Description

车联网中车队的管理方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种车联网中车队的管理方法及装置。
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。被动安全技术设置为在事故发生后，对车内、车外人员及物品的保护；主动安全技术设置为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***，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***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邻近服务(Proximity Services，简称为PS)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是相关技术中D2D技术的应用场景示意图，如图1所示，D2D的应用场景包括有三种，模式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；模式2：在弱/无覆盖区域的UE中继传输，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；模式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，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发现技术是指设置为判断/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，现有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，现有的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，也可以称为车车通信(vehicle to vehicle，简称为V2V)需要满足低时延和高可靠的指标要求。比如：两辆车之间距离太近，例如：车A和车B距离太近，需要注意车之间的行车安全。图2是相关技术中车辆交通的示意图，如图2所示，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。
图3是相关技术中车联网通信的示意图，如图3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(Vehicle to Infrastructure，简称为V2I)。V2I通信也称为V2R通信，R就是路边设备(Radio Side unit，简称为RSU)，V2I和V2R通信就是指Vehicle与网络间的通信，网络侧设备可以是：路边设备RSU，演进性节点eNB，中继relay等。
因此，在这些与车辆安全相关的应用场景下，采用V2V通信比较合适。进一步地，V2V通信可以采用3GPP所定义的上述D2D技术。为了实现V2V通信，每辆支持V2V 通信的车辆都需要获得通信所需的资源，例如：通信的频率和时隙等物理资源，当V2V通信采用3GPP所定义的D2D技术时候，V2V通信所需要的资源可以采用竞争的方式获得，如：先得到的先用，但这种方式可能在车辆多的区域下，产生资源拥塞和碰撞。如：有一块事先分配好的资源块，但多个车都使用相同的资源，例如：相同的频率资源和时隙资源，会导致这些车都无法使用该资源，从而使得这些车的信息都无法发送出去。所以，在V2V通信中，如果车辆采用竞争的方式获得资源池中资源，很容易产生碰撞而导致车辆信息不能及时发送出去。
基于以上原因，在一个区域中，如果车辆比较多，为了避免这些车辆竞争资源而导致拥塞，可以由网络为每个车都分配和调度资源，这样V2V通信时候，就不会出现多个车同时使用相同资源的情况了，每辆车的信息也可以及时地发送出去了。基于上述问题，相关技术中提出了一种车队管理/控制的方法，即：网络授权车队头获得车队的控制权，车队头为车队中的车辆提供资源管理、移动性管理和连接管理等。但是，由于车联网是一个动态移动和不断变化的网络，由于各种原因，比如车头中途暂停车，或者车头中途退出车队等等，使得车队失去车头，从而使车队正常管理出现混乱。
针对相关技术中车联网中车队的车头出现故障或离开车队时，导致车队管理出现混乱的问题，目前尚未提出有效的解决方案。

下面结合本发明的可选实施例对本发明进行举例说明；
本可选实施例提供了一种在车联网中的车队中设置辅助车头并通过该辅助车头管理车队的方法，该方法包括：在多个车辆组成一个车队中，为了防止一旦车队失去车头(对应于上述实施例中的主车头)，使车队处于混乱状态，在车头还在正常行使职责时，就设置一名辅助车头。一旦车头即将卸去车头职责时，告知车队自己将卸任车头，同时将车头职责移交给辅助车头，亦即此时辅助车头成为接任车头，实现无缝交接。
其中，对于本可选实施例中涉及到的车队辅助车头无缝接任车头的方法，包括：
当前车头即将主动离任，并向网络和/或者车队广播这一消息；或者由于其它原因，已经不具备充当车头的条件。当车头主动离任时，一般情况下，假设它车头职能正常。此时，可以由当前车头主动将车头职责移交给辅助车头；车头卸任前需要通知副头：车队成员标识、资源池；RSU或车头需要通知车队成员：副头的ID，位置，计算能力，存储空间等。
当车头不具备充当车头条件，或者已经无法广播通知车队时，车队会失去车头。此时，可以由网络侧设备指定辅助车头为接任车头；或者在覆盖外，没有网络时，副头可自动成为车头。并将消息广播给车队成员，辅助车头获得新的车头资格。
在覆盖内，当原车头离任，网络侧设备可以指定辅助车头，也可以指定任意车队成员为新车头；从车队成员的角度：获知原车头离任，新车头到来。网络可以通过一个流程广播给车队成员；也可以是：原车头先广播其失去，然后网络再广播新车头。
对于本可选实施例中涉及到的车队辅助车头的产生方法，包括：
步骤S21，根据第一指定预设条件，车队成员启动辅助车头“选择/重选辅助车头”的流程
其中，该第一指定预设条件，包括以下条件的一个或多个：(1)网络授权或车头通知车队将选择辅助车头；(2)辅助车头离开了网络覆盖或者网络信号质量差；(3)当前辅助车头不再具备车头的控制/管理能力；(4)有车队成员加入或退出车队。
上述条件(1)中，网络或者车头通过***广播消息(SIB)，或者通过专用信令通知车队成员；上述条件(1)中，网络或者车头通过V2I通信，通知车队成员。
上述条件(3)中，可以是车头通过V2V通信，通知车队成员将选择辅助车头。这个V2V通信，可以是D2D单播方式，或者D2D广播方式；也可以是网络或者车头通过V2I通信，通知车队成员，授权车队成员重新一个辅助车头。
步骤S22：根据第二指定预设条件，1个或多个车队成员成为备选辅助车头；
其中，车队成员根据该第二指定预设条件，就可以判断其自身是否符合条件并成为备选辅助车头。车队成员判断其能够成为备选辅助车头后，向车头上报其想成为备选辅助车头。需要说明的是，备选辅助车头条件与要求，可以与车队车头条件相当。
报告的内容中包括以下信息的一个或多个：备选辅助车头的标识符(也就是candidate vehicle head ID，也可称为candidate UE group head ID)，备选辅助车头的能力信息，备选辅助车头的信号质量，备选辅助车头的位置信息。
报告的方式可以采用3GPP所定义的D2D技术来实现，此时车与车之间的空中接口采用3GPP D2D技术中所定义的PC5接口，V2V通信可以采用D2D单播(即：PTP方式)方法也可以采用D2D多播方式(即：PTM方式)
该第二预设条件，包括以下条件的一个或多个：
条件1：网络或车头通知车队成员，成为备选辅助车头所需满足的要求
条件2：当车队成员无法读取SIB，则车队成员根据其自身存储的，成为备选辅助车头所需满足的要求
上述条件1中，网络可以通过***广播消息(SIB)，或者通过专用信令通知车队成员。
上述条件2中，车队成员自身存储的，成为备选车头的条件，可以是该车队成员原先在网络覆盖下读取到的网络配置的条件；车队成员自身存储的，成为备选车头的条件，可以是其注册到网络时候，读取到的网络配置的条件。
上述条件1和条件2中，网路或者车队成员自身存在的成为候选辅助车头所需满足的要求，包括以下条件的1个或多个：UE能力要求，UE信号质量要求，所处车队位置要求，出现多个备选辅助车头时候，由车头或者网络确定最终辅助车头。
车头或者网络根据每个备选辅助车头的报告，选择一个最合适的备选辅助车头成为辅助车头，并通知网络及所有车队成员。
图8是根据本发明可选实施例的车队中的车队成员自主启动辅助车头选择/重选流程图，如图8所示，该方法的步骤包括：
步骤S802：判断是否满足了预设条件，如果是，则执行步骤S804，否则流程结束；
步骤S804：判断是否满足了预设条件，如果是，则执行步骤S806，否则流程结束；
步骤S806：网络或者车头通过对所有备选辅助车头比较，确定哪个备选辅助车头可以成为新辅助车头；
步骤S808：网络或者车头向网络和或者车队成员通知新辅助车头信息。
本发明的实施例还提供了一种存储介质。可选地，在本实施例中，上述存储介质可以被设置为存储用于执行以下步骤的程序代码：
