Abstract
A method of inter-system change of Multi-Access (MA) Protocol Data Unit (PDU) session, performed by a user equipment (UE), includes establishing an MA PDU session with user-plane resources over a 3GPP access network in N1 mode, establishing a first Public Data Network (PDN) connection over an untrusted non-3GPP access network as a user-plane resource of the MA PDU session, transferring the MA PDU session to an Evolved Packet System (EPS) as a second PDN connection, and releasing the MA PDU session locally in response to transferring the MA PDU session to the EPS.
Claims22
A method of inter-system change of a Multi-Access (MA) Protocol Data Unit (PDU) session, performed by user equipment (UE), comprising:
- establishing an MA PDU session with user-plane resources over a 3GPP access network in N1 mode;
- establishing a first Public Data Network (PDN) connection over an untrusted non-3GPP access network as a user-plane resource of the MA PDU session;
- transferring the MA PDU session to an Evolved Packet System (EPS) as a second PDN connection;
- and
- releasing the MA PDU session locally in response to transferring the MA PDU session to the EPS.
A method of inter-system change of Multi-Access (MA) Protocol Data Unit (PDU) session, performed by a network entity, comprising:
- receiving a request for establishing an MA PDU session for user-plane resources over a 3GPP access network in N1 mode;
- receiving a request for establishing a first Public Data Network (PDN) connection over an untrusted non-3GPP access network as a user-plane resource of the MA PDU session;
- transferring the MA PDU session to an Evolved Packet System (EPS) as a second PDN connection;
- and
- releasing the MA PDU session in response to transferring the MA PDU session to the EPS.
A user equipment (UE) comprising:
- a memory for storing program instruction and data;
- and
- a processor coupled to the memory, configured to:
- establish an MA PDU session with user-plane resources over a 3GPP access network in N1 mode;
- establish a first Public Data Network (PDN) connection over an untrusted non-3GPP access network as a user-plane resource of the MA PDU session;
- transfer the MA PDU session to an Evolved Packet System (EPS) as a second PDN connection;
- and
- release the MA PDU session locally in response to transferring the MA PDU session to the EPS.
