[0030] Example 1

[0031] The method embodiment provided in Embodiment 1 of the present application can be executed in a vehicle computer, a computer or a similar computing device. Taking running on a vehicle computer as an example, Figure 1 1 is a hardware structure block diagram of a vehicle computer according to an embodiment of the present application. Figure 1 As shown, the vehicle machine may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data.

It can be understood by those skilled in the art that Figure 1 The structure shown is for illustration only and does not limit the structure of the vehicle computer. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0032] The memory 104 can be used to store vehicle programs, for example, software programs and modules of application software, such as a vehicle program corresponding to a modem control method in an embodiment of the present application. The processor 102 executes various functional applications and data processing by running the vehicle program stored in the memory 104, that is, to implement the above method.

In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0034] In this embodiment, a control method for a modem applied to an Android car machine is provided. Figure 2 is a flow chart of a modem control method according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:

[0035] Step S10, establishing a Socket connection with an on-board device via Ethernet to generate a control channel, wherein the on-board device is integrated with a modem;

[0036] Step S20, sending a modem control instruction to the vehicle-mounted device through the control channel, and the vehicle-mounted device forwards the modem control instruction to the modem to control the modem to execute the modem control instruction.

[0037] In this embodiment, the vehicle-mounted device is a device integrated with a modem. This embodiment is described by taking an example in which the vehicle-mounted device uses a vehicle-mounted T-Box (Telematics Box, vehicle-mounted remote communication module) device integrated with a 5G modem.

[0038] In this embodiment, refer to Figure 4, through Ethernet ETH (Ethernet), a Socket connection is established between the Android car machine and the vehicle-mounted T-Box device to generate a control channel (such as Figure 4 The Android car machine can send the modem control command to the vehicle-mounted device through the control channel, and then the vehicle-mounted device forwards it to the modem, thereby realizing the Android car machine cross-machine control of the external modem to execute the corresponding command.

[0039] In this embodiment, the modem control instructions include dial-up Internet access instructions, voice call instructions, SMS sending instructions, or network status query instructions, etc., which are instructions used by Android to control the 5G modem to perform related functions.

[0040] The above steps establish a control channel between the Android car machine and the vehicle-mounted device through the vehicle Ethernet for transmitting modem control instructions. The Android car machine controls the external modem across the machine, allowing the Android system to directly control the modem without the need for transfer through a private protocol. In the vehicle scenario, no additional hardware interface is required. Even if the Android car machine chip itself does not have an integrated modem, the car machine can directly control the modem to perform modem functions such as voice calls, sending text messages or dialing up the Internet.

[0041] In one implementation of this embodiment, sending a modem control instruction to the vehicle-mounted device through the control channel includes:

[0042] Step A1, deploying a radio interface layer RIL client in the Android car machine, and obtaining a modem control instruction initiated by the Android car machine application layer through the RIL client;

[0043] Step A2: sending the modem control command to the RIL server of the vehicle-mounted device through the control channel.

[0044] The RIL (Radio Interface Layer) module in the Android system is one of the key components used to handle communications with mobile networks. It is responsible for establishing a communication connection between the Android device and the modem to achieve interaction with the mobile network. The RIL module usually consists of two parts: one is the Java part (RILJ), which is responsible for communicating with the application layer; the other is the Native part, which is responsible for communicating with the baseband processor. Among them, the Java part usually consists of the Telephony Manager class and the Phone State Listener class, while the Native part consists of the RIL Daemon (RILD) and the RIL library (libfibo-ril.so). RILD is an independent process that is mainly responsible for communicating with the baseband processor and communicating with the Java layer through Socket. The RIL library is a library file of the Native layer, which contains related functions for communicating with the baseband processor.

[0045] In this embodiment, modem control requests and responses are sent and received between the Android car machine and the vehicle-mounted device through the control channel. A customized RIL library (libfibo-ril.so) is deployed on the Android car machine. Libfibo-ril.so is adapted to the RILD of the Android car machine, and serves as the client RILC of RILD (i.e., the C version of RILJ). The RIL library contains relevant programs for loading by the Android system, and the relevant functions provided by the RIL library are used to realize effective communication and control of the external modem. The RIL library complies with the Android framework specification, can be provided by a third party, and has dynamic replaceability, ensuring the flexibility and scalability of the system.

[0046] The RIL client establishes a control channel with the RILD (i.e., the RIL server) on the T-Box side through Ethernet, and sends, receives, and processes RIL control messages. Specifically, the RIL client obtains the modem control command initiated by the Android vehicle application layer; the modem control command is sent to the RIL server of the vehicle-mounted device through the control channel. In one example, the voice call APP initiates a voice call command to the Android framework, and the Android framework calls the relevant functions of the RIL client, and sends the voice call command to the RIL server of the T-Box through the control channel, which is forwarded by the T-Box to the 5G modem to control the 5G modem to make a call.

[0047] In this implementation, the RIL library of the Android car machine uses the on-board Ethernet as a communication channel to interact with an external modem without the need for additional hardware interfaces, making full use of the vehicle's existing Ethernet infrastructure. This not only simplifies the hardware layout and reduces costs, but also, when the chip does not have a built-in modem, it can still control the external modem through the on-board Ethernet channel to implement modem-related functions, thereby achieving a high degree of integration capability and resource utilization efficiency.

[0048] Reference Figure 5 , the RIL library (libfibo-ril.so) provides the on Request interface to the Android RILD. When the Android application layer initiates a modem control command, the on Request() function of the RIL library is called to send the modem control command to the RILD (Qcril server) of the vehicle-mounted device through the established control channel; the Qcril server parses the modem control command into a message that the modem can recognize (such as a QMI message) according to the request id, and forwards the QMI message to the modem; the modem will process the modem control command and return a response message to the Qcril server; the Qcrilserver converts the response message and forwards it to the RIL library; the RIL library calls the request callback function On RequestComplete() and sends the response message to the Android RILD.

[0049] In this embodiment, the modem control instruction includes a dial-up Internet access instruction. After sending the modem control instruction to the vehicle-mounted device through the control channel, the method further includes:

[0050] Step A4, receiving response information sent by the vehicle-mounted device through the control channel, wherein the response information is a dial-up result of the modem dialing up to the Internet based on the dial-up Internet access instruction;

[0051] Step A5: if the response information indicates that the dial-up is successful, a virtual local area network VLAN interface is created;

[0052] Step A6, transmitting IP message data to the vehicle-mounted device through the VLAN interface, the vehicle-mounted device forwarding the IP message data to the modem, and the modem sending the IP message data to the network.

[0053] This implementation method is a business scenario in which the Android car machine directly controls the modem to dial up the Internet. The Android car machine sends a dial-up Internet access command to the vehicle-mounted device through the control channel and waits for its response. The vehicle-mounted device forwards the dial-up Internet access command to the modem, and the modem sets the APN and other parameters required for networking, as well as the authentication process to dial up the Internet. After the modem completes the dial-up Internet access, the modem returns the response information of the dial-up result to the vehicle-mounted device, and the vehicle-mounted device forwards the response information to the Android car machine through the control channel. After receiving the response message forwarded by the vehicle-mounted device, the Android car machine parses the response message to confirm whether the dial-up is successful. If the dial-up is successful, several virtual local area network VLAN interfaces are created to establish a data channel between the Android car machine and the vehicle-mounted terminal for the transmission of Internet access data, wherein the Internet access data is mainly IP message data. The Internet access data channel is mapped through the Ethernet VLAN (virtual local area network) interface and the corresponding APN (network access point name) dial-up interface. The data is routed and forwarded through policy routing to achieve this mapping relationship. The data is routed and forwarded through routing to ensure that the data can be accurately transmitted from the vehicle-mounted device to the modem. Finally, the modem sends the IP message data to the network to achieve vehicle networking. Through this implementation, the Android vehicle can use the native RIL to directly initiate a dial-up operation to the external modem, and can obtain the dial-up results, such as the IP address and interface information (the VLAN interface automatically created by the libfibo-ril.so component). It is fully compatible with the Android native modem control logic and simplifies the modem control logic.

[0054] Optionally, in-vehicle networking generally has multi-way dial-up, such as private network and public network. Therefore, in this embodiment, multiple VLAN interfaces can also be created to support multi-way dial-up. This embodiment uses Ethernet VLAN to virtualize the dial-up data channel interface and meet the multi-way dial-up requirements at the same time.

[0055] In another implementation of this embodiment, after establishing a Socket connection with the vehicle-mounted device through Ethernet and generating a control channel, the method further includes:

[0056] The message actively reported by the modem and sent by the vehicle-mounted device based on the control channel is received through the RIL client of the Android vehicle machine.

[0057] In this embodiment, the Android car machine can also receive information actively reported by the modem. A customized RIL library (libfibo-ril.so) is defined on the Android car machine. The RIL library contains some programs. After the Android car machine loads the RIL library, the programs in the RIL library can be run as the RIL client of the Android car machine. Figure 5, the modem reports QMI to the RILD of the vehicle-mounted device (the RILD of the vehicle-mounted device serves as the RIL server, i.e., Qcril server), the Qcril server converts the actively reported message into a message recognizable by Android (such as unsol id), and sends the converted message to the Android car machine, the Android car machine receives the message actively reported by the modem sent by the Qcril server based on the control channel, and calls the non-solicited callback function OnUnsolicitedResponse() to send the actively reported message to the Android RILD. In one example, when the modem receives a call or text message, it is necessary to report the call or text message to the Android car machine. When the modem detects that the dial-up network is disconnected, it is also necessary to report the message of the dial-up network disconnection to the Android car machine so that the Android car machine can re-initiate the dial-up connection. This implementation enables the network signal and other states to be directly displayed within the Android system without the need for transfer through a private protocol or the development of a special application.

[0058] This embodiment proposes a solution for an Android car machine to use an external heterogeneous modem via Ethernet. The vehicle-mounted device (such as T-Box) can be used as a universal modem for the Android car machine via Ethernet, so that the Android system can directly control the external modem to perform Internet access, phone calls, text messages and other services.

[0059] In this embodiment, a control method for a modem applied to an in-vehicle device is also provided. The in-vehicle device is integrated with a modem. Figure 3 is a flow chart of a modem control method according to an embodiment of the present application, such as Figure 3 As shown, the process includes the following steps:

[0060] Step S40, creating a transmission control protocol socket tcp socket, establishing a socket connection with the Android car machine through Ethernet, and generating a control channel;

[0061] Step S50, receiving a modem control instruction sent by the Android car machine based on the control channel;

[0062] Step S60: forwarding the modem control instruction to the modem to control the modem to execute the modem control instruction.

[0063] A new TCP socket channel is added on the vehicle-mounted device side for cross-machine communication. The Android vehicle-mounted device establishes a socket connection with the vehicle-mounted device through connect, that is, a control channel is established between the vehicle-mounted device and the Android vehicle-mounted device through Ethernet.

[0064] The vehicle-mounted device receives the modem control command sent by the Android vehicle machine based on the control channel, and forwards the modem control command to the modem to control the modem to execute the modem control command, thereby enabling the Android vehicle machine to control the modem across devices.

[0065] The above steps establish a control channel between the vehicle-mounted device and the Android car machine through Ethernet, so that the Android car machine can use an external modem (such as a heterogeneous modem on the T-Box) across machines through Ethernet. In the vehicle scenario, no additional hardware interface is required, and the vehicle machine networking can be achieved even if the Android car machine chip itself does not have an integrated modem.

[0066] In one implementation of this embodiment, the modem control instruction includes a dial-up Internet access instruction. After forwarding the modem control instruction to the modem, the method further includes:

[0067] Step C1, receiving a response message returned by the modem, wherein the response message is a networking result of the modem executing the dial-up Internet access instruction;

[0068] Step C2, forwarding the response message to the Android car machine through the control channel.

[0069] In this embodiment, the modem used by the vehicle-mounted device (such as T-Box) generally supports RILD. The RILD of the vehicle-mounted device receives the dial-up Internet access command sent by the Android car machine based on the control channel, and then forwards the dial-up Internet access command to the modem to control the modem to execute the dial-up Internet access command.

[0070] In this embodiment, the vehicle-mounted device converts the format of the forwarded message, that is, converts the dial-up Internet access command sent by the Android vehicle machine into a message recognizable by the modem (such as a QMI message), and then forwards it to the modem. After receiving the QMI message, the modem executes the corresponding dial-up command and returns a response message to the vehicle-mounted device. Similarly, the vehicle-mounted device converts the response message returned by the modem into a message recognizable by Android, and then forwards it to the Android vehicle machine, completing the entire communication process, ensuring that the Android vehicle machine and the modem can correctly parse the message and respond.

[0071] In another implementation of this embodiment, after establishing a Socket connection with the Android car machine through Ethernet and generating a control channel, the method further includes:

[0072] Step D1, receiving a message actively reported by the modem;

[0073] Step D2, forwarding the actively reported message to the Android car machine through the control channel.

[0074] In this embodiment, the modem can actively report relevant messages to the Android car machine across devices, such as the modem's network status information, etc. The vehicle-mounted device and the modem transmit messages through inter-process communication IPC, and the QMI Client of the vehicle-mounted device receives the messages actively reported by the modem's QMI Server, converts the format of the actively reported messages, and forwards them to the Android car machine through the control channel.

[0075] Through this implementation, the Android car machine can obtain status information about the mobile network or modem messages such as phone text messages in a timely manner and make corresponding adjustments.

[0076] In a specific application scheme of the present embodiment, a method for an Android system car machine to use an external heterogeneous 5G modem across machines via Ethernet is also provided, including: the Android car machine calls relevant functions of the third-party RIL library, and establishes a control channel with the RILD on the T-Box side based on Ethernet; the RILD on the T-Box side needs to add a tcpsocket channel based on the original standard RILD (the original channels are all unix domain sockets, which can only communicate locally but not across machines); the Android car machine sends the RIL control message to the RILD on the T-Box side through the control channel, and the RILD forwards it to the modem to complete the control communication.

[0077] The solution of this embodiment uses the vehicle Ethernet to enable the Android car machine to use an external modem (heterogeneous modem of T-Box), so that the Android car machine directly controls the modem to perform Internet access, phone calls, text messages and other services without adding additional hardware interfaces, and there is no need to develop additional complex control logic. This solution is equivalent to directly integrating the modem on the car machine, and the car machine can connect to the 5G network more quickly and stably, providing a smooth Internet experience for drivers and passengers. Since an external modem is actually used, it is convenient for maintenance, replacement, and upgrading, and the Android native system directly connected to the external modem has good compatibility and stability.

[0078] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present application.
