Abstract
Systems and methods are disclosed herein that relate to configuration of a periodic updating timer for, e.g., a Radio Access Network (RAN)—controlled inactive state. In some embodiments, a method of operation of a RAN node in a cellular communications network comprises configuring a User Equipment (UE) with a timer value T for a periodic updating timer. In this manner, the RAN node is able to configure the UE with a time value T, e.g., for use by the UE for providing periodic update messages while the UE is operating in an inactive state such as, e.g., a RAN-controlled inactive state.
Claims11
A method of operation of a Radio Access Network, RAN, base station in a cellular communications network, comprising:
- sending, to a User Equipment, UE, a release message for moving the UE to a RAN controlled inactive state, wherein the release message comprises a configuration of a timer value T for a periodic updating timer.
A Radio Access Network, RAN, base station for a cellular communications network, the RAN node comprising:
- one or more transmitters;
- and
- processing circuitry configured to:
- send, to a User Equipment, UE, a release message for moving the UE to a RAN controlled inactive state, wherein the release message comprises a configuration of a timer value T for a periodic updating timer.
A method of operation of a User Equipment, UE, in a cellular communications network, comprising:
- receiving, from a Radio Access Network, RAN, base station, a release message for moving the UE to a RAN controlled inactive state, during which state a UE RAN context is stored in the UE, wherein the release message comprises a configuration of a timer value T for a periodic updating timer;
- starting the periodic updating timer at entry of the RAN controlled inactive state;
- and
- upon expiry of the periodic updating timer, sending a periodic update message.
A User Equipment, UE, for a cellular communications network, the UE comprising:
- one or more transmitters;
- one or more receivers;
- and
- processing circuitry configured to:
- receive, from a Radio Access Network, RAN, base station, a release message for moving the UE to a RAN controlled inactive state, during which state a UE RAN context is stored in the UE, wherein the release message comprises a configuration of a timer value T for a periodic updating timer;
- start the periodic updating timer at entry of the RAN controlled inactive state;
- and
- upon expiry of the periodic updating timer, send a periodic update message.
