[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] Please see below. Figure 1 , Figure 1 This is a flowchart illustrating a conformance testing method for a network layer protocol provided in an embodiment of this application.

[0047] Specific steps may include:

[0048] S101: Determine multiple test items of the network layer protocol under test based on the network layer function, and set a corresponding logical topology diagram for the test items;

[0049] This embodiment can be applied to a computer connected to the device under test and the testing equipment. The computer runs host computer software, which can implement the consistency testing scheme provided in this embodiment.

[0050] The device under test and the test equipment are connected to the wireless channel simulator via RF feed lines. The protocol stack running on the test equipment contains a preset network layer protocol that has passed the conformance test, and the protocol stack running on the device under test contains the network layer protocol under test.

[0051] The aforementioned test equipment and the device under test are both wireless broadband self-organizing network devices used for emergency command (i.e., emergency command wireless broadband self-organizing network devices). Both the preset network layer protocol and the network layer protocol under test are protocols used in wireless broadband self-organizing networks for emergency command. Prior to this step, the relevant standards for the aforementioned wireless broadband self-organizing network used for emergency command (i.e., emergency command wireless broadband self-organizing network standards) can be determined. The preset network layer protocol is a network layer protocol that conforms to the aforementioned relevant standards, and the network layer protocol under test is the network layer protocol set by the manufacturer of the device under test according to the aforementioned relevant standards.

[0052] This embodiment can determine multiple test items of the network layer protocol under test based on the network layer functions, which are as follows:

[0053] Link maintenance function: The network layer needs to monitor the link status between this node and its neighboring nodes in real time, determine the link availability (connected or disconnected), update the routes in a timely manner, and keep the routing information of the entire network valid in real time.

[0054] Routing management function: In order to achieve end-to-end communication between all nodes in an ad hoc network, the routing function needs to be performed by ordinary nodes in the network, rather than by a separate dedicated routing device (such as a router). Therefore, each network node is required to have the ad hoc network multi-hop routing forwarding function, which is implemented by the network layer.

[0055] Data processing functions: Data processing at the network layer mainly includes two parts: data routing and data encapsulation / decapsulation. The network layer receives multiple data streams from the local application or other application nodes. The next-hop transmission paths for different unicast and broadcast / multicast data streams are different. Unicast data streams confirm the next-hop node by querying the routing table, while multicast and broadcast data use flooding protocols to broadcast data in order to avoid broadcast storms.

[0056] Each test item can include multiple test sub-items, and each test item or test sub-item can have its corresponding logical topology diagram. The logical topology diagram described above is used to describe the logical connection relationship between the test equipment and the device under test.

[0057] S102: Send a control command to the wireless channel simulator according to the logical topology diagram, so that the wireless channel simulator adjusts the logical connection relationship between the test device and the device under test;

[0058] Prior to this step, there may be an operation to determine the test item that needs to be executed, and then a control command is sent to the wireless channel simulator according to the logical topology diagram of the test item to be executed, so as to establish a logical connection relationship that conforms to the test item to be executed.

[0059] S103: Based on the logical topology diagram, perform the test operation corresponding to the test item on the test equipment and the device under test;

[0060] After setting up the logical connection relationships, the test operation corresponding to the test item to be executed can be performed on the test device and the device under test based on the logical connection relationships of the logical topology diagram of the test item to be executed.

[0061] The test result of the above test operation can be either a pass or a fail. If the test result is a fail, proceed to S104. If the test result is a pass, it can be determined whether all test items have been tested. If all have been tested, proceed to S105. If not all have been tested, repeat the operations of S102 and S103.

[0062] S104: The tested network layer protocol is determined to have failed the consistency test;

[0063] S105: If the test results of all the items to be tested are all passed, then the network layer protocol under test is determined to have passed the consistency test.

[0064] If all test items are completed and all test results are passed, it can be determined that the network layer protocol in the device under test conforms to the relevant standards for wireless broadband self-organizing networks used for emergency command and has passed the conformity test.

[0065] In this embodiment, both the device under test (DUT) and the testing device are connected to a computer, and both are connected to a wireless channel emulator via RF feeders. This embodiment determines multiple test items for the network layer protocol under test based on the network layer's functionality, and sends control commands to the wireless channel emulator before testing each test item to adjust the logical connection between the testing device and the DUT. After the test operation, if the test result is a failure, the network layer protocol under test is deemed to have failed the conformance test; if all test items pass, the network layer protocol under test is deemed to have passed the conformance test. This embodiment can perform conformance testing on the network layer protocol in an emergency command wireless broadband self-organizing network, ensuring interoperability between emergency command wireless broadband self-organizing network devices from different manufacturers.

[0066] The process described in the above embodiments is illustrated below through examples in practical applications.

[0067] This embodiment discloses a consistency testing method for network layer protocols in emergency command wireless broadband self-organizing networks. It can test the consistency of network layer protocols developed by different manufacturers according to the "Emergency Command Wireless Broadband Self-Organizing Network Standard Specification - Network Layer" standard, and verify whether the network layer protocol implementations of different manufacturers are consistent with the standard specifications. This plays a very important role in ensuring the interconnection and interoperability of emergency command communication wireless broadband self-organizing network equipment independently developed by different manufacturers.

[0068] This embodiment discloses a conformance testing method for network layer protocols of wireless broadband ad hoc networks for emergency command communication. It covers all functional tests of network layer protocols and does not require any modification to the device under test, making it convenient and feasible.

[0069] The items to be tested may include link maintenance function testing, routing management function testing, and data processing function testing.

[0070] The link maintenance function test includes the following sub-items: link layer detection link maintenance function sub-test and network layer detection link maintenance function sub-test. The routing management function test includes the following sub-items: route entry creation function sub-test, route entry update function sub-test-1, route entry update function sub-test-2, route entry update function sub-test-3, route entry update function sub-test-4, route entry update function sub-test-5, route entry deletion function sub-test-1, and route entry deletion function sub-test-2. The data processing function test includes the following sub-items: unicast service transmission function sub-test, unicast service reception function sub-test, multicast service transmission function sub-test, multicast service reception function sub-test, multicast service transmission function sub-test, and multicast service reception function sub-test. After all the above tests are completed, the test results can be checked. If any sub-test fails, the tested network layer protocol is deemed to have failed the test. In this case, the vendor under test is notified to rectify the issues based on the test results, and then all tests are re-executed. Only when all tests pass can the conclusion be drawn that the tested network layer protocol has passed the conformance test.

[0071] The detailed test results and conclusions generated during the testing process are summarized into a test report for easy reference.

[0072] Please see Figure 2 , Figure 2 This application provides an embodiment of an emergency command wireless broadband self-organizing network layer architecture diagram. The network layer is located between the upper application layer and the link layer, and mainly consists of three parts: link maintenance, routing management, and data processing. Link maintenance is mainly responsible for maintaining the link status, routing management is mainly responsible for maintaining the routing table, and data processing is mainly responsible for processing data transmission and reception. The network layer service interface can transmit different data flows, and the link layer service interface can interact with the network layer. Figure 2 The diagram also shows the network layer PDU (Protocol Data Unit) and the link layer PDU.

[0073] Please see Figure 3 , Figure 3 The following is a flowchart of the conformance test of the network layer protocol of an emergency command wireless broadband self-organizing network provided in the embodiments of this application. The specific process is as follows: After the test starts, the link maintenance function test, the routing management function test, and the data processing function process are performed. If all tests pass, the conformance test is deemed to have passed. If any test fails, the non-conformance item is rectified.

[0074] Please see Figure 4 , Figure 4 This is a physical topology diagram of the test environment constructed for conformance testing of the network layer protocol of emergency communication wireless broadband ad hoc networks, as provided in this application embodiment. The test environment includes hardware devices such as a computer, a first test device, a second test device, a third test device, the device under test, and a wireless channel simulator.

[0075] The computer establishes Ethernet connections with the first test device, the second test device, the third test device, and the device under test (DUT) via a network switch. The first test device, the second test device, the third test device, and the DUT are each connected to the RF interface of the wireless channel emulator via RF cables. The wireless channel emulator can flexibly establish logical topology relationships between the connected devices according to user settings, thereby meeting the needs of different test items.

[0076] The computer runs host computer software, which provides testers with an interface to perform conformance tests, enabling functions such as configuring test parameters, issuing test commands, and recording and displaying test results. The host computer software directly interacts with the corresponding test equipment or the device under test via a network switch to issue test commands and retrieve test results.

[0077] The first, second, and third test devices each run a standard emergency command wireless broadband self-organizing network protocol stack, which, together with the host computer software, performs tests on the device under test. The protocol stack, from bottom to top, includes the physical layer, data link layer, and network layer.

[0078] The first, second, and third test devices are identical. Their function is to connect directly to the host computer software via a network switch, receive test commands issued by the host computer software through the network port, parse the commands, convert them into a series of test messages, and send them to other test devices or the device under test through the radio frequency interface. When a feedback message is received, the feedback message is parsed to form a test result, and finally the test result is reported to the host computer test software through the network port.

[0079] The device under test runs an emergency command wireless broadband self-organizing network protocol stack developed by the manufacturer under test. The network layer protocol on this protocol stack is the object being tested.

[0080] As for Figure 1 In a further description of the corresponding embodiment, before setting the corresponding logical topology diagram for the item to be tested, the number of test devices connected to the computer can be counted, and then multiple logical topology diagrams can be generated based on the number of devices.

[0081] If the number of devices is 3 and the test devices include a first test device, a second test device, and a third test device, then the first logical topology diagram, the second logical topology diagram, the third logical topology diagram, and the fourth logical topology diagram can be set according to preset rules.

[0082] The above preset rules are:

[0083] In the first logical topology diagram, the first test device, the second test device, the third test device, and the device under test are sequentially connected in a chain-like topology.

[0084] In the second logical topology diagram, the first test device, the second test device, the device under test, and the third test device are connected in a chain-like topology in sequence;

[0085] In the third logical topology diagram, there is a topological connection between any two devices among the first test device, the second test device, the third test device and the device under test;

[0086] In the fourth logical topology diagram, the first test device, the second test device, the third test device, and the device under test are connected in a ring topology.

[0087] Please see Figure 5 , Figure 5 The first logical topology diagram provided in this application illustrates the connection relationship of radio frequency signals between four devices: a first test device, a second test device, a third test device, and a device under test (DUT). This connection relationship is formed by configuring a wireless channel simulator according to the needs of specific test cases. In the first logical topology diagram, the four devices form a chain-like topology connection, that is, the radio frequency signal emitted by the first test device can only be received by the second test device, the radio frequency signal emitted by the second test device can only be received by the first and third test devices, the device signal emitted by the third test device can only be received by the second test device and the DUT, and the signal emitted by the DUT can only be received by the third test device. Simultaneously, due to the multi-hop routing forwarding function inherent in the network layer protocol of the ad hoc network device, devices without direct connections can communicate with each other through the forwarding of intermediate devices. For example, the radio frequency signal emitted by the first test device can sequentially pass through the routing forwarding of the second and third test devices, ultimately reaching the DUT.

[0088] Please see Figure 6 , Figure 6 The second logical topology diagram provided in this embodiment of the application is also formed by configuring a wireless channel simulator. Figure 5 compared to, Figure 6The difference is that the third testing device and the device under test have been swapped.

[0089] Please see Figure 7 , Figure 7 The third logical topology diagram provided in this application embodiment is also formed by configuring a wireless channel simulator. In this logical topology diagram, the four devices form a topology that is directly connected to each other, that is, the radio frequency signal emitted by each device can be directly received by other devices.

[0090] Please see Figure 8 , Figure 8 The fourth logical topology diagram provided in this application embodiment is also formed by configuring a wireless channel simulator. In this logical topology diagram, the four devices form a ring-shaped topology. For example, the radio frequency signal emitted by the first test device can be received directly by the device under test, or it can be received by the device under test after being forwarded by the second and third test devices.

[0091] For the conformance testing of network layer protocols in wireless broadband ad hoc networks for emergency command communications, link maintenance function testing, routing management function testing, and data management function testing are conducted. The test sub-items and specific test operations for each test are as follows:

[0092] A. Link maintenance function test;

[0093] If the test item is a link maintenance function test, then the first logical topology diagram is set as the logical topology diagram corresponding to the link maintenance function test; wherein, the test sub-items of the link maintenance function test include a link layer detection link maintenance function sub-test and a network layer detection link maintenance function sub-test.

[0094] A1. The link layer detection and link maintenance function is explained as follows:

[0095] Test objective: To verify that the network layer protocol under test can update the routing status in the local routing table accordingly based on the link layer's detection of link establishment, disconnection, and restoration information between the local node and its neighboring nodes.

[0096] Test environment: Setting up the test environment as follows Figure 4 The physical topology diagram is shown.

[0097] The testing steps are as follows:

[0098] 1) Configure a wireless channel simulator to form a structure as follows: Figure 5 The chain-like logic topology shown;

[0099] 2) The device under test is powered on first. After 10 seconds of power-on, the local routing table of the device under test is queried.

[0100] 3) The third test device is powered on, and its network layer protocol is not working during the initial configuration of the third test device. After 6 seconds, the local routing table of the device under test is queried.

[0101] 4) Configure the wireless channel emulator, disconnect the connection between the third test device and the device under test, and query the local routing table of the device under test after 6 seconds;

[0102] 5) Configure the wireless channel emulator, restore the connection between the third test device and the device under test, and query the local routing table of the device under test after 6 seconds.

[0103] The expected results are as follows:

[0104] 1) After executing the above test step 2), the local routing table of the device under test should be found to be empty;

[0105] 2) After executing the above test step 3), a route entry with the destination node of the third test device should be found in the local routing table of the device under test;

[0106] 3) After executing the above test step 4), the local routing table of the device under test should be found to be empty;

[0107] 4) After executing the above test step 5), a route entry with the destination node of the third test device should be found in the local routing table of the device under test.

[0108] If the above expected result is achieved, the subtest result of the link layer detection link maintenance function subtest is "test passed"; if the above expected result is not achieved, the subtest result of the link layer detection link maintenance function subtest is "test failed".

[0109] A2. The description of the sub-test for network layer link maintenance function is as follows:

[0110] Test objective: To verify that the network layer protocol under test can detect the establishment, disconnection, and restoration of links between the local node and neighboring nodes based on the route advertisement broadcast messages, and thus update the routing status in the local routing table accordingly.

[0111] Test environment: Setting up the test environment as follows Figure 4 The physical topology diagram is shown.

[0112] The testing steps are as follows:

[0113] 1) Configure a wireless channel simulator to form a structure as follows: Figure 5 The chain-like logic topology shown;

[0114] 2) The device under test is powered on first. After 10 seconds of power-on, the local routing table of the device under test is queried.

[0115] 3) The third test device is powered on, the second test device is powered on 10 seconds later, and the local routing table of the device under test is queried 6 seconds later;

[0116] 4) Configure the wireless channel emulator, disconnect the connection between the second and third test devices, and query the local routing table of the device under test after 6 seconds;

[0117] 5) Configure the wireless channel emulator, restore the connection between the second and third test devices, and query the local routing table of the device under test after 6 seconds.

[0118] The expected results are as follows:

[0119] 1) After executing the above test step 2), the local routing table of the device under test should be found to be empty;

[0120] 2) After executing the above test step 3), two routing entries with the destination node being the third test device and the second test device should be found in the local routing table of the device under test;

[0121] 3) After executing the test step 4), the test device's local routing table should show only one routing entry with the destination node being the second test device.

[0122] 4) After executing the above test step 5), two routing entries should be found in the local routing table of the device under test, with the destination node being the third test device and the second test device.

[0123] If the above expected results are achieved, the subtest result of the network layer detection link maintenance function subtest is "test passed"; if the above expected results are not achieved, the subtest result of the network layer detection link maintenance function subtest is "test failed".

[0124] This embodiment can also determine whether the sub-test results of the link layer detection link maintenance function sub-test and the network layer detection link maintenance function sub-test are both passed.
