Abstract: Systems and methods for supporting multiple uncrewed aerial vehicle (UAV) Service Suppliers (multi-USS) are described. The methods may be performed by a wireless transmit/receive unit (WTRU) including a UAV application enabling (UAE) client located in the UAV with the method performed with the UAV in-flight. Steps may include: sending a registration request to a UAE server, the registration request including an indication of multi-USS capability; receiving a registration response message that includes an indication that the UAE server supports multi-USS capability; receiving a multi-USS configuration request that includes multi-USS configuration parameters related to conditions under which the UAE client may initiate a USS change and a list of allowed USSs; sending a multi-USS configuration response; and performing a multi-USS change and sending a multi-USS change notification based on the multi-USS configuration parameters.

Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products for concealing a subscription identifier. The subscription identifier may be padded with a random number of characters. The padding may use characters not usable for the subscription identifier. The padded subscription identifier may be encrypted and output, possibly with an indication of the padding method used and, in an embodiment, an indication of the number of padding characters. The subscription identifier may be a user identifier, e.g., in a 5G network in which a wireless transmit/receive unit can conceal its identifier.
