Abstract
A method and apparatus are disclosed for reducing signaling overhead in a wireless communication network. In one embodiment, the method is implemented in a network node. The method includes transmitting a first indication to a UE (User Equipment) to tell the UE to remember a configuration which is currently used after the UE enters RRC_IDLE. In an alternative embodiment, the method is implemented in a UE. The method includes (i) receiving a first indication from the network node to tell the UE to remember a configuration which is currently used after the UE enters RRC_IDLE, and (ii) retaining and not releasing or discarding the configuration upon leaving RRC_CONNECTED.
Claims14
A method implemented in a network node for reducing signaling overhead, comprising:
- transmitting a first indication to a UE (User Equipment) to tell the UE to remember, after the UE enters RRC_IDLE, a first configuration which is currently used while the UE is in RRC_CONNECTED;
- receiving a third indication from the UE to indicate that the UE wants to reuse the first configuration which was used during the last time the UE was in RRC_CONNECTED;
- and
- transmitting a second indication to the UE to tell the UE to reuse the first configuration which was used during the last time the UE was in RRC_CONNECTED.
A network node in a wireless communications system for reducing signaling overhead, the network node comprising:
- a control circuit for realizing functions of the network node;
- a central processing unit coupled to the control circuit for executing a program code to operate the control circuit;
- and
- a memory coupled to the central processing unit for storing the program code;
- wherein the program code comprises:
- transmitting a first indication to a UE (User Equipment) to tell the UE to remember, after the UE enters RRC_IDLE, a first configuration which is currently used while the UE is in RRC_CONNECTED;
- receiving a third indication from the UE to indicate that the UE wants to reuse the first configuration which was used during the last time the UE was in RRC_CONNECTED;
- and
- transmitting a second indication to the UE to tell the UE to reuse the first configuration which was used during the last time the UE was in RRC_CONNECTED.
A method implemented in a UE (User Equipment) for reducing signaling overhead, comprising:
- receiving a first indication from a network node to tell the UE to remember, after the UE enters RRC_IDLE, a first configuration which is currently used while the UE is in RRC_CONNECTED;
- keeping the first configuration upon leaving RRC_CONNECTED;
- transmitting a third indication to the network node to indicate that the UE wants to reuse the first configuration which was used during the last time the UE was in RRC_CONNECTED;
- and
- receiving a second indication from a network node to tell the UE to reuse the first configuration which was used during the last time the UE was in RRC_CONNECTED.
A UE (User Equipment) in a wireless communications system for reducing signaling overhead, the UE comprising:
- a control circuit for realizing functions of the UE;
- a central processing unit coupled to the control circuit for executing a program code to operate the control circuit;
- and
- a memory coupled to the central processing unit for storing the program code;
- wherein the program code comprises:
- receiving a first indication from a network node to tell the UE to remember, after the UE enters RRC_IDLE, a first configuration which is currently used while the UE is in RRC_CONNECTED;
- keeping the first configuration upon leaving RRC_CONNECTED;
- transmitting a third indication to the network node to indicate that the UE wants to reuse the first configuration which was used during the last time the UE was in RRC_CONNECTED;
- and
- receiving a second indication from a network node to tell the UE to reuse the first configuration which was used during the last time the UE was in RRC_CONNECTED.
