Background technology
Mobile location service in the Radio Network System more and more is subjected to paying close attention to widely.The main application of mobile location service includes: the emergency calling position service that is used for user security; The location is followed the tracks of and is used; Individual's positioning service (for example inquiry of service industry such as traffic, lodging information); Intelligent transportation transportation location; The design of Radio Network System and resource management; Be used for the charging (determining the communication cost of some position according to calling rate) of Radio Network System etc.
The request type of the positioning service that defines among the 3GPP has position requests and two types of time-delay position requests immediately, for the time-delay location, and just is divided into again in standardized time-delay locating events type:
1) incident that can use of UE
2) incident of regional change type
3) the time-delay locating events of period type.
In the SUPL standard of OMA the cycle is defined as the independently positioning service type of another kind that is independent of immediately outside the location of locating, delay time.

Specific embodiments of the invention are described below.
The cycle localization method that the present invention proposes is meant for the same user of being positioned, when cycle for this user of having carried out among the mobile network once during position fixing process 1, Gateway Mobile Location Center (GMLC) side receives the new period position request 2 for same user again, if can substitute the period interval time parameter of ongoing cycle position fixing process 1 with the cycle position fixing process of new modification period interval time parameter is provided with, can be as well as possible satisfy simultaneous a plurality of cycle Location Request, the blanking time (if necessary, needing to revise the number of times that reports of ongoing position message simultaneously) that then only needs the position message of the ongoing cycle position fixing process of modification.After adopting the mode of modification cycle align_type, just do not need GMLC to stop ongoing cycle position fixing process earlier, and then initiate new cycle position fixing process again, to reach the purpose of the optimization that improves system handles efficient.
The method of revising the cycle parameter of ongoing cycle position fixing process is, increases a kind of event type " periodic modify " in locating request message, and the cycle parameter of locating request message is provided with according to amended parameter then.
The mode that is provided with on UE for cycle timer is for example made amendment in Non-Access Stratum (NAS) interface message of as described in Figure 3 Lg, SGSN/MSC and UE; The mode that is provided with on RNC for cycle timer is for example made amendment in the interface message of as described in Figure 3 Lg, SGSN/MSC and UE, Iu interface message; For example go up the mode that is provided with at professional mobile positioning center (SAS, StandAlone SMLC) independently, in the interface message of as described in Figure 3 Lg, SGSN/MSC and UE, make amendment, make amendment among the Iu, Iupc interface message for cycle timer.Certainly do not get rid of the modification in other locating request message that to pass through yet.
The cycle relevant information that comprises in the cycle positioning service request message of each interface of existing 3GPP protocol definition has:
1) request event type: (stop Periodic) type of (periodic) type of cycle location, dwelling period location;
2) cycle parameter information: the blanking time of position message, position message report number of times.
Adopt after the present invention, the cycle relevant information that comprises in the cycle positioning service request is:
1) request event type: cycle location (periodic) type, dwelling period location (stopPeriodic) type, modification cycle location (modify periodic) type (promptly revising the cycle positional parameter);
2) cycle parameter information: the blanking time of position message, position message report number of times.
Below in conjunction with the applicating example of Fig. 4 by WCDMA application scenarios of the present invention is described:
The framework map of positioning service as shown in Figure 3, when Gateway Mobile Location Center (GMLC) receives that the event type from location-based service agency (LCS client) is the locating request message R1 of ' cycle location ', this moment, GMLC judged the cycle position fixing process for the identical user that is positioned that is not carrying out also not having end at this moment, and be P1 the blanking time of the periodic location reporting in the QOS parameter in this time Location Request, the report reporting number of times is N1, and then the cycle parameter of GMLC initiation R1 request as shown in Figure 4 is the position fixing process of P1 and N1.
If when the cycle position fixing process of R1 request was not finishing, GMLC received the new cycle Location Request R2 from LCS Client again, GMLC can judge and have two cycle Location Requests simultaneously this moment,
If the priority of new cycle Location Request R2 is higher than the priority of ongoing cycle Location Request R1, then GMLC directly initiates the Location Request in modification cycle to follow-up network element, event type is " modification cycle (periodic modify) " in the locating request message, and the parameter of asking in the cycle Location Request of cycle parameter (blanking time of position message and position message report number of times) according to R2 is provided with.The position fixing process that still has been untreated for R1, the cycle timer of R1 request can be set on GMLC, when being timed to, report the requesting party of R1 according to the positioning result of the last R2 as the positioning result of R1, up to the report number of times of finishing the R1 request.Or the number of times of R2 request is initiated the Location Request in modification cycle after finishing again, revise that event type is " periodic modify " in the Location Request of type this moment, the blanking time of cycle parameter, the report number of times was provided with according to the number of times that residue R1 need report according to being provided with the blanking time in the R1 request message; Perhaps GMLC directly locatees end reporting period to the requesting party of R1, no longer continues to provide the position message result to the requesting party.
If the priority of new cycle Location Request R2 is identical with the priority of the R1 that positions process, then be P2 the blanking time of the periodic location reporting in the QOS parameter in the R2 Location Request, and the number of times that reports of position message is N2.And or required precision identical with the required precision of the cycle position fixing process of ongoing R1 can be handled with following flow process more accurately the time.
If P1＞P2, then the GMLC side number of times that reports that need notify thereafter each network element to revise periodic location reporting is P2.
Above some processing that may exist application in the present invention are described, the present invention includes but be not limited to top described.
Realize the cycle position fixing process of the Location Request of Mobile Termination (MT) in chain of command mode among the WCDMA of 3GPP definition, and the locating periodically timer is arranged at one on RNC cycle position fixing process that completes successfully and illustrates.GMLC receives the cycle Location Request R1 from LCSClient, and the R1 information setting is as shown in the table.

After GMLC receives cycle Location Request R1, as shown in Figure 4, execution cycle positioning flow (Figure 4 shows that the flow process that realizes existing 3GPP normal cycle location), detailed steps is as described below.
Step 1, GMLC receives the cycle Location Request from LCS client in 401 processes, after GMLC has carried out flow processs such as normal information judgement, if determine that the user of current cycle Location Request does not have other direct position fixing process of existence or the cycle position fixing process of existence carries out, then GMLC initiates the cycle position fixing process for this user that is positioned.
Step 2, in 402 processes, GMLC sends the cycle Location Request to the MSC/SGSN of correspondence, blanking time, 10 position messages of having periodic event type, 2 minutes position messages in the cycle Location Request report number of times, MSC/SGSN carries out corresponding processing procedure after receiving the cycle Location Request, begin then and UE between carry out normal positioning service correlated process such as paging, authentication and notice, as Fig. 4 403 shown in process; 403 processes complete successfully, and then MSC/SGSN can be to the subsequent cycle of network element initiation afterwards position fixing process.
Step 3, MSC/SGSN is in 404 and 405 processes shown in Figure 4, execution cycle positioning service message call is mutual, after receiving 405 response message, return 406 cycle location response message to GMLC, GMLC continues not have the object information of location in the response message of this moment to the requesting party LCS of R1 Client restoring to normal position service response.
Step 4, MSC/SGSN carries out relevant Non-Access Stratum (NAS) message of positioning service mutual in 408 processes, after completing successfully, the NAS message from UE that MSC/SGSN receives by 405 processes " the cycle positioning service is called and replied " need to determine notice RNC to remove to continue this time cycle position fixing process.
Step 5, shown in 408 processes of Fig. 4, MSC/SGSN sends the cycle Location Request to RNC, and be that 2 minutes, the number of times that reports of position message are 10 times the blanking time of assigned address report in the cycle Location Request.RNC receives the cycle positioning request information content of receiving in back storage 408 processes.
Step 6, RNC is provided with 2 minutes cycle intervalometer, when being timed to, goes to carry out 410 location-independent process, and RNC obtains positioning result according to 410 processes, sends to MSC/SGSN by 411 positioning results, carries out 412 positioned update process then.After MSC/SGSN receives the locating result information of RNC, by 412 processes locating result information is sent to GMLC, GMLC sends to LCS client to locating result information by 413 processes again.
The process of repeating step 6, up to finish specify the positioning result report number of times to report after, finish this time cycle position fixing process.
Below in conjunction with the position fixing process of describing modification cycle parameter shown in the present as Fig. 5.
Step 1, GMLC is after receiving 10 seconds of R1, GMLC receives the cycle Location Request R2 from LCS client in 501 processes, this moment GMLC judge in 502 processes can be with satisfied simultaneously two class Location Requests of minor cycle more, then pass through the cycle parameter of the cycle position fixing process of the ongoing R1 of modification, satisfy the position fixing process of R1 and R2 simultaneously.
Step 2, GMLC sends the cycle Location Request by 503 processes to MSC/SGSN, and the event type of this request is the modification cycle, and be 30 seconds the blanking time of position message, and the number of times that reports of position message is 60 times.
Step 3, MSC/SGSN has received the request from GMLC in 503 processes, in 504 processes, judge now to have had a cycle position fixing process of carrying out, then accept the cycle Location Request that period type is revised in this time, carry out 505 corresponding process such as authentication notice then.
Step 4, MSC/SGSN sends the cycle positioning service by 506 to UE and calls, and it is the modification cycle that event type is set in this message, and be 30 seconds the blanking time that position message is set in cycle parameter is provided with, and the number of times that reports of position message is 60 times.507 processes are received the successful respond message of UE, carry out 510 NAS positioning service correlated process then, and in 508, send cycle location response message to GMLC, after GMLC receives, send the Location Request response message of 509 processes to the requesting party of R2, do not have locating result information in this response message.
Step 5, MSC/SGSN judges that according to the response result of 507 processes the position fixing process needs that will continue the cycle of revising send the locating request message in modification cycle to RNC, 511 processes of then carrying out send locating request message to RNC, type of event parameter in the request message is set to revise period type, be set to 30 seconds the blanking time of position message in the cycle parameter, and the number of times that reports of position message is set to 60 times.
