Abstract
A relay wireless transmit/receive unit (WTRU) may receive a direct communication request (DCR) from a remote WTRU requesting connectivity service (e.g., connectivity session parameters such as single-network slice selection assistance (S-NSSA!), data network name (DNN)), The relay may determine that the connectivity session for the service is subject to a secondary authentication and authorization (A&A), based on an indication associated with the connectivity session if already established and/or an indication associated DN from relay proximity service (ProSe) configuration. Based on the determination, the relay may trigger a network-controlled authorization for the remote WTRU. The relay WTRU may send a direct communication accept (DCA) message including a pending secondary A&A. and configure a traffic filter associated with the connection (e.g., a PC5 link) to discard data traffic from the remote WTRU until a successful completion of the secondary A&A.
