[0002] In order to realize the vulnerability test of access network in the laboratory's injected RF interconnection network test environment, it is crucial to find the network vulnerability boundary conditions. However, the traditional test scheme is based on controlling a test variable to increase or decrease in steps, while the other test boundary conditions are fixed. For the test scheme with multiple test variables, the traditional test scheme does not give the property description and relationship of these parameters, which easily leads to logical conflicts between parameters during execution. It is necessary to propose a method for describing the properties of electromagnetic events for network testing. Summary of the invention

[0003] The technical problem to be solved by the present invention is that, in the prior art, no description of the properties and mutual relationships of these parameters are given, which easily leads to logical conflicts between the parameters during execution.

[0031] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose, the present invention is described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0032] In the drawings, the thickness, size and shape of objects have been slightly exaggerated for ease of explanation. The drawings are only examples and are not drawn strictly to scale.

[0033] It should also be understood that the terms "comprises", "including", "having", "includes" and / or "comprising", when used in this specification, indicate the presence of the stated features, wholes, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, parts and / or combinations thereof. In addition, when expressions such as "at least one of..." appear after a list of listed features, they modify the entire listed features rather than modifying the individual elements in the list. In addition, when describing embodiments of the present application, "may" is used to mean "one or more embodiments of the present application". And, the term "exemplary" is intended to refer to an example or illustration.

[0034] As used herein, the terms "substantially," "approximately," and similar terms are used as terms of approximation, not degree, and are intended to account for the inherent variations in measurements or calculations that would be recognized by those of ordinary skill in the art.

[0035] Unless otherwise defined, all terms (including technical terms and scientific terms) used in this article have the same meaning as commonly understood by ordinary technicians in the field to which this application belongs. It should also be understood that terms (such as terms defined in commonly used dictionaries) should be interpreted as having the same meaning as their meaning in the context of the relevant technology, and will not be interpreted in an idealized or overly formal sense unless explicitly defined in this article.

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] The description of the method flow in the specification of the present invention and the steps of the flowchart in the drawings of the specification of the present invention do not have to be strictly executed according to the step numbers, and the method steps can be executed in a different order. Moreover, some steps can be omitted, multiple steps can be combined into one step, and / or one step can be decomposed into multiple steps.

[0038] For ease of understanding, the names of the elements involved in the search method in this method are explained:

[0039] Node: It is divided into network node and interference node. Network node is the node of the network under test. Interference node is part of the electromagnetic environment and emits interference signals.

[0040] Electromagnetic events: Electromagnetic environment parameters change in a fixed step, and the direction of the change is in the direction of network performance degradation. Electromagnetic environment parameters include: distance between network nodes, relative speed between network nodes, transmission power of interference nodes, number of comb spectra emitted by interference nodes, signal-to-interference ratio (SIR) of each comb spectrum emitted by interference nodes, bandwidth of each comb spectrum emitted by interference nodes, interference tolerance of interference nodes, bandwidth of broadband interference signals emitted by interference nodes, SIR of broadband interference signals emitted by interference nodes, etc. Electromagnetic events are step changes of the above parameters, which lead to deterioration of network performance. Changes that do not lead to degradation of network performance are not electromagnetic events.

[0041] Normal network performance: The terminal node connected to the multi-port channel simulator (such as Figure 1 As shown in the figure, the network can be networked and work normally, and the communication bit error rate of the terminal node is not greater than the qualified threshold.

[0042] Network performance degradation: The terminal nodes connected to the multi-port channel simulator (such as Figure 1 As shown in the figure, the network can be networked and work normally, but then the reception is interfered, which causes the communication bit error rate index of the terminal node to increase.

[0043] like Figure 1 As shown, Figure 1 The network is formed by interconnecting the controller, the multi-port channel module, the interference source, and k terminal nodes. Specifically, the terminal node can interact with the multi-port channel module through a radio frequency cable, the controller can interact with the multi-port channel module and the interference source through a network cable, and the interference source can send an interference signal to the multi-port channel module through a radio frequency cable.

[0044] The first embodiment of the present invention is a method for determining the correctness of the comb spectrum output by an interference source, such as Figure 2 As shown, the specific steps include:

[0045] Step 1, based on preset property description parameters, the electromagnetic events involved in the network test are described in terms of properties, wherein the electromagnetic events include events that cause network performance degradation in the network test;

[0046] Step 2, determine whether there is a logic conflict between different electromagnetic events.

[0047] The method provided in this embodiment will be described in detail step by step below.

[0048] Step 1, based on preset property description parameters, the electromagnetic events involved in the network test are described in terms of properties, wherein the electromagnetic events include events that cause network performance degradation in the network test;

[0049] Specifically, the properties of electromagnetic events involved in the network test can be described. For example, there are N electromagnetic events, where the properties of the nth (n=1...N) electromagnetic event are described as shown in Table 1 below:

[0050] Table 1

[0051]

[0052]

[0053] Step 2, determine whether there is a logic conflict between different electromagnetic events.

[0054] In this embodiment, step 2 may further include:

[0055] Step 201: Determine whether the parameters of the nth event and the mth event (n≠m) are of the same type. If they are different, determine that there is no logical conflict between the nth event and the mth event; otherwise, proceed to step 202;

[0056] Step 202: Determine whether the parameter distribution topology of the nth event and the mth event (n≠m) is the same. If they are different, determine that there is no logical conflict between the nth event and the mth event; otherwise, proceed to step 203;

[0057] Step 203: Determine whether the electromagnetic device labels of the nth event and the mth event (n=1...N, m=1...N, and n≠m) for executing the parameter value are the same; if they are different, determine that there is no logical conflict between the nth event and the mth event; otherwise, determine that there is a logical conflict between the nth event and the mth event.

[0058] It can be understood that this embodiment is applied to a description application scenario where there are at least two electromagnetic events to determine whether there is a description conflict between any two of them.

[0059] In this embodiment, the network performance degradation caused by the electromagnetic event is determined by the bit error rate and packet loss rate of at least one node in the network test. That is to say, the bit error rate and packet loss rate of at least one node in the network test can be used to determine whether an electromagnetic event exists in the current network. By way of example, the monitoring of electromagnetic events can be implemented by using threshold monitoring and other related technologies for the bit error rate and packet loss rate.

[0060] It should be noted that the property description parameters can be adjusted and reasonably configured within an appropriate range according to the application scenario or the change of its own needs, and the subsequent judgment conditions can also be adjusted accordingly according to the actual situation. It should be noted that the above is only an exemplary description and does not limit the scope of protection of the present invention.

First, an electromagnetic event property description system is constructed to describe parameter properties from the perspectives of distribution topology, value range, step strategy, etc., and then event logic conflict judgment is performed to determine whether the event logic conflicts from the type of parameter, parameter distribution topology, and the number of the electromagnetic device that executes the parameter value. This method effectively regulates the property range of test parameters in semi-physical injection networking tests and avoids logical conflicts when multiple parameters change.

If they are different, determine that there is no logical conflict between the first event and the second event; otherwise, determine that there is a logical conflict between the first event and the second event.

[0070] In some embodiments, the degradation of network performance caused by the electromagnetic event is determined by a bit error rate and a packet loss rate of at least one node in a network test.

[0073] Step 2: determine whether there is a logical conflict between different electromagnetic events.

[0074] A fourth embodiment of the present invention is a computer storage medium, wherein a computer program is stored on the computer-readable storage medium, and when the computer program is executed by a processor, the steps of the method for describing properties of electromagnetic events based on network testing as described in the first embodiment are implemented.

[0075] The fifth embodiment of the present invention is based on the above embodiment and combined with the attached Figure 5 An application example of the present invention is introduced.

[0076] Reference Figure 5 , Figure 5 The overall process of the electromagnetic event property description method for network testing in this embodiment is described. First, an electromagnetic event property description system is constructed to describe parameter properties from the perspectives of distribution topology, value range, step strategy, etc., and then event logic conflict judgment is performed to determine whether the event logic conflicts from the perspectives of parameter type, parameter distribution topology, and the electromagnetic device number that executes the parameter value.

[0077] To simplify the analysis, the channel simulator used in this example system has 8 ports, the ports are in duplex mode, the number of terminal nodes accessing the channel simulation is 3, and there is one interference source. The specific operation is:

[0078] Step 1: Initialization, describe the properties of the electromagnetic events involved in the network test. Suppose there are two electromagnetic events, where the properties of the first electromagnetic event are described in Table 2 below, and the properties of the second electromagnetic event are described in Table 3 below.

[0083]

[0084] Step 2: Event logic conflict judgment:

[0085] Step (2-1): If it is determined that the parameters of the first event and the second event are of different types, then proceed to step 3;

[0086] Step 3: Determine that there is no logical conflict between the first event and the second event, and the description of the nature of the electromagnetic event is completed.

[0087] Through the description of the specific implementation methods, a deeper and more specific understanding of the technical means and effects adopted by the present invention to achieve the predetermined purpose should be obtained.
