Method and system for improving the efficiency of state information transfer over a wireless communications network
First Claim
1. A system for managing state information related to an interactive application to accommodate one or more users participating in an interactive application session, wherein the state information comprises local state information specific to each of the one or more user'"'"'s unique view of the interactive application and global state information, the system comprising:
- a telecommunications network;
an application server in communication with said telecommunications network for managing the global state information relative to all of the users participating in the interactive application session; and
at least one mobile client device in communication with said application server over said telecommunications network for managing the local state information for each of the one or more users.

Abstract
The present invention is directed to a system and method for managing state information related to an interactive application to accommodate one or more users participating in an interactive application session, wherein the state information comprises local state information specific to each of the one or more user'"'"'s unique view of the interactive application and global state information. The system of the present invention may comprise a telecommunications network; an application server in communication with the telecommunications network for managing the global state information relative to all of the users participating in the interactive application session; and at least one mobile client device in communication with the application server over the telecommunications network for managing the local state information for each of the one or more users. The method of the present invention may comprise the steps of structuring the state information for optimized delivery over the telecommunications network; and transferring the state information over the telecommunications network.

10. An interactive application server for managing global state information related to an interactive application relative to local state information received from one or more mobile client devices over a wireless communications network during an interactive application session, comprising:
-
communication means for receiving the local state information from each of the one or more mobile client devices;
a global modeler for comparing the received local state information with the global state information and updating the global state information; and
a server state manager for structuring the updated global state information for optimized delivery over the wireless communications network. - View Dependent Claims (11, 12, 13, 14)

15. A mobile client device for managing local state information related to an interactive application relative to global state information maintained by an application server during an interactive application session between one or more users over a wireless communications network, comprising:
-
a local modeler for comparing the local state information to the global state information, wherein differences between the local state information and the global state information comprise changed state information;
a client state manager for structuring the changed state information for optimized delivery over the wireless communications network; and
communication means for delivering the changed state information to the application server over the wireless communications network. - View Dependent Claims (16, 17, 18, 19)

20. A method for managing state information related to an interactive application to accommodate one or more users participating in an interactive application session, wherein the state information comprises local state information specific to each of one or more mobile client devices operated by the one or more users and global state information maintained at an application server, the method comprising:
-
comparing the local state information to the global state information at each of the mobile client devices, wherein differences between the local state information and the global state information comprise changed state information;
structuring the changed state information for optimized delivery over a wireless communications network;
delivering the changed state information to the application server over the wireless communications network; and
updating the global state information based on the changed state information received from each of the mobile client devices. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)

34. A method for managing the transfer of state information for an interactive application between at least one mobile client device maintaining local state of the interactive application information (local state information) and an interactive application server maintaining global state of the interactive application information (global state information), the method comprising the steps of:
-
determining synchronization information for synchronizing first global state information corresponding to the application server and first local state information corresponding to the at least one mobile client device;
communicating the synchronization information to the at least one mobile client device;
determining second local state information of the at least one mobile client device;
comparing the first local state information to the second local state information to determine changes in the local state information;
determining degrees of freedom corresponding to the changed local state information of the at least one mobile client device;
communicating to the interactive application server the degrees of freedom information corresponding to the changed local state information;
determining second global state information based on the changed local state information received from the at least one mobile client device; and
communicating the second global state information to the at least one mobile client device to synchronize the second global state information corresponding to the application server and the second local state information corresponding to the at least one mobile client device.
