Background technique

With the development of communication technology, Vehicle Networking communication has emerged as an application of wireless communication technology. Broadly speaking, car-network communication is the communication in which vehicles participate in wireless communication, that is, the use of advanced wireless cellular communication technology to realize real-time information (vehicle networking information) interaction between vehicles and vehicles, vehicles and roadside infrastructure, such as notification The current state of each other (such as the position, speed, acceleration, and driving route of the vehicle) and the learned road environment information, the cooperative perception of the road dangerous situation, and timely provision of various collision warning information to prevent the occurrence of traffic accidents.

At present, the modes of vehicle networking communication are specifically divided into three types: V2V (Vehicle-to-Vehicle Communications), Vehicle-to-Infrastructure Communications (V2I), and Vehicle Communication (V2P, Vehicle- to-Pedestrian Communications). Wherein, V2I generally refers to communication between a vehicle UE and a Road Side Unit (RSU); the RSU is an entity that supports V2I services, and can be implemented by a base station or a stationary UE or an independent network element. Generally, the above three communication modes are collectively referred to as V2X (Vehicle-to-Everything) communication.

detailed description

The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

The vehicle networking information referred to in this embodiment refers to real-time information of interaction between the vehicle and the vehicle, the vehicle and the roadside infrastructure, for example, informing each other of the current state (such as the position, speed, acceleration, driving path of the vehicle) and the learned Road environment information, collaborative perception of road hazard conditions, timely provision of multiple collision warning information, etc.; vehicle networking information can also be other conceivable information, which is not limited here.

It should be noted that the description of the subsequent scheme shows that the scheme proposes the transmission standard of the vehicle networking information in the V2X mode. The standard is simple and easy to implement, and has strong portability, and can effectively realize the information of the vehicle networking in the transmitting device and receiving. Transfer between devices. When the transmitting device and the receiving device simultaneously transmit the information by using the transmission standard, not only the transmission of the vehicle networking information between the transmitting device and the receiving device but also the low-latency transmission of the vehicle network can be realized, to a certain extent. Meet the low-latency characteristics of the Internet of Vehicles, thereby improving the transmission performance of the Internet of Vehicles.

1 is a schematic flowchart of an implementation process of a vehicle network information transmission method applied to a transmitting device according to an embodiment of the present invention; as shown in FIG. 1, the method includes:

Step 101: Identify the data packet to be sent as the vehicle networking information;

Here, the vehicle networking UE/vehicle UE (sending device) having the Internet of Vehicles function generates the vehicle networking information according to the current actual application situation of the vehicle. For example, the vehicle-mounted UE1 installed on the vehicle A detects that the vehicle A has a safety function abnormality, then the vehicle The UE1 generates a runaway warning message; if the vehicle A in which the UE1 is installed suddenly stops in the middle of the road, the UE1 generates a warning vehicle warning DENM message; if, for example, the vehicle A in which the UE1 is installed wants to be programmed into the driving queue, the UE1 generates the formation driving information. . Among them, the out-of-control warning information, the vehicle warning DENM message, and the formation driving information can be used as one type of vehicle networking information to be transmitted. The information is packaged to form a data packet, and the identification data packet carries the vehicle networking information.

It should be understood by those skilled in the art that the above is only a specific example of the information of the Internet of the Internet to be transmitted. The information about the Internet of the vehicle to be transmitted in the embodiment of the present invention may also be in any other conceivable form. The data packet carries an IP (Internet Protocol) header or does not carry an IP header.

Correspondingly, the data packet to be sent is the information of the vehicle networking, and specifically includes:

When the sending device assembles the data packet into a Packet Data Convergence Protocol (PDCP) Protocol Data Unit (PDU), the PDU type field of the PDCP subheader is set to the information type related to the Internet of Vehicles. Or protocol type; and/or, when the data packet is assembled into a media access control layer (MAC), the target identifier field in the MAC subheader is set as a roadside unit identifier, a roadside unit broadcast identifier. a roadside unit multicast identifier, a car network multicast identifier, or a car network broadcast identifier; and/or, when assembling the data packet into a MAC PDU, setting a target identifier field in the MAC subheader to be carried by the data packet The multicast or broadcast identifier corresponding to the type of the Internet of Vehicles information; the data packet is assembled into a Radio Resource Control (RRC) signaling, and the message type in the RRC signaling is indicated as an Internet of Vehicle type. It can be seen that none of the foregoing data packets carry an IP header. This identification method is implemented by identifying the vehicle network information in corresponding fields on the PDCP and MAC layers. The sending device may indicate by the PDU type field carried by the PDCP subheader Which data packet is a data packet of the car network information type, so that the receiving device can recognize the information of the car network. In addition, the receiving device does not need to perform IP layer processing on the data packet that does not carry the IP header, which saves processing resources.

The logical channel identification field of the MAC subheader may also be set to the logical networking channel identifier of the vehicle network, that is, the transmitting device and the receiving device may transmit the data packet carrying the vehicle networking information through the pre-committed vehicle networking bearer or the vehicle networking logical channel. .

In addition, the sending device sets the destination internet protocol IP address carried by the data packet to an IP address of the roadside unit, a car network multicast IP address, or a car network broadcast IP address; and/or, the purpose of carrying the data packet The IP address is set to the multicast IP address corresponding to the type of the car networking information carried by the data packet. The aforementioned data packet is a data packet carrying an IP header. The receiving device that interacts with the transmitting device to perform car network information may be a base station, a roadside unit, or a UE adjacent to the sending device. The sending device can conveniently identify the receiving device by setting the IP address to a corresponding form. Eligible to receive the packet.

In the foregoing solution, before the assembling the data packet into a MAC PDU, before the target identifier field in the MAC sub-header is set as the roadside unit identifier, the sending device initiates the roadside unit RSU discovery, and obtains the corresponding RSU. The device identifier is used as the roadside unit identifier.

Step 102: Send the identified data packet.

Here, the data packet that has been identified as the Internet of Vehicles information may be mapped to the pre-configured car network bearer or the car network logical channel for transmission; or the data packet that has been typed as the car network information type may be passed through the cellular network or device to Device D2D communication transmission.

Before the sending the identified data packet, the method further includes: the sending device acquiring the vehicle networking configuration information of the sending device; performing the configuration of the vehicle network transmission according to the vehicle networking configuration information; The identified data packet is transmitted. The sending device may receive the base station, the terminal-to-terminal D2D network element ProSe Function, or the vehicle networking configuration information sent by the vehicle networking function entity; or, from the universal integrated circuit card UICC built in itself or The car ID configuration information is read on the SIM card of the household identification card. The vehicle network configuration information at least includes: a vehicle network support indication and a vehicle network information transmission resource pool; the vehicle network support indication is indicated to support transmission of the vehicle networking information, and the vehicle network information transmission resource pool may be the same as the current UE1 and the current UE1 The neighboring UEs of the frequency or inter-frequency serving cell transmit which resource blocks RB on which subframe the car network information uses. In addition, if the scheduling allocation principle is adopted, the vehicle networking configuration information may further include at least one of the following: a temporary identifier of the Internet of the air-conditioning network, a temporary identification of the air-network multicast/broadcast service air interface network, a modulation and coding mode, a vehicle network bearer configuration, and a vehicle. Networked information transmission maximum transmission power, roadside unit identification or roadside unit broadcast/multicast identification or vehicle network multicast/broadcast identification, vehicle networking information type corresponding to the vehicle network multicast/broadcast identification, base station/roadside unit IP address, car network multicast/broadcast IP address, car network port number of base station/roadside unit, car network multicast/broadcast port number, and multicast IP address corresponding to car network information type. For the transmitting device, the car network information transmission resource pool is a sending resource pool; for the receiving device, the car network information transmission resource pool is a receiving resource pool.

In this embodiment, the car network bearer configuration further includes at least one of the following: a bearer identifier; a bearer type, which may include a PC5 bearer or a Uu bearer type; a logical channel identifier; a logical channel group identifier; a priority; a priority bit rate; Size duration; periodic buffer status reporting timer; retransmission buffer status reporting timer; serial number field size; reordering timer; discard timer; maximum connection identifier; compression algorithm; PDCP sequence number size; .

If the car network configuration information is not configured before the transmitting device and the receiving device transmit or receive the car network information, the sending device and the receiving device also need to send the car network configuration request information to the base station to request the transmission of the car network information interaction. The resources, under the conditions that have been configured with the vehicle networking configuration information, can smoothly carry out the interaction of the vehicle networking information. The car networking configuration request information includes at least one of the following: car network information transmission and/or receiving interest indication; interested car network service/application/information type; car networking service/vehicle networking application/car networking information Priority; car network bearer/logical channel establishment request; car network information transmission range; transmitting device The expected vehicle network information transmission range; the vehicle network information transmission period; the amount of resources required for the vehicle network information transmission; the transmission equipment movement level; the IP address of the transmitting device; and the vehicle networking application port number of the transmitting device.

In addition, before the sending device, such as the UE, sends the car network configuration request information to the base station, if the UE is in an idle state and receives the car network information transmission resource pool broadcast by the base station, the UE can send the neighboring UE and the PC through the PC5 interface. Or the roadside unit sends the vehicle networking information;

If the UE is in an idle state and only receives the car network support indication broadcasted by the base station indicating that the car network information transmission resource pool is not received, the UE enters a connected state and sends the car network configuration request information to the base station to request the base station to Allocate a transport resource block.

In the foregoing solution, the information required to be carried in the data packet of the transmitting device and the configuration information that needs to be preset are specified, that is, a new transmission standard of the vehicle networking information is proposed, and the transmission standard can not only realize the vehicle. The effective transmission of the networked information in the transmitting device and the receiving device can also realize the low-latency transmission of the car network to achieve the low delay characteristic of the car network transmission.

The embodiment of the invention further provides a computer storage medium, wherein the computer storage medium stores computer executable instructions, and the computer executable instructions are used to execute the foregoing vehicle networking information transmission method in the application connection sending device.

Here, the receiving device receives the car network information sent by the transmitting device by using the configured car network configuration information, such as the receiving resource pool.

Step 202: Parse the data packet.

Here, the receiving device is at least one of a terminal UE, a roadside unit, and a base station; because the data packet carrying the car network information has been identified as described above in the transmitting device, in this step, the receiving device The packet needs to be parsed.

Step 203: Deliver the vehicle networking information according to the parsing result of the data packet.

Specifically, when the UE or the roadside unit detects that the PDU type field of the PDCP subheader of the received data packet is an information type or a protocol type related to the Internet of Vehicles, the UE or the roadside unit delivers the data packet to Car networking protocol layer; and/or,

The embodiment of the invention further provides a computer storage medium, wherein the computer storage medium stores computer executable instructions, and the computer executable instructions are used to execute the foregoing vehicle network information transmission method applied in the receiving device.

The technical solution will be further described below with reference to FIG. 4 to FIG. 10 and application scenarios 1 to 6.

In the following application scenarios, the carrying information and the configuration information that needs to be preset are described in the sending device, that is, the solution proposes a new transmission standard of the vehicle networking information in the V2X mode, and the receiving device is based on The information sent by the sending device parses the data packet and performs corresponding delivery, so that the effective transmission of the car network information in the transmitting device and the receiving device can be realized. Based on the transmission standard, not only can the effective transmission of the car network information in the transmitting device and the receiving device be realized, but also the low-latency transmission of the car network can be realized, so as to meet the low delay characteristic of the car network transmission.

Application scenario 1:

Vehicles A and B are respectively installed with UE1 and UE2 having the Internet of Vehicles function. UE1 and UE2 may be in the UMTS terrestrial radio access network E-UTRAN network coverage state, and the E-UTRAN network supports the car networking function. When there is network coverage, UE1 and UE2 may obtain the car network configuration information from the base station in advance to obtain transmission resources of the respective transmission car network information. UE1 and UE2 may also be in a state of no network coverage. In this case, UE1, UE2 may use the car network configuration information that has been pre-stored on the respective UICC or SIM, or obtain the configured configuration from the ProSe Function or the vehicle networking function entity in advance. Car networking configuration information.

In this application scenario, the UE1 detects that the vehicle A has a safety function abnormality, and hopes to send a runaway warning message to the vehicles around it. The application layer of the Internet of Vehicles UE1 generates a car network message with a runaway warning message. After receiving the message from the application layer, the access layer of the UE1 packs the message into a data packet, and the UE1 identifies the data packet of the vehicle network. Specifically, at the PDCP layer of the UE1, the UE1 assembles the data packet into a PDCP PDU format, and sets the PDU type field of the PDCP subheader to an information type or protocol type related to the Internet of Vehicles, to identify the data packet as a bearer network. Packet of information. At the MAC layer of UE1, UE1 assembles the data packet into a MAC PDU, and sets the target identification field in the MAC subheader to a broadcast identifier or a car network broadcast identifier; of course, the target identifier field in the MAC subheader may also be set to The broadcast identifier corresponding to the runaway warning message. Then, the UE1 transmits the resource pool using the previously known vehicle networking configuration information, such as the car network information, and transmits the data packet carrying the runaway warning information through the PC5 interface.

The vehicle network UE2 adjacent to the UE1 monitors the pre-known vehicle network information receiving resource pool. When it listens to the data packet sent by the UE1 through the PC5 interface, it first detects the target identifier field in the MAC subheader, and if the field is detected as broadcast The identifier, the car network broadcast identifier or the broadcast identifier corresponding to the runaway warning message of interest to the UE2, the UE2 delivers the data packet to the RLC layer and the PDCP layer of the UE2 for further analysis. At the PDCP layer, if UE2 detects that the PDU type field of the PDCP subheader of the data packet is an information type or protocol type related to the Internet of Vehicles, UE2 delivers the data packet to the car network application layer/high layer without going through the IP layer. deal with. After receiving the runaway warning message, the application layer of UE2 further determines whether the event is related to the vehicle in which UE2 is installed, if a warning is issued to the driver of UE2. The protocol layer includes a PDCP, a Radio Link Control (RLC), and a MAC layer in the Long Term Evolution (LTE) system. The application scenario 1 can be seen in FIG. 3(d) and FIG.

Application scenario 2:

Vehicles A and B are respectively installed with UE1 and UE2 having the Internet of Vehicles function. UE1 and UE2 are in the E-UTRAN network coverage state, and the E-UTRAN network supports the car networking function. When the vehicle A in which the UE 1 is installed suddenly stops in the middle of the road, the application layer of the UE 1 generates a warning vehicle warning DEMN message, which is desired to be transmitted to the vehicles around it.

When the UE1 is in an idle state and receives only the car network support indication information and/or the car network information receiving resource pool broadcast by the base station, but does not receive the car network information transmission resource pool, the UE1 enters the connected state from the idle state, The base station sends the vehicle networking configuration request information, where the request information may include a car network information transmission and/or reception interest indication, a car network service/application/information type that the UE1 is interested in, and the like. After receiving the configuration request information, the base station sends the vehicle networking configuration information, such as the car network information transmission resource pool, to the UE1.

After receiving the car network configuration information sent by the base station, the UE1 performs configuration according to the car network configuration information, and marks the warning vehicle alarm DEMN message into a data packet. When UE1 assembles the data packet into a PDCP PDU, the PDU type field of the PDCP subheader is set to the information type or protocol type related to the Internet of Vehicles; when the data packet is assembled into a MAC PDU, the target identification field in the MAC subheader is used. Set to broadcast identification or car network broadcast identification to identify the data packet as a data packet carrying the Internet of Vehicles information. The UE1 uses the base station to transmit the resource pool for the assigned vehicle network information and transmits the warning vehicle warning DENM message through the PC5 interface.

The vehicle network UE2 adjacent to the UE1 monitors the allocated network of the vehicle network information received by the base station. When it listens to the data packet sent by the UE1 through the PC5 interface, it first detects the target identification field in the MAC subheader, if the field is detected. For broadcast identification or car network broadcast identification, UE2 delivers the data packet to the RLC layer and PDCP layer of UE2 for further resolution. When the PDCP layer detects that the PDU type field of the PDCP subheader of the data packet is the information type or protocol type related to the Internet of Vehicles, the UE2 delivers the data packet to the car network application layer/upper layer. UE2's car networking application layer received After alerting the vehicle to alert the DENM message, it is further determined whether the event is related to the vehicle in which the UE 2 is installed, if a warning is issued to the driver of the UE 2. The foregoing description will be understood in conjunction with FIG. 3(d) and FIG.

In this embodiment, for the car network configuration request of the UE1, the base station may further configure different car network information transmission and/or reception resource pools for different supported car network information/service/application types; and may also only configure the UE1 for the UE1. Corresponding to the car network information transmission and/or receiving resource pool corresponding to the car network service/application/information type of interest of the UE1; the UE1 may also be configured to send and/or receive resource pool information of the neighboring cell, and the neighboring cell It may be a cell of the same frequency and/or different frequency as the serving cell to which the UE1 belongs. If the base station wants the UE1 to adopt the scheduling resource allocation, the base station may configure the UE1 with the air interface network temporary identifier, the modulation and coding mode, the vehicle network multicast/broadcast identifier, and the like for scheduling the vehicle network transmission resource. The specific configuration of the UE to the UE is flexibly set according to the actual situation, and is not described here.

Application scenario 3:

The vehicle A is equipped with a UE1 having a car networking function. The vehicle in which UE1 is installed wishes to use the automatic parking system for automatic parking. A small cell deployed at the entrance of the parking lot acts as an RSU. When the vehicle A needs to enter the parking lot, the UE1 initiates an RSU discovery. When the UE1 detects that the serving cell (base station) where the RSU is located broadcasts the RSU support indication and indicates that the RSU supports the automatic parking service, the UE1 may send the car network configuration to the RSU. Request information, the vehicle networking configuration request information may include a car network service/application/information type of interest to the UE1, a priority of the UE/vehicle networking service/vehicle networking application/vehicle networking information, and a car network information transmission period.

After receiving the configuration request information, the RSU, which is served by the base station, sends the vehicle networking configuration information to the UE1, where the configuration information includes the Temporary Identification of the Internet of the Internet of the Internet of the Internet, the temporary identification of the Internet of the multicast/broadcast service, the modulation and coding mode, and the vehicle network. The vehicle-mounted multicast/broadcast identification corresponding to the bearer configuration and various types of vehicle networking information types; See the previous description. Preferably, the base station may configure multiple car network bearers for the UE1 according to the type and priority of the car network information that the UE is interested in, and send the car network configuration information to the UE1.

After receiving the vehicle network configuration information sent by the base station, the UE1 performs the vehicle network bearer configuration according to the vehicle network configuration information, and then packs the automatic parking request information generated by the UE1's vehicle network upper layer into a data packet, and then identifies the logical channel identifier of the MAC subheader. The field is set to the car network logical channel identifier, and the data packet carrying the automatic parking request information is mapped to the vehicle network bearer or the vehicle networking logical channel; finally, the UE1 uses the uplink cellular network resource to send the data packet carrying the automatic parking request information to the service. Community.

The serving cell receives the data packet, and according to the logical channel identifier field of the MAC layer, detects that the data packet is transmitted through the car network bearer, and the serving cell delivers the data packet to the RSU. After receiving the automatic parking request information, the RSU authenticates the information and decides whether the UE1 can be allowed to enter the parking. If the release is allowed, the vehicle A is notified that the parking can be entered into the parking lot. This application scenario can be understood in conjunction with FIG. 3(a) and FIG. In this application scenario, the RSU can be acted upon by the base station, and can also be acted upon by the UE as shown in FIG. 3(b) and 3(c).

In the foregoing application scenarios 1 to 3, the data packet carrying the car network information does not carry the IP header, and does not need to be processed by the IP layer of the UE2/RSU, thereby saving processing resources. At the same time, the data packet is identified as a data packet carrying the vehicle networking information through a corresponding field or a dedicated vehicle network bearer, and the method is simple and portable, and has strong portability. In addition, by analyzing the target identification field in the MAC sub-header in the data packet, the PDU type field of the PDCP sub-header, and the logical channel identification field of the MAC layer, the protocol for delivering the data packet carrying the vehicle networking information to the vehicle network is determined. Layers or high-levels avoid the spread of car networking information to the core network.

Application scenario 4:

Vehicles A and B are respectively installed with UE1 and UE2 having the Internet of Vehicles function. UE1 and UE2 are at The E-UTRAN network covers the state, and the E-UTRAN network supports the car networking function. When the vehicle A in which the UE 1 is installed suddenly stops in the middle of the road, the vehicle networking application layer of the UE 1 generates a warning vehicle warning DEMN message, which is desired to be transmitted to the vehicles around it.

Assuming that the UE1 is in an idle state, only receiving the car network support indication information and/or the car network information receiving resource pool broadcast by the base station, but not receiving the car network information transmission resource pool, the UE1 enters the connected state and sends the car network configuration to the base station. Request information, which may include a car network information transmission and/or reception interest indication, a car network service/application/information type of interest to the UE1, and a priority of the car networking information. In addition, the UE1 may send the car network buffer state report information to the base station, where the information carries the logical channel group identifier corresponding to the car network bearer. After receiving the report, the base station dispatches the car network information transmission resource pool for the UE1, and uses the car network air interface network. The temporary ID is used to deliver the allocated resources.

After receiving the car network configuration information sent by the base station, the UE1 configures according to the car network configuration information, and packages the warning vehicle alarm DEMN message into a data packet, and when the data packet is assembled into a MAC PDU, the target identifier in the MAC sub-header is used. The field is set to the car network multicast/broadcast identity, and the data packet carries the IP header and configures its destination IP address as the broadcast address. The UE1 then transmits the resource pool using the car network information acquired from the base station and transmits the alert vehicle warning DENM message through the PC5 interface.

When the neighboring vehicle UE2 monitors the data packet sent by the UE1 through the PC5 interface by the base station information receiving resource pool allocated by the base station, it determines the target identifier field in the MAC subheader, if the identifier field is the vehicle network multicast/broadcast For identification, UE2 delivers the data packet to the upper layer/application layer of UE2 for subsequent processing. After receiving the warning vehicle warning DENM message, the UE2's car network high-level/application layer further determines whether the event is related to the vehicle in which the UE2 is installed, if a warning is issued to the driver. For an understanding of the application scenario, please refer to Figure 3(d) and Figure 7 of the aforementioned car networking architecture.

In this embodiment, the base station can also match different supported vehicle networking information/service/application types. Depending on the vehicle network information transmission and/or reception resource pool, the UE1 may only configure the vehicle network information transmission and/or reception resource pool corresponding to the vehicle network service/application/information type of interest of the UE1; The UE1 configures the car network of the neighboring cell to transmit and/or receive resource pool information, and the neighboring cell may be a cell with the same frequency and/or different frequency as the serving cell where the UE1 is located. If the base station wants the UE1 to adopt the scheduling resource allocation, the base station may configure the UE1 with the air interface network temporary identifier, the modulation and coding mode, the vehicle network multicast/broadcast identifier, and the like for scheduling the vehicle network transmission resource. The specific configuration is flexibly set according to the actual application.

Application scenario 5:

The vehicle A is equipped with the UE1 having the Internet of Vehicles function. The vehicle in which UE1 is installed wishes to transmit the detected road safety information to the RSU. The RSU acts as a UE or small cell deployed alongside the road. When the vehicle A wants to report the road safety information, the UE1 initiates the RSU discovery. If the UE1 detects that the nearby UE or the RSU broadcast by the base station has an RSU support indication, the UE1 may send a car network configuration request to the RSU, and the request may include the vehicle network. The information transmission interest indicates the car network service/application/information type of interest, the IP address of UE1, and the like.

After receiving the configuration request, the RSU served by the UE or the base station sends the vehicle networking configuration information to the UE1, where the configuration information includes the vehicle network bearer, the IP address of the RSU, and the port number. Please refer to the above description for the contents of the car network. When the in-vehicle UE and the RSU implement unicast communication, they can find each other through the IP addresses of the other party (the IP address of UE1 and the IP address and port number of the RSU). In addition, the RSU served by the UE or the base station may also configure multiple car network bearers for the UE1 according to the type and priority of the car network information that the UE is interested in, and send the car network configuration information to the UE1.

After receiving the vehicle network configuration information sent by the RSU served by the UE or the base station, the UE1 performs the vehicle network bearer configuration according to the vehicle network configuration information, and then packs the road safety information generated by the UE1 vehicle network upper layer into a data packet, and the MAC subheader logic. The channel identification field is set to the vehicle network bearer identifier or the vehicle network logical channel identifier, and the data packet is mapped to the vehicle network bearer or the vehicle networking logic. On the channel. Finally, UE1 transmits a data packet carrying road safety information to the RSU served by the UE or the base station using a PC5 interface (the UE acts as an RSU) or a Uu interface (the base station acts as an RSU).

After receiving the message, the RSU served by the UE or the base station detects that the data packet is transmitted through the car network bearer or logical channel according to the logical channel identification field of the MAC layer, and the RSU delivers it to the upper layer/application layer. For an understanding of the application scenario, please refer to Figure 3(a), (b), (c) and Figure 8 of the aforementioned car network architecture.

Application scenario 6:

The vehicle A is equipped with the UE1 having the Internet of Vehicles function. The vehicle in which UE1 is installed joins the formation fleet and wishes to report this information to the nearby RSU. The RSU acts as a base station deployed alongside the road.

Send the indication of interest, the IP address and port number of UE1, and so on. Here, the IP address and port number of the UE1 are transmitted in order to enable the two parties of the car network to find each other according to the address and port number provided by the other party when the unicast is implemented.

After receiving the configuration request information, the RSU served by the base station sends the vehicle networking configuration information to the UE1, where the information includes at least the IP address and the port number of the RSU. After receiving the car network configuration information sent by the RSU served by the UE or the base station, the UE1 reports the IP address and port number information of the RSU to the upper layer of the car network. UE1's car network high-level generates the formation driving report information, and packs the information into data packets, and configures the target address and port number of the IP header to be the destination address and port number of the RSU, respectively, and maps the data packet to the cellular bearer. Finally, UE1 uses the uplink cellular resources of the Uu interface to transmit a data packet carrying the formation driving report information to the RSU served by the base station.

After receiving the data packet, the RSU acting as the base station detects the IP header of the data packet. If the target address in the IP header is detected as the address of the RSU, the base station delivers the data packet to the application layer of the RSU having the address. For an understanding of the application scenario, please refer to the aforementioned car network architecture. Figure 3 (a) And Figure 9.

In the foregoing application scenarios 4-6, the data packet carrying the car network information carries the IP header, and the data packet is carried by the mapping to the dedicated bearer channel or the cellular bearer negotiated by the communication parties. A data packet having the car network information, and the receiving device capable of receiving the car network information is known through the target address in the IP packet header. This method is simple and easy to implement and has a strong portability. In addition, it is determined that the data packet carrying the Internet of Vehicles information is delivered to the protocol layer or the upper layer, thereby avoiding the spread of the vehicle networking information to the core network.
