Description
Technical field
The present invention relates to wireless communication technology fields, and in particular to a kind of gateway restarts the fast of rear user apparatus service
Quick-recovery method.
Background technology
In LTE (Long Term Evolution, long evolving system), network side MME (Mobility Management
Entity, mobile management entity) between SGW (Serving GateWay, gateway) pass through Create Session
Request/Create Session Response (creating session request/establishment conversational response) are UE (User
Equipment, user equipment) establish EPS (Evolved Packet System, evolved packet system) service conversation context.
Pass through Bearer Resource Command (bearing resource order), Create Bearer Request/Create Bearer
Response (creating carrying request/establishment carrying response) establishes business dedicated bearing.
When SGW is restarted, according to 3GPP agreements, MME should discharge the service resources of distribution all UE on the SGW, MME
It triggers S1 and discharges flow, UE enters ECM-IDLE (idle mode) state, service disconnection.After S-GW is restarted, when UE sends Service
When Request (service request) carries out business again, according to 3GPP agreements, by sending Service Reject, (refusal takes MME
Business) message (it is " Implicitly detached (implicit detach) " to carry cause value), by UE implicit detach.UE is received
Judge cause value after Service Reject message, will initiate to adhere to again, after UE complete EPS session establishments after could continue into
Industry is engaged in.
Fig. 1 is that user apparatus service interrupts in the prior art and the signalling diagram of restoration methods, detailed process are：
(1) MME is sent by eNB (evolved Node B, evolved base station) to UE
UeContextReleaseCommand message discharges S1 connections.
(2) UE sends UeContextReleaseResponse message by eNB to MME, indicates that release S1 connections are completed.
(3) UE enters ECM-IDLE states, and UE initiates ServiceRequest message recovery business.
(4) carrying informations of the MME without the UE sends Service Reject message to UE, carries cause value and is
“Implicitly detached”。
(5) UE adheres to again after receiving Service Reject message, completes EPS session establishments.
After SGW is restarted in the prior art, UE enters ECM-IDLE states, leads to service disconnection.When to the business recovery of UE
Between it is longer, cannot be satisfied the business demand of certain specific industry data highly-reliable transmissions, such as rail traffic CPTC service disconnections
No more than 2 seconds.And follow-up UE continues business, needs a plurality of signaling process, network load is caused to increase.
