In the embodiment of the present application, the terminal determines a first parameter value corresponding to a configuration parameter at a current time, then matches the first parameter value with a parameter value set, determines a second parameter value matching the first parameter value in the parameter value set, and finally, the terminal may send a message according to a first sending frequency corresponding to the second parameter value.

In the following, a method for sending a message in the present application is described in detail through an embodiment, please refer to fig. 3, where an embodiment of the method for sending a message in the embodiment of the present application may include a plurality of terminals in a communication system of an internet of vehicles, and an interaction between any one of the terminals and a server is taken as an example in the present embodiment for description.

Step 301, the terminal initiates a start connection (on-boot connection) to the CF, the CF feeds back a response to the terminal, and the terminal is connected with the CF.

Step 302, the CF authorizes the terminal to use the related services of the car networking and sends communication parameters (including but not limited to radio resources, authorized services, or IP address of V2X application server, etc.) to the terminal;

and step 303, the terminal is connected with the application server through the base station according to the IP address of the application server, and reports the ID of the terminal and the equipment type of the terminal to the application server.

The device types include, but are not limited to, Road Side Unit (RSU), Vehicle User Equipment (V-UE), and Pedestrian User Equipment (P-UE).

It should be noted that steps 301 to 303 are optional steps, and if the terminal and the application server have already established a connection, step 304 is directly performed without performing steps 301 to 303 described above.

Step 304, the application server configures first frequency configuration information, where the first frequency configuration information includes at least one configuration parameter, a parameter value set of the at least one configuration parameter, and a first sending frequency corresponding to each first parameter value in the first parameter value set.

Each of the at least one configuration parameter corresponds to a set of parameter values, e.g., a first configuration parameter corresponds to a first set of parameter values, a second configuration parameter corresponds to a second set of parameter values, etc.

The application server configures first frequency configuration information, for example, the at least one configuration parameter includes, but is not limited to, at least one of speed, traffic, and geographic location, and each configuration parameter has a corresponding set of parameter values, and each parameter value in the set of parameter values has a corresponding first transmission frequency.

For example, the services include, but are not limited to, regular services, traffic light services, alarm services, and fault services.

Geographic locations include, but are not limited to, high speed, urban, suburban, crossroads, and the like.

In a first possible implementation manner, the configuration parameter may further include a device type, for example, a parameter value set corresponding to the device type includes a drive test unit and a vehicle device (a commercial vehicle-mounted device, a truck-mounted device, and the like), and each parameter value corresponds to a first sending frequency, for example, the first sending frequency corresponding to the drive test unit is 30Hz, and when the device type is the drive test unit, the sending frequency of the sent message is a fixed value; when the device types are vehicle devices and pedestrian devices, the sending frequency of the sent messages can be multiple, different sending frequencies correspond to different parameter values of the configuration parameters, and the first sending frequency corresponding to the vehicle-mounted device is 10 Hz. Or, different on-board devices correspond to different transmission frequencies, for example, the first transmission frequency corresponding to the on-board device of the commercial vehicle is 10Hz, and the first transmission frequency corresponding to the on-board device of the truck is 5 Hz.

It should be noted that, in the embodiment of the present application, specific data corresponding to the device type and the first transmission frequency are all exemplified and do not constitute a limiting description of the present application.

In a second possible implementation manner, the application server may configure, for the terminal, first frequency configuration information corresponding to the device type according to the device type reported by the terminal. The frequency configuration information may be exemplified in the form of a configuration information table, and the frequency configuration information is exemplified in the following 3 examples.

1. The first frequency configuration information includes 1 configuration parameter, and when the terminal is a vehicle quantity device and the configuration parameter is a speed, the first frequency configuration information is as shown in table 1 below:

TABLE 1

Terminal speed (km/h)	Message sending frequency (Hz)
		0～20	2
20～50	5
		50～80	10
80～120	20
		120 to above	30

2. The first frequency configuration information includes 2 configuration parameters, the configuration parameters include a geographic location and a speed, and the first frequency configuration information is shown in table 2 below:

TABLE 2

3. The first frequency configuration information includes 3 configuration parameters, where the configuration parameters include geographic location, speed, and service, and the first configuration information is shown in table 3 below:

TABLE 3

In table 3, the set of parameter values corresponding to the services is a set of service ID values, and different service ID values in the set of service ID values correspond to different services. For example, "700" represents regular traffic, "710" represents traffic light traffic, "720" represents alarm traffic, "730" represents fault traffic, "etc., and the traffic and ID values in table 3 are illustrative and not meant to be a limiting description of the present application.

The configuration parameters and the parameter value sets corresponding to each configuration parameter in tables 1, 2 and 3 are all exemplified and do not limit the present application.

It should be understood that the first frequency configuration information in the embodiment of the present application includes at least one configuration parameter, the frequency configuration parameters in table 1, table 2 and table 3 are only for illustration and do not make a limiting description of the present application, and the configuration parameter in the first frequency configuration information may be at least one of the above configuration parameters. For example, in another example, the first frequency configuration information may also include only the configuration parameter of the service, or may also include only the configuration parameter of the geographic location, or may also include the service and the geographic location, and so on.

Step 305, the terminal receives the first frequency configuration information sent by the server, and determines a first parameter value corresponding to the configuration parameter at the current time.

In a first example, the terminal receives first frequency configuration information sent from the application server, where the first frequency configuration information is shown in table 1, and the terminal detects that the speed value at the current time is 70 according to the configuration parameters (speed) in the first frequency configuration information.

In a second example, the first frequency configuration information is shown in table 2, and the terminal determines the current geographic location (e.g., an urban area) according to the configuration parameters (geographic location and speed) in the first frequency configuration information, and detects the speed value (e.g., 70) at the current time.

In a third example, the first frequency configuration information is shown in table 3, when the configuration parameters include a geographic location, a speed and a service, the terminal determines the service (e.g., a conventional service) at the current time, determines the current geographic location (e.g., an urban area), and detects a speed value (e.g., 80) at the current time.

Step 306, the terminal matches the first parameter value with the parameter value set, and determines a second parameter value matched with the first parameter value in the parameter value set.

In a first example, when the first frequency configuration information is shown in table 1, the terminal matches a currently detected first speed value (e.g. 70) with the set of speed values in table 1, determines a second speed value matching the first speed value in the set of speed values, e.g. the currently detected speed is 70, and the currently detected speed is a second speed value (e.g. 50-80) matching the set of speed values in table 1.

In a second example, when the first frequency configuration information is shown in table 2, the configuration parameters include geographic locations, and in the first frequency configuration information, a parameter value of each geographic location corresponds to N speed values, each of the N speed values corresponds to a first transmission frequency, and N is a positive integer greater than or equal to 1. In table 2, 2 geographical locations are included, such as downtown and high speed.

It should be understood that the geographical locations and the speed value sets corresponding to each geographical location are only illustrated in table 2, and are not meant to be limiting, and of course, the geographical locations may also include intersections, viaducts, and the like, which are not illustrated herein.

The terminal detects a current location (e.g., downtown) and a first speed value (e.g., 70) at the current time.

First, the terminal matches a first location (downtown) at the current time with parameter values (downtown and high speed) of a geographical location, and determines a second location in the first frequency configuration information, the second location being "downtown".

Each geographical location corresponds to N speed values, for example, as shown in Table 2, 5 speed values corresponding to "urban area" are respectively "0-20", "20-50", "50-80", "80-120" and "120-over".

Then, the terminal matches the first speed value 70 at the current time with the N speed values corresponding to the second position, and determines a second speed value "50-80" matching the first speed value 70 among the 5 speed values.

In a third example, the configuration parameter is a service, the parameter value set includes a service ID value set, and the terminal determines a first service currently executed; and matching the ID value of the first service with the service ID set, and determining a second service ID value matched with the first service in the service ID set.

In a fourth example, the first frequency configuration information further includes a priority of configuration parameters, each configuration parameter in the at least one configuration parameter has a corresponding priority, and the service is a configuration parameter with the highest priority.

When the first frequency configuration information is shown in table 2 or 3, and the first frequency configuration information includes at least two configuration parameters, each configuration parameter has a corresponding priority, where a service has the highest priority (first priority), a speed has a second priority, and the like.

The terminal determines a target configuration parameter in at least one configuration parameter according to the priority of the configuration parameter; for example, when the 2 configuration parameters are speed and service, respectively, the terminal determines the configuration parameter with the higher priority level as the target configuration parameter, and adjusts the frequency of the current message according to the first sending frequency corresponding to the second parameter value in the parameter value set of the target configuration parameter. For example, when 2 configuration parameters are speed and service, respectively, the priority level of the service is highest, the terminal determines the first service at the current time, the terminal first matches the first service with the service ID value set in the first frequency configuration information, for example, the first service at the current time is traffic light service, the ID value of the traffic light service is 710, the current first service is matched with the service ID value set, and the matched target service ID value is 710.

And 307, the terminal sends the message according to the first sending frequency corresponding to the second parameter value.

In a first example, referring to table 1, the second parameter value (speed value) is "50 to 80", and when the speed value is "50 to 80", the first transmission frequency in the corresponding message transmission frequencies is "10" according to the correspondence between the parameter value and the message transmission frequency in the first frequency configuration information.

In a second example, referring to table 2, "urban" where the speed values are "50 to 80," the first transmission frequency among the corresponding message transmission frequencies is "10.

In a third example, as shown in table 3, when the first service ID value is "710", the first transmission frequency corresponding to the target service ID value of "710" is "10".

On the basis of the embodiment corresponding to fig. 2, optionally, after receiving the first frequency configuration information, the terminal may further receive second frequency configuration information after update, where the second frequency configuration information is sent from the application server, and is used to indicate that the terminal may send a message according to the second sending frequency after update.

In a possible implementation manner, the terminal sends a target message corresponding to a target service to the server according to a first sending frequency (e.g. 10Hz), for example, the target service is some service requiring special services, such as a failure service, a collision service, and the like.

The application server receives a target message sent by the terminal, wherein the target message is used for indicating the server to update the first frequency configuration information according to the target message to obtain updated second frequency configuration information, and the second frequency configuration information comprises updated second sending frequency.

The application server receives the target message, determines that the current service of the terminal is a fault service, and can configure frequency configuration information, namely updated second frequency configuration information, for the terminal according to the fault service, wherein the second frequency configuration information comprises at least one configuration parameter, and can be understood by referring to table 1, table 2 and table 3. In an application scenario, when the application server receives a target message, it determines a current service of the terminal, which indicates that the terminal is at risk currently, and needs to improve the sending frequency of the message sent by the terminal to ensure the security of the terminal, so that the application server reconfigures frequency information and reconfigured second frequency configuration information, where the second frequency configuration information includes the service and a second sending frequency corresponding to the service, for example, the second frequency configuration information includes a faulty service (ID value is "730"), and the second sending frequency corresponding to the faulty service is 40Hz (first sending frequency is 20 Hz). The second sending frequency is increased compared with the first sending frequency, so that the sending frequency is dynamically adjusted, and the safety of different services is improved.

In the embodiment of the present application, in order to distinguish between the frequency allocation information after update and the transmission frequency, in the present application, "first frequency allocation information" is frequency allocation information before update, "second frequency allocation information" is frequency allocation information after update, a first transmission frequency in the first frequency allocation information is a transmission frequency before update, and a second transmission frequency in the second frequency allocation information is a transmission frequency after update.

And after receiving the second frequency configuration information, the terminal adjusts the sending frequency of the sending message according to the indication of the second frequency configuration information. When the terminal receives the second frequency configuration information, the target service at the current moment is matched with the service in the second frequency configuration information, a second sending frequency (such as 40Hz) corresponding to the 'failure service' in the second frequency configuration information is determined, and the terminal sends a message according to the updated second sending frequency (such as 40 Hz).

In this example, the application server configures the first frequency configuration information for the terminal, and according to the requirement of the actual service, the application server may also update the first frequency configuration information, update the second sending frequency (e.g., 40Hz) corresponding to the target service (e.g., the failed service), the terminal receives the second frequency configuration information and sends the message according to the updated second sending frequency, and the terminal dynamically adjusts the frequency of sending the message according to the indication of the second frequency configuration information, so that the data volume of the broadcast messages of all terminals in the system is reduced, and the security of the vehicle in some special services (e.g., the failed service) can be improved.

In another possible implementation manner, the application server may also update the frequency configuration information for the terminal according to global information and the current service of the terminal, where the global information may be understood as information of a current air interface resource of the application server in the V2X communication system. For example, in the case of the radio resources occupied by all terminals in the current V2X communication system, the transmission frequency of the transmission message is configured uniformly for each of all terminals.

In an application scenario, if the V2X communication system includes a terminal a, a terminal B, and a terminal C in a connected state, if the sending frequency of the current message sent by the terminal a is 10Hz, the sending frequency of the current message sent by the terminal B is 10Hz, the sending frequency of the current message sent by the terminal C is 10Hz, and assuming that the application server does not have currently allocable wireless resources, the server may configure updated second frequency configuration information for each terminal according to the current global information. For example, if the terminal C is currently a failure service, the terminal C sends a target message of the failure service to the application server through the base station according to a sending frequency of 10Hz, where the target message carries an ID of the failure service, and after receiving the target message, the application server determines that the current service of the terminal C is the failure service according to the target message, and if the application server increases the sending frequency of the terminal C, the sending frequencies of the terminal a and the terminal B need to be decreased. The application server reconfigures the sending frequency of the sending message for the terminal A and the terminal B, and sends frequency configuration information A to the terminal A, wherein the frequency configuration information A is used for indicating the terminal A to adjust the current sending frequency of the message to be 5Hz, namely, the sending frequency of the message of the terminal A is reduced from 10Hz to 5 Hz; the application server sends frequency configuration information B to the terminal B, wherein the frequency configuration information B is used for indicating the terminal B to adjust the current message sending frequency to be 5Hz, namely, the message sending frequency of the terminal B is reduced from 10Hz to 5 Hz; the application server configures second frequency configuration information for the terminal C, where the second frequency configuration information includes configuration parameters (fault service) and a second sending frequency corresponding to the fault service, which is 20Hz, that is, the message sending frequency of the terminal C is increased from 10Hz to 20Hz, and the terminal adjusts the message sending frequency to 20Hz according to the updated second frequency configuration information.

To understand the embodiment of the present application, in an application scenario, the terminal D is a vehicle device, a vehicle is driving on a highway, and the terminal D is connected to an application server, the application server sends first frequency configuration information to the terminal D through a base station, where the first frequency configuration information is as shown in table 2 above, that is, the first frequency configuration information includes 2 configuration parameters, that is, speed and position, the terminal a detects that the current speed is "90", acquires that the current position is "high speed", the terminal D matches the current position with a parameter value set (city district and high speed) corresponding to the position in the received first frequency configuration information, determines that the parameter value corresponding to the geographic position is "high speed", matches the speed 90 corresponding to the terminal D itself with a speed value corresponding to the high speed in the first frequency configuration information, as shown in table 2, and the second speed value matched with the first speed 90 of the terminal D itself is (80-120), the message sending frequency corresponding to the second speed value (80-120) is 20Hz, at the moment, the terminal sends the message according to the frequency of 20Hz, and when the running speed of the vehicle is high, the terminal needs to be configured with high sending frequency to ensure that the self state information of the peripheral terminal can be informed at high frequency, so that the running safety of the vehicle is improved. After the vehicle travels to the urban area, the terminal detects that the current speed is 40, the terminal performs matching according to the information shown in table 2, as shown in table 2, when the speed is 40, the terminal matches the speed value set in table 2, determines that the second speed value is (20-50), and the message sending frequency corresponding to the second speed value (20-50) is 5Hz, and when the vehicle travels in the urban area, the vehicle speed is slow, so the frequency of sending the message can be reduced, and the communication and safety of the vehicle can also be guaranteed, at this time, the terminal D broadcasts the message to the surrounding terminals and servers according to 5 Hz. In the embodiment of the application, the terminal can flexibly adjust the sending frequency of the current sending message according to the message sending frequency in the frequency configuration information, so that useless V2X messages can be reduced, and the V2X message transmission is more efficient.

The central server: with respect to the edge servers, the central server is deployed away from the user, connects to each edge server, and is in a central location. For example, in an area scope, a plurality of edge servers and a central server can be arranged, and each edge server is connected with the central server; the edge server provides a path for the user to enter the network and communicates with the central server, and usually the edge server can perform a single service function or a few service functions, while the central server can perform multiple services or all service functions.

Referring to fig. 5, another embodiment of a method for sending a message in the present embodiment is shown.

Step 501, the terminal initiates a start connection (on-boot connection) to the CF, and connects with the CF.

Step 502, the CF authorizes the terminal to use the car networking service and sends communication parameters (including but not limited to radio resources, authorized V2X services, IP address of the central server, etc.) to the terminal.

Step 503, the terminal connects with the central server according to the IP address of the central server, and reports the ID of the terminal and the device type of the terminal to the central server.
