Claim:
1. A computer-implemented method of dispatching messages in a moving object, the method executed on one or more processors, comprising: receiving a description of a spatial area; generating a hierarchical tree representation of the spatial area, the hierarchical tree representation comprising nodes that represent sub-regions of the spatial area encoded hierarchically; determining moving features associated with a node, the moving features comprising whether the node is cacheable wherein the node is defined to be cacheable if a sub-region of the spatial area represented by the node covers an area greater than a threshold size, whether the node covers more than one partition areas among multiple pre-partitioned areas, an active object list in an area covered by the node, and a latest position associated with an object in the active object list; and dispatching data associated with the moving object based on the hierarchical tree representation, the dispatching comprising at least one of caching context information associated with the moving object and context switching the context information associated with the moving object from a current region server to another region server.
