The invention relates to a special wireless chain redistribute method with refreshable activate time, used in wideband code-division complex system, wherein said method comprises that: BSC and base station process redistribution of synchronous wireless chain at Iub interface; BSC and terminal process redistribution of wireless interface; BSC and RRC layer confirms the successful transmission of redistribution message, wait T2 time, and convert to new distribution, send trigger message to the base station; base station receives trigger message, converts to new distribution, and sends descending DPCCH signal to terminal via new physical channel; when the terminal redistributes successfully, physical layer receives DPCCH signal at new channel, synchronizes descending data and informs the RRC layer, terminal converts to new wireless chain and sends wireless interface redistribution complete message to BSC. The inventive method can shorten time delay and reduce loss.
