Handover can fail beause of not reachable base station in network domain and rss is not greater and no base station in coverage area network. not adequate bandwidth avaliable can cause failure of handoff.

there are several reasons for handover failure
1> due to not availibility of TCH/SDCCH at new station.
2> Due to far distance between two BTS .
3> Due to TRX is not supporting.
