This paper presents a simple queueing model to analyze the SMS capacity of a GSM cellular network. The analysis is based on a detailed study of GSM channels and their usage by SMS and other traffic. It is seen that SMS is sent on the same control channels that are used by voice call set-up and location updates. The results show that if SMS volumes continue to increase dramatically, the control channels used by SMS can become a bottleneck, thus increasing the blocking probability of SMS as well as voice calls.
