摘要： The embodiments herein relate to a method performed by a PGW (108) for handling a UEs (101) access to an EPC service via a non-3GPP access network (103). During a request for connecting the UE (101) to the non-3GPP access network (103), the PGW (108) receives identity information which indicates an identity of an AAA node (710) from a non-3GPP access gateway (705). The PGW (108) selects the AAA node (710) which was indicated in the received identity information. The PGW (108) transmits, to the selected AAA node (710), a request message for the UE (101). The request message is a request for authorization of the UE (101) to access the EPC service via the non-3GPP access network (103).

摘要： A Voice Over Wifi (VoWifi) split Protocol Data Unit (PDU) Session handover is provided. In embodiments described herein, a VoWiFi session is established via a Non-3GPP N3IWF over a 5G Core, and a handover to 3GPP access through the 5G System is initiated. During handover and based on local configuration, the Packet Data Network Gateway-Control Plane (PGW-C) and Session Management Function (SMF) (PGW-C+SMF) accepts the PDU Session transfer towards the User Equipment (UE) and Next Generation Radio Access Network (NG-RAN) by means of setting up only the Quality of Service (QoS) Flow associated with a default QoS Rule. The PGW-C+SMF initiates set up of the QoS Flow for Internet Protocol (IP) Multimedia Subsystem (IMS) voice using the PDU Session Modification procedure after the NG-RAN successfully allocates resources for the transferred PDU Session and the confirmation has reached the PGW-C+SMF.

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： Methods and apparatuses for mobility between different communication systems are disclosed. According to an embodiment, a session management function (SMF) sends, to a service provider, a request for registering information related to the SMF to the service provider. The information related to the SMF comprises information indicating or derived from an Internet protocol (IP) address of a packet data network (PDN) gateway (PGW) control plane (PGW-C) that is combined together with the SMF. The SMF receives, from the service provider, a response to the request.

摘要： In one aspect, a method for a packet gateway node (PGW) is disclosed. The PGW being adapted for (a) communicating with at least a serving gateway node, SGW, (b) receiving and forwarding downlink data packets to a user entity, UE, and (c) communicating with a mobility management entity, MME. In one embodiment, the method comprises: the PGW, when receiving a downlink user plane data packet destined for the UE on a Packet Data Network, PDN, connection associated with a restarted SGW, determining if the PDN connection has not yet been relocated to a new SGW, and, if so, selecting at least one SGW from a set of SGWs including the restarted SGW or another SGW and transmitting a control plane signal to at least one of the selected SGWs, the control plane signal identifying at least the UE.

摘要： A method for assigning a cellular network identity. The method comprises receiving (222), in a user equipment capable to attach to a cellular network and a wireless local area network, a unique representation of a user equipment context of the user equipment and in what cellular network node the user equipment is or is going to be attached, from a network node. The unique representation is labelled (224) as a cellular network identity and cellular network identity is stored (226) a pseudonym identity and/or a fast re-authentication identity in a memory in the user equipment.

摘要： One embodiment of the present disclosure relates to a method implemented by a first gateway node for processing an emergency call from an untrusted non-3GPP access network. The method comprises: receiving an emergency call request initiated from a terminal device over an untrusted non-3GPP based access network; detecting an event of the emergency call depending upon the emergency network access identifier included in the request message; selecting for the terminal device an emergency access point name that identifies an external network providing an emergency call service; and establishing for the terminal device an emergency call session with a second gateway node interfacing with the external network which is identified by the selected emergency access point name. According to an aspect of the present disclosure, there are provided corresponding methods and devices.
