DATA RETRANSMITTING METHOD, NETWORK CONTROL DEVICE, MOBILE STATION AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2008/029628
Kind Code:
A1
Abstract:
A data retransmitting method includes a packet transmitting step wherein an
RNC (4) creates a packet of a desired size by using a data packet, and transmits
the packet to a BTS (2) storing the destination UE (1) of the packet, in a wireless
communication system; a reception result notifying step wherein the BTS (2)
transmits the received packet to the UE (1), and the packet reception result obtained
from the UE (1) is notified to the RNC (4); a data packet transmission result judging
step wherein the RNC (4) judges, based on the reception result, whether the data
packet that corresponds to the packet transmitted to the BTS (2) correctly reached
the UE (1); and a data retransmitting step of retransmitting the data packet,
which the RNC (4) judged not correctly reached the UE (1), through a handover destination
BTS (3), in a case where the UE (1) performed handover.
