(Seoul, February 14, 2024) NetCube Inc. (CEO Dong-ho Yoo), in collaboration with the Korea Railroad Research Institute (President Seok-yun Han) and Cybertelbridge, has developed a 'Network Slicing' based Mission Critical Service technology and successfully demonstrated it for the first time in the world on a 5G specialized network testbed.

Mission Critical Services are 3GPP (3rd Generation Partnership Project) standard technologies designed to stably support multi-party voice, video, and data communications, consisting of MCPTT (Mission Critical Push-To-Talk), MCVideo, and MCData.

Network slicing, a core 5G mobile communication technology, is a technique that divides a single physical mobile network into multiple independent virtual networks, simultaneously providing customized communications for various services requiring ultra-low latency like autonomous driving or high-speed video services.

By utilizing the developed technology, 5G networks can differentially provide resources and services according to each service's quality requirements, enabling transmission priority control for MCPTT, MCVideo, and MCData services.

​NetCube, together with the Korea Railroad Research Institute and Cybertelbridge, has developed and successfully demonstrated a technology where 5G terminals can access two or more mission-critical service-specific slices, enhancing security through slice-specific access authentication.

Currently, MCPTT services focusing on voice have been introduced in the Public Safety Communication Network (PS-LTE) and Railway Integrated Wireless Network (LTE-R), but there is a growing need for next-generation mission-critical services for advanced and intelligent service implementation.

The Ministry of the Interior and Safety is planning to enhance disaster response capabilities by introducing MCVideo, MCData, and upgrading communication infrastructure according to the 'First Basic Plan for Public Safety Communication Network (2022-2026)'.

The International Union of Railways (UIC) and the European Union are also pursuing a project to upgrade the 2G-based European Railway Communication System (GSM-R) to the Future Railway Mobile Communication System (FRMCS) based on 5G mission-critical services.

This demonstration, led by the Korea Railroad Research Institute and applying NetCube's 5G network slicing processing platform, was part of the National Information Society Agency's '5G Convergence Service Testbed Demonstration' project. The technology was verified for its functions and performance at the 5G Specialized Network Testbed (Pangyo Hub) in cooperation with the Telecommunications Technology Association and was selected as an outstanding achievement in the 5G Convergence Service Testbed project.

Senior Researcher Sung-soo Park stated, "We plan to continue research to apply the developed technology not only in public sectors like public safety and railways but also in various private sectors such as manufacturing and logistics that are pursuing 5G specialized network implementation."

President Seok-yun Han of the Korea Railroad Research Institute commented, "Based on the government's 5G specialized network testing and verification support system, we successfully developed and verified top-tier K-Railway technology" and added, "We will continue to strive to secure world-class digital capabilities to realize Korea's digital strategy."
