MEC in 3D-Networks: Supporting Application Controlled QoS

Multi-Access Edge Computing (MEC) applied to three-dimensional (3D)-Networks comprising space, air, and ground layers, bear the potential to combine benefits of all these domains and globally provide low latency services. These networks leverage technologies such as non-terrestrial networks (NTN) and advanced computing frameworks to provide real-time services and extend connectivity to remote regions. Especially for MEC-App developers, knowledge of the underlying network topology and link characteristics is required to meet QoS targets, which has not been considered by current standardization. Based on the smart agriculture and video distribution use cases, we investigated on MEC in 3D-Networks, the architectural enablers, and necessary extension of current standards including mobility. For this we reviewed the current Application Programmable Interfaces (APIs) of the ETSI MEC standard and propose updates. Main update is the inclusion of topology information that can be used by MEC applications to achieve low latency and ultra-reliable services.
