1. A method comprising:
- a computer system monitoring actual access channel occupancy in a wireless coverage area;
detecting, by the computer system, a threshold level of actual access channel occupancy in the wireless coverage area; and
in response to detecting the threshold level of actual access channel occupancy in the wireless coverage area, the computer system automatically adjusting a quantity of access channels available for use in the wireless coverage area, wherein, in operation, each access channel available in the wireless coverage area consumes a respective Walsh code of the wireless coverage area.

Abstract
A method and system for dynamically varying the number of air interface access channels in a wireless coverage area, based on actual access channel occupancy in the coverage area. A cellular base station monitors actual access channel occupancy in the coverage area. When the base station detects a threshold level of actual access channel occupancy for a threshold time period, the base station automatically changes the number of access channels available for use by mobile stations operating in the coverage area.

20. A method comprising:
-
a computer system making a number of access channels available for use in a wireless coverage area, wherein, in operation, each access channel available in the wireless coverage area consumes a respective Walsh code of the wireless coverage area; the computer system automatically incrementing the number of access channels when actual occupancy of at least one of the access channels is greater than an upper threshold for a first designated dwell period; and the computer system automatically decrementing the number of access channels when actual occupancy of at least one of the access channels is less than a lower threshold for a second designated dwell period.
