Abstract
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to the disclosure, a 3GPP 5GS (5G System) may provide a multiple-access-based network selection function for selecting a network for multiple 3GPP accesses in order to provide multiple 3GPP accesses to a wireless terminal.
Claims20
A method performed by a terminal in a wireless communication system, the method comprising:
- transmitting, to a first access and mobility management function (AMF) entity via a first base station, a first registration request message for a multiple access;
- receiving, from the first AMF entity via the first base station, a first registration response message including at least one of a multi-access network selection list or information on a policy for the terminal in response to transmitting the first registration request message, in case that the at least one of the multi-access network selection list or the information on the policy for the terminal is updated;
- updating, based on the first registration response message, the at least one of the multi-access network selection list or the information on the policy for the terminal;
- and
- selecting a second base station for the multiple access based on the updated at least one of the multi-access network selection list or the information on the policy for the terminal.

A method performed by a first access and mobility management function (AMF) entity in a wireless communication system, the method comprising:
- receiving, from a terminal via a first base station, a first registration request message for a multiple access, wherein the first registration request message for the multiple access includes at least one of information of a capability for the terminal, a terminal indication, a network indication, a requested network slice identities, a cell identity for the terminal, or an access type for the terminal;
- determining whether to update at least one of a multi-access network selection list or information on a policy for the terminal;
- and
- transmitting, to the terminal via the first base station, a first registration response message including at least one of the at least one of the multi-access network selection list or the information on the policy for the terminal in response to receiving the first registration request message in case that the at least one of a multi-access network selection list, or the information on the policy for the terminal is updated.

A terminal in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- at least one processor configured to:
- transmit via the transceiver, to a first access and mobility management function (AMF) entity via a first base station, a first registration request message for a multiple access,
- receive, from the first AMF entity via the first base station, a first registration response message including at least one of a multi-access network selection list or information on a policy for the terminal in response to transmitting the first registration request message, in case that the at least one of the multi-access network selection list or the information on the policy for the terminal is updated,
- update, based on the first registration response message, the at least one of the multi-access network selection list or the information on the policy for the, and
- select a second base station for the multiple access based on the updated at least one of the multi-access network selection list or the information on the policy for the terminal.
