Description

车联网信息传输方法、装置及系统 技术领域
本申请涉及但不限于通信领域,尤其涉及一种车联网信息传输方法、装置及系统。
背景技术
随着无线多媒体业务的发展,人们对高数据速率和用户体验的需求日益增长,从而对传统蜂窝网络的系统容量和覆盖提出了较高要求。另一方面公共安全、社交网络、近距离数据共享、本地广告等应用场景使得人们对了解附近人或事物并与之通信(Proximity Services,邻近服务)的需求逐渐增加。传统的以基站为中心的蜂窝网络在高数据速率以及邻近服务的支持方面存在明显的局限性,在这种需求背景下,代表未来通信技术发展新方向的设备到设备(Device-to-Device,简称为D2D)技术应运而生。D2D技术的应用,可以减轻蜂窝网络的负担、减少用户设备的电池功耗、提高数据速率,并改善网络基础设施的鲁棒性,很好地满足上述高数据速率业务和邻近服务的要求。
D2D技术可以工作在授权频段或非授权频段,允许多个支持D2D功能的用户设备,即D2D用户设备(D2D User Equipment,简称为D2D UE)在有网络基础设施或无网络基础设施的情况下进行直接发现/直接通信。图1是根据相关技术的D2D的应用模式的示意图,如图1所示,D2D的应用场景主要有以下三种:
1.UE1和UE2在蜂窝网络的覆盖下进行数据交互,用户面数据不经过网络基础设施,如图1的模式1;
2.在弱/无覆盖区域的UE中继传输,如图1中的模式2,允许信号质量较差的UE4通过附近有网络覆盖的UE3与网络进行通信,能帮助运营商扩展覆盖、提高容量;
3.在发生地震或紧急情况,蜂窝网络不能正常工作的情况下,允许设备间直接通信,如图1中的模式3,UE5、UE6和UE7间控制面和用户面都不 经过网络基础设施而进行一跳或多跳的数据通信。
D2D技术通常包括D2D发现技术和D2D通信技术,其中,D2D发现技术是指用于判断/确定第一用户设备是否邻近第二用户设备的技术。通常,D2D用户设备间可通过发送或接收发现信号/信息来发现对方。D2D通信技术是指D2D用户设备之间部分或全部通信数据可以不通过网络基础设施而直接进行通信的技术。
另一方面,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;主动安全技术即车联网技术是现代车辆安全技术发展的重点和趋势。
基于D2D技术的以上特点和优势,相关技术已经提出使用蜂窝无线通信以及D2D技术来实现车联网应用的可能,支持通信的主要场景包括即时通信和车辆预警两个方面。基于D2D/蜂窝通信的车联网系统,通过利用先进的无线蜂窝通信技术,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。
车联网通信的模式分为以下三类:车车通信(Vehicle-to-Vehicle Communications,简称为V2V)、车网通信(Vehicle-to-Infrastructure Communications,简称为V2I)、车人通信(Vehicle-to-Pedestrian Communications,简称为V2P),且这三类也可以统称为车联网通信(Vehicle-to-Everything Communications,简称为V2X)。其中V2I作为V2X服务的一种,其为使用V2I应用程序的UE与路侧单元(Road Side Unit,简称为RSU)之间的通信。其中RSU为支持V2I服务的实体,可从使用V2I 应用程序的UE接收数据或发送数据至使用V2I应用程序的UE。
RSU可由基站或静止的UE实现。RSU的功能主要包括:1)周期性发送V2I广播消息给附近的车载用户设备(Vehicle UE);2)接收来自Vehicle UE的V2I消息,然后广播相应的V2I消息;3)与Vehicle UE进行一对一通信;4)与交通安全服务器相连并通信。但相关技术尚未能解决需大范围内广播V2I消息场景下的信息传输问题。
针对相关技术中,大范围内车联网信息的传输问题,目前还没有有效的解决方案。
