[0023] With the development of intelligent vehicles, the integration of vehicle terminals is becoming increasingly higher. Currently, Tiantong satellite terminals mainly use Bluetooth modules to realize Tiantong satellite communication functions. The low integration level results in large size of Tiantong satellite terminals and low deployment efficiency.

[0024] In response to the above problems, the present application provides a Tiantong satellite terminal, including: an antenna port for connecting to an antenna unit outside the Tiantong satellite terminal; a Tiantong RF chip and a Tiantong satellite SIM card, the Tiantong RF chip is connected to the Tiantong satellite SIM card, and the Tiantong RF chip is connected to the antenna unit through the antenna port; a microcontroller unit MCU, connected to the Tiantong RF chip, for controlling the Tiantong RF chip to establish a connection with the Tiantong satellite through the Tiantong satellite SIM card and the antenna unit; the Tiantong RF chip includes a voice data communication pin, and the voice data communication pin is connected to the vehicle-mounted voice module outside the Tiantong satellite terminal to realize a voice call between the vehicle-mounted voice module and the Tiantong satellite. This solution integrates the MCU and the Tiantong RF chip together, and then realizes the Tiantong satellite voice call function by setting a voice data communication pin on the Tiantong RF chip. There is no need to configure a Bluetooth module in the Tiantong satellite terminal, which improves the integration of the Tiantong satellite terminal, reduces the demand for installation space, and further improves the deployment efficiency of the Tiantong satellite terminal. The Tiantong satellite terminal in the embodiment of the present application is introduced in detail below with reference to the accompanying drawings.

[0025] Figure 1 A Tiantong satellite terminal is provided in the embodiment of the present application. The Tiantong satellite terminal in the embodiment of the present application can be applied to a vehicle, which can be an electric vehicle, a fuel vehicle or a hybrid vehicle, etc., and the present application does not make any specific restrictions on this. Figure 1 The Tiantong satellite terminal 100 may include: an antenna port 110 , a Tiantong radio frequency chip 120 , a Tiantong satellite subscriber identity module (SIM) card 130 and a micro control unit (MCU) 140 .

[0026] The antenna port 110 is used to connect to an external antenna unit of the Tiantong satellite terminal 100. The external antenna unit may include one or more antennas. The antenna unit is a vehicle-mounted antenna, such as a whip antenna or a stealth antenna.

[0027] In some implementations, the antenna port 110 may refer to an antenna switch device disposed in an antenna satellite terminal. For example, the antenna port 110 may be a single-pole double-throw switch.

[0028] Tiantong RF chip 120 is connected to Tiantong satellite SIM card 130, which is connected to the antenna unit via antenna port 110. In some implementations, Tiantong RF chip 120 may also be referred to as a Tiantong satellite baseband chip. Tiantong RF chip 120 and Tiantong satellite SIM card 130 enable Tiantong satellite call functionality.

[0029] It should be understood that Tiantong satellite SIM card 130 is a SIM card designed for the Tiantong satellite phone system. Tiantong satellite phone is part of China's independently developed satellite communication system, designed to provide satellite communication services, particularly in situations where terrestrial communication networks are unavailable or unreliable, such as in remote areas, offshore operations, and emergency rescue scenarios.

[0030] The MCU 140 is connected to the Tiantong RF chip 120. The MCU 140 can be used to control the Tiantong RF chip 120 to establish a connection with the Tiantong satellite through the Tiantong satellite SIM card 130 and the antenna unit; the Tiantong RF chip 120 includes a voice data communication pin 121, and the voice data communication pin 121 is connected to the vehicle-mounted voice module outside the Tiantong satellite terminal 100, thereby forming a voice data channel between the Tiantong satellite and the vehicle-mounted voice module, and then based on this voice data channel, the voice call function between the vehicle-mounted voice module and the Tiantong satellite can be realized.

[0031] In some implementations, the voice data communication pin 121 may refer to a communication interface configured on the Tiantong RF chip 120 for voice data transmission.

[0032] In some implementations, the voice data communication pin 121 is connected to the vehicle voice module via an inter-integrated circuit sound (I2S) interface.

[0033] In some implementations, the voice data communication pin 121 supports pulse code modulation (PCM) encoding.

[0034] In some implementations, the vehicle-mounted voice module may refer to a module configured in the vehicle for voice calls. The vehicle-mounted voice module may be, for example, a microphone / speaker module or a voice Bluetooth module, and this application does not impose specific restrictions on this.

[0035] In some implementations, the MCU 140 is used to send control instructions to the Tiantong RF chip 120, and the control instructions are used to control data transmission between the Tiantong RF chip 120 and the Tiantong satellite.

[0036] The embodiments of the present application do not impose specific restrictions on the types of the above-mentioned control instructions. For example, the control instruction may be an initialization instruction, in which case the control instruction can be used to set the data transmission parameters of the Tiantong RF chip 120, such as baud rate (transmission rate), data bit length, number of stop bits, check mode, etc.; for another example, the control instruction may be a start data transmission instruction, in which case the control instruction can be used to control the start of the data transmission process of the Tiantong RF chip 120; for another example, the control instruction may be an end data transmission instruction, in which case the control instruction can be used to control the stop of the transmission process, release resources, or enter a low power consumption mode after the data transmission is completed.

[0037] In some implementations, the MCU 140 is further configured to receive a communication log (also referred to as an operation log) of the Tiantong RF chip 120 to monitor the operation status of the Tiantong RF chip 120 .

[0038] In some implementations, the Tiantong satellite terminal 100 may be directly attached to a vehicle-mounted domain controller or a telematics control and management (TCAM) controller.

[0039] According to the above description, this solution integrates the MCU 140 and the Tiantong RF chip 120, and then realizes the Tiantong satellite voice call function by setting the voice data communication pin 121 on the Tiantong RF chip 120. There is no need to configure a Bluetooth module in the Tiantong satellite terminal 100, thereby improving the integration of the Tiantong satellite terminal 100. Since the Tiantong satellite terminal 100 in this application does not need to integrate a Bluetooth module, it can reduce the size of the Tiantong satellite terminal 100 (that is, reduce the demand for installation space), further improving the deployment efficiency of the Tiantong satellite terminal 100.

One end of the filter is connected to the Tiantong RF chip 120, and the other end of the filter is connected to one end of the LNA, which is then connected to the antenna port 110. It should be understood that the filter in the RF receive path can also be referred to as a receiving filter.

[0045] In some implementations, a radio frequency transmission path is provided between the antenna port 110 and the Tiantong radio frequency chip 120. A filter and a power amplifier (PA) are provided on the radio frequency transmission path. One end of the filter is connected to the Tiantong radio frequency chip 120, and the other end of the filter is connected to one end of the PA, and the other end of the PA is connected to the antenna port 110. It should be understood that the filter in the radio frequency transmission path can also be called a transmitting end filter.

[0046] In some implementations, the filter on the RF receive path may be a surface acoustic wave (SAW) filter. In other implementations, the filter on the RF transmit path may be a SAW filter.
