Method and device for information transmission over the air-interface between a subscriber equipment and a network equipment in a cellular mobile radio network

摘要

The method involves transmitting information via a radio interface connection secured by a security protocol.A security connection can be established/reset by the user or network device in order to send transmission frames with header, information fields in an information transmission phase.Transmitting numbered frames after establishing/resetting the security connection is delayed until frames sent before establishment/reset have arrived safely. The method involves transmitting information via a radio connection of the radio interface secured by a security protocol and an information security connection can be established or reset by the user or network device, in order to then send successive transmission frames (NFR) with header fields (HD) and information fields (INF) in an information transmission phase. The transmission of numbered transmission frames after establishing or resetting the security connection is delayed until the transmission frames sent before the establishment or reset have arrived safely. Independent claims are also included for the following: an arrangement for transmitting information via radio interface between user device and mobile radio network cellular device, a user device and a network device.
