Method and apparatus for controlling transmit power thresholds based on classification of wireless communication subscribers
First Claim
1. In a communication system having a base station, a base station controller communicating with said base station, at least one fixed location user station and at least one mobile user station, wherein users of said user stations transmit signals to and receive communication signals from said base station, a method for controlling transmission signal power of said communication signals transmitted by said base station, the method comprising the steps of:
- at said base station, receiving a current signal from said fixed user station or said mobile user station;
at said base station controller, determining if said current signal was transmitted by said fixed user station; and
at said base station, reducing a power threshold of communication signals transmitted to said fixed user station if said current signal was transmitted by said fixed user station.

Abstract
The present invention provides a method and apparatus for allowing a base station or base station controller to adjust transmissions to fixed location subscribers in closed-loop communication systems. In a closed-loop communication system, a base station exchanges signals with both fixed location and mobile user stations. When a user or subscriber initially registers with the base station, the base station determines a status of this subscriber based on, for example, an electronic serial number transmitted to the base station. The base station compares the electronic serial number to a database (Home Location Register) which determines whether the user corresponds to a fixed station or a mobile station. If the user is a fixed station, then the base station lowers nominal and minimum power level thresholds. Based on the lowered thresholds, the base station thereafter transmits forward link signals to the fixed station at a lower power level. As a result, the base station can increase its capacity due to the lower overall power rate.
