Description

车联网架构及其中的业务实现方法和装置 技术领域
本发明涉及通信领域，具体而言，涉及一种车联网架构及其中的业务实现方法和装置。
背景技术
随着经济社会高速发展，中国汽车保有量迅速增长，道路交通事故频繁发生，已成为近年来影响我国公众安全感的重要因素之一，道路交通安全问题已经成为影响社会和谐和改善民生的基本问题之一。中国迫切需要从技术、政策、教育等各方面改善交通安全，其中提升车辆安全设计是其中的重要组成部分。
提升车辆安全的技术主要分为被动安全技术和主动安全技术。被动安全技术用于在事故发生后，对车内、车外人员及物品的保护；主动安全技术用于防止和减少车辆发生事故，避免人员受到伤害；主动安全技术是现代车辆安全技术发展的重点和趋势。
基于通信的碰撞预警系统，通过利用先进的无线通信技术和新一代信息处理技术，实现车与车、车与路侧基础设施间的实时信息交互，告知彼此目前的状态(包括车辆的位置、速度、加速度、行驶路径)及获知的道路环境信息，协作感知道路危险状况，及时提供多种碰撞预警信息，防止道路交通安全事故的发生，成为当前各国试图解决道路交通安全问题的一种新的思路。
图1为相关技术中通过网络信息平台向车辆发送交通、调度信息的示意图，如图1所示，车联网(Vehicle to Everything，简称为V2X)：是指通过装载在车辆上的传感器、车载终端及电子标签提供车辆信息，采用各种通信技术实现车辆到车辆(Vehicle to Vehicle，简称为V2V)、车辆到行人(Vehicle to Pedestrian，简称为V2P)、车辆到路边单元(Vehicle to Infrastructure，简称为V2I)互连互通，并在信息网络平台上对信息进行提取、共享等有效利用，对车辆进行有效的管控和提供综合服务。
近年来随着新的移动通信技术的发展，国际上出现了使用长期演进LTE技术来解决基于车联网通信应用的研究，路边单元(Road Side Unit，简称为RSU)可以接收车辆请求，保证车辆接入Internet，有网关的功能；此外，它也拥有数据运算、存储、转发的功能。
图2是相关技术中车联网的架构示意图，如图2所示，车辆到路边单元(Vehicle to Road Side Unit，简称为V2R)，也可称为V2I，其中，车辆到路边单元RSU通信时的 主要特点包括:
(1)RSU广播时，广播信息只发送给它覆盖范围内的所有车辆；
(2)RSU和车辆之间是单跳传输，防止多跳带来的包传递成功率低、网络吞吐量低等不利影响；
(3)RSU可以快速的接收探测到经过的车辆、红绿灯和一些路况信息，并把这些信息进行处理、重新排序、蹄选之后再发给车辆。
上述三个方面保证车辆经过RSU时，通过与RSU建立连接保证车辆可以可靠、实时的接入Internet或者下载RSU存储的数据。
RSU具有短程覆盖(如数以百计米)、便宜、容易部署和高数据访问速度(大约l0mbps)的特点，对于V2R中RSU接入问题的研究还需要更深入的考虑以下几个因素：
1)车辆都处于高速移动状态，通常速度在60-70m/s之间，RSU的覆盖范围为1000米，车和RSU的通信链路在理想状态下维持13s～16s，因此某些文件不能在一个RSU覆盖范围内完成上传/下载；
2)RSU的部署没有统一管理、RSU带宽、信道资源有限，这就导致RSU的分布存在不均匀问题及车辆为了获得更多的带宽、信道资源而产生无序竞争行为。如城市场景下，多个RSU之间存在重叠区域时，车辆接入RSU策略不当时会导致RSU间负载不均衡，降低网络资源利用率。
针对相关技术车联网中的RSU难以满足当前车联网业务需求的问题，目前尚未提出有效的解决方案。
