  • the "vocodec” 3 is intended to encode and compress voice data to send, according to a compression rate compatible with the bit rates of data supported by the cellular network 100, and to decode and to decompress received voice data.
  • the GSM block 5 includes a GSM application allowing the telephone 30 to execute a GSM communication protocol and to control the operation in GSM cellular mode of the telephone 30.
  • the telephone 30 also includes an SMS block 16, connected to the GSM block 5, comprising a memory 13 of SMS messages, intended to be sent or previously received, as well as a preparation and issuance application of SMS messages and an application for receiving and editing, here by display on the screen 11 of SMS messages, respectively represented by modules 14 and 15.
  • SMS block 16 connected to the GSM block 5, comprising a memory 13 of SMS messages, intended to be sent or previously received, as well as a preparation and issuance application of SMS messages and an application for receiving and editing, here by display on the screen 11 of SMS messages, respectively represented by modules 14 and 15.
  • the telephone 30 further comprises a tuner 18 for radio reception of the RDS 104 network, connected to a radio antenna 17, a decapsulation block 19 and a block 20 for controlling the operation of the telephone 30 in radio receiver mode, as will be explained in the description of the process.
  • the decapsulation block 19 is connected to the tuner 18 and to the SMS block 16.
  • a mode selection block 21, connected to blocks 5 and 20, is intended for activate one of the two modes, cellular and radio receiver, and to deactivate the other mode, either automatically, under the control of the block detection 4, either under the control of a user by pressing a key mode selection of the input keyboard 10, this comprising a key to program either the automatic mode selection or the "manual" selection, in other words by the user.
  • Deactivation of one modes, cellular and radio receiver is to turn off, turn off the elements associated with this mode. So to turn off cell mode GSM, the radio block 1, the detection block 4, the "vocodec" 3 and the GSM 5 block and, to deactivate the radio receiver mode, the tuner 18, the decapsulation block 19 and the control block 20.
  • the telephone 30 includes a central control unit 22, in the species a microcontroller, to which all the elements of the phone 30 are linked, and intended to run the applications and control the telephone operation.
  • the mobile phone 30, operating in cellular mode is paired with a cellular base station 105a and moves on the territory T. It leaves momentarily the zone of coverage 101 of the cellular network 100, by entering a hole coverage 103a, and is then out of range of the cellular network 100.
  • the mobile telephone 30 being in manual mode selection, a user controls activation of radio receiver mode and deactivation of cell mode, by selecting the radio receiver mode using the mode selection key of the keyboard 10.
  • the tuner 18 is then wedged automatically on the radio broadcast frequency of the closest RDS 106a broadcasting, i.e. that associated with last base station 105a to which the mobile telephone 30 was paired before leaving the cell coverage area 101.
  • the server 40 records the call number caller's telephone, and directs the call to the answering / recording machine which, if necessary, records a voice message from the caller.
  • the server 40 prepares an SMS message containing an indication received call, in this case the indication "a received call", to indicate the receiving a call, as well as the telephone number of the caller, encapsulates the SMS message in a transport envelope to through the RDS network 104, and finally transmits it to the mobile phone 30, at via the RDS 104 network.
  • the SMS message is transmitted to the telephone mobile 30 via the RDS 106a broadcast terminal.
  • the SMS message of call indication is received by the tuner 18 and then decapsulated from its transport envelope through the RDS 104 network by the decapsulation block 19.
  • the SMS message of call indication is recorded in the SMS message memory 13 and displayed on the display screen 11 by the editing block 15.
  • block 20 activates the buzzer 12 which emits a audible signal to warn the user of the reception of an SMS message.
  • the selection block 21 activates radio receiver mode and deactivates cellular mode, under the control of the detection block 4 which no longer detects the GSM 100 network.
  • the user can then activate the cellular mode of the phone again 30, using the mode selection key, thereby waking up the detection 4, in order to check whether it has come out of the cover hole 103a and whether it found again in cell coverage area 101.
  • the mobile phone 30 When the mobile phone 30 is in the coverage area cellular 101 and is paired with one of the base stations 105a, its user can select radio receiver mode, thereby activating the radio mode radio receiver and by deactivating cellular mode, using the mode selection of the input keyboard 10. Because the cell mode is disabled, phone 30 is out of range of cellular network 100 but can nevertheless receive information from the cellular network 100, at through the RDS 104 network, via the RDS broadcasting terminal 106a associated with the last base station 105a to which the telephone mobile 30 was paired before turning off cell mode, like previously explained.
  • the mode selection block 21 is arranged, when the phone 30 is in automatic mode selection and the radio receiver is selected, to wake up block 4 of detection of the cellular network 100, at determined time intervals and for short periods, in order to check regularly and automatically if telephone 30 is in cell coverage area 101, and, the if necessary, order activation of cellular mode and deactivation radio receiver mode by mode selection block 21.
  • Cellular network 100 could transmit any other type of information to the mobile phone 30, through the broadcasting network 104, as for example, in the event of an incoming call, a message, written or voice, from of the appellant. We could thus transmit to mobile phone 30 the caller's voice message recorded by the answering machine / recorder of the waiter 40.
  • DAB Digital Audio Broadcasting
  • Phone may have only one radio antenna connected to the radio reception block of the broadcasting network and to the transmission block and cellular radio reception, via a switch block intended to sort the signals received, according to their frequency, and to direct them to one of the two radio blocks, depending on whether they are signals from the broadcasting or cellular network signals.
  • information is transmitted relating to a received call, through the broadcasting network.
