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 wireless communication.

This paper has gives the details of Handoff, and Different
parameter required for enhance the Quality of Service in
wireless communication. As communication has become
the fundamental need for the human society, for this
continuously no of user in the given cell area is increasing
day by day, and a problem of handoff is occurring.
Without much effecting the Quality of Service in
communication how one can improve the quality of
handoff this paper describe in details the previous study of
handoff and latest work on the same. Paper also describe
thoroughly 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.
