Embodiment 1

[0139] The first optional embodiment is aimed at the scenario where the OBU sends information to the V2X AS through the V2X function; Figure 10 is a flow chart of a method according to an optional embodiment 1 of the present invention, such as Figure 10 As shown, the steps of this method include:

[0140] In step S1001, the OBU sends information to the V2X function.

[0141] Among them, the OBU sends information to the V2X function through the PC3 interface.

[0142] Step S1002, the V2X function sends information to the V2X AS.

[0143] Among them, the V2X function sends information to the V2X AS through the PC2 interface.

[0144] Step S1003, the V2X AS sends a response message to the V2X function.

[0145] Among them, the V2X AS determines whether to accept or reject the OBU information according to local information. If accepted, the V2X AS sends a success response message to the V2X function through the PC2 interface, and if rejected, the V2X AS sends a failure respo...

Embodiment 2

[0149] The second optional embodiment is aimed at the scenario where the OBU sends information to the V2X AS through application layer signaling; Figure 11 It is a flow chart of the method according to the second optional embodiment of the present invention, such as Figure 11 As shown, the steps of the method include:

[0150] Step S1101, OBU sends signaling to V2X AS through application layer signaling;

[0151] Among them, the OBU is in the RRC-connected connection state. If the OBU is in the RRC-idle idle state, the OBU first establishes an RRC connection; the OBU sends application layer signaling to the V2X AS through the 3GPP network or other transmission networks.

[0152] Step S1102, the V2X AS sends a response through application layer signaling.

[0153] Among them, the V2X AS receives the application layer signaling of the OBU from the VC1 interface, and the V2X AS sends a response message to the OBU through the application layer signaling through the 3GPP networ...

Embodiment 3

[0155] The third optional embodiment is for the scenario where the V2X AS sends data to the OBU; Figure 12 It is a flow chart of the method according to the third optional embodiment of the present invention, such as Figure 12 As shown, the steps of the method include:

[0156] Step S1201, judging whether to send data to the OBU through unicast, if so, turn to step S1202, otherwise turn to step S1203;

[0157] Among them, the V2X AS accepts the request information of the OBU and sends the required data to the OBU. The V2X AS can send data to the OBU in broadcast or unicast mode. The V2X AS determines whether to use unicast or Broadcast bearer to send data, if the network deploys MBMS broadcast bearer, and the target OBU has more than one and is in the adjacent area, and the service provider allows broadcast transmission, and the OBU has MBMS reception capability, then the V2X AS can use broadcast to send data, otherwise The V2X AS uses unicast to send data.

Abstract

The invention provides vehicle to everything architecture and a service realization method and device therein. The vehicle to everything architecture at least comprises a vehicle-mounted unit, a road side unit, a vehicle to everything function entity and a vehicle to everything application server. The method comprises the steps that the vehicle-mounted unit sends request information to the vehicle to everything application server via a network application layer signal or the vehicle to everything function entity, wherein the request information is used to indicate a request for vehicle to everything service; the vehicle-mounted unit receives first indication information of the vehicle to everything application server in response to the request information, wherein the first indication information is used to indicate that the request information succeeds or fails to request the vehicle to everything service; and when the first indication information indicates that the request information makes a successful request, the vehicle-mounted unit receives data of the vehicle to everything service sent by the vehicle to everything application server via the road side unit. Through application of the architecture, the method and the device, the problem in the relevant art that it is difficult for an RSU (Road Side Unit) to meet the current vehicle to everything service needs is solved, thereby achieving the effect of improving the efficiency of resource or service management in the vehicle to everything.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to an Internet of Vehicles framework and a service realization method and device therein. Background technique [0002] With the rapid economic and social development, China's car ownership has grown rapidly, and road traffic accidents have occurred frequently, which has become one of the important factors affecting the public's sense of security in recent years. Road traffic safety has become a basic issue affecting social harmony and improving people's livelihood one. China urgently needs to improve traffic safety in terms of technology, policy, education and other aspects, and improving vehicle safety design is an important part of it. [0003] Technologies to improve vehicle safety are mainly divided into passive safety technologies and active safety technologies. Passive safety technology is used to protect people and objects inside and outside the vehicle after...
