Title: METHOD AND APPARATUS FOR REDUCING INTERRUPTION DELAY, AND USER DEVICE
Abstract:
A method and apparatus for reducing interruption delay, and a user device. The method is: in response to an anchor point change operation, a source main network entity of a source network side in a mobile communication network initiates an anchor point change request to a target main network entity of a target network side; on the basis of the received anchor point change request, the target main network entity configures and obtains target network side configuration parameters; on the basis of the received target network side configuration parameters, the source main network entity generates a radio resource control message for the target network side; the target main network entity obtains an anchor point reconstruction indication message generated and transmitted by a multi-connection user device on the basis of the radio resource control message, and enters a target network side configuration effective state for target network side reconstruction, so that the target main network entity becomes a target anchor point of the multi-connection user device, thereby ensuring the seamless transfer of user data.
