Abstract
The method proposes to establish at least one session between the User Equipment and the Session Management Function node, and initiate session deactivation for a session indicated by the User Plane Function node, upon detection inactivity of User Plane connection for the session for a period by the User Plane Function node.
Claims4
A User Equipment (UE) comprising:
- a memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- send a request message for a Protocol Data Unit (PDU) session establishment to a Session Management Function (SMF) node, and
- receive, from the SMF node, a response message for the PDU session establishment, after the SMF node communicates with a User Plane Function (UPF) node to provide an inactivity timer for deactivation of the PDU session to the UPF node.
