Fig. 2 is a schematic diagram of software module composition of the home gateway in the embodiment of the present invention.
Referring to fig. 1, the core software processing of the present invention is performed in the main processor module 101 and the wireless data card 102 of fig. 1. The software design follows the idea of modular design, and modules are divided according to specific functions. As shown in fig. 2, the software modules of the home gateway of the present invention include: a Linux operating system module 201, a hardware driving module 202, a BootLoader program module 203, a daemon module 204, an Internet firewall module 205, a call management module 206, a Web Server module 207, a log management module 208, an AT command processing module 209, a CGI (Common Gateway Interface) program module 210, a Web page module 211, and a wireless data card program module 212; wherein,
a Linux operating system module 201, configured to complete functions of a general operating system and schedule operation of the entire home gateway, for example: process start, delete, interprocess communication, memory management, clock management, file management, etc.
And the hardware driver module 202 is used for providing an interface between hardware and the Linux operating system module 201. The Linux operating system module 201 can control the operation of the hardware device only through the interface. Some interface functions are provided in the hardware driver module 202.
Since the BootLoader program module 203 is the first program to run after the Linux operating system module 201 is powered on, the BootLoader program module 203 is used to initialize some peripheral devices, such as: and peripherals such as a serial port, a network port and the like are responsible for loading the kernel of the Linux operating system module 201 and the file system.
The daemon module 204 is used for managing application layer modules, such as: maintenance of a main state machine of an application layer, monitoring of operation conditions of other modules of the application layer and the like. The daemon module 204 is an independent process, and requires the design to be as concise as possible.
The Internet firewall module 205 is configured to protect the security of the home internal network through IP filtering and the like, and may also limit the right of the home internal network user to access the external wireless network.
The call management module 206 is used for controlling a call flow and the like when the voice service is performed with the home gateway through the external telephone.
The Web Server module 207, as an independent process, is used to process the user request from the Web page module 211 and send the user request to the CGI program module 210 for processing. The Web Server module 207 is also used to receive the processing result from the CGI program module 210 and send the processing result back to the Web page module 211 for display to the user. The Web page module 211 is a Web page file that is defined in advance and stored in the FLASH of the storage module 103.
The log management module 208 is configured to record some important information during the operation of the home gateway, for example: the home gateway generates abnormal error information, home gateway starting information, home gateway closing information, incoming call number information and the like in the running process.
The AT command processing module 209 is used for generating AT commands, analyzing AT command responses, identifying the formats of the wireless data cards 102, adapting to AT commands of wireless data cards 102 of different formats, and the like.

Different information corresponds to different AT commands. The information sent by the daemon sub-module 204 corresponds to the AT command sent by the AT command processing module 209 one by one. Different AT commands correspond to different uses, such as: the AT null command may be used to detect whether the wireless data card 102 is inserted after the home gateway is started, the AT $ card type command is used to detect the format of the wireless data card 102, and the like. Since the definitions of the AT commands of the wireless data cards 102 of different formats generally differ, an important function to be performed by the AT command processing module 209 is: adapting the AT commands of the wireless data cards 102 of different formats, that is, after the home gateway is started, the format of the wireless data card 102 is identified, then the format flag of the wireless data card 102 is set, and the branch flow corresponding to the wireless data card 102 of the current format in the AT command processing module 209 is started. The branch flow, i.e. the data interaction processing flow with the wireless data cards of different systems, will execute different software branches in the AT command processing module 209 according to the systems of the wireless data cards. The wireless data card 102 of each system corresponds to a service flow executed by processing the AT command in the AT command processing module 209.
The AT command processing module 209 is a key module for implementing the automatic adaptation of the home gateway to the wireless data cards of multiple standards, and the implementation scheme for the home gateway to automatically adapt to the wireless data card 102 is implemented in the module, and the specific internal structure of the module will be described in fig. 4.

The wireless data card program module 212 is used for implementing various software functions of the wireless data card 102, and is a software system in the wireless data card 102. The software in each wireless data card 102 has a function of identifying AT commands, and when the wireless data card 102 inserted into the home gateway receives an AT command, a response is generated to the AT command, and the content of the response includes parameters, such as: the format of the wireless data card 102. For example: when a wireless data card 102 with CDMA system inserted into the home gateway receives the AT $ CARDTYPE command, the wireless data card responds to the command, and the response content is CDMA system of the wireless data card 102.
Fig. 3 is a flowchart illustrating a method for automatically adapting a home gateway to a wireless data card according to an embodiment of the present invention.
With reference to fig. 2, the method for the home gateway to automatically adapt to the wireless data card of the present invention is mainly implemented in the AT command processing module 209 of the software module of fig. 2. As shown in fig. 3, the method for automatically adapting a wireless data card by a home gateway specifically includes the following steps:
step 301-303: after the home gateway is started, whether the wireless data card 102 is inserted into the home gateway is detected. This can be done by issuing AT commands or by reading the pin status of the data card interface. If no wireless data card 102 is detected, go to step 308; if a wireless data card 102 is detected, go to step 304.
The specific method for detecting whether the wireless data card 102 is inserted into the home gateway through the AT command includes: after the home gateway is started, after the daemon module 204 sends information to the AT command processing module 209, the AT command processing module 209 starts to send an AT command to the wireless data card 102, if no response is received within the configured maximum response times, it indicates that the wireless data card 102 is not inserted in the home gateway, and if a response is received within the configured maximum response times, it indicates that the wireless data card 102 is inserted in the home gateway. The AT command may be an AT null command or other AT commands for detecting whether the wireless data card 102 is inserted into the home gateway.
The specific method for detecting whether the wireless data card is inserted into the home gateway or not by reading the state of the data card interface pin comprises the following steps: when the home gateway is started, after the daemon module 204 sends a signal to the AT command processing module 209, the AT command processing module 209 calls an interface function provided in the hardware driving module 202, and the interface function drives the hardware system. In the hardware system, the pin of the main processor module is connected to the pin of the wireless data card through a line, at this time, when the pin of the main processor module 101 is low, it indicates that the wireless data card 102 is not inserted in the home gateway, and when the pin state of the main processor module and the pin state of the wireless data card 102 are both high, it indicates that the wireless data card is inserted in the home gateway.
Step 304-307: the format of the wireless data card 102 is detected. The AT command processing module 209 sends a format detection command to the wireless data card 102, for example: an AT $ CARDTYPE command, and then the system of the wireless data card 102 is determined according to the return value of the wireless data card 102 to the system detection command; next, the AT command processing module 209 sets a format flag of the wireless data card 102, for example: the system of the wireless data card 102 is identified through a global variable or a global mark written in the configuration data; since there are multiple branch flows corresponding to different types of wireless data cards in the home gateway, then the AT command processing module 209 starts the branch flow corresponding to the wireless data card 102 in the current type in the AT command processing module 209 according to the type flag of the wireless data card 102, and the home gateway enters a normal working state. In this state, the user can perform local services through the home gateway, and can connect to an external wireless network through the wireless data card 102 connected to the home gateway, and access to the Internet, etc.
In step 304, the return value and the format of the wireless data card 102 are in a one-to-one correspondence relationship, and the format of the wireless data card 102 can be determined by the return value. In step 306, for the wireless data cards 102 of different systems, different branch flows are executed in the AT command processing module 209, so that the branch flow corresponding to the wireless data card 102 of the current system in the AT command processing module 209 can be determined to be enabled according to the different system flags of the wireless data card 102.
Step 308: the home gateway enters a local service state. In this state, the home gateway can only provide some services locally, such as: local area networking, managing local intelligent devices, and the like. In the local service state, the user can only execute local services, and cannot be connected to an external wireless network through a home gateway, so that the user cannot access the Internet.
After the AT command processing module 209 completes the detection of the wireless data card 102, the detection result is written into a database, and a message is sent to the Web page module 211 to notify the Web page module 211 to read the database in which data has been written before, so as to display information such as whether the home gateway detects the wireless data card 102, the system of the wireless data card 102, and the state of the home gateway to the user.
