FIG. 1 is a schematic structural diagram of a terminal management and control system provided by an embodiment of the present application. As shown in FIG. 1 , the terminal management and control system includes a management and control platform 101 , a management and control base station 102 and an antenna 103 . Wherein, one end of the management and control base station 102 is connected to the management and control platform 101 , and the other end of the management and control base station 102 is connected to the antenna 103 . The management and control platform 101 can be connected to the management and control base station 102 through a network cable, and the management and control base station 102 can be connected to the antenna 103 through a feeder, and the antenna 103 can be a MIMO (multiple-in multiple out, multiple-input-multiple-out) antenna or an antenna composed of multiple MIMO antennas An array, the antenna 103 is usually deployed in a "low-power, multi-antenna" deployment method.

The terminal management and control method mentioned in this application is illustrated as follows with reference to the accompanying drawings. FIG. 2 is a schematic flowchart of a terminal management and control method provided in an embodiment of the present application, and the method is applied to the terminal management and control device in the above-mentioned terminal management and control system. As shown in Figure 2, the method may include:

S201. Detect configuration parameters of public network base stations in the control area.

Specifically, after the above-mentioned terminal management and control system is deployed, in the quasi-working state, the management and control base station can detect the electromagnetic environment in the control area in real time through the antenna connected to it, and analyze the electromagnetic environment information to obtain the corresponding electromagnetic environment information. The configuration parameters of the public network base station. At the same time, the management and control base station sends the analyzed configuration parameters of the public network base station to the management and control platform connected to it, and the management and control platform can store and display the acquired configuration parameters of the public network base station. Wherein, the configuration parameters of the public network base station may include at least one of the following information: Mobile Network Code (Mobile NetworkCode, MNC), Mobile Country Code (Mobile Country Code, MCC), Physical Cell Identifier (Physical CellIdentifier, PCI), synchronization signal Receiving strength value (Synchronization Signal-Reference Signal Receiving Power, SS-RSRP), synchronization signal receiving quality value (Synchronization Signal-Reference Signal Receiving Quality, SS-RSRQ), center frequency band, downlink operating frequency point, tracking area (TrackingArea, TA), Tracking Area Code (TrackingArea Code, TAC) and other parameters.

S202. According to the configuration parameters of the public network base station, set the working parameters of the management and control base station, so that the network signal of the management and control base station meets a preset network switching condition.

Specifically, the management and control platform can set the working parameters of the management and control base station according to preset network switching conditions after obtaining the specific information about the configuration parameters of the public network base station. The working parameters of the control base station can be set in the following two ways. One is the automatic way. After analyzing the specific information of the configuration parameters of the public network base station, it can use power self-adaptive according to the preset network switching conditions. The control method and the boundary signal control method set the working parameters of the management and control base station. The power adaptive control method and the boundary signal control flexible method are respectively a power detection and adaptive control algorithm on the management and control platform, which can be adaptively adjusted The control base station network signal transmission power is used to improve the accuracy of the control base station network signal and reduce the impact on outside the control area.

For example, the innermost outer wall of the prison is a control area, because the control area has a boundary. In principle, the network signal of the control base station cannot exceed the outermost wall, but the network signal is a wireless signal, and the wireless signal is not Boundary, its propagation characteristics determine that it is impossible to achieve a wall separation, so the power adaptive control method and the boundary signal control flexible method can improve the accuracy of controlling the network signal of the base station and reduce the interference of wireless signals outside the control area . In general, it can be ensured that the buffer distance of the physical boundary controlling the network signal of the base station is less than 10 meters.

The other is the manual method. The staff can manually set the working parameters of the management and control base station according to the specific information of the configuration parameters of the public network base station obtained after analysis and the preset network switching conditions. The power level control can be set on the interface, and the working parameters of the control base station can be set in a more refined manner, so that the working parameter setting of the control base station is more in line with the preset network switching conditions.

The preset network switching condition may be that the network signal strength (Srxle) and quality value (Squal) of the control base station are greater than the network signal strength (Srxle) and quality value (Squal) of the public network base station respectively. If the network signal of the management and control base station meets the preset network switching condition, the following condition 1 and the following condition 2 must be met. Among them, the specific content of condition 1 is:

S standard: Srxle>0, and Squal>0

S standard calculation formula:

Srxle=Qrxlevmeas-(Qrxlevmin+Qrxlevminoffset)-Pcompensation-Qoffsettemp;

Squal=Qqualmeas-(Qqualmin+Qqualminoffset)-Qoffsettemp;

in:

Srxle: indicates that the terminal network selects the received signal strength value;

Qrxlevmeas: indicates the synchronization signal received strength value (SS-RSRP) actually measured by the terminal;

Qrxlevmin: indicates the minimum received signal strength value required by the terminal to access the network (equivalent to the threshold for network access);

Qrxlevminoffset: indicates the terminal received signal strength compensation value;

Pcompensation: indicates the parameter value related to the terminal uplink power compensation;

Qoffsettemp: Indicates the compensation value of the network (information carried in the downlink);

Squal: Indicates that the terminal network selects the received signal quality value;

Qqualmeas: indicates the synchronization signal reception quality value (SS-RSRQ) actually measured by the terminal;

Qqualmin: indicates the minimum received signal quality value required by the terminal to access the network (equivalent to the threshold for network access);

Qqualminoffset: Indicates the terminal received signal quality compensation value.

The above condition 1 can also be referred to as conforming to the network selection S standard. Only when the Srxle parameter in the S standard is greater than 0 and the Squal parameter is greater than 0, can the terminal be connected to the network signal including the above parameters. That is to say, when the network signal strength value received by a terminal (such as a mobile phone) is greater than a certain threshold, and the network signal quality value is also greater than a certain threshold, the terminal may access the network. Wherein, one of the above-mentioned threshold values is all 0.

The terminal can analyze the specific information of all the parameters in the above condition 1 from the network signal of the management and control base station. On the basis of setting the working parameters of the management and control base station to meet the above condition 1, in order for the terminal to choose the management and control base station under any circumstances If the network signal is connected, then the working parameter setting of the control base station must also meet the condition 2, which essentially limits the parameters in the condition 1. Among them, the specific content of the condition 2 is:

The synchronization signal received strength value (SS-RSRP) of the control base station is greater than the synchronization signal received strength value (SS-RSRP) of the public network base station, and the difference between the two is within a preset signal strength interval, and the preset signal strength interval can be Set to (10-15)dBm according to experience. Wherein, the preset signal strength interval may be set according to actual conditions, which is not limited in this application. The minimum received signal strength value (Qrxlevmin) of the controlled base station is smaller than the minimum received signal strength value (Qrxlevmin) of the public network base station. Generally, the smaller the minimum received signal strength value (Qrxlevmin) of the controlled base station, it means that it can be The terminal is easier to choose. For example, if the minimum received signal strength value (Qrxlevmin) of the public network base station is (-115) dBm, then the minimum received signal strength value (Qrxlevmin) of the control base station only needs to be less than (-115) dBm, for example It can be set to (-120) dBm, and the specific value is not limited by this application; the Qrxlevminoffset parameter, Pcompensation parameter, and Qoffsettemp parameter of the control base station are respectively greater than the Qrxlevminoffset parameter, Pcompensation parameter, and Qoffsettemp parameter of the public network base station. Application does not limit it.

The synchronization signal reception quality value (SS-RSRQ) of the control base station is greater than the synchronization signal reception quality value (SS-RSRQ) of the public network base station, and the difference between the two is within a preset signal quality interval, and the preset signal quality interval can be Set to (1-5)dBm based on experience. Wherein, the preset signal quality interval may be set according to actual conditions, which is not limited in this application. The minimum received signal quality value (Qqualmin) of the controlled base station is smaller than the minimum received signal quality value (Qqualmin) of the public network base station. Generally, the smaller the minimum received signal quality value (Qqualmin) of the controlled base station, it means that it can be The terminal is easier to choose. For example, if the minimum received signal quality value (Qqualmin) of the public network base station is (-8) dBm, then the minimum received signal quality value (Qqualmin) of the control base station only needs to be less than (-8) dBm, for example It can be set to (-10)dBm, and this application does not limit the specific value; the Qqualminoffset parameter and Qoffsettemp parameter of the control base station are respectively greater than the Qqualminoffset parameter and Qoffsettemp parameter of the public network base station, and the specific value is not limited by this application.

Further, the individual working parameters of the control base station can also be set separately, for example, the working frequency band of the control base station can be set to be the same as the detected working frequency band of the public network base station; the downlink working frequency band of the control base station can be set The frequency point and the physical cell ID are respectively set to be the same as the downlink working frequency point and the physical cell ID of the public network base station. Under normal circumstances, the frequency point with the second highest power in the neighborhood of the public network base station will be used as the downlink operating frequency point of the control base station, so as to avoid confrontation with the network signal of the public network base station and reduce interference to the outside world.

According to the content in the above condition 2, combined with the S standard calculation formula in the above condition 1 and the above-mentioned requirements for setting individual working parameters of the control base station, it can be obtained that the terminal receives the network signal strength value of the control base station (Srxle ) and quality value (Squal) are respectively greater than the strength value (Srxle) and quality value (Squal) of the terminal receiving the network signal of the public network base station, that is to say, the network signal of the control base station meets the preset network switching condition.

S203. Send a handover broadcast signal according to the working parameters of the management and control base station.

Wherein, the switching broadcast signal is used to make the terminals in the management and control area switch from the public network base station to the management and control base station when detecting that the network switching condition is met from the switching broadcast signal.

Specifically, after the network signal of the management and control base station satisfies the preset network switching condition, the switching broadcast signal may be sent to the terminals in the management and control area through the downlink, wherein the switching broadcast signal may include the network switching signal of the management and control base station. The specific working parameters of the network signal, such as the specific parameters in the above condition 1. The terminal can search for any network signal that meets the above condition 1, such as the network signal of the management and control base station and the network signal of the public network base station. Since the strength value and quality value of the network signal of the control base station are respectively better than the network signal strength value and quality value of the public network base station, that is to say, the network signal of the control base station is the best network in the control area, Therefore, the terminal can switch from the public network base station to the management and control base station. Wherein, the specific form of the terminal can be a mobile phone, a tablet computer, a wearable device that can be connected to the Internet, and other Internet of Things devices.

To sum up, in the terminal management and control method provided by this application, the configuration parameters of the public network base stations in the management and control area are detected; according to the configuration parameters of the public network base stations, the working parameters of the management and control base stations are set, so that the network of the management and control base stations The signal meets the preset network switching conditions; according to the working parameters of the management and control base station, the switching broadcast signal is issued; the switching broadcast signal is used to make the terminal in the control area detect from the switching broadcast signal that the network switching condition is met , switching from the public network base station to the management and control base station. Using the terminal management and control method provided by the embodiment of the present application, the operating parameters of the management and control base station are set through the configuration parameters of the public network base station, so that the network signal of the management and control base station meets the preset network switching conditions, so that the terminal can preferentially choose to connect to the Controlling the base station, and then switching from the public network base station to the management and control base station, this method improves the control accuracy of the terminal.

Fig. 3 is a schematic flowchart of another terminal management and control method provided in the embodiment of the present application. As shown in Fig. 3, the method may also include:

S301. Send a network unavailable signaling according to the working parameters of the management and control base station.

S302. Send a state transition signaling.

Specifically, regardless of whether the terminal has just entered the control area or has been in the control area, as long as the terminal is turned on, it can search for all network signals in the control area. For example, when the terminal is connected to the pipe network base station, it can also search for surrounding network signals in real time. When the terminal discovers the network signal of the control base station on other frequency points that at least meets the condition 1 and condition 2, it can measure the network signal and send the measurement report obtained after the measurement to the public network base station. Wherein, the content of the measurement report includes: a better network signal is found. Since the terminal management and control system is an independent system, and the public network base station is not configured as a neighbor cell, the public network base station does not find any information about the network signal of the management and control base station in the neighbor cell list. Furthermore, after a period of time, the terminal will never receive the handover command issued by the public network base station through the reconfiguration message, so the terminal still has network signals with the management and control base station.

After the terminal switches to the management and control base station, the management and control platform can issue the network unavailable signaling to the terminal through the management and control base station through the downlink, and the network unavailable signaling can be used to prohibit the communication service of the terminal . For example, when the terminal is a mobile phone, the network unavailable signaling can make the user unable to make a call, send and receive short messages and surf the Internet through the mobile phone.

After the network unavailable signaling is issued, the management and control platform may also issue the state transition signaling to the terminal through the downlink through the management and control base station, and the state transition signaling may be used to instruct the terminal to switch from the connected state to idle state or deactivated state. At the same time, a camping signaling will also be issued, and the camping signaling can be used to instruct the terminal to camp on the management and control base station, so that the terminal can always camp on the network generated by the management and control base station.

Optionally, the method may further include: issuing a reselection measurement instruction, where the reselection measurement instruction includes: a preset reselection trigger time, and the reselection measurement instruction is used to instruct the terminal to start Parameter measurement for network reselection, and reselect to access the management and control base station when the measured parameters meet the preset network reselection conditions.

Specifically, when a terminal in an idle state or deactivated state passes through or stays in the control area, the terminal will also measure the network in the same frequency neighborhood in real time, so as to reselect to a better network to obtain services, which is A function inherent to the terminal. Then, the present application can enable the terminal to reselect to access the management and control base station in the following manner.

The management and control platform sends the parameters in the above condition 1 to the terminal in real time, and can obtain the Srxle parameter or Squal parameter of the network signal of the management and control base station, and the terminal can also measure the corresponding co-frequency neighbors of the management and control base station and the public network base station in real time The network threshold of the domain, such as SintrasearchP (threshold for starting same-frequency signal strength measurement), SintrasearchQ (starting threshold for same-frequency signal quality measurement). When Srxlev<SintrasearchP or Squal<SintrasearchQ, the terminal starts reselection measurement. In order to quickly start the reselection measurement of the management and control base station, in general, in the above stage of setting the working parameters of the management and control base station according to the configuration parameters of the public network base station, you can set the SintrasearchP or SintrasearchQ of the management and control network to be greater than The corresponding parameter value of the public network base station.

In order for the terminal to reselect to access the control base station, the network reselection condition can be set in advance, and the network reselection condition can be: the network parameter (Rs) issued by the public network base station is less than the network parameter (Rs) issued by the control base station Network parameters (Rn). If the parameters measured by the terminal satisfy the network reselection condition, the following condition 3 must be met. Among them, the specific content of condition 3 is:

R standard: Rs<Rn

R standard calculation formula:

Rs=Qmeas,s+QHyst-Qoffsettemp;

Rn=Qmeas, n-Qoffset-Qoffsettemp;

Rs: R value of the public network;

Qmeas,s: the SS-RSRP value of the public network actually measured by the terminal;

QHyst: public network offset value, protection amount;

Qoffsettemp: public network compensation value, which will be brought down in the system information;

Rn: the R value of the control network;

Qmeas,n: SS-RSRP value of the management and control network actually measured by the terminal;

Qoffset: the offset value and protection amount of the control network;

Qoffsettemp: The network compensation value of the control network, which will be brought down in the system information.

The above condition 3 can also be called the network reselection R standard. In order to make the Rs parameter smaller than the Rn parameter, the following setting requirements must also be met when setting the working parameters of the control base station. limited. Specifically, the parameter (Qmeas, n) is greater than the parameter (Qmeas, s), which is similar to the parameter limit of (SS-RSRP) mentioned in condition 2 above, and will not be described in detail here; the parameter (Qoffset) is smaller than (QHyst) Parameter, how much less than this application does not limit it, generally, the (Qoffset) parameter can be set to a negative value; (Qoffsettemp) parameter is not less than (Qoffsettemp) parameter, specifically not less than how much this application does not limit it, generally In some cases, both can be set to the same value.

According to the above manner, the network parameter (Rs) delivered by the public network base station can be made smaller than the network parameter (Rn) delivered by the management and control base station. Then, as long as the terminal starts the parameter measurement of network reselection within the preset reselection trigger time, it can reconnect to the management and control base station. Wherein, the preset reselection trigger time can be set as a dynamic parameter, for example, the value range can be (0-30) seconds. It should be noted that, how much is the preset reselection trigger time range? Application does not limit it. The preset reselection trigger time can be automatically adjusted according to the different states of the terminal reselection, for example, when the terminal does not reselect to the management base station, the preset reselection trigger time can be set to a value range The minimum value within; when reselecting to the management and control base station, the preset reselection trigger time can be set to the maximum value within the value range. The smaller the preset reselection trigger time, the faster the terminal reselects to the management and control base station, and the shorter the time; the larger the preset reselection trigger time, the longer the terminal stays after reselecting to the management and control base station longer.

Fig. 4 is a schematic flowchart of another terminal management and control method provided in the embodiment of the present application. As shown in Fig. 4, the method may also include:

S401. After the terminal reselects to access the management and control base station, it receives a tracking area update request.

S402. Obtain the network identifier of the terminal from the tracking area update request.

Specifically, when setting the working parameters of the management and control base station above, the tracking area code can be set to be automatically updated according to the preset time. The preset time can be 30 minutes. The tracking area code is more specific It is updated once in a long time and needs to be set according to the actual situation, which is not limited in this application. When the tracking area code is updated, the terminal will send a Tracking Area Update (TAU) request to the management and control platform. After receiving the tracking area update request, the management and control platform can obtain the network identifier of the terminal. The identifier can be GUTI (Globally Unique Temporary UE Identity, Globally Unique Temporary UE Identity) or SUCI (Subscription Concealed Identifier, hidden user identifier) information, which represents a dynamic identifier assigned to the terminal by the public network base station, unique The network information of the terminal under the public network base station is identified.

S403. Send an identity response signaling to the terminal according to the network identifier of the terminal.

S404. Receive a reply message reported by the terminal, where the reply message includes: identity information of the terminal.

Specifically, according to the above GUTI/SUCI information, the management and control platform can issue an identity response signaling to the terminal in plain text. After receiving the identity response signaling, the terminal may reply the identity response message by using direct read integrity protection, and send the reply message to the control platform.

S405. According to the identity information of the terminal, send a signaling of rejecting the tracking area update request to the terminal.

Specifically, the reply message includes the identity information of the terminal, such as SUPI (SubscriptionPermanent Identifier, subscription permanent identifier), IMEI (International Mobile Equipment Identity, international mobile equipment identity code) and other information. Among them, the SUPI is used to represent the unique permanent identity of the user in the 5G network, similar to the IMSI in the LTE network (4G). After obtaining information such as SUPI, IMEI, etc., the management and control platform can issue a signaling rejecting the tracking area update request to the terminal. After the terminal receives the signaling rejecting the tracking area updating request, the terminal abandons the TAU process, while indicating that the TAU process cannot be completed.

Fig. 5 is a schematic flowchart of another terminal management and control method provided in the embodiment of the present application. As shown in Fig. 5, the method may also include:

S501. Determine whether the terminal is an illegal terminal according to the identity information of the terminal.

Wherein, the illegal terminal may be an unauthorized terminal in the control area, or a terminal used in violation of regulations. The list of legal terminals can be stored in the database of the management and control platform in advance, and the list of legal terminals includes identification information of multiple legal terminals, and the obtained identification information of terminals can be matched with the list of legal terminals. If the identification information of the terminal is in the list of legal terminals, it is proved that the terminal is a legal terminal, and if the identification information of the terminal is not in the list of legal terminals, it is proved that the terminal is an illegal terminal.

S502. If the terminal is not an illegal terminal, send a release signaling to the terminal.

Specifically, when the terminal is a legal terminal, the management and control platform can issue a release signaling to the terminal, so that the terminal can switch to access the public network base station, thereby performing normal communication. The released terminal information can be represented by a released terminal list and stored in the database in advance, then the management and control platform can no longer send the above-mentioned identity response signaling process to the terminals in the released terminal list. When the terminal sends the above tracking area update request next time, it will be released directly. In this way, not only the security of information in the control area can be guaranteed, but also the legal terminals in the control area can communicate normally.
