This is happens because roaming system and handoff process makes the world in a hand. For that, by the help of that two systems people can join with the communication field from any position in the world. However, one hand the cell user feels happy for getting benefit from roaming system, on the other hand, traffic fall them in a problem, because it makes the handoff call drop, and so, the people cannot get idle recital from the roaming system. on the other hand the performance of roaming system depend on the number of successful handoff calls, but unsuccessful handoff request happens when there is no available idle channel in the system. Therefore, this research paper has shown by his simulation result, that, reserved channel will effect very positively for more reduce the handoff fall probability, and this study has done this experiment by Reserved Channel Allocation (RCS) and Markov Chain Model.
