The executed instructions further cause the processor to select an authentication method based upon the authentication request. In addition, the executed instructions cause the processor to transmit an authentication challenge message to the non-3GPP device. Moreover, the executed instructions cause the processor to receive the authentication response from the non-3GPP device. Furthermore, the executed instructions cause the processor to verify the authentication response.

Abstract: Systems and methods to authenticate a Non-Fifth Generation Capable (N5GC) device on a Residential Gateway (RG) include a wireline access network comprising the RG and a wireline-access gateway function (W-AGF). The RG connects to the W-AGF using a termination system (e.g., a Cable Modem Termination System (CMTS) and the like) to relay N5GC device messages received at the RG to the W-AGF and vice versa. During a registration/authentication procedure for the N5GC device, the W-AGF generates a Registration Request message on behalf of the N5GC device and sends the Registration Request message to an Access & Mobility Management Function (AMF) of a Fifth Generation (5G) core network. The Registration Request message includes an indication that the N5GC device lacks 5G capabilities (e.g., is N5GC). In response to the Registration Request message, the system causes the N5GC device to be authenticated at least partly in response to the Registration Request message.

Abstract: A client-side electronic device includes a receiver, a processor, and a memory. The receiver communicates with a message server over a communication medium of a communication network.

Abstract: Aspects of the invention pertain to methods and devices that allow user equipment (UE), such as for example wireless devices, to reconfigure their respective antennas in a dynamic manner to allow connection to additional or fewer logical networks, also being referred to as network slices. Changing the configuration of the array of antennas may include changing an existing configuration, or allocation, of the antennas that are currently communicating with a first number of logical networks into a different configuration of antennas for communicating with a second, different second number of logical networks. In some cases this may mean that antennas that were allocated for communicating with a primary logical network are re-allocated for communicating with a second logical network, with other antennas remaining in communication with the primary logical network.
