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 a terminal in a wireless communication system, the method comprising:
- establishing a multiple-access protocol data unit (MA PDU) session in a 3rd generation partnership project (3GPP) access and a non-3rd generation partnership project (N3GPP) access in a 5th-generation system (5GS);
- determining whether the MA PDU session is moved to an evolved packet system (EPS) without an N26 interface between the 5GS and the EPS after the establishing the MA PDU session;
- and
- releasing a context related to an access traffic steering, switching and splitting (ATSSS), wherein the context related to the ATSSS is associated with ATSSS rules and measurement assistance information for the MA PDU session,
- wherein a release of the MA PDU session is triggered over the N3GPP access by a network entity in the 5GS.
A method performed by a network entity in a 5th-generation system (5GS) in a wireless communication system, the method comprising:
- triggering a release of a multiple-access protocol data unit (MA PDU) session over a non-3rd generation partnership project (N3GPP) access;
- and
- releasing a context related to an access traffic steering, switching and splitting (ATSSS), wherein the context related to the ATSSS is associated with ATSSS rules and measurement assistance information for the MA PDU session,
- wherein the MA PDU session is established in both a 3rd generation partnership project (3GPP) access and the N3GPP access in the 5GS, and
- wherein the MA PDU session is moved to an evolved packet system (EPS) without an N26 interface between the 5GS and the EPS.
A terminal, 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:
- establish a multiple-access protocol data unit (MA PDU) session in a 3rd generation partnership project (3GPP) access and a non-3rd generation partnership project (N3GPP) access in a 5th-generation system (5GS),
- determine whether the MA PDU session associated with the terminal is moved to an evolved packet system (EPS) without an N26 interface between the 5GS and the EPS after establishing the MA PDU session, and
- release a context related to an access traffic steering, switching and splitting (ATSSS), wherein the context related to the ATSSS is associated with ATSSS rules and measurement assistance information for the MA PDU session,
- wherein a release of the MA PDU session is triggered over the N3GPP access by a network entity in the 5GS.
A network entity in a 5th-generation system (5GS), the network entity 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:
- trigger a release of a multiple-access protocol data unit (MA PDU) session over a non-3rd generation partnership project (N3GPP) access, and
- release a context related to an access traffic steering, switching and splitting (ATSSS), wherein the context related to the ATSSS is associated with ATSSS rules and measurement assistance information for the MA PDU session,
- wherein the MA PDU session is established in both a 3rd generation partnership project (3GPP) access and the N3GPP access in the 5GS, and
- wherein the MA PDU session is moved to an evolved packet system (EPS) without an N26 interface between the 5GS and the EPS.
