Abstract
A user has a plurality of user identities, e.g., a Google ID, an IMS ID, a PBX phone number, a Lync ID, etc., corresponding to different domains and/or different autonomous systems. A presence aggregation interworking function (PAIF) device aggregates presence state information corresponding to the same user and different non-Lync IDs, formats the aggregated information into a Lync compatible format, and communicates the aggregated formatted presence state information to a Lync Presence server. The Lync Presence server may, and sometimes does, further aggregates the aggregated presence state information received from the PAIF, corresponding to the user, with presence state information from a device using a Lync ID, corresponding to the same user. The Lync presence server distributes the aggregated presence state information to other devices, which have expressed an interest in receiving presence state information corresponding to the user.
