Abstract

A method includes receiving, from an external presence server at a proxy presence device, a presence status request for presence information associated with a user device in a home carrier network. The method includes sending the presence status request to an internal presence server in the home carrier network. The method also includes receiving the presence status of the user device and storing the presence status of the user device with a time to live (TTL) in an associated database. The presence status is sent to the external presence server. The method includes receiving at least one subsequent request for the presence status of the user device within a time window of the TTL. The method also includes sending the presence status within the time window of the TTL without sending another presence status request to the internal presence server.

Claims

1. A computer-implemented method comprising:

receiving, from an external presence server at a proxy presence device, a presence status request from a rich communication service (RCS)-enabled client device for first presence information associated with a user device in a home carrier network;

determining, by the proxy presence device, that the first presence information is not stored in an associated database;

generating, by the proxy presence device and based on the determining, an expanded presence status request requesting the first presence information and second presence information associated with the user device with respect to the home carrier network;

sending the expanded presence status request to an internal presence server in the home carrier network;

receiving an expanded presence status of the user device, wherein the expanded presence status includes the first presence information and the second presence information;

storing the expanded presence status of the user device with a time to live (TTL) in the associated database;

sending the first presence information to the external presence server;

receiving multiple subsequent requests from the RCS-enabled client device for a presence status of the user device within a time window of the TTL;

identifying, based on the multiple subsequent requests exceeding a threshold number of requests within the time window, the RCS-enabled client device as being improperly configured; and

notifying the external presence server that the RCS-enabled client device is improperly configured.

2. The computer-implemented method of claim 1, wherein receiving the presence status request further comprises:

receiving a request for rich communication services.

3. The computer-implemented method of claim 1, wherein receiving the presence status request further comprises:

receiving a query whether the user device is voice enabled.

4. The computer-implemented method of claim 1, wherein receiving the presence status request further comprises:

receiving a query whether the home carrier network network supports enhanced services.

5. The computer-implemented method of claim 1, further comprising:

receiving at least one request from a different external presence server than the external presence server.

6. The computer-implemented method of claim 1, further comprising:

retrieving capabilities data for the user device on a configurable interval.

7. The computer-implemented method of claim 1, wherein the proxy presence device is configured to use Extensible Messaging and Presence Protocol (XMPP) to publish and subscribe to the first presence information and the second presence information.

8. The computer-implemented method of claim 1, wherein the first presence information includes whether a subscriber plan associated with the user device covers RCS.

9. The computer-implemented method of claim 8, wherein the second presence information is associated with a video portion of a voice over long term evolution (VOLTE) call.

10. The computer-implemented method of claim 8, wherein the second presence information includes whether the user device includes a camera.

11. The computer-implemented method of claim 1, wherein sending the expanded presence request comprises:

determining a uniform resource locator (URL) associated with the internal presence server; and

sending the expanded presence status request to the internal presence server via the URL.

12. A device, comprising:

a communication interface;

a memory to store a plurality of instructions; and

a processor configured to execute the instructions in the memory to;

receive, via the communication interface from an external presence server, a presence status request from a rich communication service (RCS)-enabled client device for first presence information associated with a user device in a home carrier network;

determine that the first presence information is not stored in an associated database;

generate, based on the determination, an expanded presence status request requesting the first presence information and second presence information associated with the user device with respect to the home carrier network;

send, via the communication interface, the expanded presence status request to an internal presence server in the home carrier network;

receive, via the communication interface, an expanded presence status of the user device, wherein the expanded presence status includes the first presence information and the second presence information;

store the expanded presence status of the user device with a time to live (TTL) in the associated database;

send, via the communication interface, the first presence information to the external presence server;

receive, via the communication interface, multiple subsequent requests from the RCS-enabled client device for a presence status of the user device within a time window of the TTL;

identify, based on the multiple subsequent requests exceeding a threshold number of requests within the time window, the RCS-enabled client device as being improperly configured; and

notify, via the communication interface, the external presence server that the RCS-enabled client device is improperly configured.

13. The device of claim 12, wherein, when receiving the presence status request, the processor is further to:

receive a request for rich communication services.

14. The device of claim 12, wherein when receiving the presence status request, the processor is further to:

receive a query whether the user device is voice enabled.

15. The device of claim 12, wherein when receiving the presence status request, the processor is further to:

receive a query whether the home carrier network supports enhanced services.

16. The device of claim 12, wherein the processor is further to:

receive at least one request from a different external presence server than the external presence server.

17. The device of claim 12, wherein the device is configured to use Extensible Messaging and Presence Protocol (XMPP) to publish and subscribe to the first presence information and the second presence information.

18. A non-transitory computer-readable medium including instructions to be executed by a processor, the instructions including one or more instructions, when executed by the processor, for causing the processor to:

receive, from an external presence server, a presence status request from a rich communication service (RCS)-enabled client device for first presence information associated with a user device in a home carrier network;

determine that the first presence information is not stored in an associated database;

generate, based on the determination, an expanded presence status request requesting the first presence information and second presence information associated with the user device with respect to the home carrier network;

send the expanded presence status request to an internal presence server in the home carrier network, wherein the expanded presence status includes the first presence information and the second presence status information;

receive an expanded presence status of the user device;

store the expanded presence status of the user device with a time to live (TTL) in the associated database;

send the first presence information to the external presence server;

receive multiple subsequent requests for a presence status of the user device within a time window of the TTL;

identify, based on the multiple subsequent requests exceeding a threshold number of requests within the time window, the RCS-enabled client device as being improperly configured; and

notify the external presence server that the RCS-enabled client device is improperly configured.

19. The non-transitory computer-readable medium of claim 18, wherein, when receiving the presence status request, the one or more instructions further includes instructions for causing the processor to:

receive a request for rich communication services.

20. The non-transitory computer-readable medium of claim 18, wherein, when receiving the presence status request, the one or more instructions further includes instructions for causing the processor to:
