ABSTRACT:
The load on the communications resources of a cellular telephone system is monitored to detect instances of excess amounts of unused resource capacity. When such instances are detected, a message is transmitted to subscribers via the cellular system offering reduced charging rates for calls initiated in response to the offering message. The subscriber mobile stations are programmed to alert the subscriber to the broadcast of the offering message, after which the subscriber may initiate a reduced rate call. The mobile stations may further be programmed to automatically initiate the cellular call in response to receipt of the offering message, and to thereafter engage in the communication. Monitoring of communications resources external to the cellular system is also made, and an offering message is broadcast by the system in response to detection of excess amounts of unused external resource capacity, in response to which subscribers may initiate calls requesting reduced rate access to the resource.
