Paging KPIs

[justdream]

Dears,

Could you share 2G Paging KPIs with exact counters name (from Radio side)

[asifhaider919]

Which vendor do you need?

[justdream]

Huawei please...

Dears,

Pls lookup attached file about Paging over load rate from Radio side.

You can also use another counter to monitor paging performance in BSS part.

Dears, I'm confused !! :L

What's the usage of below counters:

A337:Number of Deletions of the Paging for CS Services on the PCH
A338:Number of Expiries of the Paging for CS Services on the PCH
A351:Number of Discarded Re-paging Messages for CS Services
-----------------

and is it normal to have big difference of Delivered Paging Message to cells in Same LAC?
-----------------

What does it mean when Average of RL3188:OVERLOAD rate of paging (%) for a specific cell = 0.2%
while number od Discarded Paging messages is 15618 !

What's the usage of below counters:

A337:Number of Deletions of the Paging for CS Services on the PCH. --> number of paging messeage is deleted due to over paging's buffer size
A338:Number of Expiries of the Paging for CS Services on the PCH -->number of paging messeage is deleted due to expire time stay on paging's buffer
A351:Number of Discarded Re-paging Messages for CS Services --> same meaning with the first counter but for re-paging
-----------------

and is it normal to have big difference of Delivered Paging Message to cells in Same LAC? yes, its normal. Because, paging channel has lower priority than AGCCH. In cell has high load, you can see more paging discard in high loaded cell compare with low loaded cell

--> it tells you how many paging messeage is discarded and percentige in that cell.
It'll effect to Paging KPI if you have many cell have overload paging channel

I mean how come RL3188:OVERLOAD rate of paging only 0.2% while number of discarded messages is huge

See below example


and which parameter could I change to minimize this big number of discarded message for this cell

It's normal, because paging message sent to each BTS coming from all cells in a LAC. And as me said before Paging channel has lower priority than AGCCH channel. In some cells have very high load, with many calls attempt initial in that cell can cause almost paging message is discarded



and which parameter could I change to minimize this big number of discarded message for this cell

--> try to reduce BS_PA_MFRMS, it'll have you a a lot 37996

Please give some reputation if my infor is useful ;)

I found it set to 1
is it possible to be Zero?
and what could be the impact if its equal to Zero as I found it in previous project was equal to Zero for some cells

Actually, BS_PA_MFRMS, number of multi-frames in a cycle on a paging sub-channel, whose value range is 2 to 9 --> Minimum value is 2, you cant set lower. Lower BS_PA_MFRMS will get more paging capacity but UE spend more power in Idle mode (actually, it's not much).
If you have a alot paging discard you should analysis Paging performance. If PSR decreses so much you need re-plan LAC (to get smaller LAC).

You are right my Friend,
Sorry I got confused, I was speaking about CCCH Blocks Reserved for AGCH That I foud it Zero for some cells

[arturcm]

I completely agree.
