Abstract:
In a wireless communications system that provides wireless communication services to a plurality of wireless subscriber units extant in said wireless communication system, by utilizing a plurality of variable rate speech coders that have at least one adjustable operating parameter associated with a forward radio channel and having at least one adjustable operating parameter associated with a reverse radio channel, apparatus for minimizing a total power on at least one of said forward radio channel and said reverse radio channel, comprising:means for determining an occurrence of call blockage, comprising: means for measuring a total power summed over all of said wireless subscriber units being served on said forward radio channel, means for comparing said total power on said forward radio channel to at least one threshold associated with said forward radio channel in order to determine if said total power on said forward radio channel is greater than at least one of said at least one threshold associated with said forward radio channel, means for measuring a total power summed over all wireless subscriber units being served on said reverse radio channel, means for comparing said total power on said reverse radio channel to at least one threshold associated with said reverse radio channel in order to determine if said total power on said reverse radio channel is greater than at least one of said at least one threshold associated with said reverse radio channel; and means, responsive to said occurrence of call blockage, for adjusting at least one of said at least one adjustable operating parameter associated with at least one of said forward channel and said reverse channel, whereby a resulting call carrying capacity of said wireless communications system is increased.
