Subset093 EoG Packet Switched performance measurements
Clear CinCom has received an order from the Dutch GSM-R railway operator ProRail to deliver support in collecting EoG (ETCS over [E]GPRS) packet switched performance data with the objective to verify the KPI targets as specified in the draft Subset093 document. The measurements will be conducted in accordance with the draft O-2475 packet switched specification in a GSM-R network supporting both GPRS and EDGE.
For this assignment Clear CinCom has developed a bespoke RF QoS measurement application consisting of a mobile client for the train born side and a fixed server as a land-side unit. The two entities are in condition to measure the following packet switched KPIs as detailed in the draft Subset093 and O-2475 specifications: PS mode service setup (PS-SS), Network Registration Delay (NRD), Attach Delay (GPRS-AD), PDP Context Activation Delay (PDP-CAD), Transaction Transfer Delay (TTD) and ETCS DNS Look-up Delay (ETCS-DLD).
