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.

Abstract: 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.

Abstract: Methods and apparatuses for mobility between different communication systems are disclosed.

The SMF receives, from the service provider, a response to the request.

Abstract: A technique is provided for synchronizing a first call state of a network component and a second call state of a mobile device. The mobile device is connectable to a network via a first Radio Access Technology (RAT) and a second RAT. The network forwards towards a callee an invitation for a call originating via the first RAT from the mobile device. The network sends a first message corresponding to a callee response towards the mobile device. The network component triggers a transfer of the call session of the mobile device from the first RAT to the second RAT. The first call state is set by the response of the callee. Information indicative of the second call state is received from the mobile device, and a second message for changing the second call state by the response is provided to the mobile device when inconsistent first and second call states.
