Method, system, and device for switching

摘要: Embodiments of the present invention relate to technical field wireless communications, and specifically a method, system device for switching, use in solving problem prior art risk communication interruption when user equipment (UE) is switching due greatly increased frequency number times by UE an E-UTRAN network architecture. The method embodiments comprises: receives DRB reconfiguration message from macro base station; keeps PDCP layer corresponding all DRBs control side at station, switches other layers some or except onto least one station. Because reduce UE, case architecture, reduced switching.
