Abstract
Disclosed are a control plane signaling method and apparatus for reducing signaling according to a state change of a UE, and a method of efficiently changing a UE connection UE in a wireless network without movement or a state transition change of a UE in a core network. A method of changing a connection state by a UE includes: transmitting UE capability information indicating that the UE supports a light connection to an eNB; receiving a Radio Resource Control (RRC) message including indication information indicating a state change to a light connection state from the eNB; and changing a connection state of the UE from an RRC-connected state to the light connection state based on the indication information.
Claims19
A method of changing a connection state by a user equipment (UE), the method comprising:
- transmitting UE capability information indicating that the UE supports a light connection to an E Node B (eNB);
- receiving a Radio Resource Control (RRC) message including indication information that indicates a state change to a light connection state from the eNB;
- and
- changing a connection state of the UE from an RRC-connected state to the light connection state based on the indication information.
A method of changing a connection state of a user equipment (UE) by an E Node B (eNB), the method comprising:
- receiving UE capability information indicating that the UE supports a light connection state from the UE;
- transmitting a Radio Resource Control (RRC) message including indication information that indicates a state change to a light connection state to the UE;
- and
- changing a connection state with the UE from an RRC-connected state to the light connection state,
- wherein the light connection state corresponds to a state in which a connection state between the eNB and a core network for the UE is maintained but all Signaling Radio Bearers (SRBs) and Data Radio Bearers (DRBs) are suspended.
A user equipment (UE) changing a connection state, the UE comprising:
- a transmitter configured to transmit UE capability information indicating support of a light connection to an eNB;
- a receiver configured to receive a Radio Resource Control (RRC) including indication information indicating a state change to a light connection state from the eNB;
- and
- a controller configured to change a connection state of the UE from an RRC-connected state to the light connection state.
