Reply To: Erl/Sub


Hello Arian,

that’s very interesting, let’s try to solve this together…

MHT = 893 seconds.
That’s the first thing that bothers me. Of course, your erl/sub is gonna be way too high. Average MHT around the world is about 30 to 60 seconds. Average erl/sub is about 20mErl (0.02 Erl)

Can you imagine if on average, one subscriber spends about 13 minutes per call in one cell ? It is impossible. They’ll eat up their subscription fees in few days…

I believe your MHT either :
– is wrongly computed
– doesn’t represent average MHT per cell and per call
– shows a BIG problem of frozen TRX (a TCH keeps being allocated in your cell even though the call has been released)

Could you please upload some QoS excel reports (values per cell and at the busy hour) and send them to me ? (my email is (at) gmail dot com )

The “radio resource congestion”…
what is the unit ?
can you try to find the “rate of radio congestion per cell at busy hour” instead ?
include also the erlang per cell

Your BHCA is very high (4 calls / subs at BH !) .. need qos report to understand why 🙂

i’m waiting for your mail,
