Abstract: Described are apparatuses, methods, and computer program products for enabling splitting, switching, and steering of access traffic in a system, e.g., a fifth-generation (5G) system. Access and mobility management functions (AMF) of the 5G system forward one or more of the registration requests to unified data management (UDM) functions of the PLMNs. UDM function determines whether evolved packet system (EPS) interworking (IWK) is allowed for respective registration requests based on subscription, deployment, system capabilities, a radio access technology (RAT) of an access path between the UE and the 5G system, etc. UE can include an indication that EPS IWK is requested and/or required in a registration request.

Abstract: There is provided a method for an apparatus for a network function, the apparatus for the network function, and a computer program for the apparatus, that causes the apparatus to: receive an indication that a first user equipment and/or a first user plane function configured to transmit first user traffic is associated with a first replication handling function, the first replication handling function being configurable to coordinate at least one replication-based redundancy mechanism performed on at least part of said first user traffic; determine a first set of replication rules for use by the first replication handling function determining when the at least one replication-based redundancy mechanism is performed on at least part of said first user traffic; and cause the first set of replication rules to be provided to the first replication handling function.

Abstract: There is provided an apparatus comprising means for receiving information about an identification of a network function set associated with at least one packet data network connection. The means is further configured for, in response to receiving an indication that a network function instance of the network function set supporting the at least one packet data network connection is no longer available, transferring the at least one packet data network connection from the network function instance to another network function instance comprised within the network function set.

Abstract: Techniques for accessing a core network via access points and gateway functions are provided. For example, a method comprises: determining one or more candidate gateway functions for accessing the core network via the access point; transmitting, to the one or more candidate gateway functions or to a core network function, a request for use of the one or more gateway functions to access the core network; and receiving, from the gateway function or from the core network function, a request response per candidate gateway function, the request response being configured to indicate whether the access to the core network via the respective gateway function is rejected and, in the case of rejection, to indicate a cause of rejection. The method may be performed by the terminal device (e.g., a user equipment, UE). Corresponding methods that can be performed by a network device are also provided.

Abstract: There is provided an apparatus, method and computer program fora network function, that causes the apparatus to signal, to a replication handling function, a set of replication criteria defining, for one or more session associated with a first user traffic and a second user traffic, when at least one of the first and second user traffic will be transmitted using a replication-based redundancy mechanism, wherein each of the first and second user traffic are associated with a respective quality of service requirement for transmission.

Abstract: Techniques for enforcing packet detection rules within communication systems are provided. A network entity may configure a user plane function to detect whether a domain name system request sent by a user equipment satisfies one or more packet detection rules. The network entity may receive, from a user plane function, a report that a domain name system request sent by the user equipment has been detected as non-compliant with instructions sent to the user equipment. The network entity may cause one or more corrective actions relating to traffic offloading.
