i am new to huawei system and i worked on eric system.so can u help me to find parameters in huawei for voice like
half rate to full rate parameter,
full rate to half rate parameter,
intra cell handover parameter,
and in gprs
ondemand pdch parameter,
in uplink 4 timeslot
plz help…….6th July 2010 at 07:30 #63392BijoyGuest
half rate to full rate parameter-Ratio of TCHH(%)
full rate to half rate parameter-TCH Traffic Busy Threshold(%)
intra cell handover parameter-Intracell HO allowed
cls parameter-Load HO Allowed
ondemand pdch parameter-Maximum Ratio Threshold of PDCHs in a Cell(%)
spdch-Huawei doesn’t have SPDCH concept.
dynamic allocation-PDCH reforming
uplink 4 timeslot-Allocate Two Timeslots Switch for MS over Uplink.Till C12 version huwai supprts only 2 TSL in UL.

Bijoy is back ! The forum is on fire this morning 🙂6th July 2010 at 09:19 #63394sureshGuest
thanks buddy great thanks a lot.
still want to know abt some parameter
here pdch reforming is for PS to CS.
but which parameter is for CS to PS. IF THERE IS PLZ TELL. because if i am defining dynamic pdch and there is more cs traffic then it will preempt my edge pdch.
So plz tell this also if possible plz tell which are there counters.6th July 2010 at 09:42 #63395BijoyGuest
Check out these parameters
1.Level of Preempting Dynamic Channel
2.Reservation Threshold of Dynamic Channel Conversion
For counters,check R93* counters
Thanks Pix.Hope you will arrange some water:-)(kidding dear)

can we do half rate to full rate and full rate to half rate with quality threshhold like eric.6th July 2010 at 09:48 #63397BijoyGuest
Sure ,there is.
1.IntraCell AMR TCHH-TCHF Qual Ho Allowed
2.IntraCell AMR TCHH-TCHF Ho Qual. Threshold
3.IntraCell AMR TCHF-TCHH Ho Qual. Threshold
4.IntraCell AMR TCHF-TCHH Qual Ho Allowed
& there are also criteria like Pathloss,ATCB etc

thanks buddy here i am facing the problem of poor ho sucess at bsc boundries within same msc everywhere in my network so by enabling handover power boost will help to improve ho sucess?
and one more thing buddy in eric for gprs harware side we are checking gddm capacity how many rps? so for huawei how to check and whats its capacity?13th July 2010 at 06:55 #63399BijoyGuest
HPB will definitely supress the poor radio environment.Also try increasing the Timers T3107 & T3121.
Like RPP in Er\\,in huawei we have GDPUP(PCU).
Max PDCH(static+dynamic) per PCU =1024.
Max cells per PCU =2048
Max PDCH per BSC=8192.
Max PCU Num=32.

Buddy by hopwrboost u are telling my ho sucess improve at bsc boundries ok? BUt will it affect my tch drop because interference will increase ?
And buddy u are telling 32 pcu ?is it per bsc ?i mean like eric in one gddm we can put max 7 rpp and if its 100% utilized then i have to put another gddm.and in eric,nokia only one pcu in bsc so herein huawei can u plz explain?13th July 2010 at 19:20 #63401optimizerGuest
What software r u using for monitoring Um and Abis interface. How can i detect in huawei that bts internal alarms r not active(lets supose huawei want to hide them).14th July 2010 at 05:18 #63402BijoyGuest
HPB will not impact TCH Drop.
Rgarding PCU,this is what I know for BSC6000.
Regarding Nokia,max no. of logical PCU for BSCi was 8+1,higher versions have much more,say the latest flexi BSC have 60+10 logical PCU.

THANKS BUDDY I HAVE STILL ONE CONFUSION WITHOUT HO POWER BOOST HOW MUCH POWER IS RADIATED BY BTS? I THINK IT IS MAXIMUM OR SOMEWHAT LESS?14th July 2010 at 10:34 #63404BijoyGuest
With HPB, the BTS transmit power is adjusted to the maximum before the BSC sends a handover command to the MS. In addition, the BTS transmit power is not adjusted during the handover to ensure the success of the handover.
When the receive level of an MS drops rapidly, a handover occurs. In this case, the BSC cannot adjust the transmit power of the MS and BTS in time. The MS may fail to receive the handover command, thus leading to the call drop.

Hi buddy ,
Thanks for reply but check my question i want to know without ho power boost how much power will be radiated by bts ? is it max or less?
and power control will come in picture?
