The gate management method and system and the gate control management system provided by the disclosure can be used for directly using a 5G mobile terminal, controlling the opening and closing of the gate by using the cell switching flow in a measurement-free mode by connecting a 5G base station covering the gate and using the 5G mobile terminal between cells of the base station, and realizing a fast and convenient gate inlet and outlet flow.
Fig. 1 is a flowchart of a gate management method according to an embodiment of the disclosure. As shown in fig. 1, the gate management method includes:
step S1, the 5G base station (5G Node B, abbreviated to gNB) detects that the mobile terminal accesses the intra-gate cell.
Wherein, the inside district of floodgate machine includes: and one of the cells corresponding to all gates covered by the 5G base station.
In practical application, the mobile terminal is connected with the cell inside the gate machine in a mode of inserting the mobile terminal socket of the gate machine, when the mobile terminal is inserted into the mobile terminal socket of the gate machine, the signal of the cell outside the gate machine can be weakened sharply, the mobile terminal receives the signal of the cell inside the gate machine, the original cell is the cell outside the gate machine, the cell switching process of the cell inside the gate machine serving as a switching object is carried out, and the 5G base station can detect that the mobile terminal is accessed into the cell inside the gate machine after the switching is completed.
Step S2, the 5G base station sends Access event information to a Location Management Function (LMF) node through an Access and Mobility Management Function (AMF).
Wherein the access event information includes: a gate identification and a mobile terminal identification of the mobile terminal.
In practical application, the gate identifier and the identity identifier of the cell corresponding to the gate identifier have global uniqueness. The position management function node can directly determine a gate accessed by the mobile terminal according to the gate identifier, and the specific implementation flow is that the 5G base station is connected with the gate in a fixed line mode, the gate identifier acquisition function configured in the gate is used, when the mobile terminal is detected to be accessed, the gate identifier is actively acquired, and then the gate identifier is sent to the position management function node through the access and mobile management function node; the position management function node can determine a corresponding gate according to a gate internal cell accessed by the mobile terminal, and the gate identifier and the identity identifier of the gate internal cell can be configured in a centralized manner through a background system.
The access event information may also include a current time stamp for subsequent recording of the access event. The mobile terminal identification may include: the user hidden Identifier (SUCI), the user Permanent Identifier (SUPI), the user Number (SUNum), and the Temporary Mobile Subscriber Identity (TMSI) have unique identities.
And step S3a, after receiving the access event information, the position management function node sends a gate opening request to the background system, so that the background system can open the corresponding gate according to the gate opening request.
Wherein the gate open request comprises: a gate identifier and a mobile terminal identifier.
In practical application, the background system can judge and record whether the current operation attribute is 'in' or 'out' according to the access history of the mobile terminal, and stores a gate opening request as a basis for subsequently collecting traffic fees or verifying and selling tickets and other operations.
For the gate of the traffic system, the identity of the cell in the gate can be set to realize that a single gate is configured to enter or leave two working modes, so that the current operation attribute does not need to be recorded as 'enter' or 'exit', and the background system can directly judge the current operation attribute according to the identity of the cell. For example, for a gate entering a mode, the corresponding ID is set to be even or a specific prefix or suffix representing entering is added; for the gate in the exit mode, the corresponding ID is set to be odd number or a specific prefix or suffix representing exit is added. Therefore, the working state of the gate can be changed by changing the identity of the cell in the gate.
The disclosed embodiment provides a gate management method, which can be used for controlling the opening and closing of a gate by switching a 5G mobile terminal between a gate external cell and a gate internal cell through a 5G base station connected with a coverage gate by directly using the 5G mobile terminal.

Step S5, the 5G base station sends system information to the mobile terminal according to the received cell switching preparation information, so that the mobile terminal and the 5G base station can perform a cell switching process subsequently.
In practical applications, the 5G base station may transmit the System Information to the mobile terminal through a System Information Block (SIB 4) of the fourth type.
In some embodiments, the system information includes: a measurement-free flag of the last cell to which the mobile terminal is connected.
The measurement-free mark is used for the mobile terminal to directly construct the optimal measurement result aiming at the previous cell without actual quality measurement based on the measurement-free mark.
In practical application, the last cell connected with the mobile terminal is an external cell of the gate. The measurement-free mark is used for indicating that the mobile terminal does not need to perform quality measurement on the corresponding cell, and the measurement-free mark may include: an identity of a cell and an indicator indicating that the mobile terminal is not performing quality measurements on the cell.
After receiving the system information, the mobile terminal prepares for cell switching, including filling the measurement reports of the cells corresponding to the measurement-free marks received from the 5G base station, and filling the values in the measurement reports to optimal values. The method realizes that an optimal measurement report result is directly constructed according to the measurement-free mark without actual measurement.
The system information may further include: a cell quality rating and a cell priority, and both the quality rating and the priority are set to the highest level.
In the process of cell switching, for data sent from the network side to the mobile terminal, the access and mobility management function node caches the data and sends the data to the mobile terminal when the mobile terminal returns to a gate external cell.
For the data sent from the mobile terminal to the network side, the mobile terminal caches the data submitted by the built-in application to the network when receiving the system information, and sends the data to the network side when the mobile terminal returns to the external cell of the gate.
