3Welcome to the first ROCCO Research Survey specifically on VoLTE Roaming. The survey is for all MNOs whether or not they have VoLTE today or not. The purpose of this Survey is to understand the current vision of MNO’s in terms of meeting the demands of the VoLTE service in Roaming and Interconnect scenarios.

Take the survey

All MNOs who take part will receive a special Executive Summary of the reports findings with key strategic information. The research is hosted and conducted by ROCCO.

VoLTE is on just about every MNOs minds these days. Our LTE Roaming Strategy Report 2015 told us that LTE was going to be big despite the challenges with roll-out, compatibility of Roaming Partners and IPX maturity. VoLTE was a major concern for MNOs within that report and in our IPX Networks Vendor Performance Report 2015 MNOs also indicated that when it comes to VoLTE there were still a lot of open questions.

As the market matures but still lacks a common direction, ROCCO has been interviewing MNOs who face these challenges and with their specific help has designed two new research studies which focus on extracting useful and important strategic information on where MNOs intend to go and how. This Research for MNOs will be followed tomorrow by research for IPX Vendors on VoLTE Roaming and Interconnect. Culminating in a single Market Intelligence Report.

The survey will take 8-10 minutes to complete. Mandatory questions are marked with an asterisk*.

Background on VoLTE:

The LTE standard only supports packet switching with its all-IP network. Voice calls in GSM, UMTS and CDMA2000 are circuit switched so with the adoption of LTE, carriers need to re-engineer their voice call network. VoLTE (Voice Over LTE) follows an approach that is based on the IP Multimedia Subsystem (IMS) with specific controls for voice service on LTE.

This approach results in a voice service being delivered as data flows within the LTE Data and no dependency on CS voice needs to be maintained. Voice over Long Term Evolution (VoLTE), which is the next generation technology, will soon cause a major disruption for roaming services currently being delivered by core telecommunications operators, as more operators rollout the VoLTE service.

One of the challenges with VoLTE calls is dealing with what happens to the call when a user leaves an LTE coverage area, which are still limited in scope compared to legacy networks. Voice is cited by customers as the second most-common reason for churning from a carrier.

Thank you for participating.
