the gade of service is best measurment to know the quality of network , so value between 2% and 5% is good grade of service . how we calculate the grade of service of network i know from erlang table , Is there another to find out % of Grade of service .
can any body give more explanation about the GOS% .
and is it possible to get the GOS of the whole network using the ErlngB calculator .(by entering one by one the Value of Erlange of specific cell and the number of TCH channels,and then obtaining the GOS or the Blockage of that cell ,, and same of all cells in the network. then summing them all and getting the average value of all >)
Oh guys nice discusion, but i have 1 more question for you.
I have designed a network with 2% of GOS and after implemented it i got 1 cell with 51 channels making 55 erlangs, doest it mean that this cell is 15% congested, or 15% will be blocked.
