I am getting difference (Delta) in data download at Cell Level – Bytes of LLC Frame Downlink data TBF including GPRS & EGPRS (cumulative of all cells in the network) and at GGSN level (Bytes of GTPv1 data packets received from Gn/Gp(byte)). This difference is about 30GB.
Please help me to know the possible reason for it.
is there any mechanism by which we can determine throughput per user @either RLC or LLC level especially in siemens. Also which throughput (/tbf or /tsl) is more reflective of the actual throughput the user is getting?
even i m getting huge difference in GPRS/EDGE download (KB) around 100GB difference at radio & SGSN end.
i understand there will be some difference as these two are measured at different layers and using different counters.
can anyone explain why there is difference in data download at both end and how much difference is acceptable.
