Claim:
1. A method for determining a delay difference, comprising: a serving cell receiving information of time which is measured by a neighboring cell and at which uplink channel/signal information of User Equipment (UE) for determining a synchronization delay is received; and the serving cell determining a synchronization delay difference between the UE to the serving cell itself and the UE to the neighboring cell according to information of time which is measured by the serving cell itself and at which the uplink channel/signal information of the UE for determining the synchronization delay is received, and the information of time which is measured by the neighboring cell and at which the uplink channel/signal information of the UE for determining the synchronization delay is received; wherein the uplink channel/signal information, which is measured by the serving cell, of the UE for determining the synchronization delay is the same as the uplink channel/signal information, which is measured by the neighboring cell, of the UE for determining the synchronization delay.
