Patent ID: 8718651

Claim:
A method for informing a serving cell handover, comprising: setting up, by a radio network controller (RNC) a radio link with a candidate cell, and setting configuration for the candidate cell during the process of setting up the radio link; sending, by the RNC, configuration information of the candidate cell to a user equipment (UE); and informing, by the RNC, after acquiring an optimum cell, through an Iub interface signaling message, a target base station of sending a serving cell handover instruction to the UE, wherein the Iub interface signaling message carries the number of repeated times of a Shared Control Channel for High-Speed Downlink Shared Channel (HS-SCCH) order, and wherein the serving cell handover instruction is used to instruct the UE to hand over to the optimum cell according to the configuration information and wherein the Iub interface signaling message comprises mode indication information to indicate one of a synchronous or asynchronous mode.
