[0042] In order to enable those skilled in the art of the present technology to better understand the technical solutions in one or more embodiments of this specification, the following will clearly and completely describe the technical solutions in one or more embodiments of this specification with reference to the accompanying drawings in one or more embodiments of this specification. Obviously, the described embodiments are only a part of the embodiments of this specification, rather than all the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this document.
[0043] It should be noted that the description of the embodiments of the present invention is only for more clearly explaining the technical solutions of the embodiments of the present invention, and does not constitute a limitation on the technical solutions provided by the embodiments of the present invention.
[0044] Figure 1 The schematic diagram of a system logic interface according to an embodiment of the present invention is shown, as shown in the figure:
[0045] The A-type interface is responsible for: the security server is responsible for the access control of the module, the establishment of a trusted channel, forwarding the authentication and related events to the connection management platform, and monitoring and controlling the behavior of the terminal.
[0046] The B-type interface is responsible for: the communication between the security client embedded in the GSM-R module and the backend security server before the specific service data is transmitted.
[0047] The C-type interface is responsible for: sending the Internet of Things terminal data to the backend service, sending the backend service data to the Internet of Things terminal, notifying the Internet of Things terminal of the data sending window (start sending time, end sending time, sending interval), and waking up the GSM-R module of the terminal to send emergency data.
[0048] The D-type interface: is divided into two categories: a service type interface and a management and control type interface according to the data content.
[0049] Service type interface
[0050] It is mainly used for the reporting, reply, and confirmation of service data between the module and the connection management platform.
[0051] Management and control type interface
[0052] Used for the GSM-R module to power on and notify the platform, the module to confirm the control instructions sent by the platform, the platform to send the service redirection address instruction to the GSM-R module, time synchronization setting (the platform sends the time calibration method instruction to the module), the platform to notify the GSM-R module to go offline, the platform to send the policy setting service data collection time and frequency to the GSM-R module, and the platform to regularly notify the GSM-R module to re-authenticate.
[0053] Interface E is responsible for: in the communication from the sensing terminal to the connection management platform, the sensing terminal gives the data to the GSM-R module, the GSM-R module encrypts and protects the data, transmits it to the security server, and the security server then forwards the data to the connection management platform.
[0054] For example, the GSM-R module collects sensor data and sends the data to the connection management platform:
[0055] The built-in security module of the GSM-R module encrypts and encapsulates the IP packet sent to the management platform to form a new encrypted IP packet;
[0056] Send the encrypted IP packet to the security server through the secure communication tunnel;
[0057] The security server decrypts and performs integrity verification on the received IP packet;
[0058] After successful decryption and passing the verification, send the IP packet to the connection management platform.
[0059] Figure 2 Shows the flowchart of a traffic management method for a GSM-R network according to an embodiment of the present invention; as Figure 2 shown, the traffic management method includes:
[0060] S20. Obtain the train running speed and the coverage range of the cell where the train is connected;
[0061] Specifically, the base station can obtain the information of the cell where the train is connected, know the model of the train, estimate the normal running speed of the train according to the train model, and at the same time, the base station can also obtain the coverage range of the current cell.
[0062] S40. Obtain the time required for the train to leave the cell according to the train running speed and the coverage range of the cell where the train is connected;
[0063] S60. Determine the data sending strategy according to the time required for the train to leave the cell;
[0064] Specifically, when a train accesses the current cell, or when a train accesses an adjacent cell, the IoT sensors within the coverage of the current cell are notified to delay reporting. The length of the delay is the time required for the train to leave the current cell. The judgment subject can be a base station or a connection management platform.
[0065] For example, the management platform connects to the base station that determines the location range of the IoT sensor, and sends the adjusted reporting time and time interval to the IoT sensor through the base station. The reporting time and time interval are adjusted to avoid the time when the train passes through the location range as much as possible.
[0066] The connection management platform can perform statistical analysis based on system data to determine the network resource status and trends in real time. When it is monitored that network resources are approaching or exceeding warning resources, the connection management platform automatically allocates the sending time of a single IoT terminal. The sending time is the optimal time point near its original time interval. Using this time point as the next sending time point can enable the terminal to avoid busy business hours and ensure driving business safety.
[0067] At the same time, the priority level can also be set for the IoT terminal according to the service type;
[0068] The specific settings are to establish an association between the base station kilometer mark and the IoT terminal according to the line data and the deployment location information of the IoT terminal, and to perform hierarchical group management of the base station and GSM-R module;
[0069] After setting the priority, adjust the data sending method of the IoT terminal with the lowest priority when sending data;
[0070] If adjusting the data transmission mode of the IoT terminal with the lowest priority cannot meet the normal running requirements of the train, continue to adjust the data transmission mode of the IoT terminal with the second lowest priority;
[0071] The adjustment includes one or more of the following: sending data in advance, delaying the sending time, or increasing the data sending interval.
[0072] S80, sending data to the Internet of Things terminal through the connection management platform according to the data sending strategy;
[0073] Specifically, the connection management platform sends the data to the GSM-R module, and the data is sent to the Internet of Things terminal through the GSM-R module;
[0074] The connection management platform can also receive data sent from the Internet of Things terminal to the GSM-R module.
[0075] The traffic management method further includes:
[0076] Setting an alarm threshold and a warning threshold on the connection management platform;
[0077] If the current occupancy rate of GSM-R network resources is higher than the threshold, an alarm prompt is sent immediately;
[0078] If it does not exceed the threshold, it is further determined whether the current occupancy rate of GSM-R network resources is higher than the early warning threshold. If it is higher, an early warning prompt is sent.
[0079] For example, when an early warning or an alarm occurs, a stop sending command can be directly issued through the connection management platform to adjust the data sending strategy and avoid busy business hours.
[0080] The present invention provides a traffic management method for a GSM-R network. The traffic management method first obtains the train running speed and the coverage range of the cell accessed by the train; then obtains the time required for the train to leave the cell according to the train running speed and the coverage range of the cell accessed by the train; then determines the data sending strategy according to the time required for the train to leave the cell; and finally sends data to the Internet of Things terminal through the connection management platform according to the data sending strategy. In this embodiment, by setting the data sending strategy of the Internet of Things terminal, the occupancy of network resources is controlled, the problems of network congestion, delay, and packet loss during busy business hours are avoided, the priority of key railway services is guaranteed, and thus the train running safety is ensured.
[0081] Based on the same inventive concept, an embodiment of the present invention further provides a traffic management device for a GSM-R network, which can be used to implement a traffic management method for a GSM-R network described in the above embodiment, as described in the following embodiment: Since the principle of solving problems by the traffic management device for a GSM-R network is similar to that of a traffic management method for a GSM-R network, the implementation of the traffic management device for a GSM-R network can refer to the implementation of the traffic management method for a GSM-R network, and the repeated parts will not be described again. As used below, the term "unit" or "module" can be a combination of software and / or hardware that can implement a predetermined function. Although the device described in the following embodiments is preferably implemented in software, implementation in hardware, or a combination of software and hardware is also possible and contemplated.
[0082] Figure 3 The structural schematic diagram of a traffic management device for a GSM-R network according to an embodiment of the present invention is shown; as Figure 3 shown, the traffic management device includes:

[0086] A policy generation module 60, which determines a data sending policy according to the time required for the train to leave the cell;
[0087] Specifically, when the train accesses the current cell or when the train accesses an adjacent cell, the Internet of Things sensors within the coverage range of the current cell are notified to delay reporting, and the delay duration is the time required for the train to leave the current cell; the subject of this judgment can be the base station or the connection management platform.
[0088] For example, the base station that determines the location range of the Internet of Things sensors by the connection management platform sends the adjusted reporting time and time interval to the Internet of Things sensors through the base station, and the reporting time and time interval should avoid the time when the train passes through this location range as much as possible.
[0089] The connection management platform can perform statistical analysis on the system data to judge the network resource situation and trend in real time. When it monitors that the network resources are close to or exceed the warning resources, the connection management platform automatically allocates the sending opportunity of a single Internet of Things terminal, and the sending opportunity is the optimal time point near its original time interval. Using this time point as the next sending time point can enable the terminal to avoid the busy business period and ensure the safety of train operation services.
[0090] At the same time, the priority can also be set for the Internet of Things terminal according to the service type;
[0091] For the specific setting, according to the line data and the location information of the Internet of Things terminal deployment, an association relationship is established between the kilometer marker of the base station and the Internet of Things terminal, and hierarchical and grouped management is performed on the base station and the GSM-R module;
[0092] After setting the priority, the data sending method of the Internet of Things terminal with the lowest priority is adjusted during data sending;
[0093] If adjusting the data sending method of the Internet of Things terminal with the lowest priority cannot meet the normal driving requirements of the train, then continue to adjust the data sending method of the Internet of Things terminal with the second lowest priority;
[0094] The adjustment includes one or more of the following: sending data in advance, delaying the sending time, or increasing the data sending interval.
[0095] A sending module 80, which sends data to the Internet of Things terminal through the connection management platform according to the data sending policy.
[0096] Specifically, the connection management platform sends data to the GSM-R module, and the GSM-R module sends the data to the Internet of Things terminal;
[0097] The connection management platform can also receive data sent from the Internet of Things terminal to the GSM-R module.
[0098] An embodiment of the present invention provides a traffic management device for a GSM-R network. The traffic management device first obtains the train running speed and the coverage range of the cell accessed by the train through the acquisition module 20; then the calculation module 40 obtains the time required for the train to leave the cell according to the train running speed and the coverage range of the cell accessed by the train; then the policy generation module 60 determines a data sending policy according to the time required for the train to leave the cell; finally, the sending module 80 sends data to the Internet of Things terminal through the connection management platform according to the data sending policy. This embodiment controls the occupation of network resources by setting the data sending policy of the Internet of Things terminal, avoids network congestion, delay, and packet loss problems during peak business hours, ensures the priority of railway key services, and thus ensures the safety of train operation.

[0100] The traffic management device further includes:
[0101] The alarm module 90 sets an alarm threshold and a warning threshold in the connection management platform; if the current occupation rate of GSM-R network resources is higher than the threshold, an alarm prompt is immediately sent; if it does not exceed the threshold, it is further determined whether the current occupation rate of GSM-R network resources is higher than the warning threshold, and if so, a warning prompt is sent.
