ABSTRACT:
A communications system providing a means for dynamically controlling system performance during times when communications traffic substantially changes to prevent blocking service while maintaining communications quality. The communications system provides such dynamic control for voice and/or video communications. For example, a voice communications system according to the present invention provides a means for increasing the effective voice capacity during times of increased voice traffic in a given service area, and decreasing the effective voice capacity during time of decreased voice traffic, wherein the decrease in the effective voice capacity provides an increase in voice quality. In one illustrative embodiment, when the voice traffic increases to a given threshold level, the system implements speech compression on selected channels to increase the effective capacity to that service area. In another embodiment, the system combines two compressed channel into one to increase the effective capacity even further.
