Method of changing connection state and apparatus therefor

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.
