Dear Huawei Experts
There is one parameter in Huawei inner PCU (Maximum Ratio Threshold of PDCHs in a cell)
Its value is in percent (default=30 %)
What does this parameter mean? Is it for static or dynamic data TSs?
Please your advices
Thanks in advance13th May 2010 at 05:25 #62615HW_JUNIORGuest
Dears any comment???13th May 2010 at 10:04 #62616SHELDONGuest
This parameter is used to restrict the percentage of TSs that can be used as PDCHs (both static and dynamic).
Consider a typical 4TRX cell with 1BCCH and 2 SDCCHs. Then:
Total number of TSs that can be used for traffic(voice or data)=4*8 – 3 = 29.
Now, if ur ‘maximum ratio threshold of PDCHs in cell’ is 30 for this cell, then:
Maximum no. of PDCHs = 0.3*29 = 8.7. This means that a maximum of 9 TSs in this cell can be used as PDCHs.
This also means that if you have eg 2 static PDCHs, then you can have a maximum of 7 dynamic PDCHs.

Thanks for information.
As I know for static TS I should add PDTCH to Channel Type. If I don’t have any PDTCH TS in a cell and Maximum Ratio Threshold of PDCHs is 30 %.
What does it mean in this case?
Is there any static TS in 30% if I have not added PDTCH to TRX.

Please your comments, it is very urgent for me.
Thanks for understanding14th May 2010 at 13:17 #62619SHELDONGuest
This threshold applies to the sum of all PDCHs, whether static or dynamic.
If you don’t have any static PDCHs (PDTCH TSs) in a cell, then this threshold will only apply to the dynamic PDCHs. That is, a maximum of 30% of TCHs in that cell can be used as dynamic PDCHs.

Thanks a lot 🙂19th May 2010 at 16:09 #62621nitinGuest
can anybody explain me ????
how can i improve EDAP congestion24th June 2010 at 16:51 #62622VinayGuest
Hello Mr HW_Junior.
In Huawei Maximum Ratio Threshold of PDTCH in a cells we go for only 30%. And we can use this because user can use multi-slot channel when they use the data.
If we go for 30 then it comes around 1.8 that is equal to 1, so if you want to use multi-slot then go for more than 30%. And for maximum conversion we are using different parameter in Huawei.22nd September 2010 at 04:14 #62623Md.Mamunul islamGuest
Whats the activity of this parameter? can anyone answer..
Uplink Multiplex Threshold of Dynamic Channel Conversion26th September 2010 at 11:49 #62624newoneGuest
if my mobile supports 4 timeslot in downlink and in my cell 4 pdch and if i surfing small application then every time i will get 4 pdch or its depends on application?
is there table in bsc i mean multislot class mobile list?18th January 2011 at 22:06 #62625OmerGuest
Sheldon is right. You can change the threshold if you want more .20th January 2011 at 16:00 #62626krishGuest
according to ur example if i have 9 pdch ( which includes 2 static) then on abis level how to define ?
is it is 16 kbps or 64 kbps?
can u plz help how to define pdch on abis whether its static or dynamic?29th January 2011 at 17:50 #62627krishGuest
