Possible solution for traffic in roaming system

Day to day the area of communication is growing up dramatically by the help of modern technology such as Mobile Communication is one of them. Moreover, Wireless Communication is one of the most powerful communication sector who makes the world small and globally because roaming system and handoff process both system has able to work together. As a result, it is not a problem for a cell user to get communication link from anyplace and any time. Again, in many situation handoff failures and unnecessary handoff are triggered causing degradation of quality of service. Moreover, data traffic created by several reasons but, commonly it happens from unnecessary handoff call by hard handoff technique that makes the system busy. Therefore, Global System for Mobile Communication (GSM) has effected by “Ping-Pong” problem. So, it is need to take more attention for remove that problem from the mobile network. However, in the environment of macro cellular system, one of the most popular models for signal strength prediction is Hata-Okumura model, and by that model this paper has calculated the strength of received signal with respect to the distance, and the result has adopted to reduce the several number of handoff call.
