Abstract
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.
Claims16
A method performed by an access and mobility management function (AMF) in a wireless communication system, the method comprising:
- receiving, from a terminal, a registration request message;
- determining whether an evolved packet system (EPS) interworking is supported for the terminal based on the registration request message;
- determining whether the EPS interworking with an N26 interface is supported in case that the EPS interworking is supported for the terminal;
- determining information on whether to support an access traffic steering, switching and splitting (ATSSS) in case that the EPS interworking with an N26 interface is supported;
- and
- transmitting, to the terminal, a registration response message including the information.
A method performed by a terminal in a wireless communication system, the method comprising:
- transmitting, to an access and mobility management function (AMF), a registration request message;
- receiving, from the AMF, a registration response message in response to the registration request message;
- determining whether the AMF supports an access traffic steering, switching and splitting (ATSSS) based on information including the registration response message;
- determining whether an evolved packet system (EPS) interworking is required, and the EPS interworking with an N26 interface is supported, in case that the AMF supports the ATSSS;
- and
- performing the ATSSS in case that the EPS interworking is not required, or the EPS interworking with the N26 interface is supported.
An access and mobility management function (AMF) in a wireless communication system, the AMF comprising:
- a transceiver capable of transmitting and receiving at least one signal;
- and
- a controller coupled to the transceiver, wherein the controller is configured to:
- receive, from a terminal, a registration request message,
- determine whether an evolved packet system (EPS) interworking is supported for the terminal based on the registration request message,
- determine whether the EPS interworking with an N26 interface is supported in case that the EPS interworking is supported for the terminal,
- determine information on whether to support an access traffic steering, switching and splitting (ATSSS) in case that the EPS interworking with an N26 interface is supported, and
- transmit, to the terminal, a registration response message including the information.
