WP3:This WP aims to provide agile communication and networking solutions for TI services in the Network Domain. The communication between the operator and teleoperator can cross radio access network (RAN), transport network and core network in 5G and next generation communication system. Therefore, an E2E multidomain orchestration with optimal 5G/B5G network configuration is vital to establish TI services offering the required QoS/QoE/QoT. In addition, as TI services require communication of multi-modal sensor data (visual/auditory/haptic), which have different requirements regarding sampling rate, transmission rate, latency, reliability and others10, it requires the network to support at least uRLLC traffic (e.g. haptic data) and eMBB traffic (e.g. 3D video stream). From a radio resource management and information theory perspective, multiplexing of large video packets (low update rate) with small haptic packets (high update rate) requires careful consideration of their characteristics. Furthermore, the different data use different error control schemes and congestion control methods. Hence, the significant communication and networking challenges are how to support highly demanding and diverse information flows and to meet their processing and control needs, while keeping the network operating at optimal points in the latency, resilience and throughput trade-off hyperspace. Fortunately, TI services often provide a certain amount of flexibility on how the service functions can be configured and operated11. For example, TI services can trade different haptic operation modes for dynamics or precision against robustness towards network latency. That opens the opportunity for a collaborative network and service configurations for TI services, which can be enabled by 5G and beyond, being a flexible joint networking and computing platform.
