Singapore telco StarHub has successfully completed the first Voice over LTE (VoLTE) call based on the IR.92, the global 3GPP VoLTE standards, in a live network in Southeast Asia.
Customers will "soon be able to enjoy clear voice calls in HD over StarHub's 4G and 3G network anytime, anywhere," said Chan Kin Hung, head of personal solutions at StarHub.
To enable VoLTE, StarHub implemented Nokia Solutions and Networks' (NSN) end-to-end solutions for providing voice call services over LTE. The solutions deployed include 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.
By leveraging NSN's Global services, which provide planning and optimization services from the architecture and design stage to multi-vendor integration and core network migration, StarHub is able to launch VoLTE commercially in its network in 2014.
