Section: 5.1.1 Description
Content: As a UAS requests permission to access UAS data services from an MNO, the MNO performs a secondary check (after or in parallel to the initial mutual authentication) to establish the UASs credentials to operate. The MNO is responsible for transporting and potentially adding additional data to the request to operate from the UAS to an Unmanned Aerial System Traffic Management (UTM). Note that the UTM is a 3GPP entity. This UTM is responsible for the authorization of UAS to operate and checks the credentials of the UAS and UAV operator. One option is that the UTM is operated by air traffic control agencies. It stores all the data regarding the UAV, UAV controller and their live location. If the UAS fails any part of this check, the MNO may refuse service to the UAS and hence deny permission to operate. Figure 5.1.1-1: Initial authorisation to operate
