KT announced a new test of 5G multi-radio, low latency technology on its commercial network with Tessares. Named ATSSS (Access Traffic Steering, Switch and Splitting) by 3GPP, the techqniue is based on the multi-path TCP platform used by Tessares to offer hybrid internet access platforms. KT hopes to use it to offer low-latency 5G services integrated with LTE and Wi-Fi access.
ATSS is part of the 3GPP Release-16 5G System Architecture Standard (3GPP TS 23.501) and was defined in collaboration with KT, Apple, Deutsche Telekom, Orange and Cisco. ATSSS technology reduces the initial session setup time to achieve 5G ultra-low latency in a multi-radio context, resulting in a setup delay of less than half the time compared to previous approaches. KT and Tessares have together led the international standardization of this initial delay reduction technique through the IETF TCP Working Group.
Tessares is a Belgian company providing software-based hybrid internet access bonding to telecom operators such as Proximus and KPN. They have used the software to develop hybrid LTE-DSL broadband services.
At the recent IETF meeting in Montreal, the test results from KT’s 5G commercial network were announced. Other working group members gave positive responses on the effectiveness of the technique, Tessares said. Leveraging 5G low latency multi-radio access technology can provide customers with faster and more reliable networks. In addition, low-latency network technology is applied to KT’s enterprise dedicated 5G service, which is expected to greatly contribute to the activation of delay-sensitive enterprise applications such as smart office, smart factory, etc.
The success of this low latency multi-radio access technology test will allow customers to take advantage of existing LTE and Wi-Fi networks, as well as 5G, to enable wireless services at higher speed and quality, said KT.
