1. A method for a user equipment (UE), the method comprising:
after initiating a procedure for releasing all traffic flows for a bearer, receiving, from a mobility management entity (MME), a bearer resource modification reject message with a cause value;
deactivating an evolved packet system (EPS) bearer context locally without peer-to-peer signaling between the UE and the MME, in response to receiving the bearer resource modification reject message; and
transmitting, to the MME, a tracking area update (TAU) request message including an EPS bearer context status information element (IE) to synchronize an EPS bearer context status with the MME,
wherein the cause value indicates that a request related to a bearer resource is rejected due to an unspecified reason.
