Abstract: A user equipment (UE) may attempt to access an edge data network. The UE generates a first credential based on a second credential, the second credential generated for a procedure between the UE and a cellular network, generating an identifier corresponding to the first credential, and generates a multi-access edge computing (MEC) authorization parameter. The UE then transmits an application registration request message to a server associated with an edge data network, the application registration request message including an indication of the first credential, the identifier corresponding to the first credential and the first authorization parameter. The UE then receives an authentication accept message or an authentication reject message from the server associated with the edge data network.

Abstract: A network component communicating with a user equipment (UE) and a server. The network component receives a first packet from the UE, wherein the first packet indicates to the network component that the network component is to perform operations on behalf of the UE to maintain a persistent connection, receives a second packet from the server and determines whether to transmit a signal to the UE based on the second packet received from the server. A UE having a transceiver and a processor. The UE transmits a first packet to the network component, wherein the first packet indicates to the network component that the network component is to perform operations on behalf of the UE to maintain a persistent connection, identifies an out of service (OOS) event, receives registration information from the network component and registers with the server based on the registration information received from the network component.

Abstract: Techniques to protect subscriber identity in messages communicated between a user equipment (UE) and a cellular wireless network entity by using multiple ephemeral asymmetric keys are disclosed. The UE determines multiple ephemeral UE public and secret key pairs, while the cellular wireless network entity provides a network public key to the UE. The network public key may be updated over time. Multiple encryption keys based on the multiple ephemeral UE secret keys and the public network key are derived and used to encrypt a subscription permanent identifier (SUPI) to generate multiple subscription concealed identifiers (SUCIs). Each SUCI is used only once for messages communicated to a cellular wireless network and discarded after use. New SUCI are generated when the network public key is updated.

Abstract: A device, system, and method performs a Voice over Long Term Evolution (LTE) (VoLTE) call setup procedure. The device includes a transceiver establishing a connection with a LTE network and an Internet Protocol (IP) Multimedia Subsystem (IMS). The device includes a processor executing a VoLTE call application with a further user equipment, receiving an input to execute the VoLTE call application, and generating a data packet including an indication to trigger a dedicated bearer establishment procedure. The transceiver transmits the data packet to one of the LTE network and the IMS. The indication triggers the dedicated bearer establishment procedure to be performed during a Session Initiation Protocol (SIP) signal exchange procedure.

Abstract: Disclosed are embodiments for authentication and authorization in a 5G network between an edge enabler client (EEC) of a UE and an edge configuration server (ECS). The embodiment include performing primary authentication with the 5G network to obtain a KAUSF; generating a Kedge and a Kedge ID using the KAUSF and a subscription permanent identifier (SUPI); providing the Kedge and the Kedge ID to the EEC to cause it to compute a MACEEC using the Kedge and an EEC ID; and sending to the ECS an application registration request, the application registration request including the EEC ID, MACEEC, and Kedge ID.

Abstract: Disclosed are embodiments of a user equipment (UE) configured to communicate in a 5G network and to perform authentication between an edge enabler client (EEC) of the UE and an edge configuration server (ECS) or an edge enabler server (EES) based on an architecture for authentication and key management for applications (AKMA). The techniques include performing primary authentication with the 5G network to obtain a KAUSF; generating a KAKMA and an A-KID; providing to the EEC the KAKMA and an EEC identifier (ID) for the EEC to generate a Kedge, the KAKMA and the EEC ID being used by the EEC to compute a MACEEC; and sending to the ECS or the EES an application registration request, the application registration request including the EEC ID, the MACEEC, and the A-KID.
