Methods, systems, and computer readable media for providing a user record deletion notification
View Patent ↗Methods, systems, and computer readable media for providing a user record deletion notification are disclosed. In one example, the method comprises 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 notification message that includes a deletion notification attribute, and sending the Diameter notification message to an application server associated with the access network. The method further includes 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 notification message and deleting, in the SDM node, a user record associated with the service subscription after receiving notification of the connection termination.
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.
2. The method of claim 1 wherein the SDM node includes a subscriber profile repository (SPR) node.
3. The method of claim 1 wherein the application server includes a policy control and charging rules function (PCRF) node, a telephony application server (TAS), or a short message service center (SMSC) node.
4. The method of claim 1 wherein the Diameter notification message includes a Diameter Push Notifications Request (PNR) message or an Extensible Markup Language (XML) Notify Request message.
5. The method of claim 1 wherein the Diameter notification message includes a message that is sent via an interface that supports change notification messaging and does not support deletion notification messaging.
6. The method of claim 1 wherein the deletion notification attribute includes a lifetime parameter set to a zero value.
7. The method of claim 1 wherein the deletion notification attribute includes an attribute value that indicates a request for the termination of the service subscription associated with the subscriber user.
8. The method of claim 1 wherein determining that the service subscription to the access network is terminated includes receiving, at the SDM node, a delete user record command message from a subscriber provisioning system node in the access network.
9. The method of claim 1 wherein the access network includes a 3G wireless network, a 4G wireless network, a Long Term Evolution (LTE) network, a cable fixed network, or a fiber optic service fixed network.
10. A system for provisioning a Diameter binding repository, the system comprising:
a subscriber data management (SDM) node configured to determine that a service subscription to an access network is to be terminated, wherein the service subscription is associated with a subscriber user, generate a Diameter notification message that includes a deletion notification attribute, and send the Diameter notification message, and delete a user record associated with the service subscription in response to receiving a notification of a connection termination, wherein the SDM node is further configured to send the Diameter notification message via a Sh interface or a Ud interface; and
an application server configured to receive the Diameter notification message, detect the deletion notification attribute in the Diameter notification message, delete a communication service connection established between the subscriber user and the access network, and provide the notification of the connection termination, wherein the application server is further configured to access a user profile portion of the Diameter notification message to parse the deletion notification attribute.
11. The system of claim 10 wherein the SDM node includes a subscriber profile repository (SPR) node.
12. The system of claim 10 wherein the application server includes a policy control and charging rules function (PCRF) node, a telephony application server (TAS), or a short message service center (SMSC) node.
13. The system of claim 10 wherein the Diameter notification message includes a Diameter Push Notifications Request (PNR) message or an Extensible Markup Language (XML) Notify Request message.
14. The system of claim 10 wherein the Diameter notification message includes a message that is sent via an interface that supports change notification messaging and does not support deletion notification messaging.
15. The system of claim 10 wherein the deletion notification attribute includes a lifetime parameter set to a zero value.
16. The system of claim 10 wherein the deletion notification attribute includes an attribute value that indicates a request for the termination of the service subscription associated with the subscriber user.
17. The system of claim 10 wherein the SDM node is further configured to receive a delete user record command message from a subscriber provisioning system node in the access network.
18. The system of claim 10 wherein the access network includes a 3G wireless network, a 4G wireless network, a Long Term Evolution (LTE) network, a cable fixed network, or a fiber optic service fixed network.
19. A non-transitory computer readable medium comprising computer executable instructions embodied in a computer readable medium that when executed by a processor of a computer control the computer to perform steps 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.
