Abstract

A mobile auxiliary communications facility for use with a satellite-equipped communications link and a gateway hub. The satellite-based communications link is adapted to provide one or more Internet Protocol (IP) communication pathways between a first location and a second location. The gateway hub, situated at the first location, is coupled to a terrestrial data network and also to a terrestrial telephonic network. The mobile auxiliary communications facility of the present invention includes a utilization mechanism for utilizing the IP communication pathways to implement one or more bi-directional telephonic communication links and one or more bi-directional data links between the first location and the second location. The mobile auxiliary communications facility is equipped with a conversion/deconversion mechanism and a bandwidth allocation, multiplexing and demultiplexing mechanism. In operation, the mobile auxiliary communications facility is deployed to a second location which represents a site that does not have access to a terrestrial communications network, a site where access to a terrestrial network has been interrupted, and/or a site where a terrestrial network is not functional. The conversion/deconversion mechanism converts voice, speech, and/or audio signals into a packet format compatible with standard Internet Protocol (IP) data transmissions. The bandwidth allocation, multiplexing and demultiplexing mechanism allocates the available bandwidth of a communications link by combining voice and data packets into a single composite IP data channel. This combination process is performed in accordance with usage, demand, and/or a set of quality of service (QoS) prioritization parameters. The bandwidth allocation, multiplexing and demultiplexing mechanism responds to a momentary lack of voice activity by temporarily reducing the number of voice IP packets on the composite IP data channel.
