Abstract
This disclosure provides a User Equipment (UE), including: a transmitter configured to transmit at least one Protocol Data Unit (PDU) session identifier (ID), each of which indicates a PDU session that the UE needs to use in a Non Access Stratum (NAS) Service Request message to a Mobility Management Function (MMF) via an access network (AN) node when the UE has user data to send.
Claims21
A method performed in a User Equipment (UE), the method comprising:
- sending, to a second core network node, a first request so that a User Plane resource is released,
- receiving, from a radio station, a modification message;
- and
- sending, toward the second core network node, a session ID over the radio station, wherein
- the first request includes the session ID and indication about release, and
- the session ID corresponds to a first core network node different from the second core network node.

A method performed in a second core network node, the method comprising:
- receiving, from a User Equipment (UE), a first request so that a User Plane resource is released,
- receiving, from the UE, a session ID over a radio station;
- and
- sending, to a first core network node, the first request;
- wherein
- the first request includes session ID and indication about release, and
- the session ID corresponds to the first core network node different from the second core network node.
4 more elements
A User Equipment (UE) comprising:
- a memory having stored therein program instructions;
- and
- at least one processor that when executing the program instructions is configured to:
- send, to a second core network node, a first request so that a User Plane resource is released,
- receive, from a radio station, a modification message;
- and
- send, toward the second core network node, a session ID over the radio station, wherein
- the first request includes the session ID and indication about release, and
- the session ID corresponds to a first core network node different from the second core network node.
