HO Algorithm 1 & 2

[airian]

Dears,

is there any significant improvement when using HO algorithm 2 in huawei ?

didnt find any improvement, instead had to put a lot of time to get the stats where they were when algo1 was running. any one else found any improvement??

In the network i work we use HO II algorithm by standard as was recommended to us by Huawei engineers.
Want to see the continuing of this thread...

Hi ,

we have switched to HO algo2 because of Intracell HO.

In algo 1 urgency bad quality HO will trigger intracell HO if there is no strong neighbour cell. This leads to high number of intracell ho at low signal strength -> leads to more drops and quality degradation.

Furthermore HO algo2 allows different UL and DL Rxlev and Rxqual offsets for interference HO (another type of intracell HO). This huge advantage, because UL and DL receive levels are different because of different TX power and sensitivity levels in MS and BTS. That improves intracell HO performance further.

i had a problem after switching to HO Alg 2 that intra cell handover couters become zero, although concentric circles and UtoO OtoU are set to yes anyone faced this problem ?
Thanks
