Abstract: A method and apparatus for performing a L3 handover between CNs in a packet-switched network are provided. When a UE moves from an old RAN to a new RAN, the UE sends a measurement report message including cell information to the old RAN. The old or new RAN determines whether to perform a L3 handover. If the L3 handover is required, a tunnel is established between the new RAN and a new CN. The UE performs a handover from the old RAN to the new RAN, without establishing a tunnel between the new RAN and an old CN. Upon detection of the movement of the UE, the new RAN sends a L2 handover complete message to the old RAN. After moving to the new RAN, the UE acquires a new IP address, performs the L3 handover, and communicates with the new CN through the new RAN.

Abstract translation: 提供了一种用于在分组交换网络中的CN之间执行L3切换的方法和装置。 当UE从旧的RAN移动到新的RAN时，UE向旧的RAN发送包括小区信息的测量报告消息。 旧的或新的RAN确定是否执行L3切换。 如果需要L3切换，则在新的RAN和新的CN之间建立隧道。 UE不会在新的RAN和旧的CN之间建立隧道，从旧的RAN进行到新的RAN的切换。 在检测到UE的移动时，新的RAN向旧的RAN发送L2切换完成消息。 移动到新的RAN后，UE获取新的IP地址，执行L3切换，并通过新的RAN与新的CN进行通信。
