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.

1-13. (canceled)
A Session Management Function (SMF) node comprising:
- a memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- establish a Protocol Data Unit (PDU) session with a User Equipment (UE),
- transmit a message including an inactivity timer for the PDU session, to a User Plane Function (UPF) node, and
- receive, from the UPF node, information for initiating session deactivation for the PDU session.
A User Plane Function (UPF) node comprising:
- a memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- receive a message including an inactivity timer for a Protocol Data Unit (PDU) session between a User Equipment (UE) and a Session Management Function (SMF) node, from the SMF node;
- detect inactivity of user data transfer for the PDU session, for a period;
- and
- transmit, to the SMF node, information for initiating, by the SMF node, session deactivation for the PDU session.
A mobile communication system comprising:
- a Session Management Function (SMF) node and a User Plane Function (UPF) node, and wherein
- the SMF node is configured to:
- establish a Protocol Data Unit (PDU) session with a User Equipment (UE),
- transmit a message including an inactivity timer for the PDU session, to the UPF node, and
- receive, from the UPF node, information for initiating session deactivation for the PDU session, and
- the UPF node is configured to:
- receive the message including the inactivity timer for the PDU session, from the SMF node;
- detect inactivity of user data transfer for the PDU session, for a period;
- and
- transmit, to the SMF node, information for initiating, by the SMF node, session deactivation for the PDU session.
A session management method comprising:
- establishing a Protocol Data Unit (PDU) session with a User Equipment (UE);
- transmitting a message including an inactivity timer for the PDU session, to a User Plane Function (UPF) node;
- and
- receiving, from the UPF node, information for initiating session deactivation for the PDU session.
A User Equipment (UE) inactivity detecting method, comprising:
- receiving a message including an inactivity timer for a Protocol Data Unit (PDU) session between a User Equipment (UE) and a Session Management Function (SMF) node, from the SMF node;
- detecting inactivity of user data transfer for the PDU session, for a period;
- and
- transmitting, to the SMF node, information for initiating, by the SMF node, session deactivation of the PDU session.
A non-transitory computer readable recording medium recording a program, the program, when executed by a processor of a computing device, causing the processor to execute a session management method comprising:
- establishing a Protocol Data Unit (PDU) session with a User Equipment (UE);
- transmitting a message including an inactivity timer for the PDU session, to a User Plane Function (UPF) node;
- receiving, from the UPF node, information for initiating session deactivation for the PDU session.
A non-transitory computer readable recording medium recording a program, the program, when executed by a processor of a computing device, causing the processor to execute a User Equipment (UE) inactivity detecting method, comprising:
- receiving a message including an inactivity timer for a Protocol Data Unit (PDU) session between a User Equipment (UE) and a Session Management Function (SMF) node, from the SMF node;
- detecting inactivity of user data transfer for the PDU session, for a period;
- and
- transmitting, to the SMF node, information for initiating, by the SMF node, session deactivation of the PDU session.
