<p>Techniques and systems for controlling access to information broadcast over point-to-multipoint resources in radiocommunication systems are described. These techniques can be used to provide controllable access to broadcast information services, e.g., security quote services, sports information services, etc., which broadcast services can be provided in conjuction with more conventional cellular radiocommunication services, e.g., voice calls. Exemplary embodiments of the present invention enable subscribing users' equipment to output broadcast information using, for example, either a status variable within the remote equipment or encryption for which subscribing devices have a corresponding decryption key.</p> |
