Abstract
A domain handover method and system for a GSM terminal are described, a terminal protocol stack receiving a handover command from a network side, and notifying a physical layer to release a physical channel with a current cell, sending a synchronization request to the physical layer, after receiving a fed-back synchronization acknowledgement message, sending the physical layer a residence request carrying a system message of a handover target cell from the network side, after receiving a residence acknowledgement message from the physical layer, sending the physical layer a handover request carrying a handover type and a range of TA values. The physical layer judges whether to continue the PS handover or not according to a parameter carried in the handover request and the stored TA value. When continuing the PS handover, the terminal protocol stack instructs the physical layer to establish a physical channel with the target cell.
