Huawei GSM dualband layer algorithm

[forscherau]

here the corrected algorithm, was translated wrong in some other documents

The 14th bit: Layer HO threshold adjustment bit, The 15th/16th bits are reserved
The 14th bit show candidate cells which are better cell or not, if it is better cell, the load and layer should be considered;

If the 14th bit of serving cell or neighbor cells is 0, then the 5th – 13th bit are set to 0; it means that layer, load and share MSC/BSC don’t consider, only 1th - 4th

Criterion
Serving cell: RX_LEV_DL >= Inter-layer HO Threshold (s) – Inter-layer HO Hysteresis/ LEVHOHYST (s), bit 14th is set to 0; At the same time, bit 5th- 13th bits are turned off.
Neighboring cell: the condition A
a: the neighbor cell and the serving cell are the same layer.
1. when the serving cell is 0, if the neighbor cell get the following formula, it set to 0, otherwise it set to 1; RX_LEV_DL (n) >= Inter-layer HO Threshold (n)- Adjacent Cell Inter-layer HO Hysteresis / INTELEVHOHYST (s-> n) +64,
2. when the serving cell is 1, if the neighbor cell get the following formula, it set to 0, otherwise it set to 1; RX_LEV_DL (n) >= Inter-layer HO Threshold (n)- Adjacent Cell Inter-layer HO Hysteresis / INTELEVHOHYST (s-> n) + Inter-cell HO hysteresis(s-> n)
b: the neighbor cell and the serving cell are not the same layer, if the neighbor cell get the following formula, it set to 0, otherwise it set to 1; RX_LEV_DL (n) >= Inter-layer HO Threshold (n)+ Adjacent Cell Inter-layer HO Hysteresis / INTELEVHOHYST (s-> n)
If the above criterion is not met(Neighboring cell), then bit 14th is set to 1.
At the same time, bit 5th- 13th bits are set to 0.
