[0041] In order to enable those skilled in the art 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 in conjunction with 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.

[0042] It should be noted that the embodiments described in the present invention are only for more clearly explaining the technical solutions of the embodiments of the present invention, and do not constitute a limitation to the technical solutions provided by the embodiments of the present invention.

[0043] Figure 1 The figure shows a schematic diagram of a system logic interface according to an embodiment of the present invention, as shown in the figure:

[0044] Type A interfaces are 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.

[0045] Type B interfaces are 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.

[0046] Type C interfaces are 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 for the terminal to send emergency data.

[0047] Type D interfaces: Are divided into two categories, namely service interfaces and management and control interfaces according to the data content.

[0048] Service interfaces

[0049] Are mainly used for the reporting, reply, and confirmation of service data between the module and the connection management platform.

[0050] Control interface

[0051] 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 acquisition time and frequency of the policy setting service data to the GSM-R module, and the platform to regularly notify the GSM-R module to re-authenticate.

[0052] 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.

[0053] For example, the GSM-R module collects sensor data and sends the data to the connection management platform:

[0054] The security module built in the GSM-R module encrypts and encapsulates the IP packet sent to the management platform to form a new encrypted IP packet;

[0055] Send the encrypted IP packet to the security server through the secure communication tunnel;

[0056] The security server decrypts and performs integrity verification on the received IP packet;

[0057] After successful decryption and passing the verification, send the IP packet to the connection management platform.

[0058] 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:

[0059] S20. Obtain the train timetable, and obtain the departure time, traveling speed, and traveling route according to the train timetable;

[0060] When encountering bad weather, disasters, train accidents and other unexpected situations, the train cannot operate according to the normal train operation plan, and the train operation plan needs to be adjusted accordingly according to the actual emergency.

[0061] Specifically, the connection management platform obtains the updated train timetable, obtains the train number and traveling route according to the train timetable, knows the train type according to the train number, and knows the usual traveling speed according to the train type.

[0062] S40. Determine the time when the train arrives at the sensing range of each IoT terminal according to the departure time, traveling speed, and traveling route;

[0063] S60. Determine a data sending strategy according to the time and the historical usage of the GSM-R network;

[0064] Specifically, comprehensively evaluate the change of network resources according to the time when each Internet of Things terminal's sensing range is reached and the historical GSM-R network occupancy. If the network resources are relatively tight, adjust the data sending strategy in advance through the platform.

[0065] For example, the connection management platform determines the base station within the location range of the Internet of Things sensor, and sends the adjusted reporting time and time interval to the Internet of Things sensor through the base station. The reporting time and time interval should try to avoid the time when the train passes through this location range.

[0066] It is also possible to set priorities for the Internet of Things terminals according to the service type;

[0067] Specifically, according to the line data and the location information of the Internet of Things terminal deployment, establish an association relationship between the kilometer marker of the base station and the Internet of Things terminal, and perform hierarchical and grouped management on the base station and the GSM-R module;

[0068] After setting the priorities, adjust the data sending method of the Internet of Things terminal with the lowest priority when sending data;

[0069] 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, continue to adjust the data sending method of the Internet of Things terminal with the second lowest priority;

[0070] The adjustment includes one or more of the following: sending data in advance, delaying the sending time, or increasing the data sending interval.

[0071] S80. According to the data sending strategy, send data to the Internet of Things terminal through the connection management platform;

[0072] 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;

[0073] The connection management platform can also receive the data sent from the Internet of Things terminal to the GSM-R module.

[0074] The traffic management method further includes:

[0075] Set an alarm threshold and a warning threshold on the connection management platform;

[0076] If the current GSM-R network resource occupancy rate is higher than the threshold, immediately send an alarm prompt;

[0077] If the threshold is not exceeded, further determine whether the current GSM-R network resource occupancy rate is higher than the warning threshold. If it is higher, send a warning prompt.

[0078] For example, when a warning or 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.

[0079] The present invention provides a traffic management method for a GSM-R network. The traffic management method first obtains a train timetable, and obtains the departure time, traveling speed, and traveling route according to the train timetable; then determines the time when the train arrives at the sensing range of each Internet of Things terminal according to the departure time, traveling speed, and traveling route; then determines a data sending strategy according to the time and the historical usage of the GSM-R network; finally, according to the data sending strategy, sends data to the Internet of Things terminal through the connection management platform. In this embodiment, the occupancy of network resources is controlled by setting the data sending strategy of the Internet of Things terminal, avoiding problems such as network congestion, delay, and packet loss during busy business hours, ensuring the priority of key railway services, and thus ensuring the safety of train operation.

[0080] 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 devices described in the following embodiments are preferably implemented in software, implementation in hardware, or a combination of software and hardware is also possible and contemplated.

[0083] Specifically, the connection management platform acquires the updated train timetable, obtains the train number and traveling route according to the train timetable, knows the train type according to the train number, and knows the usual traveling speed according to the train type.

[0084] The calculation module 40 determines the time when the train arrives at the sensing range of each Internet of Things (IoT) terminal according to the departure time, traveling speed, and traveling route.

[0085] The policy generation module 60 determines a data transmission policy according to the time and the historical usage of the GSM-R network.

[0086] Specifically, the change of network resources is comprehensively evaluated according to the time when the train arrives at the sensing range of each IoT terminal and the historical GSM-R network occupancy. If the network resources are relatively tight, the data transmission policy is adjusted in advance through the platform.

[0087] For example, the connection management platform determines the base station within 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 should avoid the time when the train passes through this location range as much as possible.

[0088] The priority can also be set for the IoT terminal according to the service type.

[0089] Specifically, according to the line data and the IoT terminal deployment location information, an association relationship is established between the kilometer marker of the base station and the IoT terminal, and hierarchical and grouped management is performed on the base station and the GSM-R module.

[0090] After setting the priority, the data transmission method of the IoT terminal with the lowest priority is adjusted during data transmission.

[0091] If adjusting the data transmission method of the IoT terminal with the lowest priority cannot meet the normal driving requirements of the train, the data transmission method of the IoT terminal with the second lowest priority is continued to be adjusted.

[0092] The adjustment includes one or more of the following: sending data in advance, delaying the sending time, or increasing the data transmission interval.

[0093] The sending module 80 sends data to the IoT terminal through the connection management platform according to the data transmission policy.

[0094] Specifically, the connection management platform sends the data to the GSM-R module, and the data is sent to the IoT terminal through the GSM-R module.

[0095] The connection management platform can also receive the data sent from the IoT terminal to the GSM-R module.

The traffic management device first obtains a train schedule through an acquisition module 20, and obtains the departure time, traveling speed, and traveling route according to the train schedule; then, through a calculation module 40, determines the time when the train arrives at the sensing range of each Internet of Things terminal according to the departure time, traveling speed, and traveling route; then, a policy generation module 60 determines a data sending policy according to the time and the historical usage of the GSM-R network; finally, a sending module 80 sends data to the Internet of Things terminal through a connection management platform according to the data sending policy. This embodiment controls the occupation of network resources by setting a data sending policy for the Internet of Things terminal, avoids problems such as network congestion, delay, and packet loss during peak business hours, ensures the priority of key railway services, and thus guarantees the safety of train operation.
