Hello All
this is to start the discussion over the performance issues in GPRS/GSM network.
can anyone suggest what issues are created when a GPRS is newly integrated in the GSM network, specially in Air interface.Hi
I read your probelm ,in a newly
integrated gsm network the first which we face is there how much timeslot is given for the GPRS,and how much you given following specify
1-CDEF
2-CDED
3-TRP
4-BFG
5-NSEIis that correct format or not
and the timeslot or dedicated or dynamic
Regards
rajendera rautelaNeed to include the following essential BSS parameters as well:-
1. RAC
2. GENA
3. GTRXDear All can you explain all these TERMS CDEF, CDED etc
Hi Amir
CDED STANDS FOR DEDICATED GPRS CAPACITY
CDEF DEFAULT GPRS CAPACITY
CDED MUST BE SMALLER THAN CDEFGIVE ME YOUR MAIL ID I HAVE A SLIDE WHICH WILL GIVE YOU A CLEAR PICTURE ABOUT THIS
STAY IN TOUCH
HI,
Can u tell me why cdec is les than cdef? cdec means dedicated slot and cdef means flexible?
CDED is % of total tsl always used for data and CDEF is % of total tsl that can be dynamically allocated for data but will revert to vioce if needed. A simple example :
Total tsl avail – 10
CDED 20% = 2 tsl dedicated to data.
CDEF 40% = 4 tsl that can be used for data unless need for voice.
CMAX 100% – I think this is combo of CDED and CDEF = 60% = 6 tsl in this example.
So CDED cannot be greater then CDEF since you would not be using any tsl dynamically then and have no need for it.
This is my best understanding of these parameters. If it is wrong in any way please post a detailed explaination.ok thank u can u tell me something abt ms power contro and bts power control?
can anyone please tell how can i change cded cdef if my cell has high blocking what values will be appropriate for GSM and DCS. And what impact it will show . Kindly reply
how do we know which settings to give for CDED and CDEF?
