Abstract
The system for increasing the call capacity of a wireless communications system degrades voice quality of the communications connections within a predetermined limit in order to increase the efficiency of the available RF spectrum as measured by the call carrying capacity of this allocated RF spectrum. This is accomplished by adjusting the transmission rate of the speech coder at the mobile subscriber unit and/or the speech coder that may be located at the mobile switching center so that the call carrying capacity of the wireless communications system is therefore increased. Additionally, the situation of call blocking is monitored to determine if frame error rate targets should be adjusted to further increase the call capacity. At times when the wireless system is not experiencing peak usage, the voice quality is restored to normal levels. The term “mobile subscriber unit” does not imply that the mobile unit is restricted to a moving vehicle. The present state of the art includes the use of mobile subscriber units in fixed wireless applications as an alternative to traditional wire telephony services.
