Title:
COMMUNICATION CONTROL METHOD AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/061920
Kind Code:
A1
Abstract:
In this communication system where a plurality of bearers are set between a UE and one or more PGWs, the PGWs measure an idle time for each of the bearers, and determine, for each of the bearers, whether or not the measured idle time has reached an idle timer threshold set in advance for the plurality of bearers (step 1). When determining, for one of the bearers, for example, bearer 2, that the idle timer has reached the idle timer threshold (step 2), a PGW 2 requests, via a SGW 2, an MME to release the bearer 2 (steps 3, 4), and the MME executes a process of releasing the bearer 2 in accordance with the request (step 5, etc.).
