  • Review presentation against presentation techniques notes and prepare presenter cards
  • Emerging markets.
  • Better usage
    Least cost routing
    Fewer customer complaints; carriers offering QoS incure fewer complaints from customers
    Quality E2E results in less effort and costs spent on troubleshooting and fixing
    Too much focus on cost often leads to poorer service and imapcts profits
    Which trouble tickets are relating to poor quality?
    Call termination rates is a strong indicator of poor quality.
    E.g. is it acceptable for customers to make 4-5 attempts to get acceptable line quality? Impact on depends on customer volume and destination.
    Normally have control of outbound roaming traffic that is passed to own carriers.
    Important to also monitor incoming roaming traffic that is terminated in unusual ways e.g. SIM boxes (see slide 2). IN02 describes impact of SIM boxes on QoS.
    By removing SIM box traffic an operator in South America made $20m improvement in 6 months.

    SIGTRAN is SS7 over IP; CAMEL is feature of SS7.
    GSMA RILTE project looking at roaming QoS for 4G/LTE (J. Boggis).
  • GRQ can help close the gap between roaming operations and finance function.
  • Payback =< 12 months.
    ROI?
  • E2E collaboration
  • What to change?
    QoS is an enabler for new propositions; offers market differentiation; mirror tools and knowledge into NOC (already 24/7).
