However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a dial-up networking method. The core of the embodiment is applied to a terminal device, and the method comprises the following steps: before dialing, the communication channel and the monitoring channel related to dial-up networking are detected one by one; the monitoring channel is used for monitoring whether the connection state of the terminal equipment and the network side is normal or not; after confirming that a communication channel and a monitoring channel related to dial-up networking are normal, carrying out dial-up networking; and when the monitoring channel monitors that the connection state of the terminal equipment and the network side is abnormal, the reconnection is triggered. Before dialing, the channels involved in the dialing process are detected one by one, and the next dialing can be performed only when all the channels are confirmed to be in a normal state, so that the detection of each channel is favorable for timely diagnosing the reason of dialing failure, and when the monitoring channel monitors that the connection state of the mobile terminal and the network side is abnormal, the background can automatically and timely process the abnormal condition, thereby realizing reconnection, and being favorable for improving the speed and efficiency of dialing. The implementation details of the dial-up networking method according to this embodiment are described in detail below, and the following description is only provided for easy understanding and is not necessary to implement this embodiment.
A flowchart of a dial-up networking method in this embodiment is shown in fig. 1, and specifically includes:
step 101: and detecting the communication channel and the monitoring channel related to dial-up networking one by one.
Before dialing, each channel involved in the dialing network access process needs to be confirmed whether the state is normal one by one, if the state of one channel is abnormal, the channel with the abnormal state is triggered to be detected again, and the next channel is detected after the detection result of the channel is confirmed to be normal. The monitoring channel is used for monitoring whether the connection state of the terminal equipment and the network side is normal or not; the communication channel comprises two parts: the main control module and the communication module are arranged in the terminal equipment.
Specifically, the terminal device mentioned herein refers to a device capable of implementing dial-up networking, and common terminal devices include a mobile phone, a computer, a tablet, and the like. The network side refers to a data exchange center such as a base station, a server and the like, and can establish data communication with the terminal equipment. Before detecting the state of each channel, firstly, it is required to confirm that the terminal equipment is in a ready state: and sending an attention (attention, simply referred to as "AT") instruction from the terminal equipment to the terminal adapter, and when receiving the AT instruction returned by the terminal adapter again, proving that the terminal equipment is in a ready state, and performing the following state detection on each channel.
Step 102: and after confirming that the communication channel and the monitoring channel related to dial-up networking are normal, performing dial-up networking.
Specifically, dial-up networking can be performed only when each channel is in a normal state. The detection mode of the state of each channel is similar, namely whether the resource handle returned in each channel is an effective value is checked, if the returned resource handle is an effective value, the channel is in a normal state, and if the returned resource handle is an invalid value, the channel is in an abnormal state. The mentioned resource is a component of the terminal device, such as a serial port, an Input/Output (I/O) port, and the like, and the mentioned handle refers to identification information returned by the terminal device when a certain resource is opened through an interface function. The dial-up networking means that a user has a personal computer, an external or internal Modem (Modem) and a telephone line, applies for a local ISP account number or purchases a network card, has a user name and a password, and then connects to the internet by dialing an access number of the ISP.
Step 103: and when the monitoring channel monitors that the connection state of the terminal equipment and the network side is abnormal, the reconnection is triggered.
Specifically, the monitoring channel is used for monitoring whether the connection state of the terminal device and the network side is normal or not, so when the connection state of the terminal device and the network side is abnormal, namely abnormal, the connection state returns to the initial detection step, and reconnection is performed, namely, the communication channel and the monitoring channel related to dial-up networking are detected one by one. The automatic reconnection under the abnormal condition greatly improves the efficiency of dial-up networking.
Compared with the prior art, the embodiment of the invention detects each channel involved in the dial-up networking process one by one before dial-up networking, and can carry out the next dial-up networking only when all the channels are confirmed to be in the normal state, so that the detection of each channel is favorable for diagnosing the reason of dial-up networking failure in time, and when the monitoring channel monitors that the connection state of the mobile terminal and the network side is abnormal, the background can automatically process the abnormal condition in time, thereby realizing reconnection, automatically diagnosing the reason of dial-up failure and realizing reconnection, and being favorable for improving the speed and efficiency of dial-up networking.

By initializing the hardware, the variables are restored to default values, and the control is set to the default state, so that the operation is not influenced by the previous operation result, and the accuracy of detection before dial-up networking is favorably ensured.
Step 201: the hardware is initialized.
Specifically, the hardware needs to be initialized before all the tests. Initialization is generally to perform software configuration on corresponding registers, so as to realize initialization setting. The hardware may include, but is not limited to, I/O ports and serial interfaces. The I/O port is responsible for the butt joint of the main control module and the external equipment, and the serial interface is an expansion interface in a serial communication mode and is also responsible for data transmission, so that the initialization is carried out on the hardware, and the operation is favorably ensured not to be influenced by the previous operation result.

Step 203: and after confirming that the communication channel and the monitoring channel related to dial-up networking are normal, performing dial-up networking.
Step 204: and when the monitoring channel monitors that the connection state of the terminal equipment and the network side is abnormal, the reconnection is triggered.
Since steps 202 to 204 in this embodiment are substantially the same as steps 101 to 103 in the first embodiment, the purpose is to perform state detection on each channel involved in dial-up networking, and in an abnormal situation, automatic reconnection is performed, and details are not described here.

By initializing the hardware, the variables are restored to default values, and the control is set to the default state, so that the operation is not influenced by the previous operation result, and the accuracy of detection before dial-up networking is favorably ensured.
A third embodiment of the present invention relates to a method for dial-up networking, and a specific flow is shown in fig. 3. The third embodiment is an improvement on the first embodiment, and the main improvement lies in that: in the third embodiment of the present invention, after confirming that the communication channel and the monitoring channel related to dial-up networking are both normal, the working state of the SIM card is also detected; and after the SIM card is confirmed to be in the working state, executing dial-up networking. By detecting the working state of the SIM card, the accuracy of detection before dial-up networking is further ensured.
Step 301: and detecting the communication channel and the monitoring channel related to dial-up networking one by one.
Step 302: and confirming that the communication channel and the monitoring channel related to dial-up networking are normal.
Step 303: detecting whether the SIM card is in a working state, if so, entering a step 304; otherwise, step 306 is entered.
Specifically, the SIM card is an abbreviation of a Subscriber Identity Module (SIM), also called as a Subscriber Identity Module (SIM) card or a smart card, and its chip stores the information of the digital mobile phone Subscriber, the encrypted key, the phone book of the Subscriber, and other contents, which can be used by the GSM network to identify the Subscriber Identity and encrypt the voice information of the Subscriber during the call, so that dial-up networking cannot be realized without the SIM card. Therefore, to dial up the network, it is necessary to first detect whether the SIM card is in a normal state.
Step 304: and (5) dial-up networking is carried out.
Step 305: and when the monitoring channel monitors that the connection state of the terminal equipment and the network side is abnormal, the reconnection is triggered.
Since steps 301 to 302 and 304 to 305 in this embodiment are substantially the same as steps 101 to 103 in the first embodiment, the purpose is to perform state detection on each channel involved in dial-up networking, and in case of an abnormal condition, automatic reconnection is performed, and details are not repeated here.
Step 306: and processing the exception of the SIM card.
Specifically, when the SIM card is in an abnormal condition, i.e. cannot work normally, the subsequent dial-up networking cannot be performed. The abnormal conditions of the SIM card are: the SIM card has problems during cutting, which causes overlarge or undersize or damages internal parts and the like; or the card slot bearing the SIM card has a problem, so that the SIM card can not work normally. When the SIM card is hot, the abnormal problem of the SIM card is different due to different problems of environment, human, etc., and the detailed description is omitted here, so that when the SIM card is abnormal, the corresponding processing is performed in the face of the specific problem.
