Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
Fig. 1 is a flowchart of an interference detection method according to an embodiment of the present invention. The method of this embodiment automatically runs through the communication module, where each step may be performed sequentially according to a sequence as in the flowchart, or multiple steps may be performed simultaneously according to an actual situation, which is not limited herein. The interference detection method provided by the invention comprises the following steps:

step S105, if the first comparison result meets the first preset condition, further judging whether the current network is still in a registration state;
and step S106, if the current network is in the non-registration state, reporting an interference signal.
Through the above embodiment, first, when an instruction to start interference detection is received, whether the current network is in a registration state is judged; then, if the current network is in a registration state, acquiring a first parameter value of a serving cell at preset time intervals; then, calculating the average value of the first parameter values acquired by the latest preset times, and calculating a corresponding first threshold value according to the average value; then, judging whether a first comparison result of the current first parameter value and the first threshold meets a first preset condition or not; then, if the first comparison result meets the first preset condition, further judging whether the current network is still in a registration state; and finally, if the current network is in a non-registration state, reporting an interference signal.
In the present embodiment, it should be noted that, in the prior art, a technical problem that interference existing in a communication network to an uplink signal sent by a communication module to a base station cannot be timely found is considered. Therefore, in the present embodiment, in order to solve the above technical problem, whether the current network is in a registration state is determined when an instruction to start interference detection is received; if the current network is in a registration state, acquiring a first parameter value of a serving cell at preset time intervals; calculating the average value of the first parameter values acquired by the latest preset times, and calculating a corresponding first threshold value according to the average value; judging whether a first comparison result of the current first parameter value and the first threshold meets a first preset condition or not; if the first comparison result meets the first preset condition, further judging whether the current network is still in a registration state; and if the current network is in the non-registration state, reporting an interference signal. The interference of the uplink signal sent by the communication module to the base station in the communication network is timely discovered and reported, and convenience is provided for users to timely know the fault reason and further adopt corresponding measures to solve the problem.
The above steps will be described in detail with reference to specific embodiments.
In step S101, when an instruction to start interference detection is received, it is determined whether or not the current network is in a registered state.
Specifically, when an instruction to start interference detection is received, whether the current network is in a registration state is determined, so that a corresponding interference detection process is performed according to different registration states of the current network. The instruction to start interference detection may be sent by a CPU of the communication device where the communication module is located, for example, the CPU sends the instruction to start interference detection to the communication module through an AT instruction.
In step S102, if the current network is in the registration state, a first parameter value of the serving cell is collected every preset time.
Specifically, the preset time may be set according to an actual application scenario, for example, the preset time is set to 280 milliseconds, and a specific value of the preset time is not limited in this embodiment. The parameter type of the first parameter value may be selected according to the type of the current network, for example, when the current network is a 2G network, the first parameter value includes Received Signal strength rxlevel (rxlevel); when the current network is a 3G network, the first parameter values include a ratio of noise spectral density, EcNo (Received Signal Code Power, RSCP), and Received Signal Code Power (RSCP); when the current network is a 4G network, the first parameter values include Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal to Interference plus Noise Ratio (SINR). As will be understood by those skilled in the art, the parameter type of the first parameter value may also be other parameters capable of characterizing the interference signal of the current serving cell, and the embodiment does not limit the specific parameter type of the first parameter value.
In step S103, a mean value of the first parameter values acquired most recently by a preset number of times is calculated, and a corresponding first threshold value is calculated according to the mean value.
Specifically, the preset number of times may be set according to an actual application scenario, for example, the preset number of times is set to 10 times, and a specific value of the preset number of times is not limited in this embodiment. By calculating the average value of the first parameter values acquired by the latest preset times and calculating the corresponding first threshold value according to the average value, the first threshold value can be dynamically adjusted, so that the interference can be found more timely and effectively.
Optionally, the calculating a corresponding first threshold according to the mean value includes: and calculating a corresponding first threshold according to the average value and preset parameters, wherein the numerical values of the preset parameters can be modified according to received preset parameter modification instructions.
Specifically, the user can adjust the preset parameters by inputting a preset parameter modification instruction according to an actual use scene, so that the interference detection method is more adaptive in actual application. For example, the user may adjust the preset parameters via AT instructions.
In step S104, it is determined whether a first comparison result between the current first parameter value and the first threshold satisfies a first preset condition.
Specifically, if the first comparison result between the current first parameter value and the first threshold satisfies a first preset condition, it indicates that the communication module is in a suspected interference state, and it is necessary to further determine whether the current network is still in a registration state.
In step S105, if the first comparison result satisfies the first preset condition, it is further determined whether the current network is still in the registration state.
Specifically, when the first comparison result meets the first preset condition, whether the current network is still in a registration state is further determined to determine whether interference exists.
In step S106, if the current network is in the unregistered state, an interference signal is reported.
Specifically, the current network is in the unregistered state, which indicates that the communication module is in the interference state at this time, and an interference signal needs to be reported. For example, the communication module reports an interference signal to the CPU of the communication device in which the communication module is located through the AT instruction. Therefore, the interference of the uplink signal sent to the base station by the communication module in the communication network is found and reported in time, and convenience is provided for users to know the fault reason in time and further adopt corresponding measures to solve the problem.
Optionally, the method further comprises:
and step S107, if the current network is recovered to the registration state, returning to the step of collecting the first parameter value of the service cell once every preset time.
Specifically, when the current network is restored from the unregistered state to the registered state, the step of collecting the first parameter value of the serving cell every preset time is returned, and whether the communication module is in the interference state is restarted.
In the embodiment of the invention, when an instruction for starting interference detection is received, whether the current network is in a registration state is judged; if the current network is in a registration state, acquiring a first parameter value of a serving cell at preset time intervals; calculating the average value of the first parameter values acquired in the last preset times, and calculating a corresponding first threshold value according to the average value; judging whether a first comparison result of the current first parameter value and the first threshold meets a first preset condition or not; if the first comparison result meets the first preset condition, further judging whether the current network is still in a registration state; and if the current network is in the non-registration state, reporting an interference signal. The interference of the uplink signal sent by the communication module to the base station in the communication network is timely discovered and reported, and convenience is provided for users to timely know the fault reason and further adopt corresponding measures to solve the problem.

The second threshold may be set according to an actual application scenario, and a specific value of the second threshold is not limited in this embodiment. The parameter type of the second parameter value may be selected according to the type of the current network, for example, when the current network is a 2G network, the second parameter value includes a received signal strength RxLev; when the current network is a 3G network, the second parameter value comprises the RxLev; when the current network is a 4G network, the second parameter value includes a Received Signal Strength Indicator (RSSI). As will be understood by those skilled in the art, the parameter type of the second parameter value may also be other parameters capable of characterizing the interference signal of the current serving cell, and the embodiment does not limit the specific parameter type of the second parameter value.
Step S209, judging whether the frequency point number of the second comparison result meeting the second preset condition is greater than a third threshold, if so, executing step S210, otherwise, turning to step S202;
specifically, when the second comparison result meets that the number of the frequency points of the second preset condition is greater than a third threshold, it is indicated that the serving cell corresponding to the communication module currently has interference of multiple frequency points, and an interference signal needs to be reported; and when the second comparison result meets the second preset condition, the number of the frequency points is not greater than a third threshold, the service cell corresponding to the communication module is indicated to have interference of a few frequency points or no interference, at the moment, the step of judging whether the current network is in a registration state is returned, and the interference detection process is continued.
