Claim Text:
1. A method for reducing a size of data packets of a data flow exchanged on a communication path in a mobile communications system between a first entity and a second entity, wherein the data packets on said communication path comprise a concatenation of headers, wherein an outer header in the concatenation of headers is used for exchanging the data packets on the communication path between the first and second entity, wherein the method comprises the steps of: configuring a new address uniquely identifying a context comprising information for reconstructing the concatenation of headers in the data packets, replacing an address in a destination or source address field of the outer header with the configured new address, removing at least one part of at least one header other than the outer header from the concatenation of headers, prior to transmitting the data to the second entity, and transmitting the data packets with the concatenation of headers from which the at least one part of the at least one header has been removed from the first entity to the second entity via the communication path using the outer header with the configured new address in the destination or source address field.
