LiveU continues to drive innovation as a key partner in dynamic 5G network slicing trials

5G partners are joining forces to try out live video using single and bonded modems. These were sent over 5G slices that were automatically and dynamically set up according to real-time analysis. The partners involved were LiveU, LM Ericsson, Nokia and University of Patras (UoP) under the Horizon Europe 5G-Solution project.

One of the most promising mechanisms in 5G Standalone (SA) networks is ‘slicing’. Essentially, this is the ability to provide the highest possible performance, or QoS, to authorized users end-to-end within the cellular radio and core network. This means that his QoS-centric applications, such as live uplink video transmission for news, sports, and even event coverage beyond, are likely to receive his QoS required for ultimate signal stability at a location. means high. But how to allocate and manage these slices and how can a 5G mobile operator provide his QoS level guaranteed to multiple broadcasters via specific slices at specific locations? Huh?

Baruch Altman, Head of LiveU’s 5G Technology Project“One of the technical obstacles to the widespread deployment of slices is the static/fixed allocation of resources (spectrum, QoS within network boundaries) and the dynamic per-demand management of slice allocation. So far, the theoretical 5G benefits of large-scale remote production have not been fully realized.”

In this trial, using a LiveU Multicam LU800 field unit and a network management process called Zero-Touch-Automation (ZTA), transmission over a 5G slice that was automatically set up according to real-time analysis was achieved. Each unit transmitted up to four independent camera feeds simultaneously by combining multiple modems, networks, or slices. One of them was a specially configured slice for a broadcaster’s uplink video post. The ZTA mechanism is dynamically allocated to his 5G slices in real time according to the LiveU unit’s transmission needs and the overall network load.

Ericsson’s specially designed ZTA mechanism identified changes in network performance in real time due to increased upload demand. Next, we notified our network management orchestrators (CDSO, Nokia) to set up a special upload-oriented slice and perform a network reconfiguration (deployed by UoP). The LiveU unit’s modem automatically identified and started using the newly available special slice, and the LiveU bonding algorithm began transmitting live video packets using this dedicated slice. By combining this slice into a “best effort” slice or commercial network, each LU800 can now transmit four video streams simultaneously with high quality and consistent bandwidth and latency. Combining special slices with other modems, networks, and bandwidth in real time helped maintain video continuity and overall QoS, reducing the spectrum required from new slices.

This study further demonstrated that even using adaptive ZTA with dedicated “guaranteed performance” slice allocation, multiple modems, networks and slices should be combined transparently and agnostically. bottom. Via conditions and any network configuration.

Altman continues. Currently, only cutting-edge solutions like LiveU’s field units can optimally leverage such advanced he 5G capabilities, supporting the efficient operation needs of network operators while providing immediate value to customers. can produce The outcome of this joint effort re-emphasizes LiveU’s leadership at the forefront of his 5G technology development for broadcast, sports, government and other customers. ”
