一种消息传输的省电方法及相关设备
本申请要求于2016年10月09日提交中国专利局，申请号为201610882051.0、发明名称为“一种消息传输的省电方法及相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线网络技术领域，尤其涉及一种消息传输的省电方法及相关设备。
背景技术
为了提升交通系统的安全性和智能化，智能交通的系统理念逐渐兴起。智能交通可以利用新一代的通信网络和数据处理能力，提高交通系统的整体效率，降低能量损耗，增加运输的安全和便捷。如图1所示，图1提供了一种V2X（Vehicle to Everything，车联网）系统的架构示意图，该V2X系统包括V2V（Vehicle to Vehicle，车车通信）、V2P（Vehicle to Pedestrian，车人通信）、V2I（Vehicle to Infrastructure，车路通信）及V2N（Vehicle to Network，车网通信）等多种方式，V2X技术允许汽车与所有附近其它汽车及道路基础设施进行连续通信，比如，汽车与红绿灯、校区和铁路道口等设施之间通信。通信设备可以是车内嵌入式远程信息处理系统，或者是智能手机等移动设备。V2X技术使得车与车、车与基站、基站与基站之间能够通信，从而获得实时路况、道路信息、行人信息等一系列交通信息，从而提高驾驶安全性、减少拥堵、提高交通效率、提供车载娱乐信息等，基于D2D （Device-to-Device，设备对设备）技术可以实现V2X通信。
图2是现有技术方案提供的一种基于PC5空口的D2D SL（Sidelink，副链路）的V2P传输方式，图3是现有技术方案提供的一种基于Uu空口的LTE UL（Uplink，上行链路）+DL(Downlink，下行链路)的V2P传输方式。在不改变现有3GPP（3rd Generation Partnership Project，第三代合作伙伴计划）协议框架和设计的前提下，可以通过复用现有通信机制（包括R13 D2D随机资源选择和R14 PC5 based V2V sensing空闲资源选择）支持V2P通信。如图2所示，V2P通信的一方是车载终端（Vehicle UE，V-UE），一方是行人所持的用户终端（Pedestrian UE，P-UE），且V2P通信可以是双向的，即V-UE发送、P-UE接收，或者P-UE发送、V-UE接收。但是，由于P-UE的电池电量是有限的，可能出现P-UE电量迅速消耗殆尽无法满足发送或者接收与车联网紧急预警有关的V2P消息的情况，因此，如何减少车联网V2P消息传输的电量消耗，是一个亟待解决的问题。

如图4所示，当P-UE处于特定地理位置（例如，十字路口、人行横道等），P-UE接收V-UE对外广播的位置、速度、轨迹等信息；如图5所示，P-UE可以对外广播发送自己的位置、速度、加速度、轨迹等状态，P-UE也可以基于用户选择（根据室内或室外状态、与V-UE的距离或用户活动状态来判断是否处于危险情况）接收处理V-UE发送的广播消息；P-UE周期性地对外广播发送自己的位置、速度、朝向等感知信息，当V-UE检测到可能的碰撞危险时，P-UE接收来自V-UE发送的碰撞危险告警消息。基于上述三种V2P消息传输的场景，本发明实施例提供了一种V2P消息传输的省电方法。
请参考图6，图6是本发明提供的一种消息传输的省电方法的流程示意图。如图所示，本发明实施例的方法包括：
S601，当用户终端处于无线资源控制连接状态时，用户终端向基站发送所述用户终端当前的运行状态信息。
具体实现中，在基站调度模式或者资源池自选模式下，用户终端均可以通过无线资源控制信令按照预设周期向基站发送用户终端当前的运行状态信息，其中，所述运行状态信息包括地理位置信息（如：室内或室外、十字路口、人行横道等）、运动状态信息（速度、轨迹等）、用户活动信息（阅读、上网、听音乐等）以及当前剩余电量中的至少一种，所述基站调度模式为基站向用户终端分配时频资源的方式，所述资源池自选模式为基站将时频资源划分为多个资源池并由用户终端自选资源池的方式。特别的，地理位置信息可以复用现有的RRC IE locationInfo进行上报。

例如，当地理位置信息为十字路口且运行速度超过预设速度时，由于用户有可能与车辆发生碰撞危险，因此基站可以激活所述用户终端的消息发送或接收能力，从而用户终端可以接收或者发送碰撞危险警告消息；或者，当用户活动信息为用户正在上网、听音乐时，由于用户终端当前的电量消耗大，因此基站可以失效所述用户终端的消息发送或接收能力，从而达到省电作用；或者，用户终端的当前剩余电量低于预设阈值，因此基站可以失效所述用户终端的消息发送或接收能力，从而达到省电作用。
S603，基站向所述用户终端返回携带有传输指示信息的无线资源控制信令。其中，所述传输指示信息包括激活所述用户终端的消息传输能力或失效所述用户终端的消息传输能力。
S604，用户终端根据所述传输指示信息，控制所述用户终端与车载终端进行消息传输。

在资源池自选模式下，当所述传输指示信息为激活所述用户终端的消息发送能力时，所述用户终端向所述车载终端开始发送广播消息；当所述传输指示信息为失效所述用户终端的消息发送能力时，所述用户终端向所述车载终端停止发送广播消息；当所述传输指示信息为激活所述用户终端的消息接收能力时，所述用户终端开始监听接收资源池，并接收所述车载终端发送的V2P广播消息，为了进一步省电，用户终端可以仅监听与Zone ID（资源池分区标识）相关联的接收资源池；当所述传输指示信息为失效所述用户终端的消息接收能力时，所述用户终端停止监听接收资源池，并停止接收所述车载终端发送的V2P广播消息。
在本发明实施例中，首先当用户终端处于无线资源控制连接状态时，用户终端向基站发送所述用户终端当前的运行状态信息，基站接收到运行状态信息之后，根据所述运行状态信息判断是否激活或失效所述用户终端的消息传输能力并向所述用户终端返回携带有传输指示信息的无线资源控制信令；用户终端接收所述基站发送的携带有所述传输指示信息的无线资源控制信令；用户终端根据所述传输指示信息，控制所述用户终端与车载终端进行消息传输。通过控制和使能P-UE发送或者接收V2P消息的能力，实现了P-UE的省电目的。

S702，当所述用户终端处于无线资源控制空闲状态或网络覆盖之外时，所述用户终端根据所述预配置参数，控制所述用户终端与车载终端进行消息传输。
具体实现中，所述预配置参数包含传输指示信息，当所述传输指示信息为激活所述用户终端的消息发送能力时，所述用户终端向所述车载终端开始发送广播消息；或当所述传输指示信息为失效所述用户终端的消息发送能力时，所述用户终端向所述车载终端停止发送广播消息；当所述传输指示信息为激活所述用户终端的消息接收能力时，所述用户终端开始监听预配置的接收资源池；当所述传输指示信息为失效所述用户终端的消息接收能力时，所述用户终端停止监听预配置的接收资源池。
可选的，在所述预配置参数未包含传输指示信息时，由所述用户终端高层控制所述用户终端与车载终端进行消息传输。其中，用户终端高层可以为用户终端的应用层。进一步的，用户终端可以根据当前的运行状态信息，判断是否激活或失效所述用户终端的消息传输能力，进而控制所述用户终端与车载终端进行消息传输，判断方法与上述实施例相同，本实施例不再赘述。
