Grade of Service (or GOS) is the probability of a subscriber finding
Congestion. Congestion means that all circuits are busy and no
Switch path is available. Thus, a higher GOS means poor Service.

A GOS 0.01 means 1 out of every 100 call is lost(or rejected) due
to congestion on circuits.

Lets assume:

X = (( Traffic in Erlangs)^ n) / n!

SIGMA Y = (( Traffic in Erlangs)^ k) / k! ; k = 0 to k=n

GOS = X / SIGMA Y

Where n = Total no. of Circuits (or channels) avaible.

Adriana,

The GOS does not depend of Technology or Manufacture. It come from other variables.

The Number of Trunks that you available, The traffic in erlang that you expect to have.

With those value you will have de GOS..

What do you think? about :

GOS = Fails + congest
—————— * 100
Calls

What is the relation between GOS ,BHCA and traffic (in Erlangs)?

How can we calculate the traffic on E1 if we know the BHCA of our system?

What will happen if on a system with BHCA rating of 1 million ,5 million subscribers are calling at a time?

Hi Joan,
GoS is basically the probability (P)of callers will be blocked (congestion). P=GoS usually % 2 for cells and GoS= %0.1.
For some callers not able to establish a call or get a service at the first attempt.

Afriana,

Yeas you are right, The gos 1% for example,

Means: for each 100 call one call will be droped.
