System of edge byte caching for cellular networks

The present invention is a method and system that reduces the amount of data traffic across communication links in a cellular network. In this system, the cellular device of a user receives and stores state information about a byte of data. During the implementation of the method of this invention, when a user desires to retrieve data from the Network Core, tokens containing a description of the state information for the requested data are sent to the cellular device. The cellular device can then have these tokens resolved by a Node B cell site that has stored the requested data. This approach reduces the need to resend the data from the Network Core over communications links. Further, the cellular devices can freely move from cell site to cell site with little interruption or loss of information.
