摘要： The present disclosure provides methods, entities, and computer readable media for non-3GPP access authentication. The method (1600) at a protocol translation entity includes: receiving (S1601), from a Non-3GPP access point, an authentication request message of a first protocol type for a UE that includes an identity of the UE; translating (S1603) the authentication request message of the first protocol type to a corresponding authentication request message of a second protocol type; and transmitting (S1605), to an entity for authentication, the corresponding authentication request message of a second protocol type that includes the identity of the UE.

摘要： Disclosed is a method and access management entity for selecting a session management (SM) entity for serving a wireless communication device (WCD) in a core network that comprises an access management entity serving the WCD and an anchor SM entity that controls a first user plane entity that handles a data session associated with the WCD in a first domain, and a second SM entity for controlling a second user plane entity in a second domain of the core network. The method is performed by the access management entity and comprises selecting—based on WCD information and SM domain information—the second SM entity as an additional intermediate SM entity to control a user plane entity in the second domain for handling the data session in the second domain; requesting the second SM entity to act as the additional intermediate SM; and receiving a session response message.

摘要： A method to operate a Network Function, Repository Function, NRF, to manage NF profiles of Session Management Functions (SMFs) in a communication system is provided that is configured to communicate with other network functions of the communications system through a network interface. The NRF receives NF profiles for the SMFs, wherein at least some of the NF profiles each include both a SMF identifier and a service area information for a respective one of the SMFs. After receiving the NF profiles, the NRF stores the SMF identifiers and the service area information of the NF profiles in a repository in memory. The NRF may also receive a NF discovery request for discovering SMFs. After receiving the NF discovery request, the NRF may retrieve from the repository at least one of the NF profiles respectively for at least one SMF based on content of the NF discovery request. The NRF communicates a NF discovery response containing the SMF identifier and the service area information of the at least one SMF.

摘要： Disclosed herein is a method performed by an AMF entity in a Visited Public Land Mobile Network, VPLMN, entity serving a roaming UE, the method comprises: obtaining, by the AMF entity, a subscribed UE-AMBR for the UE; sending, by the AMF entity, an Access Management, AM, Policy request message towards a Visited Policy Control Function, V-PCF, entity in the VPLMN to establish or update an AM Policy for the roaming UE; receiving by the AMF entity in response to sending the AM Policy request message, an AM Policy response message sent by the V-PCF entity and comprising Access and mobility related policy information that includes a serving network UE-AMBR for the UE decided by the V-PCF entity; and deploying the serving network UE-AMBR instead of the subscribed UE-AMBR by sending the policy control information including the determined UE-AMBR to a RAN node in the serving network.

摘要： According to one aspect of the present disclosure, a method of paging policy differentiation in a 5G telecommunications network is provided. A User Plane Function (UPF) receives downlink data for a target User Equipment (UE), and provides a data notification to a Session Management Function (SMF), the data notification comprising a Quality of Service (QoS) indicator, which the SMF uses to determine QoS Information (QoSI) that is sent to an Access Management Function (AMF). The AMF determines whether a paging policy selection should be performed by the AMF or by a Radio Access Node (RAN) that serves the target UE: if by the AMF, the AMF selects a paging policy based on the QoSI and sends a paging message to the RAN, which pages the UE; if by the RAN, the AMF provides paging policy information to the RAN, which selects a paging policy and pages the UE accordingly.
