BSNL 3G Network Parameters affecting Data Speed 20-8-2009
Scope This presentation describes the various parameters that impact 3G data speed and the modifications done in these parameters to optimize BSNL 3G network. The following nodes are covered: • Node B • RNC • HLR • SGSN Additionally, the following are also covered • Description of the above parameters • Process to check the data speed • Tools to check data speed
Network Elements affecting Data Speed • Many contributing factors affecting end-user performance Signal strength Interference Cell change Loading Routing, QoS profiles etc Transport errors GGSN NodeB NIB UE RNC SGSN Availability Operating System TCP settings Applications protocols (FTP, ICMP,HTTP, UDP, RSTP etc) Speed measurement method Internet Which site ? Routing, delays, congestion, QoS profiles etc
Data Check Audit Process to identify possible issues, in case desired speed is not achieved: • Check speed through NetPerSec tool • Cross-check HSDPA related parameters in RNC & Node B • Check SGSN Profile • Check HLR Profile (user profile) • Check for Time Delay & Jitter using Ping Plotter tool
