Abstract
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). Then, when it is determined that the idle time for one bearer, for example, bearer, has reached the idle timer threshold value (Step), a PGWrequests an MME to release bearervia an SGW(Stepsand), and the MME performs a process of releasing bearerin response to the request (Stepand the like).
