Prediction of reverse traffic load in multiple services CDMA systems
多业务CDMA系统中的反向负荷预测

In a Code Division Multiple Access (CDMA) mobile communication system which supports multiple services, such as voice, and data, the variation degree of the cell load after adding a connection is different for the services with different data rates and quality of service (QoS) requirements. Hence the cell load must be constrained to preserve the system stability. This paper presents a method for forecasting the increment of the cell reverse load after adding a new connection of a pre-defined service type. The method is then exemplified by applying it to predict the reverse load in a typical system. The results are further validated by computer simulation.
