DATA SHARING IN A MULTIMEDIA COMMUNICATION SYSTEM

摘要

Data Sharing in a Multimedia Communication System A method of optimising the use of transmission bandwidth in a mobile radio communication system, the method comprising, for data to be sent via the air interface from a first to a second node, generating a signature for the data content, sending the signature from the first to the second node or to an intermediate node in the transmission path, at the second node or said intermediate node comparing the signature to signatures for data stored at that node, and sending the data from the first to the second node, via the air interface, only if the received signature does not match a signature for stored data.
