Detailed Description
The technical solution of the present invention is further described in detail with reference to the drawings and the specific embodiments of the specification.
As shown in fig. 1, the present embodiment provides a vehicle-to-arbitrary device V2X data transmission method, including:
step S110: acquiring communication state information of a communication link of V2X;
step S120: when the communication state information does not meet the preset communication condition, encapsulating the V2X data packet to be transmitted into a first data packet suitable for the transmission of the cellular network;
step S130: transmitting the first data packet to a predetermined server through the cellular network; wherein the first data packet is for forwarding by the predetermined server to a V2X recipient via the cellular network.
In this embodiment, the step S110 of acquiring the communication status information of the communication link of V2X may include sending an information acquisition request to the device storing the communication status information, and receiving the communication status information returned based on the acquisition request. The step S110 may further include: and intercepting the communication link, and determining whether the frequency spectrum resources corresponding to the communication link of the V2X are occupied or not and whether the frequency spectrum resources are interfered or not, so as to obtain the communication state information. The step S110 may further include: and sending the detection data packet to the receiving end of the V2X, and receiving information returned by the opposite party based on the detection data packet. If the returned information is not received, or the received returned information is overtime or the received returned information is incorrect, the communication state information of the communication link of the current V2X is considered to be poor, and the data transmission quality of the V2X data packet cannot be ensured.
In summary, in this embodiment, the communication status information of the communication link of the current V2X is obtained, and the communication status information can be used to determine whether the communication link of the current V2X has congestion, interference or interruption, so as to determine the reliability of the communication link of the current V2X.
In step S120, if it is determined that the current communication link of V2X is unreliable, the communication status information is considered to not satisfy the preset communication condition, for example, if it is determined that the available bandwidth of the communication link of V2X is lower than a first threshold, the interference is higher than a second threshold, or the information returned by the V2X receiving end is not received, and the information is overtime, the communication status information is considered to not satisfy the preset communication condition. At this time, in order to ensure the normal communication of the V2X data packets, in this embodiment, the V2X data packets to be transmitted are protocol-converted, i.e., re-encapsulated, into the first data packets suitable for cell transmission. The contents in the V2X data packet or the V2X data packet are transferred in the cellular network, so that the problem that the current urgent V2X data cannot be transmitted due to poor communication state of a communication link is avoided, and timely transmission and high-quality transmission of the V2X data are ensured.
For example, in order to avoid causing serious vehicle congestion, when a traffic accident occurs at a certain place, the vehicle a uses the vehicle-mounted device to send the warning information, prepares to perform data transmission by using the V2X technology, and may find that the current fog is large and the geographic location causes the communication state of the communication link to be very poor during transmission, and in order to forward the warning information as soon as possible, in this embodiment, the V2X data packet is re-encapsulated into the first data packet suitable for the cellular network transmission; the first data packet is sent to a base station of the cellular network, which forwards it to the predetermined server. The predetermined server may be a V2X application server in this embodiment, dedicated to handling V2X data forwarded by such a cellular network. The predetermined server may also be various servers with integrated functions, such as a Mobile Edge Computing (MEC) server, and the MEC server may forward the first data packet to the corresponding target receiving end by identification, so as to ensure smooth and high-quality transmission of the V2X data.
In this embodiment, the cellular network may be a Long Term Evolution (LTE) network, and specifically may be a 3G, 4G, or 5G network. Further, in the present embodiment, the V2X data may include data transmitted using LTE V2X Communication indication and/or data transmitted using Dedicated Short Range Communication (DSRC).
In some embodiments, the step S120 may include:
disassembling the V2X data packet and extracting predetermined information in the V2X data packet;
and encapsulating the predetermined information into the first data packet according to a communication protocol corresponding to the cellular network.
In this embodiment, the V2X packet that has been encapsulated according to the V2X protocol needs to be unpacked first, and useful data, such as a payload, in the V2X packet is extracted. The useful data or payload is the data that the device needs to send to the V2X receiver. Both the useful data and the payload belong to one of the predetermined information. The first data packet thus formed is encapsulated based on the communication protocol of the cellular network and is of course suitable for transmission in the cellular network. The predetermined server is a server connected to a cellular network.
In some embodiments, the step S120 includes:
and encapsulating the V2X data packet and the V2X application indication according to a communication protocol corresponding to the cellular network to form the first data packet.
In this embodiment, when the first data packet is formed by encapsulation, the V2X data packet with the encapsulation number is not disassembled, but the entire V2X data packet and the V2X application instruction are directly encapsulated to form the first data packet. The V2X application here indicates V2X service data for indicating that data encapsulated in the first packet is applied for V2X. Obviously, the V2X can be directly packaged without disassembling in the method, and the method has the characteristic of simple operation.
The step S120 may further include:
encapsulating the V2X data packet and the forwarding priority information into a first data packet suitable for cellular network transmission; wherein the forwarding priority information is used for the predetermined server to determine a forwarding timing for forwarding the first packet.
In this embodiment, forwarding priority information of the V2X packet is obtained, and the forwarding priority information can be determined according to data such as the urgency and data type of the V2X data in the V2X packet. The higher the forwarding priority indicated by the forwarding priority information is, the higher the forwarding priority information is, the predetermined server will forward preferentially. For example, in the driving process, V2X data for warning that the road surface is slippery and V2X data for urgent rescue of a traffic accident occurring in front of the warning are formed, and obviously, the priority of the V2X data for warning that the road surface is slippery is lower than that of the V2X data for urgent rescue of a traffic accident occurring in front of the warning, so as to ensure that V2X data with higher emergency degree is forwarded preferentially, and delay of rescue is avoided.
In some embodiments, when the communication status information satisfies the preset communication condition, the V2X data packet is transmitted to the V2X receiving end through the communication link of V2X. In this embodiment, of course, if the communication status of the communication link of V2X is good, in order to reduce the occupation of communication resources of the cellular network and to reduce the delay of data transmission, the data packet is transmitted directly by using the communication link of V2X, so that the V2X receiving end can receive the V2X data packet and perform subsequent operations.
In summary, in the present embodiment, according to the communication state of the communication link of V2X, the relay is performed through the cell network which is currently laid, so as to ensure the smoothness and transmission quality of V2X data transmission.
As shown in fig. 2, the present embodiment provides a vehicle-to-arbitrary device V2X data transmission method, including:
step S210: receiving a first data packet forwarded by a cellular network; the first data packet is formed by a V2X sending end and sent to a V2X receiving end;
step S220: the first data packet is transmitted using a cellular network.
In the present embodiment, the method may be a V2X data transmission method applied to the predetermined server. In this embodiment the intended server will be subject to the first data packet; the first data packet will continue to be transmitted using the cellular network in step S220. In this embodiment, the step S220 may include broadcasting the first data packet or multicasting the first data packet. If the first data packet is broadcast through the cell network, all terminals residing in the cell can receive the first data packet, and if multicast is performed, only a part of the terminals can receive the first data packet.
In summary, the predetermined server in this embodiment uses the cellular network to forward the first packet including V2X data that should be sent by the communication link of V2X, so as to ensure smooth and high-quality transmission of the V2X packet.
In some embodiments, the step S220 may include:
determining a cell to forward the first data packet;
broadcasting the first data packet through the determined cell.
In this embodiment, the cell to forward the first packet is determined. For example, the predetermined server receives the first data from the cell a, and the first data includes the first data packet as warning information for warning that the section a has bad weather or the like, which causes difficulty in driving. Assuming that one section of the road section A is connected with the road section B, and the other end of the road section A is connected with the road section C; at this time, in order to achieve a better warning effect, it may be necessary to forward the warning information to the cells where the section B and the section C are located to inform that the vehicle entering the section a is going to pay attention to driving safety.
After the cells for forwarding the first data packet are determined, the cells broadcast the first data in respective coverage areas, so that vehicles passing by can receive the alarm information, and driving safety is improved.
Of course, in a specific implementation process, it may be determined that all cells within a predetermined distance from the cell a send the first data packet, for example, the neighboring cells B of the cell a and C of the neighboring cell B may be selected to forward the first data packet, so as to ensure that more V2X receiving ends can correctly receive the V2X data in the first data packet.
Of course, the above is merely an example, and the specific determination of the cell to forward the first packet is not limited to any one of the above methods.
In other embodiments, the step S210 may include: the mobile edge computing MEC server receives a second data packet forwarded by the cell; determining whether the second data packet includes a V2X application indication; determining the data packet comprising the V2X application indication as the first data packet.
The MEC server may receive many packets from the cellular network, but not every packet is the first packet, and in this embodiment, the MEC server parses the second packet, determines whether the second packet includes the V2X application indication, and if the V2X application indication is included, may consider the second packet as the first packet. For example, the MEC server parses the header of the second packet, determines whether the header is the V2X application indication, and forwards the packet to the V2X receiving end through the cell if the header includes the V2X application indication. The forwarding here can be broadcast or multicast.
In some embodiments, the method further comprises: extracting forwarding priority information in the first data packet; determining a forwarding timing sequence for transmitting the first data packet by using a cellular network according to the forwarding priority information; the step S220 may include: transmitting the first data packet with a cellular network based on the forwarding timing.
The predetermined server may receive many first packets to be forwarded, and a phenomenon of shortage of communication resources for forwarding the packets may occur, and at this time, in order to ensure that the transmission delay of the urgent V2X data is further reduced, in this embodiment, the forwarding timing is determined according to the priority information, on one hand, smooth transmission of the V2X data is ensured, and on the other hand, V2X data with high priority or high urgency is ensured to be transmitted preferentially.
As shown in fig. 3, the present embodiment provides a vehicle-to-arbitrary device V2X data transmission method, including:
step S310: receiving a third data packet sent by the cellular network;
step S320: identifying the third data packet and determining whether the third data packet is V2X data forwarded using the cellular network.
The method provided in this embodiment may be applied to a receiving end, and first receives a third data packet sent by the cellular network, and determines whether the third data packet is V2X data forwarded by the cellular network. Certainly, in this embodiment, the V2X receiving end may receive the V2X data from the communication link of V2X, and may also receive the V2X data from the cellular network, so that even if the communication state of the communication link of V2X is not good in the current state, the V2X data may be received, and smooth transmission and high-quality transmission of the V2X data are ensured.
In some embodiments, the step S310 may include: receiving the third data packet broadcast by the cellular network. In this embodiment, the first packets including the V2X data may be broadcast at most, and may of course be multicast, so in this embodiment, in order to receive the V2X data, the third packets of the broadcast are received in step S310, so in step S320, the first packets including the V2X data are identified from the third packets received by broadcast.
In some embodiments, the step S320 may include: when the third data packet is a data packet forwarded by a V2X application server, determining that the third data packet is a first data packet comprising the V2X data; the method further comprises the following steps: and transmitting the first data packet to a cellular communication module for data analysis processing. For example, if the third packet is a packet sent by the V2X application server through a cellular network, the third packet may be confirmed to be the first packet. Therefore, in this embodiment, it can be determined whether the third packet is the first packet according to the source of the third packet. In this embodiment, if the first packet is forwarded by the V2X application server, the packet is directly encapsulated by a communication protocol applicable to the cellular network, so that in this embodiment, the cellular communication module in the receiving terminal can be directly used to perform data analysis processing to obtain V2X data.
In some embodiments, the step S320 may include:
identifying the third data packet;
when the third data packet comprises a V2X application indication, determining that the third data packet is a first data packet comprising the V2X data;
the method further comprises the following steps:
and transmitting the first data packet to a V2X communication module for data analysis processing.
In this embodiment, the first packet may be a packet formed by directly encapsulating a V2X packet, so in this implementation, a cellular communication module first parses the first packet to obtain the V2X application indication, and when it is determined that the V2X data is included, the first packet is further sent to a V2X communication module, and the V2X communication module parses a V2X packet in the first packet by using a communication protocol corresponding to a V2X service, so as to obtain the V2X data.

One specific example is provided below in connection with any of the embodiments described above:
the present example provides a method for V2X data connection based on LTE-assisted handover, including:
the transmitting end of the vehicle-mounted communication terminal performs the following operations:
the first step is as follows: when an on-board sensor or other human triggers the V2X service, V2X data will be sent to the V2X communication module;
the second step is that: when the V2X module receives data, it will trigger an air interface monitoring process to perform reliability detection on the current communication link, where the detection may include congestion detection, interference detection, or other detection methods. The air interface detection result is compared with the corresponding detection level reference:
when the detection result does not exceed the reference threshold, the V2X data is forwarded along the original data link;
when the detection result exceeds the reference threshold, which indicates that the original V2X link is unreliable or interrupted due to congestion, interference or other factors, the V2X data forwarding will start a handover process, and the handover target is the macro network LTE link. The macro network is one of the aforementioned cellular networks.
The third step: switching the transmitted V2X data, first, protocol conversion is performed, and there are two conversion methods for protocol conversion:
the first method is as follows: and (3) disassembling the V2X data packet, extracting information such as V2X service effective load and related service priority, and the like, then packaging the LTE data packet by taking the information as the data effective load of the LTE, and triggering a broadcast application process.
The second method comprises the following steps: the encapsulation of the LTE packet is performed with the V2X packet (including the header portion and the payload portion of the V2X packet) as the payload of the LTE data, and an indication that the packet is for the V2X application is added to the header of the LTE packet.
The fourth step: and then transmitting the LTE data packet with the V2X service after the protocol conversion through an LTE transmitting terminal.
The transmission destination of the LTE packet formed by the first method is an application server for V2X deployed on the network side.
The transmission destination of the LTE packet formed by the second method is an MEC server deployed on the network side.
As shown in fig. 7, a V2X sending terminal obtains V2X data, listens to an air interface, determines whether congestion or interference reaches a threshold, performs protocol conversion and encapsulates the congestion or interference into LTE data if the congestion or interference reaches the threshold, and sends the LTE data to User Equipment (UE) residing in a cell by using a cell network; otherwise, the transmission is carried out by using the V2X link. The V2X link is the communication link of V2X.
When receiving the LTE data packet, the network side completes the following actions:
for an LTE packet formed using the first method:
when the V2X application server receives LTE data sent by the terminal side, the V2X application server determines to perform V2X service broadcast in a specific cell according to the type and priority of the received V2X data, and completes the conversion of broadcast subframes.
For LTE packets formed using mode two:
the MEC server receives LTE data sent by the terminal side, identifies an Internet of vehicles application instruction (namely the V2X application instruction), performs Deep Packet Inspection (DPI) analysis on an LTE data part (namely V2X data), and then determines to perform V2X data broadcasting in a specific cell.
The receiving end of the vehicle-mounted communication terminal needs to complete the following work:
when the receiving end of the vehicle-mounted LTE communication terminal receives the LTE data packet, the LTE data packet is unpacked and analyzed according to the flow, and the LTE communication module identifies the packet head of the LTE data packet:
if the packet header does not contain the vehicle networking application indication identifier, the effective load part of the LTE data packet acts according to the subsequent flow of the LTE module, and the broadcast subframe facing the vehicle networking application carries out subsequent process according to the broadcast service;
if the packet header identifies that the data is oriented to the car networking application, the payload of the LTE packet is extracted and forwarded to the V2X module for subsequent actions (the payload is a complete V2X packet), and after receiving the data, the V2X module performs subsequent actions according to the V2X application process.
As shown in fig. 8, the V2X receiving terminal receives LTE data, unpacks and identifies the packet header, detects whether the LTE data includes a V2X application instruction, and if so, parses the LTE data packet and obtains LTE data; if not, analyzing the V2X data packet in the LTE data packet, extracting the effective load in the V2X data, and acquiring the V2X data.
