LTE: from Tests to Implementation.” LTE Networks and Traditional Mobile Services Mobile communications networks based on the LTE standard, developed by the 3GPP Consortium for high-speed data communication, are at the stage of active global deployment. According to GSA, from December, 2009, when the first commercial LTE network was launched, to the middle of March, 2013, the amount of commercial LTE networks in 67 countries reached 156 and 412 operators in 125 countries invested in the technology. It is forecasted that 244 commercial LTE networks will be deployed in 87 countries by the end of 2013. The LTE ecosystem evolves rapidly. It is anticipated that by the end of 2013, some 300 various models of LTE-compatible terminal devices will be available on the market. According to GSMA’s forecast, the number of LTE-compatible smartphones in use will grow to 920 million by 2017, up from 62 million as of the end of 2012. At the same time, there is a significant amount of smartphones on the today’s market that can operate only on 2G and 3G networks; their quantity is estimated 1.9 billion by the end of 2013. A critical issue for the spread of LTE is the support of traditional services, namely telephony and SMS, which still bring most of mobile operators’ revenues. LTE networks belong to All-IP-class (“all over IP”) networks, utilizing the principle of packet switching on every section of the network. For this reason, the LTE technology is not meant for supporting “voice” and SMS the way it is realized on switched 2G and 3G networks. Thus, the implementation of VoLTE (Voice over Long Term Evolution), a communication of voice over an LTE network, is one of the most urgent tasks for mobile operators implementing the 4G technology on their networks. In 2013, the revenues from voice services will amount, according to GSMA, over 60% of operators’ revenues; therefore, providing the support of voice services on LTE networks becomes a topical problem. However, the implementation of VoLTE will be not so quick, as against the growth rates of commercial LTE networks.

As its basis, the IMS (IP Multimedia Subsystem) specifications by 3GPP Consortium were used. Operators hope that VoLTE will ensure the provision of voice services over a packet switching network characterized by a carrier-class quality, as opposed to VoIP services by third-party providers (so called OTT providers). On networks with VoLTE support, the subscribers may use, for example, such services as HD Voice and Rich Communication Services (RCS). As of March, 2013, from 156 LTE networks operating worldwide, the support of VoLTE was implemented for only three of them – MetroPCS (the USA), SKT and LG U Plus (South Korea). Several other U.S. operators are planning to implement the technology by the end of 2013 – the beginning of 2014. Table 1.

To implement this technology, an operator should deploy IMS and build a LTE radio access network on its core network. Interim technologies on the way to VoLTE are CSFB, SRVCC and SVLTE. In the medium term, the main drivers of implementing VoLTE in Russia will be the following: spread of smartphones featuring LTE support, widening of the 4G coverage and increasing pressure from OTT services. The typical strategy of an operator for implementing voice services on LTE networks involves implementing an “interim” CSFB technology with a gradual transition to IMS and VoIP. Until the national LTE coverage is ensured, the SR-VCC (Single Radio Call

When a subscriber leaves the VoIP coverage area, SR-VCC provides transition from IMS based VoIP to circuit-switched (CS) voice and vice versa. The final stage is the implementation of a full-fledged IMS platform and transition of all calls to packet networks (IMS based VoIP). VoLTE-Compatible Devices As of March, 2013, less than 10 models of subscriber devices compatible with this technology are used in the countries which implemented VoLTE in August, 2012 (the USA and South Korea). It is expected that, as VoLTE spreads, the model range will be considerably expanded. Table 2.

This is one of the main constraints for this technology development, and it will be overcome in the medium term. Forecasts and Prospects According to ARChart, the VoLTE market will experience a significant growth in the coming years. About 2 million devices with VoLTE support are expected to be sold in 2013 (mainly, in the USA and South Korea), the revenues from VoLTE services reaching approximately $56 million. It is forecasted that the number of VoLTE users will amount 70 million by the end of 2016 (about 10% of LTE users). According to Infonetics Research, by 2016, the share of VoLTE on the VoIP service market will be 14%, which means that the lion’s share of VoIP will remain under the control of OTT. The Signals and Systems Telecom Company predicts LTE equipment industry’s growth with the compound annual growth rate (CAGR) being approximately 150% in 2013 – 2016. Analysts claim that the number of OTT and VoLTE services users will increase several times by 2016, but nonetheless, the number of 2G and 3G networks subscribers will predominate as before. In the medium term, the VoLTE market will remain a niche one, accounting for 1/7th of the revenues on the VoIP market. View slide
