Description
Technical field
The present invention relates to location technology, be meant a kind of processing method of regional change class 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 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 the self poisoning of object UE; Also can offer communication system 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 the standard of LCS and whole LCS system 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, check whether object UE 103 allows this request end 101 that it is carried out location information request, if the legitimacy authentication of the network 102 of request end 101 by comprising the LCS system, the network 102 that comprises the LCS system provides the positional information of object UE 103 to it; Otherwise the network 102 that comprises the LCS system is refused the location information request of the 101 pairs of object UE 103 in request ends.
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 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 network that comprises the LCS system of asking of request end, H-GMLC is the GMLC in the network that comprises the LCS system that object UE belonged to, V-GMLC is the GMLC in the object UE network that comprises the LCS system of visiting, and R-GMLC, H-GMLC and V-GMLC can be same physical entity.
At present, regional change class location information request and implementation procedure thereof have been defined in the 3GPP standard.Regional change class location information request is meant request end desired target area scope and trigger position reporting event in advance, for example object UE enters, leave or report position message to the request end when being positioned at the desired target area scope, the LCS system is sent to object UE with information such as desired target area scope and trigger position reporting events, information such as object UE storage desired target area scope and trigger position reporting event, start corresponding application simultaneously, when application program monitors the generation of trigger position reporting event, for example object UE enters, leave or be positioned at the desired target area scope, object UE reports position message to the LCS system, the LCS system transmits this position message to the respective request end, and the trigger position reporting event of its appointment of notice respective request end takes place.In addition, but the request end also intended target UE report the number of times of position message to it, for example, only report position message one time, or carry out periodicity in the effective time of appointment in the scope and report.In sum, utilize regional change class location information request, the request end can define some tracing and monitoring class location services easily, and for example, children follow the tracks of, pet is followed the tracks of etc., make location service to be widely used aspect tracing and monitoring.
Because the processing procedure of regional change class location information request relates to V-GMLC and CN and the V-GMLC and the CN that cover desired target area scope of object UE under current, therefore need object UE under current V-GMLC and CN and cover the V-GMLC of desired target area scope and the support that CN handles regional change class location information request.
Fig. 2 is the interacting message figure of regional change class location information request processing procedure in the prior art, and as shown in Figure 2, the interacting message of regional change class location information request processing procedure may further comprise the steps:
Step 201: the request end sends LCS service request (LCS Service Request) to R-GMLC, carry object UE sign, desired target area scope and trigger position reporting event among this LCS Service Request, the trigger position reporting event can be object UE and enters, leaves or report position message when being positioned at the desired target area scope; Go back scope effective time of portability LCS service request among this LCS Service Request, for example zero-time and termination time, and the LCS service request requires to report the number of times of position message, repeatedly report position message if desired, then also need carry the blanking time that periodically reports position message among this LCS Service Request.This LCS Service Request is above-described regional change class location information request.
After step 202:R-GMLC receives LCS Service Request, this request message is forwarded to H-GMLC, H-GMLC carries out the legitimacy authentication is carried out in the request end, determine whether object UE allows the LCS system to provide its positional information to this request end, if the request end is by the legitimacy authentication, then the V-GMLC of H-GMLC under object UE is current sends LCS Service Request; Otherwise H-GMLC returns failed authentication message to R-GMLC, the regional change class location information request that initiate object UE R-GMLC refusal request end, and end region changes class location information request handling process.
Step 203: after the V-GMLC under object UE is current receives LCS Service Request, the desired target area scope of carrying among this LCS Service Request is converted to the ground domain identifier that network can be discerned, and send localizing objects UE request (Provide SubscriberLocation) to the CN of object UE under current, carry desired target area scope and the trigger position reporting event represented with the geographical form of network after object UE sign, the conversion among this Provide Subscriber Location; Corresponding with the information of carrying among the LCS ServiceRequest, go back the number of times that portability reports position message among this Provide Subscriber Location, repeatedly report position message if desired, then carry the blanking time that periodically reports position message.
Step 204: the CN under object UE is current finds that object UE is in idle pulley, then object UE is initiated paging, and object UE is carried out authentication and encryption, determines whether object UE is the legal network user; Further, the CN under object UE is current also can send privacy checking notice to object UE, and notification target UE has its positional information of request end request, verifies whether allow the LCS system to provide its positional information to this request end in person by object UE.
Step 205～step 206: the CN of object UE under current sends band of position incident call request (Location Area Event Invoke) via RAN to object UE, and the information of carrying among the information of carrying among this Location Area EventInvoke and the LCS Service Request is corresponding.After object UE is received Location Area Event Invoke, start the related application of self, the generation of monitoring trigger position reporting event; And send band of position incident to its CN under current and call response message (Location Area Event Invoke Ack), this location service request of notice CN has been accepted and has carried out respective handling.
Step 207～step 210: after the CN under object UE is current receives Location Area Event InvokeAck, V-GMLC under object UE is current sends localizing objects UE response message (ProvideSubscriber Location Ack), and this location service request of notice V-GMLC is accepted.After V-GMLC under object UE is current receives Provide Subscriber Location Ack, send LCS service response message (LCS Service Response) to H-GMLC, this location service request of notice H-GMLC is accepted.After H-GMLC receives LCS Service Response, send LCSService Response to R-GMLC, this location service request of notice R-GMLC is accepted.After R-GMLC receives LCS Service Response, send LCS Service Response to the request end, this location service request of notice request end is accepted by object UE.
Step 211～step 212: the trigger position zone issue takes place, be that object UE enters, leaves or is positioned at the desired target area scope, object UE sends band of position event report message (Location Area Event Report) via RAN to the CN that covers the desired target area scope, and notice CN trigger position zone issue takes place.
Step 213～step 214: after the CN of covering desired target area scope receives Location Area EventReport, send object UE position message message (Subscriber Location Report) to the V-GMLC that covers the desired target area scope, the trigger position zone issue of notice V-GMLC object UE takes place.After the V-GMLC of covering desired target area scope receives Subscriber Location Report, send object UE position message response message (SubscriberLocation Report Ack) to the CN that covers the desired target area scope, notice CN has received the Subscriber Location Report of its transmission, at this moment, CN can be this location service request and generates corresponding ticket writing.
Step 215～step 218: the V-GMLC that covers the desired target area scope is after the CN that covers the desired target area scope sends Subscriber Location Report Ack, send LCS Service Response to H-GMLC, the trigger position zone issue of notice H-GMLC object UE takes place.H-GMLC carries out authentication to the request end after receiving LCS Service Response, guarantees that the positional information of the object UE that provides to the request end belongs within the authority allowed band of this request end.The request end is by after the authentication of H-GMLC, and H-GMLC sends LCS Service Response to R-GMLC, and the trigger position zone issue of notice R-GMLC object UE takes place.After R-GMLC receives LCS ServiceResponse, send LCS Service Response to the request end, the trigger position zone issue of notice request end object UE takes place.
If carried blanking time that periodically reports position message and the number of times that reports position message in the regional change class location information request, then object UE reports position message blanking time to what the CN that covers the desired target area scope reported that the time interval of position message stipulates in can not be less than regional change class location information request, report the total degree of position message can not surpass the number of times that requires in the request, it reports in the processing procedure of position message and the said process step 211～step 218 basic identical at every turn.
Above-described regional change class location information request processing procedure be object UE under current V-GMLC and CN and cover the V-GMLC of desired target area scope and the process of CN when all supporting processing to regional change class location information request.But owing to realize function aspects and to the deficiency of location service tenability, V-GMLC and CN might not support the processing to regional change class location information request.
If the V-GMLC under object UE is current does not support the processing to regional change class location information request, receiving H-GMLC behind the LCS of its transmission Service Request, send the LCS Service Response that carries error cause to H-GMLC; If the CN under object UE is current does not support the processing to regional change class location information request, receiving that the current affiliated V-GMLC of object UE behind the Provide of its transmission Subscriber Location, sends the Provide Subscriber Location Ack that carries error cause to V-GMLC; If the CN of covering desired target area scope does not support the processing to regional change class location information request, receive object UE via RAN behind the Location of its transmission Area Event Report, send the Subscriber Location Report that carries error cause to the V-GMLC that covers the desired target area scope; If the V-GMLC of covering desired target area scope does not support the processing to regional change class location information request, receive the CN that covers the desired target area scope behind the Subscriber of its transmission Location Report, sending the LCS Service Response that carries error cause to H-GMLC; In follow-up process, receive that the functional entity in the LCS system that carries the error cause failed message sends down this failed message.
Especially when the V-GMLC that covers the desired target area scope and CN do not support processing to regional change class location information request, when object UE via RAN after the CN that covers the desired target area scope sends Location Area Event Report, because the V-GMLC of covering desired target area scope or CN can't realize the processing to regional change class location information request at all, can only in subsequent process, send the failed message that carries error cause, receive that the functional entity in the LCS system of this failed message sends down this failed message, like this, when the request end initiated area changes the class location information request, interactive messages all becomes dead message between the functional entity in the LCS system, must cause the LCS resource waste.When particularly object UE need periodically report position message, a large amount of failed messages will occur in the LCS system, the LCS resource waste is particularly outstanding.For the request end, may make that the execution efficient of location service is very low after waiting for for a long time, receiving failed message.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of processing method of regional change class location information request, when avoiding the position service system wasting of resources, improved the execution efficient of location service.

Owing to realize the deficiency of function aspects and tenability, if the V-GMLC under object UE is current does not support the processing to regional change class location information request, after receiving the regional change class location information request of request end, will directly send failed message to H-GMLC, therefore under the prerequisite that the V-GMLC of the present invention under object UE is current can handle regional change class location information request, whether increase can change the process that the class location information request is judged by processing region to the functional entity in the LCS system, if then the LCS system is issued to object UE with regional change class location information request; Otherwise, the LCS system changes class location information request operation failure message to the sending zone, request end, the notice request end is because the functional entity in the LCS system can not change the class location information request by processing region, end region changes class location information request handling process in advance, improve the execution efficient of location service with this, and the LCS system resource waste of avoiding the generation because of a large amount of dead messages to cause.Functional entity in the above-described LCS system comprises: cover the CN of desired target area scope, the V-GMLC that covers the desired target area scope and the object UE CN under current.
Fig. 3 is the process chart of regional change class location information request among the present invention, and as shown in Figure 3, the processing procedure of regional change class location information request may further comprise the steps:
Step 301: the request end changes the class location information request to the R-GMLC sending zone, carry object UE sign, desired target area scope and trigger position reporting event in this regional change class location information request, the trigger position reporting event can be object UE and enters, leaves or report position message when being positioned at the desired target area scope; Go back portability scope effective time in this regional change class location information request, for example zero-time and termination time, and the number of times that reports position message, repeatedly report position message if desired, then also need carry the blanking time that periodically reports position message in this regional change class location information request.
Step 302:R-GMLC receives that the request end is after the regional change class location information request of its transmission, change the class location information request via the V-GMLC sending zone of H-GMLC under object UE is current, carry object UE sign, desired target area scope and trigger position reporting event in this regional change class location information request, the trigger position reporting event can be object UE and enters, leaves or report position message when being positioned at the desired target area scope; Report the number of times of position message, repeatedly report position message if desired, then also need carry the blanking time that periodically reports position message in this regional change class location information request.
Step 303: the V-GMLC under object UE is current judges whether the V-GMLC that covers desired target area supports the processing to regional change class location information request, if, execution in step 304; Otherwise, execution in step 308.V-GMLC under object UE is current can carry out information interaction with the V-GMLC that covers desired target area, according to the message that the V-GMLC that covers desired target area returns, whether definite V-GMLC that covers desired target area supports the processing to regional change class location information request.
Step 304: the V-GMLC under object UE is current judges whether the CN that covers desired target area supports the processing to regional change class location information request, if, execution in step 305; Otherwise, execution in step 308.The V-GMLC of object UE under current judges according to the CN location service disposal ability information of self storage whether the CN of object UE under current supports the processing to regional change class location information request, or according to judging with the information interaction of other V-GMLC whether the current affiliated CN of object UE supports the processing to regional change class location information request; Also can judge whether the current affiliated CN of object UE supports the processing to regional change class location information request by the database server in the query communication network.
Step 305: the V-GMLC under object UE is current judges whether the current affiliated CN of object UE supports the processing to regional change class location information request, if, execution in step 306; Otherwise, execution in step 308.Basic identical described in basis for estimation and the step 304.
Step 306～step 307: the CN sending zone of the V-GMLC under object UE is current under object UE is current changes the class location information request, and this regional change class location information request is correspondingly carried identical content with the regional change class location information request described in the step 302.After CN under object UE is current received regional change class location information request, the LCS system was basic identical to the subsequent treatment processing procedure and the step 204～step 218 of regional change class location information request, finished until regional class location information request handling process.
Step 308～step 309: the V-GMLC under object UE is current sends the regional change class location information request operation failure message of carrying error cause via H-GMLC to R-GMLC; After R-GMLC receives the regional change class location information request operation failure message that carries error cause, send this regional change class location information request operation failure message to the request end, the notice request end is not because the functional entity in the LCS system is supported the processing to regional change class location information request, its regional change class location information request that object UE is initiated is handled failure, end region class location information request handling process.
Can step 303, step 304 and step 305 change the step that the class location information request is judged by processing region for what increase among the present invention to the functional entity in the LCS system, in the process that the LCS system handles regional change class location information request, be not to be necessary procedure, can only comprise step 303 and step 304, can realize that equally the present invention improves the execution efficient of location service, avoid the goal of the invention of the LCS system resource waste that the generation because of a large amount of dead messages causes; Only step 303, step 304 and step 305 mutually combine and can access the better implement effect, have avoided the generation of dead message to greatest extent.In addition, step 305 also can be positioned at before the step 303, promptly first execution in step 305, and then execution in step 303; The order of between step 303 and step 304 is interchangeable also, promptly first execution in step 304, and then execution in step 303.
After V-GMLC under object UE is current receives regional change class location information request, carry out information interaction with the V-GMLC that covers the desired target area scope, require the V-GMLC that covers the desired target area scope that disposal ability information is provided, after the V-GMLC of covering desired target area scope receives the mutual request message of the current affiliated V-GMLC of object UE, judge the processing of self whether supporting regional change class location information request, if do not support, then directly to the current affiliated V-GMLC return error response message of object UE; Otherwise the tenability information that its support area is changed the processing of class location information request is sent to the current affiliated V-GMLC of object UE; The V-GMLC that covers the desired target area scope also can directly handle the disposal ability information of whether supporting with it to regional change class location information request and be sent to the current affiliated V-GMLC of object UE, V-GMLC under object UE is current judges according to the V-GMLC disposal ability information of the covering desired target area scope of receiving whether the V-GMLC that covers the desired target area scope supports the processing to regional change class location information request.
