Abstract:
1. A method for providing a user record deletion notification, the method comprising: determining, at a subscriber data management (SDM) node, that a service subscription to an access network is to be terminated, wherein the service subscription is associated with a subscriber user; generating, at the SDM node, a Diameter notification message that includes a deletion notification attribute; sending, by the SDM node, the Diameter notification message via a Sh interface or a Ud interface to an application server associated with the access network; terminating, at the application server, a communication service connection established between the subscriber user and the access network in response to detecting the deletion notification attribute in the Diameter notification message, wherein detecting the deletion notification attribute includes accessing a user profile portion of the Diameter notification message to parse the deletion notification attribute; and deleting, in the SDM node, a user record associated with the service subscription after receiving notification of the connection termination.
