HANDOVER METHOD IN RADIO COMMUNICATION SYSTEM, RADIO BASE STATION, AND RADIO TERMINAL

摘要

In the method for handover of the present invention, a first wireless base station (1-1) sends a second wireless base station (1-2) first forward order information provided to the first data destined for a wireless terminal (3); and the second wireless base station (1-2) sends the wireless terminal (3) the first data forwarded from the first wireless base station (1-1) and provides second forward order information obtained through adding an offset value to the first forward order information to second data which the second wireless station (1-2) has received from the upper apparatus (2) and which is destined for the wireless terminal (3). This configuration makes the second wireless base station (1-2) possible to send the wireless terminal (3) packets received from the upper apparatus (2) before the completion of forwarding the first data from the first wireless base station (1-1).
