Handover i ett mobilkommunikationssystem

摘要

The invention relates to a handover method in a mobile communication system in which error correction of a radio signal can be arranged with different protection levels. The method comprises measuring the signal level and/or quality of neighbouring base stations (BTS) at a receiver of a mobile station (MS), comparing the measurement results thus obtained and other variables of the connection with handover criteria, and performing a handover from the source cell to the target cell, when the pre-set handover criteria are met. The method of the invention is characterized by determining at least one error connection possible for the connection in a potential target cell for the handover, determining at least one handover criterion on the basis of the determined error correction of the potential target cell, and setting the error correction of the connection in the target cell (BTS2) as said error correction of the base station of the target cell. The invention further relates to a mobile communication system for performing handover.
