Routing configuration method and device

Abstract

Embodiments of the invention provide a routing configuration method and a device. The method comprises steps of: obtaining identification information carried inside an access request sent by a user terminal UE (User Experience), wherein the identification information is used for identifying the UE uniquely; sending an initialization request carrying identification information to an evolved packetcore (EPC) network, so that the EPC allocates a corresponding target serving gateway (SGW) for the UE based on the identification information; receiving an initialization response returned by the EPC,wherein the initialization response carries target address information of the target SGW; matching the target address information with the address information in the local routing table; and updatingthe local routing table according to the target address information, if the matching fails. Therefore, the address information of the SGW can be obtained automatically, and the routing table is updated according to the obtained address information of the SGW, thereby avoiding the mishandling problem caused by the manual configuration, ensuring the success rate of the UE access, and improving theefficiency of the route configuration and the user experience.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a routing configuration method and device. Background technique [0002] In the process of UE (User Equipment, user terminal) accessing EPC (Evolved Packet Core, evolved core network), the base station, as an intermediate device, needs to provide MME (Mobility Management Entity, mobile The address information of the management entity) and the address information of the SGW (Serving Gateway, Serving Gateway), the connection channel between the UE, the MME and the SGW has been established. [0003] In the prior art, the method for the base station to obtain the address information of the SGW is usually manual configuration, that is, the operator configures the address information of the SGW at the base station at the initial stage of station opening. However, misoperations that may occur due to manual configuration will lead to wrong or unconfigured SGW rou...

Problems solved by technology

[0004] Embodiments of the present invention provide a routing configuration method and device to solve the problem in the prior art that due to manual configuration, the configuration of SGW routing information at the base station is wrong or unconfigured, and the UE cannot successfully access the EPC.
