<p>A system and method are presented for optimally retuning channel equipment (24) in a base station (18) serving a cell (10) from a first channel group to a second channel group, without dropping pending calls and maintaining channel separation throughout the retune above a predetermined threshold. A sequential order for retuning the channel equipment is determined (62) which ensures that every channel equipment is retuned to a channel that is separated from the operating channels of each other channel equipment in a cell by a certain threshold. After determining the appropriate order, the status of each channel equipment is checked (65) to determine whether the channel equipment is busy or idle. Based on the status of each channel equipment, the channel equipments are simultaneously retuned (86) in groups of the size equivalent to the number of idle channel equipment in the determined sequential order. A pending call on a busy channel equipment to be retuned is transferred (80) to another channel equipment which is outside of the group to be retuned, using an intra-cell hand-off. The channel equipment are retuned iteratively in this manner until each channel equipment is retuned.</p> |
