Abstract:
The method of utilizing a minimum cost distribution of wired network components in a cellular communication system having vocoders in a BSC (base station controller) and having a plurality of BTSs (base stations) each having channel elements, where the BSCs and the BTSs comprise a portion of a wired network, comprising, the steps of:a) computing the number of vocoders N.sub.-- VC required such that a first value of vocoder blocking probability ""b"" is not exceeded which value b is less than 1/2 the value of total allowed wired network blocking probability ""BP"";b) computing the total number of channel cards N.sub.-- CC required in all the BTSs such that a first value of vocoder blocking probability ""(BP-b)/(1-b)"" is not exceeded for any of the BTSs;c) calculating wired system costs based on the numbers last obtained for N.sub.--VC and N.sub.--CC;d) repeating, ((BP-b)/(1-b))/b additional times, steps a), b) and c) whereby a lowest wired system cost may be ascertained from examining the results of step c) and whereby ((BP-b)/(1-b))/b, if not a whole number is rounded up to a whole number; ande) providing the vocoders and channel cards for the cellular communications system based on one or more of steps a) and b) above.
