Abstract:
A system and method are presented for optimally retuning channel equipment in a base station serving a cell 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 which insures 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 to determine whether the channel equipment is busy or idle. Based on the status of each channel equipment, the channel equipment are simultaneously retuned 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 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.
