Abstract: Systems, methods, apparatuses, and computer program products for emergency sessions, such as emergency calls, using a relay provided by proximity services are provided. For example, a method may include indicating, in a relay discovery procedure, a capability of a relay user equipment to support an emergency call. The method can alternatively or in addition include receiving, in the relay discovery procedure, an indication of a need of a remote user equipment to conduct an emergency call.

Abstract: A H-SMF receives, from a V-SMF in a VPLMN, a join request originating from a UE roaming in the VPLMN to join a multicast multicast and broadcast services (MBS) session, and determines whether the UE is authorized to join the multicast MBS session based upon a local configuration in a home public land mobile network, information received from an application function during establishment of the multicast MBS session, and/or user subscription data received from a user data manager. The H-SMF at least one of: transmits to the V-SMF, if the UE is authorized, an acceptance response configured to establish at least one unicast QoS flow corresponding to multicast QoS flow information received from a H-MB-SMF, or, if the UE is not authorized, a rejection response comprising error cause information indicating that the UE is not authorized to join while roaming.
