USA -iBasis (www.ibasis.net), a KPN company, and SK Telink (www.sktelink.com), a subsidiary of South Korean mobile operator, SK Telecom (www.sktelecom.com) announced the first successful commercial interconnection for international live VoLTE services over their multiservice IPX networks.
Both mobile operators are leveraging real time sensitive interconnect services in order to deliver HD (high-definition), low-latency, crystal-clear voice services internationally to their 4G/LTE consumers. iBasis and SK Telink are preparing for a further smooth commercial rollout of VoLTE interworking to their subscribers in South Korea and the Netherlands respectively.
South Korea was the first country to launch national VoLTE in 2012 while KPN launched its national VoLTE service in 2016. iBasis and SK Telink, parties with proven track records in delivering international IP-based services, are providing the IPX interconnectivity between the mobile networks of KPN and SK Telecom.
The iBasis IPX core network, fully SIP and SIP-IMS enabled, supports multiple interworking functions. Based on GSMA specifications, it supports EF traffic (conversional) class services in order to handle real-time services and ensure end-user service quality.
“There is no room for error when it comes to high quality voice calls,” said Wonyoung Yun, CEO of SK Telink. “After significant testing and development efforts, we are very proud to be able to provide our subscribers with best-in-class quality and service. Like us, KPN and iBasis equally share a strong quality and innovation focus on VoLTE. In our position as pioneer with the ability to lead with new technology, we have leveraged the extensive experience of iBasis in Voice-over-IP, HD Voice and global IP deployments. Our close collaboration will help operators improve speed and efficiency in their international deployment phase and create new value for customers.”
“We are extremely pleased to have joined forces with SK Telink to establish the first international VoLTE interworking connection for South Korea, one of the highest penetrated LTE Mobile countries worldwide and pioneer in VoLTE adoption and innovation,” said Feddo Hazewindus, CEO of iBasis. “The strong engineering and operational collaboration between SK Telink and iBasis teams has managed to solve multiple implementation challenges which are critical for performing and maintaining high quality VoLTE services globally and we are proud to have established this milestone together”.
With more than 100 commercial VoLTE Networks, the march toward international VoLTE commercialization is also moving forward. High-quality voice service encourages usage on the mobile network, deterring users from seeking alternatives. Combined with global availability, they can become key competitive advantages for mobile network operators.
In addition to VoLTE interworking, the iBasis VoLTE solution also supports VoLTE roaming, both local breakout and home routing, and helps operators overcome challenges such as global reach for VoLTE calls, signaling and media interworking between VoLTE and non-VoLTE networks, supporting VoLTE global roaming, exploiting HD Voice and video (ViLTE) capabilities.
