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...
In this paper a new analytical method of blocking probability calculation in multi-service cellular systems with k-cast connections is proposed. The discussed method is based on the full-availability group servicing PCT1 and PCT2 multirate traffic streams and the fixed-point methodology. The results of the analytical calculations were compared with the results of the simulation experiments, which...
The paper proposes an analytical approach to blocking probability calculation in the UMTS network carrying a mixture of multi-rate traffic, under the assumption that the part of resources of the interface is dedicated for servicing handoff traffic. In the proposed method, handoff connections are modeled on the basis of the fixed point methodology and dynamic reservation. The results of analytical...
The paper presents the application of a new analytical model of the full-availability group carrying a mixture of different multi-rate traffic classes with compression property for modeling the WCDMA radio interface with packet scheduling. The proposed model can be directly used for modeling of the WCDMA interface in the UMTS network servicing different traffic classes with and without compression...
The paper presents an approximate method for modeling of the WCDMA interface in the UMTS network in which the mobile operator introduces priorities and user differentiation. In our considerations we use a model of the full-availability group servicing multi-rate traffic with priorities for services. In the proposed model we assume that user priorities and the priorities for classes of services are...

The paper presents a new analytical method for blocking probability determination in the interface of the UMTS network. In our consideration we use a modified model of full-availability group with multi-rate traffic. The proposed scheme is applicable for cost-effective Iub resource management in 3G mobile networks and can be easily applied to network capacity calculations.
