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 UE. The method includes 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. The method also includes keeping the first configuration upon leaving RRC_CONNECTED. The method further includes releasing the first configuration when the UE connects to a RAT different from where the first indication was received.
