response, the terminal of object UE inspection request and send an audit report to SGSN/MSC.This report is forwarded to the GMLC (step 323) of request by SGSN/MSC.
The MO-LR operation of mobile UE terminal of the present invention is carried out according to flow chart shown in Figure 14.
When the user of UE imports one when asking terminal to be used to ask the locating information of terminal of itself, the routine of mobile UE terminal is from step 401.The request msg of input is stipulated one of locating information type as described above.In step 402, the type of the locating information of UE terminal inspection input and determine to have stipulated which kind of type (step 403).If last time, known locating information was requested, then flow process proceeds to step 404 and determines whether locating information in the past is stored in the memory 1052 (Fig. 2 A) of UE terminal.If the judgement in step 404 is sure, then flow process proceeds to the last time known locating information (step 406) of step 405 for reusability inspection storage.If canned data satisfies the privacy overview of UE terminal, then Cun Chu locating information is confirmed as reusable and canned data is read (step 407) and is displayed on (step 411) on the map.If if the judgement of step 403 shows the judgement when prelocalization or step 404 or 406 of the request regulation UE terminal of input negate, then flow process proceeds to step 408 and sends a Location Request to SGSN/MSC via RAN.In step 409, Location Request is handled in SGSN/MSC and locating information is sent from SGSN/MSC and received by the UE terminal.According to the type of the locating information of stipulating in the locating request message that sends, the current locating information known or this terminal last time of the locating information that receives from SGSN/MSC or the UE terminal of request.In step 410, the memory of UE terminal is utilized the positioning information update of reception and the information of reception is shown (step 411).
