Description
Technical field
The present invention relates to the communications field, in particular to a kind of car networking information transferring method, apparatus and system.
Background technology
With the development of wireless multimedia service, people are growing to the demand of high data rate and Consumer's Experience, thus
High requirement is proposed to the power system capacity and covering of conventional cellular network.Another aspect public safety, social networkies, near
Range data is shared, the application scenarios such as local advertising make that people are right to be desorbed nearly persons or thingses and communicate
The demand of (Proximity Services, adjacent service) is gradually increased.Traditional cellular network centered on base station exists
There is obvious limitation in the support aspect of high data rate and adjacent service, under this requirement background, represent future
Device-to-device (Device-to-Device, the referred to as D2D) technology of development communication technologies new direction is arisen at the historic moment.
The application of D2D technology, the burden that cellular network can be mitigated, the battery power consumption reducing user equipment, raising data rate,
And improve the robustness of network infrastructure, meet the requirement of above-mentioned high data rate traffic and adjacent service well.
D2D technology can be operated in mandate frequency range or unauthorized frequency range it is allowed to the user equipment of multiple support D2D function,
I.e. D2D user equipment (D2D User Equipment, referred to as D2D UE) is having network infrastructure or no network
/ direction communication is directly found in the case of infrastructure.Fig. 1 is the application model of the D2D according to correlation technique
Schematic diagram, as shown in figure 1, the application scenarios of D2D mainly have three kinds：
1.UE1 and UE2 carries out data interaction under the covering of cellular network, and user face data sets without network foundation
Apply, such as the pattern 1 of Fig. 1；
2., in the UE relay transmission of weak/no overlay area, pattern 2 in such as Fig. 1 is it is allowed to the poor UE4 of signal quality
Communicated with network by the UE3 nearby having the network coverage, operator can be helped to spread over, improve capacity；
3. there is earthquake or emergency, it is allowed to equipment room directly leads in the case of cellular network cisco unity malfunction
Pattern 3 in letter, such as Fig. 1, between UE5, UE6 and UE7, chain of command and user plane are all without network infrastructure
Carry out a jump or the data communication of multi-hop.
D2D technology generally includes D2D discovery technique and D2D communication technology, and wherein, D2D discovery technique refers to use
In judging/determine first user equipment whether adjacent to the technology of second user equipment.Generally, can lead between D2D user equipment
Cross transmission or reception finds signal/information to find other side；D2D communication technology refer between D2D user equipment part or
The technology that all communication data directly can not be communicated by network infrastructure.
On the other hand, with economic society high speed development, China's automobile guarantee-quantity increases rapidly, and road traffic accident is frequent
Occur, it has also become one of key factor of the China of impact in recent years public security perception, traffic safety problem has become as
One of impact social harmony and the basic problem that improves People's livelihood.China is in the urgent need to from each side such as technology, policy, education
Improve traffic safety, wherein the design of lifting vehicle safety is important component part therein.The technology master of lifting vehicle safety
It is divided into passive security technology and active safety technologies.Passive security technology is used for after accident occurs, to outside in-car, car
Personnel and the protection of article；Active safety technologies are used for preventing and reduce vehicle and have an accident, it is to avoid personnel come to harm；
Active safety technologies are emphasis and the trend that car networking technology is the development of modern vehicle safe practice.
Above feature based on D2D technology and advantage, correlation technique has been proposed that using cellular radio Communication and D2D
Technology, to realize the possibility of car networking application, supports that the prevailing scenario of communication includes instant messaging and two aspects of vehicle early warning.
Based on the car networking system of D2D/ cellular communication, by using advanced radio honeycomb communication technology, realize car and car,
Real-time information interaction between car and trackside infrastructure, inform current each other state (include the position of vehicle, speed,
Acceleration, driving path) and the road environment information known, collaborative sensing road hazard condition, multiple touching is provided in time
Hit early warning information, prevent the generation of traffic safety accident, become current various countries and attempt solving road traffic safety problem
A kind of new thinking.
The pattern of car networking communication is specifically divided into three kinds：Truck traffic (Vehicle-to-Vehicle Communications,
Referred to as V2V), car Network Communication (Vehicle-to-Infrastructure Communications, referred to as V2I), car people
Communicate (Vehicle-to-Pedestrian Communications, referred to as V2P) three classes, and this three class can also be referred to as
Communicate (Vehicle-to-Everything Communications, referred to as V2X) for car networking.Wherein V2I is as V2X
One kind of service, it is the UE and roadside unit (Road Side Unit, referred to as RSU) using V2I application program
Between communication.Wherein RSU is the entity supporting V2I service, can receive number from the UE using V2I application program
According to or send data to the UE using V2I application program.
RSU can be realized by base station or static UE.The function of RSU mainly includes following：1) periodically send V2I
Broadcast gives neighbouring Vehicle UE；2) receive the V2I message from Vehicle UE, then broadcast corresponding
V2I message；3) carry out One-to-one communication with Vehicle UE；4) it is connected and communicates with traffic safety service device.But it is existing
Have technology not yet can solve the problems, such as need on a large scale under interior broadcast V2I message scene information transfer.
For in correlation technique, the transmission problem of interior car networking information, there is presently no effective solution on a large scale.
