First Claim
1. A method for communication of a terminal in a communication system, the method comprising:
- identifying a bearer associated with the terminal;
determining whether the bearer associated with the terminal is needed to be deactivated in order to request an emergency bearer;
deactivating the bearer locally, in case that the bearer is needed to be deactivated;
transmitting, to a mobility management entity, a first message comprising information on a status of the bearer, in case that the bearer is deactivated locally; and

Abstract
In a user equipment of a wireless communication system, a method for signal transmission and reception may include: sending a request for a Circuit Switched voice network (CS) service to a Gateway Mobile Switching Center (GMSC) to send and receive data to and from a second user equipment; and receiving a call reject response corresponding to the service request from the GMSC, wherein the call reject response is sent by an entity in a core network of the second user equipment. According to an embodiment, it is possible to provide a suitable service to a sender terminal making a CS service request to a receiver terminal having subscribed only to a PS service without increasing network load.
