[0002] In existing technologies, when performing network detection, terminals typically detect basic information about the serving cell, downlink reference signal received power (RSRP), and / or downlink signal to interference plus noise ratio (SINR), thereby determining the network coverage of the serving cell. However, currently, terminals cannot determine whether uplink interference or co-channel interference exists in the serving cell. Summary of the Invention

[0003] The purpose of this application is to provide an interference detection method, device, terminal, and readable storage medium to solve the problem that current terminals cannot determine whether uplink interference and co-channel interference exist in the serving cell.

[0025] 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.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] The interference detection method, apparatus, terminal, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0028] Please see Figure 1 , Figure 1 This is a flowchart of an interference detection method provided in an embodiment of this application. The method is applied to a terminal, such as... Figure 1 As shown, the method includes the following steps:

[0029] Step 11: Execute simulated business packet sending to obtain the packet sending success rate.

[0030] In this embodiment, a simulated service model can be set in the terminal to simulate service packet sending. The simulated service model can include the data packet size P_size and the number of data packets sent P_number to calculate the packet sending success rate P_success.

[0031] Step 12: Obtain the downlink RSRP and downlink SINR of the serving cell.

[0032] In some embodiments, after obtaining the packet success rate P_success, P_success can be compared with the packet success rate threshold P_success_threshold. If P_success ≤ P_success_threshold, indicating significant interference in the serving cell, the downlink signal-to-interference-plus-noise ratio (SINR) and downlink reference signal-receiving power (RSRP) of the serving cell can be further obtained to determine whether to trigger uplink interference detection or co-channel interference detection. If P_success < P_success_threshold, it indicates that the interference in the serving cell is relatively small, and neither uplink interference detection nor co-channel interference detection needs to be triggered.

[0033] Step 13: Based on the packet transmission success rate, downlink RSRP, and downlink SINR, determine whether to trigger uplink interference detection or co-channel interference detection, and obtain the determination result.

[0034] The determination result obtained in step 13 can be triggering uplink interference detection, triggering co-channel interference detection, or not triggering uplink interference detection and co-channel interference detection, etc.

[0035] Step 14: Perform interference detection based on the judgment results.

[0036] The interference detection method in this application embodiment can perform simulated service packet transmission, obtain the packet transmission success rate, and acquire the downlink RSRP and downlink SINR of the serving cell. Based on the packet transmission success rate, downlink RSRP, and downlink SINR, it determines whether to trigger uplink interference detection or co-channel interference detection, obtains the determination result, and performs interference detection based on the determination result. Therefore, the terminal system can systematically determine whether uplink interference and co-channel interference exist in the serving cell, thereby accurately determining the interference situation of the serving cell.

[0037] In this embodiment, it can be determined whether to trigger uplink interference detection or co-channel interference detection based on pre-set interference detection thresholds for downlink RSRP and downlink SINR. The determination process in step 13 above may include:

[0038] Compare the packet success rate with the packet success rate threshold; the packet success rate threshold can be set based on actual needs and is a simulated packet success rate threshold used to determine whether there is a problem at the detection location. That is, if the packet success rate is less than or equal to the packet success rate threshold, it indicates that there is a problem at the detection location; otherwise, if the packet success rate is greater than the packet success rate threshold, it indicates that there is no problem at the detection location.

[0039] When the packet success rate is less than or equal to the packet success rate threshold, the downlink RSRP is compared with the first interference detection threshold, and the downlink SINR is compared with the second interference detection threshold; wherein, the first interference detection threshold is a preset interference detection threshold for downlink RSRP, and the second interference detection threshold is a preset interference detection threshold for downlink SINR.

[0040] If the downlink RSRP is greater than or equal to the first interference detection threshold and the downlink SINR is greater than or equal to the second interference detection threshold, that is, the signal strength and signal-to-noise ratio at the measurement location are good, but the service success rate is low, then uplink interference detection is triggered; or if the downlink RSRP is greater than or equal to the first interference detection threshold and the downlink SINR is less than the second interference detection threshold, that is, the signal strength at the measurement location is good, but the signal-to-noise ratio is very low and the downlink interference is large, then co-channel interference detection is triggered.

[0041] In this way, by using the interference detection thresholds of downlink RSRP and downlink SINR, it is possible to accurately determine whether uplink interference detection or co-channel interference detection is triggered.

[0042] Understandably, if the downlink RSRP is less than the first interference detection threshold and the downlink SINR is less than the second interference detection threshold, it indicates that the signal coverage of the serving cell is poor, and the signal coverage of the serving cell needs to be adjusted. Uplink interference and co-channel interference generally coexist. The above determination process is used to determine whether uplink interference or co-channel interference is dominant, and then further trigger uplink interference detection or co-channel interference detection.

[0043] Optionally, when the determination result is to trigger uplink interference detection, the above-mentioned process of interference detection based on the determination result may include: first, obtaining a first rise value of the terminal's transmit power; wherein, the first rise value is equal to the difference between the terminal's transmit power when it first successfully transmits data and the initial transmit power; then, comparing the first rise value with a preset interference detection offset value, which can be set based on actual needs to avoid misjudgment caused by cell uplink interference jitter; finally, if the first rise value is greater than or equal to the interference detection offset value, determining that the serving cell has uplink interference; or, if the first rise value is less than the interference detection offset value, determining that the serving cell does not have uplink interference.

[0044] In some embodiments, the initial transmit power can be set based on the noise floor and obtained by the terminal from the base station. In this case, the first boost value mentioned above can also be understood as the boost value of the noise floor.

[0045] Optionally, when the terminal obtains the first boost value of its transmission power, it can gradually increase the terminal's transmission power based on the boost step size S after the terminal fails to transmit data at the initial transmission power, and retransmit the data based on the boosted transmission power; then, when the terminal successfully transmits data for the first time with the transmission power boosted n times, it determines that the first boost value is equal to the product of the boost step size S and n; where n is an integer greater than 0.

[0046] In some embodiments, the lifting step size S can be preset based on actual conditions, or it can be obtained by the terminal from the base station.

[0047] In some embodiments, the terminal can receive the maximum number of retransmissions N from the base station, and if no data is successfully transmitted within the maximum number of retransmissions N, determine that the first rise value is greater than the product of the rise step size S and N. In this case, other methods can be used to determine whether uplink interference exists.

[0048] Optionally, when the determination result is to trigger uplink interference detection, the presence of uplink interference can be determined based on the uplink noise floor value of the serving cell at the current time. The above-mentioned interference detection process based on the determination result may include: first, obtaining the uplink noise floor value of the serving cell at the current time; then, determining whether the serving cell has uplink interference based on the uplink noise floor value and a first noise floor value; wherein, the first noise floor value is the uplink noise floor value of the serving cell under interference-free conditions.

[0049] Furthermore, the terminal can determine that uplink interference exists in the serving cell if the uplink noise floor value is greater than or equal to the sum of the first noise floor value and a preset noise floor offset value; or, if the uplink noise floor value is less than or equal to the difference between the first noise floor value and the preset noise floor offset value, it can determine that there is no uplink interference in the serving cell. The preset noise floor offset value can be set based on actual needs.

[0050] Optionally, to obtain the uplink noise floor value of the serving cell at the current moment, any of the following methods can be used:

[0051] 1) Manually obtain the uplink noise floor value of the serving cell at the current moment. For example, based on the information of the serving cell, you can manually request the uplink noise floor value of the serving cell at the current moment from the network management platform and input it into the terminal.

[0052] 2) The terminal automatically obtains the uplink noise floor value of the serving cell at the current moment.

[0053] Optionally, the terminal can send a request message to the network management platform (or network management center); wherein the request message is used to request the uplink noise floor value of the serving cell at the current time; and then, the terminal receives the uplink noise floor value of the serving cell at the current time from the network management platform.

[0054] In some embodiments, the above request message includes at least serving cell information and the current time timestamp, and the network management platform determines the uplink noise floor value of the serving cell at the current time based on this information.

[0055] In some embodiments, when a terminal sends a request message, it can first send the request message to a designated server, such as a server dedicated to providing forwarding requests to the terminal. Then, the designated server forwards the request message to the network management center, so that the network management platform can send the uplink noise floor value of the serving cell at the current moment to the terminal.

[0056] It should be noted that, in this embodiment, the terminal can also send relevant detection information to the network management platform for uplink interference analysis. For example, the terminal can report serving cell information, timestamps, and downlink SINR_serving and RSRP_serving measurements to the network management platform. The network management platform can then query the uplink noise floor value of the serving cell at the current time based on the information, and analyze the uplink interference of the serving cell by combining downlink SINR_serving, RSRP_serving, and power control parameters, and feed the analysis results back to the terminal.

[0057] Optionally, when uplink interference is determined to exist in the serving cell, the terminal can analyze the power control parameter configuration of the serving cell and provide configuration suggestions. The specific process may include: first, calculating a second rise value of the serving cell's uplink noise floor; where this second rise value is equal to the difference between the serving cell's uplink noise floor at the current moment and its uplink noise floor under interference-free conditions; then, determining the target received power of the communication channel at the current moment based on the second rise value and the target received power of the communication channel under interference-free conditions; finally, determining the power control parameter configuration suggestions based on the target received power of the communication channel at the current moment. In this way, with the help of configuration suggestions, the efficiency of locating cell interference problems can be effectively improved, thereby optimizing the configuration of the serving cell and promoting network optimization.

[0058] In some embodiments, the aforementioned communication channel may be a Physical Random Access Channel (PRACH), a Physical Uplink Shared Channel (PUSCH), or the like. Further, the PRACH may be an NPRACH (narrowband PRACH), and the PUSCH may be an NPUSCH (narrowband PUSCH), or the like.

[0059] For example, if the uplink noise floor rise of the serving cell is D, then a reasonable configuration considering uplink interference for the target received power of NPRACH, Msg3, and NPUSCH can be:

[0060] TargetPower_NPRACH_Reasonable=D+Power_NPRACH_nonoise;

[0061] TargetPower_PUSCH_Msg3_Reasonable=D+Power_PUSCH_Msg3_nonoise;

[0062] TargetPower_NPUSCH_Reasonable=D+Power_NPUSCH_nonoise;

[0063] Among them, Power_NPRACH_nonoise, Power_PUSCH_Msg3_nonoise, and Power_NPUSCH_nonoise represent the target received power of NPRACH, the target received power of Msg3, and the target received power of NPUSCH configured by the base station in the absence of uplink interference. Subsequently, the obtained power control parameter configuration suggestions TargetPower_NPRACH_Reasonable, TargetPower_PUSCH_Msg3_Reasonable, and TargetPower_NPUSCH_Reasonable can be provided to the user or network management platform.

[0064] In some embodiments, the terminal can specify the receive power of the NPRACH and NPUSCH configured in the current serving cell in the SIB2 message. If the target receive power of the determined NPRACH and NPUSCH at the current time differs significantly from the currently configured receive power, the terminal can provide a suggestion to configure the NPRACH and NPUSCH based on the target receive power. Otherwise, if the two are close, reconfiguration can be discouraged to save signaling overhead.

[0065] Optionally, when the determination result is to trigger co-channel interference detection, the above-mentioned interference detection process based on the determination result may include: first, measuring the RSRP and / or reference signal received quality of the co-channel frequency points in neighboring cells. The process involves several steps: First, comparing the RSRP of the serving cell with the RSRP of a neighboring cell at the same frequency, and / or comparing the RSRQ of the serving cell with the RSRQ of a neighboring cell at the same frequency. Finally, if the first absolute value is less than or equal to a preset signal strength offset value, and / or the second absolute value is less than or equal to a preset signal quality offset value (i.e., the neighboring cell's signal at the same frequency is similar to or better than the serving cell's signal), then it is determined that the serving cell experiences co-channel interference. Alternatively, if the first absolute value is greater than the signal strength offset value, and the second absolute value is greater than the signal quality offset value (i.e., the neighboring cell's signal at the same frequency is worse than the serving cell's signal), then it is determined that the serving cell does not experience co-channel interference. Here, the first absolute value is the absolute value of the difference between the serving cell's RSRP and the neighboring cell's RSRP; the second absolute value is the absolute value of the difference between the serving cell's RSRQ and the neighboring cell's RSRQ. This method allows for the determination of whether co-channel interference exists.

[0066] Understandably, the above signal strength bias value and signal quality bias value can be set based on actual needs, and there are no restrictions on this.

[0067] Optionally, when it is determined that co-channel interference exists in the serving cell, the terminal may report at least one of the following: the location information of the serving cell, the neighboring cell number where co-channel interference exists, and the intensity of the co-channel interference. For example, the terminal may report to the network management platform or the base station. By using the reported information, the efficiency of locating cell interference problems can be effectively improved, thereby facilitating the determination of the location of severe co-channel interference and enabling the deployment of different frequency points in the vicinity of the corresponding area, thus promoting network optimization.

[0068] The following is combined with Figures 2 to 5 This application will be described in detail.

[0069] Please see Figure 2 , Figure 2 This is a schematic diagram of the interference detection device provided in a specific example of this application, which is applied to a terminal. For example... Figure 2As shown, the interference detection device 20 includes: a detection triggering device 21, a parameter reading device 22, an uplink interference detection device 23, a co-channel interference detection device 24, and a result output device 25. The detection triggering device 21 is mainly used to simulate service packet transmission, analyze packet success rate, downlink RSRP, and downlink SINR, and trigger either the uplink interference detection device 23 or the co-channel interference detection device 24 based on the analysis results. The parameter reading device 22 is mainly responsible for reading the network parameters required for uplink interference detection and co-channel interference detection, supporting the detection and analysis process, and is used throughout the entire interference detection process. The uplink interference detection device 23 may include an uplink interference detector 231 and a network parameter analyzer 232, used to detect uplink interference, analyze power control parameter configuration, and send the detection results to the result output device 25. The co-channel interference detection device 24 may include a co-channel interference detector 241, used to detect and analyze cell co-channel interference, and send the detection results to the result output device 25. The result output device 25 is mainly used to receive the detection results from the uplink interference detection device 23 and the co-channel interference detection device 24, and output the service cell interference situation and suggested solutions to the user or network management platform.

[0070] Please see Figure 3 , Figure 3 This is a flowchart illustrating the interference detection and configuration analysis process provided in a specific example of this application. For example... Figure 3 As shown, the corresponding process includes:

[0071] Step 301: Start interference detection.

[0072] Step 302: Execute simulated business packet sending and obtain the packet sending success rate P_success.

[0073] Step 303: Determine whether the packet success rate P_success is lower than the packet success rate threshold P_success_threshold. If P_success is higher than P_success_threshold, there is no interference problem; if P_success is lower than or equal to P_success_threshold, proceed to step 34.

[0074] Step 304: Obtain the downlink RSRP_serving and downlink SINR_serving of the serving cell.

[0075] Step 305: Based on downlink SINR_serving and downlink RSRP_serving, determine whether to trigger uplink interference detection or co-channel interference detection.

[0076] Optionally, if the downlink SINR_serving of the serving cell is greater than or equal to SINR_up_det, and SINR_serving is greater than or equal to RSRP_up_det, indicating good signal strength and signal-to-noise ratio but low service success rate, uplink interference detection is triggered; RSRP_up_det and SINR_up_det are the uplink interference detection thresholds for RSRP and SINR, respectively. Alternatively, if the downlink SINR_serving of the serving cell is less than or equal to SINR_down_det, and RSRP_serving is greater than or equal to RSRP_down_det, indicating a low signal-to-noise ratio and significant downlink interference in a location with good cell signal, co-channel interference detection is triggered; RSRP_down_det and SINR_down_det are the co-channel interference detection thresholds for RSRP and SINR, respectively.

[0077] Understandably, steps 301 to 305 described above can be performed in the detection triggering device 21.

[0078] If uplink interference detection is triggered, the uplink interference detection device 23 is activated, the uplink interference detection process is started, and steps 306 to 311 are executed. If co-channel interference detection is triggered, the co-channel interference detection device 24 is activated, the co-channel interference detection process is started, and steps 312 to 315 are executed.

[0079] Step 306: Obtain relevant parameters of the serving cell, such as the serving cell's frequency, physical cell identifier (PCI), E-UTRAN cell identifier (ECI), and tracking area code (TAC).

[0080] Step 307: Obtain the uplink noise floor N_up of the serving cell based on the relevant parameters of the serving cell.

[0081] It should be noted that the method for obtaining the uplink noise floor N_up of the serving cell in step 37 can be found in the above embodiments, and will not be repeated here.

[0082] Step 308: Determine whether uplink interference exists based on the uplink noise floor N_up of the serving cell. If no uplink interference is found, the detection ends and the detection result is output; otherwise, proceed to step 309.

[0083] Optionally, if N_up > N_none + N_offset, then the serving cell has uplink interference. Alternatively, if N_up ≤ N_none - N_offset, then the serving cell does not have uplink interference. Here, N_none is the uplink noise floor of the serving cell under interference-free conditions, and N_offset is a preset noise floor offset value.

[0084] Understandably, steps 306 to 308 described above can be performed in the uplink interference detector 231.

[0085] Step 309: Obtain the power control parameters of the serving cell.

[0086] Step 310: Analyze the rationality of the power control parameter settings.

[0087] Step 311: Determine the recommended power control parameter configuration.

[0088] It should be noted that the analysis and configuration recommendations in steps 309 to 311 can be found in the above embodiments and will not be repeated here. Steps 309 to 311 can be executed in the network parameter analyzer 232.

[0089] Step 312: Obtain the reference signal parameters of the same frequency point cell.

[0090] Step 313: Obtain the RSRP_n and RSRQ_n of the neighboring cells with the same frequency (n is the number of the different neighboring cells).

[0091] Step 314: Compare the quality and strength of the co-channel signal from the neighboring cell with the signal from the serving cell to determine whether co-channel interference exists. If no co-channel interference is found, the detection ends and the detection result is output; otherwise, if co-channel interference is found, proceed to step 315.

[0092] For example, if |RSRP_serving-RSRP_n|≤RSRP_delta, or |RSRQ_serving-RSRQ_n|≤RSRQ_delta, it indicates that the co-channel signal of the neighboring cell is similar to or better than the serving cell's signal, indicating co-channel interference. Otherwise, there is no co-channel interference. RSRP_delta and RSRQ_delta are bias values ​​used to compare the signal quality of the neighboring cell and the serving cell.

[0093] Step 315: Obtain the geographical location of the serving cell, the cell number of the cell with co-channel interference, and the interference intensity, and feed the information back to the user or network management platform to facilitate the determination of the location of severe co-channel interference.

[0094] Understandably, steps 312 to 315 can be performed in the co-channel interference detector 241 of the co-channel interference detection device 24.

[0095] Furthermore, after receiving the detection results from the uplink interference detection device 23 and the co-channel interference detection device 24, the result output device 25 can output uplink interference detection results, reasonable parameter settings, and parameter modification suggestions for uplink interference, or co-channel interference detection results, co-channel interference detection location, interfering cell ID, and signal strength for co-channel interference. If co-channel interference exists, it is recommended to deploy different frequency points near the detection area.

[0096] In some embodiments, such as Figure 4 As shown, the specific process of uplink interference detection may include:

[0097] Step 41: The terminal obtains relevant parameters of the serving cell from the base station, such as basic information like PCI, ECI, and TAC.

[0098] Step 42: The terminal requests the uplink noise floor value of the serving cell at the current moment from the gateway platform based on the relevant parameters of the serving cell.

[0099] Step 43: The gateway platform returns the uplink noise floor value of the serving cell to the terminal at the current moment.

[0100] Step 44: The terminal detects the presence of uplink interference based on the uplink noise floor value of the serving cell at the current time. This detection process can be found in the above embodiments and will not be repeated here.

[0101] Step 45: The terminal obtains the configured power control parameters from the base station.

[0102] Step 46: The terminal analyzes the power control parameters and outputs suggested configurations.

[0103] In some embodiments, such as Figure 5 As shown, the specific process of detecting co-channel interference may include:

[0104] Step 51: The terminal obtains the RSRP and RSRQ of the neighboring cell's same frequency point.

[0105] Step 52: The terminal compares the quality and strength of the co-channel signal from the neighboring cell with the signal from the serving cell to determine whether co-channel interference exists. This determination process can be found in the above embodiments and will not be repeated here.

[0106] Step 53: If co-channel interference exists, obtain the geographical location of the serving cell.

[0107] Step 54: The terminal outputs the co-channel interference detection results.

[0108] Step 55: The terminal reports the location information of the cell with severe co-channel interference and the situation of neighboring cells to the network management platform, and suggests deploying different frequency points near the detection area.

[0109] It should be noted that the interference detection method provided in this application can be executed by an interference detection device or a control module within that interference detection device for executing the interference detection method. This application uses an interference detection device executing the interference detection method as an example to illustrate the interference detection device provided in this application.

[0110] Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of an interference detection device provided in an embodiment of this application. This device is applied to a terminal, such as... Figure 6 As shown, the interference detection device 60 includes:
