Method and system for increasing frequency assignment in a mobil telecommunication system

A method for adding a new frequency assignment (FA) in a cellular communication system of the type having a plurality of cells with each cell containing a plurality of sectors and each sector having a group of frequencies assigned to it that is the same as the group of frequencies assigned to other sectors within that same cell, a plurality of base stations each generating a channel list having a plurality of identifiable location for various frequencies, and a least one mobile station for communicating with at least one of said base stations on a channel frequency selected from said channel list for said one base station, wherein a current channel list is based on program loaded data (PLD) containing system configuration information such as the current channel quality, current channel frequency assignments (FAs), and the number of unassigned channels, said method comprising the steps of:

• (a) transmitting communication signals between said one of said base stations and said at least one mobile station via a frequency selected from said current channel list;
• (b) receiving a request for a new FA at said one of said base stations from said at least one mobile station;
• (c) generating a new channel list identifying only said new FA;
• (d) optimizing whether channel signal quality of said new FA selected from said new channel is acceptable;
• and,
• (e) generating a combined channel list including information from both said current channel list and said new channel list, for transmitting communication signals between said one of base stations and said at least one mobile station through a frequency selected from said combined channel list.
