Hi Pix,

Power values are in dB

hi,

so… when i read “MAX power level of MS=5”
it means
MAX power level of MS=5dBm ???

Sorry pix in replying late & confusing you, I went sick…Back now

When we say
MAX power level of MS=5 it means 33dbm & MIN power level of MS=16 it means 11dbm

suzanne,

i’m glad you’re fine now ๐
well, my only concern is that i can’t read the numerical values you’ve written. You must translate them in dB or dBm, please ๐

I understand the translation is not complicated, but i just can’t do it…

thanks ๐

Hey Pix !! Hope you are doing fine..

Well, Let me describe it properly:

Power ref table is as under:

value(0-2)=39dbm
value 3 = 37dbm
value 4 = 35dbm
value 5 = 33dbm
………….
value 16 = 11dbm
value 17 = 9dbm
value 18= 7dbm
value(19-31) = 5dbm.

hi,

I begin to think that you just don’t want to convert your previous post, where you list all your parameters, into understandable units.

Dear Pix, Really very sorry to create such trouble to you…

Here i go with complete description :

1)MAX power level of MS=5
2)MIN power level of MS=16
Parameter 1 & 2 are mapped as Power ref table as under:
value(0-2)=39dbm
value 3 = 37dbm
value 4 = 35dbm
value 5 = 33dbm
………….
value 16 = 11dbm
value 17 = 9dbm
value 18= 7dbm
value(19-31) = 5dbm.

3) MIN power level of BS=10–>(where 0:Pn,1: Pn-2 dB;15:Pn-30 dB & Pn=The maximum power level of BTS is Pn)

4)Increase uplink level=25–> (Ths 0-63 mapped with -110 to-47)dBm i.e 0=-110 & 63= -47dbm.
here 25 = -85dBm.

(Ths 0-63 mapped with -110 to-47)dBm i.e 0=-110 & 63= -47dbm.
here 35 = -75dBm.

Parameter 6&7 are based on band (0to7)
(Ths 0-63 mapped with -110 to-47)dBm i.e 0=-110 & 63= -47dbm.
here 20 = -90dBm.

(Ths 0-63 mapped with -110 to-47)dBm i.e 0=-110 & 63= -47dbm.
here 35 = -75dBm.

Parameter 10&11 are based on band (0to7)
where P/N for all UL/DL is 2/3

Also,Handover MarginRxQual is =6dB

Hi Suzie,

Ok, so you can try the following values (keep everything else like it is)

Min power level of MS=19

that should help reducing the UL Interference. Regarding the DL, your settings are already quite good. You could try this :

But I can’t be sure that it will enhance your network.

Hey Pix…. I am back, How r u doing dear

Min power level of MS=19 i.e 5dBm–> Will it not increase Call drop or degrade voice quality,

Increase & decrease uplink level to 15 & 25, will it not delay the Power control ??

suzane,

I’m kind of useless if i’m starting to give advices on HOW TO increase the call drap rate, and HOW TO degrade voice quality :))

The settings I’m giving you are very standard. They are more aggressive than yours, but it’s only because yours were very conservative.

What are your increase step sizes, and increase factors ?

Regards

Dear Pix,

Please don’t take it on other way… Let me Implement these & will share the Pre-Post

I have activated DTX+AMR on FR and just AMR on HR, and the voice quality is good enough, and statistics so far so good.

If u have a very high problem with Dropped calls Statistics but the voice quality is good, just increase “Radio Link Time Out” to 64.

Danny,

DTX UL or DL ?

Which version of ALU are you using ? B10 Mr7 or B11 ?

Yann

UL and DL (HR)

I work with Huawei, but Its the same, in the past I work with Siemens, and the differences are minimum.

Try to deactivate DTX on HR, In my experience DTX affect HR Voice Quality, and we don’t care to save battery on phones, I rather keep voice quality.

And remember wen u use AMR, its recommending increase Radio Link Time Out to 64, we can save voice quality but the carrier quality its the same.
