With the popularization of automobile, traffic safety problem has become as impact social harmony and improves People's livelihood One of basic problem, need to improve traffic safety from each side such as technology, policy, education, wherein carry Rise the important component part that vehicle safety design is solving road traffic safety problem.Wherein, lift vehicle The technology of safety is broadly divided into passive security technology and active safety technologies, and passive security technology is used in thing Therefore after occurring, the protection of outer personnel and article to in-car, car；Active safety technologies are used for preventing and reduce Vehicle has an accident, it is to avoid personnel come to harm；Active safety technologies are the development of modern vehicle safe practice Emphasis and trend.For example, the investigation report according to National Highway Traffic safety management bureau shows Show, 80% road traffic accident is because driver occurs the carelessness in first 3 seconds to cause in accident, One experiment of Daimler-Benz shows, if driver can shift to an earlier date 0.5 second driver that warns, can To avoid 60% rear-end collision, if driver can be shifted to an earlier date 1.5 seconds and being warned and taken measures, 90% car accident that knocks into the back can be avoided.Therefore, the collision warning systems based on communication, by using Radio honeycomb communication technology, to realize the real time information between vehicle and vehicle, vehicle and trackside infrastructure Interaction, informs state current each other, for example, include the position of vehicle, speed, acceleration, travel road Footpath, and the road environment information known, collaborative sensing road hazard condition, multiple collisions are provided in time Early warning information, reduces and prevents the generation of traffic safety accident, becomes current solving road traffic peace A kind of new thinking of full problem.
With the development of wireless multimedia service, people are to high data rate and Consumer's Experience demand increasingly Increase, the power system capacity to conventional cellular network and covering propose high requirement, on the other hand public peace Entirely, social networkies, closely the application scenarios such as data sharing, local advertising make people right solution near Persons or thingses, and the demand of (Proximity Services, adjacent service) that communicates is gradually increased. Therefore, traditional cellular network centered on BS is in the support side of high data rate and adjacent service There is obvious limitation in face, and device-to-device (Device-to-Device, referred to as：D2D) technology Become the important way solving the above problems, the application of D2D technology, can mitigate cellular network burden, Reduce the battery power consumption of user equipment, improve data rate, and improve the robustness of network infrastructure, Meet the requirement of above-mentioned high data rate traffic and adjacent service well.
Specifically, D2D technology generally includes D2D discovery technique and D2D communication technology, wherein, D2D Discovery technique refer to for judge/determine first user equipment (User Equipment, referred to as：UE) Whether adjacent to the technology of the 2nd UE；Support the user equipment of D2D function, as D2D user equipment (D2D User Equipment, referred to as：D2D UE), by sending or can receive between D2D UE The mode finding signal/information is finding other side；D2D communication technology refers to part or complete between D2D UE The technology that portion's communication data directly can not be communicated by network infrastructure.D2D technology is usual Can be operated in mandate frequency range or unauthorized frequency range it is allowed to multiple D2D UE have network infrastructure or No directly found/direction communication in the case of network infrastructure.Realization to D2D technology below Mode is done with brief description, as shown in figure 1, the application scenarios schematic diagram communicating for D2D in prior art, Network infrastructure in Fig. 1 with evolved base station (evolved Node B, referred to as：ENB as a example) Illustrated, the application scenarios of D2D communication mainly have three kinds：
1), UE1 and UE2 carries out data interaction under the covering of cellular network, user face data without Cross eNB, the pattern 1 in such as Fig. 1；
2), eNB cover weaker region or the region that is not covered with, UE carries out relay transmission, As the pattern 2 in Fig. 1 it is allowed to the poor UE4 of signal quality passes through the UE3 nearby having eNB to cover Communicated with eNB, operator can be helped to spread over, improve capacity；
3) there is earthquake or emergency, it is allowed to equipment in the case of cellular network cisco unity malfunction Between direction communication, the pattern 3, UE5 in such as Fig. 1, the chain of command between UE6 and UE7 and user plane are all Carry out a jump or the data communication of multi-hop without eNB.
Above feature based on D2D technology and advantage, prior art has been proposed that and uses cellular radio Communication And D2D communicates and to realize the application of car networking, the prevailing scenario of communication includes instant messaging and vehicle is pre- Alert two aspects, vehicle early warning may include anti-collision warning, lane change early warning etc., but right under this scene The requirement of time delay is very high, and existing D2D technology is between vehicle and vehicle, or vehicle and the network equipment Between communicated before need to carry out D2D discovery it is impossible to meet requirement to time delay.
In car networking communication, and vehicle and vehicle under many scenes (Vehicle to Vehicle, referred to as： V2V) communication needs to meet low time delay and highly reliable index request, as shown in Fig. 2 being prior art A kind of application scenarios schematic diagram of middle vehicular traffic, as shown in figure 3, communicate for car networking in prior art A kind of application scenarios schematic diagram, distance between two cars, for example：Vehicle A and vehicle B is too near, needs It is noted that the traffic safety between vehicle, if vehicle A first by the information such as the position/speed of its own report to The network equipment, then vehicle B is notified by the network equipment, then vehicle B obtains position/speed of vehicle A etc. Information has higher time delay, and vehicle B can be led to cannot to avoid rapidly A, car.It should be noted that In car networking communication, the communication between above-mentioned vehicle and the network equipment is referred to as V2I and communicates, and V2I communicates Can communicate for V2R, the network equipment in V2R communication is roadside equipment (Radio Side Unit, letter Referred to as：RSU), V2I communication and V2R communicate and just refer to vehicle and the communication of LA Management Room, this net Network equipment can be for example：ENB, Infrastructure, RSU, and relaying (relay) etc..
Therefore, under the above-mentioned application scenarios related to vehicle safety, in prior art, generally adopt V2V Communication, V2V communication can adopt third generation partner program (3rd Generation Partnership Project, referred to as：Above-mentioned D2D technology defined in 3GPP).In order to realize V2V communication, often Support that the vehicle of V2V communication is required for obtaining communication required resource, the frequency of such as communication and time slot Deng physical resource, when V2V communication is using D2D technology defined in 3GPP, V2V communication institute The resource needing can be obtained in the way of using competition, the first use for example first obtaining, but this mode may Under the region more than vehicle, produce resource congestion and collision.For example：One piece is had to allocate in advance Resource Block, but multiple vehicle is all using identical resource, typically identical frequency resource and time slot Resource, then can lead to these vehicles all cannot use this resource, so that the information of these vehicles is all no Method sends.Therefore, in V2V communication, if vehicle is obtained in resource pool by the way of competition Resource is it is easy to producing collision and leading to information of vehicles can not send in time.Based on above reason, In a region, if vehicle is relatively more, lead to congestion in order to avoid these vehicle competitive resources, Can be the distribution of each vehicle and scheduling resource by network.
However, the implementation of car networking of the prior art communication, each vehicle is independent as one Individuality, car networking communication is actual to be between vehicle and vehicle, and carry out between vehicle and the network equipment Communicate two-by-two, interactive information is more frequent, and need interactive data volume larger, thus causing car to join The problems such as management complexity of net is higher.
Face is described in detail to technical scheme by specific embodiment, and the present invention is following Vehicle in embodiment be can support D2D communication vehicle, for example, above-mentioned D2D UE, and V2V communication in various embodiments of the present invention all taking using D2D technology defined in 3GPP as a example gives Illustrate, now the air interface between vehicle and vehicle adopts the PC5 defined in 3GPP D2D technology Interface, V2I communication can adopt the air interface between vehicle and the network equipment defined in 3GPP, I.e. Uu interface (User Equipment/ user equipment).The network equipment in various embodiments of the present invention is Finger can provide and distribute car networking resource, control and management car networking business, and/or can be car networking Business provides the gateway logic unit of wireless access, and this network equipment for example can include eNB, relaying and RSU, when the network equipment is eNB, or Relay, or when comprising the RSU of eNB function, vehicle The communication and network equipment between can adopt V2I pattern, realizes by Uu interface communicating to connect Foundation, this Uu interface is exactly the interface between eNB and UE in 3GPP；When the network equipment is bag When RSU containing UE function, the communication between vehicle and the network equipment can adopt V2V pattern, Realized by PC5 interface, this PC5 interface is exactly in 3GPP D2D technology between UE and UE Interface.The present invention provides following specific embodiment can be combined with each other, for same or similar Concept or process may repeat no more in some embodiments.
