  • Method for allocating a call in a CDMA base station
    Patent number: 5907543
    Abstract: This invention is directed to a method for allocating a call in a CDMA base station. Whenever the base station receives a report of the change in the transmission power from channel processors, the level of interference affecting neighboring cells by a cell of its own is measured. In addition, when a new call is attempted, upon comparing the measured level of interference with a predetermined reference level (a threshold value) of interference, it is determined whether a call is allowed (i.e, allocated) or not dependent on a distance between the mobile station and the base station.
