DYNAMIC RESOURCE LIST SUBSCRIPTIONS

摘要

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.

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.
