ABSTRACT:
Access noise in a spread spectrum communication system (100) is reduced by broadcasting a resource indicator message (116) from a base station (102) and is received by mobile stations (104) in the serving area (103) of the base station. The resource indicator message indicates which resources are supported (202) by the base station, as well as their present availability (204, 206, 208, 210). If a desired resource is not presently available (408), mobile stations will avoid requesting access to that resource (410). When the resource becomes available, access noise can be controlled by having mobile stations wait a randomly selected period of time (414).
