2G Data speed low

[radio_network]

2g data speed is low. We have checked all the config but nothing is working. upto MCS 9 we are getting /.But whaterver it may be. mobile is getting allotted only one TS PDTCH. Eqpt:NORTEL
Any suggestion recommendations pl/

You mean that E-GPRS data speed is low ?

[radio_network]

EDGE speed is low

Do you try to increase number of PDCH available ? In ALU system, we have 02 parameters called MIN_PDCH and MAX_PDCH
If 2G voice traffic is high, I think you should increase more TRX and then increase more Min, Max_PDCH
Using tool to collect TBF assignment and data traffic in Busy hour for more details

In my case even if MIN PDTCH is 3, only one TS is getting allotted. We are trying to find the reason. Could not find any solution.

suposse aBis is ok. availability & dimmension. cs traffic has priority so beware of number of timeslots

It's so strange. Pls check again the Max_PDCH ( higher than Min ).
CS traffic ? TBF Assigment in busy hour ?
Check again Abis capacity for site ? And does it happens with whole network or only 01 site ?

It's so strange, how about max-pdch ? CS traffic is too high ? and Abis capacity for site ?
Does it happen in whole network or bsc , site ?

Thanks for the reply.
This is for whole network, Even with 2 Abis per site.
Window size is always same.
Is there anything at PCUSN or SGSN . could not solve this problem.
we are having 4 AGPRS between BSC and PCU.

Mean that you only have 4 E1 for GPRS / 01 BSC ?
Pls increase more for GPRS , base on TBF assignment in busy hour , at leas in busy hour , 80% capacity of GPRS is max using
