Abstract

The invention discloses a communication method used in a mobile communication system. The mobile communication system comprises an upper node used for sending a plurality of data packets addressing to a mobile unit, a switching initiate node used for sending the plurality of data packets addressing to the mobile unit, and a switching target node used for sending the plurality of data packets addressing to the mobile unit. The communication method comprises that: the switching initiate node allocates residual data packets and sends the allocated residual data packets to the switching target node; and the switching target node receives the allocated residual data packets from the switching initiate node and new data packets sent by the upper node, and sends the data packets according to the receiving order without considering whether the data packets are new data packets or residual data packets.

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) Apply. 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 together with...
