Original Abstract Submitted

Technology is disclosed herein for operating a wireless network including deregistering a user device from the network. In an implementation, a first network element deregisters the user device from the wireless network. The first network element determines a cause of the deregistration from among a plurality of possible causes and generates a notification message indicating the cause of the deregistration. The first network element communicates the notification message to a second network element which purges subscriber data from a data repository of the network and updates a subscriber profile of the user device with the cause of the deregistration. In an implementation, the first network element is an Access and Mobility Management function (AMF), the second network element is a Unified Data Management function (UDM), and the data repository is a Unified Data Repository (UDR) of the network.
