Fig. 1 is a schematic structural diagram of a terminal management and control system provided in an embodiment of the present application, and 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. 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 may be connected to the management and control base station 102 through a network cable, the management and control base station 102 may be connected to the antennas 103 through a feeder, the antennas 103 may be MIMO (multiple-in multiple-out) antennas or antenna arrays composed of multiple MIMO antennas, the antennas 103 are generally deployed in a "low power and multiple antennas" deployment manner, for example, the multiple antennas 103 may be deployed at preset positions in a management and control area, where an outlet power of each antenna 103 may be less than or equal to 15dBm, a coverage radius may be less than or equal to 10m, and it should be noted that the present application does not limit the outlet power and a signal coverage radius of the antennas 103. In the case that the size of the regulatory region is known, the number of the antennas 103 required can be obtained according to the signal coverage radius of a single antenna 103. By adopting a deployment mode of 'low power and multiple antennas', network signals of the control base station 102 can be guaranteed to uniformly cover all positions of the control area, no dead angle and no blind area are achieved, and the control precision of the terminal can be improved.
The terminal management and control method mentioned in the present application is exemplified as follows with reference to the accompanying drawings. Fig. 2 is a schematic flowchart of a terminal management and control method according to an embodiment of the present disclosure, where the method is applied to a terminal management and control device in the terminal management and control system. As shown in fig. 2, the method may include:
s201, detecting configuration parameters of public network base stations in a control area.
Specifically, after the terminal management and control system is deployed, in a quasi-working state, the management and control base station may detect an electromagnetic environment in the management and control area in real time through an antenna connected to the management and control base station, and analyze the electromagnetic environment information to obtain configuration parameters of the public network base station corresponding to the electromagnetic environment information. And meanwhile, the management and control base station sends the analyzed configuration parameters of the public network base station to a management and control platform connected with the management and control base station, and the management and control platform can store and display the acquired configuration parameters of the public network base station. The configuration parameter of the public network base station may include at least one of the following information: mobile Network Code (MNC), mobile Country Code (MCC), physical Cell Identifier (PCI), synchronization Signal received strength value (SS-RSRP), synchronization Signal received Quality value (SS-RSRQ), center frequency band, downlink working frequency point, tracking Area (TA), tracking Area Code (TAC), and other parameters.
S202, setting working parameters of the management and control base station according to 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 condition.
Specifically, after acquiring the configuration parameter specific information of the public network base station, the management and control platform may set the working parameters of the management and control base station according to a preset network switching condition. The working parameters of the management and control base station can be set in two ways, one is an automatic way, after the specific configuration parameter information of the public network base station is analyzed, the working parameters of the management and control base station can be set by using a power self-adaptive control method and a boundary signal control method according to preset network switching conditions, the power self-adaptive control method and the boundary signal control flexible method are respectively a power detection and self-adaptive control algorithm on the management and control platform, the network signal transmitting power of the management and control base station can be adjusted in a self-adaptive mode, the network signal precision of the management and control base station is improved, and the influence outside the management and control area is reduced.
For example, the inside of the outermost fence monitored by the station is a control area, because the control area is bounded, the network signal of the control base station cannot exceed the outermost fence in principle, but the network signal is a wireless signal, the wireless signal is unbounded, and its propagation characteristics determine that it is impossible to achieve a wall separation, so by using the power adaptive method and the boundary signal control flexible method, the accuracy of the network signal of the control base station can be improved, and the interference to the wireless signal outside the control area can be reduced. Generally, the physical boundary buffer distance of network signals of the management and control base station can be ensured to be less than 10 meters.
The other mode is a manual mode, a worker can manually set working parameters of the management and control base station according to the specific configuration parameter information of the public network base station obtained after analysis and the preset network switching condition, and the working parameters of the management and control base station can be set more finely due to the fact that the power gear control can be arranged on the interface of the management and control platform setting parameters, so that the working parameter setting of the management and control base station is more in line with the preset network switching condition.
The preset network switching condition may be that the strength value (Srxle) and the quality value (Squal) of the network signal of the management and control base station are respectively greater than the strength value (Srxle) and the quality value (Squal) of the network signal of the public network base station. If the network signal of the management and control base station satisfies the preset network handover condition, the following condition 1 and the following condition 2 must be satisfied. The specific content of the condition 1 is as follows:
and (S) standard: srxle > 0 and Squal > 0
S standard calculation formula:
Srxle＝Qrxlevmeas-(Qrxlevmin+Qrxlevminoffset)-Pcompensation-Qoffsettemp；
Squal＝Qqualmeas-(Qqualmin+Qqualminoffset)-Qoffsettemp；
wherein:
srxle: representing a terminal network selection received signal strength value;
qrxlevmeas: representing a synchronization signal received strength value (SS-RSRP) actually measured by the terminal;
qrxlevmin: a minimum received signal strength value (corresponding to a threshold for network access) indicating a requirement for the terminal to access the network;
qrxlevminooffset: representing a terminal received signal strength compensation value;
pcompenisation: a parameter value representing a value associated with uplink power compensation of the terminal;
qoffset: a compensation value representing the network (information carried in the downlink);
squal: indicating a terminal network selected received signal quality value;
qqualmeas: indicating a synchronization signal reception quality value (SS-RSRQ) actually measured by the terminal;
qqualmin: a minimum received signal quality value (corresponding to a threshold for network access) indicative of a requirement for access of the terminal to the network;
qqualminoffset: representing the terminal received signal quality compensation value.
The condition 1 may also be referred to as meeting the S standard for network selection, and the terminal may connect the network signal including the Srxle parameter in the S standard if the Srxle parameter is greater than 0 and the Squal parameter is greater than 0. That is, the terminal (e.g., handset) may access the network only if the received network signal strength value is greater than a certain threshold and the network signal quality value is also greater than a certain threshold. Wherein, the threshold values are all 0.
The terminal may analyze all the parameter specific information in the condition 1 from the network signal of the management and control base station, and on the basis that the operating parameter of the management and control base station satisfies the condition 1, in order to enable the terminal to preferentially connect with the network signal of the management and control base station under any condition, the operating parameter of the management and control base station must also satisfy a condition 2 when setting the operating parameter of the management and control base station, where the condition 2 substantially defines the parameter in the condition 1. Wherein, the concrete content of the condition 2 is as follows:
the synchronization signal received strength value (SS-RSRP) of the management and control base station is larger than the synchronization signal received strength value (SS-RSRP) of the public network base station, the difference between the two is within a preset signal strength interval, and the preset signal strength interval can be set to be (10-15) dBm according to experience. Wherein, this preset signal intensity interval can set up according to actual conditions, and this application does not prescribe a limit to this. The minimum received signal strength value (Qrxlevmin) of the management and control base station is smaller than the minimum received signal strength value (Qrxlevmin) of the public network base station, and generally, the smaller the minimum received signal strength value (Qrxlevmin) of the management and control base station is, the smaller the minimum received signal strength value (Qrxlevmin) of the management and control base station represents that the minimum received signal strength value (Qrxlevmin) of the public network base station is easier to be selected by the terminal, for example, if the minimum received signal strength value (Qrxlevmin) of the public network base station is (-115) dBm, the minimum received signal strength value (Qrxlevmin) of the management and control base station is only smaller than (-115) dBm, for example, may be set to (-120) dBm, and specifically, how much smaller the minimum received signal strength value (Qrxlevmin) of the management and control base station is not limited by the application; the Qrxlevminoffset parameter, the Pcompenation parameter and the Qoffset parameter of the management and control base station are respectively greater than the Qrxlevminoffset parameter, the Pcompenation parameter and the Qoffset parameter of the public network base station, and are specifically greater than the quantity of the Qoffset parameter, the Pcompenation parameter and the Qoffset parameter, so that the Qoffset parameter is not limited.
The synchronization signal receiving quality value (SS-RSRQ) of the management and control base station is larger than that (SS-RSRQ) of the public network base station, the difference between the two is within a preset signal quality interval, and the preset signal quality interval can be set to be (1-5) dBm according to experience. The preset signal quality interval can be set according to actual conditions, and the preset signal quality interval is not limited by the application. The minimum received signal quality value (Qqualmin) of the policing 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 policing base station is, the easier it is to select the policing base station by the terminal, if the minimum received signal quality value (Qqualmin) of the public network base station is (-8) dBm, the minimum received signal quality value (Qqualmin) of the policing base station is only smaller than (-8) dBm, for example, the minimum received signal quality value (Qqualmin) of the policing base station can be set to be (-10) dBm, and specifically, the minimum received signal quality value (Qqualmin) is not limited by the application; the Qqualminoffset parameter and Qoffset parameter of the management and control base station are respectively greater than the Qqualminoffset parameter and Qoffset parameter of the public network base station, and are specifically greater than the Qqualminoffset parameter and the Qoffset parameter, and the management and control base station is not limited by the method.
Further, individual working parameters of the management and control base station may be set individually, for example, the working frequency band of the management and control base station may be set to be the same as the detected working frequency band of the public network base station; the downlink working frequency point and the physical cell identifier of the management and control base station can be set to be the same as those of the public network base station respectively. Under general conditions, the frequency point with the second highest power in the neighboring area of the public network base station is used as the downlink working frequency point of the management and control base station, so that the positive confrontation with the network signal of the public network base station can be avoided, and the interference to the outside is reduced.
According to the content in the condition 2, in combination with the S standard calculation formula in the condition 1 and the requirement for setting the individual operating parameters of the management and control base station, it can be obtained that the intensity value (Srxle) and the quality value (Squal) of the network signal of the management and control base station received by the terminal are respectively greater than the intensity value (Srxle) and the quality value (Squal) of the network signal of the public network base station received by the terminal, that is, the network signal of the management and control base station satisfies the preset network handover condition.
And S203, issuing a switching broadcast signal according to the working parameters of the management and control base station.
The switching broadcast signal is used for switching the terminal in the regulatory region from the public network base station to the regulatory 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 meets the preset network switching condition, the switching broadcast signal may be issued to the terminal in the management and control area through a downlink, where the switching broadcast signal may include specific operating parameters of the network signal of the management and control base station, such as the specific parameters in condition 1 above. The terminal may search for any network signal that satisfies the 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 the quality value of the network signal of the management and control base station are better than those of the network signal of the public network base station, respectively, that is, the network signal of the management and control base station is the best network in the management and control area, the terminal can be switched from the public network base station to the management and control base station. The specific form of the terminal can be a mobile phone, a tablet personal computer, wearable equipment capable of being networked and other Internet of things equipment.
To sum up, in the terminal management and control method provided by the present application, configuration parameters of public network base stations in a management and control area are detected; setting working parameters of a management and control base station according to the configuration parameters of the public network base station, so that network signals of the management and control base station meet preset network switching conditions; issuing a switching broadcast signal according to the working parameters of the management and control base station; the handover broadcast signal is used for enabling the terminal in the regulatory region to handover from the public network base station to the regulatory base station when detecting that the network handover condition is met from the handover broadcast signal. By adopting the terminal management and control method provided by the embodiment of the application, the working 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 condition, the terminal can be preferentially connected with the management and control base station, and then the public network base station is switched to the management and control base station, and the management and control precision of the terminal is improved.
Fig. 3 is a schematic flowchart of another terminal management and control method provided in the embodiment of the present application, and as shown in fig. 3, the method may further include:
s301, issuing network unavailable signaling according to the working parameters of the management and control base station.
And S302, transmitting the state transition signaling.
Specifically, regardless of whether the terminal just enters the regulation area or is always in the regulation area, as long as the terminal is powered on, all network signals in the regulation area can be searched. For example, when the terminal is connected to the pipe network base station, the terminal may search for a surrounding network signal in real time. When the terminal finds the network signals of the management and control base station on other frequency points at least meeting the conditions 1 and 2, the measurement report obtained after measurement can be sent to the public network base station by measuring the network signals. Wherein the measurement report content comprises: a better network signal is found. And because the terminal management and control system is an independent system and the public network base station does not configure the management and control base station as a neighboring cell, the public network base station does not find any information about the network signal of the management and control base station in a neighboring cell list, and after a period of time, the terminal cannot receive the switching instruction issued by the public network base station through the reconfiguration message, so that the terminal still has the network signal with the management and control base station.
After the terminal is switched to the management and control base station, the management and control platform may issue the network unavailable signaling to the terminal through a downlink by the management and control base station, and the network unavailable signaling may be used to prohibit a communication service of the terminal. For example, when the terminal is a mobile phone, the network unavailable signaling may enable the user to not talk, 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 management and control base station through a downlink, where the state transition signaling may be used to instruct the terminal to switch from a connected state to an idle state or a deactivated state. Meanwhile, a residence signaling is also issued, and the residence signaling may be used to indicate that the terminal resides in the management and control base station, so that the terminal may always reside in the network generated by the management and control base station.
Optionally, the method may further include: issuing a reselection measurement instruction, wherein the reselection measurement instruction comprises: and the reselection measurement instruction is used for indicating the terminal to start parameter measurement of network reselection within the reselection trigger time, and reselecting to access the management and control base station when the measured parameters meet preset network reselection conditions.
Specifically, when a terminal in an idle state or a deactivated state passes through or stays in the control area, the terminal may also measure a network in a same-frequency neighborhood in real time, so as to reselect to a better network to obtain a service, which is an inherent function of the terminal. Then, the present application may enable the terminal to reselect to access the governing base station in the following manner.
The control platform issues the parameters in the condition 1 to the terminal in real time, so as to obtain Srxle parameters or Squal parameters of the network signals of the control base station, and the terminal can also measure network thresholds of the control base station and corresponding co-frequency neighborhoods of the public network base station in real time, such as SintrasearchP (co-frequency signal strength measurement start threshold) and SintrasearchQ (co-frequency signal quality measurement start threshold). When Srxlev < SintrasearchP or Squal < SintrasearchQ, the terminal initiates reselection measurement. In order to quickly start reselection measurement on the management and control base station, in general, in the stage of setting the operating parameters of the management and control base station according to the configuration parameters of the public network base station, sintrasearchP or SintrasearchQ of the management and control network may be set to corresponding parameter values greater than that of the public network base station.
In order to enable the terminal to reselect and access to the management and control base station, the network reselection condition may be set in advance, and the network reselection condition may be: the network parameter (Rs) issued by the public network base station is smaller than the network parameter (Rn) issued by the control base station. If the parameters measured by the terminal satisfy the network reselection condition, the following condition 3 must be satisfied. The specific content of the condition 3 is as follows:
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 and protection quantity;
qoffset: the public network compensation value is brought down in the system information;
rn: the R value of the management and control network;
qmeas, n: the SS-RSRP value of the management and control network actually measured by the terminal;
qoffset: offset value of the management and control network and protection amount;
qoffset: the network compensation value of the management and control network is brought down in the system information.
The condition 3 may also be referred to as a network reselection R criterion, and in order to make the Rs parameter smaller than the Rn parameter, the following setting requirements must be met when setting the operating parameters of the governing base station, where the setting requirements are to define the parameters in the condition 3. The method specifically comprises the following steps: the (Qmeas, n) parameter is greater than the (Qmeas, s) parameter, similar to the above condition 2-mentioned (SS-RSRP) parameter definition, and will not be described in detail herein; the (Qoffset) parameter is less than the (QHyst) parameter, and particularly, the number of the (Qoffset) parameter is less than the (QHyst) parameter, and the (Qoffset) parameter is set to be a negative value under the general condition; the (qoffsetemp) parameter is not less than the (qoffsetemp) parameter, and is not specifically less than the number of the (qoffsetemp) parameters, which is not limited in the present application.
According to the above mode, the network parameter (Rs) issued by the public network base station can be smaller than the network parameter (Rn) issued by the control base station. The terminal can re-access the management and control base station as long as the terminal starts parameter measurement of network reselection within the preset reselection trigger time. The preset reselection trigger time may be set as a dynamic parameter, for example, the value range may be (0 to 30) seconds, and it should be noted that how many values of the preset reselection trigger time are specifically set is not limited in this application. The preset reselection trigger time may be automatically adjusted according to different reselection states of the terminal, for example, when the terminal does not reselect the management and control base station, the preset reselection trigger time may be set to a minimum value in a value range; when the management and control base station is reselected, the preset reselection trigger time may be set to a maximum value within a value range. The smaller the preset reselection trigger time is, the faster the terminal reselects the management and control base station, and the shorter the time is; the larger the preset reselection trigger time is, the longer the terminal resides in the management and control base station after reselecting the management and control base station.

Specifically, when the above-mentioned working parameters to this management and control base station are set up, the tracking area code may be set to the form of automatically updating according to the preset time, and this preset time may be thirty minutes, and how long this tracking area code is specifically updated once, and it needs to be set up according to actual conditions, and this application does not limit this. When the Tracking Area code is updated, the terminal sends a Tracking Area Update (TAU) request to the management and control platform, and the management and control platform receives the Tracking Area update request and then can acquire a network Identifier of the terminal, where the network Identifier may be GUTI (global Unique Temporary UE Identifier) or SUCI (hidden user Identifier) information, where the network Identifier represents a dynamic Identifier allocated to the terminal by the public network base station and uniquely identifies network information of the terminal under the public network base station.
S403, according to the network identification of the terminal, issuing an identity response signaling to the terminal.
S404, receiving a reply message reported by the terminal, wherein the reply message comprises: identity information of the terminal.
Specifically, according to the GUTI/SUCI information, the management and control platform may issue an identity response signaling to the terminal in a plaintext manner. After receiving the identity response signaling, the terminal can adopt direct reading integrity protection to reply the identity response message and send the reply message to the control platform.
S405, according to the identity identification information of the terminal, signaling for rejecting the tracking area updating request is issued to the terminal.
Specifically, the reply message includes the id information of the terminal, such as SUPI (SUbscription Permanent Identifier), IMEI (International Mobile Equipment Identity), and other information. Wherein the SUPI is used to represent a unique permanent identity for a user in a 5G network, similar to the IMSI in LTE networks (4G). After obtaining the information of SUPI, IMEI, etc., the management and control platform may issue a signaling for rejecting the tracking area update request to the terminal, and after the terminal receives the signaling for rejecting the tracking area update request, the terminal abandons the TAU procedure and indicates that the TAU procedure cannot be completed.

s501, determining whether the terminal is an illegal terminal according to the identity information of the terminal.
The illegal terminal may be an unauthorized terminal in the management and control area or an illegally used terminal. The list of the legal terminal can be stored in the database of the management and control platform in advance, the list of the legal terminal comprises the identity identification information of a plurality of legal terminals, the obtained identity identification information of the terminal can be matched with the list of the legal terminal, if the identity identification information of the terminal is in the list of the legal terminal, the terminal is proved to be the legal terminal, and if the identity identification information of the terminal is not in the list of the legal terminal, the terminal is proved to be the illegal terminal.
And S502, if the terminal is not an illegal terminal, issuing a release signaling to the terminal.
Specifically, when the terminal is a legal terminal, the management and control platform may issue a release signaling to the terminal, so that the terminal may 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, so that the management and control platform can be directly released when the terminal in the released terminal list sends the tracking area updating request next time without sending the flow of the identity response signaling to the terminal in the released terminal list. Therefore, the safety of the information in the control area can be ensured, and the legal terminals in the control area can normally communicate.
