Abstract:
A handover method for handing over a mobile station radio signal call connection from a serving base station to a neighboring base station of a mobile communication system, the system having a capability of providing error correction of the radio signal with different protection levels, the base stations each emitting a signal, said method comprising:measuring a characteristic of the signal emitted by each base station at a receiver of the mobile station;determining at least one possible error correction for a call connection to the neighboring base station;determining at least one first handover criterion on the basis of the determined possible error correction;comparing the signal measurements obtained in said measuring step with handover criteria including the determined first handover criterion;performing a handover from the serving base station to the neighboring base station when the comparing step indicates that the signal measurement for the neighboring station meets the handover criteria; andsetting the error correction for the call connection as the error correction of the neighboring base station.
