According to an embodiment, a network access method of a user equipment (UE) in a communication system comprises the steps of: receiving information including an access order from a configuration server; storing the received information; and transmitting an access request to the network according to an access method determined on the basis of the stored information. According to another embodiment, a UE for accessing a wireless communication system comprises: a transceiving unit which receives information including an access order from a configuration server; and a control unit for storing the received information and controlling the transceiving unit to transmit an access request to the network according to an access method determined on the basis of the stored information. According to an embodiment of the present invention, when a UE for supporting a PS network and a CS network accesses a network, the UE receives a configuration of each domain registration method in advance, and thus can more easily access each network. In addition, according to another embodiment of the present invention, message transmission can be more easily achieved between a system in which a long SMS message can be transmitted and a system in which a SMS message of conventional-length is transmitted. Furthermore, according to another embodiment of the present invention, when a UE, which has performed a CS fallback, returns to a 4G network due to the end of a CS service, the UE can be prevented from returning to another provider network since the UE has existing return information. |
