Description

V2X消息发送方法、装置及系统 技术领域
本发明实施例涉及车联网领域,特别涉及一种V2X消息发送方法、装置及系统。
背景技术
在智能交通系统(Intelligent Transportation System,ITS)中,通过车辆与车辆之间(Vehicle to Vehicle,V2V)通信,或者车辆与路边基础设施(Vehicle to Infrastructure,V2I)通信,或者车辆与行人之间的(Vehicle to Pedestrian,V2P)通信,或者车辆与网络(Vehicle to Network,V2N)通信来及时获取有关交通的各种信息,这些通信方式可以统称为车辆与外界(Vehicle to X,V2X)通信。X是车辆、路边基础设施、行人和网络的统称。
在通过长期演进(Long Term Evolution,LTE)技术传输V2X消息时,两个用户设备(User Equipment,UE)之间可以直连通信。在两个UE直连通信时,eNB先向UE配置传输资源池;UE采用先侦听信道后选择传输资源的方式,从传输资源池中选择出处于空闲状态的传输资源;然后使用该处于空闲状态的传输资源发送V2X消息。先侦听信道后选择传输资源的方式是指:UE对传输资源池中的各个传输资源进行侦听,侦听时长的典型值为1000ms,然后根据侦听结果确定出处于空闲状态的传输资源。
由于上述方式需要花费至少1000ms的侦听时长,才能选择出处于空闲状态的传输资源,所以并非适用于所有的V2X消息发送场景。在一些特定发送场景下,比如UE初次获取到传输资源池的配置信息后,即便存在待传输的V2X消息,也需要等待1000ms的侦听时长后,才能选择出处于空闲状态的传输资源对该V2X消息进行发送,由于V2X消息的传输时延需求为100ms或20ms,等待1000ms的侦听时长会导致V2X消息发送失败。

在两个终端120实现V2X通信时,第一种通信方式是:一个终端120发送的V2X消息,通过接入网设备140的中转,发送至另一个终端120;第二种通信方式是:两个终端120之间直连通信。本发明实施例中,主要涉及两个终端120之间直连通信的情况。
当两个终端120之间直连通信时,需要接入网设备140预先向终端120配 置传输资源池,由终端120从传输资源池中选择出处于空闲状态的传输资源,使用该处于空闲状态的传输资源发送V2X消息。
其中,V2X消息包括:V2V消息、V2I消息、V2P消息和V2N消息中的至少一种。可选地,V2X消息是指携带有V2X数据的消息,或者,V2X消息即为V2X数据。
图2示出了本发明一个实施例提供的消息发送方法的方法流程图。本实施例以该消息发送方法应用于图1所示的终端120中来举例说明。该方法包括:
步骤201,获取第一配置信息,第一配置信息用于确定第一传输资源池;
可选地,第一配置信息由接入网设备向终端配置。也即,终端接收接入网设备发送的RRC专用信今,从RRC专用信今中获取第一配置信息;或者,终端接收接入网设备发送的系统信息,从系统信息中获取第一配置信息。系统信息是接入网设备发送的广播信息。
可选地,第一配置信息是预配置的第一配置信息。也即,该第一配置信息是根据LTE相关的通信协议预先约定,并预先存储在终端中的配置信息。对于第一配置信息是预配置的第一配置信息时,终端读取内部存储的第一配置信息即可。
步骤202,根据第一配置信息确定第一传输资源池;
步骤203,在确定满足预定条件时,使用第一传输资源获取方式在第一传输资源池中选择第一传输资源;
可选的,预定条件是根据特定发送场景所设置的条件。其中,特定发送场景是指:使用具有侦听时长T2(典型值为1000ms)的先侦听信道后选择传输资源的方式来选择传输资源,会导致V2X消息的发送失败或不能满足传输时延需求的场景
可选的,第一传输资源获取方式在选择传输资源时所花费的时间小于V2X消息的传输时延需求值。可选的,传输时延需求值是100ms或20ms。
可选的,第一传输资源获取方式包括如下三种方式中的任意一种:
1、随机选择方式;
2、具有侦听时长T1的先侦听信道后选择传输资源的方式,侦听时长T1小于V2X消息的传输时延需求值;
3、带有碰撞规避的载波侦听多路访问技术(Carrier Sense Multiple Access  with Collision Avoidance,CSMA/CA)方式。
步骤204,使用第一传输资源发送V2X消息。
综上所述,由于第一传输资源获取方式在选择传输资源时的速度较快,通过在确定满足预定条件时,使用第一传输资源获取方式在第一传输资源池中选择第一传输资源,使用第一传输资源发送V2X消息,保证了V2X消息能够在满足预定条件时的特定发送场景下也能够正常传输。
上述特定发送场景至少包括两类场景。下文中采用图3和图4对本发明实施例在第一类场景中的实施方式进行阐述;采用图5和图6对本发明实施例对在第二类场景中的实施方式进行阐述。
参考图3,接入网设备140向终端120配置第一传输资源池32和第二传输资源池34。在第一类特定发送场景下,终端120使用第一传输资源池32中的传输资源发送V2X消息,第一传输资源池32使用选择速度较快的第一传输资源获取方式;在普通发送场景下,终端120使用第二传输资源池34中的传输资源发送V2X消息,第二传输资源池34使用常规的第二传输资源获取方式,也即侦听时长T2的先侦听信道后选择传输资源的方式。可选的,T2=1000ms。
此时,第一条件包括:在第二传输资源池中未获得有效的监听结果。
图4示出了本发明一个实施例提供的消息发送方法的流程图。本实施例以该方法应用于图1所示的消息发送系统中来举例说明。该方法包括:
步骤401,接入网设备向终端发送第一配置信息和第二配置信息;
第一配置信息用于确定第一传输资源池,第一传输资源池中的传输资源获取方式是第一传输资源获取方式。可选的,第一传输资源获取方式是:随机选择方式,或,具有侦听时长T1的先侦听信道后选择传输资源的方式,或,CSMA/CA方式。
第二配置信息用于确定第二传输资源池,第二传输资源池中的传输资源获取方式是第二传输资源获取方式。可选的,第二传输资源池获取方式是:具有侦听时长T2的先侦听信道后选择传输资源的方式。
其中,第一传输资源获取方式在选择资源时的选择速度大于第二传输资源获取方式在选择资源时的选择速度。
可选的,接入网设备同时向终端发送第一配置信息和第二配置信息;或者, 接入网设备先向终端发送第一配置信息,再向终端发送第二配置信息;或者,接入网设备先向终端发送第二配置信息,再向终端发送第一配置信息。
可选的,接入网设备通过无线资源控制(英文:Radio Resource Control,简称:RRC)专用信今向终端发送第一配置信息和/或第二配置信息;或者,接入网设备通过系统信息中的系统信息块(System Information Block,SIB)向终端发送第一配置信息和/或第二配置信息;或者,接入网设备通过半静态配置方式向终端发送第一配置信息和/或第二配置信息,半静态配置方式是指在下一次配置之前,本次配置一直有效的配置方式。
可选的,当接入网设备和终端均遵循通信协议所预先约定的配置信息时,本步骤可省略。由终端读取内部的存储器,获取预配置的第一配置信息和/或第二配置信息。
对应地,终端接收接入网设备发送的第一配置信息和第二配置信息。
步骤402,终端根据第一配置信息确定第一传输资源池,根据第二配置信息确定第二传输资源池;
可选的,第一传输资源池中的传输资源与第二传输资源池中的传输资源完全不同;或者,第一传输资源池中的传输资源与第二传输资源池中的传输资源存在一部分相同,存在另一部分不相同;或者,第一传输资源池中的传输资源与第二传输资源池中的传输资源完全相同。
当第一传输资源池中的传输资源与第二传输资源池中的传输资源完全相同时,第一配置信息和第二配置信息是相同的一个配置信息,接入网设备仅需要向终端发送一个配置信息即可。另外,第一传输资源池和第二传输资源池本质上也是相同的一个传输资源池,采用“第一”和“第二”来表述,仅用于表明所使用的传输资源获取方式不同。
本实施例以第一传输资源池中的传输资源与第二传输资源池中的传输资源完全不同来举例说明。
可选的,终端根据第二配置信息确定第二传输资源池后,对第二传输资源池中的传输资源开始连续侦听。
步骤403,终端在确定满足预定条件时,使用第一传输资源获取方式在第一传输资源池中选择第一传输资源;
可选的,预定条件包括如下条件中的至少一种:
1、在第二传输资源池中未获得有效的侦听结果;
终端在第二传输资源池中的侦听时长已经达到1000ms时,若各个传输资源均处于忙碌状态,则不存在处于空闲状态的传输资源。
2、在第二传输资源池中的侦听时长小于T2;
终端对第二传输资源池中的传输资源的侦听时长未达到T2时,无法获得有效的侦听结果。可选的,T2为1000ms。
3、在第二配置信息发生更新后,在第二传输资源池中的侦听时长小于T2;
在第二配置信息发生更新后,终端需要重新确定第二传输资源池。终端对重新确定的第二传输资源池中的传输资源的侦听时长小于T2时,无法获得有效的侦听结果。
4、与接入网设备的同步失效;
终端与接入网设备之间的同步失效时,无法确定传输资源,也就无法对第二传输资源池中的传输资源进行侦听。
5、在同步源发生更新后,根据更新后的同步源时钟在第二传输资源池中的侦听时长小于T2;
示例性的,终端在运行过程中会不断地搜索同步源。当终端搜索到一个新的同步源的优先级高于当前使用的同步源时,终端使用高优先级的同步源的时钟进行同步。终端根据更新后的同步源时钟在第二传输资源池中的侦听时长小于T2时,也无法获得有效的侦听结果。
6、V2X消息的产生时间与第二配置信息的获取时间之差小于预定门限值;
7、在第二传输资源池中未侦听到处于空闲状态的传输资源。
终端在第二传输资源池中的侦听时长已经达到1000ms时,若各个传输资源均处于忙碌状态,则不存在处于空闲状态的传输资源。
当确定满足上述预定条件中的任意一种条件时,终端使用第一传输资源获取方式在第一传输资源池中选择第一传输资源。
步骤404,终端使用第一传输资源发送V2X消息。
步骤405,终端在第二传输资源池获得有效的侦听结果时,使用第二传输资源获取方式在第二传输资源池中选择第二传输资源;
第二传输资源获取方式是:具有侦听时长T2的先侦听信道后选择传输资源的方式。
步骤406,终端使用第二传输资源发送V2X消息。
需要说明的是,步骤405和步骤406是与步骤403和步骤404并列的步骤, 在终端执行步骤403和步骤404时,步骤405和步骤406可以不执行;在终端执行步骤405和步骤406时,步骤403和步骤404可以不执行。可选的,步骤405和步骤406也可以在步骤403和步骤304之前执行,本实施例对此不加以限定。
综上所述,本实施例提供的消息发送方法,由于在选择传输资源时,第一传输资源获取方式的选择速度比第二传输资源获取方式的选择速度快,通过在确定满足预定条件时,使用第一传输资源获取方式在第一传输资源池中选择第一传输资源,使用第一传输资源发送V2X消息,保证了在第二传输资源池中未获得有效的侦听结果的场景下能够正常传输V2X消息。
参考图5,当终端处于第二类特定发送场景(小区切换场景)时,采用第一传输资源获取方式从第一传输资源池选择第一传输资源。假设终端120需要从第一接入网设备142提供的小区切换至第二接入网设备144提供的小区时,由第二接入网设备144向终端配置第一传输资源池52,并由终端在小区切换过程中,采用第一传输资源池52中的第一传输资源发送V2X消息。

可选的,该RRC专用信今包括小区切换配置信息,小区切换配置信息包括第一配置信息,也即第一配置信息作为小区切换配置信息中的子信息项。
可选的,该RRC专用信今包括小区切换配置信息和第一配置信息,小区切换配置信息和第一配置信息相互并列。
对应地,终端接收第一接入网设备发送的RRC专用信今,从RRC专用信今中获取小区切换配置信息和第一配置信息。
可选的,第一配置信息可以包含在小区切换配置信息中,也可以和小区切换配置信息并列包含在RRC专用信今中,两者的包含关系不作限定。

需要说明的是,步骤605和步骤606并无必然的先后顺序关系,本实施例中仅以步骤605在步骤606之前执行来举例说明。步骤605也可以在步骤606之后执行,或者,步骤605和步骤606同时执行,本实施例对此不加以限定。
综上所述,本实施例提供的消息发送方法,由于在选择传输资源时,第一传输资源获取方式的选择速度较快,通过在确定满足预定条件时,使用第一传输资源获取方式在第一传输资源池中选择第一传输资源,使用第一传输资源发送V2X消息,保证了能够在终端的小区切换场景下正常传输V2X消息。
在基于图6实施例提供的可选的实现方式中,第一接入网设备向终端发送第二配置信息;终端根据第二配置信息确定第二传输资源池;在不需要进行小区切换时,终端使用第二传输资源获取方式从第二传输资源池中获取第二传输资源,使用第二传输资源发送V2X消息。
在基于图6实施例提供的可选的实现方式中,终端读取内部存储器,获取预配置的第二配置信息;终端根据第二配置信息确定第二传输资源池;在不需要进行小区切换时,终端使用第二传输资源获取方式从第二传输资源池中获取第二传输资源,使用第二传输资源发送V2X消息。
