[0046] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] See also Figure 1 , is a flow chart of an interference testing method provided by an embodiment of the present invention. An interference testing method is provided by an embodiment of the present invention, which is applied to a communication simulation platform, and the communication simulation platform includes several functional nodes.

[0048] It should be noted that in the existing communication simulation platform technology, the functional nodes only support base station functions and terminal functions. By configuring the nodes with base station and terminal functions, a simulated communication architecture is constructed. When interference testing is required, additional professional RF signal generating equipment is equipped to provide interference testing capabilities.

[0049] In order to solve the problem that the existing communication simulation platform does not have native interference testing capabilities, and taking into account the high price and excessive functions of professional RF signal generating equipment, as well as the narrow scope of application of some interference testing technologies, an embodiment of the present invention provides a new interference testing method, aiming to fill the gap between these three.

[0050] The interference test method comprises steps S11 and S12:

[0051] S11. Acquire configuration information of the function node by the user; wherein the configuration information includes a function type and a function configuration parameter corresponding to the function type; the function type is an interference function type or a communication function type;

[0052] S12. Configure the function node according to the configuration information so that the function node performs a corresponding function.

[0053] Specifically, see Figure 2 and Figure 3 , Figure 2 is a first schematic diagram of a test architecture of a communication simulation platform in an embodiment of the present invention, Figure 3 This is the second schematic diagram of the test architecture of the communication simulation platform in the embodiment of the present invention. In the embodiment of the present invention, each functional node of the communication simulation platform retains the original communication function type, such as base station function and terminal function, and a new interference function type is added to each functional node. The functional node configured as the interference function type is responsible for reading the configuration, generating interference signals, performing time control and sending interference signals through the radio frequency module, thereby realizing the function of the interference signal generator.

[0054] In addition, each functional node can be flexibly switched between different functional types, that is, each functional node can be configured as a communication node, such as a base station node, a terminal node, etc., or it can be configured as an interference node, so that in the communication simulation platform, the roles of the simulated base station, the simulated terminal and the interference signal generator can be flexibly interchanged, providing a more flexible test architecture.

[0055] During the application process, the simulation platform receives the user's configuration information for each functional node, and configures the functional node according to the interference function type or communication function type specified in the configuration information, and the corresponding specific function configuration parameters, so that each functional node performs the corresponding interference function or communication function according to the configuration situation. By configuring the base station, terminal and interference function of each functional node, data communication test and interference test are performed on the communication simulation platform.

[0056] It is understandable that the number of functional nodes in the communication simulation platform can be set according to the needs, for example, a multi-terminal scenario or a multi-base station scenario can be tested, providing more flexibility for the test architecture. Figure 4 , is a third schematic diagram of the test architecture of the communication simulation platform in an embodiment of the present invention. In a multi-terminal scenario, two or more functional nodes are set as terminal nodes, and one functional node is configured as a base station node, and at least one functional node can be configured as an interference node according to requirements; see Figure 5 , is the fourth schematic diagram of the test architecture of the communication simulation platform in an embodiment of the present invention. In a multi-base station scenario, two or more functional nodes are set as base station nodes, and one functional node is configured as a terminal node, and at least one functional node can be configured as an interference node according to requirements.

[0057] By adopting the technical means of the embodiments of the present invention, the interference signal generation function is realized on the functional nodes of the communication simulation platform, so that the functional nodes can generate interference signals, so that the simulation platform has native and universal interference testing capabilities, and there is no need to be equipped with external testing equipment, which effectively simplifies the simulation platform structure and reduces the testing cost. In addition, the present invention can support multi-scenario and multi-type test configurations, effectively improving the test flexibility and versatility.

[0058] As a preferred implementation, the embodiment of the present invention is further implemented on the basis of the above embodiment, step S12, that is, configuring the functional node according to the configuration information so that the functional node completes the corresponding function, includes steps S121 to S122:

[0059] S121. When the function type is a communication function type, configure the function node according to the function configuration parameters corresponding to the communication function type so that the function node performs a data communication function; wherein the function configuration parameters corresponding to the communication function type include a communication node type and a communication configuration parameter.

[0060] S122. When the function type is an interference function type, the function node is configured according to the function configuration parameters corresponding to the interference function type so that the function node performs the function of generating an interference signal; wherein the function configuration parameters corresponding to the interference function type include an interference type and an interference configuration parameter.

[0061] In the embodiments of the present invention, see Figure 6 , is a flowchart of a preferred interference test method in an embodiment of the present invention. In an implementation scenario, when the function node is configured as a communication function node of a communication function type, the specific communication node type of the function node is further determined, and the communication node type includes a base station function node and a terminal function node, and is configured according to corresponding communication configuration parameters. Figure 6 As shown, the data transmission and reception process of the communication function nodes in a typical 5G communication simulation platform is completed by a communication main thread. The thread implementation includes synchronous detection, asynchronous data reading (from the RF device), baseband signal processing, data transmission preparation, strict time synchronization sending of data transmission requests, waiting for data transmission results, and entering the next data transmission and reception process.

[0062] It should be noted that, for communication node types such as terminal function nodes and base station function nodes, their corresponding communication configuration parameters can refer to the relevant settings of the prior art and are not specifically limited here.

[0063] In another implementation scenario, when the functional node is configured as an interference functional node of an interference functional type, the specific interference type of the functional node is further determined. This solution defines five different interference types, including continuous interference, reactive interference, periodic interference, random interference, and specific time-frequency domain interference. The specific description is as follows:

[0064] Continuous interference: sending interference signals continuously;

[0065] Reactive interference: The interference signal is sent only when normal signal transmission and reception are detected;

[0066] Periodic interference: Repeatedly send interference signals at preset time intervals;

[0067] Random interference: randomly send interference signals;

[0068] Specific time-frequency domain interference: Accurately implement interference in specific 5G time-frequency domains.

[0069] The embodiment of the present invention designs corresponding interference configuration parameters and algorithms for each interference type. By configuring different types of interference and adjusting corresponding parameters, interference testing can be effectively performed in multiple scenarios. The embodiment of the present invention adds an interference main thread to specifically complete interference tasks. Figure 6 The specific description is as follows:

[0070] When the user chooses to configure it as an interference node, the interference thread is started; the interference type is selected according to the user configuration; the configuration of the corresponding interference type is read in, including the transmission duration, period, time-frequency domain information, etc.; an interference signal is generated; the RF module interface is called to initiate a signal transmission request; wait for the interference signal to be sent; perform time control according to the configuration and wait for the next transmission time; enter the next interference transmission process.

[0071] Preferably, the interference configuration parameters corresponding to different interference types are optimized as follows:

[0072] The interference configuration parameters corresponding to the continuous interference include test duration;

[0073] The interference configuration parameters corresponding to the reactive interference include test duration and interference signal transmission duration;

[0074] The interference configuration parameters corresponding to the periodic interference include test duration, interference period and interference signal transmission duration;

[0075] The interference configuration parameters corresponding to the random interference include test duration, interference signal transmission duration, and interference signal stop duration; wherein the interference signal transmission duration and the interference signal stop duration are randomly generated;

[0076] The interference configuration parameters corresponding to the specific time-frequency domain interference include a test duration, a target resource block in the time-frequency domain, and a target time slot.

[0077] Preferably, in step S122, configuring the function node according to the function configuration parameter corresponding to the interference function type so that the function node performs the function of generating an interference signal includes:

[0078] When the interference type is continuous interference, configuring the functional node to continuously generate an interference signal within the test duration according to the interference configuration parameter;

[0079] When the interference type is reactive interference, configuring the functional node according to the interference configuration parameters within the test duration to continuously generate an interference signal within the interference signal transmission duration if a synchronization signal is detected;

[0080] When the interference type is periodic interference, configuring the functional node to continuously generate an interference signal within the interference signal transmission duration of each interference period within the test duration according to the interference configuration parameter;

[0081] When the interference type is random interference, configuring the functional node to continuously generate interference within the test duration and the interference signal transmission duration according to the interference configuration parameters, and to stop generating the interference signal within the interference signal stop duration;

[0082] When the interference type is specific time-frequency domain interference, the functional node is configured to generate an interference signal on a target time slot of a target resource block in the time-frequency domain within the test duration according to the interference configuration parameters.

[0083] Specifically, for each interference type, the designed interference configuration parameters and algorithms are as follows:

[0084] Continuous interference generates continuous and non-stop interference signals. It has only one configuration parameter: T (test duration). The user configures the specific value of this parameter, and the interference thread reads and continuously emits interference for T seconds, and then the test ends.

[0085] Reactive interference is when a normal signal is detected before an interference signal is generated. It has two configuration parameters, T (test duration) and tn (transmission duration). The interference thread first detects the wireless air interface signal, and when a signal is found, it generates interference for tn seconds, then re-enters the listening phase, and repeats this process. The test ends when the test duration reaches T seconds.

[0086] Periodic interference generates an interference signal with a fixed period. Define a tuple (tp, tx), where tp refers to an interference period and tx refers to the time when the interference signal is emitted in the interference period. The configuration parameters of periodic interference are T (test duration) and the tuple (tp, tx). In each period of tp seconds, the interference thread first emits an interference signal for tx seconds, then pauses for (tp-tx) seconds, and then enters the next period, and repeats in sequence. The test ends when the test duration reaches T seconds.

[0087] The configuration parameters for random interference are similar to those for periodic interference, including T (test duration) and a binary (tpr, txr). The main difference is that tpr and txr are randomly generated values ​​before each interference (where tpr>txr). During each interference, the interference thread first emits an interference signal for txr seconds, then pauses for (tpr-txr) seconds, and then enters the next interference, and repeats this process. The test ends when the test duration reaches T seconds.

[0088] Specific time-frequency domain interference means that the interference occurs in the time-frequency domain specified by the user. In the 5G NR frame structure, a radio frame lasts for 10 milliseconds and consists of 10 radio subframes. Each subframe consists of a different number of time slots (slots) depending on the subcarrier spacing. In a typical 30kHz subcarrier spacing configuration, a subframe consists of 2 slots, and a radio frame contains 20 slots. The parameter ts is defined to represent the slot number. For example, the range of the configured slot can be from 0 to 19. The frequency domain structure of 5G NR consists of resource blocks RB (Resource Block). A typical 100M bandwidth 30kHz subcarrier configuration has 273 RBs. The parameter tf is defined to represent the target resource block RB where the interference signal needs to occur in the frequency domain.

[0089] The configuration parameters for specific time-frequency domain interference are T (test duration) and a tuple (ts, tf), where the tuple represents the time slot and frequency resource block where the interference occurs. When the interference thread reaches the configured time slot, it transmits the interference signal on the specified frequency resource block to generate accurate, user-specified time-frequency domain interference. The test ends when the test duration reaches T seconds.

[0090] See also Figure 7 , is a flowchart of another preferred interference test method in an embodiment of the present invention, in which the simulation platform enters different interference type branch processing flows according to the configured interference type and parameters. The specific description is as follows:

[0091] For continuous interference: generate an interference signal; initiate a request to prepare to send the interference signal; block the process and wait for the interference signal to be sent; enter the next interference sending process, and repeat this process.

[0092] For reactive interference: listen for synchronization signals; when a synchronization signal is detected, enter the following process; generate an interference signal; initiate a request to prepare to send an interference signal; the process is blocked and waits for the interference signal to be sent; enter the next interference sending process, and repeat this process.

[0093] For periodic interference: read in the periodic interference configuration; perform time monitoring, and when the sending cycle is reached, send interference; generate an interference signal; initiate a request to prepare to send the interference signal; the process is blocked, waiting for the end of the interference signal sending; enter the next interference sending process, and repeat this process.

[0094] For random interference: generate random configuration; perform time monitoring, and when the randomly generated sending cycle is reached, send interference; generate interference signal; initiate a request to prepare to send the interference signal; process blocking, waiting for the end of the interference signal sending; enter the next interference sending process, and repeat this process.

[0095] For specific time-frequency domain interference: read in the detailed interference configuration information; perform time monitoring, and when the designated sending time slot is reached, perform interference transmission; generate a designated frequency domain interference signal; initiate a request to prepare to send the interference signal; the process is blocked, waiting for the end of the interference signal transmission; enter the next interference transmission process, and repeat this process.

[0096] By adopting the technical means of the embodiments of the present invention, the interference signal generation function is realized on the functional nodes of the communication simulation platform, and various interference types and their interference configuration parameters are specifically optimized, so that the simulation platform has interference testing capabilities, and the simulation nodes can flexibly switch between communication functions and interference functions. In lightweight interference testing scenarios, no additional professional testing equipment is required, and multi-scenario and multi-type test configurations can be supported. Multiple interference types and their interference configuration parameters and algorithms are designed for 5G interference scenarios and are lightweight, which effectively improves the test flexibility and versatility. The native interference testing capability also makes the process of interference testing in a 5G simulation environment more standardized and cost-effective.
