Description

车联网V2X业务传输路径的选择方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种车联网V2X业务传输路径的选择方法及装置。
背景技术
随着经济社会高速发展，汽车使用量迅速增长，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。
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与车(Vehicle to Vehicle，简称为V2V)、车与人(Vehicle to Pedestrian，简称为V2P)、车与路(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。图1为通过网络信息平台向车辆发送交通、调度信息的示意图。
近年来随着新的移动通信技术的发展，国际上出现了使用LTE技术来解决基于车联网通信应用的研究。
路边通信单元(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。
目前有两种车联网实现技术：专用短距离通信(Dedicated Short Range Communication，简称为DSRC)和LTE，其中DSRC基于IEEE802.11P和IEEE1609系列标准，802.11P负责物理层和媒体接入控制(Medium Access Control，简称为MAC)技术，1609负责上层规范。基于LTE的V2X技术刚开始讨论，还没有标准。
目前3GPP正在讨论的LTE V2X技术包括：RSU可通过静止的UE或eNB实现，V2V/V2I/V2P可能通过PC5接口或Uu接口实现，其中PC5接口是指设备到设备D2D的空中 接口，Uu接口是指UE到eNB的空中接口。
在对相关技术中的车联网的研究和实践过程中，发明人发现存在以下问题：V2X业务可通过PC5或Uu接口传输，由于车辆的移动，导致PC5/Uu接口的信道质量变化，原有的传输路径不再适合V2X业务，进而使得V2X业务传输受阻。
针对相关技术中的上述问题，目前尚未存在有效的解决方案。

需要说明的是图2所示的实施例是从RSU侧来进行说明的，下面将结合本实施例的可选实施方式对以RSU为主语的技术特征进行相应的说明；
对于本实施例中涉及到的传输路径可以是：用于传输V2X业务的接口、用于传输V2X业务的中继relay、用于传输V2X业务的邻小区，其中，用于传输V2X业务的接口包括：Uu接口、PC5接口。
在本实施例的可选实施方式中，基于上述传输路径，在RSU与OBU之间正在使用的传输路径为Uu接口时，本实施例中涉及到的传输的第一优先级顺序由高到低的顺序为：Uu接口、邻小区、PC5接口、中继relay；而在RSU与OBU之间当前传输路径为PC5接口时，传输的第二优先级顺序由高到低的顺序为：PC5接口、Uu接口、中继relay。

需要说明的是，上述各个模块是可以通过软件或硬件来实现的，对于后者，可以通过以下方式实现，但不限于此：上述模块均位于同一处理器中；或者，上述模块分别位于多个处理器中。
下面结合本发明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转换V2X业务发送模式的方法，该方法包括：基站eNB发送车联网V2X相关测量参数，车载单元OBU测量V2X业务传输路径PC5接口或Uu接口的信号质量，在基站覆盖内，OBU向eNB上报测量结果，eNB确定OBU的V2X业务传输路径；或者，在基站覆盖外，OBU根据测量结果选择V2X业务传输路径。
下面结合本发明的具体应用场景，对本发明可选实施例进行说明；
应用场景1：基站覆盖内，V2X传输模式转换；
1.1)Uu->PC5
图6是根据本发明可选实施例的基站覆盖内V2X传输模式转换的示意图，如图6所示，OBU1和OBU2通过Uu口进行V2X通信，V2X包括：V2V，V2I，V2P.该场景下有两种可能的用例：
1.1.1)基于测量的转换：Uu->PC5，Uu->relay
eNB设置Uu口V2X通信的测量配置，测量配置至少包括：测量对象，即测量哪个eNB对应的Uu口，进一步还包括：测量门限，测量周期，测量事件等。测量门限是指OBU测量满足门限时上报eNB，测量周期用于周期性测量，测量事件用于事件触发测量。OBU1和OBU2分别测量Uu口的信号质量，如参考信号接收功率(Reference Signal Received Power，简称为RSRP)，参考信号接收质量(Reference Signal Received Quality，简称为RSRQ)，参考信号的强度指示(Reference Signal Strength Indicator，简称为RSSI)等数据，当满足测量配置时，如信号质量下降到测量门限，OBU上报测量结果到eNB，eNB确定Uu口不适合继续传输V2X业务和/或不能通过小区切换实现V2X业务，则eNB向OBU(收发双方)指示开放PC5接口(可能有直通或relay)，如果PC5接口质量可以满足V2X业务需求，则OBU之间通过PC5发送V2X业务。如果PC5质量不能满足V2X业务需求，则OBU发现/选择relay继续进行V2X业务，relay为D2D中的Relay，如果OBU选择了relay，需要向eNB发送请求/指示信息，收到eNB发送的确认信息后，OBU通过relay继续进行V2X业务。
1.1.2)eNB发起的转换：
eNB是指进行V2X通信的eNB，eNB确定正在进行的Uu口V2X业务需要转换到PC5接口，可能的原因是：负载均衡，即eNB判断自身的Uu口负载过重且不能通过切换到邻小 区缓解，为了不影响普通LTE业务，需要将一部分V2X业务转移到PC5接口。eNB向收发双方的OBU发送指示信息：将V2X业务转换到PC5。OBU通过PC5接口继续V2X业务。如果PC5接口不能满足V2X业务的需求，OBU向eNB发送指示信息，并根据eNB的响应信息继续下一步的行为，如eNB可以选择切换V2X业务到邻小区或选择relay进行V2X通信等。
上述eNB通过RRC信令向OBU发送转换到PC5的指示信息。
1.2)Uu->relay
Uu->relay.即eNB判断不能通过Uu或PC5直接进行V2X通信，但eNB确定可以采用relay进行V2X通信，则eNB通过RRC信令向OBU发送指示信息，OBU根据指示发现/选择relay进行V2X通信。
1.3)PC5->Uu
注意：本场景测量的对象是PC5接口，eNB进行PC5接口的测量配置并通知OBU，OBU根据测量配置对PC5接口进行测量和上报。对PC5接口的测量信号可以包括以下至少之一：RSRP，RSRQ，RSSI.
接收方OBU检测到PC5质量下降到门限，上报测量结果到eNB，eNB确定采用Uu继续V2X通信，eNB指示OBU双方建立RRC连接，通过eNB继续V2X业务。
如果原通过PC5通信的OBU处于RRC-Idle状态，则OBU首先建立RRC连接，进入RRC-Connected状态，然后发送测量报告或进行V2X业务。
1.4)PC5->relay
OBU测量PC5接口的信号质量并上报eNB，eNB确定不能通过Uu或PC5直接进行V2X通信，但eNB确定可以采用relay进行V2X通信，则eNB通过RRC信令向OBU发送指示信息，OBU根据指示发现/选择relay进行V2X通信。
1.5)relay->relay
OBU通过relay进行V2X通信，OBU测量到relay的PC5接口信号质量并上报eNB，eNB确定只能通过选择新的relay进行V2X通信，则eNB通过RRC信令向OBU发送指示信息，OBU根据指示发现/选择新的relay进行V2X通信。
1.6)relay->PC5
OBU间通过relay进行V2X通信，OBU测量到relay的PC5接口信号质量并上报eNB，eNB确定可通过直接的PC5接口进行V2X通信，则eNB通过RRC信令向OBU发送指示信息，OBU根据指示通过PC5接口直接进行V2X通信。
1.7)relay->Uu
OBU间通过relay进行V2X通信，OBU测量到relay的PC5接口信号质量并上报eNB， eNB确定可通过Uu接口进行V2X通信，则eNB通过RRC信令向OBU发送指示信息，OBU根据指示通过Uu接口进行V2X通信。
应用场景2：OBU移动到LTE基站覆盖外，V2X传输模式转换；
2.1)PC5->relay
图7是根据本发明可选实施例的OBU移动到LTE基站覆盖外，V2X传输模式转换示意图，如图7所示，OBU在LTE覆盖内采用PC5进行V2X通信，OBU离开LTE覆盖，检测到PC5质量下降到门限，需要发现/选择relay以继续V2X业务，如果没有relay，则业务中断；在eNB内小区边缘，如果PC5质量低于门限，OBU上报测量结果到eNB，eNB发现不能使用Uu(Uu质量也低于门限)，eNB指示OBU发现/选择relay继续V2X业务。
2.3)Uu->PC5
OBU在LTE覆盖内采用Uu进行V2X通信，OBU移动到LTE覆盖外采用PC5进行V2X通信。
2.4)Uu->relay
OBU在LTE覆盖外选择relay进行V2X通信。
2.5)relay->PC5
OBU在LTE覆盖内采用relay进行V2X通信，OBU离开LTE覆盖，检测到relay的PC5接口质量下降，而OBU之间的PC5信号质量上升，OBU通过直接的PC5接口进行V2X通信。
