Description

业务转发方法及装置 技术领域
本申请涉及但不限于通信领域，尤其涉及一种业务转发方法及装置。
背景技术
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、车与路侧基础设施之间的实时信息交互，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，成为当前多个国家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)、车与路或基础设施(Vehicle to Infrastructure，简称为V2I)的互连互通，并且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以及提供综合服务。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。
路边通信单元(Road Side Unit，简称为RSU)可以接收车辆请求，保证车辆接入因特网(Internet)，有网关的功能；此外，它也拥有数据运算、存储、转发的功能。
目前车联网实现技术包括：专用短距离通信(Dedicated Short Range Communication，简称为DSRC)和长期演进(Long Time Evolution，简称为LTE)，其中DSRC基于电气与电子工程师协会(Institute of Electrical and Electronics Engineers，简称为IEEE)802.11P和IEEE 1609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。
目前第三代合作伙伴计划(3rd Generation Partnership Project，简称为3GPP)正在讨论的LTE V2X技术包括：RSU可以通过静止的用户设备(User Equipment，简称为UE)或基站(eNB)实现，V2V/V2I/V2P可能通过PC5接口或Uu口实现，其中PC5接口是指设备到设备(Device to Device，简称为D2D)的空中接口，Uu口是指UE与eNB之间的空中接口。
为了有效地利用移动网络资源，3GPP提出了多媒体广播多播业务(Multimedia Broadcast Multicast Service，简称为MBMS)，该业务是一种从一个数据源向多个目标移动终端传送数据的技术，实现了网络(包括核心网和接入网)资源的共享，提高了网络资源(尤其是空中接口资源)的利用率。3GPP在版本13(Release 13，简称为R13)的高级长期演进(Long Time Evolution，简称为LTE-A)中提出了单小区MBMS的研究课题，其中，单小区MBMS业务在物理下行共享信道(Physical Downlink Shared Channel，简称为PDSCH)上传输。
然而，针对相关技术中难以通过Uu口转发V2X业务的问题，目前尚未存在有效的解决方案。

下面结合不同场景对本可选实施例进行详细说明；
场景1：
图7是根据本发明实施例的源OBU和目标OBU位于一个基站eNB覆盖内示意图，结合图7进行说明；
1、OBU接收V2X转发准则(对应于上述实施例中的转发策略)。
1.1)转发准则可以是eNB通过Uu口向OBU周期性发送，或者OBU通过非接入层NAS信令或应用层信令接收转发准则；
转发准则可用于向OBU指示哪些V2X业务可通过Uu口转发，eNB可根据以下至少之一确定转发准则：运营商策略、Uu口负载、本地负载。准则可通过RRC信令传输。准则信息至少可包括：V2X业务类型，V2X业务类型是指以下至少之一：周期性V2X业务、事件触发V2X业务、基本安全消息。准则信息还可包括：V2X业务大小、时段、概率、发送频率或周期、OBU标识、优先级等，其中V2X业务大小是指符合准则中指示大小的V2X业务可以通过Uu口转发；时段是指该时段内可通过eNB转发；概率是指：需要转发V2X业务的OBU随机选取一个(0，1)之间的数值，如果该数值不大于准则中的概率值，则该OBU可以采用Uu口转发V2X业务；发送频率或周期是指V2X业务在Uu口的发送频率或周期；OBU标识是指可以采用Uu口转发V2X业务的OBU；优先级是指不低于该优先级的V2X业务可以通过eNB转发，优先级可通过QoS等级标识(QCI，QoS Class Identifier)指示。
可选地，eNB设置用于Uu口转发的资源池，资源池可在准则信息中指示或单独指示，资源池可用于OBU向eNB上传V2X业务，可包括时频位置、功率配置等。本可选实施例中的V2X业务可包括以下至少之一：V2V、V2I、V2P、V2N。
1.2)如果eNB没有指示转发准则(如通过NAS信令或应用层信令指示转发准则)或者OBU不符合转发准则或者转发准则中不包括资源配置信息(如资源池)，则OBU可以向eNB发送转发请求，转发请求可通过无线资源控制(Radio Resource Control，简称为RRC)信令传输，转发请求可包括：OBU标识、和/或V2X业务标识；还可包括：原因、时段、V2X数据大小、V2X数据发送频率或周期、V2X业务优先级、V2X业务时延。其中：原因用于指示OBU请求转发的理由，时段、数据大小以及发送频率与前述相同， V2X业务优先级是指优先级标识，如QoS等级标识(QCI，QoS Class Identifier)，V2X业务时延是指V2X业务的时延要求。
eNB可接收到OBU的转发请求消息，eNB可判断是否接受请求，如果是，则向OBU发送成功指示响应，否则，向OBU发送失败指示响应。eNB可根据以下至少之一确定是否接受请求：运营商策略、Uu口负载、本地负载。如果运营商策略允许转发且/或Uu口和eNB本地负载允许转发，则eNB可发送成功响应消息。eNB发送的响应消息可通过RRC信令传输。
可选地，eNB根据OBU请求消息为V2X业务分配Uu口上传资源，并将上传资源的资源配置信息发送给OBU，资源配置信息可通过L1/L2层或RRC层信令发送。
2、OBU通过Uu口上传V2X业务数据。
OBU可根据eNB的转发准则或者eNB的响应消息通过Uu口上传V2X业务，V2X业务可以是指允许通过Uu口转发的V2X业务。
OBU可根据eNB指示的资源或在资源池中选择的资源上传V2X业务。上传可采用不大于eNB指示的发送频率在Uu口周期性进行。
可选地，如果V2X业务对应的事件结束，或者eNB指示停止Uu口上传，或者Uu口上传时段结束或超时，则OBU停止上传V2X业务；可选地，在停止上传之前，OBU可向eNB发送指示信息：停止Uu口转发。
3、eNB确定转发V2X业务的方式。
eNB可在OBU上传资源上接收OBU发送的V2X业务数据，如果不知道OBU选择的发送资源，eNB可在资源池中盲检V2X业务数据。eNB可首先确定接收到的数据为需要进行转发的V2X业务，eNB可通过以下至少之一进行确定：V2X业务标识、资源位置、转发标识；
eNB可根据V2X业务属性和本地策略选择转发方式，转发方式可包括以下至少之一：单小区点到多点SC-PTM、系统广播消息SIB、寻呼消息、MBSFN、PWS、单播。
4、eNB转发V2X业务数据。
eNB可根据业务属性和运营商策略确定V2X业务的转发区域，转发区 域可包括：源OBU所在小区，或者，源OBU所在小区和邻小区。
5、目标OBU检测并接收所需的V2X业务。
源OBU可以是指通过Uu口上传V2X业务的OBU，目标OBU可以是指通过Uu口接收V2X业务的OBU。
场景2：
图8是根据本发明实施例的源OBU和目标OBU分别位于不同的eNB的示意图，结合图8进行说明；
2.1)eNB之间有X2接口
除了场景1中的步骤，还可包括以下步骤：a)源OBU所在的eNB确定收发双方OBU位于不同的eNB覆盖内。b)源eNB通过X2口和目标OBU所在的eNB进行交互，交互内容可包括：源eNB请求目标eNB通过Uu口转发V2X业务，目标eNB响应源eNB的请求；eNB之间通过X2口传输V2X业务数据和资源配置信息；c)最后形成如下V2X业务数据传输路径：源OBU->源eNB->目标eNB->目标OBU。
2.2)eNB之间无可用X2接口
与2.1)中场景类似：源OBU和目标OBU分别位于不同的eNB覆盖中，区别是：eNB之间没有可用的X2接口。此时eNB之间通过S-GW转发V2X业务数据，同时控制面信令通过移动性管理实体(Mobility Management Entity，简称为MME)实现。最终的V2X业务数据传输路径如下：源OBU->源eNB->S-GW->目标eNB->目标OBU。
为了保证V2X业务的可靠性，OBU在向eNB发送V2X业务数据的同时，可以继续在PC5上广播发送V2X业务数据。目标OBU可从Uu或PC5上接收所需的V2X业务。
车载单元OBU可以相当于用户设备UE或车载移动终端；
基站转发准则或响应消息可通过系统广播消息或专用RRC消息发送；系统广播消息可以是相关技术(如3GPP规范)中的SIB消息增加相应字段或者专门为V2X新增的SIB消息；
场景3：
图9是根据本发明实施例的源OBU位于eNB覆盖外示意图，结合图9进行说明，该场景与场景1的步骤类似，区别包括：OBU2发现或选择UE-to-网络(Network，简称为NW)中继(relay)，源OBU2通过relay向eNB发送信令和V2X数据，eNB通过relay向OBU发送转发准则、信令和响应消息。最终形成的V2X业务数据路径为：源OBU2->relay->eNB->目标OBU(如OBU1)。
下面基于上述不同的场景和相应的示例对本可选实施例进行详细的说明；
