Reauthorization of network sessions based on subscription notifications
The patent US12074919B1 outlines a method and system for managing notifications related to context data associated with registered sessions in a network environment, particularly for user equipment (UE). The method involves receiving a subscription request for notifications tied to context data of a registered session, which is governed by a reauthorization timer. Upon the expiration of this timer, the network device is prompted to issue a reauthorization request for the session. If the session is found to be inactive, the method includes provisions for receiving a status communication that indicates this inactivity, leading to the removal of the associated context data from the network device's resources.
The patent further specifies the types of network devices that can implement this method, including unified data management (UDM) and unified data repository (UDR) devices, as well as various functional components such as access and mobility management function (AMF) devices and session management function (SMF) devices. Additionally, the method allows for the status communication to be formatted in a JavaScript Object Notation (JSON) payload, which includes attributes indicating the session's status. The claims also encompass non-transitory computer-readable media that store instructions for executing the described processes, ensuring that the network device can effectively manage session reauthorization and context data removal based on real-time status updates.
