Any cell of a network experiences two types of call arrival; new originating call, and handoff call from surrounding cells. If the number of busy users around a cell is finite with an average value of N, then rest of the radio resources of the network can be assigned to support handoff calls. So, for handoff calls, the traffic case resembles a network with limited user traffic (PCT-II), where as rest of the radio resources handle unlimited user traffic (PCT-I). In this paper, a mixed traffic model (combination of PCT-I and PCT-II) has been considered to evaluate different traffic parameters like, probability state and call blocking of a cellular network. For analysis, here, two-dimensional state transition diagram as well as tabular method is considered.
