Abstract

La presente invencion se refiere a un sistema de comunicaciones que proporciona medios para controlar dinámicamente desempeño del sistema durante tiempos cuando el tráfico de comunicaciones cambia substancialmente para evitar bloquear el servicio mientras que mantiene calidad de comunicaciones. El sistema de comunicaciones proporciona este control dinámico para comunicaciones de voz y/o video. Por ejemplo, un sistema proporciona medios para incrementar la capacidad de voz efectiva durante tiempos de tráfico de voz incrementados en un área de servicio determinada, y disminuir la capacidad de voz efectiva durante tiempo de tráfico de voz disminuido, en donde el decremento en la capacidad de voz efectiva proporciona un incremento en la calidad de voz. En una modalidad ilustrativa, cuando el tráfico de voz se incrementa a un nivel umbral determinado, el sistema implementa compresion de habla en canales selectos para incrementar la capacidad efectiva a esa área de servicio. En otra modalidad, el sistema combina dos canales comprimidos en uno para incrementar la capacidad efectiva aun más.
