Abstract

Disclosed are a network-based device, method and computer-readable medium for operating an IP Multimedia Subsystem (IMS) to provide registration review. The method embodiment includes tracking and storing all current registrations for each user in an IMS system, receiving a request from a user for a status of the user'"'"'s current registrations and presenting, in response to the request, the current status of current registrations for the user.

Claims

1. A method comprising:

receiving a registration event notification, the registration event notification being generated by a time-based trigger, wherein the time-based trigger is activated when a first device is not used for a defined period of time;

after receiving the registration even notification, sending an alert to a second device regarding the registration event notification; and

routing a communication intended for the first device to an alternative device based on a classification of an originator of the communication, wherein the first device and the alternative device utilize contact addresses at which a public user identity is registered and wherein a same serving call/session control function is used and established until a last device registered with the public user identity has been de-registered from all contact addresses.

2. The method of claim 1, wherein the time-based trigger is tied to a specific location.

3. The method of claim 1, further comprising identifying a plurality of devices associated with a public user identity of the user.

4. The method of claim 1, wherein the registration event notification indicates a de-registration of the first device.

5. The method of claim 1, further comprising:

receiving an instruction from the user to take an action relative to a current registration of the alternative device; and

taking the action to modify an aspect of the current registration associated with the alternative device.

6. The method of claim 1, wherein the time-based trigger further is activated at a pre-defined time of day.

7. A system comprising:

a processor; and

a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising;

receiving a registration event notification, the registration event notification being generated by a time-based trigger, wherein the time-based trigger is activated when a first device is not used for a defined period of time;

after receiving the registration even notification, sending an alert to a second device regarding the registration event notification; and

routing a communication intended for the first device to an alternative device based on a classification of an originator of the communication, wherein the first device and the alternative device utilize contact addresses at which a public user identity is registered and wherein a same serving call/session control function is used and established until a last device registered with the public user identity has been de-registered from all contact addresses.

8. The system of claim 7, wherein the time-based trigger is tied to a specific location.

9. The system of claim 7, the computer-readable storage medium having additional instructions stored which, when executed by the processor, cause the processor to perform operations comprising identifying a plurality of devices associated with a public user identity of the user.

10. The system of claim 7, wherein the registration event notification indicates a de-registration of the first device.

11. The system of claim 7, the computer-readable storage medium having additional instructions stored which, when executed by the processor, cause the processor to perform operations comprising:

receiving an instruction from the user to take an action relative to a current registration of the alternative device; and

taking the action to modify an aspect of the current registration associated with the alternative device.

12. The system of claim 7, wherein the time-based trigger further is activated at a pre-defined time of day.

13. A computer-readable storage device having instructions stored which, when executed by a computing device, cause the computing device to perform operations comprising:

receiving a registration event notification, the registration event notification being generated by a time-based trigger, wherein the time-based trigger is activated when a first device is not used for a defined period of time;

after receiving the registration even notification, sending an alert to a second device regarding the registration event notification; and

routing a communication intended for the first device to an alternative device based on a classification of an originator of the communication wherein the first device and the alternative device utilize contact addresses at which a public user identity is registered and wherein a same serving call/session control function is used and established until a last device registered with the public user identity has been de-registered from all contact addresses.

14. The computer-readable storage device of claim 13, wherein the time-based trigger is tied to a specific location.

15. The computer-readable storage device of claim 13, having additional instructions stored which, when executed by the computing device, cause the computing device to perform operations comprising identifying a plurality of devices associated with a public user identity of the user.

16. The computer-readable storage device of claim 13, wherein the registration event notification indicates a de-registration of the first device.

17. The computer-readable storage device of claim 13, having additional instructions stored which, when executed by the computing device, cause the computing device to perform operations comprising:

receiving an instruction from the user to take an action relative to a current registration of the alternative device; and

taking the action to modify an aspect of the current registration associated with the alternative device.
