Description

设备到设备D2D的通信方法、装置和车联网终端 技术领域
本公开涉及车联网通信技术领域，例如涉及一种设备到设备D2D的通信方法、装置和车联网终端。
背景技术
设备到设备D2D(Device-to-Device)通信技术是指基于D2D技术实现的用户设备(简称，D2D用户设备)之间进行数据通信时，可不通过网络基础设施的中转，设备之间可直接进行通信，这样的通信不需要网络基础设施的参与，减少了网络基础设备的负担，减少用户设备的电池功耗、提高数据速率，并改善网络基础设施的鲁棒性，很好地满足上述高数据速率业务和邻近服务的要求。
车联网通信系统是基于无线通信技术获取车辆和道路的信息，通过车车、车路信息交互和共享实现车辆和基础设施之间智能协同与配合，达到优化利用系统资源、提高道路交通安全、缓解交通拥堵的目的。车联网通信系统是智能交通领域重要的基础技术，具有高度的实际应用价值，因而受到很多汽车厂商的重点关注。
在车联网通信系统中的相关技术中，大部分道路突发事故处理方式仅为事故告警牌提示，或由交警现场指挥，容易造成大面积、长时间的交通拥塞。这主要是由于车辆在行驶的过程中，不能及时将自身的相关信息(例如位置信息和运行状态)告知车辆网通信系统或者其他与该车辆相邻的车辆，从而造成其他车辆不知前方道路发生事故，从而驾驶员不能及时调整自己的行驶路线，进而造成了道路拥堵。

具体实施方式
下面详细描述本公开的实施例，实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开。
下面参考附图描述本公开实施例的设备到设备D2D的通信方法、装置和车联网终端。
图1是本公开一个实施例的设备到设备D2D的通信方法的流程图。
如图1所示，该设备到设备D2D的通信方法包括以下几个步骤：
S110，车联网终端根据接收到的资源配置信息设定车联网终端的D2D资源的发送周期和发送D2D周期性消息的时隙。
其中，D2D周期性消息是根据车联网功能需求所需要周期性发送的信息，D2D周期性消息可以是包括车辆的位置信息、运行状态信息等，在实际应用过程中，还可以根据车联网功能需求对周期性发送的信息进行调整。
在实际应用中，在每个周期中可以固定发送一次或者多次D2D周期性信息，其中，在每个周期中发送D2D周期性信息的次数与时隙的个数相同。
其中，车辆的运行状态信息可以是包括车辆的车速、加速度、减速度、故障信息等。
可选地，在使用车联网终端的过程中，可通过多种方式设置车联网终端D2D资源的发送周期和车联网终端发送D2D周期性消息的时隙，可根据实际场景需求进行设置，举例说明如下：
作为一种示例，车联网终端可通过与具有管理功能的车联网终端(简称，管理车联网终端)进行通信交互，并由管理车联网终端发送资源配置信息，然 后，车联网终端根据接收到的资源配置信息设置自身发送D2D资源的发送周期和发送D2D周期性消息的时隙。
在车队场景中，车队中的管理者可通过自身使用的车联网终端与车队中的其他车联网终端建立通信连接，管理者的车联网终端中显示车队中其他车联网终端的相关信息(例如，车联网终端的名称信息)，为了使得在车队行驶过程中，随时了解车队中其他车辆的运行状况，避免车队中的车辆出现失去联系而车队中的成员不知道情况的发生，管理者可通过自身使用的车联网终端设置车队中每个车辆发送D2D周期性信息的时隙和D2D资源的发送周期，即，车队中每个车联网终端发送D2D周期性信息的时隙是不同的，每个车联网终端发送D2D资源的发送周期是相同的，并将所设置的相关信息发送至车队中对应的车联网终端。
其中，D2D资源的发送周期是车联网通信系统预先设置的时间。
例如，车队总共有4辆车，这四辆车所对应的车联网终端分别为车联网终端A、车联网终端B、车联网终端C和车联网终端D，假设车联网终端A的使用者为管理者，此时，车联网终端A可与车联网终端B、车联网终端C和车联网终端D建立通信连接，并通过车联网终端A为自身设置对应的发送D2D周期性信息的第一时隙和D2D资源的发送周期，并为车联网终端B设置车联网终端B对应的发送D2D周期性信息的第二时隙和D2D资源的发送周期，为车联网终端C设置车联网终端C对应的发送D2D周期性信息的第三时隙和D2D资源的发送周期，为车联网终端D设置车联网终端D对应的发送D2D周期性信息的第四时隙和D2D资源的发送周期，由此，为车队中的每个车辆设置了每个车辆各自发送D2D周期性信息的时隙，避免了多个车辆发送D2D周期性信息时可能造成冲突情况的发生。其中，车队中的管理者可将D2D周期性信息发送至车队中的每个车辆上，也可以根据需求将D2D周期性信息预先发送至指定的车辆中。
作为另一种示例，可以由网络侧对车联网终端中的发送周期和发送D2D周期性消息的时隙进行设定。
可选地，在车联网终端与车联网通信系统建立通信连接后，车联网通信系统中的网络侧可根据车联网通信系统中预先设置的资源配置信息为当前接入的车联网终端设置发送D2D资源的发送周期和D2D周期性消息的时隙。
S120，针对每个发送周期，在监控到当前发送周期中D2D周期性消息的时隙到达时，车联网终端发送当前D2D周期性消息至接收方。
在每个周期中D2D周期性消息的时隙，车联网终端获取车辆的当前位置信 息和当前运行状态信息中的至少一个，并将当前位置信息和当前运行状态信息中的至少一个发送至接收方。
其中，在不同应用场景中，该实施例中的接收方是不同的。
例如，在车队场景中，接收方为车队中具有管理能力的车联网终端。
再例如，在普通的道路场景中，接收方为设置在道路旁的路边单元，该路边单元可以将所接收到的D2D周期性信息发送至交通指挥中心，以使交通指挥中心对车辆的位置信息进行监控，并在监控到车辆前方出现拥堵时，给车辆中的车联网终端发送拥堵提醒提示，以使驾驶者可根据提示信息调整自己的驾驶路线。
在本公开的一个实施例中，为了使得接收方可以识别信息的发送方，在向接收方发送车辆的当前位置信息和当前运行状态信息中的至少一个的过程中，车联网终端在发送当前位置信息和当前运行状态信息中的至少一个的同时，还可以发送自身的标识信息。接收方通过标识信息确定D2D周期性消息的发送方。
在本公开的一个实施例中，为了使得接收方可以识别出所接收的消息是D2D周期性消息，可以为该D2D周期性消息设置类型标识，接收方可以通过类型标识识别出所接收到的消息为D2D周期性消息。例如，车联网终端在发送D2D周期性消息时，可以为D2D周期性消息设置对应的消息类型头，接收方可以在识别出接收到的消息中包含D2D周期性消息对应的消息类型头时，确定该消息为D2D周期性消息。
综上可以看出，该实施例的车联网终端周期性地发送D2D周期性消息，使得接收方可以根据接收到的D2D周期性消息来确定车联网终端所在车辆的位置信息和运行状态信息。
根据本公开实施例的设备到设备D2D的通信方法，根据接收到的资源配置信息设置D2D资源的发送周期和发送D2D周期性消息的时隙，并在每个周期的固定时隙发送D2D周期性消息给接收方，由此，实现了车联网终端周期性地发送D2D周期性消息，使得接收方可以根据接收到的D2D周期性消息为后续的车联网业务(例如，车辆预警和车辆故障分析)提供可靠的依据。例如在D2D周期性中包含车辆的位置信息和运行状态信息时，接收方根据位置信息对车辆的位置进行监控，并通过运行状态信息及时了解车联网终端所在的车辆的运行状况。
基于图1所示的基础上，在车联网终端向接收方发送D2D周期性信息时，车联网终端还可以接收发送方终端所发送的其他车辆的位置信息也就是说，车联 网终端还可以接收其他车辆的位置信息，以通过其他车辆的位置信息进行碰撞预警、变道预警等，或者在车队场景中，可将其他车辆的位置信息提供给用户，以使用户了解车队中其他车辆的位置信息。
图2是本公开另一个实施例的设备到设备D2D的通信方法的流程图。
如图2所示，该设备到设备D2D的通信方法包括以下几个步骤：
S201，车联网终端根据接收到的资源配置信息设定车联网终端的D2D资源的发送周期和发送D2D周期性消息的时隙。
其中，D2D周期性消息是根据车联网功能需求所需要周期性发送的信息，D2D周期性消息可以是包括车辆的位置信息、运行状态信息等，在实际应用过程中，还可以根据车联网功能需求对周期性发送的信息进行调整。
在实际应用中，在每个周期中可以固定发送一次或者多次D2D周期性信息，其中，在每个周期中发送D2D周期性信息的次数与时隙的个数相同。
其中，车辆的运行状态信息可以是包括车辆的车速、加速度、减速度、故障信息等。
可选地，在使用车联网终端的过程中，可通过多种方式设置车联网终端D2D资源的发送周期和车联网终端发送D2D周期性消息的时隙，可根据实际场景需求进行设置，举例说明如下：
作为一种示例，车联网终端可通过与具有管理功能的车联网终端(简称，管理车联网终端)进行通信交互，并由管理车联网终端发送资源配置信息，然后，车联网终端根据接收到的资源配置信息设置自身发送D2D资源的发送周期和发送D2D周期性消息的时隙。
在车队场景中，车队中的管理者可通过自身使用的车联网终端与车队中的其他车联网终端建立通信连接，管理者的车联网终端中显示车队中其他车联网终端的相关信息(例如，车联网终端的名称信息)，为了使得在车队行驶过程中，随时了解车队中其他车辆的运行状况，避免车队中的车辆出现失去联系而车队中的成员不知道情况的发生，管理者可通过自身使用的车联网终端设置车队中每个车辆发送D2D周期性信息的时隙和D2D资源的发送周期，即，车队中每个车联网终端发送D2D周期性信息的时隙是不同的，每个车联网终端发送D2D资源的发送周期是相同的，并将所设置的相关信息发送至车队中对应的车联网终端。
其中，需要理解的是，D2D资源的发送周期是车联网通信系统预先设置的 时间。
例如，车队总共有4辆车，这四辆车所对应的车联网终端分别为车联网终端A、车联网终端B、车联网终端C和车联网终端D，假设车联网终端A的使用者为管理者，此时，车联网终端A可与车联网终端B、车联网终端C和车联网终端D建立通信连接，并通过车联网终端A为自身设置对应的发送D2D周期性信息的第一时隙和D2D资源的发送周期，并为车联网终端B设置车联网终端B对应的发送D2D周期性信息的第二时隙和D2D资源的发送周期，为车联网终端C设置车联网终端C对应的发送D2D周期性信息的第三时隙和D2D资源的发送周期，为车联网终端D设置车联网终端D对应的发送D2D周期性信息的第四时隙和D2D资源的发送周期，由此，为车队中的每个车辆设置了每个车辆发送D2D周期性信息的时隙，避免了多个车辆发送D2D周期性信息时可能造成冲突情况的发生。其中，需要理解的是，车队中的管理者可将D2D周期性信息发送至车队中的每个车辆上，也可以根据需求将D2D周期性信息预先发送至指定的车辆中。
作为另一种示例，可以由网络侧对车联网终端中的发送周期和发送D2D周期性消息的时隙进行设定。
可选地，在车联网终端与车联网通信系统建立通信连接后，车联网通信系统中的网络侧可根据车联网通信系统中预先设置的资源配置信息为当前接入的车联网终端设置发送D2D资源的发送周期和D2D周期性消息的时隙。
S202，针对每个发送周期，在监控到当前发送周期中D2D周期性消息的时隙到达时，车联网终端发送当前D2D周期性消息至接收方。
在每个周期中的时隙，车联网终端获取车辆的当前位置信息和当前运行状态信息中的至少一个，并将当前位置信息和当前运行状态信息中的至少一个发送至接收方。
其中，在不同应用场景中，该实施例中的接收方是不同的。
例如，在车队场景中，接收方为车队中具有管理能力的车联网终端。
再例如，在普通的道路场景中，接收方为设置在道路旁的路边单元，该路边单元可以将所接收到的D2D周期性信息发送至交通指挥中心，以使交通指挥中心对车辆的位置信息进行监控，并在监控到车辆前方出现拥堵时，给车辆中的车联网终端发送拥堵提醒提示，以使驾驶者可根据提示信息调整自己的驾驶路线。
在本公开的一个实施例中，为了使得接收方可以识别信息的发送方，在向 接收方发送车辆的当前位置信息和当前运行状态信息中的至少一个的过程中，车联网终端在发送当前位置信息和当前运行状态信息中的至少一个的同时，发送自身的标识信息。接收方通过标识信息确定D2D周期性消息的发送方。
在本公开的一个实施例中，为了使得接收方可以识别出所接收的消息是D2D周期性消息，可以为该D2D周期性消息设置类型标识，接收方可以通过类型标识识别出所接收到的消息为D2D周期性消息。例如，车联网终端在发送D2D周期性消息时，可以为D2D周期性消息设置对应的消息类型头，接收方可以在识别出接收到的消息中包含D2D周期性消息对应的消息类型头时，确定该消息为D2D周期性消息。
S203，在车联网终端发送非周期性消息时，车联网终端选择与D2D周期性消息所使用时隙外的其他时隙发送非周期性消息。
也就是说，在D2D资源的发送周期中，车联网终端除了在固定时隙向接收方发送D2D周期性消息外，车联网终端还可以发送非周期性消息，例如，用户还可以根据需求通过车联网终端发送非周期性消息。
其中，非周期性消息是指不需要向接收方周期性发送的消息，非周期性消息可以是包括视频、音频、图片和文字，还可以包括预警信息。
再例如，车联网终端可以发送车辆的预警信息。
车联网终端在每个发送周期中的非周期消息时隙可以发送非周期性消息，即，车联网终端在不需要发送D2D周期性消息的时隙可以发送不需要周期性发送的消息。
其中，非周期消息时隙是指不需要发送D2D周期性消息的时隙。
例如，一个周期分为十个时隙，如果根据资源配置消息确定第二个时隙发送D2D周期性消息，则这个周期中剩余的时隙均是非周期消息时隙。
举例而言，在一个车队中，在车队停在一个位置休息时，驾驶车辆A的第一用户可选择与D2D周期性消息所使用时隙外的其他时隙通过第一车联网终端向第二车联网终端发送一个小视频，由此，使得车队中的任意两个车辆之间可以实现资源的共享。
综上可以看出，该实施例的车联网终端在每个周期的固定时隙发送D2D周期性，在每个周期的其他时隙中，用户可根据需求通过车联网终端发送视频、音频等不需要周期性发送的消息，以使车与车之间的资源共享。
在本公开的一个实施例中，如果接收方在当前周期中未接收到车联网终端 发送的D2D周期性信息，则接收方获取该车联网终端上一个周期发送的D2D周期性信息，并根据上一个周期中的D2D周期性信息确定该车联网终端可能的位置信息，并向该位置信息周围的其他车联网终端发送消息，以使其他车联网终端根据该信息与该车联网终端进行联系，以确定该车联网终端所在车辆的运行状态信息。
为了实现上述实施例，本公开还提出一种设备到设备D2D的通信装置。
图3是本公开一个实施例的设备到设备D2D的通信装置的结构示意图。该设备到设备D2D的通信装置位于车联网终端中，如图3所示，该设备到设备D2D的通信装置包括设定模块110和第一处理模块120，其中：
设定模块110，设置为根据接收到的资源配置信息设定车联网终端的D2D资源的发送周期和发送D2D周期性消息的时隙。
其中，D2D周期性消息是根据车联网功能需求所需要周期性发送的信息，D2D周期性消息可以是包括车辆的位置信息、运行状态信息等，在实际应用过程中，还可以根据车联网功能需求对周期性发送的信息进行调整。
需要理解的是，在实际应用中，在每个周期中可以固定发送一次或者多次D2D周期性信息，其中，在每个周期中发送D2D周期性信息的次数与时隙的个数相同。
其中，车辆的运行状态信息可以是包括车辆的车速、加速度、减速度、故障信息等。
第一处理模块120，设置为针对每个发送周期，在监控到当前发送周期中D2D周期性消息的时隙到达时，发送当前D2D周期性消息至接收方。
在每个周期中的时隙，第一处理模块120获取车辆的当前D2D周期性消息，并将当前D2D周期性消息发送至接收方。
在本公开的一个实施例中，为了使得接收方可以识别信息的发送方，在向接收方发送车辆的当前位置信息和当前运行状态信息中的至少一个的过程中，第一处理模块120在发送当前位置信息和当前运行状态信息中的至少一个的同时，还可以发送自身的标识信息。接收方通过标识信息确定D2D周期性消息的发送方。
综上可以看出，该实施例的车联网终端周期性地发送D2D周期性消息，使得接收方可以根据接收到的D2D周期性消息来确定车联网终端所在车辆的位置 信息和运行状态信息。
前述对设备到设备D2D的通信方法实施例的解释说明也适用于该实施例的设备到设备D2D的通信装置，其实现原理类似，此处不再赘述。
根据本公开实施例的设备到设备D2D的通信装置，设定模块根据接收到的资源配置信息设置D2D资源的发送周期和发送D2D周期性消息的时隙，并第一处理模块在每个周期的固定时隙发送D2D周期性消息给接收方，由此，实现了车联网终端周期性地发送D2D周期性消息，使得接收方可以根据接收到的D2D周期性消息为后续的车联网业务(例如，车辆预警和车辆故障分析)提供可靠的依据。尤其在D2D周期性中包含车辆的位置信息和运行状态信息时，接收方根据位置信息对车辆的位置进行监控，并通过运行状态信息及时了解车联网终端所在的车辆的运行状况。
在本公开的一个实施例中，在如图3所示的基础上，如图4所示，该装置还可以包括第二处理模块130，该第二处理模块130设置为在发送非周期性信息时，选择与D2D周期性消息所使用时隙外的其他时隙发送所述非周期性消息。
其中，非周期性消息是指不需要向接收方周期性发送的消息，非周期性消息可以是包括视频、音频、图片和文字，还可以包括预警信息。
也就是说，第二处理模块130在每个周期中的非周期消息时隙可以发送非周期性消息，即，车联网中可以发送不需要周期性发送的消息。
其中，非周期消息时隙是指不需要发送D2D周期性消息的时隙。
例如，一个周期分为十个时隙，如果根据资源配置消息确定第二个时隙发送D2D周期性消息，则这个周期中剩余的时隙均是非周期消息时隙。
综上可以看出，第二处理模块130在每个周期的固定时隙发送D2D周期性，在每个周期的其他时隙中，用户可根据需求通过车联网终端向接收方发送视频、音频等不需要周期性发送的消息，以使车与车之间的资源共享。
其中，非周期性消息是指不需要向接收方周期性发送的消息，非周期性消息可以是包括视频、音频、图片和文字，还可以包括预警信息。
在本公开的一个示例中，如图4所示，该装置还可以包括接收模块140，该接收模块140设置为接收发送方终端所发送的其他车辆的位置信息，以通过其他车辆的位置信息进行碰撞预警、变道预警等，或者将其他车辆的位置信息提供给用户，以使用户了解车队中其他车辆的位置信息。

根据本公开实施例的车联网终端，根据接收到的资源配置信息设置D2D资源的发送周期和发送D2D周期性消息的时隙，并在每个周期的固定时隙发送D2D周期性消息给接收方，由此，实现了车联网终端周期性地发送D2D周期性消息，使得接收方可以根据接收到的D2D周期性消息为后续的车联网业务(例如，车辆预警和车辆故障分析)提供可靠的依据。例如在D2D周期性中包含车辆的位置信息和运行状态信息时，接收方根据位置信息对车辆的位置进行监控，并通过运行状态信息及时了解车联网终端所在的车辆的运行状况。
本实施例提出了一种非暂态计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令用于执行上述任一实施例所述的设备到设备D2D的通信方法。

工业实用性
本公开提供的设备到设备D2D的通信方法，实现了车联网终端根据接收到的资源配置信息设置D2D资源的发送周期和发送D2D周期性消息的时隙，并在每个周期的固定时隙发送D2D周期性消息给接收方，由此，实现了车联网终端周期性地发送D2D周期性消息，使得接收方可以根据接收到的D2D周期性消息为后续的车联网业务(例如，车辆预警和车辆故障分析)提供可靠的依据。尤其在D2D周期性中包含车辆的位置信息和运行状态信息时，接收方根据位置信息对车辆的位置进行监控，并通过运行状态信息及时了解车联网终端所在的车辆的运行状况。
