DATA TRANSPORT TO MOBILE DEVICES USING A RADIO BROADCAST DATA CHANNEL

摘要

The present invention relates to method and system for providing data services to mobile device (25) via a digital radio broadcast channel, wherein data is encrypted and forwarded to a digital radio broadcast domain based on a conditional access scheme. The additional access scheme is based on existing concepts of SIM/IMSI definition and algorithms. The invention enables initial message coverage for de-veloping countries and extends rural message coverage for huge area countries, where little mobile coverage is provided.
