PBGT HO : it’s a HO algorithm based in the path loss , so it starts to search in real time for cell that meet the requirments of minimum path loss .
PBGT HO its only triggered in the TCH channel and used to avoid ping pong HO in a non- dominant server , decrease over cell coverage and also it decrease the co-channel interference
PBGT HO only triggered when the path loss of adjacent cell – the path loss of serving cell > PBGT HO thrsh .
PBGT HO thrsh it’s a vender dependent but in my case
it’s take a value 4dB for urban areas
and a value of 8 dB for suburban
