This year’s LTE Voice Summit, held with host partner 3UK, had a pragmatic theme, with many more operators presenting on the extreme challenges they had faced with VoLTE deployment. And, it was not only noticeable at the conference – Deloitte claims 100% increase in VoLTE deployments in 2016. The fact is, VoLTE is really taking off. There have now been commercial VoLTE deployments worldwide, including April 2016 in Turkey, where we are proud to claim TEMS’ achievement in delivering Turkey’s first VoLTE benchmark deployments.
While we have discussed how to avoid service disruption in general, there will be times when issues arise. When they do, it’s essential to ensure that they are resolved as quickly as possible, so that any resulting disruption is minimized. “Mean-time-to-repair” (MTTR) is thus a key metric and reducing this is a key strategic imperative. To do so, an optimized service assurance platform and processes are essential. In the last of this series of articles, we explore how this can be achieved and the necessary requirements that should be in place.
Active monitoring generates traffic based on the use of standardized tests. Such tests allow a picture to be created of the experience of services that customers actually experience in the network when they use their devices. They take advantage of the complete data set available from the network (including signaling collected by passive probes, CDRs and element logs), and allow the diagnosis of faults and the analysis of unexpected negative performance trends.
Operators have a number of requirements to help ensure the smooth operation of their networks. These include access to end-to-end visibility of service performance and the underlying network that supports it, and also the ability to correlate between service impacts and resulting network failures. Without this knowledge, troubleshooting will be too slow and too reactive to avoid more failures. In turn, this will lead to growing disappointment for customers (and managers) in the new revenue generating services, such as on-demand networks that are just beginning to emerge.
At this year’s 5G Asia, September 26-28, Ascom Network Testing’s Technical Sales Manager, Muhannad Al-Abweh, will be discussing the importance of testing mobile video services. As Muhannad prepares for his travels to Singapore, we thought we’d go ahead and help set the stage for his presentation. But this is no excuse for you to not plan on attending the panel discussion he will participate in on September 27th, titled Mobile Video Services on the Path to 5G at 12:45.
