Steps in a handoff:
1.)Starting in a state where only one cell is supporting the call in question.
2.)Informing the candidate cell of the imminent handoff
3.)Signaling the mobile to begin executing the handoff.
4.)New cell beginning to service the mobile
Mobile beginning to use the new cell
5.)Entering the mid-handoff state (prolonged only in CDMA)
6.)Mobile discontinuing use of the old cell
7.)Old cell stopping service to the mobile
8.)Ending in a state where the new cell is supporting the call in question

We have different types of Handoff Procedures depending upon the situation,
1. Soft Handoff: Soft Handoff is when the mobile goes from one cell to another cell but uses the
same frequency. We also can have softer handoff when the mobile goes to a different sector
within a cell.
2. Hard Handoff: Hard Handoff is when
i. MS is transferred between disjoint active sets
ii. CDMA frequency assignment change
iii. The frame offset changes
iv. When the mobile is sent from CDMA channels to analog voice channels.
3. Idle Handoff: When the Paging Channel is transferred from BS to another BS
4. Access Handoff: When the mobile sends the access attempts to another BS.

Handover procedures have, until now, varied widely and have not always done .... for filing information, it is often useful to explain it to the new person. ...
