"MNOs' investments in 5G IMSs are small compared to those in the 5G RAN, but MNOs risk jeopardising their 5G investments if they do not invest more in IMSs in order to deliver VoLTE and other value-added services."
Only 13% of voice calls worldwide were made using VoLTE in 2019, yet VoLTE is essential for mobile network operators (MNOs) that plan to deploy 5G and shut down their legacy networks to save costs. Vendors have an opportunity to address an USD18.1 billion market (from 2018 to 2025) as MNOs deploy cloud-based IP multimedia subsystem (IMS) networks or migrate existing physical networks.
This report answers the following questions:
- What does a lack of IMSs mean to MNOs and how should vendors help?
- What revenue opportunities will MNOs miss if they do not deploy IMSs?
- Why should MNOs deploy VoLTE services?
- How will VoLTE deliver network efficiencies and allow MNOs to reduce network costs?
- Why has VoLTE not been widely deployed yet? What are the challenges of deploying roaming VoLTE?
- What are the IMS components and how can vendors derive additional revenue as MNOs migrate from physical infrastructure to virtual ones?
MNO's IMS challenges and current deployments and
the opportunities that these provide for vendors
