Abstract: In one embodiment, a method is performed. A device may receive a registration request from a user equipment (UE) device associated with a category. The device may receive a registration response from an access and mobility function (AMF). The registration response may comprise a group identifier associated with the category. The device may select resources from a resource pool based on the group identifier. The resource pool may be dedicated for use for emergency communications. The device may allocate the selected resources to the UE device.

Abstract: In one embodiment, a system, apparatus, and method are described for requesting access authorization from an access network access point (AP) via an access network interface, generating at a processor a public-private key pair to be used to generate a cryptographically generated address (CGA) upon receiving the access authorization, sending a secure neighbor discovery (SeND)—neighbor solicitation (NS) to the AP via the access network interface after the public-private key pair has been generated, receiving a signed user location information (ULI) from the AP in response to the SeND-NS, and sending the signed ULI to one of a 3GPP mobility controller or an emergency service via a 3GPP network interface. Related systems, apparatuses, and methods are also described.
