This blog is by Teemu Mäkinen from the Nokia Siemens Networks VoLTE team.
Global Voice over LTE (VoLTE) expert Jukka Hongisto has been on the road sharing his expertise and the latest developments in VoLTE with operators in Japan.
“Japanese operators are interested in hearing more about VoLTE. They’re asking about the maturity of VoLTE technology, VoLTE timelines, and progress with VoLTE rollouts.” As the co-author of the book, “Voice over LTE (VoLTE)”, Jukka is an excellent source of information and expertise. Nokia Siemens Networks has been recognized inJapan as a technology leader and the complete VoLTE solution has been explained and demonstrated to all the Japanese operators.
Besides explaining how and when to best implement voice in LTE networks, Jukka has shared valuable know-how and experience from the industry, including market size estimations and the latest developments in rich communication services (RCS), video and other multimedia services. In line with Nokia Siemens Networks’ overall approach, he shares the underlying business rationale for VoLTE rather than focusing solely on the technology.
All the Japanese operators have already launched their LTE networks, and in every case, they have implemented a Circuit Switch Fall-Back (CSFB) based voice solution. Moving forward, there is now strong interest in VoLTE to provide high-quality LTE voice service, and VoLTE implementations and trials running in several networks. Depending on their existing technology, LTE coverage and the competitive situation, operators inJapanand elsewhere have different timelines for implementing VoLTE. At the same time the industry is improving the VoLTE solution by making some necessary updates to the specifications. The future is sure to bring future advances, and Jukka will be at the forefront sharing them with our customers.
