[0047] Each network element device in the 5G core network needs to undergo comprehensive functional and performance testing before the equipment supplier releases a version or an updated version is deployed on the live network.

[0048] At present, the testing of 5G core network requires the purchase of hardware testers to simulate network elements and test various protocol processes, or directly access real network element devices and use actual mobile phones to test various processes and services. Testers are generally devices manufactured by tester manufacturers based on their hardware platforms. Users can only simulate certain network element simulation tests based on the functional characteristics they support, and cannot be controlled independently, and cannot perform customized tests according to their own business requirements. In addition, each test step requires manual configuration and operation of the test instrument, and the test process and results also require manual intervention throughout the process, which cannot achieve automation to reduce labor costs.

[0049] Based on this, an embodiment of the present application provides a network element testing method for a 5G network. Operators or core network equipment developers can use this automated testing method to write their own test cases for all services on a virtualized platform to perform simulation tests on core network elements, and support automated operations, which can achieve and exceed the functions of hardware test instruments.

Specifically, several simulated network elements that interact with the network elements under test are established through the test script, and the message interaction between the above-mentioned simulated network elements and the network elements under test is simulated through the interface protocol. The embodiments of the present application can also perform accuracy verification on the sent messages or received messages. If the accuracy verification fails, the test result is abnormal. Alternatively, if an error occurs at any node during the information interaction process, the test result is abnormal. The test method provided in the present application can be used for various network elements of the 5G core network, including AMF, SMF, PCF, CHF, UPF, UDM, NRF, AUSF, etc.

[0056] Optionally, in one embodiment of the present invention, the method further comprises:

[0057] Establish a network element test architecture for 5G networks, including:

[0058] A communication module, used to simulate several simulated network elements connected to the network element under test, and to perform sending, receiving, transferring, encoding and decoding processing on the message;

[0059] The script module is used to establish surround test logic for simulating the plurality of simulated network elements, and to simulate the behaviors of the sessions of the plurality of simulated network elements on the interface.

[0060] In some possible implementations, the present application embodiment is as follows Figure 2 The architecture shown manages the test network elements and test processes during the 5G test process to achieve automated testing.

[0061] Optionally, in an embodiment of the present invention, the performing information interaction with the network element under test through an interface corresponding to the simulated network element and receiving or sending a message includes:

[0066] In some possible implementations, the present application does not limit the specific type of the network element under test, and those skilled in the art may set the specific types of the network element under test and the simulated network element according to test requirements.

[0076] In some possible implementations, the interactive interface in the embodiment of the present application can be in various forms. At the same time, the interactive interface can be in any layout, and the present application does not limit the specific form of expression of the interactive interface. Similarly, for the establishment of a test script through an interactive interface, it can be a conventional programming method or a graphical operation interface, which is convenient for testers to establish test scripts through simple methods such as dragging and copying, reducing the restrictions on the programming skills of testers. It is understandable that the trigger operation in the present application can be a mouse operation such as clicking, dragging, and selecting, or a keyboard operation, and of course, any feasible operation. The trigger operation can represent a selection or a configuration. By configuring the test script through an interactive interface, the message model, the interactive flow of messages, the test flow, the test-related parameters, etc. in the test script can be configured, and then a test script is formed to realize automated testing.

[0083] In summary, the method provided in the embodiment of the present application includes: simulating several simulated network elements connected to the network element under test through a script; exchanging information with the network element under test through an interface corresponding to the simulated network element, and receiving or sending a message; verifying the accuracy of the message, or verifying the message sending and receiving process, and determining the test result according to the verification result. The embodiment of the present application can realize automated testing by simulating the sending and receiving messages and the sending and receiving process during the test through a script, which is conducive to improving the test efficiency.

[0084] Below, refer to Figure 3 The specific embodiment shown is used to introduce the test method provided by this application in detail:

[0085] Taking the core network element SMF as an example, the main network elements connected to the outside of the core network are AMF, PCF, and UPF, and the corresponding interfaces are N11, N7, and N4 interfaces. This test solution simulates AMF, PCF, and UPF (i.e., the simulated network elements in the application) through software, implements the protocol flow of their N11, N7, and N4 interfaces (i.e., the first interface, the second interface, and the third interface in this application), and performs surround testing on the network elements to verify that the functions of SMF comply with the protocol specifications.

[0086] This test solution is based on the Linux operating system, traditional X86 or ARM general-purpose servers and IP networks, and uses software scripting to simulate AMF, PCF and UPF, and automatically interacts with SMF to send and receive messages on the N11, N7, and N4 interfaces. The correctness of the messages and the correctness of the process are verified in the script, thereby achieving the purpose of verifying the SMF process function.

[0087] The simulation test tool is divided into three modules:

[0088] Test core communication module: This module mainly implements several interface protocols such as N11, N7, N4, etc. that communicate with SMF, and is used to simulate several network elements surrounding SMF. This module only performs message sending, receiving, transiting, encoding and decoding, and does not parse and process message services and processes. Messages received from the SMF interface will be forwarded to the corresponding script after decoding, and messages received from the script will be forwarded to SMF from the corresponding interface after encoding.

[0089] Test script function module: This module implements the logic of simulating network elements to perform surround testing on SMF. The script simulates the behavior of the sessions of the AMF / PCF / UPF network elements on each interface, and SMF will think that it is connected to the real network element.

[0090] Take the mobile phone online test as an example, write a test script, refer to Figure 2 As shown, the main process of the test script is as follows:

[0091] The first step is to send a text-defined create session request message to the communication module. The communication module encodes and sends it to SMF through the N11 interface simulating AMF①;

[0092] Step 2: On the simulated N7 interface, the communication module receives a request message from the SMF requesting the PCF to create a session②. The communication module decodes the message and forwards it to the test script. The test script processes the message and returns a response message to the communication module. The communication module then sends the encoded response message to the SMF from the N7 interface③.

[0093] Step 3: On the simulated N4 interface, the communication module receives a request message from the SMF requesting the UPF to create a session④. The communication module decodes the message and forwards it to the test script. After processing, the test script returns a response message to the communication module. The communication module then sends the encoded response message from N4 to the SMF⑤.

[0094] In the fourth step, on the simulated N11 interface, the communication module receives the create session response message⑥ sent by the SMF. The communication module decodes the message and forwards it to the test script. The test script checks and confirms that the message is correct, and the test process is considered to have ended correctly.

[0095] If any test message or process fails, the test script can detect and report the error.

[0096] Test tool management module: This module is mainly responsible for configuring and running the core communication module and all test scripts, supporting automated operations, and collecting statistics on test reports.

[0097] In some embodiments, the present application can implement a custom test process, and the test core communication module generally does not need to be updated after completion.

[0098] When you need to test a new service in the core network, for example, if SMF implements a new function, you can add some message definitions to some messages sent and received. At this time, you can add a test script to simulate the network elements connected to SMF, and also support the definition and process processing of these message definitions. Based on the message exchange with SMF, you can verify whether SMF carries these message contents according to the protocol function and whether the process conforms to the new function definition. The output results obtained by running the script can complete the test verification of this new function of SMF.

[0099] In some embodiments, the present application can realize automated testing. The management module of the test tool can automatically run all test cases, complete the testing of all functional items, automatically collect test results and output reports through pre-configuration, without manual intervention and operation. The test cases required by the user are stored in the form of script files or in a database, and each test script can support one or more test cases.

[0100] The management module is responsible for managing test cases and providing an interactive interface with the user, including command line mode and graphical interface mode. The management module provides the following configurations:

[0101] Configuring the communication interface with the network element:

[0102] Configure each interface of the network element under test, including IP address, port number, and various attribute configurations required by the interface;

[0103] Configure the service IP / port number of the communication module and the service IP / port number of the script;

[0104] Test case and test process management configuration:

[0105] On the interface, you can select the test cases (multiple) to be run and the running mode (serial or parallel);

[0106] Configure the test interval, number of failed attempts, and number of test cycles;

[0107] Test message configuration:

[0108] Users can predefine the message to be sent, edit and save it in text format. After the test case reads the message definition, it uses the message as a template to generate a message to be sent.

[0109] Alarm management configuration:

[0110] Set the alarm level and alarm items, including the following:

[0111] Network link interruption alarm;

[0112] CPU overload alarm;

[0113] Test script failure alarm;

[0114] Failure rate alarm;

[0115] Notification management configuration:

[0116] The test status results can be proactively notified to multiple users in real time via email, SMS, WeChat, and various mobile apps, such as test progress, test results, and alarm information.

[0117] The testing process is as follows:

[0118] 1. The user configures the interfaces on the test tool side and the network element under test side respectively;

[0119] 2. The user selects the test cases to be run and arranges the order of the test cases;

[0120] 3. The user configures the test message template and test process (serial or parallel) required by the test case;

[0121] 4. The user configures the alarm level and the email address, mobile phone number, WeChat ID and other information to receive test result notifications;

[0122] 5. Click Start in the graphical interface or type a command in the command line to start the test;

[0123] 6. The test script is loaded and automatically executed, and the test results are summarized to the management module in real time;

[0124] 7. The management module notifies users via email, SMS, WeChat, etc. according to the configuration;

[0125] 8 Users can also check the test progress, test status, and test results at any time in the management module.

[0126] It can be seen that the embodiment of the present application implements a simulation enclosure test of a core network element on a general server; the simulation network element test tool is designed to be divided into a communication core module and a test script business processing module; the test tool adopts an implementation mechanism that separates the communication core module and the specific test business script module; the communication core module is independent of the test business and is only responsible for creating and maintaining the basic link and encoding and decoding of the interface, and transferring business messages; the communication core module and the test script communicate via TCP / IP to encapsulate the messages that need to be transferred; the test script can arbitrarily edit and verify the test success conditions as needed to verify various 5G business process steps; the test script constructs 3GPP-defined messages in text format, and flexibly fills in the message content in text format to support respective test business scenarios; to implement a new test case, it is only necessary to fill in the sent message content with text in the test script, determine the received text message content, and verify whether the message flow is correct, without modifying the communication core module code; the test script can use a pre-defined message template to generate and send the tested message; the test script can use The pre-defined message template is compared with the message sent by the network element to determine whether it is correct; the test script is implemented in a general scripting language, including but not limited to Python, Perl, Ruby, Tcl, etc.; the test script is stored in a script file or database, and each test script can contain one or more test cases; the script can be automatically run and verify the test results according to user needs, covering all test scenarios and use cases without manual intervention; there is no limit on the number and scenario of test scripts, and users can continuously add new test scripts to implement various new 5G business tests; the method of automatic script operation can be run in serial mode, executing one script before executing the next one; the method of automatic script operation can also be run in parallel, with all scripts executing concurrently at the same time; after the user starts the test, the test script automatically runs and interacts with the network element under test to execute the test steps without manual intervention; the test script operation results are automatically collected and presented to the user through the management module; the automated test results can be notified to customers via email, SMS, WeChat, and mobile app.

[0127] The embodiments of the present application do not require the purchase of dedicated test instruments to simulate and test core network elements. They utilize existing general-purpose servers based on the Linux operating system and IP network, and do not require dedicated hardware and equipment. Test cases can be flexibly defined and expanded as needed to support various new business tests. Automated testing can be achieved without the need for manual test execution one by one.
