Summary:In a communication system in which a plurality of bearers are set up between UE and one or more PGWs, a PGW measures an idle time for each bearer and determines whether or not the measured idle time has reached an idle timer threshold value which is determined in advance for each of the plurality of bearers (Step 1). Then, when it is determined that the idle time for one bearer, for example, bearer 2, has reached the idle timer threshold value (Step 2), a PGW2 requests an MME to release bearer 2 via an SGW2 (Steps 3 and 4), and the MME performs a process of releasing bearer 2 in response to the request (Step 5 and the like).
