An embodiment of the present invention provides a vehicle-road cooperative management system, as shown in fig. 1, including: a terminal 01 and a Mobile Edge Computing (MEC) server 02.
Specifically, the terminal 01 is configured to obtain data information.
The data information comprises signature information, traffic information and attribute information of the terminal, the traffic information is used for indicating road conditions related to the terminal, the signature information is used for verifying the legality of the terminal, and the attribute information is used for indicating the type of the terminal.
The terminal 01 may be a vehicle terminal 011, a pedestrian terminal 012, or a roadside terminal 013. The vehicle terminal 011 may be an On Board Unit (OBU), such as a car navigation system, for recording a driving route of a vehicle and positioning a position of the vehicle; the pedestrian terminal 012 can be various handheld devices or wearable devices with communication functions, for example, the handheld device can be a smart phone, and the wearable device can be a smart bracelet, and is used for recording the traveling route of a pedestrian and positioning the pedestrian; the roadside terminal 013 may be a Road Side Unit (RSU), a traffic signal lamp, a traffic sign, a camera, and other devices, and is used to indicate traffic in a certain area or record road conditions in a certain area. The terminal 01 may be used to send data information to the MEC server 02.
The MEC server 02 is a computer server located at an edge of a core network, and may be one server in a server cluster (composed of a plurality of servers), a chip in the one server, a system on chip in the one server, or may be implemented by a Virtual Machine (VM) deployed on a physical machine, which is not limited in this embodiment of the present application. The MEC server 02 may be configured to determine a traffic optimization policy according to the traffic information and transmit the traffic optimization policy to the terminal 01.
The MEC server 02 is further used for sending a traffic optimization strategy to the terminal 01;
and the terminal 01 is further used for receiving the traffic optimization strategy sent by the MEC server 02.
Optionally, after receiving the data information recorded by the terminal 01 in a certain area, the MEC server 02 may determine a traffic optimization strategy in the area according to the data information sent by the terminal 01, so as to improve traffic transportation efficiency in the area and reduce traffic accidents.
Optionally, as shown in fig. 1, the vehicle-road cooperative management system further includes a cloud center 03 and a base station 04. The cloud center 03 may be configured to receive the traffic optimization strategies determined by the MEC server 02 in the multiple regions, and determine a total traffic optimization strategy including the multiple regions according to the traffic optimization strategies of the multiple regions. And the base station 04 is configured to provide network connection for the terminal 01 and provide a data transmission service for the terminal 01 and the MEC server 02.
For example, the specific workflow of the vehicle-road cooperative management system may be: if A is divided into an X area, a Y area and a Z area, the X area is provided with a first MEC server, the Y area is provided with a second MEC server, and the Z area is provided with a third MEC server, then the first MEC server receives data information of all pedestrian terminals, vehicle terminals and roadside terminals in the X area, the second MEC server receives data information of all pedestrian terminals, vehicle terminals and roadside terminals in the Y area, and the third MEC server receives data information of all pedestrian terminals, vehicle terminals and roadside terminals in the Z area. And the first MEC server, the second MEC server and the third MEC server respectively determine traffic optimization strategies in corresponding areas according to the received data information and send the determined traffic optimization strategies to the cloud center. The cloud center receives the traffic optimization strategies sent by the first MEC server, the second MEC server and the third MEC server, and formulates the traffic optimization strategy of the place A according to the traffic optimization strategies.
It should be noted that the terminal 01 and the MEC server 02 shown in fig. 1 are merely exemplary, and in practice, the vehicle-road cooperative management system further includes another terminal 01 and MEC server 02, which is not shown in fig. 1. The data information of the pedestrian terminal comprises a travel route and a position of a pedestrian; the data information of the vehicle terminal comprises a traveling route and a position of the vehicle; the data information of the roadside terminal comprises the display color of the traffic signal lamp, the conversion time of the traffic signal lamp, the conversion sequence of the color of the traffic signal lamp and the like, the indication content of the traffic sign, such as the prohibition of parking, the prohibition of turning left and right and the like, and the data information also comprises the image and the video information shot by the camera. The MEC server is actually a data center positioned on the wireless access network side, and the application of the MEC server can reduce the time delay of data information processing of the terminal and avoid network congestion when the data volume is large; the cloud center has the same function as the traditional data center and is used for operating and processing a large amount of data.
As shown in fig. 2, an embodiment of the present invention provides a vehicle-road cooperative management method, which is applied to the vehicle-road cooperative management system shown in fig. 1, and includes:
s101, the terminal acquires data information.
The data information comprises signature information, traffic information and attribute information of the terminal, the traffic information is used for indicating road conditions related to the terminal, the signature information is used for verifying the legality of the terminal, and the attribute information is used for indicating the type of the terminal.
Specifically, because the terminal may be different types of devices such as a vehicle terminal, a pedestrian terminal, a roadside terminal, and the like, the data information acquired by the terminal also includes different information according to the type of the terminal, for example, the data information of the vehicle terminal includes a traveling route and a position of a vehicle, the data information of the pedestrian terminal includes a traveling route and a position of a pedestrian, the data information of the traffic signal includes a display color of the traffic signal, a change time of the traffic signal, a change sequence of the color of the traffic signal, and the like. Of course, the data information of the different types of terminals is only exemplary, and the terminals may be other types of devices in practice.
It should be noted that the road condition related to the terminal indicated by the traffic information may be different according to different types of terminals, for example, when the terminal is a vehicle terminal, the traffic information may be a traveling route and a location of the vehicle terminal; when the terminal is a traffic light, the traffic information may be a display color of the traffic light, a color change time, and the like. The means for acquiring the data information may be different according to the type of the terminal, for example, the vehicle terminal and the pedestrian terminal may acquire the data information through a built-in navigation device, and the traffic light may acquire the data information through a built-in processor. The above description is only exemplary, and in practice, the terminal may also be another type of device, the traffic information may also include other information, and the device for acquiring data information may also be another device, which is not limited to the present invention.
S102, the terminal sends data information to the MEC server.
Specifically, a security module is arranged in the terminal in the embodiment of the present invention, and is configured to establish a secure connection of an internet protocol security (IPsec) with the MEC server. Therefore, the data information acquired by the terminal can be acquired by the acquisition device in the terminal and then sent to the security module in the terminal, and the security module sends the data information to the MEC server. The acquiring means here may be a navigation means or a processor or the like.
It should be noted that the data information of the terminal is transmitted to the MEC server and needs to be forwarded by the base station. Because the terminal establishes the IPsec security connection with the MEC server through the built-in security module, when the terminal sends data information to the outside through the security module, the security of the data information can be ensured, the confidentiality and the security of data transmission between the terminal and the MEC server are enhanced, the condition that an illegal terminal counterfeits equipment in a lane cooperative management system to acquire the data information of the terminal is avoided, and the data security of the terminal is enhanced.
Optionally, the security module in the terminal in the embodiment of the present invention may be a 5G security module, which may establish a connection with a 5th-Generation (5G) network, establish a 5G network connection for the terminal, and provide a faster network transmission service. Of course, the security module may also be another type of security module, such as a 4G security module, for establishing a connection with a 4th-Generation (4G) network, and the embodiment of the present invention is not limited thereto.
S103, the MEC server receives the data information sent by the terminal.
The data information comprises signature information and traffic information of the terminal, the traffic information is used for indicating road conditions related to the terminal, and the signature information is used for verifying the legality of the terminal.
Specifically, the MEC server is actually a data center located on the wireless access network side, and after the terminal accesses the wireless network provided by the operator through the base station, the MEC server can receive data information sent by the terminal through the base station.
And S104, judging whether the terminal is legal or not by the MEC server according to the signature information.
Specifically, the signature information of the terminal is the identification information of the terminal, and each legal terminal has unique signature information for indicating the validity of the terminal.
The MEC server stores the identity information of the terminal. If the identity identification information stored in the MEC server comprises identity identification information consistent with signature information in the received data information, the terminal sending the data information is legal; and if the identity identification information stored in the MEC server does not include identity identification information consistent with the signature information in the received data information, the terminal sending the data information is illegal.
For example, the identification information stored in the MEC server may be as shown in table 1 below.
TABLE 1
| Serial number | Terminal type | Identity label |
| 1 | Vehicle terminal | ca3142 |
| 2 | Pedestrian terminal | pe3232 |
| 3 | Traffic indicating lamp | li3284 |
| … | … | … |
| N | Camera head | cn8320 |
As shown in table 1 above, if the signature information received by the MEC server is ca3142, the terminal that sent the signature information is legal; if the signature information received by the MEC server is fe3213, the terminal that transmitted the signature information is illegal. Of course, if the signature information is not included in the data information received by the MEC server, the terminal that transmitted the data information is also not legitimate.
It should be noted that the contents in table 1 are only exemplary, the id information of the terminal may be in other different formats, and the contents in table 1 may also change at any time since the number and types of terminals in a certain area are changing constantly. In this case, if the signature information included in the data information is in a correct format, it can be considered that the terminal that transmitted the data information is legitimate. The MEC server can also determine the type of the terminal according to the identification information of the terminal, such as the terminal is a vehicle terminal or a pedestrian terminal.
And S105, if the terminal is legal, the MEC server determines a traffic optimization strategy according to the traffic information.
Specifically, because the MEC server is only used for receiving data information of a terminal in a certain area, if the MEC server determines that the terminal is legal, the MEC server may determine a traffic optimization strategy for the area according to the data information sent by the terminal, where the traffic optimization strategy may include a traveling route of vehicles and pedestrians, and instruction content of a roadside terminal, and the like; color change control of the traffic light may also be included, such as controlling the display color of the traffic light and the interval time of the color change.
For example, if the MEC server is only used to receive the data information of the terminal in the X area, the MEC server may determine the traffic optimization policy in the X area after receiving the data information of all terminals in the area. If the X area comprises a plurality of vehicle terminals, a plurality of pedestrian terminals, a plurality of traffic indicator lights, a plurality of cameras and a plurality of traffic indicators, the MEC server can summarize data information of the plurality of vehicle terminals, the plurality of pedestrian terminals, the plurality of traffic indicator lights, the plurality of cameras and the plurality of traffic indicators, so that a first traffic optimization strategy is determined for the vehicle terminals, the pedestrian terminals, the traffic indicators and other terminals. If the final destination of the vehicle is a first preset position, the MEC server determines that the vehicle needs to pass through a first street according to the traveling route of the vehicle terminal, the MEC server determines that the first street is congested according to the video of the first street shot by the first camera, and determines that a second street is clear according to the video of the second street shot by the second camera. If both the first street and the second street can reach the first preset location, the MEC server may determine a traffic optimization policy for the vehicle, instructing the vehicle to avoid the first street and to travel from the second street to the first preset location.
It should be noted that the first street and the second street are any streets in the X area, and the first preset position is any position in the X area. In practice, the MEC server may also make different first traffic optimization strategies according to different terminal types, which may include an indication of a vehicle terminal travel route, an indication of a pedestrian terminal travel route, an adjustment of a traffic signal lamp conversion strategy, and the like, and details are not repeated here. After receiving traffic information of various terminals, the MEC server can also clean redundant data in the traffic information and filter out useless information in the traffic information, and like a plurality of cameras are arranged in a street, the MEC server can delete repeated videos shot by the plurality of cameras. Of course, before determining the traffic optimization strategy according to the cleaned traffic information, the MEC server may also convert the cleaned traffic information into structured data, and the conversion method of the structured data is the same as that commonly used in the art, and is not described herein again.
Optionally, after step S105, the MEC server may transmit the traffic optimization policy to the terminal.
It should be noted that, when the communication between the MEC server and the cloud center is interrupted, the MEC server executes an operation of sending the traffic optimization policy to the terminal.
S106, the terminal receives the traffic optimization strategy sent by the MEC server.
Specifically, after the MEC server determines the traffic optimization strategy, the terminal can acquire the traffic optimization strategy of the area to which the terminal belongs from the MEC server, and determine the operation of the terminal according to the traffic optimization strategy, if the terminal is a vehicle terminal, the vehicle terminal can select the optimal traveling route according to the traffic optimization strategy, and can avoid violating the indication rules of the traffic indicator light and the traffic sign according to the traffic optimization strategy; if the terminal is a traffic light, the traffic light can change the displayed color according to the traffic optimization strategy, and the change time of the displayed color is determined according to the traffic optimization strategy. Of course, the traffic optimization policy further includes other indication contents according to different types of terminals, and details are not repeated herein.
Optionally, the data information received by the MEC server further includes attribute information, and the attribute information is used to indicate the type of the terminal. As shown in fig. 3, after step S103, the method may further include:
s103, 103A, establishing the special bearing corresponding to the attribute information for the terminal.
Specifically, when the terminal is a vehicle terminal, the type of the vehicle terminal may further include a private car, an ambulance, a fire truck, a police car, and the like, and the attribute information may be used to indicate the type of the vehicle terminal. When the MEC server determines that the terminal sending the attribute information is the ambulance according to the attribute information, because the ambulance may carry telemedicine equipment and the required network quality is high, after the MEC server determines that the terminal is the ambulance, the MEC server can reallocate a large bandwidth for the ambulance so as to ensure the network quality of the ambulance; or a special bearer is established for equipment needing to establish network connection in the ambulance, so that the network quality of the ambulance is ensured. Of course, when the terminal is other special equipment, such as a police car or a fire truck, the MEC server may also reallocate a larger bandwidth for the terminal or establish a dedicated bearer for the terminal.
It should be noted that, because the MEC server is actually a data center located at the edge of the core network, the MEC server is actually a part of the core network, and therefore the MEC server can establish a corresponding dedicated bearer for the terminal or allocate a larger bandwidth. The attribute information may also be a flag information, and after determining that the attribute information sent by the terminal carries the flag information, the MEC server may establish a dedicated bearer for the terminal.
Optionally, as shown in fig. 4, after step S105, the method further includes:
s201, if the terminal is legal, the MEC server sends a response message to the terminal.
Wherein, the response message is used for indicating that the terminal is legal.
Specifically, if the MEC server determines that the terminal is legal, a response message is sent to the terminal to indicate that the terminal is legal, and the MEC server can receive the data information sent by the terminal and determine a traffic optimization strategy for the terminal according to the received data information.
Of course, if the terminal is illegal, the MEC server sends a rejection message to the terminal for instructing the MEC server to reject receiving the data information of the terminal.
S202, receiving a response message sent by the MEC server.
Wherein, the response message is used for indicating that the terminal is legal.
Specifically, after receiving the response message sent by the MEC server, the terminal may continue to send data information to the MEC server, and the MEC server determines the traffic optimization policy for the terminal.
And S203, sending a negotiation request to the MEC server.
Wherein the negotiation request is for requesting a secure connection to be established with the MEC server.
Specifically, after receiving the response message and determining that the verification is passed, the terminal may send a negotiation request to the MEC server, and request to establish a secure connection with the MEC server.
And S204, receiving a negotiation request sent by the terminal, and establishing a secure connection with the terminal according to the negotiation request.
Specifically, after receiving the negotiation request sent by the terminal, the MEC server may negotiate with the terminal to determine a key, and encrypt data information transmitted between the terminal and the MEC server through the key to ensure data security.
For example, the secure connection between the terminal and the MEC server in the embodiment of the present invention may be an IPsec connection. The process of establishing the IPsec connection between the terminal and the MEC server includes an Internet Security Association and Key Management Protocol (ISAKMP) security association negotiation stage and an IPsec security association negotiation stage, wherein the ISAKMP security association negotiation stage is used for negotiating contents such as an authentication mode, an encryption algorithm, and a negotiation mode used between the terminal and the MEC server, and the IPsec security association negotiation stage is used for negotiating contents such as an encapsulation technology and a transmission mode used between the terminal and the MEC server. The specific negotiation process of the ISAKMP security association negotiation stage and the IPsec security association negotiation stage is the same as the technical means commonly used in the field, and details thereof are not repeated herein.
It should be noted that, in the embodiment of the present invention, data communication between all terminals and the MEC server needs to be forwarded through the base station. Because the data transmission between the terminal and the MEC server is realized by the built-in security module of the terminal, the secure connection between the terminal and the MEC server is also established between the security module and the MEC server.
Optionally, after step S105, the method further includes:
s301, if the communication between the MEC server and the cloud center is normal, the MEC server sends data information to the cloud center.
Specifically, when the communication connection between the MEC server and the cloud center is normal, the MEC server may forward the received data information to the cloud center. Of course, the MEC server may also send the traffic optimization policy determined by the MEC server to the cloud center.
S302, the cloud center determines a traffic optimization strategy according to the data information sent by the MEC server.
Specifically, each MEC server is responsible for receiving data information of terminals in a certain area, the data information received by different MEC servers is different, and the vehicle-road cooperative management system only comprises one cloud center. Therefore, the cloud center can receive data information sent by the MEC servers in the multiple regions, and determine the traffic optimization strategies of the multiple regions according to the received multiple data information. Of course, when the MEC server sends the traffic optimization policy to the cloud center, the cloud center may integrate the traffic optimization policies of the plurality of MEC servers, and then determine a traffic optimization policy including traffic conditions of a plurality of regions.
