Abstract: Systems and methods are provided for optimizing session continuity management during 5th Generation (5G) and 4G/Long Term Evolution (LTE) interworking. Conventional 4G/LTE and 5G interworking involves session continuity subscription or retrieval operations to obtain the latest mobility data for a user equipment (UE) attempting to attach to a particular communications network. These operations include exchanging various messages can be avoided by determining the existence of an Authentication, Authorization, Accounting (AAA)/evolved Packet Data Network Gateway (ePDG) registration (among other conditions).

Abstract: The systems and method disclosed herein select a customized or default UE SIM profile for a registration with a particular network element in a specific jurisdiction based on the identification of the serving network element (e.g. MME, SGSN, S-CSCF). The default profile may be chosen over a particular subscriber identifier in various jurisdictions and types of networks. To implement the default profile, the subscription server may store a New Radio (NR) as a Secondary Radio Access Technologies (RAT) identifier, or “NR as a Secondary RAT” identifier, and set the value of the identifier as “ALLOW” or “DENY” of the default profile described herein.

Abstract: 5G provides for interworking with the 4G/LTE networks, which provides for mobility of user equipment between the 5G and 4G/LTE networks. Mobility from 5G to 4G/LTE requires deregistering user equipment from the 5G core network (5GC) by communicating a deregistration notification from the Evolved Packet Core (EPC) to the 5GC. Systems and methods disclosed herein provide for an optimized deregistration process through avoidance of redundant deregistration notification traffic injected into the 5G network by utilizing 4G/LTE connectivity information to determine whether or not to inject deregistration notifications into the 5G network.
