Live VoLTE Call Troubleshooting

  • 19 mars 2014

Tommi Tallgren

Senior Product Line Manager

Mr. Tallgren joined EXFO in 2001. He has more than 10 years of experience in the telecommunications industry, with expertise ranging from support engineering to technical sales, to product management for the EXFO Analyzer product line, including product roadmaps, marketing and sales support. Last year, his focus shifted to live LTE network analysis and troubleshooting, working closely with leading LTE MNOs around the world.  

Mr. Tallgren obtained a Bachelor’s Degree in Telecom Technologies as well as a Master’s of Technology from the University of Oulu. He also completed his military service in the Finnish Air Force Telecommunications Group.

Wireless End to End: IMS/ LTE Networks (VOLTE, VOIP, femtocells, big data)

Successful VoLTE service turn-up is dependent upon comprehensive testing in the live network. VoLTE is an emerging technology that has been plagued by numerous issues related to the implementation of voice codecs, interoperability of mobile devices and the network, voice stream and voice quality, among others.

Join us for this short webcast that presents detailed technical examples of VoLTE troubleshooting cases, and explores ways to capture that data. You will also learn what information you will need to look for when doing VoLTE call verifications.

This webinar will address the following topics:

  • Brief VoLTE signaling overview
  • Methods for faster mean time to repair (MTTR) in response to issues with VoLTE service updates
  • Examples of end-to-end VoLTE call setup with control-plane and user plane troubleshooting needs
