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 by a terminal in a communication system, the method comprising:

receiving, from a server, a first message including information on a registration order among at least one domain corresponding to a network, the at least one domain comprising a packet switched (PS) domain and a circuit switched (CS) domain, the information on the registration order being identified based on a supported function corresponding to the network, the information on the registration order including information for a priority among the PS domain, the CS domain, and combined both the PS domain and the CS domain;

identifying a domain for a connection based on the information on the registration order;

transmitting, to an entity of the network, a second message including information on a service required for the terminal and a request for the connection based on the identified domain for the connection;

receiving, from the entity of the network, a response message based on the information on the service, the response message including comprising information on a function supported by a connected domain of the terminal; and

transmitting, to the entity of the network, a fourth message including an additional request for a connection based on the information on the function supported by the connected domain of the terminal.

2. The method of claim 1, further comprising:

transmitting, to the server, a third message related to an initial attach for connection to the network.

3. The method of claim 1, wherein the server comprises an open mobile alliance device management (OMA-DM) server.

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

a transceiver configured to receive and transmit at least one signal; and

a controller electrically coupled to the transceiver and configured to;

control the transceiver to receive, from a server, a first message including information on a registration order among at least one domain corresponding to a network, the at least one domain comprising a packet switched (PS) domain and a circuit switched (CS) domain, the information on the registration order being identified based on a supported function corresponding to the network, the information on the registration order including information for a priority among the PS domain, the CS domain, and combined both the PS domain and the CS domain;

identify a domain for a connection based on the information on the registration order;

control the transceiver to transmit, to an entity of the network, a second message including information on a service required for the terminal and a request for the connection based on the identified domain for the connection;

control the transceiver to receive, from the entity of the network, a response message based on the information on the service, the response message including information on a function supported by a connected domain of the terminal; and

control the transceiver to transmit, to the entity of the network, a fourth message including an additional request for a connection based on the information on the function supported by the connected domain of the terminal.

5. The terminal of claim 4, wherein the controller is further configured to control the transceiver to transmit, to the server, a third message related to an initial attach for connection to the network.

6. The terminal of claim 4, wherein the server comprises an open mobile alliance device management (OMA-DM) server.

7. A method by an entity of a network in a communication system, the method comprising:

receiving, from a terminal, a first message including information on a service required for the terminal and a request for a connection corresponding to a domain identified based on information on a registration order among at least one domain corresponding to the network, the information on the registration order including information for a priority among a packet switched (PS) domain, a circuit switched (CS) domain, and combined both the PS domain and the CS domain, the at least one domain comprising the PS domain and the CS domain, the information on the registration order being identified based on a supported function corresponding to the network;

identifying information on a function supported by a connected domain of the terminal based on the first message;

transmitting, to the terminal, a response message based on the information on the service, the response message including the information on a function supported by a connected domain of the terminal; and

receiving, from the terminal, a second message including an additional request for a connection based on the information on the function supported by the connected domain of the terminal.

8. The method of claim 7, wherein an initial attach for connection to the network is transmitted from the terminal to a server related to the information on the registration order.

9. The method of claim 8, the server comprises an open mobile alliance device management (OMA-DM) server.

10. An apparatus of an entity of a network in a communication system, the apparatus comprising:

a transceiver configured to receive and transmit at least one signal; and

a controller electrically coupled to the transceiver and configured to;

control the transceiver to receive, from a terminal, a first message including information on a service required for the terminal and a request for a connection corresponding to a domain identified based on information on a registration order among at least one domain corresponding to the network, the information on the registration order including information for a priority among a packet switched (PS) domain, a circuit switched (CS) domain, and combined both the PS domain and the CS domain, the at least one domain comprising the PS domain and the CS domain, the information on the registration order being identified based on a supported function corresponding to the network;

identify information on a function supported by a connected domain of the terminal based on the first message;

transmit, to the terminal, a response message based on the information on the service, the response message including the information on a function supported by a connected domain of the terminal; and

receive, from the terminal, a second message including an additional request for a connection based on the information on the function supported by the connected domain of the terminal.

11. The apparatus of claim 10, wherein an initial attach for connection to the network is transmitted from the terminal to a server related to the information on the registration order.

12. The apparatus of claim 11, the server comprises an open mobile alliance device management (OMA-DM) server.
