StarHub has successfully completed the first Voice over LTE (VoLTE) call based on IR.92 in a live network in Southeast Asia. The operator implemented Nokia Solutions and Networks’ comprehensive end-to-end approach for providing voice call services over LTE.

“Together with our key technology partner NSN, we are committed to continually enabling innovative future-ready technologies and services to benefit StarHub’s customers,” said Chan Kin Hung, head of personal solutions at StarHub. “StarHub’s landmark VoLTE achievement today reaffirms our commitment towards delivering an unparalleled user experience to our subscribers, who will soon enjoy crystal clear voice calls in HD over StarHub’s 4G and 3G network anytime, anywhere.”

To enable VoLTE, StarHub deployed NSN’s Open TAS (Telecommunications Application Server) for voice, Home Subscriber Server (HSS) and IP Multi Media Subsystem (IMS). VoLTE services are part of an existing LTE agreement that was signed between NSN and StarHub in 2012. NSN had supplied its Single RAN (Single Radio Access Network) platform based on its compact and energy-efficient Flexi Multiradio 10 Base Stations to enable StarHub to run GSM and LTE concurrently on the 1800 MHz band.

NSN’s Global Services provide planning and optimization services, from the architecture and design stage to multi-vendor integration and core network migration, and has helped put the operator in a position to launch VoLTE commercially in its network. It also provides Implementation and Care services.

“By enabling the first 3GPP standard VoLTE call in Southeast Asia, NSN has helped StarHub reach an important milestone in the region’s telecommunications industry, an achievement that lays the foundation for the delivery of HD voice services over LTE to users in Singapore,” said John Lancaster-Lennox, head of South Asia at NSN. “This is yet another strong proof-point that NSN remains committed to supporting StarHub in its endeavors to build a cutting-edge network infrastructure in the country.”

NSN has 97 commercial references for LTE and has deployed its IMS in the world’s largest live LTE network. More in Current Development of the Global LTE Subscriber Market, 4Q 2013.
