the user requests a new channel from the new cell so that it can continue its communication. This is known as a handoff call. Assume that each cell has e channels, and each channel can only be assigned to one user/call at a time. When all the channels in the new cell are being used (i.e., all channels are being assigned to ongoing calls), the handoff call has to be terminated or blocked. That is, the new base station servicing the new cell cannot allocate a channel to the handoff call. Assume the interarrival time between any two consecutive calls is exponentially distributed with mean , and the channel holding time (i.e., call duration) is also exponentially distributed with mean . The objective of this problem is to derive the blocking probability of a handoff call to the new cell.
