Abstract

The invention-relates to a hands free mobile phone communication system comprising a mobile terminal for receiving information over a telephone connection, with a radio sender for sending said information over a selected frequency channel to an audio system, the audio system being equipped with a broadcast radio receiver and with an audio amplifier for an audio output of information received on said selected frequency channel, wherein determination means to determine an unused frequency channel, communication means for communicating said information within the communication system and switching means to switch the radio sender and the radio receiver to said determined frequency channel are comprised, and a mobile terminal and an audio system therefore.

Claims

1. A hands free mobile phone communication system comprising a mobile terminal for receiving information over a telephone connection, with a radio sender for sending said information over a selected frequency channel to an audio system, the audio system being equipped with a broadcast radio receiver and with an audio amplifier for an audio output of information received on said selected frequency channel, wherein determination means for determining an unused frequency channel, communication means for communicating said information within the communication system and switching means for switching the radio sender and the radio receiver to said determined frequency channel are comprised.

2. A hands free mobile phone communication system according to claim 1, wherein coding means are comprised for modification of the information to be sent to said audio system and decoding means are comprised to eliminate said modification before an audio output.

3. A hands free mobile phone communication system according to claim 1, wherein identification means in the audio system for an identification of the mobile phone and locking means for electrically locking said audio system depending on the identification result are comprised.

4. A hands free mobile phone communication system according to claim 1, wherein conversion means are comprised to convert signalling information received by the mobile terminal into speech information for audio distribution of the audio system.

5. A mobile terminal for receiving telephone information over a telephone connection, with a radio sender for sending corresponding information over a selected frequency channel to be received by an audio system equipped with a broadcast radio receiver wherein the mobile terminal comprises selection means to determine an unused frequency channel and generating means for generating a corresponding request to be received by said audio system.

6. An audio system comprising a broadcast radio receiver to receive information on a selected frequency channel, wherein identification means for an identification of a sending mobile phone and locking means for electrically locking said audio system depending on the identification result are comprised.
