Function requirements for mobile phone system, general 

Mobile telephone system, general 

A differentiation is made between the variants in the mobile phone system:

IMPORTANT The comfort telephony with CODE 379 (Telephone module with Bluetooth SAP) requires equipment with CODE 386 (Comfort telephony). Instead of the mobile phone cradle (accessories), the telephone module with Bluetooth® (SAP profile) can be plugged onto the Bluetooth module or the mobile phone contact plate (as of 10.05.2013).

All variants use Bluetooth® technology for data transfer. In order to be able to operate a Bluetooth-compatible mobile phone that is authorized on the audio equipment in the vehicle, the mobile phone must support the hands-free profile (HFP) 1.0 or higher.

IMPORTANT The mobile phone system is described here using basic telephony as an example. The special features of comfort telephony or telephony (with CODE 379 (Telephone module with Bluetooth SAP)) are summarized at the end of this information.

The functional scope is not only dependent on the vehicle equipment, but also on the mobile phone and the settings on the mobile phone.

IMPORTANT

IMPORTANT A mobile phone authorized on the audio equipment can also be used as a modem for access to the Internet or as a playback device as part of the Bluetooth® audio, cf. the information "Internet connection function" or "Audio mode function". A Bluetooth-compatible mobile phone here can fulfill a maximum of 2 functions at the same time. The mobile phone system includes the following areas:

Bluetooth® 

Using Bluetooth®, it is possible to connect modern communication devices such as personal digital assistants (PDA) or notebooks to the mobile phone system quickly and easily. Bluetooth® is a worldwide open standard for connecting Bluetooth® devices (e.g. mobile phone) wirelessly and is based on radio technology in the 2.4 GHz range. One advantage of Bluetooth®, in addition to the wide availability of Bluetooth® devices, is the uncomplicated and spontaneous connection of Bluetooth® devices to a Bluetooth® network (ad-hoc network). The extremely high data security (128-bit encoding) and the relatively limited radius (approx. 10 m) of this type of Bluetooth® network are what makes the use of Bluetooth® in the vehicle interesting.

The audio equipment can integrate the latest-generation mobile phones into the vehicle hierarchy via the Bluetooth® interface of the mobile phone and the Bluetooth antenna.

If several Bluetooth-compatible mobile phones are located in the vehicle, then the connection is established with the last mobile phone used in the vehicle. If this is not in the vehicle, then a search is made for a mobile phone used previous to this.

If a mobile phone has not yet been logged into the audio equipment using Bluetooth® or if the connection is to be made with another mobile phone, then the "Bluetooth telephones" or "Connect telephone" submenu item (depending on the national version) must be activated via the basic telephone function in the application bar and the "Telephone" menu item.

A list of mobile phones already recognized is displayed. This is where you can select and authorize the desired mobile phone. The "Update" entry is used to search for new mobile phones. After the update, it is possible to select and authorize the mobile phone to be connected from the displayed list.

Switch on/off characteristics 

A mobile phone operated via Bluetooth® is switched on and off on the mobile phone itself. A mobile phone operated with Bluetooth® processes the switch-on signal internally in the mobile phone. The lock code inquiry is only shown on the display of the mobile phone, if configured on the mobile phone and if the mobile phone transmits this status. The lock-code can only be entered using the mobile phone buttons. The reception status is received by the mobile phone's antenna.

The lock code and the reception status display are processed internally in the mobile phone.

The signals of the buttons on the mobile phone are processed internally by the mobile phone.

After logging into the mobile telephone network provider's mobile phone network, a display is shown on the mobile phone display and the Audio/COMAND display.

The mobile phone's switch-off signal is processed internally in the mobile phone. If the rechargeable battery of the mobile phone is empty, the mobile phone is also switched off. This process also runs internally in the mobile phone.

Establish call and terminate call 

The establish call and terminate call function consists of the following subfunctions:

Establish and terminate telephone call via the buttons on the mobile phone 

On a mobile phone operated via Bluetooth®, the control signals of the mobile phone buttons are internally processed and not forwarded to the audio equipment.

The phone call is established depending on the model and configuration either in hands-free mode or in the "Private Mode".

IMPORTANT In "Private Mode", the user makes a phone call without other vehicle occupants being able to take part in the conversation, i.e. voice input takes place via the microphone integrated in the mobile phone, and voice output takes place via the speaker integrated in the mobile phone.

When a telephone call is terminated using the mobile phone, the mobile phone interrupts the transmission or reception of mobile phone signals or data. This process runs internally in the mobile phone.

Establish and terminate telephone call via the Audio/COMAND control panel, telephone buttons or keypad on the audio unit 

The basic telephone function is called up using the Audio/COMAND control panel via the "Telephone" menu item in the application bar or using the "TEL" button on the audio unit. The basic telephone function is shown on the Audio/COMAND display. The following ways of dialing a telephone number are now available to the user:

The name of the person who you wish to call can be selected in the address book and the call lists by scrolling up and down. After dialing the telephone number via the telephone buttons on the audio equipment and pressing the "Accept phone call" button or by selecting the telephone function via the keypad on the audio equipment and then activating the "TRANSMIT" function, the telephone call is established in hands-free mode. The telephone call is terminated by pressing the "END" button on the audio equipment or by activating the "END" function in the basic telephone function.

IMPORTANT More detailed information on the speaker system is available in the "Speaker output function" information.

Establishing a call is activated in the dialog with the VCS [SBS] with the help of voice commands, e.g. with the following:

IMPORTANT The individual voice commands are listed in the "Linguatronic operator's manual".

The voice commands are registered by the hands-free system microphone and forwarded to the audio equipment over a direct line. The audio equipment sends the control signals via a direct line and the Bluetooth antenna to the mobile phone. The voice control of the voice control system (VCS [SBS]) is used to establish the telephone call in the hands-free mode.

Establish telephone call in hands-free mode 

After the telephone call has been established, the audio equipment sends the mobile phone signals or data over the Bluetooth antenna to the mobile phone. The mobile phone signals and data are received by the mobile phone via the reverse route.

The voice input in hands-free mode is recorded by the hands-free system microphone and forwarded to the audio equipment via a direct line. The audio equipment sends the signals over direct lines to the speaker system or, in vehicles with CODE 810 (Sound system), over the MOST to the sound system amplifier control unit, which amplifies the signals and transmits them to the speaker system.

IMPORTANT More detailed information on the speaker system is available in the "Speaker output function" information.

Terminate phone call in hands-free mode 

After a phone call has been terminated, the mobile phone interrupts the transmission or reception of the mobile phone signals. This takes place internally in the mobile phone.

Accepting calls, rejecting calls and toggling 

The mobile phone can be used by the user to initiate, terminate or toggle a telephone call to another person in the cellular telephone system network or in the fixed-line network. It is possible to accept, reject or toggle a call using the following components:

The accept call, reject call and toggle functions consist of the following subfunctions:

Call signal 

The mobile phone receives the call signal via the mobile phone antenna. The call signal is then forwarded to the "audio equipment" in the following way:

The audio equipment sends the ringing tone over direct lines to the speaker system or, in vehicles with CODE 810 (Sound system), over the MOST to the sound system amplifier control unit, which amplifies the signals and transmits them to the speaker system.

IMPORTANT If the mobile phone supports "In-band ringing", the mobile phone ringing is emitted over the vehicle speakers, otherwise the audio equipment 's default ringing tone is used.

The audio equipment mutes the currently active audio source (e.g. in radio mode) (MUTE). The call recognition is displayed by the audio equipment on the audio/COMAND display via a LVDS line.

IMPORTANT When "Tel" has been selected on the instrument cluster, the call recognition is indicated on the multifunction display (A1p13) in the instrument cluster. The instrument cluster receives the signals from the audio equipment via the interior CAN.

Call acceptance and rejection via the buttons on the mobile phone 

The call can be accepted or rejected by operating the mobile phone accordingly. The control signals are processed internally in the mobile phone, sent and then received by the audio equipment over the Bluetooth antenna.

Call acceptance and rejection through the Audio/COMAND control panel, telephone buttons or keypad on the audio equipment 

Selecting the "Accept" function with the Audio/COMAND control panel accepts the call in the hands-free mode and selecting the "Reject" function rejects the call. The control signals from the Audio/COMAND control panel are forwarded to the "audio equipment" via the telematics CAN.

Pressing the "Accept call" button on the "audio equipment" serves to accept the call in hands-free mode. Pressing the "End" button on the "audio equipment" rejects the call. The control signals from the buttons on the "audio equipment" are processed internally.

The control signals are sent from the audio equipment to the mobile phone via the following route:

Call acceptance and rejection via the multifunction steering wheel button groups
