Description

Technical Field

[0001] This application relates to the field of private network communication, and in particular to a method for determining the interference status of interference signals, a mobile terminal, and a storage medium. Background Technology

[0002] In team collaboration scenarios such as industrial production, security patrols, and property management, walkie-talkies are widely used as real-time voice communication tools. Their high immediacy and ease of operation make them core equipment for ensuring the transmission of team instructions and task coordination. However, walkie-talkie usage environments are complex and varied, requiring users to adjust device operating parameters based on the interference levels in the current environment to reduce the impact of interference.

[0003] Currently, existing technical solutions mainly rely on a single parameter to evaluate interference signals in the environment. Specifically, existing technical solutions often use the signal-to-noise ratio (SNR) to measure the strength of interference signals in the current channel.

[0004] However, the signal-to-noise ratio (SNR) only reflects the ratio of total signal power to total noise power, and cannot reflect the frequency domain location and bandwidth characteristics of the interfering signal. In practical applications, even with the same SNR, the impact of co-channel interference and adjacent channel interference on service signals can differ significantly. Therefore, single-parameter evaluation schemes are no longer suitable for the accurate evaluation of interference signals in complex environments. Summary of the Invention

[0044] Figure 1a This is one of the flowcharts illustrating a method for determining the interference state of an interference signal, provided in an embodiment of this application. In one embodiment, the method is applied to a first device, and the method includes: S101-S106.

[0045] S101. Obtain the spectrum of the target interference signal within the target channel.

[0046] The target channel is used to transmit service signals. Among the target channel and other channels, including adjacent channels, there exists at least one interfering signal that affects the service signals. This at least one interfering signal includes the target interfering signal.

[0047] The first device can be either the sender or the receiver.

[0048] S102. Obtain the frequency offset between the service signal and the target interference signal, the bandwidth of the target channel, and the field strength of the service signal.

[0049] The frequency offset is the difference between the frequency of the service signal and the frequency of the target interference signal. In this embodiment, the field strength of the service signal is obtained by measuring with a measuring instrument. The field strength of the service signal is the power corresponding to the service signal.

[0055] in, The perceived energy value of the interference signal. For interference signal strength parameters, This refers to the frequency offset between the service signal and the interference signal. Let be the bandwidth of the channel, and 'a' be the compensation value.

[0056] It should be noted that the compensation value 'a' was set by the applicant based on practical experience. This application does not impose any restrictions on it.

[0057] S105. Calculate the signal-to-noise difference of the target channel based on the field strength and sensing energy value.

[0058] The field strength of the service signal is the power value of the service signal.

[0059] In one embodiment, the formula for calculating the signal-to-noise difference is:

[0060] Where RSSI is the field strength of the service signal. This represents the perceived energy value of the interference signal.

[0061] Please see Figure 1b , Figure 1b This diagram illustrates a signal-to-noise difference calculation method provided in an embodiment of this application. Fc represents the service frequency of the current channel signal.

[0062] S106. Determine the interference status of the target interference signal based on the frequency offset and signal-to-noise difference.

[0063] In this embodiment, the interference state of the target interference signal is further determined by fusing the frequency offset and the signal-to-noise difference. The specific determination process is described in detail in the embodiments of this application. It will not be repeated here.

[0064] This application provides a method for determining the interference state of an interference signal. The method is applied to a first device and includes: acquiring a spectrum diagram of a target interference signal of a service signal within a target channel; acquiring the frequency offset between the service signal and the target interference signal, the bandwidth of the target channel, and the field strength of the service signal; extracting spectral parameters of the target interference signal from the spectrum diagram; calculating a sensed energy value of the target interference signal based on the spectral parameters, the frequency offset, and the bandwidth, wherein the sensed energy value characterizes the strength of the target interference signal; calculating the signal-to-noise ratio (SNR) of the target channel based on the field strength and the sensed energy value; and determining the interference state of the target interference signal based on the frequency offset and the SNR. Therefore, this application obtains the spectrum diagram of the target interference signal of a service signal within a target channel, the frequency offset between the service signal and the target interference signal, the bandwidth of the target channel, and the field strength of the service signal. Then, the spectral parameters of the target interference signal are extracted from the spectrum diagram, and the sensed energy value of the target interference signal is calculated based on the spectral parameters, the frequency offset, and the bandwidth. The sensed energy value characterizes the strength of the target interference signal. Furthermore, the signal-to-noise ratio (SNR) of the target channel is calculated based on the field strength and sensing energy value. Finally, the interference state of the target interference signal is determined based on the frequency offset and the SNR. Therefore, the technical solution of this application integrates the spectral parameters of the target interference signal, the frequency offset between the service signal and the target interference signal, the bandwidth of the target channel, and the field strength of the service signal to evaluate the interference state of the target interference signal. The spectral parameters of the target interference signal reflect its intensity characteristics, and the frequency offset between the service signal and the target interference signal characterizes their frequency positional relationship. This solution can meet the needs of accurate interference signal evaluation in complex environments, significantly improving the accuracy of interference assessment.

[0065] In one embodiment, S101 specifically includes the following steps: S1011-S1015.

[0066] S1011. Obtain multiple frequency points to be sensed for the target channel.

[0067] It should be noted that the multiple frequency points to be sensed were pre-set by the applicant. Please refer to [link / reference]. Figure 1c , Figure 1cThis application provides a sensing sequence planning diagram for frequency points to be sensed. Specifically, in this application embodiment, adjacent channel planning, congestion planning, and spurious signal planning are set sequentially according to the sensing order. The adjacent channel planning sets six frequency points to be sensed: current service frequency ±12.5KHz, current service frequency ±25KHz, and current service frequency ±50KHz. The congestion planning sets six frequency points to be sensed: current service frequency ±1MHz, current service frequency ±5MHz, and current service frequency ±10MHz. For spurious signal planning, the frequency points to be sensed are set according to the following formula in this application embodiment:

[0068] in, The local oscillator frequency, The first intermediate frequency (IF) of the first device is used for calculation, and n and m are for calculation purposes only and have no practical meaning. For example, when m=1, n takes integers from 0 to 9, and according to the above spurious frequency planning calculation formula, there are a total of 19 frequency points to be sensed. When m=2 or 3, n takes integers from 0 to 9, and according to the above spurious frequency planning calculation formula, there are a total of 36 frequency points to be sensed. In the embodiments of this application, frequency points within ±30% of the service frequency point are selected for sensing tests.

[0069] In one embodiment, if the first device has a second intermediate frequency, the following six frequency points to be sensed need to be added to the spurious planning points:

[0070] in, The second intermediate frequency of the first device. This refers to the frequency of the service signal.

[0071] S1012. Calculate the frequency offset between each frequency point and the frequency point of the service signal among multiple frequency points to be sensed.

[0072] In this embodiment, the offset between each frequency point to be sensed and the frequency point of the service signal is calculated.

[0073] S1013, Execute the interference signal detection process.

[0074] The interference signal detection process includes detecting interference signals for each of the multiple target frequency points in ascending order of frequency offset.

[0075] In one embodiment, S1013 specifically includes the following steps: S10131-S10132.

[0076] S10131. Adjust the local oscillator frequency according to the first frequency to be sensed.

[0077] S10132. Based on the local oscillator frequency, perform interference signal detection on the first frequency point to be sensed.

[0078] It should be noted that S10131-S10132 will be explained in detail below.

[0079] like Figure 1d As shown, Figure 1d This is a superheterodyne architecture diagram for sensing the environment provided in an embodiment of this application. In this embodiment, the local oscillator frequency is modified so that the receiving frequency of the device is the first frequency to be sensed, and then the signal of the first frequency to be sensed is received based on the local oscillator frequency, thereby realizing the detection of interference signals.

[0080] like Figure 1e As shown, Figure 1e This is a diagram of a zero-IF or ultra-low IF architecture for sensing the environment, provided in an embodiment of this application. The interference signal interference state determination method in this embodiment is also applicable to the zero-IF or ultra-low IF architecture. Specifically, by changing the local oscillator frequency of the zero-IF chip, the receiving frequency of the device is made to the first frequency to be sensed. Then, based on this local oscillator frequency, the signal of the first frequency to be sensed is received, thereby achieving the detection of the interference signal.

[0081] It should be noted that, regardless of whether it is a 1-to-1 scenario or a 1-to-N scenario, the embodiments of this application utilize idle time slots to detect interference signals. For example... Figures 1f-1 to 1f-3 As shown, Figure 1f-1 This is one of the idle time slot time planning diagrams provided in the embodiments of this application. Figure 1f-2 This is a one-to-one scenario communication diagram provided in an embodiment of this application. Figure 1f-3 This application provides a 1-to-N scenario communication diagram. Time slot 1 is used for service calls, and time slot 2 is an idle time slot used to detect interference signals in the surrounding environment or send short messages. Specifically, in this application embodiment, the idle time slot is used to detect interference signals. This allows for real-time detection of interference signals in the surrounding environment without affecting normal service functions, such as voice call functionality. In this application embodiment, the idle time slot is divided into multiple fixed structures. Each fixed structure is divided into three parts: a guard time slot, a local oscillator (LO) switching, and data acquisition and calculation. The LO switching part is used for adjusting the local oscillator frequency. The data acquisition and calculation part is used for interference signal detection and to generate an interference signal spectrum. It should be noted that the applicant sets the time length of each fixed structure based on practical experience. Preferably, the time length of each fixed structure is 10ms. Specifically, the guard time slot occupies 1ms, the LO switching occupies 5ms, and the data acquisition and calculation occupies 4ms.

[0082] In another embodiment, please refer to Figure 1g , Figure 1gThis is a second idle time slot time planning diagram provided in the embodiments of this application. In this embodiment, the idle time slot is divided into 5 small parts, including protection time slot 1, LO switching 1 and acquisition calculation, LO switching 2 and protection time slot 2. The time length occupied by each small part is set by the applicant based on actual experience. Preferably, protection time slot 1 occupies 7ms, LO switching 1 occupies 5ms, acquisition calculation occupies 6ms, LO switching 2 occupies 5ms, and protection time slot 2 occupies 7ms.

[0083] Please see Figure 1h , Figure 1h This is the third idle time slot time planning diagram provided in the embodiments of this application.

[0084] In this embodiment, the idle time slots are used both to collect environmental interference signals and for inter-device SMS handshake coordination. Time slot multiplexing of idle time slots can improve spectrum utilization efficiency.

[0085] like Figure 1i As shown, Figure 1i This is a flowchart illustrating a signal sensing process provided in an embodiment of this application. The sensing range setting has been described in detail in S1011 above, and will not be repeated here. This embodiment of the application uses a 30ms idle time slot to sense and collect interference signals from the environment in real time and stores them in a signal storage repository.

[0086] S1014. When an interference signal is detected at the frequency point to be sensed, the interference signal detection process is stopped.

[0087] In this application, when interference information is detected at a frequency point to be sensed, the interference signal detection process is immediately stopped. Typically, multiple interference frequencies exist on the target channel. The closer the interference signal's frequency is to the service frequency, the greater its impact on the service signal. In this embodiment, upon sensing the interference signal closest to the service frequency, the interference signal detection process is immediately stopped.

[0088] S1015. Collect the interference signals detected at the frequency point to be sensed to generate a spectrum diagram of the target interference signal.

[0089] In this embodiment of the application, interference signals detected at the frequency to be sensed are collected, and corresponding spectrum diagrams are generated.

[0090] In one embodiment, S106 specifically includes the following steps: S1061-S1062.

[0091] S1061. Determine the frequency offset weight level of the target interference signal based on the frequency offset.

[0092] It should be noted that the frequency offset weight level represents the weight of the interference signal's influence on the service signal. In this embodiment, the frequency offset weight level is divided into two levels: a first frequency offset weight level and a second frequency offset weight level. Specifically, when the frequency offset is greater than 100 kHz, the frequency offset weight level is set to the second frequency offset weight level. When the frequency offset is less than or equal to 100 kHz, the frequency offset weight level is set to the first frequency offset weight level.

[0093] S1062. Determine the interference status based on the frequency offset weight level and the signal-to-noise difference.

[0094] In this embodiment, the interference is divided into a default interference state, a first interference state, and a second interference state, in ascending order of the degree of interference. The second interference state represents the greatest degree of interference.

[0095] In one embodiment, S1062 specifically includes the following steps: S10621-S10622.

[0096] S10621. If the frequency offset weight level is the first frequency offset weight level and the signal-to-noise difference is greater than the first threshold, then the interference state is determined to be the second interference state. S10622. If the frequency offset weight level is the second frequency offset weight level and the signal-to-noise difference is greater than the first threshold, then the interference state is determined to be the first interference state.

[0097] It should be noted that S10621-S10622 will be explained in detail below.

[0098] The first threshold is determined by the demodulation threshold and the margin. The demodulation threshold is defined as being higher than the lowest decoding threshold for the noise floor. The margin is an empirical value defined by the applicant. When the interference state belongs to neither the first interference state nor the second interference state, the interference state is the default interference state.

[0099] Furthermore, the higher the frequency offset weight level, the greater the interference of the target interference signal on the service signals within the target channel. The interference state corresponding to the first frequency offset weight level is the second interference state. The first frequency offset weight level is the highest frequency offset weight level. Conversely, the lower the frequency offset weight level, the less interference the target interference signal causes on the service signals within the target channel. The interference state corresponding to the second frequency offset weight level is the first interference state. The second frequency offset weight level is lower than the first frequency offset weight level.

[0100] In one embodiment, after S106 described above, the method further includes S107.

[0101] S107. Based on the interference state, execute an anti-interference strategy that matches the interference state.

[0102] In one example, S107 specifically includes the following steps: S1071.

[0103] S1071. When the interference state is the first interference state, send a first SMS message to the second device, and / or increase the receiving link gain of the first device. The first SMS message is used to instruct the second device to increase the transmitting power.

[0104] In this application, the second device can be either a sender or a receiver. When the first device is the sender, the second device is the receiver. When the first device is the receiver, the second device is the sender. When the first device and the second device are communicating, they are both senders and receivers to each other. Therefore, both the first device and the second device can implement the technical solution of this application.

[0105] Please see Figure 1j , Figure 1j This diagram illustrates the effect of providing transmit power according to an embodiment of this application. As shown in Figure 1, in this embodiment, by increasing the receive link gain of the first device and / or increasing the transmit power of the second device, the sensitivity is effectively reduced, thereby reducing the impact of interference signals on service signals.

[0106] In another embodiment, the above-mentioned S107 further includes the following steps: S1072-S1075.

[0107] S1072. When the interference state is the second interference state, select the first channel frequency point from the preset multiple channel frequency points.

[0108] It should be noted that when the interference is at the second level, the interference is quite severe, and increasing the receive link gain and / or increasing the transmit power cannot eliminate the effects of the interference signal. Therefore, channel switching is necessary.

[0109] Please see Figure 1k , Figure 1k This diagram illustrates the effect of providing transmit power according to an embodiment of this application. As shown in Figure 1k, this embodiment effectively reduces the impact of interference signals on service signals through channel switching.

[0110] In one embodiment, each of the preset multiple channel frequency points corresponds to a noise floor value, and the above-mentioned S1072 further includes the following steps: S10721.

[0111] S10721. Select the channel frequency with the smallest noise floor value from a set of preset channel frequency points, and use the channel frequency with the smallest noise floor value as the first channel frequency point.

[0112] It should be noted that when multiple channel frequencies with the lowest noise floor exist simultaneously, in this embodiment of the application, the channel frequency closest to the frequency of the service signal is selected as the first channel frequency to reduce the time spent by the first device in performing channel switching.

[0113] S1073, Send a second SMS message to the second device.

[0114] The second SMS message includes the first channel frequency. The second SMS message is used to instruct the second device to perform channel switching based on the first channel frequency.

[0115] In this embodiment of the application, after the first device determines the first channel frequency point to be switched, it needs to notify the second device to perform channel switching simultaneously based on the first channel frequency point via SMS.

[0116] S1074, Receive the first receipt message from the second device.

[0117] The first receipt message is a confirmation message from the second device to the second SMS message.

[0118] S1075. Based on the first receipt message, establish a communication connection with the second device using the first channel frequency.

[0119] In this embodiment, upon receiving the first receipt message, a communication connection is established with the second device based on the first channel frequency. In other words, the first device and the second device switch channels and re-establish communication.

[0120] In one embodiment, after S106 described above, the method further includes S108.

[0121] S108. Report the interference status to the third device so that the third device can generate an anti-interference strategy that matches the interference status.

[0122] It should be noted that in a 1-to-N communication scenario, the applicant pre-selects one device from the N devices as a third device. The other devices need to measure and sense interference signals in real time and report the measured interference status to the third device. The third device then summarizes and analyzes the multiple reported interference statuses to generate corresponding anti-interference strategies.

[0123] In one embodiment, after S108, the method further includes S109-S110.

[0124] S109. Receive a third SMS message from a third device.

[0125] S110, Increase transmission power based on third SMS message, and / or increase receiver link gain.

[0126] It should be noted that S109-S110 will be explained in detail below.

[0127] The third device summarizes and analyzes the multiple reported interference states and then sends a third SMS message to the first device. This third SMS message instructs the first device to increase its transmit power and / or increase its receive link gain.

[0128] In one embodiment, after S108, the method further includes S111-S112.

[0129] S111, Receive a fourth SMS message from a third device.

[0130] The fourth SMS message includes the second channel frequency. The second signal frequency is calculated by the third device. The specific calculation process will be described in detail in later embodiments of this application. It will not be repeated here.

[0131] S112. Establish a communication connection with the second device based on the second channel frequency.

[0132] It should be noted that in a one-to-N communication scenario, when a signal switching is required, all devices must switch simultaneously. It is not possible for only some devices to perform channel switching.

[0133] Please see Figure 11 , Figure 11 This application provides a flowchart for a 1-to-N interference signal processing method. First, the device has its sensing frequency set at the factory. The specific method for setting the sensing frequency is described in S101 above. Next, the device waits for an idle state during a call and senses environmental signals through time slot 2. Time slot 2 is an idle time slot. Then, the device reports the interference status of the sensed interference signal to device A via SMS, where device A acts as a third device. Device A summarizes and analyzes all reported interference statuses and executes corresponding actions. Specific analysis steps are described in S301-S303 above. It should be noted that... Figure 11In the diagram, state 1 is the first interference state, state 2 is the second interference state, and state 3 is the default interference state. When the interference state is state 1, device A sends a power adjustment command to all nodes and / or receives an attenuation adjustment command. All nodes, upon receiving the corresponding command, need to send a confirmation response to device A. If any node fails to send a confirmation response, device A resends the command and marks the abnormal node. After device A receives confirmation responses from all nodes, all devices adjust their transmit power and / or receive attenuation, entering a high-power, high-sensitivity operating mode for the entire network. When the interference state is state 2, device A calculates the optimal switching frequency and sends a frequency switching command to all nodes. All nodes, upon receiving the corresponding command, need to send a confirmation response to device A. If any node fails to send a confirmation response, device A resends the command and marks the abnormal node. After device A receives confirmation responses from all nodes, the entire network synchronously switches channels according to the optimal frequency and re-establishes communication. It should be noted that, regardless of whether it is the first device, the second device, or the third device, after the communication ends, they all restore the default operating parameters and enter the default operating state.

[0149] S301, Receive interference status reported by at least one first device.

[0150] It should be noted that in a 1-to-N scenario, since the first and second devices are either senders or receivers to each other, in practical applications, all N devices will simultaneously perform interference detection and report the interference status to the third device.
