摘要: A method performed by an Access and mobility Management Function (AMF). The method includes receiving from a Session Management Function (SMF) a request to establish User Plane (UP) for a user equipment's (UE's) protocol data unit (PDU) session. The request includes information indicating an access type. The method also includes, in response to the request, performing the steps of: determining that the UE is in the idle state with respect to both a 3GPP access and a non-3GPP access and, as a result of determining that the UE is in the idle state with respect to both a 3GPP access and a non-3GPP access, the AMF initiates paging of the UE by the 3GPP access, the paging initiation comprising transmitting to a Radio Access Network, RAN, node a page request to page the UE.

摘要: In a method for providing, for a terminal device, a service or service component requiring a first packet-forwarding treatment, a network node hosting a policy decision function determines that a dedicated bearer for carrying the traffic associated with the service or service component requiring the first packet-forwarding treatment cannot be used. This occurs when the service is initiated or, in the alternative, for an ongoing service. The service or service component is then initiated or, in the alternative, maintained, using a fallback bearer allowing the traffic associated with the service or service component to be carried with a second packet-forwarding treatment differing from the first one. The invention also relates to a method carried out, in such a context, by a network node hosting an application function, and to computer programs, computer program products and storage mediums for carrying out such methods.

摘要: The embodiments herein relate to a method in a gateway node for handling a RAN-CN data connection between the gateway node and a RAN node in a communications system. The gateway node receives a data suspend indication indicating that at least one RAN-CN data connection for the UE should be suspended. When the data suspend indication has been received, the gateway node stores resume information associated with the RAN node. The gateway node suspends the RAN-CN data connection according to the received data suspend indication. The gateway node receives a data resume indication indicating that the at least one RAN-CN data connection for the UE should be resumed. The gateway node resumes the at least one RAN-CN data connection for the UE using the stored resume information.

摘要: A method performed by a PGW for handling a UEs access to an EPC service via a non-3GPP access network. During a request for connecting the UE to the non-3GPP access network, the PGW receives identity information which indicates an identity of an AAA node from a non-3GPP access gateway. The PGW selects the AAA node which was indicated in the received identity information. The PGW transmits, to the selected AAA node, a request message for the UE. The request message is a request for authorization of the UE to access the EPC service via the non-3GPP access network.

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: The invention relates to methods and devices for enabling relocation of Access and Mobility Management Functions (AMFs). In an aspect of the invention a method performed by a Non-3rd Generation Partnership Project (3GPP) Interworking Function (14, N3IWF) enabling a wireless communication device (10) to attach to a core network (100) over non-3GPP access, to facilitate re-location of the wireless communication device (10) from an Access and Mobility Management Function (13, AMF) currently serving the wireless communication device (10) over non-3GPP access to the core network (100), to a target AMF (21) which is to serve the wireless communication device (10) over 3GPP access to the core network (100). The method comprises receiving (S119a), from the target AMF (21), a request to redirect any further signalling of the wireless communication device (10) from the currently serving AMF (13) to the target AMF (21); and redirecting any signalling of the wireless communication device (10) to the target AMF (21).

摘要: Systems and methods are disclosed for Network Function (NF) discovery between different network such as, e.g., different Stand-alone Non-Public Networks (SNPNs). In one embodiment, a method performed by a first Network Repository Function (NRF) comprises receiving a discovery request from a NF service consumer for one or more NF profiles of one or more NF instances deployed in a separate entity, the discovery request comprising a realm or domain name of an associated User Equipment (UE). The method further comprises identifying a second NRF in a separate entity based on the realm or domain name of the associated UE and sending a discovery request to the second NRF for the one or more NF profiles of the one or more NF instances deployed in the separate entity. Corresponding embodiments of a first NRF are also disclosed.

摘要: A method performed in a mobility management node includes the mobility management node receiving a first Packet Data Network (PDN) activation request from a wireless local area network (WLAN) access gateway, the first PDN activation request specifying an access point name (APN) and a tunnel endpoint identifier (TEID) parameter for identifying the WLAN access gateway, the WLAN access gateway connected to a user equipment (UE). The method further includes in response to receiving the PDN activation request, the mobility management node (i) selecting a Packet Data Network Gateway (PGW) based on the specified APN, (ii) generating a second PDN activation session request that includes the TEID parameter for identifying the WLAN access gateway, (iii) selecting a serving gateway (SGW), and (iv) forwarding the second PDN activation request to the selected SGW.
