Abstract

Methods and apparatus for deriving and/or generating, user presence information from communication signals monitored by a SBC or PRI Gateway and aggregating and/or distributing the user presence information. An exemplary method embodiment includes the steps of storing a plurality of user profile records, each of the user profile records mapping contact information for a user to one or more user identifiers corresponding to the user; receiving first signaling information; determining a first user corresponding to the first signaling information by comparing at least a first portion of the information contained in the first signaling information to at least a first portion of the information contained in the plurality of user profiles; and generating presence status information for the first user and communicating the first presence status information to a presence server as presence status information corresponding to a first user identifier, said first user identifier corresponding to said first user.

updating, at the SBC, said first presence information corresponding to the first user identifier of the first user indicating a presence state of said first user; and

communicating said updated first presence information, in the first format, to the presence server.

6. The method of claim 1, wherein said plurality of user profile records includes a user profile record for the first user and said first user profile record includes contact information for said first user and a first user identifier corresponding to said first user, said contact information for said first user and said first user identifier being different.

7. The method of claim 6, wherein said contact information for said first user includes one or more of the following:

a name, a telephone number, an address, an IMS ID, a MS Lync ID, a Skype for business ID.

8. The method of claim 7, wherein said contact information for said first user is mapped to a MS Lync ID or a Skype for business Lync ID corresponding to the first user.

9. The method of claim 6,

wherein said contact information for said first user includes a plurality of different telephone numbers selected from the following group:

a landline number, a mobile number, a home number, a work number, and a Private Branch Exchange (PBX) line number; and

wherein said at least a first portion of information contained in the first signaling messages is a telephone number; and

wherein said method further includes said SBC normalizing said telephone number of said first signaling messages prior to performing said comparing at least a first portion of information contained in the first signaling messages to at least a first portion of the information contained in the plurality of user profiles.

10. Them method of claim 1 further comprising:

prior to communicating said first presence status information to said presence server in the first format, processing the information contained in the first signaling messages to determine said first presence status information to put it in said first format.

11. The method of claim 1 further comprising receiving said first signaling messages at the monitoring device from a PBX, the first signaling messages including one of the following:

call initiation signaling information, call connection signaling information, and call connection termination signaling information.

12. The method of claim 1 further comprising:

determining, at the monitoring device, a second user corresponding to the first signaling messages by comparing at least a second portion of the information contained in the first signaling messages to at least a second portion of the information contained in the plurality of user profiles;

generating, at the monitoring device, first presence status information corresponding to the second user based on said first signaling messages;

communicating, from the monitoring device, the first presence status information corresponding to the second user, in a first format, to the first presence server as presence status information corresponding to a second user identifier, said second user identifier corresponding to said second user.

13. The method of claim 1 further comprising:

routing, by the SBC, the first signaling messages to a plurality of phone numbers based on contact information contained in a user profile record identified as corresponding to the user for whom the received first signaling messages are destined.
