Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a method and system for monitoring LTE network air interface signaling and network status. Background Art

[0002] Private LTE is mainly used in subways, railways and other scenarios, carrying train driver voice communications and train control information, and the network status is very important. The private LTE frequency band is 1785~1805MHz, and it adopts TDD working mode.

[0003] At present, the private network LTE air interface monitoring mainly uses a laptop to connect the test terminal and GPS module through a data cable. The data cable often has poor contact or shakes during the test, resulting in test interruption, affecting test continuity and reducing test efficiency. In addition, the data cable connection method makes the entire system very redundant. It can only be tested on the vehicle, not on foot or at a fixed point, and cannot be used in rainy or dusty environments, greatly limiting its scope of use.

[0004] Currently, commonly used monitoring tools are complex to operate and require operators to have a high level of communication knowledge. Private LTE networks are small in scale, with relatively few maintenance personnel. The skills of these personnel are somewhat different from those of operator maintenance personnel. The complex operation methods limit the user groups of the tools and indirectly reduce the professionalism of the tools.

[0005] Whether it is a subway or a railway, there are multiple tunnels in the scene. The existing test equipment uses GPS to provide location information. GPS cannot receive signals in the tunnel, and thus cannot provide location information, which destroys the integrity of the collected data. Using data without location information to locate network problems is extremely inefficient and even impossible to analyze.

[0006] At present, the private network LTE air interface monitoring equipment uses a private network mobile phone as the test terminal. The mobile phone cannot be connected to the roof antenna, and the driver's communication antenna is on the roof, so the current test equipment cannot accurately measure the driver's communication device's perception of the network. In addition, the placement of the mobile phone will have a certain impact on the test results, so the current test equipment has a large measurement fluctuation range, which reduces the accuracy of the test results.

[0007] Currently, private network LTE air interface test equipment does not have the remote positioning function. Once lost, it will cause economic losses. Summary of the invention

[0008] The embodiments of the present application provide a method and system for monitoring LTE network air interface signaling and network status to improve the above problems.

[0009] In order to achieve the above objectives, this application adopts the following technical solutions:

[0010] In the first aspect, an embodiment of the present application proposes an LTE network air interface signaling and network status monitoring method, which is applied to an LTE network air interface signaling and network status monitoring system, wherein the LTE network air interface signaling and network status monitoring system includes a data acquisition computer, a display, an air interface monitoring module, a location information module, a power supply module and a remote positioning module, and the LTE network air interface signaling and network status monitoring method includes: the data acquisition computer controls the air interface monitoring module through the serial port; the air interface monitoring module communicates with the private network LTE base station through the antenna, calculates the private network LTE air interface status data, and sends it to the data acquisition computer; the location information acquisition module collects the longitude and latitude position information and transmits it to the data acquisition computer; the data acquisition computer merges the private network LTE air interface status data and the longitude and latitude position information.

[0011] In combination with the first aspect, in some embodiments, the location information acquisition module includes a GPS module and a gyroscope, and the location information acquisition module collects longitude and latitude location information and transmits it to a data acquisition computer, including: directly collecting longitude and latitude information provided by GPS when receiving GPS signals normally, and transmitting it to the data acquisition computer.

[0012] In combination with the first aspect, in some embodiments, it is characterized in that the method also includes: the gyroscope is automatically corrected according to the GPS information. When entering the tunnel, the processor in the module calculates the state change of the gyroscope and combines the speed, driving direction, altitude, longitude and latitude information before the GPS signal is lost to calculate the longitude and latitude information in the tunnel, and transmits it to the data acquisition computer.

[0013] In combination with the first aspect, in some embodiments, the LTE network air interface signaling and network status monitoring system also includes a private network LTE test antenna interface, and the method also includes: the private network LTE test antenna interface adopts an N-KF interface, and a matching fiberglass full-line antenna is used for fixed-point testing along the track. During on-vehicle testing, the roof antenna is connected through a feeder to measure the network status received by the private network LTE vehicle-mounted station.

[0014] In combination with the first aspect, in some implementations, there are two private network LTE test antenna interfaces, and the two private network LTE test antenna interfaces are 90 mm apart.

[0015] In combination with the first aspect, in some implementations, the private network LTE test antenna is an omnidirectional antenna or a directional antenna.

[0016] In combination with the first aspect, in some implementations, the remote positioning module is used to receive GPS signals and operator base station signals.

[0017] The second aspect of an embodiment of the present invention proposes an LTE network air interface signaling and network status monitoring system, which includes: a data acquisition computer, a display, an air interface monitoring module, a location information module, a power supply module and a remote positioning module; the LTE network air interface signaling and network status monitoring system is used to execute the method described in any one of the first aspects.

[0018] Optionally, the data acquisition computer is the core of the overall system, in which the data acquisition software is running. The air interface monitoring module has the communication function of the private network LTE terminal, and the data acquisition computer controls it through the serial port to enable it to perform corresponding test services, such as FTP service, ping service, etc.

[0019] Optionally, the air interface monitoring module communicates with the private network LTE base station via an antenna, calculates the air interface status data of the private network LTE, and transmits the collected data to a "data acquisition computer" via a serial port.

[0020] Optionally, the location information acquisition module includes a GPS module and a gyroscope. Thus, when the location information acquisition module can normally receive GPS signals, it can directly acquire the longitude and latitude information provided by the GPS and transmit it to the "data acquisition computer".

[0021] Optionally, the gyroscope is automatically corrected according to the GPS information. When entering the tunnel, the processor in the module calculates the state change of the gyroscope and combines the speed, driving direction, altitude, longitude and latitude information before the GPS signal is lost to calculate the longitude and latitude information in the tunnel, and transmits it to the "data acquisition computer" through the serial port.

[0022] Optionally, the "data acquisition computer" merges the private network LTE air interface status data and location information to record the status information of the private network LTE wireless signal at a certain location, providing a basis for network evaluation or problem analysis.

[0023] Optionally, the LTE network air interface signaling and network status monitoring system also includes a private network LTE test antenna interface.

[0024] Optionally, the private network LTE test antenna interface uses the N-KF interface. When testing at fixed points along the track, the matching fiberglass full-line antenna is used. When testing on the vehicle, the roof antenna is connected through a feeder to measure the network status received by the private network LTE vehicle-mounted station.

[0025] Optionally, there are two private network LTE test antenna interfaces, and the two private network LTE test antenna interfaces are 90 mm apart. Figure 2 , Figure 2The schematic diagram of the external interface of the LTE network air interface signaling and network status monitoring system provided by the embodiment of the present application is shown. By setting two private network LTE test antenna interfaces 90mm apart, it can be ensured that there is a certain difference in the reception of the two antennas, which can stimulate the MIMO mode of the network.

[0026] In addition, a nano-SIM card is used in the embodiment of the present application and is inserted into the SIM card slot in the above figure. The power display screen displays the remaining power in real time, and the user can estimate how long the device can last based on the remaining power. The GPS antenna interface uses an SMA-F interface and an external GPS ceramic antenna. The RF interfaces of the present invention all use threaded connections to ensure that the antenna connection is stable and reliable. The present invention also reserves 4 USB interfaces for connecting a mouse, a U disk, etc. The network is connected via the Ethernet port when the system is upgraded, and it does not need to be used during normal testing.

[0027] Furthermore, the private network LTE test antenna provided in the embodiment of the present application may be an omnidirectional antenna or a directional antenna.

[0028] Specifically, during the test, an omnidirectional antenna is sometimes needed, and a directional antenna is sometimes needed. The test needs to be interrupted when the antenna is replaced, and the placement of the directional antenna will also affect the test results. The present invention uses the device's own structure to achieve the conversion between the omnidirectional antenna and the directional antenna. The conversion process does not require interruption of the test, and the antenna posture remains stable. By comparing the carrier-to-interference ratio of the omnidirectional antenna state and the directional antenna state, the direction of the interference source can be located.

[0029] Furthermore, the remote positioning module in the LTE network air interface signaling and network status monitoring system is used to receive GPS signals and operator base station signals. Specifically, GPS can accurately report location information in open-air scenes, but private network LTE is often used in scenes such as subways and railways. These scenes have many tunnels, and GPS cannot report location information in tunnels. The present invention adds a gyroscope on the basis of GPS, and uses the location information reported by GPS in areas with GPS signals. At the same time, the "microprocessor" calibrates the gyroscope state and enters places without GPS signals (such as tunnels). The "microprocessor" measures the motion variables of the gyroscope, combines the position when the GPS signal is lost, calculates the location information and reports it to the "collection computer" to realize the collection of location information in the tunnel, and combines the collection results of the LTE air interface status to form a complete data file, which is convenient for subsequent problem analysis and positioning.

[0030] Optionally, the remote positioning module in the embodiment of the present application can also add a "signal window" specifically on the metal chassis. The "signal window" is 3D printed with organic materials to ensure that the positioning module can receive GPS signals and operator base station signals. When the device is placed outdoors, the positioning module can accurately locate it through GPS signals. When the device is placed indoors, the positioning module locates it through the delay information of the surrounding operator base stations. Users can query the device location information through the mobile phone APP. Even if the device is turned off, the positioning module can still work continuously for more than a week, which is very convenient for retrieving the device after it is lost.

[0031] A third aspect of an embodiment of the present invention provides an electronic device, the electronic device comprising:

[0032] At least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the method proposed in the first aspect of the embodiment of the present invention.

[0033] A fourth aspect of an embodiment of the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the method provided in the first aspect of the embodiment of the present invention.

[0034] In summary, the above method and system have the following technical effects:

Innovation is made in the operation method to simplify the operation steps. The user only needs to turn on the power, the device automatically enters the test mode, and records the test results in a fixed folder. The data collected during the test process include field strength, carrier-to-interference ratio, network transmission mode, RANK value, cell ID, neighboring area information, longitude and latitude, etc., and the collection cycle is 0.2 seconds / time. The simple operation method greatly reduces the technical threshold for users and is more suitable for private network LTE maintenance personnel.

Thus, when the location information acquisition module normally receives GPS signals, it can directly acquire the longitude and latitude information provided by the GPS and transmit it to the "data acquisition computer".

[0050] Optionally, in step S103: after the position information acquisition module acquires the longitude and latitude position information and transmits it to the data acquisition computer, step S1031 may also be included: the gyroscope is automatically corrected according to the GPS information. When entering the tunnel, the processor in the module calculates the state change of the gyroscope and combines the speed, driving direction, altitude, longitude and latitude information before the GPS signal is lost to calculate the longitude and latitude information in the tunnel and transmit it to the data acquisition computer.

[0051] Specifically, the gyroscope is automatically corrected according to the GPS information. When entering the tunnel, the processor in the module calculates the state changes of the gyroscope and combines the speed, driving direction, altitude, longitude and latitude information before the GPS signal is lost to calculate the longitude and latitude information in the tunnel, and transmits it to the "data acquisition computer" through the serial port.

[0052] Step S104: The data collection computer combines the private network LTE air interface status data and the latitude and longitude location information.

[0054] Optionally, the LTE network air interface signaling and network status monitoring system further includes a private network LTE test antenna interface. Thus, the LTE network air interface signaling and network status monitoring method may further include step S105.

[0055] Step S105: The private network LTE test antenna interface adopts the N-KF interface. The matching fiberglass full-line antenna is used for fixed-point testing along the track. The roof antenna is connected through a feeder during on-vehicle testing to measure the network status received by the private network LTE vehicle-mounted station.

Figure 2 , Figure 2 The schematic diagram of the LTE network air interface signaling and network status monitoring system provided by the embodiment of the present application is shown. By setting two private network LTE test antenna interfaces 90mm apart, it can be ensured that there is a certain difference in the reception of the two antennas, which can stimulate the MIMO mode of the network.

The conversion process does not require interruption of the test, and the antenna posture remains stable. By comparing the carrier-to-interference ratio of the omnidirectional antenna state and the directional antenna state, the direction of the interference source can be located. Among them, you can refer to Figure 3 as well as Figure 4 , Figure 3 as well as Figure 4 A schematic diagram of a private network LTE test antenna provided in an embodiment of the present application is shown.

For example, please refer to Figure 5 , Figure 5 A schematic diagram of a signal window provided in an embodiment of the present application is shown.

[0063] The following is an explanation of the specific implementation steps:

[0064] First, the computer starts the win10 operating system after booting up. Then, the Win10 operating system detects the "air interface monitoring module" and the location information module, automatically loads the driver for them, and forms a virtual serial port. Therefore, in the WIN10 operating system, the "data acquisition software" is set to the automatic startup mode, and WIN10 loads the hardware driver and starts the data acquisition software at the same time. Furthermore, the data acquisition software has built-in engineering templates, which include the interface information of the "air interface monitoring module" and the "location information module", the hardware type, the test task, the test map, etc. Therefore, after the data acquisition software is started, the engineering module is automatically loaded, thereby realizing the functions of hardware connection, issuing test tasks, and data saving. The user does not need to intervene in the whole process, and the entire loading and testing process is displayed on the screen. If there are abnormal situations such as freezing or power failure during the test process, the data before the abnormal situation can still be saved normally.

[0065] The present invention is an instrument type device. On site, you only need to connect the antenna and turn on the power. The device automatically enters the test and data collection state. The operation interface has an interrupt collection button. After the interruption of the collection state, data analysis is performed through shortcut keys.

The present invention adds a gyroscope on the basis of GPS, and uses the location information reported by GPS in areas with GPS signals. At the same time, the "microprocessor" calibrates the gyroscope state and enters places without GPS signals (such as tunnels). The "microprocessor" measures the motion variables of the gyroscope, combines the position when the GPS signal is lost, calculates the location information and reports it to the "collection computer" to realize the collection of location information in the tunnel, and combines the collection results of the LTE air interface status to form a complete data file, which is convenient for subsequent problem analysis and positioning.

[0082] Optionally, the remote positioning module in the embodiment of the present application can also add a "signal window" specifically on the metal chassis. The "signal window" is 3D printed with organic materials to ensure that the positioning module can receive GPS signals and operator base station signals. When the device is placed outdoors, the positioning module can accurately locate it through GPS signals. When the device is placed indoors, the positioning module locates it through the delay information of the surrounding operator base stations. Users can query the device location information through the mobile phone APP. Even if the device is turned off, the positioning module can still work continuously for more than a week, which is very convenient for retrieving the device after it is lost.
