Abstract
A cellular capacity in a multimedia DS-CDMA system may be maximized by controlling a transmission rate of data calls. In a method for maximizing the cellular capacity, the total interference quantity is controlled by restraining the transmission rates of the respective data calls according to diminution factors of a linear, a parabola and a hyperbola; the transmission rate of the data call is increased in case a traffic load is small; and the transmission rate of the data call is decreased in case the traffic is overloaded, thereby more calls can be received and the number of subscribers having a service of voice and data calls in the CDMA circumstances may be allowed most suitably. In case a call of higher priority is newly received under a state that the data call of a high speed occupies a resource of a system for a long time, the transmission rate of the currently progressing data is controlled to receive the new call. Accordingly, the number of subscribers can be allowed at maximum by controlling the transmission rate of the data call so that more voice and data calls may be received within the CDMA system capacity.
