Abstract
Abstract A channel resource utilization level associated with a particular cell area is continuously evaluated against a predefined threshold value. The imposed threshold value indicates the minimum level of channel resource utilization desired by the serving mobile telecommunications network. In response to a determination from the evaluation that a particular cell area is being under-utilized, a message indicating that a reduced air-time rate is being offered is broadcast to all mobile stations currently traveling within the affected cell area.
