The investigation report of National Highway Traffic safety management office shows, the road traffic accident of 80% be due to
Driver's carelessness in accident occurs first 3 seconds causes.One experiment of Daimler-Benz shows,
If 0.5 second driver that warns in advance, the rear-end collision of 60% can be avoided；If driver can do sth. in advance 1.5 seconds
Warned and taken measures, then can be avoided the car accident that knocks into the back of 90%.Anti-collision warning based on communication
System, by utilizing advanced radio honeycomb communication technology, it is achieved between Che Yuche, car and trackside infrastructure
Real-time information interaction, informs that the most current state (includes the position of vehicle, speed, acceleration, traveling road
Footpath) and the road environment information known, collaborative sensing road hazard condition, multiple anti-collision warning letter is provided in time
Breath, prevents the generation of traffic safety accident, becomes current various countries and attempt solving road traffic safety problem
A kind of new thinking.
Meanwhile, along with the development of wireless multimedia service, people's demand day to high data rate and Consumer's Experience
Benefit increases, thus the power system capacity and covering to conventional cellular network proposes high requirement.The most public
Safety, social networks, the closely application scenarios such as data sharing, local advertising make that people are right desorbs person of modern times
Or things communicate the demand of adjacent service (Proximity Services, referred to as PS) and be gradually increased.
Traditional cellular network centered by base station exists bright in terms of the support of high data rate and adjacent service
Aobvious limitation, under this requirement background, represents the device-to-device of future communication technologies development new direction
(Device-to-Device, referred to as D2D) technology is arisen at the historic moment.The application of D2D technology, can alleviate
The burden of cellular network, reduce the battery power consumption of subscriber equipment, improve data rate, and improve network foundation and set
The robustness executed, meets 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 use of multiple support D2D functions
Family equipment, i.e. D2D subscriber equipment (D2D User Equipment, referred to as D2D UE) is having network base
Infrastructure or without directly finding in the case of network infrastructure/directly communicating.
Fig. 1 is the application scenarios schematic diagram of D2D technology in correlation technique, as it is shown in figure 1, the application of D2D
Scene includes three kinds, and pattern 1:UE1 and UE2 carry out data interaction under the covering of cellular network, uses
Face, family data are without network infrastructure；Pattern 2: weak/without the UE relay transmission of overlay area, it is allowed to
The poor UE4 of signal quality has the UE3 of the network coverage to communicate with network near passing through, and can help operation
Business spreads over, improves capacity；Pattern 3: earthquake or emergency are occurring, cellular network can not normal work
In the case of work, it is allowed to equipment room directly communicates, between UE5, UE6 and UE7, chain of command and user face are the most not
The data communication of a jumping or multi-hop is carried out through network infrastructure.
D2D technology generally includes D2D discovery technique and D2D communication technology, wherein, D2D discovery technique

And D2D technology realizes the possibility of car working application, support that the prevailing scenario of communication includes instant messaging and car
Two aspects of early warning.Vehicle early warning may include anti-collision warning, lane change early warning etc., but right under this scene
The requirement of time delay is the highest, and existing D2D technology cannot realize.
In car connected network communication, communication between vehicle and vehicle under many scenes, it is also possible to be referred to as truck traffic
(vehicle to vehicle, referred to as V2V) needs to meet low time delay and highly reliable index request.Such as:
The spacing of two cars is too near, such as: car A and car B distance is too near, should be noted that the driving peace between car
Entirely.Fig. 2 is the schematic diagram of vehicular traffic in correlation technique, if as in figure 2 it is shown: car A is first by it certainly
The information such as the position/speed of body are reported to network, then by network advertisement car B, then car B obtain the position of car A/
The information such as speed have time delay, and car B can be caused cannot to dodge rapidly car A.
Fig. 3 is the schematic diagram of car connected network communication in correlation technique, as it is shown on figure 3, in car connected network communication, will
This car and internetwork communication are referred to as car, and to trackside infrastructure, (Vehicle to Infrastructure is referred to as
V2I).V2I communication also referred to as V2R communication, R is exactly roadside equipment (Radio Side unit, referred to as RSU),
V2I with V2R communicates and refers to Vehicle and internetwork communication, and network equipment may is that roadside equipment
RSU, evolution node eNB, relaying relay etc..
Therefore, under the application scenarios that these are relevant to vehicle safety, use V2V communication proper.Enter
One step ground, V2V communication can use above-mentioned D2D technology defined in 3GPP.In order to realize V2V communication,
Each supports that the vehicle of V2V communication is required for obtaining the resource needed for communication, such as: the frequency of communication and time
The physical resources such as gap, when V2V communication uses D2D technology defined in 3GPP time, V2V communication is required
The resource wanted can obtain, such as in the way of using competition: the first use first obtained, but this mode may be at vehicle
Under many regions, produce resource congestion and collision.As: there is one piece of Resource Block distributed in advance, but multiple car
All use identical resource, such as: identical frequency resource and time interval resource, these cars can be caused all cannot to make
Use this resource, so that the information of these cars all cannot send.So, in V2V communicates, as
Really vehicle uses the mode of competition to obtain resource in resource pool, it is easy to produces collision and causes the information of vehicles can not
Send in time.
Based on above reason, in a region, if vehicle is the most, in order to avoid these vehicles competition money
Source and cause congested, can be that each car distributes and scheduling resource by network, such V2V communication time,
Would not occur that multiple car uses the situation of same asset simultaneously, the information of each car can also send in time
Go out.Based on the problems referred to above, a kind of method proposing fleet management/control in correlation technique, it may be assumed that net
Network mandate fleet head obtains the control of fleet, and fleet's head is that the vehicle in fleet provides resource management, mobility
Management and connection management etc..But, owing to car networking is a dynamic mobile and the network being continually changing, due to
A variety of causes, car is suspended in such as headstock midway, or headstock drops by the wayside fleet etc. so that fleet loses car
Head, so that fleet's normal management causes confusion.
For when the headstock of fleet breaks down or leaves fleet in car networking in correlation technique, cause fleet management
The problem caused confusion, the most not yet proposes effective solution.
