In current digital multi-site systems, an intra-cell handover is performed only when inbound link quality (as measured by a base site) degrades below a desired level and outbound link quality (as measured by a subscriber) remains at or above a desired level. Such intra-cell handovers may involve a change in the time slot on the same frequency, a change in frequency, or a change in time slot and frequency. However, there is currently no approach for performing an intra-cell handover when outbound link quality degrades below a desired level even though inbound link quality is at or above a desired level, particularly when neigh- boring site outbound link quality is also below a desired level (i.e., when an inter-cell handover does not provide any outbound quality improvement).
