In Huawei,there are many access paramters based on TA.
1.MAX TA—Similar to MAX TA of ericsson
2.TA threshold.—-similar to TALIM in Ericsson.
But there is another parameter “TA emergency HO threshold” in case of concentric cells.
TA emergency HO threshold should be > TA threshold.
There are various other access parameters in Huawei based on TA.
I didn’t came across any reserved parameter for BSC6000.However,i was unfortunate as i didnt worked on BSC3200(i think its the newest version)
