Vulnerable Road Users (VRU) scenario

The Vulnerable Road Users (VRU) scenario represents a mission-critical oriented scenario where reliability, latency and in-order of delivery are the main representative QoS requirements that network services need to comply. The use case scenario is divided into two user stories: (1) presence awareness of VRUs in potentially dangerous situations; and (2) collision risk warning of VRUs.

In the first user story, the idea is to explore use case scenarios without Line-of-Sight (LOS) between pedestrians and drivers, in crosswalks, zebra crossing and other similar situations. Using a combination of information from wireless detection mechanisms and surveillance cameras, drivers receive awareness messages via roadside units or other attached systems, reporting a possible dangerous VRU nearby. This user story may involve one or multiple vehicles, representing communication scenarios between V2I and/or V2P.

The second user story represents a more critical use case where the possibility of collision may occur, representing an extension of the first user story in a more critical scenario. Instead of only detecting the presence of VRUs and notify drivers about this risk, in this scenario, the information collected by several systems nearby should be able to infer the risk of collision. Additionally, there is an increase of sensor information, in order to increase the accuracy in the collision detection. VRUs are also watched by vehicle sensors, and vehicles can share information with each other and/or Road Side Units (RSUs).

Warning notification should be shared with drivers using the roadside units and 3GPP systems.

Under the scope of SNOB-5G these user stories will be able to test and measure the backhaul network services performance, taking into account the need for high reliability and low latency, with high mobility patterns, represented by the drivers and VRUs.

Multi-RAT Real-time media streaming aided by distributed computation scenario

Highly Media Covered events are events where millions of people consume its content in real time and simultaneously. Events such as sport matches, music concerts or public speaking conferences depending on the stakeholders might generate a big public interest resulting in a considerably high number of users requesting for the real time media streaming of the event with as high quality as possible.

This poses a high challenge for network resources to be able to cope with such a demand for such a wide number of users. In the scope of this use case, it is expected that SNOB-5G solution enables for the deployment in real time of virtual functions that allow for the transcoding and caching of media content as close to consumption as possible and based on the demand of users.

These functions will not only ensure that consumers will perceive the event in real time and in ultra high quality, but also that the network resources consumed are considerably reduced by enabling that the same stream is shared between multiple users instead of each user requesting and receiving its own dedicated media stream with the same contents.

The network resource efficiency will be as high as how close to the consumers these functions are applied being one of the most important topics to be addressed in this use case.
