A novel network allocation scheme in cellular networks with multiple classes of calls

In this paper, we study a cellular mobile communications network with multiple cells and multiple classes of calls. The different classes of calls have different call holding time and residence time distributions. We consider a protocol mechanism under which a blocked coil in a cell is either disconnected from the network or is deemed as a handoff call in a neighboring cell. Under this protocol, we prove that the steady state probability of this cellular mobile network has a product form. This allows as to derive explicit expressions of handoff rates for each class of calls from one cell, to another and the disconnecting probabilities for each class of new and handoff calls. Our numerical results show how these measures depend on the mobility of the mobile terminals in each cell and on the numbers of reserved channels, respectively.
