The method of the present embodiment can be used for completing the processing of mobile management net element shown in embodiment five, realization principle Similar with technical effect, details are not described herein again.
Figure 14 is the signaling diagram of the method for the paging UE that the embodiment of the present invention 14 provides, as shown in figure 14, the present embodiment Method may comprise steps of:
Step 901, UE carry out combined registering in the ps domain of EPS network and the CS of 2G/3G network.
It is the prior art that UE, which carries out combined registering in the ps domain of EPS network and the CS of 2G/3G network, and which is not described herein again.
Step 902, registration MME break down.
Registration MME refers to the MME registered when UE combined registering.
Step 903, MSC/VLR break down.
Step 904, MSC/VLR receive downlink CS service request.
Step 905, MSC/VLR select the substitution MME of registration MME in same MME resource pool, and substitution MME can be just Often service is provided for the UE.
Step 906, MSC/VLR send paging request message to substitution MME, and the position of UE is carried in the paging request message The identity of information and UE.
After the registration MME of UE breaks down, if network support selection substitution from same MME resource pool (MME Pool) MME carries out downlink CS business, then service can be provided as the UE by one being selected in resource pool of the MSC/VLR where registering MME Substitution MME, to substitution MME send paging request message.If MSC/VLR can get the location information of UE, asked in paging Seek the location information that UE is carried in message.MSC/VLR is after sending the SGs paging request, starting paging timer.It needs to illustrate , after MSC/VLR failure, in the paging request for issuing substitution MME, still carry the identity of MSC/VLR itself With the identity of UE.
After MSC failure, although MSC may lose the location information of the UE of itself preservation, still there is other way to make The location information that MSC after obtaining failure can get UE typically has following two ways:
(1) home location register (Home Location Register, abbreviation HLR) is by the location information of the UE of preservation It is sent to MSC.
When UE is registered to MSC, MSC can initiate more new position request to HLR while saving the location information of UE, Realize the registration of MSC to HLR, the location information (such as LAI) of UE can be reported to HLR by MSC, and HLR saves the UE that MSC is reported Paging domain (Paging Area) of the location information as UE.It is subsequent downlink CS business initiate during, HLR is being received To after the transmission routing iinformation SRI request that called network element MSC is sent, need to send the PRN that Provides Roaming Number to called MS C Request, to request the roaming number of called UE.If preserving the paging domain of UE on HLR, HLR is providing roaming number to MSC The paging domain of UE is carried in code request, MSC knows LAI from the paging domain.It should be noted that saving seeking for UE on HLR Region is exhaled, exactly carries out calling optimization to MSC to provide paging domain in PRN due to not knowing the LAI of UE after MSC failure ?.
(2) MSC obtains the location information of UE from Backup Data.
In order to improve the disaster tolerance and robustness of equipment, it will usually be carried out to the contextual information of the UE in MSC standby in real time Part, therefore after MSC failure, if the UE location information saved is lost, MSC can still obtain UE location information from Backup Data.
Step 907, substitution MME initiate to eat dishes without rice or wine to page in the corresponding region of location information of UE.
Substitution MME is after the paging request for receiving MSC/VLR transmission, in the corresponding region of the location information of entrained UE Interior initiation eats dishes without rice or wine to page to UE, so as to avoid the whole network paging.
Step 908, substitution MME send paging message to UE.
In view of the contextual information of the not no UE of the substitution MME in MME resource pool, show that the UE is also in ps domain (Deregistered) state of registration or separation (Detach) state, therefore MME initiates paging using the IMSI of UE, and by core net The domain (Core Network, abbreviation CN) is set as " PS ".UE initiates joint attachment flow after receiving the paging, realizes and arrives EPC The combined registering of network PS field and the domain 2G/3G network C S.
Step 909, UE carry out joint note process.
The method of the present embodiment, after the MSC and MME failure that UE is registered, when MSC receives downlink CS business, MSC It selects that the substitution MME of service can be provided as the UE with registering in the same resource pool of MME for UE for UE, and can get In the case where the location information of UE, to substitution MME send paging request in carry UE location information, substitution MME according to be somebody's turn to do After the location information of UE, the paging for arriving the UE is initiated, in the corresponding region of location information of the UE so as to avoid existing skill The problem of art MME initiates the whole network paging or refuses the paging request.
