Description
Technical field
The present invention relates to wireless communication technology, particularly relating to a kind of method for upgrading TAI-LAI mapping table and device.
Background technology
Due to LTE(Long Term Evolution, Long Term Evolution) standard only supports PS(Packet Switch, packet switching) service, operator needs voice call network of recombinating, and supports the voice call service of LTE terminal.Wherein, CSFB(Circuit Switched Fallback, circuit switched fallback) scheme do not having IMS(IP Multimedia Subsystem, IP Multimedia System) a solution when carrying out support voice call service, in CSFB scheme, LTE network only provides data, services, when mobile terminal is initiated audio call or received audio call, mobile terminal return back to CS(Circuit Switched, circuit switching) territory carries out voice call service.
MME(Mobility Management Entity, mobile management unit) in have a TAI-LAI mapping table, wherein, TAI(Tracking Area Identity, tracing area identifies) be applied to LTE network, LAI(Location Area Identity, location area) be applied to 3G network.There is the network engineering plan under overlapping cases in operator, carrys out this TAI-LAI mapping table of static configuration according to 3G network and LTE network.
When mobile terminal moves to LTE network, the TAI change of this mobile terminal by this TAI-LAI mapping table, can be mapped as LAI change.If the LAI of this mobile terminal changes, the location updating of this mobile network can send to MSC(Mobile Switching Center, mobile switching centre), subsequently, VLR(Visited Location Register, Visited Location Registor) HLR(Home Location Register can be upgraded, attaching position register).
When a LTE mobile terminal needs an end audio call, this calling can be pointed to by the record in HLR access MSC accordingly, corresponding paging request by SGs(Signaling Gateways, SGW) interface transmits between MSC and MME.When MME detects that this paging request is an audio call, then this paging request is sent to this LTE mobile terminal.This LTE mobile terminal is readjusted and is got back to 3G network after receiving this paging request, sends and pages reply to 3G network.Because the TAI-LAI mapping table in MME carrys out manual configuration according to without line overlap engineering project, this TAI-LAI mapping table may not be very accurate or up-to-date, cause often occurring that this calling is pointed to MSC1 by HLR, and this LTE mobile terminal has readjusted back MSC2, then MSC1 can wait for that this is by the response of the paging request of error propagation time-out, thus makes the end failure of this audio call.
MTRR(Mobile Terminating Roaming Retry can be adopted in prior art, roaming retry answered by mobile phone) scheme solves above-mentioned not to be the MSC of the actual rollback of mobile terminal because HLR is the MSC that mobile terminal points to, to cause the situation of call failure.This MTRR scheme is after LTE mobile terminal return back to MSC2, the location updating message of MSC2 is sent to trigger by this LTE mobile terminal, this location updating message is sent to HLR by MSC2, the Waiting for Call of HLR instruct MS C1 cancellation subsequently responds and starts a RCH(ResumeCall Handling, renew Call-Control1) program, in this RCH program, by GMSC(Gateway Mobile Switching Center, GMSC (gateway mobile switching center)) by making a call alternately with the MSC2 at this LTE mobile terminal place.Meanwhile, HLR upgrades the log-on data of HLR and VLR.
Although it is not the MSC of the actual rollback of mobile terminal because HLR is the MSC that mobile terminal points to that MTRR scheme can solve above-mentioned, cause the situation of call failure, but, MTRR scheme relates to multiple core network element, comprise the program of multiple complexity, therefore MTRR scheme can consume more Internet resources, and cause the call set-up time more grown.
