Abstract:
A method for determining whether to perform handover of a UE apparatus to a candidate cell and carrier frequency of a TD-CDMA telecommunications network (such as a TD-SCDMA network) based separately on coverage and capacity, using one decision metric for coverage (e.g. based on received signal code power for the candidate cell and carrier frequency) and a different decision metric for capacity (e.g. based on a quantity proportional to the received signal code power for the candidate cell and carrier frequency and inversely proportional to a measure of total interference in the candidate cell on the carrier frequency. Corresponding equipment and a computer program product are also provided. In deciding whether handover is needed based on capacity, a threshold for received signal code power may be used in addition to the metric for capacity.
