At a glance
- Release 18: GA4RTAR creates the architecture (TS 26.506); iRTCW creates the protocols and APIs (TS 26.113); 5GMS_Pro_Ph2 creates the APIs shared with 5GMS (TS 26.510).
- Release 19: 5G_RTP_Ph2 adds PDU handling and marking enhancements to the Dynamic Policy API; iRTCW adds media capability and metadata support; AMD-ARCH-MED adds reference point M13 to the generalised architecture.
- Release 20: two work items on application energy consumption list TS 26.506 and TS 26.113, and a study looks at QUIC-based media delivery for real-time communication.
