Abstract:
1. A method for providing timing information for inter-system handover by an asynchronous base station in a mobile communication system including an asynchronous mobile communication network associated with at least one asynchronous base station using independent synchronization, and a synchronous mobile communication network associated with at least one synchronous base station using synchronization matched with a satellite time, the method comprising: acquiring information on the satellite time by the asynchronous base station, the asynchronous base station generating a base station frame number (BFN) synchronized to the satellite time and a system frame number (SFN) having a predetermined offset for the BFN for each cell; generating a system information block including a difference value between the BFN and the SFN; and transmitting the system information block over a common channel along with the SFN from the asynchronous base station.
