Abstract

The invention provides a method for quickly restoring user equipment services after restarting of a service gateway, and a device. The method comprises the following steps: a mobile management entityMME receives an echo request message sent by the service gateway SGW; the MME sends a session reestablishment request message to the SGW so as to enable the SGW to reestablish a bearer for the user equipment UE according to the session reestablishment request message, wherein the echo request message comprises an indication message cell for session reestablishment, and the session reestablishmentrequest message comprises bearer information of the UE. In the method provided by the embodiment of the invention, when the SGW is restarted, interruption time of the UE services can be reduced to beshortest, namely, a reestablishment flow can be executed as long as restarting of the SGW is completed; through the reestablishment flow triggered at inside of a network side, the UE cannot sense network exceptions, time for restoring the user equipment services is shortened, and network load is reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for quickly restoring services of user equipment after a service gateway is restarted. Background technique [0002] In LTE (Long Term Evolution, long-term evolution system), between the network side MME (Mobility Management Entity, mobile management entity) and SGW (Serving GateWay, serving gateway) through Create SessionRequest / Create Session Response (create session request / create session response) as A UE (User Equipment, user equipment) establishes an EPS (Evolved Packet System, evolved packet system) service session context. Create a service-specific bearer through Bearer Resource Command (bearer resource command), Create Bearer Request / Create BearerResponse (create bearer request / create bearer response). [0003] When the SGW restarts, according to the 3GPP protocol, the MME should release the service resources allocated to all UEs on the S...
