| 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 users 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 the one or more 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, the at least one mobile client device including:
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; and
a client state manager for structuring the changed state information for optimized delivery over said telecommunications network,
wherein the client state manager structures the changed state information based on degrees of freedom associated with the
interactive application.
