Definitions

  • the present invention relates to a method for a unidirectional, wireless signal transmission from a radio module, in particular a mobile phone, with integrated radio technology to a peripheral device.
  • the peripheral device can be, for example, a wireless Vibra signal generator or an opto signal generator.
  • a vibra signal generator generates a mechanical vibration that indicates to a person, for example, the arrival of a call.
  • An opto-signal transmitter emits an optical (light) signal for the same purpose.
  • Calls arriving at the mobile phone via a base station can be signaled to such a peripheral device, so that a user is informed of the incoming call by means of the peripheral device in the event that the user is not directly via the mobile phone from a corresponding device Hears call; for example if the mobile phone is not within range and / or hearing range of the user. It is also conceivable that a short message arriving at a mobile phone in the form of a so-called SMS (Short Message Service) is forwarded from the mobile phone to a peripheral device or at least signaled by this that an SMS is received by the mobile phone.
  • SMS Short Message Service
  • a unidirectional transmission of signals from the mobile phone to the peripheral device must first be implemented.
  • there should be a reliable connection between the mobile phone or the radio module to the peripheral device even if there is no optical connection, a so-called “non line of sight (NLOS)""between the mobile phone or the radio module and the peripheral device , This would be the case, for example, if the mobile phone is in a briefcase.
  • NLOS non line of sight
  • the wireless connection to be established should have a short range of a few meters and a low data rate of a few kbits / s. It is also desirable to minimize costs. In particular, no additional hardware should be necessary either on the radio module or mobile telephone side or on the peripheral device side.
  • a great advantage of the method according to the invention can be seen in the fact that the method is based on the use of a radio technology already present in the radio module or in the mobile phone.
  • the radio technology already integrated in the radio module or in the mobile phone such as GSM or BT, is temporarily reconfigured to transmit signals in an ISM (Industry, Scientific, Medecine) frequency band. If the cell phone is called, the cell phone receives this call from a base station, that is, from the side to the base station operating the mobile phone via a corresponding connection to the base station-mobile phone. The incoming call to the mobile phone is now signaled to the peripheral device by means of the temporarily reconfigured radio technology.
  • an ISM frequency band is selected from one of the four following ISM frequency bands: 433-434 MHz, 868-870 MHz, 902-928 MHz or 2400-2480 MHz.
  • Bluetooth is selected as the integrated radio technology.
  • GSM is selected as the integrated radio technology.
  • a GSM band 900 (890-915 MHz) is reconfigured to transmit on 902-928 MHz.
  • a GSM band 850 (824-849 MHz) is reconfigured to transmit on 868-870 MHz.
  • synthesizers that are used for GSM and UMTS, for example, cover a larger frequency range than those specified in these standards. This creates the possibility of setting frequencies that are prescribed in the ISM specifications.
  • the setting of the synthesizer can be controlled by software. For this purpose, the corresponding parameters are entered or changed in the provided registers.
  • the parameters are divider factors, which divide the basic oscillator or the oscillator system down into the desired factor.
  • the mobile phone or the radio module is reconfigured according to at least one of the abovementioned possibilities, so that the reconfigured mobile phone or radio module is no longer in a GSM in a time window that is not critical to the stability of the base station-mobile phone connection or Bluetooth mode. Only one RF transmission configuration is then used. With this measure, the mobile phone or the radio module is no longer used, for example, as a GSM or UMTS telephone, but is operated as a radio device which is described by another radio standard or radio technology. As may be advantageous for the example mentioned above, this can be a radio technology which uses ISM frequencies.
  • the radio module preferably sends a predefined one
  • the peripheral device detects the signal pattern and compares it with a signal pattern stored in the peripheral device. If a predefined correlation peak is exceeded, the peripheral device is then clearly identified as being assigned to the radio module.
  • the reconfigured mobile phone or the radio module sends, for example, a clearly predefined barcode-like RF burst uster to the peripheral device.
  • a sequence is represented on an HF carrier by OOK (On OFF Keying or ON / OFF keyboard) modulation or pulse width modulation. It is also conceivable to use a so-called PSK (phase shift keying) or ASK (amplitude shift keying) modulation to represent a sequence on an HF carrier.
  • PSK phase shift keying
  • ASK amplitude shift keying
  • Chirp codes can be used.
  • OOK modulation the RF carrier signal is switched on and off.
  • pulse width modulation the information is described by the pulse values or by the spacing of the burst pulses or RF packets.
  • PSK modulation uses the phase of the carrier signal to represent the information
  • ASK modulation uses the amplitude of the carrier signal.
  • the chirp signal uses a frequency-modulated RF carrier for information transmission. The pattern of such a sequence is then uniquely assigned to the reconfigured mobile phone or the radio module.
  • the telephone number or another unique number unique to the mobile phone or the radio module such as a so-called IMEI (International Mobile Equipment Identity)
  • IMEI International Mobile Equipment Identity
  • every GSM phone can be uniquely identified.
  • the RF burst pattern is then received in the peripheral device and subsequently compared with a signal pattern stored here. This is possible on the analog as well as on the digital level.
  • the measure of agreement of the signal pattern is the correlation increase. If a previously determined correlation peak is exceeded, the correspondence is established.
  • the field strength can be measured in a corresponding GSM frequency band in the peripheral device.
  • a receiver can be activated in the peripheral device. In this way, supply energy can be saved in the peripheral device.
  • the mobile phone or the radio module is only reconfigured according to one of the options mentioned, namely in such a way that the mobile phone or the radio module continues to transmit in GSM mode, but the Bluetooth mode is changed. From then on, only the RF transmission configuration will be used in Bluetooth mode.
  • the mobile phone or radio module is uniquely assigned to the peripheral device via a time Allocation of signals.
  • the field strength in the GSM frequency band is measured in the peripheral device according to a conventional method and a correlation device is activated when a nearby mobile phone or radio module is detected.
  • This can be, for example, wireless signaling devices such as a light-emitting diode or a vibrator, which indicate that a call is being received.
  • the correlation device subsequently checks the presence of a sequence of radio signals.
  • the receipt of this sequence is expected in a logically defined time window after the reception of a GSM burst.
  • the sequence is encoded, for example, in a temporal arrangement of RF bursts.
  • the HF part of the Bluetooth interface of the mobile telephone or of the radio module is preferably used to generate the bursts and is transmitted in the 2400 MHz ISM frequency band.
  • the burst pattern is detected as a signal pattern in the peripheral device and subsequently compared with a signal pattern stored here.
  • the detection is preferably carried out on the analog level, the correlation on the digital level.
  • the measure for the correspondence of the signal pattern is the correlation increase. If a previously determined correlation peak is exceeded, the match is established. If the correlation peak is exceeded, the peripheral device is considered addressed. Further conceivable actions, as already described, are switched on or off according to the type of application.
  • a great advantage of the present invention and the method according to the invention can be seen in the fact that an addressed, unidirectional, wireless signal transmission from a mobile phone or a radio module to a peripheral device using one already in the GSM and / or Bluetooth -Mobile phone or radio module integrated radio technology- technology is made possible.
  • the existing radio technology for signal transmission in an ISM frequency band and suitable RF modulation methods are reconfigured.
  • the radio module then takes place in the peripheral device by correlating a signal pattern sent by the mobile phone or by the radio module in the form of, for example, a specific sequence of RF bursts with a signal pattern or sequence stored in the peripheral device. If a threshold value is exceeded, appropriate actions are then carried out.
