Rapporteur:  Mr. Gupta, Nishant

Edge Computing is a network architecture concept that enables cloud computing capabilities and service environments to be deployed at the edge of the cellular network. It promises several benefits such as lower latency, higher bandwidth, reduced backhaul traffic and prospects for several new services. This technical report identifies the key issues and corresponding application architecture and related solutions with recommendations for the normative work.
The aspects of the study include identifying architecture requirements (e.g. discovery of edge services, authentication of the clients), supporting application layer functional model and corresponding solutions to enable the deployment of applications on the edge of 3GPP networks, with no impact to edge-unaware applications on the UE and minimal impact to edge-aware applications on the UE.
