METHOD, APPARATUS AND SYSTEM FOR PROCESSING SERVICE REQUEST

摘要

A method, an apparatus, and a system for processing service requests are disclosed herein. The method includes: selecting a second Serving Gateway (SGW) if determining that no user-plane connection exists between an access network device and a first SGW after receiving a service request sent by User Equipment (UE) through the access network device, wherein the first SGW is a preselected SGW corresponding to the UE, and the second SGW has a user-plane connection with the access network device; and setting up a bearer on the second SGW When the UE sends a service request through an access network device which has no user-plane connection with the currently selected SGW, the embodiments of the present invention enable normal implementation of the uplink and downlink services requested by the UE, and avoid frequent relocation of the SGW when an idle UE moves at the border of the service area of the SGW
