The paper presents a model of a group of cells, exploiting the effects of connection handoff between cells, aimed at increasing the traffic capacity of a system. The analytical model proposed is based on the model of limited-availability group, which makes it possible to determine basic traffic characteristics in the system under consideration. In the paper it is applied the generalized model of the limited-availability group, i.e. the group which consists of separated transmission links of various capacities. The results of analytical calculations of blocking probability in a group of UMTS cells were compared with simulation data, which confirmed high accuracy of the proposed method.
