This application claims the priority of a Chinese patent application filed on July 26, 2018 with the State Intellectual Property Office of China, with the application number 201810834800.1, and the application name being "a communication method, device, and device based on the Internet of Vehicles". Incorporated by reference in this application.

Technical field

The present application relates to the field of communications, and in particular, to a communication method, device, and device based on Internet of Vehicles.

Background technique

With the development of vehicle technology and Internet technology, vehicle to vehicle (v2x) technology has gradually become a hot spot for the development of new vehicle technologies. The so-called Internet of Vehicles refers to the inter-vehicle network, inter-vehicle network and in-vehicle mobile Internet as the basis, and in accordance with agreed communication protocols and data interaction standards, between vehicles and other subjects, such as vehicles and vehicles, vehicles and base stations A large system network for wireless communication and information exchange between vehicles and between vehicles and highway equipment. It can be understood that, for wireless communication and information exchange between the vehicle and other subjects, direct communication can be used, for example, the vehicle directly communicates with highway equipment; indirect communication can also be used, for example, the vehicle communicates with the base station through a base station. Highway equipment for communication. In this application, the communication between the vehicle and other subjects is referred to as vehicle neighborhood communication (Proximity Communication, ProSe Communication). It can be understood that in order to realize the vehicle neighbor communication, the vehicle neighbor communication parameters must be pre-configured according to the corresponding standards, so that the vehicle realizes the vehicle neighbor communication according to the configured vehicle neighbor communication parameters.

At present, the 3rd Generation Partnership Project (3GPP) of the standardization organization defines that the device (hereinafter referred to as VCF) that can implement vehicle networking control functions (VCF) can send vehicle neighbor communication parameters to vehicles. User equipment (vehicle, user equipment, VUE), which configures the vehicle neighbor communication parameters in the vehicle user equipment. The vehicle neighborhood communication parameters can also be sent to the vehicle user equipment through a vehicle networking application server (VAS), and the vehicle neighborhood communication parameters can be configured in the vehicle user equipment. In other words, both VCF and VAS can send vehicle neighbor communication parameters to vehicle user equipment, so as to configure the vehicle neighbor communication parameters.

3GPP also stipulates that the priority of VCF for the configuration of vehicle neighbor communication parameters is higher than the priority of VAS for the configuration of vehicle neighbor communication parameters. That is, if the vehicle user equipment has been configured with the vehicle neighbor communication parameters from the VCF, the vehicle neighbor communication parameters from the VAS cannot be configured.

However, in some scenarios, the VAS needs to take the initiative to control the configuration of vehicle neighbor communication parameters, that is, the user equipment of the vehicle needs to configure the vehicle neighbor communication parameters from the VAS. The current vehicle neighbor communication parameter configuration mechanism cannot achieve this purpose.

Summary of the Invention

The embodiments of the present application provide a communication method, device, and device based on Internet of Vehicles, so that the VAS can configure vehicle neighbor communication parameters.

Further, according to the parameter configuration policy and the configuration parameters carried in the parameter configuration instruction, the vehicle neighbor communication parameters are determined. Carry out modification and implement vehicle neighbor communication according to the modified vehicle neighbor communication parameters. It can be seen that even if the vehicle user equipment has been configured with the vehicle neighbor communication parameters from the VCF, the vehicle networking application server VAS can send the vehicle user equipment to modify the vehicle neighbor according to the parameter configuration instruction.

In a possible implementation manner of the embodiment of the present application, the parameter configuration strategy may include all replacements. The so-called all replacements refer to replacing all vehicle neighboring communication parameters with configuration parameters in a parameter configuration instruction. If the parameter configuration strategy is to replace all, all the vehicle neighbor communication parameters can be replaced by the configuration parameters carried in the parameter configuration instruction. Specifically, all the vehicle neighbor communication parameters can be deleted, and the configuration parameters carried in the parameter configuration instruction can be used as modified parameters to achieve all replacements of the neighbor communication parameters.

If the parameter configuration strategy is parameter increase, the vehicle neighbor communication parameters and configuration parameters can be used as modified parameters. This is to increase the configuration parameters carried in the parameter configuration instruction on the basis of retaining the vehicle's neighbor communication parameters.

In a possible implementation manner of the embodiment of the present application, the vehicle neighborhood communication parameter may be, for example, a neighborhood communication fifth interface parameter (PC5) parameter (hereinafter referred to as a PC5 parameter).

In a possible implementation manner of the embodiment of the present application, considering that the control range of the Internet of Vehicles application server is limited, within the control range of the Internet of Vehicles application server, the vehicle user equipment configures the instruction according to the parameters sent by the Internet of Vehicles application server. After the modification of the vehicle neighbor communication parameters is completed, the vehicle neighbor communication can be implemented within the control range of the vehicle networking control server according to the modified parameters. Once the vehicle drives out of the control range of the IoV application server, according to the parameters obtained by the modification, the vehicle may not be able to communicate with other devices in the vicinity of the vehicle. In view of this, before performing the step of configuring the vehicle neighbor communication parameters according to the configuration parameters and the parameter configuration strategy corresponding to the configuration type identifier, the vehicle neighbor communication parameters may also be saved. In order to facilitate vehicle neighborhood communication according to the vehicle neighborhood communication parameters when the vehicle is out of the control range of the vehicle networking application server.

detailed description

The embodiments of the present application provide a communication method, device, and device based on the Internet of Vehicles, which can solve the current vehicle user equipment has been configured with the vehicle neighbor communication parameters from the VCF, so the vehicle user equipment cannot be configured with the vehicle neighbor communication parameters from the VAS. The problem is that the vehicle user equipment can also configure the vehicle neighbor communication parameters from the VAS when the vehicle neighbor communication parameters from the VCF have been configured.

The terms "first", "second", "third", "fourth", and the like (if present) in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and need not be used For describing a particular order or sequence. It should be understood that the data used in this way are interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than what is illustrated or described herein. Furthermore, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or device that includes a series of steps or units need not be limited to those explicitly listed Those steps or units may instead include other steps or units not explicitly listed or inherent to these processes, methods, products or equipment.

Currently, 3GPP defines that vehicle neighborhood communication parameters can be sent to vehicle user equipment through VCF, and vehicle neighborhood communication parameters can be configured in the vehicle user equipment. The vehicle neighbor communication parameters can also be sent to the vehicle user equipment through the VAS, and the vehicle neighbor communication parameters can be configured on the vehicle user equipment. In other words, both VCF and VAS can send vehicle neighbor communication parameters to vehicle user equipment, so as to configure the vehicle neighbor communication parameters.

It can be understood in conjunction with FIG. 1, which is a schematic diagram of an exemplary application scenario provided by an embodiment of the present application.

The figure shows a specific way in which the VCF and VAS send vehicle neighbor communication parameters to the VUE.

Specifically, the VCF 110 can directly send the vehicle neighbor communication parameters to the VUE 120 through the V3 interface.

The V3 interface is an interface between VUE 110 and VCF 110 in a public land mobile network (PLMN) to which VUE 120 belongs.

VAS 130 can send vehicle neighbor communication parameters to VUE 120 in two ways.

The first method: VAS 130 can directly send vehicle neighbor communication parameters to VUE 120 through the V1 interface.

Among them, V1 interface is the interface between VAS 130 and the application built in VUE 120.

The second method: VAS 130 sends the vehicle neighbor communication parameters to VCF 110 through the V2 interface, and negotiates with VCF 110. Finally, VCF 110 sends the negotiated vehicle neighbor communication parameters to VUE 120 through the V3 interface.

Among them, the V2 interface is the interface between VCF 110 and VAS 130.

It can be understood that, for the first method, if the VUE has configured the vehicle neighbor communication parameters from the VCF, the VUE cannot configure the vehicle neighbor communication parameters from the VAS.

For the second method, since the vehicle neighbor communication parameters configured by the VUE are the vehicle neighbor communication parameters after the VAS and VCF negotiate, in fact, it is equivalent to the VUE configured with the vehicle neighbor communication parameters from the VAS.

However, in practical applications, generally speaking, VCF is usually attributed to the operator, while VAS may be attributed to road affairs, automobile companies, traffic police or government departments. In other words, there may not be a V2 interface between VCF and VAS, that is, the VUE cannot configure the vehicle neighbor communication parameters after the VAS negotiates with VCF.

It can be understood that, in some scenarios in practical applications, vehicle user equipment needs to configure vehicle neighbor communication parameters from the VAS. For example, when a vehicle enters the VAS control range of an intersection, the vehicle user equipment needs to configure the vehicle neighborhood communication parameters from the VAS at the intersection to implement vehicle neighborhood communication. Another example is that the highway belongs to the management category of the Ministry of Transport. When a vehicle enters the highway, it means that the vehicle has entered the VAS control range of the Ministry of Transport. The user equipment of the vehicle must be configured with the VAS vehicle neighbor communication from the Ministry of Transport. Parameters to achieve vehicle neighbor communication. In this case, since there may be no V2 interface between VCF and VAS, the vehicle user equipment cannot adopt the above second method to configure the vehicle neighbor communication parameters from the VAS. The vehicle user equipment can only use the above first method to configure the vehicle neighbor communication parameters from the VAS. However, with the first configuration method, if the vehicle user equipment has been configured with the vehicle neighborhood communication parameters from the VCF, the vehicle user equipment cannot configure the vehicle neighborhood communication parameters from the VAS.

In view of this, the embodiments of the present application provide a communication method, device, and device based on the Internet of Vehicles, which can solve the current vehicle user equipment has been configured with the vehicle neighborhood communication parameters from the VCF, so the vehicle user equipment cannot configure the vehicle from the VAS The problem of the neighbor communication parameters, so that the vehicle user equipment can configure the vehicle neighbor communication parameters from the VAS even if the vehicle neighbor communication parameters from the VCF have been configured.

Referring to FIG. 2, which is a schematic flowchart of a communication method based on a vehicle networking provided by an embodiment of the present application.

The communication method provided in the embodiments of the present application is described in detail below.

It should be noted that the communication method provided in the embodiments of the present application may be applied to a user equipment of a vehicle.

The vehicle user equipment mentioned in the embodiments of the present application refers to user equipment located on a vehicle. The embodiment of the present application does not specifically limit vehicle user equipment, and the vehicle user equipment may be, for example, a terminal device such as a vehicle-mounted computer.

The method may be implemented through steps 201 to 203.

Step 201: Obtain a parameter configuration instruction sent by a connected vehicle application server. The parameter configuration instruction carries a configuration type identifier and a configuration parameter for configuring a vehicle's neighbor communication parameters. The configuration type identifier is used to indicate a parameter configuration strategy.

It should be noted that the vehicle neighbor communication parameters mentioned in the embodiments of the present application refer to parameters that need to be configured to implement vehicle neighbor communication. This embodiment of the present application does not specifically limit which parameter the vehicle neighbor communication parameter is. As an example, the vehicle neighbor communication parameter may be, for example, a fifth communication parameter (PC5) parameter (hereinafter referred to as a PC5 parameter).

It can be understood that the vehicle neighbor communication parameters may include multiple parameters. Taking the PC5 parameter as an example, the PC5 parameter may include parameters such as an authorized service identifier, a wireless communication frequency band, an authorized operator network, and a parameter validity period. That is to say, when configuring the vehicle neighbor communication parameters, multiple parameters can be configured at the same time. Therefore, in a possible implementation manner of the embodiment of the present application, the configuration parameters in the parameter configuration instruction may be parameter identifiers and parameter values. The forms appear in pairs. The parameter identifier is used to identify a specific vehicle neighbor communication parameter, and the parameter value is used to indicate a specific value of the specific vehicle neighbor communication parameter.

It can be understood that the vehicle user equipment and the vehicle networking application server can communicate through the network. Therefore, the vehicle networking application server can send parameter configuration instructions to the vehicle user equipment through the network, that is, the vehicle user equipment can use the network to obtain the vehicle networking. Parameter configuration instructions sent by the application server.

This embodiment of the present application does not specifically limit the configuration type identifier. As an example, the configuration type identifier may be represented by an 8-bit binary number. For example, the configuration type identifier can be 01H.

It should be noted that the embodiment of the present application does not specifically limit the parameter configuration strategy. As an example, the parameter configuration strategy may include: full replacement, partial replacement, parameter addition, and parameter maintenance.

Among them, the so-called full replacement refers to replacing all the vehicle neighboring communication parameters with the configuration parameters in the parameter configuration instruction. The so-called partial replacement refers to modifying the value of the vehicle neighbor communication parameter corresponding to the configuration parameter to the value of the configuration parameter. The so-called partial increase refers to retaining the vehicle neighbor communication parameters and increasing the configuration parameters in the parameter configuration instruction. The so-called parameter maintenance means that the vehicle's neighbor communication parameters are retained without any modification.

It should be noted that the configuration type identifier in the embodiment of the present application has a corresponding relationship with the parameter configuration strategy. According to the configuration type identifier, a parameter configuration policy corresponding to the configuration type identifier can be determined. The corresponding relationship between the configuration type identifier and the parameter configuration policy may be, for example, the relationship shown in Table 1 below.

Table 1

配置类型标识Configuration type identification	参数配置策略Parameter configuration strategy
01H01H	全部替换Replace all
11H11H	部分替换Partial replacement
10H10H	参数增加Parameter increase
00H00H	参数维持Parameter maintenance

It should be noted that Table 1 is only a schematic description and does not constitute a limitation on the embodiments of the present application. The configuration type identifiers in the embodiments of the present application are not limited to those shown in Table 1. The parameter configuration strategies in the embodiments of the present application It is not limited to the content shown in Table 1, and the corresponding relationship between the configuration type identifier and the parameter configuration policy is not limited to the corresponding relationship shown in Table 1. For example, when the configuration type identifier in the parameter configuration instruction is empty, the corresponding parameter configuration policy is “parameter maintenance”.

Step 202: Modify the vehicle neighbor communication parameters according to the configuration parameters and the parameter configuration strategy corresponding to the configuration type identifier.

As mentioned above, the parameter configuration strategy may include full replacement, partial replacement, parameter increase, and parameter maintenance. For these four parameter configuration strategies, specific implementation methods for modifying the vehicle's neighbor communication parameters are introduced below.

If the parameter configuration strategy is to replace all, the vehicle neighborhood communication parameters are modified according to the configuration parameters and the parameter configuration strategy corresponding to the configuration type identifier. In specific implementation, all vehicle neighborhood communication parameters may be replaced by the configuration carried in the parameter configuration instruction. parameter. Specifically, all the vehicle neighbor communication parameters may be deleted, and the configuration parameters carried in the parameter configuration instruction may be used as the modified parameters.

If the parameter configuration strategy is a partial replacement, modify the vehicle neighbor communication parameters according to the configuration parameters and the parameter configuration strategy corresponding to the configuration type identifier. In specific implementation, the value of the vehicle neighbor communication parameters corresponding to the configuration parameters can be modified to The value of the configuration parameter. As mentioned above, the configuration parameters in the parameter configuration instruction may appear in pairs in the form of a parameter identifier and a parameter value. Therefore, the value of the vehicle neighbor communication parameter corresponding to the configuration parameter is modified to the value of the configuration parameter. In specific implementation, the parameter identifier in the configuration parameter can be determined first, and the parameter value corresponding to the parameter identifier in the vehicle neighbor communication parameter is replaced. This parameter identifies the corresponding parameter value in the configuration parameter.

For example, the configuration parameter includes two pairs of parameter identifiers and parameter values. Specifically, it can be understood in conjunction with Table 2 below.

Table 2

参数标识Parameter identification	参数parameter	参数值Parameter value
0AH0AH	无线通信频段Wireless communication band	2.4GHz2.4GHz
0BH0BH	授权的业务标识Authorized business identity	AAHAAH

Regarding Table 2, it should be noted that the vehicle networking application server wishes to modify the value of the radio communication frequency band in the vehicle's neighbor communication parameters to 2.4 GHz, and modify the authorized service identifier to AAH. After the vehicle user equipment receives the parameter configuration instruction, according to the parameter identification 0AH in the configuration parameter in the parameter configuration instruction, it is determined that the parameter to be replaced is the wireless communication frequency band, thereby replacing the value of the wireless communication frequency band parameter in the vehicle neighbor communication parameter with 2.4. GHz. Similarly, according to the parameter identifier 0BH in the configuration parameter in the parameter configuration instruction, it is determined that the parameter to be replaced is an authorized service identifier, thereby replacing the value of the authorized service identifier parameter in the vehicle neighborhood communication parameter with AAH.

If the parameter configuration strategy is parameter increase, the vehicle neighborhood communication parameters are modified according to the configuration parameters and the parameter configuration strategy corresponding to the configuration type identifier. In specific implementation, the vehicle neighborhood communication parameters and configuration parameters may be used as modified parameters. That is, when the parameter configuration strategy is parameter increase, the configuration parameters carried in the parameter configuration instruction are added on the basis of retaining the vehicle neighbor communication parameters.

If the parameter configuration strategy is parameter maintenance, the vehicle neighborhood communication parameters are modified according to the configuration parameters and the parameter configuration strategy corresponding to the configuration type identifier. In specific implementation, the vehicle neighborhood communication parameters can be retained without any modification.

It should be noted that, in practical applications, when the vehicle networking application server configures vehicle neighbor communication parameters, more parameters may need to be modified. At this time, all replacement strategies may be adopted. However, it is also possible to modify some parameters and increase some parameters at the same time. At this time, it is necessary to adopt both a partial replacement strategy and a parameter increase strategy. In other words, the vehicle networking application server may use only one parameter configuration strategy when configuring the vehicle neighbor communication parameters, or may use multiple parameter configuration strategies.

When one of the parameter configuration strategies is adopted, the parameter configuration instruction may be in the form shown in FIG. 3. That is, the format of "first configuration type identifier + first configuration parameter" is used.

The vehicle user equipment may modify the vehicle neighbor communication parameters according to the first configuration parameter and a parameter configuration policy corresponding to the first configuration type identifier.

When using a variety of parameter configuration strategies, there are multiple possible implementations. Here are two possible implementations.

The first implementation manner: the vehicle networking application server sends two parameter configuration instructions to the vehicle user equipment, one parameter configuration instruction corresponds to the second parameter configuration policy, and the other parameter configuration instruction corresponds to the third parameter configuration policy. The format of these two parameter configuration instructions can be in the form shown in Figure 3. I won't repeat them here.

The second implementation manner: The vehicle networking application server sends only one parameter configuration instruction to the vehicle user equipment, and the parameter configuration instruction may be in the form described in FIG. 4. That is, in the form of "the second configuration type identifier + the second configuration parameter + the third configuration type identifier + the third configuration parameter", the vehicle user equipment can configure a policy pair according to the second configuration parameter and the parameter corresponding to the second configuration type identifier. The vehicle neighbor communication parameters are modified, and the vehicle neighbor communication parameters are modified according to the third configuration parameter and a parameter configuration policy corresponding to the third configuration type identifier.

It should be noted that FIG. 3 and FIG. 4 are only schematic illustrations, and cannot constitute a limitation on the embodiments of the present application.

Step 203: Implement the vehicle neighbor communication according to the modified vehicle neighbor communication parameters.

It can be understood that after the modification of the vehicle neighbor communication parameters is completed according to the parameter configuration instruction sent by the vehicle networking application server, the vehicle neighbor communication can be implemented by using the modified parameters.

By using the communication method provided in the embodiment of the present application, first, a vehicle user equipment obtains a parameter configuration instruction sent by a vehicle networking application server, and the parameter configuration instruction carries a configuration type identifier and a configuration parameter for configuring a vehicle neighbor communication parameter, and different configurations The type identifier corresponds to different parameter configuration strategies; that is, after the vehicle user equipment obtains the parameter configuration instruction, it can parse the parameter configuration instruction, determine the configuration type identifier in the parameter configuration instruction, and determine according to the configuration type identifier. The parameter configuration strategy of the vehicle neighborhood communication parameters is further modified according to the parameter configuration strategy and the configuration parameters carried in the parameter configuration instruction, and the vehicle neighborhood communication is implemented according to the modified parameters. It can be seen that even if the vehicle user equipment has been configured with the vehicle neighbor communication parameters from the VCF, the vehicle networking application server VAS can send a parameter configuration instruction to the user equipment to enable the vehicle user equipment to modify the vehicle neighbor communication parameters according to the parameter configuration instruction. In order to achieve the purpose of vehicle user equipment to configure vehicle neighbor communication parameters from VAS.

As mentioned above, the connected car application server may belong to road administration, car companies, traffic police or government departments. That is to say, the control range of the Internet of Vehicles application server is limited. Within the control range of the Internet of Vehicles application server, the vehicle user equipment can modify the vehicle communication parameters according to the parameter configuration instructions sent by the Internet of Vehicles application server. According to the modified parameters, the vehicle's neighbor communication is realized within the control range of the vehicle networking control server. Once the vehicle drives out of the control range of the IoV application server, according to the parameters obtained by the modification, the vehicle may not be able to communicate with other devices in the vicinity of the vehicle. In view of this, in a possible implementation manner of the embodiment of the present application, before performing step 202: configuring the vehicle neighbor communication parameters according to the configuration parameters and the parameter configuration policy corresponding to the configuration type identifier, the vehicle may also be saved. Neighbor communication parameters. In order to facilitate vehicle neighborhood communication according to the vehicle neighborhood communication parameters when the vehicle is out of the control range of the vehicle networking application server.

It should be noted that during the driving process of the vehicle, it can be determined in real time whether the vehicle is out of the control range of the Internet of Vehicles application server. Once the vehicle is out of the control range of the Internet of Vehicles application server, the vehicle neighborhood communication is realized according to the previously saved vehicle neighborhood communication parameters.

The embodiments of the present application do not specifically limit the specific implementation manners for determining whether the vehicle is out of the control range of the IoV application server. The following describes two possible specific implementation manners for determining whether the vehicle is out of the control range of the IoV application server.

In a possible implementation manner, if the vehicle user equipment cannot establish a connection with the IoV application server, the vehicle may be considered to be out of the control range of the IoV application server.

In another possible implementation manner, since the connected vehicle application server generally has a corresponding control range identifier, the corresponding control range may be determined according to the control range identifier. Therefore, according to the location of the vehicle and the control range of the connected vehicle application server, it can be determined whether the vehicle is out of the control range of the connected vehicle application server.

The communication method provided by the embodiment of the present application has been described above, and the communication method provided by the embodiment of the present application is described below with reference to specific scenarios.

Refer to FIG. 5, which is a schematic diagram of an application scenario provided by an embodiment of the present application. In this scenario, the vehicle first travels in the first area 510 of the VCF control range, and then the vehicle enters the VAS control range 520. After driving for a period of time in the VAS control range 520, the vehicle leaves the VAS control range 520 and continues. Drive in the second area 530 of the VCF control range.

Referring to FIG. 6, which is a schematic flowchart of a communication method according to an embodiment of the present application.

This method can be implemented by, for example, the following steps 601 to 606.

Step 601: Obtain a parameter configuration instruction sent by the VAS, where the parameter configuration instruction carries a configuration type identifier and a configuration parameter for configuring a vehicle neighbor communication parameter.

It can be understood that when the vehicle is traveling in the first area 310, the vehicle neighbor communication can be implemented according to the vehicle neighbor communication parameters from the VCF. When the vehicle enters the control range 520 of the VAS, step 601 may be performed.

For convenience of description, the vehicle neighbor communication parameters configured by the VCF are hereinafter referred to as initial vehicle neighbor communication parameters.

Step 602: Parse the parameter configuration instruction to obtain a configuration type identifier and a configuration parameter.

Step 603: Save the initial vehicle neighbor communication parameters.

It should be noted that the embodiment of this application does not limit the execution order of step 603, and step 603 only needs to be executed before step 604. However, in general, step S603 is performed between steps S602 and S604. That is, after the configuration type identifier and the configuration parameters are determined, the modification is performed before the vehicle neighbor communication parameters are modified.

Step 604: Modify the vehicle neighbor communication parameters according to the configuration parameters and the parameter configuration strategy corresponding to the configuration type identifier.

Step 605: Car neighbor communication is implemented according to the modified parameters.

Step 606: It is determined that the vehicle has left the VAS control range according to the area range identifier of the VAS and the position of the vehicle, and the vehicle neighbor communication is implemented according to the saved initial vehicle neighbor communication parameters.
