[0020] As known from the background technology, on a speeding train or high-speed railway, especially when the train or high-speed railway passes through a tunnel, the network signal is usually poor and cannot meet the network needs of travelers for work or leisure during the journey.

[0021] In order to solve the above problems, the embodiment of the present invention provides a 5G dual-mode vehicle-mounted CPE (Customer Premises Equipment). Figure 1 As shown, the 5G dual-mode vehicle-mounted CPE includes: a main control unit 10, a Sub6 radio transceiver unit 11, a millimeter wave radio transceiver unit 12, an antenna transceiver area 13, a communication network antenna 14, and a millimeter wave antenna 15. The Sub6 radio transceiver unit 11 is electrically connected to the antenna transceiver area 13 via a control signal line, and receives network signals in the 5G Sub6 frequency band via the communication network antenna 14 connected to the antenna transceiver area 13. The communication network antenna 14 includes but is not limited to 5G, 4G, 3G, or 2G network communication antennas and global satellite navigation system communication antennas. The millimeter wave radio transceiver unit 12 is used to receive network signals in the 5G millimeter wave frequency band via the millimeter wave antenna 15. The main control unit 10 is electrically connected to the Sub6 radio transceiver unit 11 and the millimeter wave radio transceiver unit 12 via control signal lines, and is used to control the Sub6 radio transceiver unit 11 and the millimeter wave radio transceiver unit 12 to receive 5G network signals in the corresponding frequency bands.

[0022] In this embodiment, Figure 2 As shown, the Sub6 radio transceiver unit 11 includes a Sub6 RF power amplifier 110, which is used to amplify the RF signal of the 5G Sub6 exclusive frequency band emitted by the main control unit 10, and send the amplified 5G Sub6 exclusive frequency band RF signal to the antenna transceiver area 13, and send the 5G Sub6 frequency band network signal received by the antenna transceiver area 13 from the base station to the main control unit 10.

[0023] In this embodiment, Figure 2As shown, the antenna transceiver area 13 includes an antenna filter 130, and the antenna filter 130 is used to ensure the stability and quality of the network signal of the 5G Sub6 frequency band collected by the communication network antenna 14.

[0024] In one example, Figure 2 As shown, the main control unit 10 sends a Tx_2GHz RF signal to the Sub6 RF power amplifier 110 through the 5G Sub6 signal transmitter. The Sub6 RF power amplifier 110 amplifies the Tx_2GHz RF signal into a Tx_6GHz RF signal and sends the amplified RF signal to the antenna filter 130. The antenna filter 130 then feeds the amplified RF signal back to the communication network antenna 14 to meet the 5G Sub-band RF signal frequency requirements of the wireless network corresponding to the external base station collected by the communication network antenna 14. The antenna filter 130 selectively filters the 5G Sub-6 band network signal collected by the communication network antenna 14 to block signals within a specific frequency range that are not required, thereby reducing interference with the 5G Sub-6 band network signal. The antenna filter 130 then sends the filtered 5G Sub-6 band network signal to the 5G Sub-6 signal receiver of the main control unit 10 through the Sub6 RF power amplifier 110.

[0025] In this embodiment, Figure 2 As shown, the millimeter wave radio transceiver unit 12 includes a millimeter wave power amplifier 120, which is used to amplify the radio frequency signal of the millimeter wave exclusive frequency band emitted by the main control unit 10, and send the amplified radio frequency signal of the millimeter wave exclusive frequency band to the millimeter wave antenna 15, and send the network signal of the 5G millimeter wave frequency band from the base station received by the millimeter wave antenna 15 to the main control unit 10.

[0026] In one example, Figure 2 As shown, the main control unit 10 sends the 2GHz radio frequency signal of the millimeter wave exclusive frequency band to the millimeter wave power amplifier 120 through the millimeter wave signal transmitting end. The millimeter wave power amplifier 120 amplifies the power of the 2GHz radio frequency signal to 40GHz, and transmits it to the external base station through the horizontal and vertical antenna surface arrays of the millimeter wave antenna 15. The network signal of the 5G millimeter wave frequency band returned by the base station is sent to the millimeter wave signal receiving end of the main control unit 10 through the millimeter wave power amplifier 120.

[0027] In this embodiment, Figure 2As shown, the 5G dual-mode vehicle-mounted CPE also includes a power management unit 16, which is electrically connected to the main control unit 10, the Sub6 radio transceiver unit 11 and the millimeter wave radio transceiver unit 12 respectively. The power management unit 16 provides power guarantee for the main control unit 10, the Sub6 radio transceiver unit 11 and the millimeter wave radio transceiver unit 12.

[0028] In an example, the power management unit 16 is connected to the main control unit 10, the Sub6 RF power amplifier 110 and the millimeter wave power amplifier 120 through different power outlets, and can provide power guarantees with different voltage requirements for the main control unit 10, the Sub6 RF power amplifier 110 and the millimeter wave power amplifier 120 according to actual needs. This can efficiently support the 5G dual-standard vehicle-mounted CPE to simultaneously receive network signals of the 5G Sub6 frequency band and the 5G millimeter wave frequency band without affecting each other.

[0029] In this embodiment, the power input interface and the enable pin of the power management unit 16 are connected to the vehicle power supply. Figure 2 As shown, IN is the power input interface of the power management unit 16, EN_ABEL1, EN_ABEL2 and EN_ABEL3 are the three enable pins of the power management unit 16. When the vehicle power supply is connected to IN, EN_ABEL1, EN_ABEL2 and EN_ABEL3 respectively, the power management unit 16 can be automatically enabled.

[0030] In this embodiment, Figure 2 As shown, the PWKEY pin of the main control unit 10 is connected to the power management unit 16 via the power button, and the PWKEY pin is connected in series with a capacitor and then to ground. For example, since large-capacity capacitors have the ability to store electricity, the PWKEY pin is connected to a large-capacity capacitor, for example, a 20μF capacitor. When the power button is pressed, the power management unit 16 supplies power to the main control unit 10, increasing the voltage on the PWKEY pin. When the power button is released, the PWKEY pin maintains a high voltage level, thereby preventing the main control unit 10 from being affected by external voltage fluctuations and maintaining a stable voltage state.

[0031] In one example, Figure 2As shown, the main control unit 10 is connected to the SIM card holder via a SIM interface, and the identity of the user of the 5G dual-mode vehicle-mounted CPE is authenticated using the SIM card information in the SIM card holder. For example, if the account used to log in to the 5G dual-mode vehicle-mounted CPE does not match the information on the SIM card registered by the operator with real name, the 5G dual-mode vehicle-mounted CPE cannot be unlocked. This setting can effectively prevent unauthorized operations.

[0032] In one example, the main control unit 10 is connected to the signal indicator light via a GPIO (General Purpose Input / Output, digital signal interface) interface. Figure 2 As shown, the main control unit 10 uses the GPIO1, GPIO2 and GPIO3 interfaces to connect to three indicator lights L1, L2 and L3 respectively. When the L1, L2 and L3 indicators are on at the same time, it means that the 5G network signal is good. The display of the indicator lights can help operators judge the network signal status in the current surrounding environment.

[0033] In one example, the main control unit 10 is connected to the multimedia device via a MIPI (Mobile Industry Processor Interface) interface. Figure 2 As shown, the main control unit 10 uses the MIPI1 interface and the MIPI2 interface to connect to the high-definition wide-angle camera and the voice transceiver, respectively. When the 5G dual-mode vehicle-mounted CPE fails, the operator can use the image information collected by the high-definition wide-angle camera or the voice information collected by the voice transceiver to restore the external conditions of the 5G dual-mode vehicle-mounted CPE during operation and assist in fault location.

[0034] In this embodiment, the main control unit 10 controls the Sub6 radio transceiver unit 11 and the millimeter wave radio transceiver unit 12 to receive 5G network signals of corresponding frequency bands, thereby realizing the reception of 5G network signals of different frequency bands, and realizing the flexible switching of 5G signals of different frequency bands of the CPE device in different network environments, adapting to different network coverage conditions and improving network capacity, thereby ensuring stable reception of 5G signals. Therefore, the 5G dual-standard vehicle-mounted CPE provided by the utility model can enhance the supply of network signals in fast-moving vehicles.

[0035] In one example, Figure 3As shown, during the operation of a train or high-speed railway, it usually maintains a network connection with the operator base station near the train or high-speed railway through the high-speed railway network service server. In an embodiment of the present application, one of the 5G dual-mode on-board CPEs, for example, CPE1 and CPE2, can be installed at the front and rear of the train or high-speed railway respectively. When the train or high-speed railway passes through a tunnel, the two dual-mode CPEs at the front and rear can be used to transmit network signals with the base stations installed in the tunnel, for example, 5G tunnel AAU1 and 5G tunnel AAU2, respectively, to receive network signals sent by the operator base station U1 or U2 near the tunnel, for example, using the Sub6 radio transceiver unit 11 to receive network signals in the 5G Sub6 frequency band, and using the millimeter wave radio transceiver unit 12 to receive network signals from the 5G millimeter wave frequency band. In this way, it can be ensured that when a train or high-speed railway passes through a tunnel, the 5G dual-mode on-board CPE is used to receive network signals of different frequency bands, thereby improving the coverage of the network signal and ensuring a stable and robust supply of the network signal.

Any person skilled in the art may make changes and modifications without departing from the spirit and scope of the present application. Therefore, the scope of protection of the present application shall be subject to the scope defined in the claims.
