Abstract: When emergency announcements (EA) to a population in a crisis area are needed, avoiding single points of failure in the EA sending and forwarding systems is essential. We present a new concept, an extension to existing EA sending systems, which is based on real-time location information about mobile devices. Such a solution would increase the EA sending systems' robustness through redundancy and technology diversity. At the same time, these mobile emergency announcement (MEA) sending systems would increase the percentage of the threatened population that can be reached fast. The proposition is based on a set of requirements for EA sending systems, the most important of which turned out to be ensuring the authenticity and integrity of the EA information content. We found our preliminary results too optimistic: current GSM networks should not be used for sending EAs, as it is quite possible to forge SMS text messages, even to multiple GSM phones in a specific target area. The next generations of mobile phone networks (3G/UMTS and 4G) seem more promising, due to their packet-oriented architectures, as each data packet can be stamped with verifiable information about the source of the data. However, the development of communications networks with features compatible with MEA sending will demand that both authorities and independent experts take an active, early role in networks design right beside the commercial organisations. © Proceedings ISCRAM 2004.
