Maximizing Inbound Roamer Revenues by Monitoring Their Application QoE

There are many tricks in this book. Making sure that your signal strength is maximized in airports and other ports of entry is a classic. But once you’re dialed up your signal strength to 100 and put as many radio towers and DAS access points as you can muster, what’s next?

Well, it comes down to quality of experience for the roaming subscribers. The home operators are monitor that experience for their subscribers. They want the best experience for their subscribers.

So how do you monitor your network with a focus on the experience that the roamers are getting?

The answer is Application QoE monitoring from AppLogic Networks.

How this works is the traffic from your inbound roamers hit your RAN, and from there travels over the Gp,S8, or N9 interfaces to one of several IXP points in your country. From there it goes over a connectivity provider, and typically hits a couple of Autonomous Systems (AS:s) representing Internet providers along the path to the home operator, where it’s finally routed to the internet.

If you monitor the Gp,S8, or N9 interfaces at the IXP using software from AppLogic Networks, then we will create Application Based Customer Sentiment records, containing:

• User – MSISDN or similar
• Location – CellID, Node, Region, Home Operator, etc
• AS-Path & Origin AS – The AS-Path for the traffic tunneled back to the home operator
• Application – Netflix, Zoom, Whatsapp, etc
• Content Category – Streaming Video, Video Conferencing, Audio Streaming, Browsing, Messaging, etc
• Device – IMEI based, eg Iphone 15

And for every session and every dimension above, the following KPIs

• Application Score – A MOS score based on subjective testing classifying the experience using the app on a 5 point scale
• Throughput In/Out
• Latency (in your network) and Latency (end to end)
• Loss rates
• Jitter
• Inter Packet Gap
• Etc

With these kinds of measurements, we build reports per cell, per city, per device type, per operator, per app and let you see where you’re not providing a good QoE for the roaming users. What cells in your network would benefit the most from improvements based on roaming user experience for different apps?

You can also see what visiting operators are getting the worst vs best experience.

With the per session data, troubleshooting becomes much easier and grounded in the subscriber experience, not in RAN metrics.

So if the inbound roaming experience and revenues are important to you, you should look into Application QoE monitoring of your roaming traffic.
