摘要： Example embodiments presented herein are directed towards a wireless device and core network node, as well as corresponding methods therein, for managing a data flow between a network access type 1 and a network access type 2. According to some examples, access type 1 may be a 3GPP access and access type 2 may be a non-3GPP access. The wireless device is connectable to both the networks of access types 1 and 2.

摘要： A method performed by a serving Access and Mobility Management Function (AMF) serving a wireless communication device. The method includes receiving, from a target AMF, a request for information regarding the wireless communication device. The method also includes submitting, in reply to the request for information, a current user equipment (UE) context of the wireless communication device and an identifier of an ongoing non 3rd Generation Partnership Project (non-3GPP) access Protocol Data Unit (PDU) session for the wireless communication device. The method further includes notifying a Non-3GPP Interworking Function (N3IWF) to remove the current UE context, wherein the N3IWF is configured to enable the wireless communication device to attach to the core network over non-3GPP access.

摘要： A method of protecting WLAN Control Protocol (WLCP) message exchange between a Trusted WLAN Access Gateway (TWAG)(112) of a Trusted WLAN Access Network (TWAN)(110) and a User Equipment (UE)(101) are provided. The method comprises deriving, by an Authentication, Authorization, and Accounting, (AAA) Server(103) of an Evolved Packet Core (EPC) network which is interfaced with the TWAN, and by the UE, a Master Session Key (MSK) and an Extended MSK (EMSK), sending, from the AAA Server to a Trusted WLAN AAA Proxy (TWAP)(113) of the TWAN and an Access Point (AP)(111) of the TWAN, the MSK or a key derived from at least the MSK, and deriving, by the TWAN or by the AAA Server, and by the UE, from the MSK, the EMSK, or the key derived from at least the MSK or the EMSK, a key for protecting the WLCP message exchange.—Corresponding devices, computer programs, and computer program products are further provided.

摘要： A method is performed in a network control entity that manages network connections for a network. The method includes receiving a network attachment request from a network access entity or a user equipment for connecting the user equipment to the network. The method further includes obtaining a network partition ID associated with the UE, the network partition ID identifying a network partition that includes a predetermined group of network entities included in the network. The method also includes transmitting, to a network storage entity, a notification containing the network partition ID.

摘要： An Access and Mobility Management Function (“AMF”) can include processing circuitry and memory coupled to the processing circuitry. The memory has instructions stored therein that are executable by the processing circuitry to cause the AMF to perform operations. The operations include determining that selection of a Session Management Function (“SMF”) from a plurality of SMFs of a communications system is needed. The operations further include, responsive to the determination, generating a network function (“NF”) discovery request including a service area indication requesting service area information for discovered SMFs. The operations further include communicating the NF discovery request toward a NF Repository Function (“NRF”). The operations further include receiving a NF discovery response including SMF identifiers and service area information for a list of SMFs. The operations further include selecting the SMF from the list of SMFs.
