Abstract

A system and method for sharing a view between systems in a dynamic wireless communication network. Various aspects of the present invention may comprise a first system communicating information of a view to a display resource of the first system. The first system may establish a two-way wireless communication link between the first system and a second system in the dynamic wireless communication network. The second system may, for example, communicate a request to the first system for the first system to share a view with the second system. The first system may, for example, receive such a request and respond to such a request by communicating information of a view to the second system. The second system may then communicate information of the view to a display resource of the second system. Various aspects may comprise the first and second systems communicating view modification information between the systems.

Claims

1. In a first system, a method for sharing a view with a second system in a wireless communication network, the method comprising:

in the first system;

communicating a view of a document to a display resource of the first system;

displaying the view of the document on the display resource of the first system;

communicating a view of the document to a third system for display by the third system;

establishing a two-way wireless communication link between the first system and the second system;

determining whether the second system is authorized to receive a view of the displayed document;

providing, via a user interface device of the first system, a list of systems in the wireless communication network from which a user of the first system may select one or more systems with which to share a view of the document;

receiving, via a user interface device of the first system, one or more requests from the user of the first system for the first system to communicate a view of the displayed document to the second system and to provide the second system editing capability for the document, wherein said one or more requests comprise a user selection of the second system from the list of systems; and

while displaying the view of the document on the display resource of the first system, if it is determined that the second system is authorized to receive a view of the displayed document, and in response to the received one or more requests;

communicating a view of the document to the second system over the two-way wireless communication link; and

communicating, to the second system over the two-way wireless communication link, an indication that the second system has editing privileges for the document, where said editing privileges comprise the capability to transfer said editing privileges to the third system.

2. The method of claim 1, wherein determining whether the second system is authorized to receive a view of the displayed document comprises analyzing a list of authorized systems.

3. The method of claim 1, comprising, in the first system, initializing a secure wireless communication link between the first system and the second system for communication of document editing information.

4. The method of claim 1, comprising, in the first system, transmitting a message to the second system to inquire whether a user of the second system desires the first system to communicate a view of the displayed document to the second system.

5. The method of claim 1, wherein determining whether the second system is authorized to receive a view of the displayed document comprises communicating authentication information with the second system.

6. The method of claim 1, wherein communicating a view of the document to the second system comprises communicating the view of the document to the second system without receiving a request for a view of the document from the second system.

7. The method of claim 1, comprising, in the first system, receiving document editing information from the second system, and editing the document in accordance with the received document editing information.

8. The method of claim 1, wherein the indication comprises a token that may alternatively be passed by the second system back to the first system or passed to a system other than the first and second systems.

9. A system for use in a first system for sharing a view with a second system in a wireless communication network, the first system having at least a video display resource and a communication module, the system comprising:

at least one module that operates to, at least;

communicate a view of a document to the video display resource;

utilize the communication module to communicate a view of the document to a third system for display by the third system;

utilize the communication module to establish a two-way wireless communication link with the second system;

determine whether the second system is authorized to receive a view of the displayed document;

provide, via a user interface device of the first system, a list of systems in the wireless communication network from which a user of the first system may select one or more systems with which to share a view of the document;

receive, via a user interface device of the first system, one or more requests from the user of the first system for the first system to communicate a view of the document to the second system and to provide the second system editing capability for the document, where said one or more requests comprise a user selection of the second system from the list of systems; and

while communicating the view of the document to the video display resource, if it is determined that the second system is authorized to receive a view of the displayed document, and in response to the received request, utilize the communication module to;

communicate a view of the document to the second system over the two-way wireless communication link; and

communicate, to the second system over the two-way wireless communication link, an indication that the second system has editing privileges for the document, where said editing privileges comprise the capability to transfer said editing privileges to the third system.

10. The system of claim 9, wherein the at least one module comprises a view-sharing sub-module.

11. The system of claim 9, wherein the at least one module operates to determine whether the second system is authorized to receive a view of the displayed document by, at least in part, operating to analyze a list of authorized systems.

12. The system of claim 9, wherein the at least one module operates to utilize a secure communication module of the first system to establish a secure wireless communication link between the first system and the second system for communication of document editing information.

13. The system of claim 9, wherein the at least one module operates to determine whether the second system is authorized to receive a view of the displayed document by, at least in part, operating to utilize the communication module to communicate authentication information with the second system.

14. The system of claim 9, wherein the at least one module operates to utilize the communication module to communicate the view of the document to the second system without receiving a request for a view of the document from the second system.

15. The system of claim 9, wherein the at least one module operates to:

utilize the communication module to receive document editing information from the second system; and

edit the document in accordance with the received document editing information.

16. The system of claim 9, wherein the indication comprises a token that may alternatively be passed by the second system back to the first system or passed to a system other than the first and second systems.
