Introduction
Basically, Handover means the giving of control
of or responsibility for to someone else.
Similarly, The process of changing point of
communication while communicating is known
as handover in cellular network.

4. Handover Decisions
There are numerous methods for performing
handoff. From the decision process point of
view, one can find at least three different kinds
of handoff/handover decisions.
Network-Controlled Handoff
Mobile-Assisted Handoff
Mobile-Controlled Handoff

5. Network-Controlled Handoff
Network measures the transmission quality
via base stations and decides when handover
should be executed.
In general, the handover process takes 100-
200 ms.
Network-controlled handoff is used in first-
generaion analog systems such as AMPS
(Advanced Mobile Phone System), TACS
(Total Access Communication System), and
NMT (Nordic Mobile Telephone).

6. Mobile-Assisted Handoff
In a mobile-assisted handoff process, the MS
makes measurements and the network makes
the decision.
In the circuit-switched GSM (global system
mobile), the BS controller (BSC) is in charge of
some functions including handoff management.
The handoff time between handoff decision and
execution in a GSM is approximatelyy 1 second.

7. Mobile-Controlled Handoff
In mobile-controlled handoff, each MS is completely
in control of the handoff process.
This type of handoff has a short reaction time (in the
order of 0.1 second).
A handoff can be initiated if the signal strength of
the serving BS is slower than that of another BS.
