Abstract

A personal mobility system determines a terminal address corresponding to a called user based upon a personal identifier of the called user. The personal mobility system operates in conjunction with a plurality of heterogeneous networks to provide the terminal address corresponding to the called user, independent of the particular network within which the called user currently operates. The personal mobility system includes a personal mobility user application and a personal mobility server application. The personal mobility user application receives a request from a calling user, the request including the personal identifier of a called user. The personal mobility server application couples to the personal mobility user application and includes a plurality of user records. Each user record is respective to a user and is indexed by a respective personal identifier. Further, each user record includes a plurality of terminal records with each of the terminal records including a respective terminal address. The personal mobility server application accesses the user record for the called user based upon the personal identifier, selects a terminal record of the plurality of terminal records based upon the personal identifier, and returns a respective terminal address to the personal mobility user application. The user record may also include a network usage profile and a user profile for the user which are both employed in selecting the terminal identifier.

Claims

1. A personal mobility system for connecting a calling user to a called user based upon a personal identifier of the called user, the personal mobility system comprising:

a personal mobility user application resident on a calling user'"'"'s terminal that receives a request from a calling user, the request including the personal identifier of a called user;

a personal mobility server coupled to the Internet, the personal mobility server storing a plurality of user records;

each user record being respective to a user and indexed by a respective personal identifier, and each user record including a plurality of terminal records, each of the terminal records including a respective terminal address;

the personal mobility user application sending a service query to the personal mobility server via a communication path that includes the Internet, the service query including the personal identifier of the called user;

the personal mobility server accessing the user record for the called user based upon the personal identifier, selecting a terminal record of the plurality of terminal records and returning a respective terminal address to the personal mobility user application via a communication path that includes the Internet; and

the personal mobility user application causing the calling user'"'"'s terminal to access a called user'"'"'s terminal via a network path selected by the calling user'"'"'s terminal based upon the respective terminal address.

2. The personal mobility system of claim 1, wherein:

the user record further includes a network usage profile for the user; and

the personal mobility server selecting the terminal record of the plurality of terminal records based upon the network usage profile of the called user.

3. The personal mobility system of claim 1, wherein:

the user record further includes a historical usage table for the user; and

the personal mobility server uses the historical usage table to create the network usage profile for the user.

4. The personal mobility system of claim 1, wherein:

the service query includes an indication of the type of communication to be established between the calling party'"'"'s terminal and the called party'"'"'s terminal;

the personal mobility server selects the respective terminal address based upon the type of communication to be established between the calling party'"'"'s terminal and the called party'"'"'s terminal; and

the type of communication is selected from the group including voice communications, video communications, and data communications.

5. The personal mobility system of claim 1, wherein:

when required, the network path includes a plurality of segments, the plurality of segments including a circuit switched segment and a packet switched segment.

6. The personal mobility system of claim 1, wherein:

the user record further includes a user profile for the user; and

the personal mobility server selecting the terminal record of the plurality of terminal records based upon the user profile of the called user.

7. The personal mobility system of claim 1, wherein:

prior to sending the service query, the personal mobility user application investigates recent operations based upon the personal identifier; and

if the personal mobility user application has recently accessed a called user corresponding to the personal identifier, the personal mobility user application retrieves a respective terminal address and accesses the called user'"'"'s terminal corresponding to the respective terminal address.

8. The personal mobility system of claim 1, wherein the personal mobility server comprises:

a personal mobility application server that interfaces with the personal mobility user application; and

a personal mobility database server coupled to the personal mobility application server that stores the user records.

9. The personal mobility system of claim 8, wherein:

the personal mobility application server includes a plurality of intercoupled server computers; and

the personal mobility application server includes a plurality of intercoupled databases.

10. The personal mobility system of claim 1, wherein the personal mobility system serves a plurality of heterogeneous networks selected from the group consisting of Internet Protocol networks, Public Switched Telephone Networks, cellular wireless networks, wireless satellite networks, local area networks and wide area networks.

20. The method of claim 1, wherein a plurality of heterogeneous networks selected from the group consisting of Internet Protocol networks, Public Switched Telephone Networks, cellular wireless networks, wireless satellite networks, local area networks and wide area networks are serviced.

11. A method of completing a communication from a calling user to a called user, the method comprising:

storing a plurality of user records on a personal mobility server, each user record respective to a user and indexed by a respective personal identifier, and each user record including a plurality of terminal records, each of the terminal records including a respective terminal address;

receiving a request from a calling user at a calling user'"'"'s terminal, the request including the personal identifier of a called user;

sending a service query from the calling user'"'"'s terminal to the personal mobility server via a communication path that includes the Internet, the request including the personal identifier of a called user;

accessing by the personal mobility server the plurality of user records to identify a user record corresponding to the personal identifier;

of a plurality of terminal records associated with the identified user record, selecting by the personal mobility server a terminal record of the plurality of terminal records;

returning a respective terminal address to the calling user at the calling user'"'"'s terminal; and

accessing, by the calling user'"'"'s terminal, the called user'"'"'s terminal via a network path selected by the calling user'"'"'s terminal based upon the respective terminal address.

12. The method of claim 11, further comprising:

storing a network usage profile of the user in a respective user record; and

selecting the terminal record of the plurality of terminal records based upon the network usage profile of the called user.

13. The method of claim 11, further comprising:

storing a historical usage table for the user in a respective user record; and

using the historical usage table to create the network usage profile for the user.

14. The method of claim 13, wherein the historical usage table is generated over time based upon the user'"'"'s usage of the terminals identified in a respective user record.

15. The method of claim 11, wherein:

when required the network path includes a plurality of segments, the plurality of segments including a circuit switched segment and a packet switched segment.

16. The method of claim 11, further comprising:
