is there anybody to help me, how I can calculate(counter_formula) the PDCH Utilization in Alcatel_B10 systems.Which counters are affected?
Thank you in advance14th July 2009 at 11:30 #57924PixGuest
what is your definition of PDCH utilization ? if it is an alcatel indicator, you are able to find its formula in NPO.
If it’s your own indicator, you have to define the formula yourself, or at least define what it means.15th July 2009 at 06:46 #57925totoGuest
Hi Pix, may be my question was not so correct…I want to know how to calculate the PDCH load in Alcatel_B10 systems..15th July 2009 at 08:18 #57926PixGuest
But my question remain correct 🙂 If PDCH Load is “your” indicator then it’s up to you to define it.
If you’re referring to an existing ALU (Alcatel-LUcent) indicator, then you will find the formula in NPO:
Slave PDTCH downlink occupancy per cell.
Reference: maximum number of PAGCH/PDTCH/PACCH blocks that can be sent considering the cumulative time during which PDCH(s) (slave ) are established and carry at least one UL or DL TBF.
( (P350a) / (12 * (P38e) * 4.166666667))
or in other words:
GPRS_DL_RLC_block_PDTCH / (12 * GPRS_PDCH_limited_DL_traffic_time * 4.166666667)
… and in uplink:
( (P350b) / (12 * (P38f) * 4.166666667))
or in other words:
GPRS_UL_RLC_block_PDTCH / (12 * GPRS_PDCH_limited_UL_traffic_time * 4.166666667)15th July 2009 at 11:36 #57927totoGuest
thank you for answer..
In all, my idea was to calculate how is the average load for the PDCH’s per cell for one or two weeks, i.e. how much is the percentage of usage(load) of this PDCH for this period.
Unfortunately for the moment I can’t use NPO and I can’t see the counters for this parameters.My idea is to write formula in our SQL data base and for this I’m looking for counter which are affected in this..15th July 2009 at 12:01 #57928PixGuest
Ok, i understand. In the formula below you can see the counters which are used : “P350a”, “Pxx” etc15th July 2009 at 13:20 #57929totoGuest
Hi Pix, thank you..
Is’t possible to explain me what is the meaning of this multiple “12*”and “*4,1666667”..Sosorry for my stupid question but I want understand formula and edit for period of 2 week.15th July 2009 at 17:30 #57930PixGuest
Com’on !! your questions are not stupid at all.
but you are really very very lazy. I’m sorry to be so harsh, and i don’t mean to be mean… but really…
Do you have any gprs background ?
do you understand the meaning of each counter Pxx in the formula ?
I let you find out by yourself 🙂
12 = ???
4.6666 = ???
such numbers are found ony once in GPRS/GSM.
Tomorrow evening i will answer 😛21st September 2010 at 06:58 #57931NunoGuest
