Abstract

Telephonic and other endpoints often make presence information of other users available on the endpoint. Systems whereby every user sends a notification to every other user quickly becomes resource intensive. Providing presence information only to users subscribed to the presence of other users helps; but, maintaining such subscriptions is often overlooked. Providing automatic subscriptions based upon a triggering event allows presence information to be provided to associated users. The presence information may be time limited to allow for an appropriate amount of presence information to be provided for a duration most likely determined to be relevant. Upon expiration of the subscription, the utilized resources are released without requiring any human intervention.

First claim

What is claimed is:

1 . A system, comprising:
a presence server; an input interface of the presence server configured to receive a triggering event from a triggering device; wherein the triggering device notifies the presence server, via the input interface, of a triggering event associating the first user with the second user; wherein the presence server, in response to the triggering event, automatically and without human intervention, subscribes the first user to presence data for the second user; and an output interface of the presence server configured to provide presence information of the second user to a first endpoint associated with the first user while the first user is subscribed to the presence data of the second user.

2 . The system of claim 1 , wherein the presence server unsubscribe the first user to the presence data of the second user upon receiving, via the input interface, a termination event negating the triggering event.

3 . The system of claim 1 , wherein the first endpoint comprises the triggering device.

4 . The system of claim 1 , wherein the subscription is a time limited subscription determined by an event type of the triggering event.

5 . The system of claim 3 , wherein the presence server is further configured to unsubscribe the first user to the presence of the second user upon expiration of the time limited subscription.

6 . The system of claim 3 , wherein the presence server is further configured to extend the time limited subscription upon the first user having a previously existing time limited subscription to the presence of the second user.

7 . The system of claim 1 , wherein the presence server is configured to subscribe the first user to the presence of the second user, comprising a first set of presence data, and in response to the triggering event, the presence server is further configured to subscribe the first user to at least one additional subscription event not enabled by the first set of presence data.

8 . The system of claim 7 , wherein the presence server is further configured to automatically unsubscribe the first user from the at least one additional subscription event not enabled by the first set of presence data, after the predetermined duration of time after the subscription.

9 . The system of claim 1 , wherein the presence server is further configured to subscribe the first user to the presence of the second user upon determining the first user does not have a previously existing subscription to the second user.

10 . The system of claim 1 , wherein the presence server is further configured to, upon receiving the triggering event via the input interface, subscribe the second user to the presence of the first user and wherein the output interface is further configured to provide presence information of the first user to the second endpoint while the second user is subscribed to the presence data of the first user.

11 . A method, comprising:
receiving a triggering event from a triggering device indicating an association between a first user and a second user; in response to the triggering event, automatically and without human intervention, subscribing the first user to presence data for the second user; receiving presence data of the second user from a second endpoint associated with the second user; and determining the first user is presently subscribed to the presence data of the second user, and in response to the determining, outputting the presence data of the second user to a first endpoint associated with the first user.

12 . The method of claim 11 , wherein the presence data for the second user is determined by a presences datum reported by the second endpoint.

13 . The method of claim 11 , wherein subscribing further comprises subscribing the first user to a time limited subscription.

14 . The method of claim 13 , wherein the time limited subscription has a duration determined by an event type of the triggering event.

15 . The method of claim 11 , wherein subscribing comprises maintaining a previously existing subscription to the second user.

16 . The system of claim 15 , wherein the previously existing subscription to the second user comprises blocking the first endpoint from receiving presences information of the second user.

17 . A non-transitory computer-readable medium that when read by a computer causes the computer to perform:
receiving a triggering event from a triggering device indicating an association between a first user and a second user; in response to the triggering event, automatically and without human intervention, subscribing the first user to presence data for the second user; receiving presence data of the second user from a second endpoint associated with the second user; and determining the first user is presently subscribed to the presence data of the second user, and in response to the determining, outputting the presence data of the second user to a first endpoint associated with the first user.

18 . The non-transitory computer-readable medium of claim 17 , wherein the instructions for subscribing further comprise instructions for subscribing the first user to a time limited subscription.

19 . The non-transitory computer-readable medium of claim 18 , wherein the time limited subscription has a duration determined by an event type of the triggering event.

20 . The non-transitory computer-readable medium of claim 11 , wherein the instructions further comprise instructions to subscribe the second user to the presence of the first user in response to the triggering event.
