摘要： The embodiments herein relate to a method in a Gn/Gp SGSN (111) for providing handover management. The Gn/Gp SGSN (111) provides a handover for a UE (101) to and from a non-3GPP and 3GPP by utilizing a PDP context that was previously created for the UE (101) during an attach procedure. The previously created PDP context is for a previously serving PGW (119).

摘要： Systems and methods relating to establishment of a Packet Data Unit, PDU, session over a Non 3GPP Access to a 3GPP network and transmitting IP data and non-IP data are provided. A method of operation of a wireless device is provided and comprises sending to an AMF over an N3IWF a PDU session request to establish a PDU session to transport one of IP data or non-IP data over an established first IPsec, Security Association, SA, establishing an IPSec Child SA, for the PDU session and associating the IPSec Child SA to a PDU session then encapsulating the data using ESP encapsulation or GRE encapsulation associated with the IPSec Child SA and indicating the type of data that is being transmitted (e.g., non-IP data that comprises raw application data). In this manner, an loT device is able to securely transmit to the 3GPP network IP data/non-IP data/raw application data over an unsecure non 3GPP access network such as Wireless Local Area Network. Methods and apparatus describing the NAS signalling and the PDU session as each using their respective IPSec SA are provided. Similarly, methods and apparatus describing the NAS signalling and the PDU sessions sharing a common IPSec SA are provided. GRE encapsulation of the data within the ESP frame is described for both NAS signalling and PDU session in the case of multiple IPSec/Child SAs or common IPSec SA. Similarly, methods and apparatus are provided for the N3IWF which provides for the UE secure access to the network.

摘要： A method of determining in an IP multimedia subsystem, IMS, network which radio access type, RAT, should be used to route a terminating session directed towards a user equipment, UE. The HSS receives a terminating access domain selection, T- ADS, query from an application server, AS, of the IMS network, the T-ADS query relating to the terminating session and identifying the UE; and determines whether a packet data network gateway, PDN-GW, is registered for the UE. In the case where a PDN-GW is registered, the HSS sends a RAT request towards the PDN-GW, the RAT request identifying the UE and requesting a RAT used by the UE to connect to the IMS network. The PDN-GW determines the RAT and sends the result towards the HSS, which sends a T-ADS response to the AS indicating the RAT. In the case where a PDN-GW is not registered, the HSS sends a T-ADS response to the AS indicating that the RAT is a circuit switched RAT. Apparatus for implementing the method are also provided.

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 ( 3 GPP) Interworking Function (14, N 3 IWF) enabling a wireless communication device (10) to attach to a core network (100) over non- 3 GPP 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- 3 GPP access to the core network (100), to a target AMF (21) which is to serve the wireless communication device (10) over 3 GPP 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： A method performed by a wireless device (110) for enabling reflective Quality-of-Service (QoS) to a bi-directional communications flow (130) in a wireless communications network (100) is provided. The wireless device (121) receives a downlink (DL) data packet of the bi-directional communications flow (130) indicating that reflective QoS is to be applied. The wireless device (121) then determines, based on the type of the bi-directional communications flow (130), that a first reflective QoS rule for filtering Uplink (UL) data packets of the bi-directional communications flow (130) cannot be derived based on control information comprised in the DL data packet. The wireless device (121) further obtains, based on the control information comprised in the DL data packet and the type of the bi-directional communications flow (130), a second reflective QoS rule for filtering UL data packets such that the control information comprised in an UL data packet is at least partly different from the control information comprised in the DL data packet. A wireless device (121) for enabling reflective Quality-of-Service (QoS) to a bi- directional communications flow (130) in a wireless communications network (100) is also provided.
