Agenda

Quick update on 5G-MAG Reference Tools

• Progress implementing the 5G Media Streaming specifications:
  • 5G-MAG Reference Tools at a glance: https://github.com/5G-MAG/Getting-Started/wiki
  • https://github.com/5G-MAG/rt-5gms-application-function/releases/tag/rt-5gms-application-function-v1.3.0
  • https://github.com/5G-MAG/rt-5gms-application-server/releases/tag/rt-5gms-application-server-1.1.2
  • https://github.com/5G-MAG/rt-5gms-media-session-handler/releases/tag/rt-5gms-media-session-handler-v1.0.0
  • https://github.com/5G-MAG/rt-5gms-media-stream-handler/releases/tag/rt-5gms-media-stream-handler-v1.0.0
  • https://github.com/5G-MAG/rt-5gms-application/releases/tag/rt-5gms-application-v1.0.0
  • https://github.com/5G-MAG/rt-5gms-common-android-library/releases/tag/rt-5gms-common-android-library-v1.0.0

  • End to End Setup for 5G Media Streaming (Android)
• Early plans to implement 5MBS, including MBS User Services.
  • Isolate the development of MBS User Services wrt MBS Core and RAN features
  • Reuse of existing platforms such as Open5GS and srsRAN
• Follow up on MBMS / 5G Broadcast
  • With the basic 5GMS functionalities in place, a low hanging fruit may be 5GMS over eMBMS (+ integration of Android MBMS Client)
