Abstract
A network selection method is provided that includes acquiring, by a first base station, core network type information of a core network node from UE, a second base station or a first core network node; and selecting, by the first station, a core network node for the UE according to the acquired core network type information and information about a second core network node provided by the UE.
Claims8
A method performed by a base station in a communication system, the method comprising:
- receiving, from at least one network entity, a first message which is a response message associated with an interface setup procedure, the first message including first information on a service type supported by the at least one network entity;
- receiving, from a terminal, a second message including a radio resource control (RRC) setup complete message;
- identifying a network entity of the at least one network entity for the terminal;
- based on the first information and second information on a service type, the second information being included in the second message;
- and
- transmitting, to the network entity, an initial message of the terminal,
- wherein a default network entity is identified instead of the network entity, in case that the second information is not received from the terminal.

A base station in a wireless communication system, the base station comprising:
- a transceiver;
- and
- a controller configured to:
- receive, from at least one network entity, a first message which is a response message associated with an interface setup procedure, the first message including first information on a service type supported by the at least one network entity,
- receive, from a terminal, a second message including a radio resource control (RRC) setup complete message,
- identify a network entity of the at least one network entity for the terminal, based on the first information and second information on a service type, the second information being included in the second message, and
- transmit, to the network entity, an initial message of the terminal,
- wherein a default network entity is identified instead of the network entity, in case that the second information is not received from the terminal.

A method performed by a network entity in a communication system, the method comprising:
- receiving, from a base station, a first message associated with an interface setup procedure between the base station and the network entity;
- transmitting, to the base station, a second message associated with the interface setup procedure as a response to the first message, the second message including first information on a service type supported by the network entity;
- and
- receiving, from the base station, a third message associated with a terminal, the third message including second information on a service type,
- wherein an initial message is received, from the base station, in case that the network entity of at least one network entity is selected by the base station based on the first information and the second information on the service type,
- wherein a radio resource control (RRC) setup complete message including the second information is transmitted from the terminal to the base station, and
- wherein a default network entity is selected by the base station instead of the network entity, in case that the second information is not transmitted from the terminal to the base station.
