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

1-30. -30. (canceled)

31. 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;

establishing a two-way wireless communication link with the second system;

communicating a request to the second system over the two-way wireless communication link for the second system to communicate to the first system a view of a document presently being displayed by the second system and not by the first system;

receiving, from the second system over the two-way wireless communication link, a view of the document presently being displayed by the second system;

displaying the received view of the document on a display device of the first system while a view of the document is presently being displayed by the second system; and

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

32. The method of claim 31, 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.

33. The method of claim 31, comprising passing editing privileges for the document to a third system to enable the third system to edit the document.

34. The method of claim 31, comprising editing the document presently being displayed by the second system without receiving original document data from the second system.

35. The method of claim 31, comprising communicating document editing information to the second system to cause the second system to edit the document.

36. The method of claim 31, comprising communicating view modification information to the second system to change the view of the document presently being displayed by the second system.

37. The method of claim 31, comprising receiving an unsolicited view of a document presently being displayed by the second system.

38. The method of claim 31, where the two-way wireless communication link comprises a direct communication link between the first and second systems with no intervening devices.

39. The method of claim 31, comprising receiving document editing information from a user of the first system for editing the document presently being displayed by the second system, and communicating the received editing information to the second system.

40. The method of claim 31, comprising initializing a secure wireless communication link with the second system for communication of document editing information.

41. The method of claim 31, wherein said receiving a view of the document comprises receiving the view of the document modified in accordance with document editing information provided to the second system by the first system.

42. A system for use in a first system for sharing a view with a second system in a wireless communication network, the system comprising:

at least one module operable to, at least;

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

communicate a request to the second system over the two-way wireless communication link for the second system to communicate to the first system a view of a document presently being displayed by the second system and not by the first system;

receive, from the second system over the two-way wireless communication link, a view of the document presently being displayed by the second system;

display the received view of the document on a display device of the first system while a view of the document is presently being displayed by the second system; and

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

43. The system of claim 42, wherein said at least one module comprises a view-sharing sub-module.

44. The system of claim 42, where 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.

45. The system of claim 42, wherein the at least one module is operable to pass editing privileges for the document to a third system to enable the third system to edit the document.

46. The system of claim 42, wherein the at least one module is operable to edit the document presently being displayed by the second system without receiving original document data from the second system.

47. The system of claim 42, wherein the at least one module is operable to communicate document editing information to the second system to cause the second system to edit the document.

48. The system of claim 42, wherein the at least one module is operable to communicate view modification information to the second system to change the view of the document presently being displayed by the second system.

49. The system of claim 42, wherein the at least one module is operable to receive an unsolicited view of a document presently being displayed by the second system.

50. The system of claim 42, where the two-way wireless communication link comprises a direct communication link between the first and second systems with no intervening devices.

51. The system of claim 42, wherein the at least one module is operable to receive document editing information from a user of the first system for editing the document presently being displayed by the second system, and communicate the received editing information to the second system.

52. The system of claim 42, wherein the at least one module is operable to initialize a secure wireless communication link with the second system for communication of document editing information.

53. The system of claim 42, wherein said at least one module is operable to receive the view of the document by, at least in part, operating to receive the view of the document modified in accordance with document editing information provided to the second system by the first system.
