StarHub First in Southeast Asia to Successfully Dial GSM VoLTE Calls

By Michael Guta SIP Trunking Report Contributing Writer

As the number of smart mobile devices continues to increase, networks are facing the pressure of handling all that data and delivering it to its customers without any glitches. Legacy networks, or more specifically 2G/3G mobile gateways, were not designed to handle the demands of these new devices. With the rollout of 4G LTE, network service providers will be able to handle the onslaught of traffic demands while at the same time offering more services with greater reliability and security. StarHub, Singapore's fully-integrated info-communications company has become the first country in Southeast Asia to successfully dial GSM Voice over Long Term Evolution (VoLTE) calls.

Compared to standard voice calls, VoLTE allows more speech information to be transmitted with a wider frequency range and more than twice the bandwidth compared to regular voice calls. This creates a conversation that is much more clear and natural-sounding with low background noise.

The company has promised to give its customers clearer calls using its live 4G network in Singapore with services starting next year along with HD Voice service using VoLTE. Although the customer base is low at the moment, the company says this will pick up as manufacturers continue to increase the number of smart phones that are able to support this technology.

To ensure the devices and networks are interoperable, the company has deployed an end-to-end all-IP VoLTE solution from Nokia Solutions and Networks (NSN), and adopted the GSM Association’s (GSMA) standard for delivering telecom-grade voice and messaging services over 4G GSMA VoLTE IR.92 specification based on international 3GPP standards.

"Crossing this major VoLTE milestone marks a great leap forward for StarHub. With VoLTE and HD Voice on StarHub’s 4G and 3G networks, our customers can enjoy supreme crystal clear voice quality when talking to their loved ones anytime, anywhere. Today, we are thrilled to demonstrate our ability to enable richer, future-ready communication services for our customers that can bring them closer to their family and friends through StarHub’s innovations," said Chan Kin Hung, head of personal solutions at StarHub.

The VoLTE market is growing around the world with forecasts of more than eight million customers by the end of 2013. Most of these customers will be coming from the Asia-Pacific region as South Korea and Japan continue to lead the way in full rollouts of the 4G LTE networks. The vast majority of the LTE business is controlled by the U.S., South Korea and Japan respectively, accounting for 87 percent of the market.
