Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Example 1
Fig. 1 is a flowchart of an interference detection method according to an embodiment of the present invention. The method of this embodiment automatically operates through the communication module, where each step may be performed sequentially as shown in the flowchart during operation, or may be performed simultaneously according to multiple steps in actual situations, which is not limited herein. The interference detection method provided by the invention comprises the following steps:
step S101, when receiving an instruction for starting interference detection, judging whether the current network is in a registration state;

step S105, if the first comparison result meets the first preset condition, further judging whether the current network is still in a registration state;
step S106, if the current network is in a 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 intervals of preset time; then, calculating the average value of the first parameter values acquired for 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 value 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; finally, if the current network is in a non-registration state, reporting an interference signal.
In this embodiment, it should be noted first that the technical problem that the interference to the uplink signal sent to the base station by the communication module in the communication network cannot be found in time in the prior art is considered. Therefore, in this embodiment, in order to solve the above technical problem, whether the current network is in a registered state is determined by 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 intervals of preset time; calculating the average value of the first parameter values acquired for 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 value 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; if the current network is in a non-registration state, reporting an interference signal. The method and the device realize timely discovery and report of interference on the uplink signal sent to the base station by the communication module in the communication network, and provide convenience for users to timely learn the failure cause and further take corresponding measures to solve the problem.
The above steps will be specifically described in connection with the following embodiments.
In step S101, when an instruction to start interference detection is received, it is determined whether the current network is in a registered state.
Specifically, when an instruction for starting interference detection is received, whether the current network is in a registration state is judged, so that a corresponding interference detection flow is performed according to different registration states of the current network. The instruction for starting 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 for starting interference detection to the communication module through an AT instruction.
In step S102, if the current network is in the registration state, the 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 ms, and the 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 a received signal strength RxLev (RECEIVED SIGNAL LEVEL, RXLEV); when the current network is a 3G network, the first parameter values include a ratio of noise spectrum density EcNo (ratioofenergy per modulating bit to the noise SPECTRAL DENSITY, ecNo) and a received signal Code Power RSCP (RECEIVED SIGNAL Code Power, RSCP); when the current network is a 4G network, the first parameter values include a reference signal received Power RSRP (REFERENCE SIGNAL RECEIVED Power, RSRP), a reference signal received Quality RSRQ (REFERENCE SIGNAL RECEIVED Quality, RSRQ), and a signal to interference and noise ratio SINR (Signal to Interference plus Noise Ratio, SINR). As will be appreciated by those skilled in the art, the parameter type of the first parameter value may also select other parameters that can characterize the interference signal of the current serving cell, and the specific parameter type of the first parameter value is not limited in this embodiment.
In step S103, a mean value of the first parameter values acquired for the last preset 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 the specific value of the preset number of times is not limited in this embodiment. The first threshold value can be dynamically adjusted by calculating the average value of the first parameter values acquired for the latest preset times and calculating the corresponding first threshold value according to the average value, so that the interference can be more timely and effectively found.
Optionally, the calculating the corresponding first threshold according to the average value includes: and calculating a corresponding first threshold according to the average value and the preset parameter, wherein the numerical value of the preset parameter can be modified according to the received preset parameter modification instruction.
Specifically, the user can adjust the preset parameters by inputting the preset parameter modification instruction according to the 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 the first comparison result between the current first parameter value and the first threshold value meets a first preset condition.
Specifically, if the current first comparison result between the first parameter value and the first threshold meets a first preset condition, it indicates that the communication module is in a suspected interference state at this time, and it needs to be further confirmed whether the current network is still in a registration state.
In step S105, if the first comparison result meets 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, further judging whether the current network is still in a registration state or not so as to confirm whether interference exists or not.
In step S106, if the current network is in a non-registration state, an interference signal is reported.
Specifically, the current network is in a non-registration state, which indicates that the communication module is in an 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 where the communication module is located through an AT instruction. Therefore, the interference on the uplink signal sent to the base station by the communication module in the communication network is timely found and reported, and convenience is brought to users for timely knowing the failure cause and further taking corresponding measures to solve the problem.
Optionally, the method further comprises, after:
Step S107, if the current network is restored to the registration state, the step of collecting the first parameter value of the serving cell at intervals of preset time is returned.
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 once every preset time is returned, and whether the communication module is in the interference state is restarted.
In the embodiment of the invention, when receiving the instruction for starting interference detection, judging whether the current network is in a registration state or not; if the current network is in a registration state, acquiring a first parameter value of a serving cell at intervals of preset time; calculating the average value of the first parameter values acquired for 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 value 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; if the current network is in a non-registration state, reporting an interference signal. The method and the device realize timely discovery and report of interference on the uplink signal sent to the base station by the communication module in the communication network, and provide convenience for users to timely learn the failure cause and further take corresponding measures to solve the problem.

The second threshold may be set according to an actual application scenario, and the 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 indication, RSSI, (RECEIVED SIGNAL StrengthIndicator, RSSI). As will be appreciated by those skilled in the art, the parameter type of the second parameter value may also be selected to be other parameters that can characterize the interference signal of the current serving cell, and the specific parameter type of the second parameter value is not limited in this embodiment.

Wherein i is the ith acquisition, i >10.

Specifically, when the current network is in a non-registration state, an interference detection flow in the non-registration state is entered, frequency sweep is started, rxLev of a swept point is obtained, and the RxLev is compared with a corresponding second threshold RxLev th2 to obtain a second comparison result. The second threshold RxLev th2 may be set according to an actual application scenario, for example, the value range of the second threshold RxLev th2 is set to 0 to 63, the default value is 45, and the specific value of the second threshold RxLev th2 is not limited in this embodiment.
