The invention relates to a system and method for analog phone AT command testing.

With the development of mobile communication technology and the continuous enrichment of mobile services, mobile phones have become an indispensable high-tech product in people's daily life. The mobile phone industry is also becoming more and more powerful, and the competition is becoming more and more fierce. It is said that how to quickly develop a new type of mobile phone with rich software functions has become an important weight to enhance market competitiveness.

According to international standards, the mobile terminal is provided by the AT commands when it is provided to the mobile application service. The mobile application runs on the terminal equipment (TE), and the mobile phone protocol related program runs on the mobile terminal ( On the Mobile Terminal (MT), the TE communicates with the MT through a Terminal Adapter (TA), wherein the service provided by the TA to the TE is an AT command. The AT command is a very regular interface. By analogizing the behavior of the AT command, the mobile application can feel that it is running in a real environment, thereby reducing the complexity of the analogy of the analog mobile terminal.

The traditional analog AT command method is to fix a series of AT commands in a configuration file. When a mobile application requests a AT command, the analog device finds the corresponding information in the configuration file according to the requested AT command. Entry will then be A stipulated response is sent to the mobile app. This analog-like AT command requires TE support to be analogous to AT-command network-side behavior and consumes a lot of hardware costs. Moreover, the traditional analogy method can only compare and judge an entire AT command, and cannot parse the internal parameters of the AT command, resulting in low analogity flexibility.

In view of the above, it is necessary to provide a system and method for analog phone AT command test, which can effectively compare the network side behavior of the mobile phone AT command.

A system similar to the mobile phone AT command test, the system running on a computer, the computer includes a mobile phone application to be tested, and an AT script document for testing the AT command, the system includes: a read module for Reading an AT state in the AT script document; executing an module, configured to determine whether the AT state is an actively requested AT state or an inactively requested AT state, and if the AT state is an inactively requested AT state, the performing The module executes the content in the AT state of the inactive request. If the AT state is an actively requested AT state, the execution module waits for an AT command request of the mobile application, and the communication module is configured to receive the sending from the mobile application. An AT command request; a request management module, configured to receive an AT command request sent by the communication module, and convert the AT command request into an environment variable identified by the AT script document; the execution module is further configured to perform the conversion according to the a subsequent AT command requesting execution of the AT state of the active request, generating an AT command response requested by the AT command; and the communication module is further configured to respond to the AT command Feedback to the mobile app.

A method for analog phone AT command testing, the method being applied to a computer, the method comprising the steps of: (a) reading an AT state in an AT script document; (b) if the AT state is an inactive request state, Executing the content in the AT state of the inactive request; (c) waiting for the mobile phone application if the AT state is the actively requested AT state The program sends an AT command request; (d) receives an AT command request sent by the mobile phone application, converts the AT command request into an environment variable identified by the AT script document; (e) executes the initiative according to the converted AT command request The requested AT state, generating an AT command response requested by the AT command; and (f) feeding back the AT command response to the mobile application.

1 is a block diagram of a preferred embodiment of a system for analog AT-command testing of the present invention.

2 is a flow chart of a method of a preferred embodiment of the method for testing AT-like mobile phone commands of the present invention.

As shown in FIG. 1, it is an architectural diagram of a preferred embodiment of the system of the present invention analog phone AT command test. The system 100 of the analog AT test runs on the computer 1. The computer 1 further includes a mobile phone application 101. In the preferred embodiment, the mobile application 101 refers to a short message, a telephone control program, and the like. The mobile phone application 101 sends an AT command request to the system 100 that is analogous to the AT command test, the AT command request including a send SMS request, a call request, and the like.

The system 100 of the analog AT command test stores an AT script document for testing an AT command. In the preferred embodiment, the AT script document is described by an Extensible Markup Language (XML).

The AT script document is composed of a plurality of AT states, and an AT state includes a completion one. All necessary information requested by the secondary AT command, including all necessary information required for the active request, the inactive request, and the intermediate response. The AT state is divided into an active request AT state and an inactive request AT state, and the AT state belonging to the active request is only executed when the mobile phone application 101 issues an AT command, and the AT state belongs to the inactive request. , will be executed without triggering the request from the mobile app.

The AT state is composed of a plurality of nodes, and the determination of the content of the AT command request response and the state logic are completed through these nodes, thereby responding to the request of the AT command. The node identifies the start and end through a specific tag. For example, the label STATE represents the AT status identification node, the RESPONSE represents the response node, and the IF represents the judgment node.

Each mobile application 101 corresponds to a script document, and the plurality of mobile applications 101 can also correspond to a script document. The AT script document includes a script file corresponding to the AT command request and a script file corresponding to the AT command request.

The system 100 of the analog AT command test includes a plurality of functional modules to perform the test of the analog AT command. The module is a software program having a specific function, and the software is stored in a computer readable storage medium or other storage device and can be executed by a computer or other computing device including the processor. The analog 100 command test system 100 includes a read module 10, an execution module 12, a communication module 14, and a request management module 16.

The reading module 10 is configured for the mobile phone application to read an AT state in the AT script document, and store the read AT state and the node included in the AT state in a data structure of the linked list tree. The reading module 10 is further configured to determine whether there is an AT state that has not been read in the AT script document. If there is an AT state that is not read in the AT script document, the next AT state is read.

The execution module 12 is configured to acquire an AT state from the data structure of the linked list tree and execute the AT state. When the execution module 12 completes an AT state, the next AT state is obtained from the linked list tree. The execution of the AT state refers to a process in which the execution module 12 generates an AT command response according to a tag in the AT script by interpreting the node described in the AT script.

The execution module 12 is further configured to determine whether the acquired AT state is an actively requested AT state or an inactively requested AT state. If the acquired AT state is an AT state that is not actively requested, the execution module 12 immediately executes the content in the AT state. If the acquired AT state is an actively requested AT state, the execution module 12 waits for an AT command request from the mobile phone application 101.

The communication module 14 completes the underlying communication with the mobile phone application 101, that is, receives the AT command request sent from the mobile phone application 101, and sends the AT command request to the request management module 16; the receiving from the execution module 12 The AT command responds and sends it to the mobile app 101. The communication module 14 can receive one or more rows of AT command requests at a time, and send the AT command request to the request management module 16 line by line or send the AT command response to the mobile phone application 101 line by line.

The request management module 16 is configured to create a queue in the memory, request the AT command to be placed into one end of the queue for an array unit according to an AT command, and use the same size queue unit from the The other end of the queue reads an AT command request. After the AT command request is read, it will be deleted from the queue.

The request management module 16 converts the AT command request into an environment variable identified by the AT script document after reading an AT command request from the queue. In the preferred embodiment, the format of the environment variable of the AT script document is % plus a positive integer. For example, if the request management module 16 sets a command from one of the AT command requests obtained from the queue Let: ATCMD=P1, P2, P3, where ATCMD is the command name, “=” is the glyph of the set command, “P1”, “P2” and “P3” are the set parameters, “,” is the parameter. Separation symbol. The command name is converted to an environment variable corresponding to "%0", and the parameters "P1", "P2", and "P3" are converted to environment variables and respectively correspond to "%1", "%2", and "%3".

The request management module 16 is further configured to determine whether the converted AT command request corresponds to the content of the AT state. If the content of the current AT state is a script document for making a call, but the converted AT command requests a request for sending a short message, the result of the request management module 16 determining is the converted AT command request and the AT state. The content does not correspond.

The communication module 14 is further configured to: when the result of the determination is that the converted AT command request does not correspond to the content of the AT state, send the prompt error information to the mobile phone application 101, and notify that the mobile phone application 101 cannot be returned.

When the result of the determination is that the converted AT command request corresponds to the content of the AT state, the execution module 12 executes the content of the AT state, generates an AT command response requested by the AT command, and generates the AT command. The response is sent to the communication module 14, and the communication module 14 feeds back the AT command response to the mobile phone application 101.

As shown in FIG. 2, it is a flowchart of a method for a preferred embodiment of the method for testing an AT analog command of the present invention.

In step S30, the reading module 10 reads an AT state in the AT script document, and stores the read AT state and the node included in the AT state in the data structure of the linked list tree.

Step S31, the execution module 12 acquires an AT shape from the data structure of the linked list tree. State, determine whether the AT state is an actively requested AT state or an inactively requested AT state. If the read AT state is the AT state of the inactive request, the process proceeds to step S32; if the read AT state is the actively requested AT state, the process proceeds to step S34.

In step S32, the execution module 12 executes the content in the AT state of the inactive request, and proceeds to step S33.

In step S33, the reading module 10 determines whether there is an AT state that has not been read in the AT script document. If the AT state in the AT script document has been read, the process ends. If there is an AT state that is not read in the AT script document, the process goes to step S30.

In step S34, the communication module 14 receives the AT command request sent by the mobile phone application 101, and the request management module 16 places the received AT command request into one end of the queue created by the request management module 16.

In step S35, the request management module 16 acquires an AT command request from the other end of the queue, and converts the AT command request into an environment variable identified by the AT script document. In the preferred embodiment, the format of the environment variable of the AT script document is % plus a positive integer. For example, if the request management module 16 selects one of the AT command requests obtained from the queue: ATCMD=P1, P2, P3, where ATCMD is the command name, and “=” is the flag of the set command. Symbols, "P1", "P2" and "P3" are the parameters set, and "," is the parameter separator. The command name is converted to an environment variable corresponding to "%0", and the parameters "P1", "P2", and "P3" are converted to environment variables and respectively correspond to "%1", "%2", and "%3".

In step S36, the request management module 16 determines whether the converted AT command request corresponds to the content of the actively requested AT state. If the current AT status is dialed If the converted AT command requests a request to send a short message, the request management module 16 determines that the converted AT command request does not correspond to the content of the AT state, and directly enters the step. S37. If the converted AT command request corresponds to the content of the AT state, the process proceeds to step S38.

In step S37, the communication module 14 sends a prompt error message to the mobile phone application 101, notifying that the mobile phone application 101 cannot be returned, and proceeds to step S35 to execute the next AT command request.

In step S38, the execution module 12 executes the content of the AT status of the active request, generates an AT command response requested by the AT command, and sends the AT command response to the communication module 14.

In step S39, the communication module 14 feeds back the AT command response to the mobile phone application 101, and proceeds to step S33.

It should be noted that there is no sequence between the above steps S30 to S32 and the steps S34 to S35, and the processes of the steps S30 to S32 are independent of the processes of the steps S34 to S35.

The above is only the preferred embodiment of the present invention, and has been used in a wide range of applications. Any other equivalent changes or modifications which are not departing from the spirit of the present invention should be included in the following claims. Inside.
