Abstract:
A reordering method in a communication system where a base station sends to a mobile station, packets to which numbers indicating a sequence are attached, the mobile station rearranges the packets in order of the sequence numbers, and a hard handover is performed. The method includes deciding whether a handover source base station forwards packets which have not yet been sent to the mobile station, out of packets received from a host station, to a handover target base station; controlling forwarding of the packets at the handover based on the decision, and sending forwarding execution information from the handover source base station to the mobile station to notify whether the forwarding of the packets has been executed; and at the mobile station, receiving the forwarding execution information, and executing reordering of the packets received from the handover target base station based on the forwarding execution information at the handover.
