Abstract

Purpose of this paper is to propose a new strategy for the Time Slot selection in a TD-CDMA system. Indeed, in case of mixed services (like Speech and Web), the Call Admission control does not take into account that these both services could be incompatible in the radio point of view, incompatible meaning that the impact of one service on the another one is not negligible resulting for instance in an increase of the Frame Error Rate for the most sensitive service. In order to select the same Time Slot for two incompatible services, this paper proposes a new Time Slot selection in a TD-CDMA system based on the following parameters: interference level, number of available codes and compatibility between services.
