Abstract In a Code Division Multiple Access (CDMA) mobile communication system which supports integrated services, such as voice, data, and images, the variations of the forward transmit power of a base station after adding new connections are different for the services having different data rates and Quality of Service (QoS) requirements. Hence the forward transmit power must be constrained to preserve the system stability. This paper presents a method for forecasting the forward transmit power after adding a new connection of a predefined service type. The method is then exemplified by applying it to predict the forward transmit power in a typical system. The results are further validated by computer simulation.
