VoLTE Customer Experience – Breaking down the Barriers

Quality of Experience

To date, it appears most of the MSPs that have deployed VoLTE have relied on active testing to effectively “spot check” the end-to-end service improvements and overall performance. Very little appears to have been done to look at overall QoE across the entire customer base.

Gaining an Insight into VoLTE Customer Experience via Analytics

VoLTE Customer Experience

Service providers are demanding more from their customer experience and service assurance solutions because they have a keen awareness of the richness and value of the information that flows across their networks. Reliably and accurately extracted, this information can be used to help manage not just the network, but also the services offered and the devices deployed. Insights can be also be gained around the performance of providers’ vendors and—most significantly—the experiences and value of their customers.

Test Failure

In one recent test Empirix was involved with, callers were complaining about long connection times and poor voice quality during a storm. The company involved conducted a test of its SBC to better understand the origin of the issue. During the test process, the organization discovered that, while having a registration flood of 10,000 concurrent SIP registrations, SIP call setup time doubled. Moreover, jitter increased on the SBC.
