Q & A on Huawei Handover problems.

[NILCTG]

Hello Friends:

Any one working with Huawei equipment probably would agree that Huawei’s HO algorithm is complicated & not very well documented. Here I share a compilation of 60 Questions along with answers provided from Huawei HQ on HO alg(GSM). Some sample Q are:

1. How to avoid ping-pong handover between the overlaid subcell and underlaid subcell in the concentric cell?

2. How to set 2G/3G handover parameters?

3. Why intra-cell handovers happen in a cell where the intra-cell handover function is closed?

4. What is the relationship between the time of the minimum time interval for the TCH handover and the time for the filter? When does the filter have a valid output?

5. 70. What is the restriction on the deployment of COBCCH?

6. What are the differences between the load handover band and load handover bandwidth?

7. Between what channel types may the conversion trigger an intracell forced handover?

8. Why does PBGT Handover Happen only Between the Two Cells That has the Same Layer and Level? How is PBGT Handover Realized According to Huawei Algorithm?

9. If both the load handover threshold and the half rate adjust threshold are 80% according to BSC data configuration, which one is enabled first when the load reaches 80%?

10. The equipments area are all Huawei equipments. The level for the 900MHz cell is -58 dBm, and the level for the 1800MHz cell is -80 dBm. MS started conversation in 900MHz cell first, but it still handed over to an 1800MHz cell. Is this handover normal?

Hi Guys,
Need some explanations regarding the overlaid and tne underlaid cells, what is the benefits of the relevant HO and how the Trxs are configured accordingly

Thanks in advance
