METHOD AND APPARATUS FOR UE AND APPLICATION FUNCTION SESSION PROTECTION FOR MODEL TRANSFER

Abstract

In accordance with an example embodiment, a UE performs maintaining an AKMA, context including a UE identifier, an AKMA anchor key KAKMA, and a primary AKMA key identifier, A-KID; receiving from an application function, AF, a secondary AKMA key identifier, A-KID'; and validating the AF for the UE using the AKMA key identifier A-KID. The validating includes: obtaining from the secondary AKMA key identifier A-KID' an AKMA temporary UE identifier A- TID; and verifying whether the A-TID was included in the primary AKMA key identifier A-KID. If the verifying is positive, then the UE establishes an application session with the AF; and receives an artificial intelligence, AI, model from the AF; or otherwise rejects the application session with the AF.
