Abstract

A packet transferring / transmitting method is provided for use in a mobile communication system 50 . In this packet transferring / transmitting method, an upper node 1 determines the implementation of handover (determination step), and a handover addressing node 2 transfers, of a plurality of packets, a non-transmitted residual packet to a handover addressed node 3, and the upper node 1 transmits a new packet to the handover addressed node 3 (transfer / transmission step). This enables maintaining the number of users to be accommodated while securing a wide bandwidth, sharing a line with high efficiency at soft handover, avoiding data residual in the case of the employment of variable communication rate, and preventing an increase in retransmission.

Description

technical field

[0001] The present invention relates to the soft handover in the high-speed large-capacity communication process in the W-CDMA (Wideband-Code Division Multiple Access: Wideband CDMA) system, more specifically, relate to be suitable for DSCH (downlink public channel) and HS-DSCH (high speed downlink channel) Public channel) data packet transmission / transmission method and mobile communication system. Background technique

[0002] In recent years, the CDMA mobile communication system has been developed rapidly. In addition, commercial services based on the W-CDMA system have also started, which enables transmission / reception of large-capacity data such as moving images together with voice and still images included in current main services. Under such circumstances, as a standardization group for the third generation mobile communication system, 3GPP / 3GPP2 (Third Generation Partnership Project / Third Generation Partnership Project 2) is organized, which aims at ...
