Description

Communication method, device and equipment based on Internet of vehicles
Technical Field
The application relates to the field of communication, in particular to a communication method, device and equipment based on Internet of vehicles.
Background
With the development of vehicle technology and internet technology, vehicle to electronic (v 2x) technology is becoming a hot spot for the development of new vehicle technology. The internet of vehicles refers to a large system network that performs wireless communication and information exchange between vehicles and other subjects, such as between vehicles, between vehicles and base stations, and between vehicles and road equipment, according to an agreed communication protocol and data interaction standard based on an in-vehicle network, an inter-vehicle network, and a vehicle-mounted mobile internet. It will be appreciated that the wireless communication and information exchange between the vehicle and the other subject may be by way of direct communication, for example, the vehicle communicates directly with the road equipment; indirect communication may also be used, for example, where the vehicle communicates with the road equipment via a base station. In the present application, Communication between a vehicle and another subject directly is referred to as proximity service Communication (ProSe Communication). It is to be understood that to implement the vehicle proximity communication, the vehicle proximity communication parameters are pre-configured following the corresponding standards, so that the vehicle implements the vehicle proximity communication according to the configured vehicle proximity communication parameters.
Currently, the 3rd generation partnership project (3 GPP) defines that vehicle proximity communication parameters can be configured in a Vehicle User Equipment (VUE) by a device (hereinafter, VCF) implementing a vehicle to electrical networking control function (VCF) transmitting the vehicle proximity communication parameters to the VUE. The vehicle neighbor communication parameters may also be sent to the vehicle user equipment through a vehicle to electrical application server (VAS), and the vehicle neighbor communication parameters are configured in the vehicle user equipment. That is, both the VCF and the VAS may send the vehicle proximity communication parameters to the vehicle user device, thereby enabling configuration of the vehicle proximity communication parameters.
The 3GPP also specifies that VCF prioritizes vehicle-neighbor communication parameter configuration over VAS. That is, if the vehicular user device has configured vehicular neighbor communication parameters from the VCF, then vehicular neighbor communication parameters from the VAS cannot be configured.
However, in some scenarios, the VAS needs to master the initiative for configuring the vehicle neighbor communication parameters, that is, the vehicle user equipment needs to configure the vehicle neighbor communication parameters from the VAS, and the current configuration mechanism of the vehicle neighbor communication parameters cannot achieve this purpose.
Disclosure of Invention
The embodiment of the application provides a communication method, a device and equipment based on Internet of vehicles, so that a VAS can configure vehicle neighbor communication parameters.
In a first aspect of the embodiments of the present application, a communication method is provided, which may be applied to a vehicle user equipment, where after the vehicle user equipment obtains a parameter configuration instruction sent by a car networking application server, the parameter configuration instruction may be analyzed, a configuration type identifier in the parameter configuration instruction is obtained, a parameter configuration policy for a vehicle neighbor communication parameter is determined according to the configuration type identifier, and further, the vehicle neighbor communication parameter is modified according to the parameter configuration policy and a configuration parameter carried in the parameter configuration instruction, and vehicle neighbor communication is implemented according to the modified vehicle neighbor communication parameter. Therefore, even if the vehicle user equipment has configured the vehicle neighbor communication parameters from the VCF, the vehicle networking application server VAS may cause the vehicle user equipment to modify the vehicle neighbor communication parameters according to the parameter configuration instruction by sending the vehicle user equipment the form of the parameter configuration instruction, so as to achieve the purpose that the vehicle user equipment configures the vehicle neighbor communication parameters from the VAS.
In a possible implementation manner of the embodiment of the present application, the parameter configuration policy may include total replacement, where the total replacement refers to total replacement of the vehicle neighbor communication parameters by the configuration parameters in the parameter configuration instruction. If the parameter configuration strategy is complete replacement, all the vehicle neighbor communication parameters can be replaced by the configuration parameters carried in the parameter configuration instruction. Specifically, all the neighbor communication parameters of the vehicle may be deleted, and the configuration parameters carried in the parameter configuration instruction are used as the modified parameters, so as to implement all the replacement of the neighbor communication parameters.
In a possible implementation manner of the embodiment of the present application, the parameter configuration policy may include partial replacement, where the partial replacement is to modify a value of a vehicle neighbor communication parameter corresponding to a configuration parameter to a value of the configuration parameter. If the parameter configuration strategy is partial replacement, the value of the vehicle neighbor communication parameter corresponding to the configuration parameter can be modified into the value of the configuration parameter. So as to retain part of the original neighbor communication parameters and modify part of the neighbor communication parameters.
In a possible implementation manner of the embodiment of the present application, the parameter configuration policy may include a parameter increase, so-called a partial increase, that is, reserving the vehicle neighbor communication parameters, and increasing the configuration parameters in the parameter configuration instruction. If the parameter configuration strategy is parameter increase, the vehicle neighbor communication parameters and the configuration parameters can be used as modified parameters. The configuration parameters carried in the parameter configuration instruction are increased on the basis of keeping the vehicle neighbor communication parameters.
In a possible implementation manner of the embodiment of the present application, the vehicle neighbor communication parameter may be, for example, a proximity service communication 5 (PC 5) 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 car networking application server is limited, in the control range of the car networking application server, after the vehicle user equipment completes modification of the vehicle neighbor communication parameters according to the parameter configuration instruction sent by the car networking application server, the vehicle neighbor communication can be realized in the control range of the car networking control server according to the parameters obtained through the modification. Once the vehicle is driven out of the control range of the internet of vehicles application server, the vehicle may not be able to achieve vehicle proximity communication with other devices according to the modified parameters. In view of this, before the performing step configures the vehicle neighbor communication parameters according to the configuration parameters and the parameter configuration policy corresponding to the configuration type identifier, the vehicle neighbor communication parameters may also be saved. When the vehicle is out of the control range of the Internet of vehicles application server, the vehicle neighbor communication is realized according to the vehicle neighbor communication parameters.
In a possible implementation manner of the embodiment of the application, in the driving process of the vehicle, whether the vehicle is separated from the control range of the internet of vehicles application server can be judged in real time, and once the vehicle is separated from the control range of the internet of vehicles application server, the vehicle neighbor communication is realized according to the vehicle neighbor communication parameters saved previously.

Detailed Description
The embodiment of the application provides a communication method, a device and equipment based on the Internet of vehicles, which can solve the problem that vehicle user equipment cannot configure vehicle neighbor communication parameters from a VAS when the vehicle user equipment configures the vehicle neighbor communication parameters from a VCF at present, so that the vehicle user equipment can also configure the vehicle neighbor communication parameters from the VAS under the condition that the vehicle user equipment configures the vehicle neighbor communication parameters from the VCF.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Currently, 3GPP defines that vehicular neighbor communication parameters can be sent to a vehicular user equipment through a VCF, where they are configured. The vehicle proximity communication parameters may also be sent to the vehicle user equipment via the VAS, where the vehicle proximity communication parameters are configured. That is, both the VCF and the VAS may send the vehicle proximity communication parameters to the vehicle user device, thereby enabling configuration of the vehicle proximity communication parameters.
As can be understood in conjunction with fig. 1, this figure is a schematic diagram of an exemplary application scenario provided in the embodiments of the present application.
The figure illustrates a specific way in which the VCF and VAS send vehicle proximity communication parameters to the VUE.
Specifically, the VCF110 may send the vehicle proximity communication parameters directly to the VUE 120 over the V3 interface.
The V3 interface is an interface between the VUE 120 and the VCF110 in a Public Land Mobile Network (PLMN) to which the VUE 120 belongs.
The VAS 130 can send the vehicle proximity communication parameters to the VUE 120 in two ways.
The first mode is as follows: the VAS 130 can send vehicle proximity communication parameters directly to the VUE 120 over the V1 interface.
Among them, the V1 interface is an interface between the VAS 130 and applications built in the VUE 120.
The second mode is as follows: the VAS 130 sends the vehicle proximity communication parameters to the VCF110 via the V2 interface, negotiates with the VCF110, and finally sends the negotiated vehicle proximity communication parameters to the VUE 120 via the V3 interface by the VCF 110.
Wherein the V2 interface is an interface between VCF110 and VAS 130.
It can be appreciated that for the first approach, if the VUE has configured vehicle proximity communication parameters from the VCF, the VUE cannot configure vehicle proximity communication parameters from the VAS.
With respect to the second approach, since the VUE configured vehicular-neighbor communication parameters are vehicular-neighbor communication parameters after the VAS negotiates with the VCF, in fact, it is equivalent to the VUE configuring vehicular-neighbor communication parameters from the VAS.
However, in practical applications, generally, the VCF is usually assigned to the operator, and the VAS may be assigned to road administration, vehicle and enterprise, traffic police, or government departments, etc. That is, there may not be a V2 interface between the VCF and the VAS, i.e., the VUE may not be able to configure vehicle neighbor communication parameters after the VAS negotiates with the VCF.
It will be appreciated that in some scenarios in practical applications, the vehicle user device needs to configure vehicle proximity communication parameters from the VAS. For example, when a vehicle enters the VAS control range of an intersection, the vehicle user device configures vehicle proximity communication parameters from the VAS of the intersection to enable vehicle proximity communication. For another example, the highway belongs to the management category of the transportation unit, and when the vehicle enters the highway, the vehicle user equipment configures vehicle proximity communication parameters of the VAS from the transportation unit to realize vehicle proximity communication, which indicates that the vehicle enters the VAS control range of the transportation unit. For this case, the vehicle user device cannot configure the vehicle proximity communication parameters from the VAS in the second way above, since there may be no V2 interface between the VCF and the VAS. The vehicle user equipment can only implement the configuration of the vehicle proximity communication parameters from the VAS in the first way above. However, with the first configuration, if the vehicle user equipment has already configured the vehicle neighbor communication parameters from the VCF, the vehicle user equipment cannot configure the vehicle neighbor communication parameters from the VAS for performing the vehicle neighbor communication.
In view of this, embodiments of the present application provide a communication method, apparatus, and device based on internet of vehicles, which can solve the problem that, when a current vehicle user equipment has configured a vehicle neighbor communication parameter from a VCF, the vehicle user equipment cannot configure the vehicle neighbor communication parameter from a VAS, so that even if the vehicle user equipment has configured the vehicle neighbor communication parameter from the VCF, the vehicle user equipment can also configure the vehicle neighbor communication parameter from the VAS.
Referring to fig. 2, the figure is a schematic flowchart of a communication method based on internet of vehicles according to an embodiment of the present application.
The following describes the communication method provided in the embodiments of the present application in detail.
It should be noted that the communication method provided in the embodiment of the present application may be applied to a vehicle user equipment.
The vehicle user equipment mentioned in the embodiments of the present application refers to user equipment located on a vehicle. The embodiment of the application does not specifically limit the vehicle user equipment, and the vehicle user equipment may be terminal equipment such as a vehicle-mounted computer.
The method may be implemented by steps 201 to 203.
Step 201: the method comprises the steps of obtaining a parameter configuration instruction sent by a vehicle networking application server, wherein the parameter configuration instruction carries a configuration type identifier and a configuration parameter for configuring vehicle neighbor communication parameters, and the configuration type identifier is used for indicating a parameter configuration strategy.
It should be noted that the vehicle proximity communication parameter mentioned in the embodiment of the present application refers to a parameter that needs to be configured to implement vehicle proximity communication. The embodiment of the present application does not specifically define which parameter the vehicle neighbor communication parameter is, and as an example, the vehicle neighbor communication parameter may be, for example, a proximity service communication 5 (PC 5) parameter (hereinafter referred to as PC5 parameter).
It is understood that the vehicle proximity communication parameter may include a plurality of parameters, and taking the PC5 parameter as an example, the PC5 parameter may include a service identifier authorized to be used, a frequency band of wireless communication, an operator network authorized to be used, a validity period of the parameter, and the like. That is, when configuring the vehicle neighbor communication parameters, multiple parameters may be configured at the same time, and therefore, in a possible implementation manner of the embodiment of the present application, the configuration parameters in the parameter configuration instruction may be in the form of a pair of a parameter identifier and a parameter value. Wherein the parameter identification is used for identifying a specific vehicle neighbor communication parameter, and the parameter value is used for representing 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 may communicate with each other through a network, and therefore, the vehicle networking application server may send the parameter configuration instruction to the vehicle user equipment through the network, that is, the vehicle user equipment may obtain the parameter configuration instruction sent by the vehicle networking application server through the network.
The embodiment of the present application is not particularly limited to the configuration type identifier, and as an example, the configuration type identifier may be represented by an 8-bit 2-ary number. For example, the configuration type identifier may be 01H.
It should be noted that, the embodiment of the present application does not specifically limit the parameter configuration policy, and as an example, the parameter configuration policy may include: full replacement, partial replacement, parameter addition, and parameter maintenance.
The total replacement means that all of the vehicle neighbor communication parameters are replaced with the configuration parameters in the parameter configuration command. The partial replacement means that the value of the vehicle-near communication parameter corresponding to the configuration parameter is modified to the value of the configuration parameter. The partial addition means that the vehicle neighbor communication parameters are retained and the configuration parameters in the parameter configuration command are added. By parameter maintenance, it is meant that the vehicle 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 policy. According to the configuration type identification, the parameter configuration strategy corresponding to the configuration type identification 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
Figure BDA0001744306810000051
Figure BDA0001744306810000061
It should be noted that table 1 is only an illustration of a schematic diagram, and does not constitute a limitation on the embodiments of the present application, the configuration type identifier in the embodiments of the present application is not limited to the content shown in table 1, the parameter configuration policy in the embodiments of the present application 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 "parameter maintenance" is used.
Step 202: and modifying the vehicle neighbor communication parameters according to the configuration parameters and the parameter configuration strategy corresponding to the configuration type identifier.
As described above, the parameter configuration policy may include full replacement, partial replacement, parameter addition, parameter maintenance, and the like. Specific implementation methods for modifying the vehicle neighbor communication parameters are respectively described below for the four parameter configuration strategies.
If the parameter configuration strategy is completely replaced, modifying the vehicle neighbor communication parameters according to the configuration parameters and the parameter configuration strategy corresponding to the configuration type identifier, and completely replacing the vehicle neighbor communication parameters with the configuration parameters carried in the parameter configuration instruction during specific implementation. Specifically, all the vehicle neighbor communication parameters may be deleted, and the configuration parameters carried in the parameter configuration instruction are used as the modified parameters.
If the parameter configuration strategy is partial replacement, the vehicle neighbor communication parameters are modified according to the configuration parameters and the parameter configuration strategy corresponding to the configuration type identifier, and the values of the vehicle neighbor communication parameters corresponding to the configuration parameters can be modified into the values of the configuration parameters during specific implementation. As mentioned above, the configuration parameters in the parameter configuration instruction may be in the form of parameter identifications and parameter values paired. Therefore, when the value of the vehicle neighbor communication parameter corresponding to the configuration parameter is modified into the value of the configuration parameter, in a specific implementation, the parameter identifier in the configuration parameter may be determined first, and the parameter value corresponding to the parameter identifier in the vehicle neighbor communication parameter is replaced with the parameter value corresponding to the parameter identifier in the configuration parameter.
For example, two pairs of parameter identifications and parameter values are included in the configuration parameters, which can be understood in detail in conjunction with table 2 below.
TABLE 2
Parameter identification Parameter(s) Parameter value
0AH Radio communication frequency band 2.4GHz
0BH Authorized service identification AAH
With respect to table 2, it should be noted that the car networking application server wants to modify the value of the radio communication frequency band in the vehicle neighbor communication parameter to 2.4GHz and modify the authorized service identification to AAH. After receiving the parameter configuration instruction, the vehicle user equipment determines that the parameter to be replaced is the wireless communication frequency band according to the parameter identifier 0AH in the configuration parameter in the parameter configuration instruction, so that the value of the wireless communication frequency band parameter in the vehicle neighbor communication parameter is replaced by 2.4 GHz. Similarly, according to the parameter identifier 0BH in the configuration parameters in the parameter configuration instruction, the parameter to be replaced is determined to be the authorized service identifier, so that the value of the authorized service identifier parameter in the vehicle neighbor communication parameter is replaced with AAH.
If the parameter configuration strategy is parameter increase, the vehicle neighbor communication parameters are modified according to the configuration parameters and the parameter configuration strategy corresponding to the configuration type identifier, and the vehicle neighbor communication parameters and the configuration parameters can be used as parameters obtained through modification during specific implementation. That is, when the parameter configuration policy is a parameter increase, the configuration parameters carried in the parameter configuration command are increased on the basis of the vehicle neighbor communication parameters.
If the parameter configuration strategy is parameter maintenance, the vehicle neighbor communication parameters are modified according to the configuration parameters and the parameter configuration strategy corresponding to the configuration type identification, and the vehicle neighbor communication parameters can be reserved without any modification during specific implementation.
It should be noted that, in practical applications, when the vehicle networking application server performs configuration of the vehicle neighbor communication parameters, there may be more parameters that need to be modified, and at this time, all alternative strategies may be adopted. However, it may be necessary to modify a portion of the parameters and add a portion of the parameters, in which case both a partial replacement strategy and a parameter addition strategy may need to be employed. That is to say, when the application server in the internet of vehicles configures the parameters of the vehicle neighbor communication, only one parameter configuration strategy may be adopted, or multiple parameter configuration strategies may be adopted.
When one of the parameter configuration policies is employed, the parameter configuration instructions may be of the form shown in FIG. 3. I.e. in the format of "first configuration type identification + first configuration parameters".
The vehicle user equipment can modify the vehicle neighbor communication parameters according to the first configuration parameters and the parameter configuration strategy corresponding to the first configuration type identifier.
When various parameter configuration policies are employed, there are many possible implementations. Two possible implementations are presented below.
The first implementation mode comprises the following steps: and the Internet of vehicles application server sends two parameter configuration instructions to the vehicle user equipment, wherein one parameter configuration instruction corresponds to a second parameter configuration strategy, and the other parameter configuration instruction corresponds to a third parameter configuration strategy. The format of these two parameter configuration instructions may take the form shown in fig. 3. And will not be described in detail herein.
The second implementation mode comprises the following steps: the car networking application server sends only one parameter configuration instruction to the vehicle user equipment, which may be of the form described in fig. 4. That is, in the form of "second configuration type identifier + second configuration parameter + third configuration type identifier + third configuration parameter", the vehicle user equipment may modify the vehicle neighbor communication parameter according to the second configuration parameter and the parameter configuration policy corresponding to the second configuration type identifier, and modify the vehicle neighbor communication parameter according to the third configuration parameter and the parameter configuration policy corresponding to the third configuration type identifier.
Fig. 3 and 4 are only schematic illustrations, and do not limit the embodiments of the present application.
Step 203: and realizing vehicle neighbor communication according to the modified vehicle neighbor communication parameters.
It can be understood that after the parameters of the vehicle neighbor communication are modified according to the parameter configuration instruction sent by the internet of vehicles application server, the vehicle neighbor communication can be realized by using the modified parameters.
The communication method provided by the embodiment of the application is utilized, firstly, the vehicle user equipment acquires a parameter configuration instruction sent by the Internet of vehicles application server, the parameter configuration instruction carries configuration type identification and configuration parameters for configuring the vehicle neighbor communication parameters, and different configuration type identifications correspond to different parameter configuration strategies; that is to say, after the vehicle user equipment acquires the parameter configuration instruction, the parameter configuration instruction may be analyzed, the configuration type identifier in the parameter configuration instruction is determined, the parameter configuration policy for the vehicle neighbor communication parameter is determined according to the configuration type identifier, further, the vehicle neighbor communication parameter is modified according to the parameter configuration policy and the configuration parameter carried in the parameter configuration instruction, and the vehicle neighbor communication is realized according to the modified parameter. Therefore, even if the vehicle user equipment has configured the vehicle neighbor communication parameter from the VCF, the vehicle networking application server VAS can make the vehicle user equipment modify the vehicle neighbor communication parameter according to the parameter configuration instruction by sending the user equipment the form of the parameter configuration instruction, so as to achieve the purpose that the vehicle user equipment configures the vehicle neighbor communication parameter from the VAS.
As previously described, the car networking application server may be owned by a road administration, car enterprise, traffic police, or government department, etc. That is to say, the control range of the car networking application server is limited, and in the control range of the car networking application server, after the vehicle user equipment completes modification of the vehicle neighbor communication parameters according to the parameter configuration instruction sent by the car networking application server, the vehicle neighbor communication can be realized in the control range of the car networking control server according to the parameters obtained through the modification. Once the vehicle is driven out of the control range of the internet of vehicles application server, the vehicle may not be able to achieve vehicle proximity communication with other devices according to the modified parameters. In view of this, in a possible implementation manner of the embodiment of the present application, in step 202: before 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 can also be saved. When the vehicle is out of the control range of the Internet of vehicles application server, the vehicle neighbor communication is realized according to the vehicle neighbor communication parameters.
It should be noted that, in the driving process of the vehicle, it may be determined in real time whether the vehicle is out of the control range of the internet of vehicles application server, and once the vehicle is out of the control range of the internet of vehicles application server, the vehicle proximity communication is implemented according to the vehicle proximity communication parameters saved before.
The embodiment of the application does not specifically limit the specific implementation manner of judging whether the vehicle is separated from the control range of the internet of vehicles application server, and two possible specific implementation manners of judging whether the vehicle is separated from the control range of the internet of vehicles application server are introduced below.
In one possible implementation, if the vehicle user device cannot establish a connection with the car networking application server, the vehicle may be considered to have left the control range of the car networking application server.
In another possible implementation manner, since the car networking application server generally has a corresponding control range identifier, the corresponding control range may be determined according to the control range identifier. Therefore, whether the vehicle is separated from the control range of the Internet of vehicles application server can be judged according to the position of the vehicle and the control range of the Internet of vehicles application server.
