Abstract:
1. An apparatus for transmitting a voice call via satellite from a mobile station to a destination station, comprising: a first data channel, the first data channel comprising an integrated services digital network connection; a second data channel, the second data channel comprising a mobile packet data system connection; a mobile terminal adapter that receives a voice call from a mobile station and processes the received voice call for transmission over the first data channel and the second data channel; and a first voice processing unit that inserts additional bits into the voice data when transmitting the voice data from the mobile terminal adapter to the satellite, wherein the mobile terminal adapter (1) divides the voice call into voice data and signaling data, the voice data being transmitted to and from the satellite using the first data channel, and the signaling data being transmitted to and from the satellite using the second data channel, and (2) activates the first data channel as needed for voice data transmission and deactivates the voice channel when not required for voice data transmission, and the first voice processing unit inserts an additional number of bits into the voice data to increase the data transmission rate of the voice data to one of 8 kbps or 16 kbps.
