Fig. 1 is a schematic diagram of a telematics terminal 10 for supporting a multi-sided voice call according to an embodiment of the present invention.

Fig. 1 shows a telematics terminal 10, a telematics terminal 20 installed in a vehicle, an emergency rescue center 30, and the like.

The telematics terminal 10 may be a cellular phone, including a smart phone, etc.

The telematics terminal 20 may include an Audio Video Navigation (AVN) having a bluetooth module installed therein.

Here, the telematics terminal 20 may receive (31) data including a voice call of the telematics terminal 10. For example, when a passenger in a vehicle provides a voice call using the telematics terminal 10, the telematics terminal 20 may connect (31) the corresponding voice call using bluetooth.

Further, the telematics terminal 20 may communicate with a telematics center including the emergency relief center 30 (32). The telematics terminal 20 may include a mobile communication module and may be wirelessly connected (32) to a telematics center.

When a call applied to the telematics terminal 10 is connected using bluetooth or a preset event, such as an occurrence of a car accident, the telematics terminal 20 may not release the bluetooth call (first call) and may perform a call connection (second call) with the emergency relief center 30. In accordance with the present invention, the deficiencies of conventional techniques for releasing a call can be overcome in the case of a multi-sided voice call connection.

Furthermore, when the vehicle body is disabled during a voice call with hands-free in an emergency vehicle accident, especially in an adverse situation such as a CDMA/LTE weak electric field with unstable communication, if the second call connection repeatedly attempts the emergency rescue center 30, the passenger may be in danger. The present invention aims to overcome this drawback.

The display unit 151 may display (output) information processed by the telematics terminal 100. For example, the display unit 151 may display execution image information of an application program driven by the telematics terminal 100 or information of a User Interface (UI) and a Graphical User Interface (GUI) according to the execution image information.

The sound output module 152 may output audio data received from the TMU 110 or stored in the memory 170 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, or the like. The sound output module 152 may output a sound signal associated with a function (e.g., a call signal reception sound and a message reception sound) performed by the telematics terminal 100. The sound output module 152 may include a receiver, a speaker, a buzzer, and the like. The sound output module 152 may be disposed at the left/right/front/rear of the vehicle.

The memory 170 may store data for supporting various functions of the telematics terminal 100. The memory 170 may store various application programs (or applications) driven by the telematics terminal 100, and data items and commands for the operation of the telematics terminal 100. At least some of the applications may be downloaded from an external server via wireless communication. Further, at least one part of the application program may exist on the telematics terminal 100 to prevent release of basic functions (e.g., a telephone receiving and transmitting function and an information receiving and transmitting function) of the telematics terminal 100. The application program may be driven to be stored in the memory 170 and installed in the telematics terminal 100 so as to perform an operation (or function) of the telematics terminal through the controller 180.

The telematics terminal 100 may store operations with respect to a network in which the functions of the memory 170 are performed.

The controller 180 may generally control all operations of the telematics terminal 100 other than the application-related operations. The controller 180 may process signals, data, information, etc., which are input or output through the aforementioned components and drive an application program stored in the memory 170 so as to provide or process information or functions suitable for a user.

In order to drive the application program stored in the memory 170, the controller 180 may control at least one part of the components described with reference to fig. 1. Further, in order to drive the application, the controller 180 may combine and operate at least two components included in the telematics terminal 100.

In order to implement operations, controls, or control methods of a telematics terminal according to various embodiments of the present invention, which will be described later, at least some of the aforementioned components may be operated in cooperation. Further, the operation, control, or control method of the telematics terminal may be implemented in the telematics terminal via driving of at least one application stored in the memory 170.

The signal processor 140 may process the transmitted signal and the received signal under the control of the controller 180. The processing of the transmitted signal may be referred to as Tx signal processing, and the processing of the received signal may be referred to as Rx signal processing. The signal processor 140 may process voice signals of a multi-sided voice call. The multi-sided voice call may be a first call entered through an Audio Video Navigation (AVN) and a second call entered through a telematics unit (TMU).

Here, the AVN may include audio, video, and navigation functions and may be installed in a vehicle. In particular, the AVN may include a bluetooth module between the short-range communication modules and transmit and receive data to and from the external mobile terminal. For example, it may be assumed that when a passenger of a vehicle performs a voice call using a mobile terminal, the call is attempted with hands-free. In this case, the telematics terminal 100 can provide a voice call of the passenger's mobile terminal with a hands-free using the bluetooth module of the AVN 120.

The controller 180 may set a plurality of communication paths. For example, the controller 180 may set a first call connected to an external mobile terminal through the AVN 120 using bluetooth as a first channel path. In addition, the controller 180 may set a second call connected to the telematics emergency call center through the TMU 110 as a second channel path. Although the above communication has been exemplified in the present disclosure, it is apparent that a plurality of communication channels are set by the controller 180 in practice. Therefore, according to the prior art, in which Tx signals are not simultaneously transmitted to the mobile communication module 111 or the short-range communication module 123.

Hereinafter, the present invention will be described in terms of the operation of the telematics terminal 100 performing a multilateral voice call.

Embodiments of a method for controlling a telematics terminal for providing a multi-sided voice call

Referring to fig. 3, a voice call of an external mobile terminal as a first call is connected using bluetooth (S310). The external terminal may be provided in the vehicle or within a short-range communication distance of the AVN including the bluetooth module.

In this case, the controller 180 may set a channel path for the first call connection. For channel routing, Complex Programmable Logic Devices (CPLDs) may also be used. The CPLD may determine whether only one of the two BT modules or both and the mobile communication module 111 are set. In the present disclosure, the present invention will be described according to a case in which the controller 180 sets a plurality of channels allowing a multi-sided voice call.

Further, the first call may be triggered by user input. The controller 180 may be in a standby state to receive a user input, and when the user input is input, a first call connection may be attempted. For example, when a passenger wants to perform a call with a bluetooth hands-free during a voice call using a mobile terminal, a user input including a touch, a key input, etc. may be input to the telematics terminal 100 through the display unit 151. Here, a short message, a long message, a video, etc. and a voice signal may be transmitted through the first channel path. In addition, any data may be transmitted as long as it can transmit data using bluetooth.

When the first call is connected, the controller 180 may connect the telematics emergency center and the second call according to a preset event (S320).

Here, the preset event may correspond to a case in which a problem such as an occurrence of a car accident, a user input for connecting with a telematics first aid center is input, and the like. However, the present invention is not limited thereto, and the case where the second call is triggered may be widely configured as long as the case is preset.

The telematics emergency center may be one of servers supported by the telematics center, and may receive SOS, automatic failure notification (ACN), etc., received from the telematics terminal in order to provide an emergency call service for a case in which a problem occurs in the vehicle.

The controller 180 may control the AVN 120, the TMU 110 and the signal processor 140 so as to simultaneously perform a first call connected to the external mobile terminal through the AVN using bluetooth and a second call connected to the telematics emergency center through the TMU.

Here, the controller 180 may set a second channel path of a signal transmitted through the second call.

The at least one voice output module may be disposed in a vehicle. An example of a speech output module will be described in terms of the aforementioned speaker. For example, the speakers may be provided at the left, right, front, and rear of the vehicle.

Embodiments of Voice Signal reception for telematics terminals providing Multi-sided Voice calls

The controller 180 may control the signal processor 140 and perform voice mixing with respect to voice signals received from the first call and the second call. Here, voice mixing refers to a method for mixing a voice signal from a first call and a voice signal from a second call and receiving the voice signals of both calls through only one speaker. The received speech signal may be processed by components such as DiRaNa. In this case, the controller 180 may obtain the voice signal by mixing the first call and the second call into the vehicle through the speaker.

Also, when the signal processor 140 has a voice mixing function, inconvenience of voice signals respectively received from the TMU 110 processed by DiRaNa can be overcome.

On the other hand, when the signal processor 140 does not have the voice mixing function, the controller 180 may provide a voice signal received into the vehicle from the first call through some speakers and a voice signal received into the vehicle from the second call through some other speakers.

When a first call connected to an external mobile terminal using bluetooth is connected through the AVN 120 and a second call is not connected to the telematics emergency center through the TMU 110, the controller 180 may control the TMU 110 to repeatedly perform an attempt for the second call connection according to a preset reference. The preset reference may be a preset time interval, a preset number of connection attempts, etc. When the preset reference is 10 minutes, the controller 180 may attempt to call the telematics first aid center for 10 minutes.

According to the foregoing various embodiments of the present invention, a telematics terminal for supporting a multi-sided voice call can be used in order to handle an emergency situation without confusion, thereby improving user convenience.

Furthermore, the telematics terminal can support an opposite-side voice call, and thus a voice signal processing module of a telematics unit (TMU) is not necessary, thereby improving device efficiency and reducing costs.

The present invention can also be embodied as computer readable codes on a computer readable recording medium. The computer readable recording medium is a data storage device that can store data which can be thereafter read by a computer system. Examples of the computer-readable recording medium include a Hard Disk Drive (HDD), a Solid State Disk (SSD), a Silicon Disk Drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, and an optical data storage device, and may be implemented in the form of a carrier wave (e.g., transmitted over a network). Further, the computer may include the controller 180 of the terminal. Thus, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
