Abstract:
1. A wireless network comprising a radio access network and a plurality of terminals, which are each provided for encoding certain data to be transmitted and for forming in the same manner a key in dependence on a first and a second frame number for a connection to be set up or reconfigured between the radio access network and a terminal, in which the first frame number depends on the periodically changing number of the radio frame used for the data transmission and the value of the second frame number depends on the first frame number, and in which the terminal and/or the radio access network is provided for ascertaining, based on the value of the first frame number, whether a time delay in the formation of the second frame number is to take place in the radio access network, and whether an announcement for the formation of the second frame number is permitted to be sent to the radio access network.
