In actual applications, the MSC/VLR in LTE overlay areas can form pond domain (POOL), so on the one hand play
The effect of disaster tolerance, on the other hand can reduce needs to upgrade the MSC/VLR quantity for supporting SGs interfaces.Fig. 4 is the knot of this network
Composition, the wherein RNC in the domain of pond and BSC connect as radio access node with all VLR/MSC in pond.In POOL
VLR/MSC for UE by distributing temporary user identifier (TMSI) to ensure the air interface messages of the UE in RNC and BSC all the time
This MSC/VLR can be routed to.Because TMSI includes network resource identifier (NRI) field, this NRI field is unique in POOL
The sensing MSC/VLR.In the domain of pond, can only have and SGs interfaces are used between part VLR/MSC and MME, initiate to join from MME
The UE of location updating is closed, these VLR/MSC are registered to by co-location renewal process, and distribute and belong to registered VLR/MSC
TMSI, when UE is fallen back in the domain of pond, serviced by TMSI from these VLR/MSC.
When a MSC/VLR in POOL is restarted, the MSC/VLR loses its TMSI information preserved, so
When the MSC/VLR is received into call request, IMSI, rather than TMSI will be used to be paged.Fig. 5 is a MSC/ in POOL
After VLR is restarted, traditional circuit domain UE is received into processing when calling for asking, and comprises the following steps S502 to step S524.
Step S502：GMSC receives initial address message, sends and obtains routing information request to HLR.
Step S504：HLR according to MSC/VLR addresses where the user that is recorded, transmission Provide Roaming Number request to
MSC/VLR, MSC and VLR is physically a network element here.
Step S506：MSC/VLR lost the user data because restarting, and send restoring user data request
To HLR.
Step S508：HLR inserts user data, and MSC/VLR returns to response.
Step S510：MSC/VLR returns to restoring user data response, and returns to roaming number to HLR.
Step S512：HLR, which is returned, obtains routing iinformation response to GMSC, carries roaming number.
Step S514：GMSC uses roaming number, sends initial address message to MSC/VLR.
Step S516：MSC/VLR receives the initial address message sent from GMSC, and user is paged, due to not having
The TMSI of user, so paging uses IMSI to be identified as user.
Step S518：BSC or RNC receives beep-page message, calling user UE, and records IMSI and MSC/VLR correspondence
Relation.
Step S520：UE is returned and paged reply, wherein because beep-page message uses IMSI, also carries IMSI.
Step S522：BSC or RNC, which is received, to page reply, and according to the IMSI of record and MSC/VLR corresponding relation, looks for
To the MSC/VLR for sending Paging, it will page reply and return to the MSC/VLR.
Step S524：MSC/VLR, RNC or BSC, UE complete remaining be called and establish process.
In above process, RNC or BSC is preserving IMSI and between MSC/VLR numberings by way of relation, to protect
Paging reply for the carrying IMSI that card UE is returned can be routed to the MSC/VLR for sending paging.And during CSFB, this side
Formula does not apply to simultaneously.Reason is that the paging during CSFB is that MME is initiated under LTE network, and BSC or RNC are not participated in
Paging, but directly receive and page reply.So it can not just record IMSI and the corresponding relation with MSC/VLR.So seek
Other MSC/VLR that answers and can be routed in POOL are echoed, other MSC/VLR can abandon the message, so that call interruption.
