Abstract:
A method for dynamically adjusting the output power level in each active voice and data transmission channel of a multichannel mobile cellular to satellite communication system, the power levels of the voice and data channels being preset to appropriate initial output power levels, the initial power level for data channels being higher than the initial power level for voice channels, said method comprising the steps of:receiving a call request from communication equipment on one of the plurality of channels; determining for said call request whether the call is a voice call or a data call; determining whether a transmission channel is available for said call; assigning said call to an available voice or data transmission channel; looking up pre-stored power parameters for each active transmission channel, wherein looking up prestored output power parameters for each of said active transmission channels comprises looking up of parameters based upon a number of active data and voice transmission channels, a minimum power required for each call type based upon an allowable bit error rate, and a maximum safe output power of a high power amplifier; transmitting said parameters to each said active transmission channel via a message; and dynamically adjusting the output power of each said active transmission channel in response to said transmitted parameters, whereby a combined adjusted output power of the active transmission channels will not violate the integrity of the amplifier.
