METHOD AND DEVICE FOR SELECTING SERVING GATEWAY ENTITY

摘要

Embodiments of the present invention pertain to the communication field and disclose a method and device for selecting a serving gateway entity. The method includes: receiving an access request message of a user equipment UE sent by a base station, where the access request message includes location information of the base station; acquiring, according to the location information of the base station, a signaling plane address list of serving gateway entities SGWs serving the UE; and selecting, according to failure information of paths between the SGWs and neighboring network elements of the SGWs and the acquired signaling plane address list of SGWs serving the UE, an SGW having no failed path to a neighboring network element of the SGW to serve the UE. The device includes: a receiving module, an acquiring module, and a selecting module.

1. A method for selecting a serving gateway entity, wherein the method comprising:
receiving an access request message of a user equipment (UE) sent by a base station, wherein the access request message comprises location information of the base station; acquiring, according to the location information of the base station, a signaling plane address list of serving gateway entities (SGWs) serving the UE; receiving an S1-AP message sent by the base station after the base station detects that a user plane path to a selected SGW fails, wherein the S1-AP message comprises a failure identifier of the user plane path; storing correspondence between information of the base station and a signaling plane address of the selected SGW into failure information of paths between the base station and the neighboring network elements of the SGWs; and selecting, according to the failure information of the paths between the base station and the neighboring network elements of the SGWs and the acquired signaling plane address list of SGWs serving the UE, an SGW having no failed path to a neighboring network element of the SGW to serve the UE.
