    Ovum has conducted extensive research, which included an industry survey with mobile operators and MVNOs around their plans and expectations on VoLTE and ViLTE. There were a total of 108 respondents to the survey, representing operators from around the world. Asia Pacific was particularly a strong region in terms of operator responses, because of the early success of VoLTE there. In this whitepaper, Ovum presents its survey findings on VoLTE market opportunity for operators and also highlights the inherent challenges operators will face as they migrate towards VoLTE.

    Market statusOver the last few years, LTE deployments have accelerated

    worldwide as operators look to increase network capacity and offer higher-speed data services to their customers. LTE is the most rapidly deployed wireless technology today with 313 live LTE networks

    worldwide at the end of 2014. According to Ovums research, there were another 143 LTE networks planned, in deployment, or in a pre-commercial phase at the end of 2014.

    Executive summaryIn briefOperators are increasingly looking towards new services to drive mobile revenue growth. Voice will continue to remain relevant, but voice services, evolved into a broader context to include multimedia features, are expected to gain momentum and enable operators to compete against the growing burden of OTT voice services. We already see Voice over LTE (VoLTE) services gaining fast traction, with a slew of operators announcing VoLTE launches or trialing VoLTE for their domestic markets. It will be equally important for operators to expand VoLTE services across borders, in order to extend the same good quality of experience to their travelling customers. Many operators are likely to implement international VoLTE within next 6-12 months.

    1. Operators need to develop new voice opportunities and VoLTE will be a crucial step forward, in order to offer an improved end-user experience. VoLTE, combined with rich communications suite (RCS), has the potential to bring new opportunities for operators and to gain innovation leadership. This will be crucial to compete with the OTT players and other network providers. In addition, VoLTE will bring spectrum efficiencies and opex savings for operators through network consolidation.

    2. The VoLTE ecosystem is getting there, with more than 80 operators in different stages of VoLTE deployment and many others trialing the technology worldwide. Asia Pacific is one of the leading regions for VoLTE deployment with operators in South Korea, Japan and Hong Kong having launched commercial VoLTE services. Operators in the US are a close second with commercial VoLTE services already deployed across many markets.

    3. As operators launch VoLTE services across their domestic markets, they will soon need to start thinking about international VoLTE interconnection and roaming for international service continuity. International VoLTE could be a significant opportunity for operators to gain the first-mover advantage; however, there remain the inherent challenges of interworking and interoperability. Some of the recent trials showcasing cross-border VoLTE implementations, such as China Mobile and KPN Mobile demonstrating IMS-based VoLTE roaming supported by iBasis IPX, pave the way for VoLTE interoperability and commercial roaming deployments.

    4. For VoLTE roaming, operators will need to remain flexible between home routing and local routing solutions. Local routing can be a powerful solution for operators to offer an improved quality of service to roaming customers by serving them through local operators. As local routing means that the VoLTE voice and Video over LTE (ViLTE) calls will not need to trombone back to the home network, it will offer a better quality of experience at a reduced cost.

    This rapid pace of LTE deployments is driving an increasing number of LTE connections worldwide. According to Ovum research, there were 386 million LTE connections in total at the end of 2014, and this
