Abstract: Methods, apparatus and systems for backward compatible multi-access protocol data unit session (PDU) registration and deregistration are described. One method of digital communication includes establishing, by a session management function operating in a communication network, a PDU session for a wireless device and transmitting, upon successfully establishing the PDU session, a registration request to a network-side function to register a context of a PDU session of the wireless device with the network-side function, wherein the registration request identifies a set of session management functions that includes the session management function.

Abstract: This disclosure relates to mechanisms for effectuating data traffic routing influence in a core network of a communication system by service applications outside of the core network. The mechanism may be implemented for the core network to establish communication sessions within the core network that route data traffic according to the data traffic routing influence requests from application servers. The mechanism may further be implemented for the core network to modify or reconfigure network nodes for an active existing communication session within the core network to effectuate data traffic routing influence request from the application servers.

Abstract: Systems and methods for wireless communications are disclosed herein. In one embodiment, the system and method are configured to receive, by a mobility management function (AMF) from a network function (NF), slice information including at least one of a quality of service (QoS) profile for a slice or a service area of the slice. The AMF can determine that a wireless communication device is authorized to access a slice based on the service area of the slice. The AMF can send the QoS profile comprising a slice-specific aggregate maximum bit rate (AMBR) specific to the slice to the radio access network.
