In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

As shown in Figure 1, it is a flow chart of the steps of the testing method of the NB-IoT terminal in the embodiment of the present invention, the method includes the following steps:

Step 101: Obtain the network coverage signal strength at the location where the NB-IoT terminal is to be installed.

In this step, specifically, when obtaining the network coverage signal strength at the location where the NB-IoT terminal is to be installed, the NB-IoT test terminal with a communication function that is pre-placed at the location to be installed can be measured to obtain the The reference signal received power RSRP value at the location to be installed, and then determine the network coverage signal strength at the location to be installed according to the RSRP value at the location to be installed measured by the NB-IoT test terminal.

Specifically, the RSRP value measured by the NB-IoT test terminal includes the RSRP value of the serving cell accessed by the NB-IoT test terminal in the current wireless environment and the RSRP value of the neighboring cell of the serving cell.

Specifically, the NB-IoT test terminal has the function of sending the measured RSRP value to the microcomputer controller, which can solve the problem that ordinary NB-IoT terminals cannot feed back the measured RSRP, which makes the NB-IoT test terminal 2 placed When it is at the location to be installed, such as the top of the light pole of the smart street lamp, the wellhead of the smart manhole cover, the ceiling slot of the smart smoke detector, etc., the NB-IoT test terminal can measure the RSRP value at the location to be installed in the current wireless environment. At this time, the NB-IoT test terminal can send the measured RSRP value to the connected microcomputer controller, so that the network coverage signal strength at the location to be installed can be determined through the microcomputer controller.

In addition, specifically, in order to facilitate the measurement of the RSRP value at the location to be installed, an antenna can be directly placed at the location to be installed, and then the NB-IoT test terminal and the antenna are connected through a feeder line, thereby realizing the measurement of the RSRP value at the location to be installed .

In addition, specifically, the microcomputer controller mainly refers to an embedded host, and may also be a portable computer and an intelligent terminal; in addition, specifically, in this embodiment, the microcomputer controller may also be configured with a display, a touch screen as a human-computer interaction input and output device /keyboard, so that the user can interact with the microcomputer controller.

In addition, specifically, when determining the network coverage signal strength at the location to be installed, the maximum RSRP value among the RSRP values measured multiple times by the NB-IoT test terminal within a preset period of time may be determined as the maximum RSRP value at the location to be installed. The network coverage signal strength can also be determined as the network coverage signal strength at the location to be installed by taking the average value of the highest preset RSRP values among the RSRP values obtained by multiple measurements of the NB-IoT test terminal in order from large to small. , that is, the specific manner of determining the network coverage signal strength is not specifically limited here.

Step 102: Obtain the receiving sensitivity of the NB-IoT terminal to be installed.

In this step, specifically, it is also necessary to obtain the receiving sensitivity of the NB-IoT terminal to be installed, so that the NB-IoT terminal to be installed can be determined according to the receiving sensitivity of the NB-IoT terminal to be installed and the network coverage signal strength at the location to be installed. -Whether the IoT terminal is available.

Step 103: Detect whether the NB-IoT terminal to be installed is an available terminal according to the network coverage signal strength at the location to be installed and the receiving sensitivity of the NB-IoT terminal to be installed.

In this step, specifically, when detecting whether the NB-IoT terminal to be installed is an available terminal according to the network coverage signal strength at the location to be installed and the receiving sensitivity of the NB-IoT terminal to be installed, it may be detected that the NB-IoT terminal to be installed When the receiving sensitivity of the installed NB-IoT terminal is less than the network coverage signal strength, determine that the NB-IoT terminal to be installed is an available terminal; when it is detected that the receiving sensitivity of the NB-IoT terminal to be installed is greater than or equal to the network When covering the signal strength, it is determined that the NB-IoT terminal to be installed is an unavailable terminal.

In this way, before the NB-IoT terminal to be installed is installed, by comparing the network coverage signal strength of the installation site with the receiving sensitivity of the NB-IoT terminal to be installed, it is possible to detect whether the NB-IoT terminal to be installed is available at the installation site, thereby It improves the success rate of NB-IoT terminals to be installed after installation, reduces the number and difficulty of post-maintenance of NB-IoT terminals, shortens the overall processing time and workload, and saves costs.

In addition, specifically, obtaining the receiving sensitivity of the NB-IoT terminal to be installed may include the following steps:

Step D1: Control the NB-IoT terminal to be installed to only receive the transmission signal of the preset NB-IoT test base station with adjustable signal transmission power.

Specifically, the pre-set NB-IoT test base station has all NB-IoT air interface channels and channel configurations, can be identified by NB-IoT terminals, reside on it, and initiate an attach or access process on it, that is, it can be used by NB-IoT Terminal attachment and access. In addition, the implementation of NB-IoT test base station can be to build NB-IoT test base station through a set of chips (baseband integrated circuit (abbreviated as BBIC) and radio frequency integrated circuit (abbreviated as RFIC)), or through a computer with base station program software installed (also It can form an open source NB-IoT test base station for smart terminals and embedded terminals, etc.) plus a radio frequency (software radio) platform. Of course, the NB-IoT test base station can also be implemented in other ways of combining software and hardware, so I won’t go into details here.

In this step, when controlling the NB-IoT terminal to be installed to only be able to receive the signal transmitted by the NB-IoT test base station, the NB-IoT terminal to be installed can be placed in a shielding box that can shield external signals, and the NB-IoT The signal emitted by the IoT test base station is guided into the shielding box, so that the NB-IoT terminal to be installed in the shielding box can only receive the signal emitted by the NB-IoT test base station guided into the shielding box, but cannot receive the signal outside the shielding box live network signal.

Step D2: controlling and adjusting the signal transmission power of the NB-IoT test base station to a second target power value based on the first target power value.

In this step, specifically, the first target power value is the maximum signal transmission power corresponding to when the NB-IoT test base station cannot receive the random access message sent by the NB-IoT terminal to be installed when it is started value, and when the signal transmission power of the NB-IoT test base station is the second target power value, the NB-IoT test base station can receive the random access request message sent by the NB-IoT terminal to be installed when it starts .

Wherein, when controlling and adjusting the signal transmission power of the NB-IoT test base station to the second target power value based on the first target power value, it may first control and adjust the signal transmission power of the NB-IoT test base station to the second target power value A target power value; then control the NB-IoT test base station to increase the preset power value every preset period of time based on the first target power value, wherein the number of times the preset power value is increased is preset number of times; and detect whether the NB-IoT test base station receives the random access request message sent by the NB-IoT terminal to be installed when the NB-IoT test base station increases the preset power value each time; when detected When the NB-IoT test base station receives the random access request message sent by the NB-IoT terminal to be installed, it records the power value at the corresponding moment; and obtains the average value of all the recorded power values, and puts the average value is determined as the second target power value.

Of course, when it is detected that each time the NB-IoT test base station increases the preset power value, the NB-IoT test base station cannot receive the random access request message sent by the NB-IoT terminal to be installed, The NB-IoT terminal to be installed can be determined as a suspected unavailable terminal; at this time, it can be controlled to adjust the signal transmission power of the NB-IoT test base station to a normal power value, and detect whether the NB-IoT test base station receives The random access request message sent by the NB-IoT terminal to be installed; at this time, when it is detected that the signal transmission power of the NB-IoT test base station is a normal power value, the NB-IoT test base station receives the The random access request message sent by the NB-IoT terminal to be installed determines that the NB-IoT terminal to be installed is determined to be an unavailable terminal.

Specifically, when controlling and adjusting the signal transmission power of the NB-IoT test base station to the first target power value, the microcomputer controller connected to the NB-IoT test base station may first control and adjust the signal transmission of the NB-IoT test base station The power is the minimum value (set the signal transmission power parameter nrs-Power-r13), and then detect whether the NB-IoT test base station has received the random access request "RRC Connection Request" message sent by the terminal to be installed through the microcomputer controller; at this time , if it is detected that the NB-IoT test base station receives a random access request message, it means that the receiving sensitivity of the NB-IoT terminal to be installed in this environment is not the highest receiving sensitivity, that is, the NB-IoT test base station transmits at this time If the signal is still too strong, you can turn off the power of the NB-IoT test base station at this time, then connect an attenuator (such as a 20dB attenuator) to the signal output of the NB-IoT test base station, and restart the NB-IoT test base station, and repeat the check Whether the NB-IoT test base station receives the random access request message until it is detected that the NB-IoT test base station cannot receive the random access request message.

In addition, specifically, when controlling the NB-IoT test base station based on the first target power value and increasing the preset power value every preset period of time, the microcomputer controller can be manually controlled, or the microcomputer controller can automatically control, Control the transmission signal power of the NB-IoT test base station to increase the preset power value (for example, 2dB) every preset period of time (for example, every 15s).

In addition, specifically, the preset number of times may be 3 times. Of course, the value of the preset number of times is not specifically limited here.

In addition, specifically, the normal power value of the signal transmission power is the corresponding power value when all NB-IoT terminals without failure can access and attach when the NB-IoT test base station transmits signals, for example, it may be 12dBm.

Step D3: Control the preset NB-IoT test terminal with communication function to only be able to receive the signal transmitted by the NB-IoT test base station, and obtain the signal transmission of the NB-IoT test terminal at the NB-IoT test base station The measured RSRP value when the power is the second target power value.

In this step, specifically, when controlling and adjusting the signal transmission power of the NB-IoT test base station to the second target power value, control the NB-IoT test terminal to only receive the transmission signal of the NB-IoT test base station, that is, control the NB- The wireless environment where the IoT test terminal receives the signal is the same as the wireless environment where the NB-IoT terminal to be installed is located. At this time, the measured signal transmission power of the NB-IoT test terminal at the NB-IoT test base station is the second target power value. to the RSRP value. Specifically, since the NB-IoT test terminal can only receive the signal transmitted by the NB-IoT test base station, that is, the same environment as the NB-IoT terminal to be installed, the RSRP value measured by the NB-IoT test terminal is equivalent to the The RSRP value measured by the NB-IoT terminal is installed. At this time, through the communication function of the NB-IoT test terminal, the RSRP value measured by the NB-IoT test terminal can be obtained, which is equivalent to obtaining the RSRP value of the NB-IoT terminal to be installed. The measured RSRP value.

In addition, specifically, in this embodiment, the NB-IoT test terminal can be placed in the shielding box at the same time, so that the NB-IoT test terminal can only receive the signal transmitted by the NB-IoT test base station; in addition, if the space in the shielding box is small small, you can first shut down the NB-IoT terminal to be installed and take it out of the shielding box, and then place the NB-IoT test terminal in the shielding box to receive the signal transmitted by the NB-IoT test base station; in addition, you can also directly Place the NB-IoT test terminal outside the shielding box, and then receive the signal inside the shielding box through the receiving antenna placed in the shielding box. That is, the specific manner in which the NB-IoT test base station can only receive signals transmitted by the NB-IoT test base station is not specifically limited here.

In addition, specifically, when obtaining the RSRP value measured by the NB-IoT test terminal when the signal transmission power of the NB-IoT test base station is the second target power value, the microcomputer controller can receive the RSRP value sent by the NB-IoT test terminal. Obtain the RSRP value.

Step D4: Determine the RSRP value measured by the NB-IoT test terminal as the receiving sensitivity of the NB-IoT terminal to be installed.

In this step, specifically, after obtaining the RSRP value sent by the NB-IoT test terminal, determine the RSRP value measured by the NB-IoT test terminal as the receiving sensitivity of the NB-IoT terminal to be installed.

In this way, by controlling the transmission signal power of the NB-IoT test base station in a signal isolation environment, the second target power value when the NB-IoT test base station receives the random access request message sent by the NB-IoT terminal to be installed is determined, The RSRP value measured by the NB-IoT test terminal under the same signal scenario is used as the receiving sensitivity of the NB-IoT terminal to be installed, and the measurement of the receiving sensitivity of the NB-IoT terminal to be installed is realized, so that the user can be based on the NB-IoT terminal to be installed. - For the receiving sensitivity of IoT terminals, refer to the network coverage signal strength at the installation site, and select NB-IoT terminals suitable for the installation scenario.

In addition, further, in this embodiment, after detecting that the NB-IoT terminal to be installed is an available terminal, the terminal information of the NB-IoT terminal to be installed may also be acquired, wherein the terminal information includes the NB-IoT terminal to be installed International Mobile Subscriber Identity (IMSI for short) and International Mobile Equipment Identity (IMEI for short) of the terminal.

Specifically, when obtaining the terminal information of the NB-IoT terminal to be installed, it is possible to control and adjust the signal transmission power of the NB-IoT test base station to a normal power value, and obtain the NB-IoT terminal to be installed. The identity recognition response message when the NB-IoT test base station is on, wherein the identity recognition response message carries the IMSI and IMEI of the NB-IoT terminal to be installed.

In addition, specifically, in this embodiment, when controlling and adjusting the signal transmission power of the NB-IoT test base station to a normal power value, the installation location of the NB-IoT terminal to be installed can be acquired through a preset GPS module.

In this way, in this embodiment, by obtaining the network coverage signal strength at the location to be installed of the NB-IoT terminal to be installed and the receiving sensitivity of the NB-IoT terminal to be installed, the relationship between the network coverage signal strength at the location to be installed and the NB-IoT terminal to be installed can be obtained. -Comparing the receiving sensitivity of IoT terminals to determine whether the NB-IoT terminal to be installed is an available terminal, thereby improving the success rate of service activation during terminal installation, and reducing the maintenance amount of NB-IoT terminals in the later period, and reducing operator maintenance The workload of personnel reduces the maintenance cost.
