Description

一种按需加入车联网的方法及终端 技术领域
本发明涉及无线通信技术领域，尤其涉及一种按需加入车联网的方法及终端。
背景技术
本申请发明人在实现本申请实施例技术方案的过程中，至少发现相关技术中存在如下技术问题：
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。
美国国家公路交通安全管理局的调查报告显示，80％的公路交通事故是由于驾驶员在事故发生前3秒内的疏忽造成的。戴姆勒-奔驰公司的一项实验表明，如果提前0.5秒示警驾驶员，可以避免60％的追尾事故；若驾驶员能提早1.5秒得到示警并采取措施，则可以避免90％的追尾撞车事故。基于通信的碰撞预警系统，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。
同时，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的邻近服务(Proximity Services)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(D2D，Device-to-Device)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，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。D2D的应用场景主要有三种：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。
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。车辆预警可能会包括碰撞预警、变道预警 等，但这种场景下对时延的要求非常高，相关的D2D技术无法实现。
车联网通信中，许多场景下车辆与车辆之间的通信，简称：车车通信(V2V，vehicle to vehicle)需要满足低时延和高可靠的指标要求。比如：两辆车之间距离(如：车A和车B)太近，需要注意车之间的行车安全。如果：车A先将其自身的位置/车速等信息报告给网络，再由网络通知车B，则车B获得车A的位置/车速等信息有延时，会导致车B无法迅速避让车A(如图2所示)。
在车联网通信中，将这种车与网络间的通信称为车对路侧基础设施(V2I，Vehicle to Infrastructure)。本文中，V2I通信也称为V2R通信，R就是路边设备(RSU，Radio Side unit)，V2I和V2R通信就是指Vehicle与网络间的通信，网络可以是：RSU，基础建设(Infrastructure)，节点B(eNB)，中继(relay)等，如图3所示。
目前的车联网架构下主要考虑车联网中的车载终端和RSU，以及网络之间的交互，对于车载终端来说，是开启车载终端时就需要启动车联网应用以接入后台的云服务器进行信息交互，然而，网络中还存在大量的普通类型的终端，通过车联网应用也可以接入后台的云服务器进行信息交互，可是，对于普通类型的终端并不需要开机就启动车联网应用。
针对这类终端，采用相关技术存在的问题为：如果要求对于普通类型的终端也按照车载终端一样的运行模式，持续地与后台的云服务器及用户终端间进行交互，会对普通类型的终端的功耗造成巨大的消耗。
