Abstract:
1. A method for inter-system handover, comprising: receiving a first handover-related information sent by a user terminal when the user terminal is in need of a handover; changing the first handover-related information into a second handover-related information, wherein the first handover-related information is supported by a serving communication system and the second handover-related information is supported by a target communication system; and handing over the user terminal from the serving communication system to the target communication system based on the second handover-related information; searching a table for the RFC of the user terminal supported by a target cell and an identity of a base station controller (BSC) or a radio network controller (RNC) of the target cell, wherein the table maintains the BSC or RNC of at least one cell in the target communication system and the RFC supported by the cell, and the target cell is the cell to which the user terminal is to be handed over; and changing the RFC of the user terminal in the serving communication system into the RFC searched out.
