Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A communication method, an apparatus, and a car networking terminal of the device-to-device D2D of the embodiments of the present invention are described below with reference to the drawings.
Fig. 1 is a flowchart of a device-to-device D2D communication method according to an embodiment of the present invention.
As shown in fig. 1, the communication method of the device-to-device D2D includes the following steps:
s101, the Internet of vehicles terminal sets the transmission cycle of the D2D resource of the Internet of vehicles terminal and the time slot position for transmitting the D2D periodic message according to the received resource configuration information.
The D2D periodic message is information that needs to be periodically sent according to the car networking function requirement, the D2D periodic message may include, but is not limited to, position information, operating state information, and the like of the vehicle, and in an actual application process, the information that is periodically sent may also be adjusted according to the car networking function requirement, which is not limited in this embodiment.
It should be understood that, in practical applications, the D2D periodicity information may be fixedly transmitted one or more times in each period, wherein the number of times the D2D periodicity information is transmitted in each period is the same as the number of slot positions.
The operating state information of the vehicle may include, but is not limited to, a vehicle speed, an acceleration, a deceleration, failure information, etc. of the vehicle.
Specifically, in the process of using the car networking terminal, the sending period of the resource of the car networking terminal D2D and the time slot position of the periodic message of the D2D sent by the car networking terminal may be set in various ways, and may be set according to the actual scene requirements, for example, as follows:
as an example, the car networking terminal may perform communication interaction with a car networking terminal having a management function (simply, a management car networking terminal), and the management car networking terminal transmits the resource configuration information, and then the car networking terminal sets a transmission period for itself to transmit the D2D resource and a slot position for transmitting the D2D periodic message according to the received resource configuration information.
In a fleet scenario, a manager in the fleet may establish a communication connection with other internet-of-vehicles terminals in the fleet through the internet-of-vehicles terminal used by the manager, display information related to the other internet-of-vehicles terminals in the fleet (e.g., name information of the internet-of-vehicles terminals) in the manager's internet-of-vehicles terminal, in order to make the operation conditions of other vehicles in the fleet be known at any time during the traveling of the fleet, and avoid the situation that the vehicles in the fleet lose contact and the members in the fleet are not aware of the situation, the manager can set the time slot position of each vehicle in the fleet for transmitting the periodic information of D2D and the transmission period of the D2D resource through the internet-of-vehicles terminal used by the manager, that is, the slot positions of each internet of vehicles terminal in the platoon for transmitting the D2D periodicity information are different, the transmission periods of each internet of vehicles terminal for transmitting the D2D resource are the same, and the set related information is transmitted to the corresponding internet of vehicles terminal in the platoon.
Wherein, it should be understood that the transmission period of the D2D resource is a time preset by the internet of vehicles communication system.
For example, the fleet has 4 vehicles in total, the four vehicle networking terminals respectively correspond to a vehicle networking terminal a, a vehicle networking terminal B, a vehicle networking terminal C and a vehicle networking terminal D, and assuming that the user of the vehicle networking terminal a is the administrator, at this time, the vehicle networking terminal a can establish communication connection with the vehicle networking terminal B, the vehicle networking terminal C and the vehicle networking terminal D, and set the corresponding slot position 1 for sending D2D periodic information and the transmission cycle of D2D resource for itself through the vehicle networking terminal a, and set the corresponding slot position 2 for sending D2D periodic information and the transmission cycle of D2D resource for the vehicle networking terminal B, set the corresponding slot position 3 for sending D2D periodic information and the transmission cycle of D2D resource for the vehicle networking terminal C, the vehicle networking terminal D sets the corresponding slot position 4 for sending D2D periodic information and the transmission cycle of D2D resource for it, therefore, each vehicle in the fleet is provided with a time slot for transmitting the D2D periodic information, and the condition that the vehicles possibly collide when transmitting the D2D periodic information is avoided. It should be understood that the manager in the fleet may send the periodic D2D information to each vehicle in the fleet, or may send the periodic D2D information to a specific vehicle in advance according to the requirement.
As another example, the network side may set the transmission period in the car networking terminal and the time slot position of transmitting the D2D periodic message.
Specifically, after the communication connection between the car networking terminal and the car networking communication system is established, the network side in the car networking communication system can set the transmission cycle for transmitting the D2D resource and the time slot position for transmitting the D2D periodic message for the currently accessed car networking terminal according to the preset resource configuration information in the car networking communication system.
S102, aiming at each sending period, when the time slot position of the D2D periodic message in the current sending period is monitored to arrive, the Internet of vehicles terminal sends the current D2D periodic message to a receiving party.
And in the time slot position of the D2D periodic message in each period, the Internet of vehicles terminal acquires the current position information and/or the current operation state information of the vehicle and sends the current position information and/or the current operation state information to the receiving party.
It should be noted that, in different application scenarios, the receiving party in this embodiment is different.
For example, in a fleet scenario, the recipient is an internet of vehicles terminal with management capabilities in the fleet.
For another example, in a common road scene, the receiver is a roadside unit arranged beside the road, and the roadside unit can send the received D2D periodic information to a traffic guidance center, so that the traffic guidance center monitors the position information of the vehicle, and when congestion in front of the vehicle is monitored, sends a congestion reminding prompt to an internet of vehicles terminal in the vehicle, so that a driver can adjust a driving route of the driver according to the prompt information.
In one embodiment of the invention, in order to enable the receiving party to identify the sending party of the information, in the process of sending the current position information and/or the current operation state information of the vehicle to the receiving party, the internet of vehicles terminal can send the identification information of the internet of vehicles terminal while sending the current position information and/or the current operation state information. The receiving party determines the sending party of the D2D periodic message through the identification information.
In one embodiment of the present invention, in order to enable the receiving party to recognize that the received message is a D2D periodic message, a type identifier may be set for the D2D periodic message, and the receiving party may recognize that the received message is a D2D periodic message through the type identifier. For example, the terminal in the internet of vehicles may set the message type header corresponding to the D2D periodic message when sending the periodic message, and the receiving party may determine that the received message includes the message type header corresponding to the D2D periodic message as the D2D periodic message when recognizing that the message type header corresponds to the periodic message.
In summary, the vehicle networking terminal of the embodiment periodically sends the D2D periodic message, so that the receiving party can determine the location information and the operating state information of the vehicle where the vehicle networking terminal is located according to the received D2D periodic message.
According to the communication method of the device-to-device D2D provided by the embodiment of the invention, the sending period of the D2D resource and the time slot position of the D2D periodic message are set according to the received resource configuration information, and the D2D periodic message is sent to the receiving party at the fixed time slot of each period, so that the vehicle networking terminal can periodically send the D2D periodic message, and the receiving party can provide reliable basis for subsequent vehicle networking services (such as vehicle early warning and vehicle fault analysis) according to the received D2D periodic message. Particularly, when the D2D periodically contains the position information and the operation state information of the vehicle, the receiving party monitors the position of the vehicle according to the position information, and timely knows the operation state of the vehicle where the terminal of the internet of vehicles is located through the operation state information.
Based on the information shown in fig. 1, when the terminal in the internet of vehicles sends D2D periodic information to the receiving party, the terminal in the internet of vehicles may also receive the location information of other vehicles sent by the sending party terminal, that is, the terminal in the internet of vehicles may also receive the location information of other vehicles, so as to perform collision warning, lane change warning, etc. according to the location information of other vehicles, or in a scene of the fleet of vehicles, the location information of other vehicles may be provided to the user, so that the user knows the location information of other vehicles in the fleet of vehicles.
Fig. 2 is a flowchart of a device-to-device D2D communication method according to another embodiment of the present invention.
As shown in fig. 2, the communication method of the device-to-device D2D includes the following steps:
s201, the Internet of vehicles terminal sets the transmission cycle of the D2D resource of the Internet of vehicles terminal and the time slot position for transmitting the D2D periodic message according to the received resource configuration information.
The D2D periodic message is information that needs to be periodically sent according to the car networking function requirement, the D2D periodic message may include, but is not limited to, position information, operating state information, and the like of the vehicle, and in an actual application process, the information that is periodically sent may also be adjusted according to the car networking function requirement, which is not limited in this embodiment.
It should be understood that, in practical applications, the D2D periodicity information may be fixedly transmitted one or more times in each period, wherein the number of times the D2D periodicity information is transmitted in each period is the same as the number of slot positions.
The operating state information of the vehicle may include, but is not limited to, a vehicle speed, an acceleration, a deceleration, failure information, etc. of the vehicle.
Specifically, in the process of using the car networking terminal, the sending period of the resource of the car networking terminal D2D and the time slot position of the periodic message of the D2D sent by the car networking terminal may be set in various ways, and may be set according to the actual scene requirements, for example, as follows:
as an example, the car networking terminal may perform communication interaction with a car networking terminal having a management function (simply, a management car networking terminal), and the management car networking terminal transmits the resource configuration information, and then the car networking terminal sets a transmission period for itself to transmit the D2D resource and a slot position for transmitting the D2D periodic message according to the received resource configuration information.
In a fleet scenario, a manager in the fleet may establish a communication connection with other internet-of-vehicles terminals in the fleet through the internet-of-vehicles terminal used by the manager, display information related to the other internet-of-vehicles terminals in the fleet (e.g., name information of the internet-of-vehicles terminals) in the manager's internet-of-vehicles terminal, in order to make the operation conditions of other vehicles in the fleet be known at any time during the traveling of the fleet, and avoid the situation that the vehicles in the fleet lose contact and the members in the fleet are not aware of the situation, the manager can set the time slot position of each vehicle in the fleet for transmitting the periodic information of D2D and the transmission period of the D2D resource through the internet-of-vehicles terminal used by the manager, that is, the slot positions of each internet of vehicles terminal in the platoon for transmitting the D2D periodicity information are different, the transmission periods of each internet of vehicles terminal for transmitting the D2D resource are the same, and the set related information is transmitted to the corresponding internet of vehicles terminal in the platoon.
Wherein, it should be understood that the transmission period of the D2D resource is a time preset by the internet of vehicles communication system.
For example, the fleet has 4 vehicles in total, the four vehicle networking terminals respectively correspond to a vehicle networking terminal a, a vehicle networking terminal B, a vehicle networking terminal C and a vehicle networking terminal D, and assuming that the user of the vehicle networking terminal a is the administrator, at this time, the vehicle networking terminal a can establish communication connection with the vehicle networking terminal B, the vehicle networking terminal C and the vehicle networking terminal D, and set the corresponding slot position 1 for sending D2D periodic information and the transmission cycle of D2D resource for itself through the vehicle networking terminal a, and set the corresponding slot position 2 for sending D2D periodic information and the transmission cycle of D2D resource for the vehicle networking terminal B, set the corresponding slot position 3 for sending D2D periodic information and the transmission cycle of D2D resource for the vehicle networking terminal C, the vehicle networking terminal D sets the corresponding slot position 4 for sending D2D periodic information and the transmission cycle of D2D resource for it, therefore, various time slots for transmitting the D2D periodic information are set for each vehicle in the fleet, and the condition that collision can be caused when the various vehicles transmit the D2D periodic information is avoided. It should be understood that the manager in the fleet may send the periodic D2D information to each vehicle in the fleet, or may send the periodic D2D information to a specific vehicle in advance according to the requirement.
As another example, the network side may set the transmission period in the car networking terminal and the time slot position of transmitting the D2D periodic message.
Specifically, after the communication connection between the car networking terminal and the car networking communication system is established, the network side in the car networking communication system can set the transmission cycle for transmitting the D2D resource and the time slot position for transmitting the D2D periodic message for the currently accessed car networking terminal according to the preset resource configuration information in the car networking communication system.
S202, aiming at each sending period, when the time slot position of the D2D periodic message in the current sending period is monitored to arrive, the Internet of vehicles terminal sends the current D2D periodic message to a receiving party.
And at the time slot position in each period, the vehicle networking terminal acquires the current position information and/or the current running state information of the vehicle and sends the current position information and/or the current running state information to a receiving party.
It should be noted that, in different application scenarios, the receiving party in this embodiment is different.
For example, in a fleet scenario, the recipient is an internet of vehicles terminal with management capabilities in the fleet.
For another example, in a common road scene, the receiver is a roadside unit arranged beside the road, and the roadside unit can send the received D2D periodic information to a traffic guidance center, so that the traffic guidance center monitors the position information of the vehicle, and when congestion in front of the vehicle is monitored, sends a congestion reminding prompt to an internet of vehicles terminal in the vehicle, so that a driver can adjust a driving route of the driver according to the prompt information.
In one embodiment of the present invention, in order to allow the receiving side to identify the sender of the information, in the process of sending the current location information and/or the current operation state information of the vehicle to the receiving side, the in-vehicle network terminal sends its own identification information while sending the current location information and/or the current operation state information. The receiving party determines the sending party of the D2D periodic message through the identification information.
In one embodiment of the present invention, in order to enable the receiving party to recognize that the received message is a D2D periodic message, a type identifier may be set for the D2D periodic message, and the receiving party may recognize that the received message is a D2D periodic message through the type identifier. For example, the terminal in the internet of vehicles may set the message type header corresponding to the D2D periodic message when sending the periodic message, and the receiving party may determine that the received message includes the message type header corresponding to the D2D periodic message as the D2D periodic message when recognizing that the message type header corresponds to the periodic message.
S203, when the vehicle networking terminal sends the non-periodic message, the vehicle networking terminal selects other time slots except the time slot used by the D2D periodic message to send the non-periodic message.
That is, in addition to transmitting the D2D periodic message to the recipient at a fixed time slot during the transmission period of the D2D resource, the vehicle networking terminal may also transmit an aperiodic message, e.g., the user may also transmit an aperiodic message through the vehicle networking terminal on demand.
The aperiodic message refers to a message that does not need to be periodically sent to the receiving party, and may include, but is not limited to, video, audio, pictures and texts, and may also include warning information.
For another example, the vehicle networking terminal may send warning information of the vehicle.
The vehicle networking terminal may transmit aperiodic messages in aperiodic message time slots in each transmission period, i.e., the vehicle networking terminal may transmit messages that do not require periodic transmission in time slots that do not require D2D periodic messages to be transmitted.
The aperiodic message time slot refers to a time slot in which the D2D periodic message does not need to be transmitted.
For example, a cycle is divided into ten slots, and if it is determined that the second slot transmits the D2D periodic message according to the resource configuration message, the remaining slots in the cycle are all non-periodic message slots.
For example, in a fleet of vehicles, when the fleet is parked at a location for rest, the user 1 driving vehicle a may choose to send a small video to the terminal 2 via the terminal 1 to the terminal 2, at a time slot other than the time slot used by the periodic message D2D, thereby enabling sharing of resources between any two vehicles in the fleet.
In summary, the vehicle networking terminal in this embodiment sends D2D periodicity at the fixed time slot of each period, and in other time slots of each period, the user can send messages such as video and audio that do not need to be sent periodically through the vehicle networking terminal according to the requirement, so as to share the resources between the vehicles.
In an embodiment of the invention, if the receiving party does not receive the D2D periodic information sent by the car networking terminal in the current period, the receiving party acquires the D2D periodic information sent by the car networking terminal in the last period, determines possible position information of the receiving party according to the D2D periodic information in the last period, and sends a message to other car networking terminals around the position information, so that the other car networking terminals contact with the car networking terminal according to the information to determine the running state information of the vehicle where the car networking terminal is located.
In order to implement the above embodiments, the present invention also proposes a device-to-device D2D communication apparatus.
Fig. 3 is a schematic structural diagram of a communication apparatus of device-to-device D2D according to an embodiment of the present invention. The communication means of the device-to-device D2D is located in a car networking terminal, as shown in fig. 3, the communication means of the device-to-device D2D includes a setting module 110 and a first processing module 120, wherein:
the setting module 110 is configured to set a transmission cycle of the D2D resource of the internet of vehicles terminal and a slot position for transmitting the D2D periodic message according to the received resource configuration information.
The D2D periodic message is information that needs to be periodically sent according to the car networking function requirement, the D2D periodic message may include, but is not limited to, position information, operating state information, and the like of the vehicle, and in an actual application process, the information that is periodically sent may also be adjusted according to the car networking function requirement, which is not limited in this embodiment.
It should be understood that, in practical applications, the D2D periodicity information may be fixedly transmitted one or more times in each period, wherein the number of times the D2D periodicity information is transmitted in each period is the same as the number of slot positions.
The operating state information of the vehicle may include, but is not limited to, a vehicle speed, an acceleration, a deceleration, failure information, etc. of the vehicle.
The first processing module 120 is configured to, for each sending cycle, send the current D2D periodic message to the receiving side when the slot position of the D2D periodic message in the current sending cycle is monitored to arrive.
At the slot position in each cycle, the first processing module 120 takes the current D2D periodic messages for the vehicle and sends the current D2D periodic messages to the recipient.
In one embodiment of the present invention, in order to allow the receiving side to identify the sender of the information, in the process of sending the current location information and/or the current operation state information of the vehicle to the receiving side, the first processing module 120 may also send its own identification information while sending the current location information and/or the current operation state information. The receiving party determines the sending party of the D2D periodic message through the identification information.
In summary, the vehicle networking terminal of the embodiment periodically sends the D2D periodic message, so that the receiving party can determine the location information and the operating state information of the vehicle where the vehicle networking terminal is located according to the received D2D periodic message.
It should be noted that the foregoing explanation on the embodiment of the communication method of the device-to-device D2D is also applicable to the communication apparatus of the device-to-device D2D of the embodiment, and the implementation principle thereof is similar, and is not described herein again.
According to the communication device of the device-to-device D2D, the setting module sets the sending period of the D2D resource and the time slot position of the D2D periodic message according to the received resource configuration information, and the first processing module sends the D2D periodic message to the receiving party in the fixed time slot of each period, so that the vehicle networking terminal can send the D2D periodic message periodically, and the receiving party can provide reliable bases for subsequent vehicle networking services (such as vehicle early warning and vehicle fault analysis) according to the received D2D periodic message. Particularly, when the D2D periodically contains the position information and the operation state information of the vehicle, the receiving party monitors the position of the vehicle according to the position information, and timely knows the operation state of the vehicle where the terminal of the internet of vehicles is located through the operation state information.
In an embodiment of the present invention, on the basis of fig. 3, as shown in fig. 4, the apparatus may further include a second processing module 130, where the second processing module 130 is configured to, when sending the aperiodic information, select other time slots than the time slot used by the D2D periodic message to send the aperiodic message.
The aperiodic message refers to a message that does not need to be periodically sent to the receiving party, and may include, but is not limited to, video, audio, pictures and texts, and may also include warning information.
That is, the second processing module 130 may transmit aperiodic messages in the aperiodic message slots in each cycle, i.e., messages that do not need to be transmitted periodically may be transmitted in the internet of vehicles.
The aperiodic message time slot refers to a time slot in which the D2D periodic message does not need to be transmitted.
For example, a cycle is divided into ten slots, and if it is determined that the second slot transmits the D2D periodic message according to the resource configuration message, the remaining slots in the cycle are all non-periodic message slots.
In summary, it can be seen that the second processing module 130 sends D2D periodicity at a fixed time slot of each period, and in other time slots of each period, a user can send messages such as video and audio which do not need to be sent periodically to a receiving party through a vehicle networking terminal according to needs, so as to share resources between vehicles.
The aperiodic message refers to a message that does not need to be periodically sent to the receiving party, and may include, but is not limited to, video, audio, pictures and texts, and may also include warning information.
In an example of the present invention, as shown in fig. 4, the apparatus may further include a receiving module 140, where the receiving module 140 is configured to receive the location information of the other vehicle sent by the sender terminal, to perform collision warning, lane change warning, and the like according to the location information of the other vehicle, or to provide the location information of the other vehicle to the user, so that the user knows the location information of the other vehicle in the fleet.
In order to realize the embodiment, the invention further provides the Internet of vehicles terminal.
A terminal of a vehicle networking comprising communication means of a device to device D2D of an embodiment of the second aspect of the invention.
According to the vehicle networking terminal, the sending period of the D2D resource and the time slot position for sending the D2D periodic message are set according to the received resource configuration information, and the D2D periodic message is sent to the receiving party at the fixed time slot of each period, so that the vehicle networking terminal can send the D2D periodic message periodically, and the receiving party can provide reliable bases for subsequent vehicle networking services (such as vehicle early warning and vehicle fault analysis) according to the received D2D periodic message. Particularly, when the D2D periodically contains the position information and the operation state information of the vehicle, the receiving party monitors the position of the vehicle according to the position information, and timely knows the operation state of the vehicle where the terminal of the internet of vehicles is located through the operation state information.
