ABSTRACT:
A method and apparatus for blocking a call attempt in a CDMA system. The method includes the steps of receiving a call attempt request to be placed over a target cell of the CDMA system (202), calculating an effective load for the cell (204), comparing the effective load to a threshold (206), and denying the call attempt request by sending a denial message if the effective load exceeds the threshold (212). The apparatus includes a base station (101) and a base station controller (200) coupled to the base station (101). The base station (101) includes a plurality of transceivers (120) providing a radio communication channel and defining a target cell (130). The base station controller (200) receives a call attempt request to be placed over one of the transceivers (120) of the base station (101). The base station controller (200) calculates an effective load for the base station (101), compares the effective load to a threshold, and denies the call attempt request by sending a denial message if the effective load exceeds the threshold.
