Call processing overload at a base station of a cellular wireless network is controlled by monitoring a level of call processing at the base station, and reducing a present handoff rate for active users when the call processing level exceeds a first threshold less than a maximum call processing capacity. When the call processing level at the base station exceeds a second threshold greater than the first threshold, a present rate of call originations or terminations is reduced while further reducing the handoff rate.

[ We claim:] [1.]1. A method of preventing an overload of call processing capacity at a base station of a cellular wireless communication system, comprising:monitoring a level of call processing at the base station with respect to a maximum call processing capacity of the base station, wherein said call processing capacity includes processing of call handoffs, call originations and call terminations handled by the base station;setting a first call processing threshold which is less than the maximum call processing capacity of the base station;setting a second call processing threshold which is greater than the first call processing threshold but less than said maximum call processing capacity;reducing, in a first phase, a present handoff rate for user stations served by the base station when the monitored level of call processing exceeds the first threshold; andwhen the monitored level of call processing exceeds the second threshold,reducing, in a second phase, a present rate of at least one of the call originations and call terminations handled by the base station, while further reducing said handoff rate.
