Method and apparatus for providing commercial broadcasting service in cellular mobile communication network |
摘要 |
A method and an apparatus for providing only authorized mobile subscribers with a specified commercial broadcasting service in a cellular mobile communication network. A base station transmits a control signal including a common traffic ciphered key having a specified validation period through a dedicated secure signal channel assigned to a respective authorized subscriber terminal. The base station then enciphers broadcasting data from a broadcasting system with the common traffic ciphered key, for broadcasting through a common traffic broadcasting channel. The base station periodically updates the common traffic ciphered key according to the corresponding validation period. A subscriber terminal obtains the common traffic ciphered key from the control signal received through the dedicated secure signal channel, and deciphers the broadcasting signal with the obtained common traffic ciphered key to obtain therefrom the broadcasting data. The broadcasting data is displayed after a predetermined video signal processing.
