Model of the cellular network servicing multicast connections in Iub and WCDMA resources

In this paper a new analytical method of blocking probability calculation in multi-service cellular systems with multicast connections is proposed. The new analytical method considers the influence of both the WCDMA and Iub interfaces for traffic streams service characteristics. The basis for the discussed method is a model of the full-availability group with traffic compression and the fixed-point methodology. The results of the analytical calculations of the cellular system with multicast connections were compared with the results of the simulation experiments, which confirmed the accuracy of the proposed method. The proposed scheme can be applicable for a cost-effective resource management in UMTS/HSPA/LTE mobile networks and can be easily applied to network capacity calculations.
