Summary Bullets:

  • Deploying a VoLTE-capable network core has become much easier and faster with NFV.
  • However, some of today’s pre-integrated vVoLTE solutions may re-introduce the specter of vendor lock-in.

Like virtual customer premises equipment (vCPE), virtual voice over LTE (vVoLTE) is viewed by operators and vendors alike as one of the top NFV use cases slated for early implementation. In many ways, vVoLTE’s popularity has been the result of fortuitous timing. VoLTE depends on the deployment of the IP Multimedia Subsystem (IMS), which until now has been both a costly and protracted deployment undertaking for the carrier. However, NFV now offers infrastructure cost reduction by using shared common hardware and a faster, software-only implementation of IMS using virtual network functions (VNFs). Put these two together and you seem to have a ‘marriage made in heaven’ (that’s good). Continue reading “Virtual VoLTE: A ‘Marriage Made in Heaven’ or a ‘Double Whammy’?”
