Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described below are only for the purpose of illustrating and explaining the present invention, and are not to be construed as limiting the present invention.

The car networking information mentioned in this embodiment refers to real-time information interacted between cars and between cars, and between cars and road side infrastructure, for example, informing each other of the current state (such as the position, speed, acceleration, and traveling path of the car) and the known road environment information, cooperatively sensing a road danger condition, providing various collision warning information in time, and the like; the car networking information may also be other conceivable information, and is not limited herein.

Fig. 1 is a schematic flow chart of an implementation of a vehicle networking information transmission method applied to a sending device according to an embodiment of the present invention; as shown in fig. 1, the method includes:

step 101: identifying a data packet to be sent as Internet of vehicles information;

here, the car networking UE/in-vehicle UE (transmitting device) having car networking function generates car networking information according to the current actual application situation of the vehicle, if the in-vehicle UE1 installed on the vehicle a detects that there is a safety function abnormality of the vehicle a, the in-vehicle UE1 generates out-of-control warning information; if the vehicle A provided with the UE1 suddenly brakes and stops in the middle of the road, the UE1 generates a warning vehicle alarm DENM message; also for example, if the vehicle a in which the UE1 is installed wants to be queued for travel, the UE1 generates queued travel information. The out-of-control warning information, the vehicle warning DENM message and the formation driving information can be used as one of the to-be-sent vehicle networking information. And packaging the information to form a data packet, and identifying that the data packet carries the Internet of vehicles information.

It should be understood by those skilled in the art that the above is only one specific example of the to-be-sent internet of vehicles information, and the to-be-sent internet of vehicles information according to the embodiment of the present invention may be in any other conceivable form. The data packet carries an Internet Protocol (IP) header or does not carry an IP header.

Correspondingly, the identifying the data packet to be sent is the internet of vehicles information, and specifically includes:

when the sending equipment assembles the Data Packet into a Packet Data Convergence Protocol (PDCP) Protocol Data Unit (PDU), setting a PDU type field of a PDCP subheader as an information type or a Protocol type related to the Internet of vehicles; and/or when the data packets are assembled into a Media Access Control (MAC) PDU, setting a target identification field in an MAC subheader as a roadside unit identification, a roadside unit broadcast identification, a roadside unit multicast identification, an Internet of vehicles multicast identification or an Internet of vehicles broadcast identification; and/or when the data packet is assembled into the MAC PDU, setting a target identification field in the MAC subheader as a multicast or broadcast identification corresponding to the type of the vehicle networking information carried by the data packet; and assembling the data packets into a Radio Resource Control (RRC) signaling, wherein the message type in the RRC signaling is indicated as the type of the Internet of vehicles. Therefore, the data packets do not carry IP headers, and the identification method is implemented by identifying the networking information in corresponding fields on PDCP layers and MAC layers. The sending device can indicate which data packet is the data packet of the type of the car networking information through a PDU type field carried by the PDCP subheader, so that the receiving device can conveniently identify the car networking information. In addition, the receiving device does not need to process the data packet without carrying the IP packet header, thereby saving the processing resource.

The logical channel identification field of the MAC subheader may also be set as a car networking logical channel identification, that is, the sending device and the receiving device may transmit a data packet carrying car networking information through a pre-commercialized car networking bearer or a car networking logical channel.

In addition, the sending equipment sets the destination internet protocol IP address carried by the data packet as the IP address of a roadside unit, a multicast IP address of the Internet of vehicles or a broadcast IP address of the Internet of vehicles; and/or setting the destination IP address carried by the data packet as a multicast IP address corresponding to the type of the vehicle networking information carried by the data packet. The data packet is a data packet carrying an IP packet header. The receiving device for performing networking information interaction with the sending device can be a base station, a roadside unit or a UE adjacent to the sending device, and the sending device can conveniently identify which receiving device is qualified to receive the data packet by setting the IP address to be in a corresponding form.

In the foregoing solution, when the data packet is assembled into the MAC PDU, before the target identification field in the MAC subheader is set as the roadside unit identification, the sending device initiates discovery of a roadside unit RSU, acquires the device identification corresponding to the RSU, and takes the acquired device identification as the roadside unit identification.

Step 102: and transmitting the identified data packet.

Here, the data packet identified with the car networking information may be mapped to a preset car networking bearer or a car networking logical channel for transmission; data packets that have been typed as being of the vehicle networking information type may also be communicated via a cellular network or device-to-device D2D communication.

Prior to sending the identified data packet, the method further comprises: the method comprises the steps that a sending device obtains the Internet of vehicles configuration information of the sending device; according to the configuration information of the Internet of vehicles, configuring Internet of vehicles transmission; and transmitting the identified data packet by using the configuration. The sending device can receive the base station, the ProSe Function from the terminal to the terminal D2D network element, or the car networking configuration information sent by the car networking functional entity; or, reading the car networking configuration information from a universal integrated circuit card UICC or a subscriber identity module card SIM card which is built in the car networking configuration information. Wherein, car networking configuration information includes at least: the vehicle networking support indication and the vehicle networking information transmission resource pool; the car networking support indication indicates which resource blocks RB on which subframe are used to transmit car networking information for the current UE1 and neighboring UEs in the same or different frequency serving cell from the current UE1, indicating that transmission of car networking information is supported. In addition, if a scheduling assignment rule is adopted, the car networking configuration information may further include at least one of: the system comprises a vehicle networking air interface network temporary identifier, a vehicle networking multicast/broadcast service air interface network temporary identifier, a modulation coding mode, a vehicle networking bearer configuration, a vehicle networking information transmission maximum transmission power, a roadside unit identifier or a roadside unit broadcast/multicast identifier or a vehicle networking multicast/broadcast identifier, vehicle networking multicast/broadcast identifiers respectively corresponding to vehicle networking information types, IP addresses of base stations/roadside units, vehicle networking multicast/broadcast IP addresses, vehicle networking port numbers of the base stations/roadside units, vehicle networking multicast/broadcast port numbers and multicast IP addresses corresponding to the vehicle networking information types. For the sending equipment, the vehicle networking information transmission resource pool is a sending resource pool; for the receiving device, the vehicle networking information transmission resource pool is a receiving resource pool.

In this embodiment, the car networking bearer configuration further includes at least one of: carrying an identifier; bearer types, which may include PC5 bearer or Uu bearer types; a logical channel identification; a logical channel group identification; a priority; a priority bit rate; a bucket size duration; a periodic buffer status reporting timer; a retransmission buffer status reporting timer; a sequence number field size; a rearrangement timer; a discard timer; a maximum connection identifier; a compression algorithm; PDCP sequence number size; whether it is encrypted.

If the car networking configuration information is not configured before the sending device and the receiving device send or receive the car networking information, the sending device and the receiving device also need to send car networking configuration request information to the base station to request transmission resources for car networking information interaction, and the car networking information can be smoothly interacted under the condition that the car networking configuration information is configured. Wherein the Internet of vehicles configuration request information comprises at least one of: the vehicle networking information sends and/or receives interest indications; the type of internet of vehicle service/application/information of interest; a priority of the car networking service/car networking application/car networking information; a request for establishing a vehicle networking bearer/logical channel; the information transmission range of the Internet of vehicles; sending the expected car networking information transmission range of the equipment; a vehicle networking information sending period; the quantity of resources required by the Internet of vehicles information transmission; sending a device mobile level; sending an IP address of the device; and sending the vehicle networking application port number of the device.

In addition, before a sending device such as a UE sends the Internet of vehicles configuration request information to a base station, if the UE is in an idle state and receives an Internet of vehicles information sending resource pool broadcasted by the base station, the UE can send the Internet of vehicles information to adjacent UEs and/or roadside units through a PC5 interface;

if the UE is in an idle state and only receives the vehicle networking support indication broadcasted by the base station and does not receive the vehicle networking information sending resource pool, the UE enters a connected state and sends vehicle networking configuration request information to the base station so as to request the base station to allocate a transmission resource block for the UE.

Fig. 2 is a schematic flow chart of an implementation of the internet of vehicles information transmission method applied to a receiving device according to the embodiment of the present invention; as shown in fig. 2, the method includes:

step 201: receiving a data packet, wherein the data packet is identified as the Internet of vehicles information;

here, the receiving device receives the car networking information sent by the sending device by using configured car networking configuration information such as a receiving resource pool.

Step 202: analyzing the data packet;

here, the receiving apparatus is at least one of a terminal UE, a roadside unit, and a base station; since the data packet carrying the car networking information is already identified in the sending device as described above, in this step, the receiving device needs to parse the data packet.

Step 203: and delivering the Internet of vehicles information according to the analysis result of the data packet.

Specifically, when the UE or the roadside unit detects that a PDU type field of a PDCP subheader of a 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 an Internet of vehicles protocol layer; and/or the presence of a gas in the gas,

when a roadside unit detects that a target identification field in an MAC subheader of a received data packet is a roadside unit broadcast identification or the roadside unit identification, the roadside unit delivers the data packet to a high-level Internet of vehicles; and/or the presence of a gas in the gas,

when a roadside unit detects that a target identification field in an MAC subheader of a received data packet corresponds to a roadside unit multicast identification and the roadside unit belongs to a corresponding roadside unit multicast group, the roadside unit delivers the data packet to a high-level Internet of vehicles; and/or the presence of a gas in the gas,

when the UE or the roadside unit detects that a target identification field in an MAC subheader of a received data packet corresponds to a multicast or broadcast identification corresponding to the type of the vehicle networking information interested by the UE or the roadside unit, the UE or the roadside unit delivers the data packet to a vehicle networking upper layer; and/or the presence of a gas in the gas,

when the base station, the roadside unit or the UE detects that the received data packet is a data packet transmitted on a vehicle networking bearer or a vehicle networking logical channel, the base station, the roadside unit or the UE delivers the data packet to a vehicle networking protocol layer; and/or the presence of a gas in the gas,

Therefore, the receiving equipment identifies that the data packet is a data packet carrying the car networking information through analyzing the PDU type field of the PDCP subheader of the data packet and the destination IP address carried by the data packet, directly delivers the data packet to the protocol layer or the upper layer of the car networking, and prevents the car networking information from being delivered to the core network.

UE1 and UE2 may be in a UMTS terrestrial radio Access network E-UTRAN network coverage state and the E-UTRAN network supports car networking functionality. In the presence of network coverage, the UE1 and the UE2 may obtain the car networking configuration information from the base station in advance to obtain transmission resources for each transmitting the car networking information. It is also possible that the UE1 and UE2 are in a state without network coverage, in which case, the UE1 and UE2 may use the car networking configuration information that is pre-saved on the respective UICC or SIM, or obtain the configured car networking configuration information from the ProSe Function or car networking Function entity.

In this application scenario, the UE1 detects that there is a safety function abnormality in the vehicle a, and it is desirable to send an out-of-control warning message to the vehicles around the UE. The application layer of the vehicle networking UE1 generates a vehicle networking message of the runaway warning information, the access layer of the UE1 packages the message into a data packet after receiving the message from the application layer, and the UE1 identifies the vehicle networking message with the data packet; specifically, in the PDCP layer of the UE1, the UE1 assembles the data packet into a PDCP PDU form, and sets a PDU type field of the PDCP subheader to an information type or a protocol type related to the car networking, so as to identify the data packet as a data packet carrying car networking information. At the MAC layer of UE1, UE1 assembles the packets into MAC PDUs and sets the target identification field in the MAC subheader to a broadcast identification or an internet of vehicles broadcast identification; of course, the target identification field in the MAC subheader may also be set to the broadcast identification corresponding to the runaway warning message. Then, the UE1 sends out the data packet carrying the runaway warning information through the PC5 interface using the car networking configuration information known in advance, such as the car networking information sending resource pool.

The vehicle networking UE2 adjacent to the UE1 monitors a vehicle networking information receiving resource pool known in advance, when the UE1 monitors a data packet sent through a PC5 interface, a target identification field in a MAC subheader is detected, and if the field is detected to be a broadcast identification, a vehicle networking broadcast identification or a broadcast identification corresponding to an out-of-control warning message interested by the UE2, the UE2 delivers the data packet to an RLC layer and a PDCP layer of the UE2 for further analysis. At the PDCP layer, if the UE2 detects that the PDU type field of the PDCP subheader of the packet is an information type or protocol type related to the car networking, the UE2 delivers the packet to the car networking application layer/upper layer without being processed by the IP layer. After receiving the runaway warning message, the application layer of the UE2 further determines whether the event is associated with the vehicle in which the UE2 is installed and, if so, alerts the driver of the UE 2. In the long term evolution LTE system, the protocol layers include: PDCP, Radio Link Control (RLC), and MAC layers. The application scenario 1 can be seen in fig. 3(d) and fig. 4.

Application scenario 2:

the vehicles a and B are respectively equipped with a UE1, a UE2 having a car networking function. The UE1 and the UE2 are in an E-UTRAN network coverage state, and the E-UTRAN network supports the car networking function. When the vehicle A with the UE1 suddenly brakes and stops in the middle of the road, the application layer of the UE1 generates a warning vehicle alarm DENM message, which is expected to be sent to the vehicles around the UE.

When the UE1 is in the idle state and only receives the vehicle networking support indication information and/or the vehicle networking information receiving resource pool broadcasted by the base station, but does not receive the vehicle networking information sending resource pool, the UE1 enters the connected state from the idle state, and sends the vehicle networking configuration request information to the base station, where the request information may include an indication of vehicle networking information sending and/or receiving interest, a vehicle networking service/application/information type of interest to the UE1, and the like. After receiving the configuration request message, the base station sends the vehicle networking configuration message, such as the vehicle networking message sending resource pool, to the UE 1.

After receiving the car networking configuration information sent by the base station, the UE1 configures according to the car networking configuration information and packs a warning vehicle warning DENM message into a data packet. When the UE1 assembles the data packet into a PDCP PDU, setting a PDU type field of a PDCP subheader as an information type or a protocol type related to the Internet of vehicles; when the data packets are assembled into MAC PDU, the target identification field in the MAC subheader is set as a broadcast identification or a vehicle networking broadcast identification so as to identify the data packets as the data packets carrying vehicle networking information. The UE1 uses the vehicle networking information transmission resource pool allocated by the base station to send out DENM message carrying the warning vehicle warning through the PC5 interface.

The vehicle networking UE2 adjacent to the UE1 monitors the vehicle networking information receiving resource pool allocated by the base station, when the UE 3526 monitors the data packet sent by the UE1 through the PC5 interface, the target identification field in the MAC subheader is detected first, and if the field is detected to be the broadcast identification or the vehicle networking broadcast identification, the UE2 delivers the data packet to the RLC layer and the PDCP layer of the UE2 for further analysis. When the PDCP layer detects that the PDU type field of the PDCP subheader of the data packet is the information type or the protocol type related to the Internet of vehicles, the UE2 delivers the data packet to the Internet of vehicles application layer/higher layer. After receiving the warning vehicle alarm DENM message, the car networking application layer of the UE2 further determines whether the event is related to the vehicle in which the UE2 is installed and, if so, issues a warning to the driver of the UE 2. The foregoing description should be understood in conjunction with the internet of vehicle architecture fig. 3(d) and fig. 5.

In this embodiment, for the car networking configuration request of the UE1, the base station may also configure different car networking information sending and/or receiving resource pools for different supported car networking information/services/application types; the UE1 may also be configured with only a vehicle networking information transmission and/or reception resource pool corresponding to the vehicle networking services/applications/information types of interest to the UE 1; the UE1 may also be configured to send and/or receive resource pool information for the internet of vehicles of neighboring cells, which may be cells with the same frequency and/or different frequencies from the serving cell to which the UE1 belongs. If the base station desires the UE1 to adopt scheduling resource allocation, the base station may configure an air interface network temporary identifier, a modulation and coding scheme, a multicast/broadcast identifier for the vehicle networking, and the like for the UE1 to schedule the vehicle networking transmission resource. The specific configuration of the base station to the UE is flexibly set according to the actual situation, and is not described in detail here.

Application scenario 3:

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

After receiving the configuration request information, the RSU serving as the base station sends car networking configuration information to the UE1, where the configuration information includes car networking air interface network temporary identifiers, car networking multicast/broadcast service air interface network temporary identifiers, modulation and coding modes, car networking bearer configurations, car networking multicast/broadcast identifiers corresponding to various car networking information types, and the like; where the content included in the car networking bearer configuration please refer to the related description above. Preferably, the base station may configure a plurality of car networking bearers for the UE1 according to the type of car networking information of interest to the UE and the priority, and send the car networking configuration information to the UE 1.

After receiving the car networking configuration information sent by the base station, the UE1 performs car networking bearer configuration according to the car networking configuration information, then packs the automatic parking request information generated by the car networking high layer of the UE1 into a data packet, sets the logical channel identification field of the MAC subheader as a car networking logical channel identification, and maps the data packet carrying the automatic parking request information onto a car networking bearer or a car networking logical channel; finally, the UE1 uses the uplink cellular network resources to send data packets carrying the automatic parking request information to the serving cell.

And the service cell receives the data packet, detects that the data packet is transmitted through the vehicle networking bearer according to the logical channel identification field of the MAC layer, and delivers the data packet to the RSU. The RSU, upon receiving the automatic parking request message, authenticates the message, determines whether the UE1 can be allowed to enter parking and if permitted to pass, informs vehicle a that it can enter the parking lot to park. This application scenario can be understood in conjunction with fig. 3(a) and fig. 6. In this application scenario, the RSU may be served by the base station, and may further be served by the UE as the car networking architecture diagrams 3(b) and 3 (c).

In the foregoing application scenarios 1 to 3, under the condition that the data packet carrying the car networking information does not carry an IP packet header, processing by an IP layer of the UE2/RSU is not required, and processing resources are saved. Meanwhile, the data packet is identified to be the data packet carrying the Internet of vehicles information through a corresponding field or a special Internet of vehicles bearing, and the method is simple and easy to implement and high in transportability. In addition, the data packet carrying the car networking information is determined to be delivered to a protocol layer or a high layer of the car networking through analyzing a target identification field in an MAC sub-header, a PDU type field of a PDCP sub-header and a logic channel identification field of an MAC layer in the data packet, and the diffusion of the car networking information to a core network is avoided.

Application scenario 4:

the vehicles a and B are respectively equipped with a UE1, a UE2 having a car networking function. The UE1 and the UE2 are in an E-UTRAN network coverage state, and the E-UTRAN network supports the car networking function. When the vehicle A with the UE1 suddenly brakes and stops in the middle of the road, the Internet of vehicles application layer of the UE1 generates a warning vehicle alarm DENM message, and the warning vehicle alarm DENM message is hopefully sent to the vehicles around the warning vehicle alarm DENM message.

Assuming that the UE1 is in the idle state, and only receives the vehicle networking support indication information and/or the vehicle networking information receiving resource pool broadcasted by the base station, but does not receive the vehicle networking information sending resource pool, the UE1 enters the connected state and sends the vehicle networking configuration request information to the base station, where the request information may include the vehicle networking information sending and/or receiving interest indication, the vehicle networking service/application/information type interested by the UE1, the priority of the vehicle networking information, and the like. In addition, the UE1 may send information on reporting the status of the car networking buffer to the base station, where the information carries a logical channel group identifier corresponding to a car networking bearer, and after receiving the report, the base station schedules a car networking information sending resource pool for the UE1, and issues the allocated resource through a car networking air interface network temporary identifier.

After receiving the car networking configuration information sent by the base station, the UE1 configures according to the car networking configuration information, packs the DENM message for warning the car alarm into a data packet, sets a target identification field in an MAC subheader as a car networking multicast/broadcast identification when the data packet is assembled into an MAC PDU (media access control protocol data Unit), and configures a target IP address of the data packet as a broadcast address, wherein the data packet carries an IP packet header. The UE1 then sends out a warning vehicle alert DENM message over the PC5 interface using the vehicle networking information send resource pool obtained from the base station.

When the neighboring vehicular UE2 monitors the data packet sent by the UE1 through the PC5 interface through the vehicular networking information receiving resource pool allocated by the base station, the target identification field in the MAC subheader is determined, and if the target identification field is the vehicular networking multicast/broadcast identification, the UE2 delivers the data packet to the higher layer/application layer of the UE2 for subsequent processing. After receiving the warning vehicle alarm DENM message, the higher Internet of vehicles layer/application layer of the UE2 further determines whether the event is related to the vehicle in which the UE2 is installed and, if so, issues a warning to the driver. For an understanding of this application scenario, see the aforementioned car networking architecture fig. 3(d) and fig. 7.

In this embodiment, the base station may also configure different vehicle networking information sending and/or receiving resource pools for different supported vehicle networking information/services/application types, or may also configure only a vehicle networking information sending and/or receiving resource pool corresponding to a vehicle networking service/application/information type in which the UE1 is interested for the UE 1; the UE1 may also be configured to send and/or receive resource pool information for the internet of vehicles of neighboring cells, which may be cells with the same frequency and/or different frequencies from the serving cell in which the UE1 is located. If the base station desires the UE1 to adopt scheduling resource allocation, the base station may configure an air interface network temporary identifier, a modulation and coding scheme, a multicast/broadcast identifier for the vehicle networking, and the like for the UE1 to schedule the vehicle networking transmission resource. The specific configuration situation is flexibly set according to the actual application situation.

Application scenario 5:

vehicle a installs a UE1 with car networking capability. The vehicle in which the UE1 is installed wishes to send detected road safety information to the RSU. The RSU is served by UEs or small cells deployed beside the highway. When vehicle a wants to report road safety information, UE1 initiates RSU discovery, and assuming that UE1 detects that the RSU broadcast by nearby UEs or base stations has RSU support indication, UE1 may send a vehicle networking configuration request to the RSU, which may include vehicle networking service/application/information type that the vehicle networking information sending interest indication is interested in, and IP address of UE1, etc.

After receiving the configuration request, the RSU, which is the UE or the base station, sends the car networking configuration information to the UE1, where the configuration information includes the car networking bearer, the IP address and the port number of the RSU. Please refer to the foregoing description for the content carried by the internet of vehicles. The in-vehicle UE and the RSU can find each other by the IP address of the other side (the IP address of the UE1 and the IP address and port number of the RSU) when they realize unicast communication. In addition, the RSU that the UE or base station acts as may configure multiple car networking bearers for the UE1 according to the type of car networking information of interest to the UE and the priority, and send the car networking configuration information to the UE 1.

After receiving the vehicle networking configuration information sent by the RSU served by the UE or the base station, the UE1 performs vehicle networking bearer configuration according to the vehicle networking configuration information, packages road safety information generated by a high-level vehicle networking layer of the UE1 into a data packet, sets a logical channel identification field of the MAC subheader as a vehicle networking bearer identification or a vehicle networking logical channel identification, and maps the data packet to the vehicle networking bearer or the vehicle networking logical channel. Finally, the UE1 uses the PC5 interface (UE acting as RSU) or Uu interface (base station acting as RSU) to send the data packet carrying the road safety information to the UE or RSU that the base station acts as.

After receiving the message, the RSU acting as the UE or the base station detects that the data packet is transmitted through the car networking bearer or the logical channel according to the logical channel identification field of the MAC layer, and then the RSU delivers the data packet to the higher layer/application layer. For an understanding of this application scenario, refer to fig. 3(a), (b), (c) and fig. 8.

Application scenario 6:

vehicle a installs a UE1 with car networking capability. The vehicle in which the UE1 is installed has joined the fleet of platooned vehicles and wishes to report this information to a nearby RSU. The RSU is served by a base station deployed beside the highway. When the vehicle a wants to report the formation driving information, the UE1 first initiates RSU discovery, and when detecting an RSU support indication broadcast by an RSU served by a nearby UE, the UE1 transmits to the RSU vehicle networking configuration request information including a vehicle networking information transmission interest indication, an IP address and port number of the UE1, and the like. Here, the IP address and port number of the sending UE1 are to enable the internet protocol transceivers to find each other according to the address and port number provided by the other party when implementing unicast.

After receiving the configuration request information, the RSU acting as the base station sends car networking configuration information to the UE1, where the information at least includes an IP address and a port number of the RSU. After receiving the vehicle networking configuration information sent by the RSU served by the UE or the base station, the UE1 reports the IP address and the port number information of the RSU to the higher layer of the vehicle networking. The high-level of the vehicle networking of the UE1 generates formation driving reporting information, packages the information into a data packet, configures the target address and the port number of the IP packet header as the target address and the port number of the RSU respectively, and maps the data packet to the cellular bearer. Finally, the UE1 sends the data packet carrying the formation driving reporting information to the RSU served by the base station using the uplink cellular resource of the Uu interface.

After receiving the data packet, the RSU acting as the base station detects an IP packet header of the data packet, and if it is detected that a target address in the IP packet header is an address of the RSU, the base station delivers the data packet to an application layer of the RSU having the address. For an understanding of this application scenario, refer to fig. 3(a) and 9.

In the foregoing application scenarios 4 to 6, the data packet carrying the car networking information carries an IP packet header, and the data packet is mapped onto a dedicated bearer channel or a cellular bearer that is obtained in advance by both communication parties, so as to identify the data packet as a data packet carrying the car networking information, and a target address in the IP packet header is used to obtain a receiving device capable of receiving the car networking information. The method is simple and easy to implement and has strong transportability. In addition, the data packet carrying the car networking information is determined to be delivered to a protocol layer or a high layer, and the diffusion of the car networking information to a core network is avoided.

According to the scheme, the transmission standard of the vehicle networking information in the V2X mode is provided, the standard is simple and easy to implement, strong in portability and suitable for different communication systems such as Long Term Evolution (LTE), enhanced-access network (E-UTRAN) and the like.
