Abstract

The invention provides a data packet transmission / sending method used in a mobile communication system (50). In the data packet transmission / sending method, a higher-level node (1) determines to carryout switching (determining steps), a switching initiating node (2) transmits non-delivery residual data packets in a plurality of data packets to a switching goal node (3), and the higher-level node(1) sends a new data packet to the switching goal node (3) (transmission / sending steps). The data packet transmission / sending method helps keep the number of users to be held, ensure broad bandwidth and efficient line sharing at soft switching, avoid data remanence under the condition of adopting variable communication rate and prevent increase of retransmission.

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...
