Description

Interface control command processing method and modem Modem device

Technical field

The present disclosure relates to the field of communications technologies, and in particular, to a method for processing interface control commands and a modem Modem device.

Background technique

The AT command (Attention Command) refers to the interface control command between the terminal equipment (TE, Terminal Equipment) and the Modem equipment (ME, Modem Equipment). Generally, the TE initiates an AT command request to the ME, and the ME requests the request to be parsed and executed. Then return the response to the AT command. The AT command is generally completed through serial communication. The processing of an AT command includes a request and a response, and the entire process can be regarded as a session.

With the explosive development of the Internet of Things, there are many chip manufacturers in the market, such as Qualcomm, MediaTek, HiSilicon, and ZTE. While the chips of different manufacturers meet the standard AT commands, they will develop some non-standard AT commands for some non-standard requirements in the market. Since there are no standards to stipulate them, non-standard AT commands developed for these non-standard requirements are various manufacturers. Different from each other.

In this way, when the user uses it, there will be problems. For example, the user's terminal device is previously adapted to the Modem of the company's Qualcomm chip. Due to the discontinuation of the chip, company A plans to provide the modem to the new MTK chip, but because of During the test of the Modem of the MTK chip, the customer found that the partial AT command of the Modem using the MTK chip is not common to the Modem of the previous Qualcomm chip. If the customer selects the Modem of the MTK chip, the client must modify the code of the terminal device side. However, the customer is a manufacturer in the medical industry. The terminal equipment mentioned has passed the relevant certification of the medical industry. If the code is modified, the relevant certification of the industry must be re-established. The cost and time required are unacceptable to the customer. of.

Specifically, as shown in FIG. 1 , the related terminal device TE is connected to the Modem device ME through a USB interface, and a chip B is integrated in the Modem device ME, and the chip B has a built-in AT command processing module. The AT command exchange process between the terminal device TE and the Modem device ME is that the terminal device TE outputs an AT command request according to its internal logic requirement, and the AT command request is sent to the Modem device ME through the USB interface, and the Modem device TE requests the AT command. Directly forwarded to the AT command processing module inside the chip B. After the AT command processing module inside the chip B parses and processes the command, the AT command response is returned to the Modem device ME, and the Modem device ME returns the AT command response through the USB interface. After receiving the AT command response from the Modem device ME, the terminal device TE can know the execution result of the AT command, and then perform the next processing according to its own logic.

Under the relevant schemes, in general, the terminal device TE and the modem device integrated with a chip need to be one-to-one. If the terminal device TE needs to replace the modem integrated with other chips, it needs to re-make the new modem. Test and modify the code of the terminal device TE.

It can be seen from the above that the application scenario of the Modem device ME adopting the related technical solution has certain limitations. If the terminal device TE is previously adapted to use the Modem device of the chip A, there are some non-standard AT commands that are not required by the chip. The terminal device TE uses the original control method to send these non-standard AT commands. When the Modem device ME using the chip B is used, the Modem device ME using the chip B cannot recognize and execute the command at this time. If adaptation is required, the terminal device TE must modify the code to send a new AT command that can be recognized by the Modem device ME using chip B. In some cases, the terminal device TE vendor, for some reason (the code needs to be re-authenticated as described above), is difficult to modify the terminal device TE code.

In addition, modifying the code on the ME side of the Modem device also takes some time to process, and sometimes it is not easy to modify the software version if it is already closed. That is to say, the versatility of the mode adaptation of the Modem device and the terminal device using the related technical solution is relatively poor.

The disclosure is directed to the adaptation of the Modem device ME and the terminal device TE in the related art. The problem of poor usability provides a variety of solutions, as follows:

Embodiment 1

As shown in FIG. 2, a method for processing an interface control command according to Embodiment 1 of the present disclosure is applied to a modem Modem device, where the processing method includes:

Step 21: Detect whether the received interface control AT command is a command that the modem device can directly perform response processing.

The AT command may be converted into a to-be-processed command that the modem device can directly perform response processing according to the command conversion table. The command conversion table can be obtained according to the relevant command set of various chips, and will not be described in detail herein.

The method for processing the interface control command provided by the first embodiment of the present disclosure can detect whether the AT command is a command that the modem device can directly perform response processing by detecting the received interface; if not, converting the AT command to a Modem device can Directly performing the response processing of the pending command, and performing corresponding response processing according to the to-be-processed command; so that the Modem device ME can be universally adapted to different terminal devices, thereby reducing unnecessary re-development process; and solving the related technology Modem The problem of poor versatility of the device ME and the terminal device TE adaptation, at the same time, improves the market competitiveness of the product and better satisfies the customer's needs.

Specifically, the step of detecting whether the received interface control AT command is a command that the modem device can directly perform response processing includes: detecting whether the received interface control AT command is a general AT command; and when the received interface controls the AT command When the command is a general AT, it is determined that the received interface control AT command is a command that the modem device can directly perform response processing; when the received interface controls the AT command to be a non-universal AT command, detecting the received interface to control the AT command. Indicates the chip type of the modem, whether it matches the chip type of the Modem device;

When the received interface controls the AT command to indicate that the chip type of the modem matches the chip type of the Modem device, it is determined that the received interface controls the AT command as a Modem device. The command capable of directly performing response processing; when the received interface controls the AT command to indicate that the chip type of the modem does not match the chip type of the Modem device, it is determined that the received interface controls the AT command to be unable to directly perform response processing on the Modem device. command.

The chip type of the modem indicated by the AT command and the chip type of the modem device do not match (not the same) when the AT command is a command that the modem device cannot directly perform the response processing; therefore, in this embodiment, The step of converting the AT command into a pending command that the modem device can directly perform response processing includes: converting the AT command to a Modem device according to a chip type of the modem indicated by the AT command and a chip type of the Modem device A pending command that can directly perform response processing.

In the actual application, the number of the AT commands of the different chips may be different. Therefore, in the embodiment, the step of performing the response processing according to the to-be-processed command includes: the number of the to-be-processed commands When the value is equal to 1, the response processing is directly performed according to the to-be-processed command, and the processing result is sent to the terminal device that sends the interface control AT command;

When the number of the to-be-processed commands is greater than 1, the pair of the to-be-processed commands are processed in response, and the N+1th to-be-processed command is processed or terminated according to the response result of the Nth to-be-processed command. (After obtaining the processing result of a pending command, the response processing of another pending command is started); wherein N is a positive integer greater than or equal to 1.

Specifically, the step of performing a response processing or an ending operation on the N+1th to-be-processed command according to the response result of the Nth to-be-processed command includes: when the processing result of the Nth to-be-processed command is successful, The response processing of the N+1th to-be-processed command is started. After all the processing results of the to-be-processed command are obtained, the processing result of the AT command is converted and the processing result is sent to the interface to control the AT command. Terminal Equipment;

That is, during the processing, regardless of whether all the pending commands have been processed, as long as there is a pending processing result of the pending processing, the operation ends, and the conversion is completed. The processing result of the AT command.

In order to ensure the integrity of the solution, the solution provided by this embodiment further includes: when yes, directly responding to the AT command.

That is, when the received interface control AT command is a command that the modem device can directly perform response processing, the corresponding response processing is directly performed.

Considering that an excessive number of AT commands may be received in a short time, the solution provided by this embodiment further includes: buffering the received interface to control the AT command.

The method for processing the interface control command provided in the first embodiment of the present disclosure will be described below.

The solution provided by the first embodiment of the present disclosure can be implemented by using a Modem device as shown in FIG. 3, and a command adaptation module is added to the Modem device ME of the embodiment of the present disclosure; as shown in FIG. 4, the command adaptation module is The internal includes a command buffer, a command conversion table, and a command conversion algorithm module; wherein the command conversion algorithm module is the core.

As shown in FIG. 3, the terminal device TE sends an AT command request to the USB interface. After receiving the AT command request A from the USB interface, the modem device ME does not directly send the command processing module to the chip B, but first sends it to the Modem device ME. Command adaptation module. The command adaptation module converts the AT command request A to form a new AT command request B, and sends the command to the command processing module of the chip B for processing. After the processing of the command processing module of the chip B is finished, the processing result, that is, the AT command response B is returned to the command adaptation module, and the command adaptation module converts the AT command response B into an AT adapted to the AT command request A. The command responds to A, and then returns to the USB interface. Finally, the terminal device TE receives the AT command response A, thereby obtaining the processing result, and then performing subsequent processing according to the processing result.

Specifically, as shown in FIG. 4, after receiving the AT command request A, the command adaptation module first caches the command buffer; the command conversion algorithm module sequentially acquires the AT command request from the command buffer, and after obtaining the AT command request A, According to the internal algorithm processing result, to the command conversion table to query, obtain the corresponding converted AT command request B, and then the AT command request B output. After receiving the AT command response B, it also according to the internal algorithm processing result, to the command conversion table to query, obtain the corresponding converted AT command response A, and then send the AT command response A It is sent to the command buffer and is finally returned to the terminal device TE.

As shown in FIG. 5, the processing flow of the command conversion algorithm module includes:

Step 51: According to the name of the input AT command request A, determine whether the AT command request A is a general protocol AT, and if yes, go to step 52, if no, go to step 53.

That is, it is judged whether the command is a general-purpose protocol AT or a non-generic chip-specific AT command.

Step 52: The AT command request A does not need to be converted, and is directly sent to the command processing module of the chip B for processing, and returns after receiving the command response A (the command response B is equivalent to A and does not need to be converted).

Step 53: Acquire the chip A to which the AT command requests A belongs.

In general, the AT commands sent by the terminal device TE can be used to know which chip the AT command is sent by the terminal device TE. For example, the AT command for setting the terminal to start is generally used by each chip manufacturer. Not the same, so the chip type of the current terminal device TE can be judged from the beginning. Subsequent commands are not required to be repeated. For example, the AT command requests A to belong to the dedicated AT command of chip A.

Step 54: Obtain the chip B inside the current Modem device ME.

Step 55: Determine whether the AT command request A needs to be converted according to the chip A and the chip B. If not (the chip A and the chip B are substantially the same chip), proceed to step 52; if (the chip A and the chip B are substantially different types of chips) ), proceed to step 56.

Step 56: Query the command conversion table, and convert the AT command request A into the AT command request B and output.

Specifically, the query converts the chip A into the AT command request conversion table of the chip B.

Step 57: It is determined whether the number of AT command requests B is plural. If not, the process proceeds to step 58, and if yes, the process proceeds to step 510.

Step 58: The number of the AT command request B is one, and is sent to the command processing module of the chip B for processing.

Step 59: After receiving the command response B, the command response B is converted into the command response A, and returned to the terminal device TE.

After the chip B returns the processing result, that is, after the command response B, the command conversion table is queried again, specifically, the query converts the chip B into the AT command response conversion table of the chip A, and the command response returned by the query is also one, for example, The command responds to A; the command responds to A to the command buffer; it waits for transmission to the terminal device TE.

Step 510: The number of the AT command request B is greater than 1, where two are used as an example, including the command request B1 and the command request B2; the command request B1 is first issued.

Step 511: After the chip B returns to the command response B1, it is determined whether the command response B1 is OK. If yes, the process proceeds to step 513. If no, the process proceeds to step 512.

That is, after the chip B returns the command response B1, the query and the operation returned to the terminal device TE are not performed first, but the result of the command response B1 is determined whether it is necessary to continue to issue the command request B2. If the command response B1 returns an error, go to step 512; if the command response B1 returns to normal, go to step 513.

Step 512: Perform the query of the command conversion table and the operation of the return command response A according to the command response B1, and no longer issue the command request B2.

Step 513: Continue to issue the command request B2.

Step 514: After receiving the command response B2, according to the command response B1 and the command response B2, the query of the command conversion table and the operation of the return command request A are performed.

The command conversion algorithm shown in FIG. 5 only needs to process the AT command conversion of one turn and one turn. For the many-to-one AT command conversion, the present disclosure considers that the AT mechanism does not allow continuous delivery of AT commands, only the current AT command. After the request receives the AT command response, the new AT command request can be issued, so for the case of many-to-one, one by one can be processed.

In addition, the command conversion table mentioned above may be as shown in the following table, including parameters such as an AT command request, a terminal device TE chip type, a Modem device ME chip type, a converted AT command request number, and a converted AT command request. The AT command correspondence of the table is obtained based on the analysis of the specific functions of the AT commands of different chips. Since the command set of each chip is well known, the technician can obtain it according to the needs, and no longer Narration.

The following table uses the two AT commands "+premode" and "+cops" as an example:

The specific application examples of the processing method of the interface control command provided by the embodiment of the present disclosure are described below.

Example one

Assume that the terminal device TE is previously adapted to the Modem device ME of the Qualcomm chip, and this time the adapter is still the Modem device ME of the Qualcomm chip:

The terminal device TE sends an AT command to request A to the USB interface; after receiving the AT command request A from the USB interface, the modem device ME sends the command to the command adaptation module; the command buffer in the command adaptation module first requests the A command from the AT command. The cache is to be extracted by the command conversion algorithm module; after the command conversion algorithm module extracts, it is determined that the AT command request A belongs to the AT command request of the Qualcomm chip or the general AT command request; and the chip in the Modem device ME is determined to be a Qualcomm chip (may be The chip type in the Modem device ME is preset in the configuration item, and the configuration item can be read to determine the chip type. Therefore, the conversion of the AT command request is not performed, and is directly sent to the command processing module in the chip;

After the execution of the command processing module in the chip, the AT command response A is returned; after receiving the AT command response A, the command conversion algorithm module returns to the terminal device TE through the USB interface; after the terminal device TE receives the AT command response A, the AT The command request is executed.

The AT command of the terminal device TE can be determined by extracting the names of the AT commands, and the chip type of the terminal device TE is recorded in the Modem. Equipment ME;

Example two

If the terminal device TE is previously adapted to the Modem device ME of the Qualcomm chip, this time is adapted to the Modem device ME of the MTK chip, but the specific AT command is issued, and the processing procedure is the same as the example one. This is not repeated.

Example three

If the terminal device TE is previously adapted to the Modem device ME of the Qualcomm chip, this time is adapted to the Modem device ME of the MTK chip. Specifically, the AT command of the Qualcomm chip needs to be converted into an AT command of one MTK chip. Here, taking the AT command +prefmode of the Qualcomm chip as an example, the command needs to be converted to MTK's AT command +erat:

The terminal device TE sends an AT command request +premode to the USB interface; after receiving the AT command request +prefmode from the USB interface, the modem device ME sends the command to the command adaptation module; the command buffer in the command adaptation module first sends the AT command. Request +prefmode cache, to be extracted by the command conversion algorithm module;

After the command conversion algorithm module extracts, according to the name prefmode of the AT command request, it is determined that the AT command request +prefmode is an AT command request belonging to the Qualcomm chip; the configuration item of the current Modem device ME is queried, and the chip in the Modem device ME is determined to be MTK. Chip, therefore need to perform the conversion of the AT command request, query the command conversion table shown above;

The command conversion algorithm module requests the name, the terminal device TE chip type, and the modem device ME chip type according to the AT command, and the query command conversion table can obtain the converted AT command request +erat, and sends the +erat to the command processing module in the chip. ;

After the execution of the command processing module in the chip, the AT command response OK is returned; after receiving the AT command response OK, the command conversion algorithm module determines whether the AT command response conversion is needed. In this embodiment, no conversion is required (only Involving a simple response, such as whether it can be executed, communicated, etc., OK is universal, when it involves substantial communication content, it needs to be converted, because the parameters of various chips may be different);

The command conversion algorithm module returns the AT command to OK, and returns to the terminal device TE through the USB interface; after the terminal device TE receives the AT command response OK, the AT command request is completed.

Example four

If the terminal device TE is previously adapted to the Modem device ME of the Qualcomm chip, this time is adapted to the Modem device ME of the MTK chip. Specifically, one AT command of the Qualcomm chip needs to be converted into an AT command of two MTK chips. Here, taking the AT command +cops of Qualcomm chip as an example, the command needs to be converted to +cops and +erat of MTK. The main difference between this example and the above example is the processing of the command conversion algorithm module:

The terminal device TE sends an AT command request +cops to the USB interface; after receiving the AT command request +cops from the USB interface, the modem device ME sends the command to the command adaptation module; the command buffer in the command adaptation module first sends the AT command. Request +cops cache, to be extracted by the command conversion algorithm module;

After the command conversion algorithm module extracts, according to the chip type of the current terminal device TE that is previously determined, it is determined that the AT command request +cops is an AT command request belonging to the Qualcomm chip (since the AT commands of different chips in the initialization phase are generally different, By extracting the names of the AT commands, the type of the currently adapted terminal device TE can be determined, and the type of the terminal device TE is recorded in the Modem device ME);

Query the configuration item of the ME type of the current modem device, and determine that the chip in the Modem device ME is an MTK chip. Therefore, the conversion of the AT command request is required, and the command conversion table shown above is queried;

The command conversion algorithm module requests the name, the terminal device TE chip type, and the modem device ME chip type according to the AT command, and the query command conversion table can obtain the converted AT command request +cops and +erat, and first convert the first converted AT command. Request +cops to be sent to the command processing module in the chip;

After the execution of the command processing module in the chip, the AT command returns OK; after receiving the first AT command response OK, the command conversion algorithm module sends an AT command request +erat to the command processing module in the chip (if received) The response of the first AT command is ERROR, then the AT command is not required to be sent +erat, but the ERROR is directly returned to the terminal device TE);

After the execution of the command processing module in the chip, return the AT command response OK; command to After receiving the second AT command response OK, the algorithm module determines whether it is necessary to perform the conversion of the AT command response. In this embodiment, no conversion is required (the reason is the same as the content in the third example);

It can be seen from the above that the solution of this embodiment provides an AT command matching conversion method on the relevant Modem, which allows the customer to ignore the difference of the control methods brought by different chips when using the Modem, and minimize the reduction to the client. The impact of this, thereby enhancing the competitiveness and flexibility of the product.

In summary, the solution proposed by the embodiment of the present disclosure can make the Modem device ME universally adapt to different terminal devices, reduce unnecessary re-development process, and improve user experience;

For example, the terminal device is previously adapted to the Modem device ME of the Qualcomm chip. Therefore, part of the code execution in the terminal device is a dedicated AT command of the Qualcomm chip. Under the related technical solution, if the Modem device ME using the MTK chip is to be adapted, , then either modify the terminal device code, or re-develop the software version of the MTK chip Modem device ME, and these modifications are either laborious or impossible to receive by the customer;

With the solution of the present disclosure, the Modem device ME using the MTK chip can easily replace the Modem device ME of the Qualcomm chip without modifying the code of the terminal device, thereby improving the market competitiveness of the product and satisfying the customer's needs.
