Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of circuit switched domain service and return legacy network processing (CSFB, CS fallback) Idle state saving signaling (ISR, Idle mode signalingreduction) processing method, Apparatus and system under the scene.
Background technology
Grouping system (EPS in evolution, Evolved Packet System) in the network, as subscriber equipment (UE, User Equipment) prepares to initiate circuit switching (CS, Circuit Switched) the territory beginning is exhaled (MO, when Mobile Originating) professional, UE need forward GPRS (GPRS earlier to, General Packet Radio Service)/universal mobile telecommunications system (UMTS, Universal Mobile Telecommunications System) network, select the sub-district of a 2G/3G to be stationed, and then carry out the MO business.As (the MSC of mobile switching centre, Mobile SwitchCenter) receives and exhale (MT an end, when Mobile Terminated) professional, MSC sends beep-page message by the SGs interface between MSC and the mobile management entity (MME, Mobility Management Entity) to MME, and MME carries out paging by the EPS network to UE, after UE receives this beep-page message, need forward the GPRS/UMTS network earlier to, select the sub-district of a 2G/3G to be stationed, and then finish the subsequent treatment of this MT business.The above-mentioned network architecture and method for processing business are called " CSFB ".In CSFB mechanism, the SGs association is the UMTS Terrestrial radio access network (E-UTRAN that UE resides in evolution, Evolved UMTS Territorial Radio Access Network) sets up the time, for example, UE sets up described SGs association or the like in the tracing section updating flow process (Combined TAU Procedure) of E-UTRAN network initiation associating.
Idle state saving signaling (ISR, Idle mode signaling reduction) also is referred to as saving signaling or limitation signaling function under the idle pulley, and it mainly is the mobile management flow process of UE between different access networks that reduces under the idle pulley.
In the principle that activates ISR under the CSFB scene be at present: need to keep the SGs association between MME and the MSC, just, under the scene of CSFB, if the SGs association is released, the necessary deexcitation of ISR so, the scene that wherein causes the SGs interface to discharge includes but not limited to: UE is at GSM EDGE Radio Access Network (GERAN, GSM EDGE Radio Access Network-)/UMTS Terrestrial radio access network (UTRAN, UMTS Territorial Radio Access Network) network is carried out independent location area updating (LAU, Location Area Update) flow process, perhaps UE carries out related being released of SGs that Routing Area Update (RAU, Routing Area the Update)/LAU flow process etc. of uniting all can cause MSC and MME to set up.The prerequisite of the scene that the above-mentioned SGs of causing interface discharges is to have set up the SGs association between MME and the MSC.
Carry out in the independent RAU flowchart process at UE, UE sends RAU Request message to Serving GPRS Support Node (SGSN, Serving GPRS Support Node), carry CSFBcapability indication in the message, this moment, SGSN can't confirm whether the SGs association can be released.Therefore SGSN can't accurately make the decision that whether activates ISR, if SGSN this moment selects not activate ISR, then may influence the performance of ISR under the CSFB scene, for example, if the SGs association is not released, its actual conditions are can continue to keep ISR to be in state of activation; And if this moment, SGSN selected to activate ISR, then may cause the interruption of CS territory business, influence user's business experience, for example, under the CSFB scene, SGSN selects to continue to keep ISR, UE accepts ISR and activates indication, the follow-up UE that works as returns the E-UTRAN network, and according to the principle of ISR, Idle state UE can not trigger the tracing section updating flow process (Combined TAUProcedure) of associating.This time is if MSC receives the called service in a CS territory, because the SGs association is released, MSC can only be at GERAN/UTRAN ICQ UE, but the current E-UTRAN network that resides in of UE can't receive the beep-page message of MSC, finally cause paging failure, Circuit Service interrupts.
Can find that from top analysis under the CSFB scene, when the independent RAU flow process of UE execution, SGSN can't judge whether to activate ISR accurately, has a strong impact on user's business experience, comprises the performance that influences ISR or causes CS service disconnection etc.

For further understanding embodiments of the invention, with specific embodiment ISR processing method under the described CSFB scene of embodiments of the invention is elaborated below.
Example one: SGSN obtains the former route of UE district information from the UE contextual information that preserve this locality, further obtain UE original position district information, as shown in Figure 2, comprises the steps:
Step 20:UE sends Routing Area Update request message RAU Request;
Can comprise CSFB capability indication in the message; If finished UE to the adhering to of SGSN, and in sending to the Attach Request message of SGSN, comprised CSFB capabilityindication, then can select not comprise CSFB capability indication among the RAU Request before.SGSN is kept at it in contextual information of UE after receiving described CSFB capability indication.
Step 21: base station sub-system (BSS, Base Station Subsystem, comprise BSC and BTS)/RNS (RNS, Radio Network Subsystem) the RAURequest message of transmitting described UE transmission provides the current route of described UE district information Current RAI to SGSN simultaneously to SGSN;
Step 22:SGSN obtains the former route of described UE district information Old RAI from the described UE contextual information that preserve this locality, and obtains original position district information Old LAI relevant with described UE and present position-region information Current LAI according to described Old RAI with the current route of the described UE district information Current RAI that access network equipment provides;
When UE finishes registration (Attach flow process) at network (GERAN/UTRAN), SGSN is that UE creates context, needs to preserve the current route district information of UE in the described UE context, for example, and RAI information.Described RAI information is the current resident route district information of UE that network is preserved, and is provided by access network equipment.Follow-up, when UE carried out the Routing Area Update flow process, access network equipment provided the current route of UE district information to SGSN, Current RAI, and the UE positional information of preserving in the SGSN context belongs to Old RAI information.When finishing the Routing Area Update flow process, Current RAI information replaces the current route district information that Old RAI information becomes the UE that preserves in the UE context.
If SGSN obtains to include in the RAU Request message CSFB capability indication or obtain CSFB capability indication from the UE contextual information of preserving, then SGSN need confirm Location Area Identification (LAI, Location Area Identity) whether changes, judge just whether the lane place changes.
Because Routing Area Identifier (RAI, Routing Area Identity) relevant relation with LAI, the coded format of general RAI is RAI=MCC+MNC+RAC+LAC, and the coded format of LAI is LAI=MCC+MNC+LAC, be to comprise LAI information in the RAI information, then SGSN is by former route district (Old RAI) information and access network equipment in the UE contextual information of preserving, and the Current RAI that provides as BSS/RNS can obtain Old LAI information relevant with UE and Current LAI information;
In addition, do not preserve CSFB capabilityindication if comprise in the RAU Request message among all embodiment of the present invention in the contextual information of CSFBcapability indication or UE, then the SGSN behavior that activates ISR does not need to confirm whether LAI changes.
Step 23:SGSN comparison Old LAI and Current LAI confirm whether LAI changes;
By Old LAI information and the comparison of Current LAI information, SGSN can confirm whether UE present located LAI changes, that is, if Old LAI information is consistent with Current LAI information, expression UE present located LAI does not change; If Old LAI information and Current LAI information inconsistency represent that then UE present located LAI changes.
Step 24:SGSN replys Routing Area Update to UE and accepts message RAU Accept, and selects whether to carry ISR according to judged result and activate indication;
Concrete: if LAI changes, then the SGSN Routing Area Update of replying to UE is accepted the indication information that do not comprise among the message RAUAccept that ISR activates, UE receives described Routing Area Update and accepts to know the ISR deexcitation behind the message RAUAccept, perhaps, if LAI changes, then SGSN accepts to comprise the indication information of representing that ISR does not activate among the message RAU Accept that to the Routing Area Update of UE answer UE receives described Routing Area Update and accepts to know the ISR deexcitation behind the message RAU Accept.
If LAI does not change, SGSN accepts message RAU Accept to the Routing Area Update that UE replys, can comprise the indication information that ISR activates in the RAU Accept message, UE receives described Routing Area Update and accepts RAU Accept message, activate indication information if carried ISR in the message, UE is known can activate ISR.
The embodiment of the invention is after definite UE activates CSFB, judge whether the UE location area information changes, whether change according to the lane place of UE and accurately to judge whether to activate ISR, solved under the CSFB scene, when UE initiates independent RAU, whether the accurate decision-making of SGSN activates the problem of ISR, has promoted the performance of ISR under the CSFB scene, and has guaranteed user's business experience.
Example two: UE comprises the former route of described UE district information in the Routing Area Update request message that sends, SGSN obtains the former route of described UE district information from this Routing Area Update request message, further obtain described UE original position district information, as shown in Figure 3, comprise the steps:
Step 30:UE sends Routing Area Update request message RAU Request, comprises the former route of described UE district information Old RAI among the described Routing Area Update request message RAU Request;
Can comprise CSFB capability indication in the message; If finished UE to the adhering to of SGSN, and in sending to the Attach Request message of SGSN, comprised CSFB capabilityindication, then can select not comprise CSFB capability indication among the RAU Request before.SGSN is kept at it in contextual information of described UE after receiving described CSFB capability indication.
Step 31:BSS/RNS transmits the RAU Request message of described UE transmission to SGSN, provides the current route of UE district information Current RAI to SGSN simultaneously;
Step 32:SGSN can obtain Old LAI information relevant with UE and Current LAI information by the Old RAI information that described UE provides with the CurrentRAI information that BSS/RNS provides;
If SGSN obtains to include in the RAU Request message CSFB capability indication or obtain CSFB capability indication from the UE contextual information of preserving, then SGSN need confirm whether LAI changes, and judges just whether the lane place changes.
Step 33: comparison Old LAI information and Current LAI information, confirm whether UE present located LAI changes.
By comparison Old LAI information and Current LAI information, can confirm whether UE present located LAI changes; That is, if Old LAI information is consistent with Current LAI information, expression UE present located LAI does not change; If Old LAI information and Current LAI information inconsistency represent that then UE present located LAI changes;
Step 34:SGSN replys Routing Area Update to UE and accepts message RAU Accept, and selects whether to carry ISR according to judged result and activate indication;
Concrete: if LAI changes, then the SGSN Routing Area Update of replying to UE is accepted the indication information that do not comprise among the message RAUAccept that ISR activates, UE receives described Routing Area Update and accepts to know the ISR deexcitation behind the message RAUAccept, perhaps, if LAI changes, then SGSN accepts to comprise the indication information of representing that ISR does not activate among the message RAU Accept that to the Routing Area Update of UE answer UE receives described Routing Area Update and accepts to know the ISR deexcitation behind the message RAU Accept.。
If LAI does not change, SGSN accepts message RAU Accept to the Routing Area Update that UE replys, can comprise the indication information that ISR activates in the RAU Accept message, UE receives described Routing Area Update and accepts RAU Accept message, activate indication information if carried ISR in the message, UE is known can activate ISR.
The embodiment of the invention is after definite UE activates CSFB, judge whether the UE location area information changes, whether change according to the lane place of UE and accurately to judge whether to activate ISR, solved under the CSFB scene, when UE initiates independent RAU, whether the accurate decision-making of SGSN activates the problem of ISR, has promoted the performance of ISR under the CSFB scene, and has guaranteed user's business experience.
Example three: the SGSN MME related with setting up ISR obtains the UE present position-region information alternately, as shown in Figure 4, comprises the steps:
Step 40:UE sends Routing Area Update request message RAU Request;
Can comprise CSFB capability indication in the message; If finished UE to the adhering to of SGSN, and in sending to the Attach Request message of SGSN, comprised CSFB capabilityindication, then can select not comprise CSFB capability indication among the RAU Request before.SGSN is kept at it in contextual information of UE after receiving described CSFB capability indication.
Step 41:BSS/RNS transmits the RAU Request message of described UE transmission to SGSN, provides the current route of UE district information Current RAI to SGSN simultaneously;
Step 42:SGSN sends context request message Context Request to the MME that sets up the ISR association, asks the context of described UE to MME;
If SGSN obtains to include in the RAU Request message CSFB capability indication or obtain CSFB capability indication from the UE contextual information of preserving, then SGSN need confirm whether LAI changes, judge just whether the lane place changes, then SGSN sends context request message to the MME that sets up the ISR association, asks the context of described UE to MME; Under the CSFB scene, include the Old LAI information of UE in the UE contextual information that MME preserves, SGSN can by with the mutual Old LAI information that obtains described UE of MME.
Alternatively, SGSN carries the cell of expression to MME request Old LAI information in the context request message that sends to the MME that sets up the ISR association;
Step 43:MME replys context response information Context Response to SGSN, carries the context of described UE in the message, includes the Old LAI information of described UE in the context of described UE;
After step 44:SGSN receives described UE context and obtains Old LAI information, reply context acknowledgement message Context Ack to MME.
Step 45:SGSN is according to access network equipment, the Current RAI that provides as BSS/RNS can obtain the Current LAI information relevant with UE, by comparison Old LAI information and Current LAI information, SGSN can confirm whether UE present located LAI changes; That is, if Old LAI information is consistent with CurrentLAI information, expression UE present located LAI does not change; If Old LAI information and Current LAI information inconsistency represent that then UE present located LAI changes;
Step 46:SGSN replys Routing Area Update to UE and accepts message RAU Accept, and selects whether to carry ISR according to judged result and activate indication;
Concrete: if LAI changes, then the SGSN Routing Area Update of replying to UE is accepted the indication information that do not comprise among the message RAUAccept that ISR activates, and UE receives described Routing Area Update and accepts to know the ISR deexcitation behind the message RAUAccept.Perhaps, if LAI changes, then SGSN accepts to comprise the indication information of representing that ISR does not activate among the message RAU Accept that to the Routing Area Update of UE answer UE receives described Routing Area Update and accepts to know the ISR deexcitation behind the message RAU Accept.
If LAI does not change, SGSN accepts message RAU Accept to the Routing Area Update that UE replys, can comprise the indication information that ISR activates in the RAU Accept message, UE receives described Routing Area Update and accepts RAU Accept message, activate indication information if carried ISR in the message, UE is known can activate ISR.
The embodiment of the invention is after definite UE activates CSFB, judge whether the UE location area information changes, whether change according to the lane place of UE and accurately to judge whether to activate ISR, solved under the CSFB scene, when UE initiates independent RAU, whether the accurate decision-making of SGSN activates the problem of ISR, has promoted the performance of ISR under the CSFB scene, and has guaranteed user's business experience.
