Abstract: Methods and system for supporting traffic steering through a service function chain, the service function chain comprising at least one data processing function. An aspect of the disclosure provides for a method for steering traffic of a packet data unit (PDU) performed by a session management function. The method includes receiving PCC rules from a policy control function, the PCC rules including information comprising at least one of service function chain information; final delivery indication; and selective traffic steering information and associated parameters. The method further includes configuring at least one user plane function (UPF) according to the information. In some embodiments the configuring the at least one UPF includes instructing a first UPF to detect traffic according to the packet detection rules and route the received packet according to the forwarding action rules.

Abstract: Method and system for performance assurance in a network slice subset instance (NSSI) or a network slice instance (NSI) of a network. The method comprises receiving, at a network management function (OAM) of the network, a trigger indicating a network performance deficiency; based on the trigger, determining, by a data analytics (DAM) function of the OAM (OAM DAM) in coordination with a network analytics function of one of the core network and a radio access network (RAN) , an NSI/NSSI modification; and implementing, by the OAM, a change in at least one of: NSI/NSSI policies, configurations in at least one of core network functions, the RAN and network resources, in accordance with the NSF NSSI modification.

Abstract: The present invention provides methods, apparatuses and systems supporting in-order packet delivery during application relocation or UP (User Plane) path management events such as DNAI (Data Network Access Identifier) changes. In-order packet delivery may be enforced, ensured or supported by using an indication that in-order packet delivery is requested or required for a particular traffic flow of a UE during a user plane path management event. The methods may be performed by apparatuses implementing an application function (AF), a policy control function (PCF), a session management function (SMF), or UP entities such as PDU session anchors, of the communication network, or systems implementing a combination thereof. The SMF may configure UP entities to transmit packets and flow end markers to support in-order packet delivery and provide flow end marker information to the UP entities. The UP entities may signal path changes using flow end markers.

Abstract: The present invention provides methods and apparatuses for service based architecture (SBA) for data analytics management (DAM). Configuration specifications are provided for configuring DAM entities for infrastructure management by infrastructure managers (InfMs), customer service managers (CSMs) for network slice subnet instance (NSSI), network slice instance (NSI) and service instance (SI) management, content and forwarding managers (CFM) for content and content cache management. Also provided are methods and apparatus for data analytics service provisioning regardless of DAM architecture.
