Patent ID: 6999772

Claim:
A channel assignment method for multi-FA (Frequency Assignment) CDMA cellular systems in which a base station communicates a plurality of mobile stations, said method comprising the steps of: comparing a first threshold value with a cell loading factor of a first FA when the base station receives a new call request in said first FA; assigning a first traffic channel in the first FA, if the cell loading factor of said first FA is less than the first threshold value, otherwise searching for a second FA of which the cell loading factor is minimum; comparing a second threshold value with the cell loading factor of the second FA; and assigning a second traffic channel in the second FA, if the cell loading factor of the second FA is less than the second threshold value, otherwise rejecting the request; wherein the cell loading factor of each of the first and second FAs is determined by the following equation: cell loading factor=1−thermal noise power/received power.
