METHOD AND APPARATUS FOR REDUCING SIGNALING OVERHEAD IN A WIRELESS COMMUNICATION NETWORK

摘要

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.

1. A method implemented in a UE (User Equipment), 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; and releasing the first configuration when the UE connects to a Radio Access Technology (RAT) different from where the first indication was received.
