摘要: Balancing of loading cells in a cellular mobile radio telephone system is performed by periodically determining the channel utilization each cell, computing representative voice occupancy level, and attempting to hand-off calls from with higher channels levels adjacent lower levels. Voice are measured compared threshold values, results comparisons used direct enter predetermined states. In one state, complete cell blockage prevented directing cells. another preserved for incoming hand-offs deny access transceivers initiating new calls. Cells may assume combined stage wherein both these functions simultaneously. selected as candidates initiated more evenly distribute throughout accordance state (i.e., level) signal strength at attempted be handed off.
