Reply To: Switch Planning for GSM

Peter HANA

Dear experts,
I have 02 quetions.
1. In switching exchange, we refer to the BHCA (means number of calls in busy hour), is that right? How can we define this parameter? Or how can we calculate this?
2. Erl: What is the basic of this parameter? How can we define this?
For example: Normal subcribers have 0.01 – 0.03 Erl. Where does this result from?
Thks a lot.
