QoE Assurance: You Can't Control What You Can't See

Posted by Mae Kowalke on Wednesday, February 17, 2016 with No comments
It's no longer enough to have some areas or layers of the mobile network instrumented for performance assurance; with the growing complexity introduced by voice over LTE (VoLTE) and 5G services, operators need granular, end-to-end, real-time visibility across all parts of the network. That's the conclusion drawn by Viavi Solutions in a recent RCRWireless News article

We agree.

As networks virtualize and become more distributed and dynamic, operators must be able to react instantly to maintain Quality of Experience (QoE); visibility and control (increasingly through automation) are both required, and operators are already embracing this paradigm.

For example, to leverage the VoLTE opportunity, operators must deliver assured, end-to-end network QoS to support their services: from user equipment all the way to external TDM gateways. That requires, among other things, complete end-to-end visibility into the whole network (core, backhaul and RAN), and granular control of service quality and the ability to verify actual user experience. Using a combination of active and passive test, with distributed packet brokering (now possible with Accedian's FlowBROKER solution, being demoed at Mobile World Congress 2016 ), this can practically be achieved.

Viavi noted several technologies and trends taking performance monitoring to the next level:

  • Network functions virtualization (NFV)
  • VoLTE and Wi-Fi
  • Self-organizing networks (SONs)
  • 5G
These are topics Accedian has been talking about and focusing on for quite some time, and they all point back to the need for a fully instrumented network that gives the operator actionable insights into performance and its impact on the customer experience. You can't control what you can't see.
