HANDOVER METHOD AND SYSTEM

摘要

Disclosed are a handover method and system; the method comprises: when a cross packet data serving node (PDSN) handover occurs to a terminal in a code division multiple-access (CDMA) system, and after a P-P interface connection is established between a source PDSN and a target PDSN, the source PDSN and/or the target PDSN publically announces that the target PDSN is to receive the downlink data of the terminal; when the target PDSN receives the downlink data of the terminal, the target PDSN sends the downlink data to a target radio access network (RAN) or to the target RAN and the source PDSN. Utilizing the present invention, data forwarding during cross PDSN handover is realized, and problems such as data stream route bypass caused by a fixed anchor point are avoided.
