Abstract

A network-based messaging system comprises multiple agents to communicate messages between multiple users in real time using, for example, an XML document synchronization model. Each agent has properties defined in XML and can subscribe to properties of other agents. Each agent can notify other agents which subscribe to it of changes to its properties. The agents communicate using an XML or alternative extensible data interchange protocol. The agents include device agents to represent each of multiple user devices, which may include computers on a wireline network and mobile devices on a wireless network. The agents also include persona agents to represent each user. The persona agents collect information about the properties of other agents and publish the information to other, subscribing agents. Each persona agent comprises properties to maintain state information for each device used by the corresponding user. Most of the agents reside in a centralized agent system.

Claims

1. A method comprising:

creating a plurality of agents to communicate messages for a plurality of users by using a data synchronization model, the plurality of agents including a plurality of device agents, one for each of a plurality of user devices used by the plurality of users, and a plurality of persona agents, one for each of the users, each agent having one or more properties and having the ability to subscribe to properties of other agents of the plurality of agents; and

using the persona agents to collect information about the properties of other agents, including the device agents, and to publish the collected information to one or more other agents which subscribe to the corresponding properties.

2. A method as recited in claim 1, wherein the device agents communicate with each other through one or more of the persona agents.

3. A method as recited in claim 1, wherein each of the plurality of agents has a set of properties to maintain state information.

4. A method as recited in claim 3, wherein the plurality of user devices comprise a wireless device, the wireless device comprising an embedded client application configured to receive and interpret extensible markup language data representing changes to said state information.

5. A method as recited in claim 1, wherein at least one of the device agents represents a wireless user device that has an intermittent connection to the other user devices, wherein said device agent has a set of subscriptions and maintains state information for the set of subscriptions, and wherein said device agent communicates with a corresponding one of the persona agents to update said state information.

6. A method as recited in claim 5, wherein said corresponding one of the persona agents automatically publishes to said device agent state information to which the device agent has subscribed, when the user device represented by said device agent establishes the connection.

7. A method as recited in claim 5, wherein the state information comprises device presence or location information.

8. A method as recited in claim 1, wherein the plurality of agents comprises a chat agent to represent a chat session.

9. A method as recited in claim 1, wherein the plurality of user devices comprises a computer coupled to a wireline network and a mobile device operating on a wireless network, the computer and the mobile device each represented by a separate one of the agents.

10. A method as recited in claim 1, wherein the agents communicate with each other using an extensible data interchange protocol.

11. A method as recited in claim 10, wherein the agents communicate with each other using an extensible markup language (XML) based protocol.

12. A method as recited in claim 1, wherein a change to a property of one of the agents is automatically published to an agent which has subscribed to the property of said one of the agents.

13. A method as recited in claim 1, wherein at least some of the agents can set properties of other ones of the agents.

14. A method as recited in claim 1, wherein for at least one of the agents, a user associated with said agent can control which agents may subscribe to properties of said agent.

15. A method as recited in claim 1, wherein for at least one of the agents, a user associated with said agent can specify the properties of said agent to which other agents may subscribe.

16. A method as recited in claim 15, wherein the user associated with said agent can specify the properties of said agent to which other agents may subscribe on a per-subscriber basis.

17. A method as recited in claim 1, wherein the plurality of agents further comprises an interoperability agent to connect the messaging system with another messaging system, and wherein the interoperability agent converts between an extensible data interchange protocol used by the plurality of agents and another protocol used by said other messaging system.

18. A method as recited in claim 17, wherein said method is performed as part of execution of a user-to-user messaging application.

19. A method as recited in claim 18, wherein the user-to-user messaging application is an Instant Messaging (IM) application.

20. A method as recited in claim 1, wherein said method is performed as part of execution of a content distribution application.

21. A method as recited in claim 1, wherein said method is performed as part of execution of a game application.

22. A method as recited in claim 1, wherein said method is performed as part of execution of a user collaboration application.

23. A method as recited in claim 1, wherein said method is performed as part of execution of a call setup application.

24. A method as recited in claim 1, wherein said method is performed as part of execution of a provisioning application.

25. A method as recited in claim 1, wherein said method is performed as part of execution of an alerting/notification application.

26. An apparatus comprising:

means for creating a plurality of agents to communicate messages for a plurality of users by using a data synchronization model, the plurality of agents including a plurality of device agents, one for each of a plurality of user devices used by the plurality of users, and a plurality of persona agents, one for each of the users, each agent having one or more properties and having the ability to subscribe to properties of other agents of the plurality of agents; and

means for using the persona agents to collect information about the properties of other agents, including the device agents, and publish the collected information to one or more other agents which subscribe to the corresponding properties.

27. A user-to-user messaging system comprising:

a processor; and

a storage facility coupled to the processor and storing code which configures the processor to create a plurality of agents to communicate user-to-user messages between a plurality of users in real time by using a data synchronization model, each agent having one or more properties and having the ability to subscribe to properties of other agents of the plurality of agents, the plurality of agents including

a plurality of device agents, one for each of a plurality of user devices used by the plurality of users;

a plurality of persona agents, one for each of the users, to collect information about the properties of other agents, including the device agents, and publish the collected information to one or more other agents which subscribe to the corresponding properties.

28. A messaging system comprising:

a plurality of agents to communicate messages between a plurality of users in real time by using an extensible data interchange protocol to implement a document synchronization model, each agent having one or more properties and having the ability to subscribe to properties of other agents of the plurality of agents, wherein the plurality of agents communicate using said extensible data interchange protocol, the plurality of agents including

a plurality of device agents, one for each of a plurality of user devices used by the plurality of users, the plurality of user devices including a computer coupled to a wireline network and a mobile device operating on a wireless network; and
