  • Patent number: 12156025
    Abstract: Embodiments herein relate to e.g. a method performed by a network node for handling a communication of a user equipment, UE, in a wireless communication network. The network node transmits to a radio network node associated with the UE, a request message indicating a request for capability data for the UE, wherein the request message comprises a security indication, and wherein the security indication indicates data for setting up a secure connection to the UE.

  • Publication number: 20240214963
    Abstract: This disclosure combines the Attach and Tracking Area Update procedures into one new mobility procedure: the Registration procedure. One advantage of the proposed Registration procedure is that, if the new SHF is unable to obtain UE data from the old SHF the new SHF will nevertheless register the UE so that the UE does not have to perform another registration procedure (e.g., an Attach procedure).

  • Publication number: 20240187978
    Abstract: During PDN connection establishment in the EPC, a UE and a session management entity (SME) (e.g., PGW?C+SMF) exchange information. In case the SME supports more than one S-NSSAI, before the SME provides an S-NSSAI to the UE, the SME should check such that the selected S-NSSAI is among the UE's subscribed S-NSSAIs by retrieving the Subscribed S-NSSAI from a UDM using, for example, the Nudm_SDM_Get service operation.

  • Publication number: 20220345941
    Abstract: A method implemented by a Policy Control Function (PCF) of a Core Network (CN) node in a communications network includes receiving a request message from an Access and Mobility management Function (AMF). The request message includes a requested Data Network Name (DNN) designated by a wireless terminal in a Protocol Data Unit (PDU) session establishment request to the AMF. Responsive to the request message and to session-specific information, a selected DNN and a Session Management Function (SMF) index is determined. Each of one or more SMFs are registered with a Network Repository Function (NRF) of the CN node or a different CN node according to a corresponding SMF profile. The selected DNN and the SMF index are sent to the AMF to facilitate selection of one of the one or more SMFs via the NRF for establishment of the PDU session between the wireless terminal and the selected SMF.

  • Publication number: 20220303935
    Abstract: Systems and methods are disclosed herein for Access and Mobility Function (AMF) re-allocation. In one embodiment, a method for AMF re-allocation includes, at an initial AMF, receiving a registration request for a User Equipment (UE) from a Radio Access Network (RAN), deciding to initiate an AMF re-allocation procedure, sending the registration request to the RAN for delivery to a target AMF for the AMF re-allocation procedure, and sending a UE security context of the UE to another Network Function (NF). The method further includes, at the target AMF, receiving a message from the RAN wherein the message includes the registration request from the UE, obtaining the UE security context of the UE from the other NF, and performing protected NAS signaling related to a registration procedure for the UE using the UE security context of the UE.
