Abstract

Methods and apparatus for aggregating and distributing contact information for a user with multiple user identifiers in a plurality of domains. In one embodiment a set of user identifiers corresponding to a first user includes a first user identifier corresponding to a first domain and a second user identifier corresponding to a second domain. A request is made using the first user identifier for contacts associated in the first domain with the first user identifier and a request is made using the second user identifier, for contacts associated in the second domain with the second user identifier. An aggregated contact list corresponding to the first user is generated from a first contact list received from the first domain and from a second contact list received from the second domain. In some embodiments the aggregated contact list and associated user presence information is distributed to the first and second domains.

wherein said aggregated contact list includes user identifiers identifying users other than the first user, said aggregated contact list including a third user identifier identifying a second user in a third domain and a fourth user identifier identifying said second user in a fourth domain, said second user being different from said first user, the method further comprising;

monitoring activity of the second user across the third and fourth domains by monitoring devices in the third and fourth domains using the third and fourth user identifiers, said monitoring activity of the second user across the third and fourth domains by monitoring devices in the third and fourth domains using the third and fourth user identifiers includes monitoring signals from said devices in the third and fourth domains using the third and fourth user identifiers; and

generating aggregated presence information for the second user based on the monitored user activity across the third and fourth domains.

2. The method of claim 1, further comprising:

distributing said generated aggregated presence information for the second user with said aggregated contact list to one or more devices in said first domain and to one or more devices in said second domain.

3. The method of claim 2,

wherein said presence aggregation interworking apparatus is a Session Border Controller;

wherein said one or more devices in said first domain include a first contact server; and

wherein distributing said generated aggregated presence information for the second user with said aggregated contact list includes transmitting an indicator that said aggregated contact list is an aggregation of contacts.

4. A method of operating a presence aggregation interworking apparatus, comprising:

storing in memory for a first user a first set of user identifiers identifying said first user, said first set of user identifiers including a first user identifier identifying said first user in a first domain and a second user identifier identifying said first user in a second domain;

requesting, using the first user identifier, contacts associated in the first domain with the first user identifier;

requesting, using the second user identifier, contacts associated in the second domain with the second user identifier;

generating an aggregated contact list for said first user from a first contact list received from said first domain and from a second contact list received from said second domain;

distributing said aggregated contact list to one or more devices in said first domain and to one or more devices in said second domain;

wherein said one or more devices in said first domain include a first server;

wherein distributing said aggregated contact list includes transmitting an indicator that said aggregated contact list is an aggregation of contacts;

wherein said aggregated contact list includes user identifiers identifying users other than the first user, said aggregated contact list including a third user identifier identifying a second user in a third domain and a fourth user identifier identifying said second user in a fourth domain, said second user being different from said first user, the method further comprising;

monitoring activity of the second user across the third and fourth domains by monitoring devices in the third and fourth domains using the third and fourth user identifiers; and

generating aggregated presence information for the second user based on the monitored user activity across the third and fourth domains.

5. The method of claim 4 further comprising:

requesting presence information for said third user identifier from at least one of said first and second domains; and

distributing, with said aggregated contact list, presence information for said second user.

6. The method of claim 5, further comprising:

determining, based on said third user identifier, whether information stored in said memory includes additional user identifiers which identify said second user, said additional user identifiers including a fifth user identifier.

7. The method of claim 6, further comprising, when it is determined that said stored information includes additional user identifiers identifying said second user:

requesting presence information for said second user using said fifth user identifier from a domain, said domain from which said presence information is requested for said second user using said fifth user identifier being a domain in which said fifth user identifier identifies said second user and being different from a domain in which said third user identifier identifies said second user.

8. The method of claim 7, further comprising:

aggregating presence information received in response to said requests for presence information for said third and fifth user identifiers with said generated aggregated presence information for the second user based on the monitored user activity across the third and fourth domains, said aggregating producing updated aggregated presence information for said second user.

9. The method of claim 8, wherein said presence information for said second user distributed with said aggregated contact list includes said generated aggregated presence information for said second user.

10. The method of claim 9, wherein said generated aggregated presence information includes real time presence information.

11. A system, comprising:

a presence aggregation interworking apparatus, said presence aggregation interworking apparatus including;

a memory for storing a first set of user identifiers identifying a first user, said first set of user identifiers including a first user identifier identifying said first user in a first domain and a second user identifier identifying said first user in a second domain;

a contact information request module configured to request, using the first user identifier, contacts associated in the first domain with the first user identifier;

said contact information request module further configured to request, using the second user identifier, contacts associated in the second domain with the second user identifier;

a contact list aggregator module configured to generate an aggregated contact list for said first user from a first contact list received from said first domain and from a second contact list received from said second domain, said aggregated contact list including user identifiers identifying users other than the first user, said aggregated contact list including a third user identifier identifying a second user in a third domain and a fourth user identifier identifying said second user in a fourth domain, said second user being different from said first user; and

a processor that controls the presence aggregation interworking apparatus to;

(i) monitor activity of the second user across the third and fourth domains by monitoring devices in the third and fourth domains using the third and fourth user identifiers, and

(ii) generate aggregated presence information for the second user based on the monitored user activity across the third and fourth domains.

12. The system of claim 11 wherein said presence aggregation interworking apparatus, further includes:

a contact list distribution module configured to distribute said aggregated contact list to one or more devices in said first domain and to one or more devices in said second domain.
