Abstract

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 disclosure, 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 disclosure, 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 disclosure, 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.

Claims

1. A network connection method of a terminal in a communication system, the method comprising:

receiving an information including a registration order from a configuration server;

storing the received information; and

transmitting a connection request to a network according to a connection mode determined based on the stored information.

2. The method of claim 1, wherein the receiving of the information including the registration order comprises receiving the information indicating whether to connect a Packet Switching (PS) domain with priority, a Circuit Switched (CS) domain with priority, or both the PS and CS domains simultaneously.

3. The method of claim 1, further comprising performing, at the terminal, initial attach to the configuration server for connection to the network.

4. The method of claim 1, further comprising receiving a response message from the network, the response message including a list of functions supported by a domain to which the terminal has connected.

5. The method of claim 1, wherein the configuration server comprises an Open Mobile Alliance Device Management (OMA-DM) server.

6. A terminal for connecting to a wireless communication system, the terminal comprising:

a transceiver configured to receive an information including a registration order from a configuration server; and

a controller configured to receive the received information and control the transceiver to transmit a connection request to a network according to a connection mode determined based on the stored information.

7. The terminal of claim 6, wherein the transceiver is configured to receive the information indicating whether to connect a Packet Switching (PS) domain with priority, a Circuit Switched (CS) domain with priority, or both the PS and CS domains simultaneously.

8. The terminal of claim 6, wherein the transceiver is configured to perform, at the terminal, initial attach to the configuration server for connection to the network.

9. The terminal of claim 6, wherein the transceiver is configured to receive a response message from the network, the response message including a list of functions supported by a domain to which the UE has connected.

10. The terminal of claim 6, wherein the configuration server comprises an Open Mobile Alliance Device Management (OMA-DM) server.

11. A communication method of a terminal in a communication system, the method comprising:

transmitting/receiving signals in a first communication domain;

determining communication in a second communication domain different from the first communication domain;

transmitting a message including location information of the terminal and information on the first communication domain through the network of the first communication domain; and

receiving a list including an order of communication domains to which the terminal can connect based on the message from the network.

12. A terminal of a communication system, the terminal comprising:

a transceiver configured to transmit and receive signals in a first communication domain; and

a controller which configured to determine communication in a second communication domain different from the first communication domain;

wherein the transceiver is configured to transmit a message including location information of the terminal and information on the first communication domain through the network of the first communication domain and receive a list including an order of communication domains to which the terminal can connect based on the message from the network.
