6G-XR

Based on MATSUKO holographic solution, the re-design of the holographic session manager relying on the network control plane (IP Multimedia Subsystem (IMS) and evolutions towards 6G) has two main objectives: 

1. User perspective: integrating holographic communications smoothly into the dialler app as an evolved communication service in 6G beyond voice (Voilce over Long Term Evolution (VoLTE) and Voice over New Radio (VoNR)). 
2. Technical perspective: We are looking to maximise the solution's robustness and scale by relying on the network for session management aspects. This will result in performance and functional improvements (QoS, roaming, interconnection, and other benefits that IMS brings).

MATSUKO will explore the integration of enablers into the Mobile Network Operator (MNO) standard architecture. The holographic communications services will be connected and integrated with the IMS Data Channel (DC) and 6G XR-Ready Control Plane. This will involve moving media user plane components to the Edge and integrating the identity and session management control functions with the 6G Comms Control Plane APIs (both on the device and network side). Establishing an analogy to 5G will be similar to the concept of IMS DC device-side APIs and Communications Platform as a Service (CPaaS) network APIs on the network side.

MATSUKO architecture will be adapted to meet 6G-XR requirements in the following ways:

• Integration of IMS Data Channel on both server and client sides
• Adaptation of the MATSUKO signalling service for IMS signalling
• Implementation of the Notification Service to inform Holographic Sender about a new call
