The character " / " generally indicates that the associated objects are in an "or" relationship.

[0057] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0058] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0059] The embodiments of the present application provide a test case generation method and device, which can reduce the difficulty of writing protocol test cases and improve the efficiency of writing protocol test cases.

[0060] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0061] The technical solutions provided in the embodiments of the present application can be applicable to a variety of systems, such as 5G systems or 6G systems. For example, applicable systems may be global system of mobile communication (GSM) systems, code division multiple access (CDMA) systems, wideband code division multiple access (WCDMA) general packet radio service (GPRS) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, long term evolution advanced (LTE-A) systems, universal mobile telecommunication systems (UMTS), worldwide interoperability for microwave access (WiMAX) systems, 5G new air interface (NR) systems, etc. These various systems include terminal devices and network devices. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0062] Figure 1 This is one of the structural diagrams of the test case generation device provided in the embodiment of the present application, such as Figure 1 As shown, the test case generation device includes: a code stream parsing module 101, a display module 102 and a test case generation module 103, wherein:

[0063] The code stream parsing module 101 is used to decode the air interface message code stream to obtain a structure tree; convert the air interface message code stream from the structure tree into a template recognized by the Test and Test Control Notation (TTCN3) language;

[0064] The display module 102 is used to display the template in a display area and receive input operations, wherein the input operations are used to modify parameters in the template to obtain a modified template;

[0065] The use case generation module 103 is used to generate a protocol test case according to the modified template.

[0066] The test case generation device provided in the embodiment of the present application inputs an air interface message code stream and calls a code stream parsing module to decode the air interface message code stream to obtain a structure tree. The user can directly read the message content through the interface without having to fill in each IE one by one, which can simplify the message processing method. The air interface message code stream is then converted from the structure tree into a template recognized by the TTCN3 language. In response to the input operation, the parameters in the template are modified in the display area to obtain the modified template; the use case generation module is called to generate a protocol test case according to the modified template, thereby reducing the difficulty of writing protocol test cases and improving the efficiency of writing protocol test cases.

[0067] In some embodiments, an initial value of at least one tree node in the structure tree is determined by a parameter value corresponding to the air interface message code stream.

[0068] Figure 2 This is a flow chart of a test case generation method provided by an embodiment of the present application, which is applied to a test case generation device, such as Figure 2 As shown, the method includes steps 201 to 204, wherein:

[0069] Step 201: Call the code stream parsing module to decode the air interface message code stream to obtain a structure tree.

[0070] It should be noted that the message type corresponding to the air interface message code stream is the same as the message type of the protocol test case. For example, the code stream parsing module is called to decode the air interface message code stream input by the user to obtain a visual structure tree. The structure tree here refers to the tree structure of Abstract Syntax Notation One (ASN.1). The root node of the structure tree is the air interface message name, and each child node is obtained by disassembling the air interface message structure. The code stream parsing module decodes the air interface message code stream based on the ASN.1 document and code stream editing rules. The ASN.1 document is used to convert the air interface message structure into the ASN.1 structure.

[0071] Optionally, a structure tree is displayed in the display area, with different tree nodes corresponding to different parameters of the protocol test case. The initial value of at least one tree node in the structure tree is determined by the parameter value corresponding to the air interface message code stream. Users can directly read the message content through the interface without having to fill in each IE, which simplifies message processing.

[0072] Step 202: Convert the air interface message code stream from the structure tree into a template recognized by the TTCN3 language.

[0073] The template recognized by the TTCN-3 language is a special data structure used to carry sent messages and match received messages in protocol conformance testing.

[0074] For example, an object-oriented programming language (Csharp) module is called to convert the air interface message code stream from a structure tree into a template recognized by the TTCN language.

[0075] Step 203: In response to the input operation, modify the parameters in the template in the display area to obtain a modified template.

[0076] Step 204: Call the use case generation module to generate a protocol test case according to the modified template.

[0077] Specifically, the modified template is used to generate a test body, which is the main part of the test case and can include multiple steps. The use case generation module is called to construct a protocol test case based on the test body, completing the use case writing.

[0078] In the test case generation method provided in the embodiment of the present application, an air interface message code stream is input, and a code stream parsing module is called to decode the air interface message code stream to obtain a structure tree. The user can directly read the message content through the interface without the user having to fill in each IE one by one, which can simplify the message processing method. The air interface message code stream is then converted from the structure tree into a template recognized by the TTCN3 language. In response to the input operation, the parameters in the template are modified in the display area to obtain the modified template; the use case generation module is called to generate a protocol test case according to the modified template, thereby reducing the difficulty of writing protocol test cases and improving the efficiency of writing protocol test cases.

[0079] Optionally, according to the selection operation, the message type of the air interface message code stream is determined; the message type includes at least one of a system information block (SIB) message, a radio resource control (RRC) message and a non-access stratum (NAS) message.

[0080] Optionally, when the message type of the air interface message code stream is a SIB message or an RRC message, an ASN.1 encoding and decoding tool is called to parse the air interface message code stream into an ASN.1 hierarchical structure format; and the ASN.1 hierarchical structure format is converted into a template recognized by the TTCN3 language.

[0081] Optionally, in the case where the message type of the air interface message code stream is a SIB message, according to the first protocol rule corresponding to the SIB message, the configurable content in the air interface message code stream is presented in the form of a first default value through a template identified by the TTCN3 language. Here, the SIB message takes SIB1 as an example, and the first protocol rule is, for example, the structure definition content recorded in Chapter 6 of the 3GPP 5G standard protocol TS 38.331. The template will present the configurable content of SIB1 in the form of the default value agreed in Chapter 4.6 of the protocol TS38.508-1 in accordance with the structure definition content of the protocol TS 38.331, and the user can modify and fill in the corresponding configuration parameters as needed.

[0082] Alternatively, when the message type of the air interface message code stream is an RRC message, the configurable content in the air interface message code stream is presented as a second default value using a template identified by the TTCN3 language according to a second protocol rule corresponding to the RRC message. The second protocol rule corresponding to the RRC message herein is, for example, the structure definition content described in Section 6 of the 3GPP 5G standard protocol TS 38.331. The template presents the RRC configurable content as the default value specified in Section 4.6 of the protocol TS 38.508-1 according to the structure definition content of the protocol TS 38.331, and the user can modify and fill in the corresponding configuration parameters as needed.

[0083] Optionally, in the case where there are multiple NAS message templates, the multiple NAS message templates are included in the RRC message template; or, different NAS message templates are displayed at the same level.

[0084] In this application, the test case generation device supports two input methods: code stream and template. A template is a template supported (recognized) by TTCN3 syntax, such as a TTCN3 code template. The template input parameters are control elements configured in the SDT interface. The template is filled in with the input parameters to generate the corresponding TTCN3 code. The template is pre-acquired. The content of the air interface message is input in both code stream and template modes and can be presented in the display area. Figure 3 is a schematic diagram of the code stream input provided by the embodiment of the present application, Figure 4 This is a schematic diagram of test case generation and message sending and receiving provided by the embodiment of the present application, such as Figure 3 and Figure 4 As shown, for code stream input, the message content is entered through the interface. The background tool will obtain the interface value, automatically generate code that complies with the TTCN-3 specification, and finally encapsulate and send the message according to the specification. This application mainly introduces code stream input.

[0085] (1) The display area of the test case generator, also known as the script editing area. Here, users edit the test case flow and message content in the script editing area through the interface. The test case generator generates TTCN code from the message content by calling other modules and saves it as an executable file.

[0086] (2) Air interface message input.

[0087] In the script editing area, users select the air interface message input box and configure SIB messages, RRC messages, or NAS messages as needed. There are two configuration methods: template input, which allows users to directly view the message structure and parameters. However, the large number of information elements (IEs) required to be filled in can be time-consuming for users unfamiliar with the protocol. Stream input: In this interface module, users enter the corresponding message stream and click the decode button to display a visual structure tree, showing the parameters required for the test case.

[0088] (3) The code stream parsing module, also known as the code stream conversion tool, is used to convert the code stream into a template. The code stream conversion tool includes RRC code stream and NAS code stream parsing functions, and finally parses the code stream into a template format. The RRC code stream uses open source tools (OSS) (ASN.1 encoding and decoding tools) to parse the code stream into the ASN.1 hierarchical structure format, and then uses the object-oriented programming language (Csharp) to convert it into the template used by the TTCN language.

[0089] In the existing technology, NAS code streams are generally parsed by calling external functions, which requires manual coding and line-by-line adaptation, making the operation complex. To address this problem, this application uses a code stream conversion tool to convert the code stream into a template form and fill it into the test case body, thereby improving the efficiency of use case writing.

[0090] Figure 5 This is a schematic diagram of the principle of the code stream parsing module provided in the embodiment of the present application. Figure 5 As shown in the figure. For NAS stream conversion process:

[0091] a. Obtain NAS stream: Obtain the message stream from the live network or log. This stream can be obtained from the terminal or instrument monitoring tool. The obtained stream will be used in step e.

[0092] b. Create an ASN.1 file: Refer to 5G protocol 25.501 and convert the NAS message structure defined by 3GPP into the corresponding ASN.1 definition structure using the spreadsheet editing tool Excel according to the rules defined by the ASN.1 syntax, and generate the corresponding document.

[0093] c. Add rules and grammar: According to the protocol specification, define the encoding and decoding rules of the bitstream for the characteristic structure type. For example:

[0094] Syntax: sign ""

[0095] This syntax is used to mark a leaf node and add a code to the leaf node. The code is lowercase English letters. Among them, t and l are only used when the leaf node belongs to the iei or iel attribute but the name is not iei or iel.

[0096] This tag is auxiliary information and is used in subsequent execution of other grammars. After completing the parsing at this level, this information can be discarded.

[0097] Syntax: Format()

[0098] This syntax is used to indicate whether the iei and iel types appear in the current node structure. Format(t) indicates that iei appears but iel does not appear. Format(l) indicates that iei does not appear but iel appears. Format(tl) indicates that both appear.

[0099] This information can be discarded after the current structure has finished parsing.

[0100] Syntax: Choice(XXXX), ChoiceId"XXXX"O, ChoiceId"XXXX"B (XXXX is the option value, "XXXX"O is the hexadecimal option ID, and "XXXX"B is the binary option ID).

[0101] This syntax is used to determine the selection result of an option, and the selection result is determined by whether the option value is equal to the option ID.

[0102] d. Csharp encoding and decoding module: Import the ASN.1 document generated in step b into the Csharp software, then define the interface file based on the newly added encoding and decoding rules and syntax, develop the corresponding implementation code, and encapsulate it into a code stream encoding and decoding module, which can be called on other tools or software.

[0103] e. Generate a structure tree: Enter the code stream obtained in step a in the script editing area, call the Csharp encoding and decoding module, and use the decoding function to output the ASN.1 structure tree.

[0104] f. Convert to template: Call the Csharp conversion module to convert the structure tree into a template recognized by the TTCN language.

[0105] g. Embed use cases: By calling the SDT background code writing module, fill the template into the use case test body, construct the test case, and complete the use case writing.

[0106] (4) Template input.

[0107] The template carries the content of the air interface message and has a complex structure. It is processed according to the following three categories:

[0108] (a) SIB message. Taking SIB1 as an example, the template will present the configurable content of SIB1 as default values in accordance with the provisions of the 38.331 protocol. Users can modify and fill in the corresponding configuration parameters according to their needs.

[0109] (b) RRC message. Taking LTE RRC Reconfiguration as an example, the template will present the configurable content as default values in accordance with the provisions of the 36.331 protocol, so that users can intuitively see the configurable IE.

[0110] (c) NAS messages are divided into two scenarios, in which multiple NAS message templates will appear. Figure 6 This is a schematic diagram of a NAS message presentation method provided in an embodiment of the present application, such as Figure 6 This application designs the NAS message presentation method as a template for multiple NAS messages to be displayed at the same level, and users can adjust it according to their needs:

[0111] Scenario 1: The NAS message is included in the RRC message.

[0112] Scenario 2: The NAS message is included in the NAS message.

[0113] (5) Use case generation module, also known as the background code generation tool. The use case generation module obtains the modified template from the display area, saves it, and automatically encapsulates it according to the TTCN-3 format to generate the corresponding SIB message, RRC message, or NAS message.

[0114] (6)Message sending.

[0115] Send the message according to the TTCN-3 format and the configured time.

[0116] The test case generation method provided in the embodiments of this application can be used in protocol testing, simplifying message processing and reducing the difficulty of test case writing. By writing TTCN-3-style test cases, a user interface can be displayed and streamed, invoking the stream parsing module to convert NAS streams. This allows for direct reading of message content through the interface and streamed input. This provides increased flexibility and simplifies the test case writing process, making it easier to get started.

[0117] Figure 7 This is the second structural diagram of the test case generation device provided in the embodiment of the present application, such as Figure 7 As shown, the test case generation device includes a memory 720, a transceiver 700, and a processor 710, wherein:
