Abstract:
The present specification provides a method for connecting an IP multimedia subsystem (IMS)-based service in a terminal. The method for connecting the IMS-based service, includes the steps of: setting a cause value denoting signaling or due to the IMS in an establishment cause field, when a session initiation protocol (SIP)-based message is required to be transmitted on a user plane for connecting the IMS-based service; transmitting a service request message of a non-access stratum (NAS) layer including service type (field) denoting signaling or due to a base station; and transmitting a radio resource control (RRC) connection request message including the set establishment cause field to the base station.
