Abstract: Techniques are provided for managing the provisioning of voice services to a user equipment (UE) in a fifth generation (5G) network. For example, the UE generates a registration request message that includes 5G mobility management (5GMM) capabilities of the UE that are indicative of whether the UE supports voice over internet protocol multimedia subsystem (IMS), and transmits the registration request message to a next generation radio acess network (NGRAN) node in the 5G wireless network. Based on the 5GMM capabilities, the NG-RAN node can determine whether voice over IMS can be provided to UE by comparing the 5GMM capabilities to capabilities of the NG-RAN node.

Abstract: Systems and methods of protecting an initial NAS message are described. The NAS message is encrypted using the home PLMN public key during initial registration with the network using a registration request message. An AMF of the serving PLMN sends a serving PLMN public key which is then used to encrypt information including an S-NSSAI of later initial NAS messages after initial registration is completed. The S-NSSAI may not be sent in the later initial NAS message if the S-NSSAI is provided at an access stratum level. The RRC message may contain an indication that the S-NSSAI is encrypted using the serving PLMN public key.

Abstract: In one embodiment, an apparatus of a User Equipment (UE) device includes memory storing non-public network (NPN) configuration information, a radio frequency (RF) interface, and processing circuitry coupled to the memory and the RF interface. The RF interface receives information broadcast by a radio access network (RAN) node of the particular NPN, where the information includes a NPN indicator indicating that the RAN node supports a NPN and NPN service information indicating services supported by the particular NPN. The processing circuitry establishes, in response to detecting the NPN indicator in the information received from the RAN node, a connection to the particular NPN based on the NPN configuration information and the NPN service information received from the RAN node.

Abstract: Systems and methods of protecting an initial NAS message are described. Depending on whether a security context for a serving PLMN is stored, the UE uses either a public key from the serving PLMN or a key from the security context to encrypt parts of the initial NAS message. An initial NAS message containing the encrypted parts is then sent to an AMF of the serving PLMN. The serving PLMN public key is transmitted via a SIB. Prior to transmission of the initial NAS message or in parallel with it, an RRC message is sent to the base station. The RRC message contains the UE identifier and/or a NSSAI encrypted using the serving PLMN public key.

Abstract: Systems and methods of providing UE capability are described. A capability ID is associated with the same Radio Capability information for multiple UEs. If the capability ID is validated at a network node, the UE provides the capability ID to a RAN node, which obtains the capability information from the network node after providing the received capability ID to the RAN node. The capability ID is received in an RRC Setup Complete, Security Mode Complete or Reconfiguration Complete message. The network node, if the Radio Capability information is not available, requests and receives the Radio Capability information and associates it with the capability ID, and marks that the capability ID as not validated until a threshold number of the UEs have provided the same Radio Capability information. The capability ID is based on a UE device type, manufacturer and software version.

Abstract: Devices, systems and methods for transitioning a UE to a new application server in response to a mobility event comprising, at a source application server handler: receiving an application ID (AC-ID) associated with an application client for a user equipment (UE); receiving a mobility event notification including a UE ID of the UE and a target data network access identifier (DNAI) to indicate a target edge data network to which a transition of a data connection for the application client is to be performed; encoding an outgoing transition request for transmission to a source application server to indicate the transition of the data connection from the source application server; and encoding an incoming transition request for transmission to a target application server handler (ASH) of the target edge data network to indicate the transition of the data connection to the target edge data network.
