Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1, an embodiment of the present application provides a communication module 100, where the communication module 100 includes: an application chip 10, a baseband chip 20 and a shared memory 30.
The application chip 10 includes an MBIM (Mobile Broadband Interface Module) Interface 11 and a first Interface 12. The MBIM interface 11 is used for communicating with an external terminal device, so that the terminal device issues a test instruction for testing. The application chip 10 is connected to the shared memory 30 through the first interface 12. After receiving the test command, the application chip 10 stores the test command in the shared memory 30 through the first interface 12.
The baseband chip 20 is also connected to the shared memory 30. The baseband chip 20 is used to synthesize a baseband signal to be transmitted or decode a received baseband signal. Specifically, the baseband chip 20 mainly performs an information processing function of the communication module 100. As in the embodiment of the present application, the baseband chip 20 is configured to read data in the shared memory 30, and after the baseband chip 20 reads a test instruction in the shared memory 30, perform a test based on the test instruction, and store response information in the shared memory 30. The application chip 10 may be further configured to obtain response information in the shared memory 30 through the first interface 12. Structurally, the baseband chip may be divided into five modules: a CPU (Central Processing Unit), a channel encoder, a digital signal processor, a modem, and an interface module. Since the above modules are well known in the art, they will not be described in detail here.
The application chip 10 may also be an integrated circuit chip with signal processing capabilities. The Application chip 10 may also be a general-purpose Processor, such as a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a discrete gate or transistor logic device, or a discrete hardware component, which can implement or execute the methods, steps, and logic blocks disclosed in the embodiments of the present Application. Further, a general purpose processor may be a microprocessor or any conventional processor or the like.
The shared Memory 30 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Programmable Read-Only Memory (EPROM), and an electrically Erasable Programmable Read-Only Memory (EEPROM). In addition, the shared memory 30 may also be used to store programs, and of course, the programs may also be directly written into the application chip 10 and the baseband chip 20, which is not limited in this application.
It should be noted that the structure of the communication module 100 shown in fig. 1 is merely an illustration, and the communication module 100 provided in the embodiment of the present application may have fewer or more components than those shown in fig. 1, or have a different configuration from that shown in fig. 1. Further, the components shown in fig. 1 may be implemented by software, hardware, or a combination thereof.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a test data transmission method according to an embodiment of the present application, where the method is applied to the application chip 10 in the communication module 100 shown in fig. 1. It should be noted that, the test data transmission method provided in the embodiment of the present application is not limited by the sequence shown in fig. 2 and the following, and the method includes: step S101-step S104.
Step S101: and receiving a test instruction sent by the terminal equipment through the MBIM interface.
Because the application chip is provided with the MBIM interface, in the embodiment of the application, the communication module communicates with the external terminal device through the MBIM interface, so that the communication module can receive the test instruction issued by the terminal device and test based on the test instruction.
Optionally, the test instruction provided in the embodiment of the present application is an AT (Attention) instruction, and the step S101 may specifically include: receiving a first signaling sent by terminal equipment through an MBIM interface; and analyzing the first signaling, and extracting a test instruction from the first signaling.
The first signaling comprises one or more AT commands. After receiving the first signaling sent by the terminal device through the MBIM interface, the communication module needs to analyze the first signaling to extract the AT instruction in the first signaling.
Therefore, in the embodiment of the application, the first signaling acquired by the MBIM interface can be directly analyzed, so that the test instruction in the signaling can be extracted, and then only the test instruction needs to be added to the first interface, so that the baseband chip can be directly tested based on the test instruction, and the response efficiency inside the communication module is improved.
In addition, after the AT command in the first signaling is extracted, the method further includes: and judging whether the instruction is valid, if the instruction is invalid, acquiring the first signaling again and analyzing, and if the instruction is valid, executing the step S102.
It should be noted that, the manner of determining whether the instruction is valid may be determining whether there is a syntax error in the instruction or whether the instruction is empty. And when the wrong grammar exists in the instruction or the instruction is null, the representation instruction is invalid, otherwise, the representation instruction is valid.
Of course, the judging mode of whether the instruction is valid or not can also be determined according to actual requirements. The terminal equipment can also directly send an AT instruction to the communication module, and the application is not limited.
Step S102: and adding the test instruction to the first interface so as to store the test instruction in the shared memory through the first interface.
After the test instruction is acquired, the test instruction is added to the first interface, so that the test instruction is stored in the shared memory through the first interface. It should be noted that, the baseband chip is also connected to the shared memory. Therefore, after the baseband chip reads the test instruction in the shared memory, the baseband chip may execute the test instruction and store the execution result (i.e., the response information) in the shared memory.
Step S103: and when the response information is read out from the first interface, packaging the response information into MBIM response information.
After the application chip adds the test instruction to the first interface, the information can be read through the first interface, that is, the information in the shared memory is read through the first interface. When the response information is read from the first interface, the response information is extracted and packaged to meet the transmission format requirement of the MBIM interface.
Step S104: and transmitting the MBIM response information to the terminal equipment through the MBIM interface.
And finally, sending the encapsulated MBIM response information to the terminal equipment through an MBIM interface so that the terminal equipment receives complete test data.
In summary, in the embodiment of the present application, the application chip further includes an MBIM interface, the test instruction sent by the terminal device is received through the MBIM interface, and the response information corresponding to the test is encapsulated as the MBIM response information, so that the terminal device obtains complete test data.
In addition, the embodiment of the application also provides a multithreading implementation mode. Specifically, the application chip comprises an MBIM thread, a write thread and a read thread.
Referring to fig. 3, fig. 3 is a logic diagram of execution of each thread, and the test data transmission method may be further implemented by the following steps: receiving a first signaling sent by terminal equipment through an MBIM interface; calling an MBIM thread to analyze the first signaling, and extracting a test instruction from the first signaling; calling a write thread to add a test instruction to the first interface; calling a reading thread to read information in the first interface, and packaging response information into MBIM response information when the response information is read from the first interface; and calling the MBIM thread to send the MBIM response information to the terminal equipment through the MBIM interface.
The reading of the information in the first interface by the calling read thread may be reading the information from the first interface by the calling read thread through a poll function. It should be noted that the poll function is a function in the character device driver, and is well known in the art and will not be described herein too much.
In the embodiment of the application, the resource utilization rate of the application chip can be improved and the response rate of the application chip can be increased in a multithreading mode.
In addition, after the testing instruction in the first signaling is extracted by invoking the MBIM thread, the method further comprises the following steps: and judging whether the instruction is valid, if the instruction is invalid, acquiring the first signaling again and analyzing, and if the instruction is valid, calling the write thread.
The manner for determining whether the instruction is valid is described in the foregoing embodiments, and is not described herein.
It should be noted that the write thread and the read thread are created during the first test. Specifically, when the first signaling is received by the communication module for the first time, before the MBIM thread is invoked to analyze the first signaling, a write thread and a read thread are created, so that corresponding steps are executed through the write thread and the read thread subsequently.
Optionally, after the MBIM thread is invoked to parse the first signaling and the test instruction is extracted from the first signaling, the method further includes: the test instructions are stored in a first list.
Correspondingly, calling a write thread to add the test instruction to the first interface includes: calling a write thread to read an instruction from the first list; and after the test instruction is read from the first list, adding the test instruction to the first interface.
It should be noted that the test process may be performed in real time or non-real time, for example, after the test instruction is stored in the first list by the MBIM thread. The write thread may be called to read the instructions in the first list in real time, or may be called once every preset time to read the instructions in the first list. The preset time period may be determined according to requirements, such as 5 seconds, 30 seconds, and the like, and the application is not limited.
Because different threads have different processing contents, in the embodiment of the present application, after extracting the test instruction from the first signaling, the MBIM thread stores the test instruction into the first list, so that the write thread can directly read the instruction from the first list. This facilitates interaction between the two threads and also facilitates the write thread to use different rules to read instructions (such as real-time reading or reading every predetermined time interval as described above).
Further, before invoking the write thread to add the test instruction to the first interface, the method further comprises: and calling the write thread to judge whether the instruction is valid, if the instruction is invalid, reading the instruction from the first list again, and if the instruction is valid, adding the instruction to the first interface.
The manner for determining whether the instruction is valid is described in the foregoing embodiments, and is not described herein.
In the embodiment of the application, the validity of the instruction is determined, so that the occurrence of a result that the communication module is determined to be abnormal due to the fact that the subsequent invalid instruction is tested is avoided. In addition, the validity of the instruction is judged in the process of calling the MBIM thread and the process of writing the thread, and invalid instructions can be further eliminated.

It should be noted that the test method provided in the embodiment of the present application is not limited by the sequence shown in fig. 4 and the following, and the method includes: step S201-step S205.

Step S205: and transmitting the MBIM response information to the terminal equipment through the MBIM interface.
The specific process from step S201 to step S205 has already been described from step S101 to step S104, and will not be described repeatedly here.
