Different Techniques for Successful Handoff and Prevention of New Call Blocking Probability

Abstract

The unsuccessful handoff and call dropping have been a fast growing, challenging and interesting area in real time application. The immense advancement in cellular networks communication study, has made tremendous improvement in the sphere of wireless technologies which are complementary to other and their union for specific area and services has created single wireless network system. The different wireless network systems having separate function have been combined under the concept of Next-Generation Wireless Communications Systems (NGNS) with a view to provide seamless high-quality wireless network services to mobile users. A set of mechanism are proposed for successful handoff process during the transfer of active calls or date session from one cell in a cellular network to another or from one channel in a cell to another maintaining uninterrupted service to a data session user. In this paper factors responsible for unsuccessful handoff and new call dropping probability method with probable control measures are reviewed. Methods are also proposed to increase handoff performance of mobile IP by decreasing the probability of false handoff initiation to a great extent under handoff management protocol of NGWS considering MT speed and handoff signaling which are directly proportional to false handoff initiation. In is reported that electromagnetic radiation is reduced to a considerable limit with the use of multi antennas instead of a single big antenna.
