Patent ID: 8111630

Claim:
A method of delivering cached information in a wireless radio access network (RAN), wherein said RAN services a plurality of users, and comprises a plurality of components, wherein said method comprises: a. logically inserting a device between a first and second component in said RAN, said device comprising a storage element, control logic and two interface modules, such that said device communicates with both said first and said second component; b. using a first of said interface modules to emulate said first component to said second component; c. using a second of said interface modules to emulate said second component to said first component; d. using said control logic in said device to identify when a data path tunnel is established and the user associated with said tunnel, and to interpret a communication from said first to said second component, so as to determine the content of said communication, wherein said communication comprises a plurality of protocol layers; e. storing content in said storage element; f. determining using said control logic whether said communication is a request for content, and if so, determining whether said requested content is stored in said storage element; and g. transmitting using said second interface module said stored content to said first component.
