Abstract:
1. An apparatus comprising a node of a telecommunications network comprising: a computer configured to execute a first function and a second function; the first function comprising a computer-implemented data compression function and configured to perform a first operation on a first portion of a packet handled by the node, the first operation comprising a data compression operation; a second function comprising a computer-implemented encryption function and configured to perform a second operation on a second portion of the packet, the second operation comprising an encryption operation; wherein the first function and the second function are configured to employ a shared transaction for operating on the packet whereby, by virtue of the shared transaction, after performance of the first operation and the second operation, the packet has less overhead attributable to the first function and the second function than if the shared transaction had not been employed in performance of the first operation and the second operation; wherein the shared transaction comprises shared information originated by one of the first function and the second function and employed by another of the first function and the second function, and wherein the shared information comprises a sequence number that is used by the first function as a master sequence number (MSN) and that is used by the second function to encrypt at least a portion of the packet.
