METHODS AND SYSTEMS FOR AGGREGATING PRESENCE INFORMATION TO PROVIDE A SIMPLIFIED UNIFIED PRESENCE

摘要

Methods and systems for providing simplified presence for a user are described. The user has a plurality of associated communication devices registered with a communications server, and each communication device enables at least one communication service class. The server has a user data entry associating the user with each of the plurality of communication devices. To hide the details of the user-associated devices from third parties, a virtual device is defined and associated with the user. Presence information received at the server from the various devices is aggregated together to create aggregated presence information that indicates at least the service classes available from the user-associated devices based on the received presence information. A virtual device presence document is generated containing the aggregated presence information and is provided to a presence server as presence information associated with the user.
