[0092] modifying the packaging file in the native framework configuration content file according to the target library file, and modifying the wireless interface layer daemon to adapt to the target library file.

[0093] The embodiment implements the function of the external communication module and the internal communication module to access the network together through the above-mentioned scheme, specifically through the application of the dual-channel communication method to the communication terminal, the communication terminal including an internal communication module and an external communication module in communication connection with the communication terminal, and through the response to the common communication request of the internal communication module and the external communication module, the preset extended framework configuration content is called, wherein the extended framework configuration content is used to make the communication terminal support the communication function of two communication modules at the same time; and based on the extended framework configuration content, the data communication of the internal communication module and the external communication module is respectively executed.

[0094] The method embodiment of the present application is based on the terminal device architecture but is not limited to the above-mentioned architecture.

[0095] The execution subject of the method embodiment can be a dual-channel communication device or a terminal device, and the dual-channel communication device is taken as an example in the embodiment.

[0096] Referring to Figure 2 , Figure 2 FIG. 1 is a flowchart of an exemplary embodiment of the dual-channel communication method of the present application. The dual-channel communication method is applied to a communication terminal including an internal communication module and an external communication module in communication connection with the communication terminal, and the dual-channel communication method includes the following steps.

[0097] Step S10, in response to the common communication request of the internal communication module and the external communication module, the preset extended framework configuration content is called, wherein the extended framework configuration content is used to make the communication terminal support the communication function of two communication modules at the same time.

[0098] Specifically, the dual-channel communication method in the embodiment of the present application is mainly applied to the communication terminal of the Android system, and the Android native framework is modified, so that the system supports the dual-card scheme, realizes the double-signal tower display and the dual-channel communication, and the internal Modem and the external Modem data channel are optional.

[0099] Optionally, the built-in communication module and the external communication module are connected, which can be connected through an interface such as a USB (Universal Serial Bus), before connecting the external module, the module parameter information in the preset document is read, and the original framework configuration content is modified based on the read module parameter information, that is, the extended framework configuration content is obtained, and in the subsequent use process, the built-in communication module and the external communication module are connected, and the extended framework configuration content is directly called to realize the built-in communication module and the external communication module to access the Internet together.

[0100] Optionally, the original framework is modified, mainly including the steps of configuring the kernel, configuring the network card driver, setting the card mode, adding the RIL (Radio Interface Layer) library file, modifying the UI (User Interface), and modifying the RILJ (RIL.java) layer code logic, to realize the function of storing and switching the data of the dual-SIM (Subscriber Identity Module) card at will. It should be noted that the implementation steps of the above steps are a preferred embodiment, and in other embodiments, part of the configuration steps can be implemented according to the existing configuration content.

[0101] Step S20, based on the extended framework configuration content, the data communication of the built-in communication module and the external communication module is respectively executed.

[0102] Further, after recognizing that the built-in communication module and the external communication module are connected, the extended framework configuration content corresponding to the external communication module is called, and then the data communication of the built-in communication module and the external communication module is executed based on the extended framework configuration content, that is, the simultaneous communication of the built-in communication module and the external communication module is realized, and in this process, the data in the SIM card in the built-in communication module and the SIM card in the external communication module can be stored and switched at will, realizing the display of dual-signal towers and dual-way communication. This function can be used to provide a Modem product with hot plug function, and improve the performance and use experience of the communication equipment.

[0103] In the embodiment, by applying the dual-channel communication method to a communication terminal including a built-in communication module and an external communication module connected with the communication terminal, a preset extended framework configuration content is invoked in response to identifying a joint communication request of the built-in communication module and the external communication module, wherein the extended framework configuration content is used to enable the communication terminal to support the communication functions of the two communication modules simultaneously; and based on the extended framework configuration content, data communication of the built-in communication module and the external communication module is respectively performed, so that the function of joint online of the external communication module and the built-in communication module is realized through the extended framework configuration content.

[0104] Referring to Figure 3 , Figure 3 is a flowchart of another exemplary embodiment of the dual-channel communication method. Based on the above Figure 2 embodiment, in the embodiment, before the step of invoking the preset extended framework configuration content, the dual-channel communication method further includes:

[0105] In step S01, the native framework configuration content of the communication terminal and the parameter information of the external communication module are acquired.

[0106] Specifically, referring to Figure 4 , Figure 4 is an Android native framework diagram in the embodiment. As shown in Figure 4 , in the Android RIL native framework, the uppermost layer is an application program, including a call, a short message, and a SIM card management, etc., mainly responsible for sending the user's instructions to the RIL Framework (also known as RILJ); the RILJ provides a general API (Application Programming Interface) for the upper layer, and is also responsible for maintaining the communication with the RILD (Radio Interface Layer Daemon) and sending the request of the upper layer to the RILD; the RILD is started with the start of the initialization process, sends the request from the RILJ to the Modem on the CP (Central Processor) side, and sends the state change of the Modem on the CP side to the RILJ, and the configuration in the native framework is the native framework configuration content of the communication terminal.

[0107] Optionally, the RILJ is an important component in the Android operating system responsible for interacting with the mobile network communication layer. In the Android system, mobile communication (such as telephone call, short message, data connection, etc.) is communicated with the mobile network module through the RILJ. Specifically, the main functions of the RILJ in the Android system include:

[0108] Communication with baseband: The mobile communication functions of an Android device are handled by the baseband chip. The RILJ acts as a bridge between the upper-layer applications and the baseband chip. Through the RILJ, various commands, requests, and configurations can be sent to the baseband chip to implement functions such as phone calls, SMS, data connections, etc.

[0109] Handling mobile network events: The RILJ is responsible for handling events and information from the mobile network module, such as incoming calls, SMS reception, network status changes, etc.

[0110] Managing communication functions: The RILJ allows applications to initiate and control mobile communication functions, such as making phone calls, sending SMS, establishing data connections, etc.

[0111] Providing API interfaces: The RILJ provides a set of API interfaces for upper-layer applications, allowing developers to interact with the mobile network through Android applications.

[0112] It should be noted that although the RILJ has "Java" in its name, it is actually a mixture of Java code and native C / C++ code, as it needs to communicate with the underlying baseband firmware, which is usually written in C / C++. The RILJ is part of the Android system, so developers usually do not need to interact with it directly, but use high-level Android APIs to use mobile communication functions. Therefore, in some new versions of the Android system, the architecture of mobile communication may change, so there may be different communication layer components sometimes.

[0113] Optionally, the configuration content corresponding to different models of external communication modules may be different, and therefore the terminal device needs to distinguish according to the parameter information of the external communication module, wherein the parameter information of the external communication module includes model information, for example, the external module with model FM150-AE-00 is taken as an example for illustration in the embodiment of the present application.

[0114] Step S02, modifying the native framework configuration content according to the parameter information to obtain the extension framework configuration content.

[0115] Reference Figure 5 , Figure 5 The extension framework for the external module in the embodiment of the present application is shown in the schematic diagram as Figure 5 shown,

[0116] Optionally, the step of modifying the native framework configuration content according to the parameter information to obtain the extension framework configuration content can include:

[0117] S021, modifying the port configuration, network card driver, startup script, library file, user interface and dialing logic in the original framework configuration content according to the parameter information, to obtain the extended framework configuration content.

[0118] Optionally, the original framework is modified, mainly including the steps of configuring the kernel, configuring the network card driver, setting the card mode, adding the RIL library file, modifying the UI and modifying the RILJ layer code logic, so as to realize the function of double SIM card data coexistence and arbitrary switching, for example, referring to Figure 6 , Figure 6 The flowchart for modifying the framework in the embodiment of the application is shown in FIG. 1, and the implementation order of configuring the kernel, configuring the network card driver, setting the card mode, adding the RIL library file, modifying the UI and modifying the RILJ layer code logic in sequence is taken as an example for description. Figure 6

[0119] Optionally, the step of modifying the port configuration, network card driver, startup script, library file, user interface and dialing logic in the original framework configuration content comprises:

[0120] modifying the kernel source code file corresponding to the port configuration in the original framework configuration content, to obtain a port configuration supporting USB-to-serial port conversion;

[0121] compiling the configuration file in the original framework configuration content to generate a driver loading file;

[0122] modifying the single-card attribute code in the startup script in the original framework configuration content into double-card attribute code;

[0123] adding a target library file in the original framework configuration content, for processing data communication of the built-in communication module and the external communication module;

[0124] modifying the code logic corresponding to the SIM user interface;

[0125] modifying the double-data dialing logic of the wireless interface layer code.

[0126] Optionally, the step of modifying the kernel source code file corresponding to the port configuration in the original framework configuration content, to obtain a port configuration supporting USB-to-serial port conversion, comprises:

[0127] performing menu configuration based on the original framework configuration content, and opening the support components in the menu configuration in sequence;

[0128] selecting a target component in the support components and saving;

[0129] ​Compiling a corresponding kernel source file based on the target component, adding ID information of the external communication module in a target array in the kernel source file to obtain a compiled kernel source file;

[0130] Burning an image file corresponding to the compiled kernel source file to obtain the port configuration supporting USB-to-serial port conversion.

[0131] Specifically, the USB port description of the external communication module FM150-AE used in the embodiment of the application is shown in Table 1:

[0132] Table 1, USB port description example table of the external communication module

[0133]

[0134] Since the external module communicates through AT communication, that is, uses AT commands to communicate, the AT command is a command set used for communication and control with modems, mobile devices, wireless modules, etc., and is used for controlling analog modems, so the kernel needs to support the USB-to-serial port conversion function, and the specific steps include:

[0135] (1) executing make menuconfig;

[0136] (2) sequentially opening components: device drivers->usb support->usb serial converter support;

[0137] (3) selecting the USB driver for GSM and CDMA modems component and saving.

[0138] Optionally, the AT command is usually a short text string starting with "AT" followed by specific commands and parameters. For example, "ATD1234567890;" can be used to dial a phone number of 1234567890.

[0139] It should be noted that different devices and device manufacturers may support different AT command sets, so reference should be made to the documents and specifications of the relevant devices when used. The AT command is usually sent and received through a serial port (such as RS-232, UART) or other communication interfaces.

[0140] Optionally, open the kernel source file kernel / drivers / usb / serial / option.c, add the VID (0x2CB7) and PID (0x0104) of the FM150 in option_ids, and other models can be set with corresponding VID and PID according to the scheme.

[0141] Optionally, recompile the kernel and burn the image file to obtain the port configuration supporting the USB-to-serial port, and the device nodes of ttyUSB0-ttyUSB4 will exist in the / dev / directory.

[0142] Optionally, the step of compiling the configuration file in the native framework configuration content to generate the driver loading file comprises:

[0143] Performing menu configuration and component selection on the native framework configuration content to determine the configuration file;

[0144] Adding the corresponding driver code file of the external communication module to the configuration file to generate the driver loading file for starting the network card of the external communication module to communicate.

[0145] Optionally, the main steps of configuring the network card driver comprise:

[0146] (1) Execute make menuconfig and select the following components:

[0147] device drivers->Network device support->usb Network Adapters->Multi-purpose USB Networking Framework

[0148] (2) Copy the driver code file to the kernel / drivers / net / usb directory, and add the following content in Makefile:

[0149] gobinet-objs+=GobiUSBNet.o QMI.o QMIDevice.o

[0150] obj-m+=gobinet.o

[0151] Optionally, after the compiling, a driver loading file, / drivers / net / usb / gobinet.ko, is generated. The current driver loading file needs to manually start or close the network card. If the driver is compiled into the kernel, the network card can be automatically started. The specific implementation manner is that the obj-m is modified to obj-y based on the above operation, and the usb0 configuration is generated by using ifconfig-a.

[0152] Optionally, the step of modifying the single-card attribute code in the boot script in the native framework configuration content into the dual-card attribute code comprises:

[0153] selecting a boot script in the native framework configuration content;

[0154] identifying whether the attribute code in the boot script is a single-card attribute code;

[0155] if the attribute code in the boot script is a single-card attribute code, modifying the single-card attribute code into a dual-card attribute code.

[0156] Specifically, in the embodiment of the application, the persist.radio.multisim.config attribute is set to ssss (single card) or dsda (dual card) according to whether a Modem is externally connected, and the card mode of the built-in module of an Android mobile phone is always set to ssss, because the built-in module of the Android mobile phone is always in a single-card mode. In addition, the current reference-ril cannot normally work in the AP (Application Processor, application processor in a mobile phone) Framework, so it is necessary to temporarily modify the UI default rild_oem1 to return a correct value, so as to ensure its normal work. By modifying the framework side of the Android, it can support the data of two cards to be stored simultaneously.

[0157] Optionally, the modifying the boot script comprises: sequentially selecting a component device / qcom / common / rootdir / etc / init.class_main.sh, setting the persist.radio.multisim.config attribute to ssss (single card) or dsda (dual card) according to whether an external communication module is connected, and always setting the card mode of the built-in module of an Android mobile phone to ssss.

[0158] Optionally, the step of adding the target library file in the native framework configuration content comprises:

[0159] compiling a reference radio interface layer in the native framework configuration content to generate a target library file;

[0160] According to the target library file, the packaged file in the native framework configuration content file is modified, and the wireless interface layer daemon is adapted to the target library file.

[0161] Optionally, the reference-ril (Reference Radio Interface Layer) refers to a basic component in the Android operating system, which is part of the Android Telephony framework and is used for communication with the mobile phone baseband chip (also known as a modem or baseband processor). Adding the reference-ril library file mainly includes:

[0162] (1) Compiling the reference-ril in the native framework configuration content to generate a reference-ril.so target library file. By generating a dynamic library file, the file can be used in the module for internal use, so that the module can support dual systems;

[0163] (2) Modify the packaged file in the native framework configuration content file, that is, msm8953_64.mk: PRODUCT_PACKAGES+=libreference-ril.so. By adding the "PRODUCT_PACKAGES+=libreference-ril.so" command line in the msm8953_64.mk file, the libreference-ril service can be added;

[0164] (3) Modify the RILD wireless interface layer daemon to adapt to the reference-ril, that is, modify the RILD framework to adapt to the dual-system reference-ril.
