Abstract

Description

资源的配置方法、装置及存储介质 技术领域
本发明涉及通信领域，具体而言，涉及一种资源的配置方法、装置及存储介质。
背景技术
车联网通信(Vehicle-to-Everything Communications，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通信(Vehicle-to-Vehicle Communication，简称为V2V)、车与人通信(Vehicle-to-Pedestrian Communications，简称为V2P)、车与网络基础设施通信(Vehicle-to-Infrastructure Communications，简称为V2I)，车与网络(Vehicle-to-Network Communications，简称为V2N)通信，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。
目前，第三代合作伙伴(3rd Generation Partnership Project，简称为3GPP)正在讨论基于(Long Term Evolution，简称为LTE)的V2X。基于参与到通信的另一方，V2X业务可以分为V2V业务、V2I业务、V2N业务和V2P业务。V2P业务是指UE之间使用V2P应用通信的业务。V2N业务是指UE和服务实体使用V2N应用通过LTE网络实体进行相互通信的业务。V2I业务是指用户设备(User Equipment，简称为UE)和路边单元(Road Side Unit，简称为RSU)使用V2I应用进行交互的业务。RSU是支持V2I业务的实体，可以发送V2I业务到使用V2I应用的UE，也可以从使用V2I业务的UE接收V2I业务。RSU可以通过演进性基站(Evolved Node B，简称为eNB)或者静止的UE实现。如果RSU是通过基站实现的，即称为eNB type RSU。如果RSU是通过UE实现的，即称为UE type RSU。V2V业务是指UE之间使用V2V应用通信的业务。V2V包括UE之间直接交互V2V相关应用信息，或者由于V2V直接通信范围的限制，UE之间通过支持V2X业务的基础设施(例如RSU，应用服务器等)进行V2V相关应用信息交互。
在V2V/V2P/V2I车联网通信模式下，车联网信息的传输大多以广播和组播方式为主。现有系统基站支持基于MBSFN以及SC-PTM的广播机制，此外UE到UE的直接发现/通信(D2D，sidelink，ProSe)机制也可以支持通过PC5接口进行车联网消息的广播传输。由于车联网通信的低延时特性，对于进行V2X消息传输的UE，在发生切换或异常情况时，保证服务连续性或减少业务中断时间至关重要，然而，针对该问题，目前尚未存在有效的解决方案。

步骤S602：源基站eNB1根据设备单元上报的测量报告及无线资源管理信息，决定进行基于X2接口的切换。
步骤S604：源基站选择目标基站，并向目标基站发送切换请求消息。
其中，切换请求中可携带V2X传输兴趣指示信息。
步骤S606：目标基站向源基站发送切换请求确认消息，其中触发设备单元进行切换的切换命令中携带PC5通信资源。
其中，PC5通信资源包括以下任意之一或组合：车联网通信发送资源/资源池、车联网通信接收资源池、车联网通信异常发送资源池、车联网通信异常接收资源池。此外，在可选本实例中，该PC5通信资源可以包括：车联网通信发送/接收资源(调度资源)，车联网通信异常发送/接收资源池。
步骤S608：基站通过RRC连接重配消息将切换命令(携带PC5通信资源)透传给用户设备。
步骤S610：UE1与目标小区完成下行同步后，UE1使用目标小区V2X通信资源将Uu口V2X传输切换到PC5接口传输；
步骤S612：判断UE1是否发生切换；

可选实例4
图9是根据本发明可选实施例的为基站通过专有信令发送V2X通信异常发送/接收资源池的方法流程图，该方法为UE1在通过Uu口进行V2X传输，如图9所示，该方法的步骤包括：
步骤S902：UE1发送PC5车联网传输兴趣指示或PC5路径切换指示信息给基站；
其中，PC5车联网传输兴趣指示或PC5路径切换指示用以向基站指示，UE1在通过Uu口传输V2X消息，并且有兴趣切换到PC5接口进行V2X传输.其中，UE1通过旁链用户信息sidelinkUEInformation向基站发送PC5路径切换指示或PC5车联网传输兴趣指示信息。
