Abstract

The invention relates to a data packet transmitting / sending method and a mobile communication system. In the mobile communication system, residual data packet data of a first base station is transmitted to a second base station by switching processing executed according to the migration of a mobile station. The mobile communication system comprises a control unit which is used for executing transmission but not executing packaging processing for appending a beginning of message for retransmission control to the residual data packet data, wherein the mobile station comprises a receiving unit for receiving the transmitted residual data packet data.

Description

[0001] This application is a divisional case of the original patent application number 02829656.7 (international application number: PCT / JP2002 / 009763, filing date: September 24, 2002, invention name: data packet transmission / sending method and mobile communication system) Application. technical field [0002] 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 [0003] 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 togethe...
