A new channel borrowing assignment scheme: teletraffic performance evaluation through discrete event modeling in a mobile cellular environment

Abslracl-Frequency planning in cellular systems becomes more and more critical as cell dimensions dcercase. To address this issue a new channel borrowing assignment scheme based on compact patterns is prescntcd in this research, which allows the borrowing of resources in an adaptive way depending on the traffic conditions. By using efficient techniques in inter-cell and intcra-cell reallocalion phase of the presented scheme. its teletraffie performance has been further improved. This scheme does not require system-wide information and all it needs is information about thc local cell and its intcrfcring CCIIE. As fundamentally a main objective ofthis research >Vas study of user’s mubility efferl on performancc of channel assignment strategies in a microccllular scenario, an innovative simulation environment using discrctc time step model traffic simulator notion has becn developcd and exploited for ertrdcting as rCalistie as possible results regarding tcletvaflic pcrformancc of the proposed scheme.
