Interest in using cellular connectivity to support Unmanned Aerial Systems (UAS) is strong, and the 3GPP ecosystem offers excellent benefits for UAS operation. Ubiquitous coverage, high reliability and QoS, robust security, and seamless mobility are critical factors to supporting UAS command and control functions. In parallel, regulators are investigating safety and performance standards and Registration and licensing programs to develop a well-functioning private and civil UAS ecosystem which can safely coexist with commercial air traffic, public and private infrastructure, and the general population. Enabling UAS identification and tracking would allow authorised users (for example air traffic control, public safety agencies) to query the identity and metadata of a UAV and its UAV controller via Unmanned Aerial System Traffic Management (UTM). The UTM stores the data required for UAS(s) to operate. Air traffic control agency uses the UTM server to authorise, enforce, and regulate UAS operation. This would assist in controlling airspace and for public safety applications. The present document identifies the use cases and documents the derived potential requirements for meeting the business, security, and public safety needs for the remote identification and tracking of UAS linked to a 3GPP subscription.
