Method of providing a radio service at a remote terminal
First Claim
Patent Images
1. A method comprising:
- receiving at a remote terminal information broadcast by a commercial radio station in a broadcast radio channel, the commercial radio station having only uni-directional broadcast radio communication capability with respect to the remote terminal;
discriminating an identifier of an application within the received broadcast information;
initiating an authentication process for authenticating broadcast information received via the broadcast radio channel; and
in response to a positive authentication, enabling use of information received via the broadcast radio channel by the identified application;
wherein the authentication process is a uni-directional process that comprises discriminating a signature within the broadcast information received via the broadcast radio channel; and
verifying the signature using a digital key that is downloaded to the terminal using a bi-directional communication channel that is separate from the broadcast radio channel, where the digital key periodically is changed by a broadcaster of the broadcast information.

18. A terminal comprising:
-
a receiver for receiving information from a uni-directional broadcast by a commercial radio station in a broadcast radio channel, where the terminal has only uni-directional broadcast reception radio communication capability with respect to the commercial radio station; a processor connected with a non-transitory memory that stores computer program instructions that when loaded into the processor control operations of the terminal, where the operations comprise discriminating an identifier of an application within the received broadcast information; authenticating broadcast information received via the broadcast channel; and enabling/disabling the use of information received via the broadcast radio channel by the identified application, wherein in response to a positive authentication of the broadcast information received via the broadcast radio channel enabling the use of information received via the broadcast channel by the identified application; wherein authenticating is a uni-directional process that comprises discriminating a signature within the broadcast information received via the broadcast channel; and verifying the signature using a digital key that is downloaded to the terminal using a bi-directional communication channel that is separate from the broadcast radio channel, where the digital key periodically is changed by a broadcaster of the broadcast information.

19. A method of simultaneously providing a service to a plurality of remote terminals comprising:
-
broadcasting from a commercial radio station information in a uni-directional broadcast radio channel comprising an identifier of an application and information for use by the identified application, where the commercial radio station has only uni-directional broadcast radio communication capability with respect to each of the remote terminals; and providing a digital key, for authenticating the broadcast information, to each of the plurality of remote terminals, where the digital key is provided to each of the plurality of remote terminals separately from the uni-directional broadcast radio channel;
wherein authenticating is a uni-directional process that comprises discriminating a signature included within the broadcast information received via the broadcast radio channel; and
verifying the signature using the digital key that is downloaded to each of the remote terminals using a bi-directional communication channel that is separate from the broadcast radio channel, where the digital key periodically is changed by a broadcaster of the broadcast information;where the application is a JAVA application and is downloaded within a MIDIet where the MIDIet also defines the digital key used in the authentication process. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
