How one cell utilization can be above 100% . If 100% resources are busy then how can it shows above 100% ..Bijoy / Pix pls help
Guru
Few aspects about utilization
1.Are you talking of full rate TCH utilisation.But if your Half rate is enabled,then obviously your utilisation will be higher.
2.Utilisation talks about the resource busy time in regards to the GOS of the system.Now,how do you calculate your equppd erlang?Its through ErlangB with 2% gos,Now if there is high tch blocking in the cell,you gos will increase ,& so will be your utilisationBr\\
BijoyHi bijoy,
1) both full rate & half rate
2)Earlang B with 2% gos
Can you elabrote more plsBijoy i got the answer from some other previous session.Thanks ,do’t want to waste your time..Thanks
Guru
i really appreciate that
thnxAlso remember that according to Erlang B 8 channels at 2% blocking gives 3.627Erlangs. However, if 8 channels are occupied for an hour, it generates 8 Erlangs . Since 1 Erlang is defined as occupation of 1 radio channel for 1hour.
how to calculate traffic handling capacity of any bts of 2g in gsm.also methods to increase efficiency of bts
Hi Guru/ Bijoy,
What is the answer you got from another session?
I also require to know why cell utilisation is above 100% for blocking probability higher and number of channels higher.
Thanks
Hello
Abou Utilization %
According to the Ut formula that we used ir is normal to get more than 100% boz we used generate traffic /erlang b table teaffic gos 2%
And the rule that you can check your data generate traffic should be less than or equal tch numberBlocking in telecommunication systems is when a circuit group is fully occupied and unable to accept further calls. Terms used are Blocking and non-blocking switch.
Grade of Service – GOS – term from the Analog era that was used to help with Switch and Circuit dimensioning.
