Reply To: Uplink TBF & Downlink TBF


Thanks a lot Pix, I’m new in GPRS system. Could you give more information for the following questions:

1. Is there any value for TBF?
2. Why do we use TFI if we already have TBF?
3. Is TFI cell parameter and changeable?
4. If I want to know the downloaded/uploaded traffic in a cell. To which counter should I look at?
5. If I want to know the average DL/UL speed. To which KPI should I look at: RLC throughput or LLC throughput?

Thanks a lot in advance.
