KT's 5G Innovations @'5G Vision Forum'
09/25/2015 | By Netmanias (tech@netmanias.com)

At a forum hosted by 'media it' on September 10, titled "5G Vision Forum", Dr. Haseong Kim from Institute of Convergence Technology at KT made a presentation on the company's 5G vision and innovations titled "Innovations and Changes towards 5G".

 

 

5G Concept  

  • 5G network should support Big Pipe, Massive Connectivity, and Near-Zero Latency
  • Mobile cloud computing platform can offer reduced TCO as well as higher flexibility and scalability

 

 5G Network Vision

  • To bring multi-RAT interworking (LTE / WiFi/ 5G (<5GHz) / 5G (mmWave)) technology, and unified access network that combines wired and wireless access networks, by leveraging its powerful wired infra.

 

 

 5G Innovations

&

1) Distributed Core Network

Core nodes (user plane) are deployed forward at RAN for handling low-latency service and huge traffic.    

  • Mobile core units are divided into two: user plane core unit (MCU-UP) and control plane core unit (MCU-CP). 
  • MCU-UP is placed at RAN (closer to cell sites) along with App/Cache server.  
  • MCU-CP will be operated by SDN controller.

 

2) Network Slicing 

  • Logically-separated 5G services (or slices) on 5G unified network

&

3) 5G C-RAN Architeture

  • Redesign of function split between DU and RU to support massive MIMO 
  • DU/RU in 4G -> CU/AU in 5G
