In mobile systems, efficient download of content to mobile devices plays an important role. Such content can be e.g. multi-media data, as music or videos, applications, and software updates for re-configurable mobile radio terminals. Future mobile radio terminals will support different radio interfaces, which will possibly be used simultaneously. For a flexible and efficient download over different radio interfaces, it has been proposed to segment the download. This means that the whole content to be downloaded is split into segments (also called packets). The segments can be loaded from different radio channels, and the receiving radio terminal collects all the segments and recombines them to form the complete content. Different segments can also be loaded simultaneously, and they don't have to be loaded in a specific order. It has been shown that splitting the content download into several sessions transmitted over different air interfaces with support of simultaneous connections for individual terminals will highly enhance the spectrum efficiency in terms of trunking gain. This download scheme is underlying the here proposed encrypting method.
