US 12,593,204 B2 · Systems and methods for authorization of proximity based services

Abstract

Presented are systems and methods for authorization of proximity based services. A first wireless communication device may send, to a second wireless communication device, a message to access a network via the second wireless communication device as a relay node, using at least one authentication and key management for applications (AKMA) service. The message may include an AKMA key identifier (A-KID) and a freshness parameter. The first wireless communication device may generate a validation token to validate against another validation token of the second wireless communication device. The first wireless communication device may generate the validation token using the freshness parameter and a proximity based service function (PBSF) key (KPBSF).
