Description
Technical Field
The invention relates to the field of communication, in particular to an anti-theft method, an anti-theft system, anti-theft equipment and a storage medium for an integrated small base station.
Background
In the construction of a communication network, a base station that performs a radio signal transmitting/receiving function is of no importance. In practice, there are four types of base stations, which are macro base stations, micro base stations, pico base stations and femto base stations, respectively, and correspond to different single carrier transmitting powers and communication coverage radii. The outdoor signal tower is of course the macro base station. The micro base station, the pico base station and the femto base station are small base stations. Of course, since it is 5G, it is a 5G small cell.
The macro base station has the advantages of high transmitting power, wide coverage range, more supportable carrier frequency and user number and larger capacity. However, the macro base station needs to be provided with a separate machine room and an iron tower, so that the volume and the occupied area are not small, and the defects of difficult installation, poor flexibility and the like exist. Therefore, the method is generally applied to outdoor wide area. The small base station can only support one carrier frequency, and can provide smaller capacity, so that the small base station is much smaller than the macro base station in aspects of appearance form, transmitting power, coverage area and the like, and has the characteristics of higher cost performance, easiness in deployment and the like. So that it is mainly applied to indoor scenes as well. Compared with a macro base station, the small base station can deeply penetrate into a room to perform fixed-point deep coverage in weak signals and blind areas. In addition, in some hot spot areas with dense people flow or large data traffic transmission requirements, the small base station can also help the macro base station to share traffic load, so that the system capacity is improved. Thus, the pain points such as poor penetrability, difficult site selection and the like of the 5G macro base station can be effectively solved.
At present, the integrated small base station may be deployed in public places such as factories, small offices, district parking lots, small business spaces and the like, and the integrated small base station is convenient to install, plug and play and has a theft risk. The traditional base station anti-theft method comprises the steps of adding video monitoring, power environment monitoring, access control management, security alarm, linkage and the like, and a physical device is needed to be added for implementation. For the integrated small base station, the deployment cost is increased, and the installation convenience is reduced.
In view of the above, the present invention provides an anti-theft method, system, device and storage medium for an integrated small cell.

Fig. 1 is a flow chart of an anti-theft method of an integrated small cell of the present invention. As shown in fig. 1, the invention relates to the field of network configuration, and discloses an anti-theft method of an integrated small base station, which comprises the following steps:
S110, the small base station monitors and analyzes the synchronous signals of surrounding neighbor stations, and acquires a real-time neighbor station physical cell identification code set to report to a network management server.
S120, the network management server compares the physical cell identification code set of the real-time neighbor station with the corresponding preset cell identification code set to judge whether the two sets are overlapped. And
And S130, when the preset overlapping condition is not met, sending a deactivation instruction to the small base station, and enabling the small base station to be offline.
The anti-theft method of the integrated small base station can reduce the risk of losing the small base station, does not need to disassemble and assemble a physical anti-theft device, and does not increase the cost. Meanwhile, the installation position of the integrated small base station is more convenient for a user to manually move, and the flexibility of small base station deployment is improved.
According to the invention, a physical anti-theft device is not required to be added, the position information is automatically reported to the small base station network manager through the integrated small base station, once the network manager discovers that the position information of the small base station is changed, a configuration command is issued to deactivate a cell, and the small base station cannot work after being stolen, so that the loss probability is reduced. The traditional base station anti-theft method adopts physical devices, and is inconvenient if the mobile small base station needs to remove the devices and reinstall the devices. The invention controls whether the small base station is allowed to work or not through the network management or the local Web, thereby facilitating the movement of the small base station by the client.
Fig. 2 is a flowchart of step S110 in an embodiment of the anti-theft method of the integrated small cell of the present invention. Fig. 3 is a flowchart of step S120 in an embodiment of the anti-theft method of the integrated small cell of the present invention. Fig. 4 is a flowchart of step S130 in an embodiment of the anti-theft method of the integrated small cell of the present invention. As shown in fig. 2 to 4, in the embodiment of fig. 1, steps S110, S120, S130, S140, S150 are replaced with steps S111, S112, S113, steps S120 are replaced with steps S121, S122, S123, S124, steps S130 are replaced with steps S131, S132, and each step is described below:
S111, after the small base station is started, the Primary Synchronization Signal (PSS) and the Secondary Synchronization Signal (SSS) of surrounding neighbor stations are intercepted and analyzed.
S112, the physical cell identification code of each adjacent station is obtained according to the primary synchronization signal and the secondary synchronization signal. In LTE networks, pci=pss+3 sss. PSS (Primary Synchronization Signal) primary synchronization signals occupy 6 RBs, namely 72sc, of the system bandwidth in the frequency domain, and indicate ID PHYSICAL-layer id in one physical cell group: 0,1,2 (3). PSS values of 0..2 (3 different PSS sequences in practice) SSS values of 0..167 (168 different SSS sequences in practice) PCI can be obtained ranging from 0..503 using the above formula, so there are 504 PCIs in the physical layer. Wherein, the PSS is collectively referred to as Primary Synchronization Signal, namely, a primary synchronization signal, and is used for transmitting an intra-group ID, namely, N (2) _ID value. The SSS is collectively referred to as Secondary Synchronization Signal, a secondary synchronization signal, for transmitting the group ID, N (1) _ID value. RSRP (REFERENCE SIGNAL RECEIVED Power ), -44 to-140 dBm, the larger the value is, the better. RSSI (RECEIVED SIGNAL STRENGTHEN Indicator), range of values: -110-90. RSRQ (REFERENCE SIGNAL RECEIVED Quality ), range of values: -3 to-19.5, the larger the value, the better rsrq=n RSRP/RSSI. SINR (Signal to Interference & Noise Ratio) is the Ratio of the useful signal power to the sum of the interference and Noise power, directly reflecting the quality of the received signal. SNR is an abbreviation of signal to noise ratio, signal-to-noise ratio, which refers to the ratio between the level of a useful signal measured under specified conditions and the level of electromagnetic noise. The ratio of the amplitude of the useful signal at any point to the amplitude of the noise signal at the same point is expressed in decibels (dB). The peak value is associated with impulse noise and the effective value is associated with random noise.
S113, establishing a real-time neighbor station physical cell identification code set and reporting the set to a network management server.
S121, obtaining a union set of the network management server based on the real-time neighbor station physical cell identification code set and the corresponding preset cell identification code set. The preset cell identification code set is a real-time neighbor station physical cell identification code set uploaded when the small base station is started for the first time or started for the last time; or the preset cell identification code set is a set of all adjacent station physical cell identification codes with occurrence frequencies exceeding a preset threshold value in all adjacent station physical cell identification code sets uploaded by the small base station historically.
S122, acquiring an intersection set of the network management server based on the real-time neighbor station physical cell identification code set and the corresponding preset cell identification code set.
S123, the obtained cell identification codes in the intersection account for the percentage of all the cell identification codes in the union.
And S124, when the percentage is smaller than a preset threshold value, the preset overlapping condition is not met. For example: the preset cell identification code sets are { A1, A2, A3, A4 and A5}, the network management server is based on the fact that the real-time neighbor station physical cell identification code sets are { A1, A2, A3 and A4}, the intersection of the two sets is the union { A1, A2, A3, A4 and A5}, the percentage of the cell identification codes in the intersection to the cell identification codes in the union is 80%, if the preset threshold value is 75%, the actual measurement result is greater than the preset threshold value by 75%, and the condition that the preset overlapping condition is met is considered to be met, so that no movement occurs. If the percentage of the actual measurement result is 60% and is smaller than the preset threshold value, the preset overlapping condition is considered not to be met, and the small base station is considered to be moved.
In a preferred embodiment, in order to avoid the situation that other surrounding base stations are mistakenly considered to be moved (the neighboring base station sets where the surrounding base stations can receive the synchronization signal are all changed) due to the temporary outage or failure of the respective small base stations, when the network management server does not include all the cell identifiers in the preset cell identifier set based on the physical cell identifier set of the real-time neighboring base stations, the network management server trains whether the other surrounding small base stations of the non-included small base stations can obtain the cell identifier of the non-included small base station, and if not, temporarily deletes the cell identifier of the non-included small base station from the preset cell identifier set, thereby avoiding the interference to the identification accuracy in the case of temporary outage.
S131, when the small base station does not meet the preset overlapping condition, the network management server sends a deactivation instruction to the small base station.
S132, the small base station executes the offline operation according to the received deactivation instruction.
