Abstract: A communication system includes a user plane function (UPF) configured to receive a domain name system (DNS) query from a user equipment (UE). The DNS query includes a first destination address of a first DNS server. The DNS query is for determining an address of a data server in proximity to the UE. According to the first destination address of the first DNS server, the UPF obtains, from a session management function (SMF), a second destination address of a second DNS server for providing the address of the data server. The SMF is configured to provide, to the UPF, the second destination address of a second DNS server.

Abstract: Methods by which User Plane (UP) management information is exchanged between an Application Function (AF) supporting one or more applications and a Slice Management Function (SMF) configured to manage traffic flows in a given slice of the network. The exchange of UP management information may be initiated from either the AF or the SMF. In the case of AF-initiated information exchange, the UP management information provided by the AF may comprise traffic requirements of applications supported by the AF. In the case of SMF-initiated information exchange, the UP management information provided by the SM may comprise operator policy information or events, and the AF may respond with information of traffic requirements of applications supported by the AF.

Abstract: The present invention provides methods and apparatus for notifying Quality of Service (QoS) information to User Equipment (UE), Users, and Application server. Embodiments of the present invention may analyze the network QoS and/or statistics of QoS parameters using one or more functions such as Network Data Analytics Function (NWDAF). Embodiments may also provide control plane (CP) functions which may send the QoS information to the UE depending on the UE subscription, application and/or network slice.

Abstract: A network function and a method for associating a UE of a UE group to a PDU session with in a CN. The NF establishes a shared PDU session for the UE group before all of the UEs in the UE group register with the CN and binds a UE that has not yet registered with the CN to the shared PDU session when the UE registers with the CN, provided the UE will share at least one of a UL UP connection and a DL UP connection associated with the shared PDU session. The NF may be an SMF.

Abstract: Aspects of the disclosure provide a system and method used for allowing a path selection or reselection (hereby (re)selection). In some embodiments data packets for a session between a UE and an application system (AS) can utilize a pre-established user plane path between the AS and an access node (AN) which serves the UE. This can allow for faster session set-up times as a new user plane (UP) path need not be established for every new session if existing UP paths can be utilized. Some embodiments allow an application aware (re)selection of the user plane.

Abstract: There is provided methods, systems and apparatuses for management of network functions. In some embodiments, an apparatus includes a processor and a non-transient memory for storing instructions that when executed by the processor cause the apparatus to be configured to perform a method including steps as follows. The apparatus is configured to perform steps including sending, towards a source network exposure function (S-NEF) associated with a user equipment (UE), an event notification and obtaining, information on a target network exposure function (T-NEF) to be associated with the UE, and sending towards the S-NEF an event subscription update notification indicative of a change of destination for subsequent event notifications. The apparatus is further configured to perform steps including receiving, from the S-NEF, an event subscription update notification acknowledgement indicative of acceptance of the change and sending, towards the T-NEF, the subsequent event notifications.
