low handover rate from GSM900 to GSM1800 problem
Hi everybody,
could someone tell me what are the main causes of low handover rate from GSM900 to GSM1800.
What are the main parameters that i should adjust to optimise the dual-band network ?
thanks

What is layer strategy on your network?
Multi band or dual band?

in fact their layer strategy is to give layer 2 to 1800 site and layer 3 to 900 site

Check BANDTHR if both are in same band layer some delay in HO or latch on 900 or 1800 will be side affect in this case you can have a trial for example LAYERTHR does not work properly whenever you are changing it

actually i work on huawei system, i haven't found BANDTHR and LAYERTHR in huawei system. can you explain according to huawei system
and i found something wirried they set two sites in different layer and different priorities..

You need to check Hierarchical network structure i feature in your system. In E/// it is famous as HCS in dual band strategy

Hi
In Huawei there is parameter INTELEVHOHYST (Adjacent cell inter-layer HO Hysteresis).
You should first check where the most of HO command failure is occuring. This can be done by simply querying relative counters through M2000.

hi
the most handover failuer comes from the outgoing handover in 900Mhz site (handover from 900Mhz site to 1800Mhz site)
