Their hardware design is centered around integrating cellular communication units (such as 4G and NB-IoT) and GNSS positioning units. They receive satellite positioning signals from the GNSS positioning unit via antennas and upload data using the cellular communication unit. In areas without cellular network coverage (such as oceans, deserts, and mountainous regions), satellite networks are required for communication. However, existing communication devices require multiple antennas (such as GNSS antennas and satellite communication antennas) to support both cellular and satellite network communication.

These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0050] Figure 2 A flowchart of a network switching and antenna multiplexing control method for a communication device provided in one embodiment of this application is shown below. Figure 2 As shown, the execution subject of the network switching and antenna multiplexing control method for communication equipment provided in this embodiment can be any form of electronic device. Exemplarily, this embodiment uses a communication device as the execution subject of the method. The network switching and antenna multiplexing control method for communication equipment provided in this embodiment includes the following steps:

[0051] Step S201: Determine the current communication mode.

[0052] For example, the current communication mode includes cellular network communication mode or satellite network communication mode; specifically, in cellular network coverage areas, the current communication mode is cellular network communication mode; in areas without signal, the current communication mode is satellite network communication mode.

[0053] Specifically, the system acquires the geographical location information of the communication device; determines whether the geographical location corresponding to the geographical location information is within the range of the satellite network electronic fence; if the geographical location corresponding to the geographical location information is within the range of the satellite network electronic fence, then the satellite network communication mode is determined as the current communication mode based on the geographical location information; if the geographical location corresponding to the geographical location information is not within the range of the satellite network electronic fence, then the cellular network communication mode is determined as the current communication mode based on the geographical location information.

[0054] Step S202: According to the current communication mode, the GNSS antenna is connected to the communication unit corresponding to the current communication mode through the antenna switching unit.

[0055] Step S203: According to the current communication mode, the modem is connected to the target SIM card through the SIM card switching unit; wherein the target SIM card corresponds to the current communication mode.

[0056] Among them, the antenna switching unit is, for example, a switching circuit or an RF switcher; the SIM card switching unit is, for example, a digital logic switching circuit built into the baseband chip.

[0057] Specifically, Figure 3 This is a schematic diagram of the hardware connection in the cellular network communication mode provided in the embodiments of this application, such as... Figure 3As shown, the current communication mode includes cellular network communication mode. The target SIM card is a cellular network SIM card. According to the cellular network communication mode, the GNSS antenna is connected to the GNSS receiving unit through the antenna switching unit; according to the cellular network communication mode, the modem is connected to the cellular network SIM card through the SIM card switching unit; wherein, the modem is equipped with a GNSS receiving subunit, and the satellite network SIM card is not working.

[0058] Figure 4 This is a hardware connection diagram for the satellite network communication mode provided in the embodiments of this application, such as... Figure 4 As shown, the current communication mode includes satellite network communication mode. The target SIM card is a satellite network SIM card. According to the satellite network communication mode, the GNSS antenna is connected to the modem through the antenna switching unit. The modem is equipped with a GNSS receiving subunit, that is, the GNSS antenna is communicatively connected to the GNSS receiving subunit in the modem. According to the satellite network communication mode, the modem is connected to the satellite network SIM card through the SIM card switching unit. The cellular network SIM card and the GNSS receiving unit are not working.

[0059] Step S204: Based on the GNSS antenna, the communication unit corresponding to the current communication mode, the modem, and the target SIM card, transmit and receive communication data.

[0060] Specifically, such as Figure 3 As shown, if the current communication mode is cellular network communication mode, then communication data is transmitted and received based on the GNSS antenna, GNSS receiver unit, modem, and cellular network SIM card; such as Figure 4 As shown, if the current communication mode is satellite network communication mode, the corresponding communication unit is a modem, and the target SIM card is a satellite network SIM card, then communication data is transmitted and received based on the GNSS antenna, modem, and satellite network SIM card. The modem is equipped with a GNSS receiving subunit.

[0061] In this embodiment, resource sharing in hardware design (GNSS antenna sharing) solves the problems of high manufacturing costs and redundant size of existing communication devices caused by the need for independent configuration of multiple antennas. Specifically, based on antenna multiplexing technology, an antenna switching unit is used to dynamically switch the antenna connection path: when the device needs cellular network communication, the GNSS antenna is connected to the GNSS receiving unit through the antenna switching unit; when the device needs satellite network communication, the GNSS antenna is switched to the modem through the antenna switching unit; then, the modem is connected to the target SIM card through the SIM card switching unit, so as to realize the transmission and reception of communication data based on the GNSS antenna, the communication unit corresponding to the current communication mode, the modem, and the target SIM card. This solves the problem of high manufacturing costs caused by the need for independent configuration of multiple antennas (such as GNSS antenna and satellite communication antenna) in existing communication devices to support cellular network communication and satellite network communication, as well as the problems of high energy consumption and high cost caused by long-term connection to the satellite network due to the inability to automatically switch the current communication mode; it also solves the problem of redundant size of communication devices, and reduces the risk of electromagnetic interference by reducing the number of antennas, thereby improving the stability and reliability of communication devices.

[0062] Figure 5 A flowchart of a network switching and antenna multiplexing control method for a communication device provided in another embodiment of this application is shown below. Figure 5 As shown, the network switching and antenna multiplexing control method for communication equipment provided in this embodiment... Figure 2 Based on the network switching and antenna multiplexing control method for communication equipment provided in the illustrated embodiment, this embodiment further refines the method by including the following steps:

[0063] Step S301: Obtain the geographical location information of the communication device.

[0064] Step S302: Determine whether the geographical location corresponding to the geographical location information belongs to the cell range of the cellular network cell.

[0065] Step S303: If the geographical location information corresponds to a cell within a cellular network, then the cellular network communication mode is determined as the current communication mode based on the geographical location information.

[0066] Furthermore, in one possible implementation, after determining the cellular network communication mode as the current communication mode based on geographical location information, the method further includes: detecting the cellular network signal strength; after determining that the cellular network signal meets the requirements for data communication, obtaining the cell information of the cellular network cell, such as obtaining the frequency band and PCI parameters; after obtaining the cell information of the cellular network cell, sending the device information of the communication equipment (cellular network communication registration request) to the base station or core network of the cellular network cell to request access to the cellular network, and then detecting the cellular network communication registration status; if the cellular network communication registration is successful, then step S307 and subsequent steps are executed; otherwise, based on a third preset time interval, the execution of step 301 is returned.

[0067] Step S304: If the geographic location information does not belong to the cell range of the cellular network, then determine whether the geographic location information belongs to the fence range of the satellite network electronic fence.

[0068] Among them, the satellite network electronic fence is pre-defined, for example, dividing scenes with no cellular network signal coverage (such as remote mountainous areas, deserts, and oceans) into multiple satellite network electronic fences.

[0069] Step S305: If the geographic location information corresponds to a location within the fenced area of ​​the satellite network electronic fence, then the satellite network communication mode is determined as the current communication mode based on the geographic location information.

[0070] Step S306: If the geographic location corresponding to the geographic location information does not fall within the fence range of the satellite network electronic fence, then based on the third preset time interval, return to execute step 301 and subsequent steps.

[0071] Step S307: According to the current communication mode, the GNSS antenna is connected to the communication unit corresponding to the current communication mode through the antenna switching unit.

[0072] Step S308: According to the current communication mode, the modem is connected to the target SIM card through the SIM card switching unit; wherein the target SIM card corresponds to the current communication mode.

[0073] Step S309: Based on the GNSS antenna, the communication unit corresponding to the current communication mode, the modem, and the target SIM card, transmit and receive communication data.

[0074] Specifically, such as Figure 3 As shown, if the current communication mode is cellular network communication mode, then communication data is sent and received based on GNSS antenna, GNSS receiving unit, modem and cellular network SIM card, and based on the third preset time interval, the process returns to step 301 and subsequent steps.

[0075] like Figure 4 As shown, if the current communication mode is satellite network communication mode, the corresponding communication unit is a modem, and the target SIM card is a satellite network SIM card, then communication data is transmitted and received based on the GNSS antenna, modem, and satellite network SIM card. The modem is equipped with a GNSS receiving subunit.

[0076] Specifically, the implementation steps for transmitting and receiving communication data based on a GNSS antenna, modem, and satellite network SIM card include:

[0077] Step S3091: Based on the GNSS antenna, modem, and satellite network SIM card, determine whether the silent time interval between the current time of the communication device and the time of the previous transmission of communication data meets the first preset time interval.

[0078] Step S3092: If the silent time interval does not meet the first preset time interval, then based on the second preset time interval, return to the step of determining whether the silent time interval between the current time of the communication device and the sending time of the previous transmission of communication data meets the first preset time interval.

[0079] Step S3093: If the silent time interval meets the first preset time interval, a satellite communication registration request is sent to the satellite network to establish a satellite-to-ground communication link.

[0080] Step S3094: Send and receive communication data based on the satellite-to-ground communication link.

[0081] The settings for the silent time interval, the first preset time interval, and the second preset time interval are used to avoid frequent connections to the satellite network, which would accelerate the power consumption of the communication equipment.

[0082] Furthermore, after step S304, the process further includes: disconnecting the satellite-to-ground communication link, and returning to step S301 and subsequent steps based on a third preset time interval.

[0083] The steps in this embodiment avoid the waste of power by continuously attempting to register with the cellular network within the fenced area of ​​the satellite network electronic fence. It also avoids the accelerated power consumption of the communication device due to frequent (or continuous) connections to the satellite network. At the same time, it can switch to data communication based on the cellular network in a timely manner when the geographical location information corresponds to the cell range of the cellular network. This solves the problem of high energy consumption and high cost caused by long-term connection to the satellite network due to the inability to automatically switch the current communication mode.

[0084] Furthermore, the method provided in this application embodiment further includes: while sending a satellite communication registration request to the satellite network, obtaining the registration request duration and determining whether the registration request duration exceeds a request duration threshold; if the registration request duration does not exceed the request duration threshold, then executing the step of sending a satellite communication registration request to the satellite network to establish a satellite-to-ground communication link; if the registration request duration exceeds the request duration threshold, then stopping the execution of step S3093, and returning to the execution of step S301 and subsequent steps based on a third preset time interval.

[0085] The steps in this embodiment avoid the power consumption of communication equipment caused by frequent registration attempts by the satellite network.

[0086] Furthermore, prior to step S301, the method provided in this application embodiment further includes: detecting the status of the SIM card (cellular network SIM card and satellite network SIM card), for example, excluding the case of SIM card damage / not inserted, that is, excluding the SIM card hardware-level failure, so as to ensure the execution of subsequent steps.

[0087] It is understood that the silent time interval, the first preset time interval, the second preset time interval, and the third preset time interval in the embodiments of this application can be fixed durations set manually, or they can be dynamic durations determined by the communication device according to the remaining power of the device, so as to improve the device's battery life.

[0088] In this embodiment, the implementation of steps S307-S308 is the same as that in this application. Figure 2 The implementation methods of steps S202-S203 in the illustrated embodiment are the same, and will not be described in detail here.
