As we know, Handoff is an important task in maintaining the continuity of call in cellular systems and its failure can result in ongoing call termination. As mobility in wireless cellular communication systems is its backbone, so as to enhance the quality of service (QoS) & to maintain the continuous service for users to providing a ubiquitous coverage. In this paper a brief description about the different handoff techniques in cellular systems (GSM, CDMA) moreover it compares all the handoff strategies on the basis of traffic, execution time, S/I ratio, RSS (Relative Signal Strength), call handling difficulty, handoff made and generation methods. Paper also finds the brief comparison between all handoff strategies which are used in mobile communication.

Horizontal Handoff

Vertical Handoff

Hard Handoff

soft handoff



We have thoroughly studied handoff strategies and have learned, that handoff is the process where changing the channels like frequency, time slot, spreading codes or combination of them, are associated with the current connection during a call. The service of wireless communication depends on the handoff strategy. Here we can find out, which handoff strategy is suitable for the call continually. Above discuss the all handoff strategies where it shown that which handoff is required suitable parameter to minimize the handoff, so in above discuss, it has been cleared that the soft handoff occurred in the vertical handoff where all the parameters have been discussed.
