  • Publication number: 20220007182
    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.

  • Publication number: 20210368556
    Abstract: An apparatus and system for onboarding network behavior based on the type of UE and identification information are described. The identification information, if provided by the UE, is provided either during an initial registration procedure or a configured PDU session establishment procedure and includes one or both of an SO-SNPN and provisioning server identity. The UE, if identification information is provided by an SMF, overwrites the default identification information stored in the UE and performs provisioning server discovery on a provisioning server identity in the identification information. If the UE does not store provisioning server identification, the UE constructs a well-defined FQDN to perform provisioning server discovery.

  • Publication number: 20210352467
    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.

  • Patent number: 11172413
    Abstract: Systems and methods of providing 5G access for a UE are generally described. The UE is simultaneously connected via dual radio operation to a legacy and 5G access system. The UE mobility management states for the access systems are independent of each other. The EPC and 5G CN share an HSS and may share a IP anchor. When handover occurs between access systems, the IP address is retained and the IP anchor used when the UE transmits an Attach Request having a Handover Attach Request Type and otherwise a new IP address is provided and the HSS but not the IP anchor is common between the access systems. The 5G eNB to which the UE is connected is standalone and connected to the 5G CN or dual mode and connected with an EPC via an LTE anchor in addition to the 5G CN.

  • Patent number: 11160006
    Abstract: A user equipment (UE) can include processing circuitry configured to decode system information including access barring parameters for one or more access categories for accessing a cell of a next generation Node-B (gNB). A network access attempt is detected by a control plane layer of the UE that is higher than a Radio Resource Control (RRC) layer. The processing circuitry map s, using a Non-Access Stratum (NAS) layer of the control plane, the network access attempt to at least one access category of a plurality of available access categories based on mapping rules. The processing circuitry performs an access barring check procedure for the mapped at least one access category based on the access barring parameters. Upon determining that access to the cell is not barred, a NAS message is encoded for transmission to an Access and Mobility Management Function (AMF), e.g. an Attach Request message to perform an attach procedure.

  • Patent number: 11019538
    Abstract: User equipment (UEs) can fallback to a legacy system, such as an evolved packet system (EPS), from a fifth generation system (5GS). For example, a UE camps on the 5GS network by default. When an indicator of a voice call is detected, the UE performs a fallback to EPS for a duration of the voice call. After the voice call, the UE can return to the 5GS. In another example, the UE detects an emergency session request (e.g., internet protocol multimedia subsystem (IMS) emergency session request). The UE performs a fallback to EPS for a duration of the emergency session. After the emergency session is complete, the UE can return to the 5GS. The solution can operate with UEs that operate in either Single Registration (SR) mode embodiments or Dual Registration (DR) mode embodiments. Depending on the embodiment, the UE can perform a handover or redirection to the legacy system (such as E-UTRAN).
