Description

基于5G通讯网络的车与车之间的无线支付方法及其系统 技术领域
本发明涉及通信技术，具体涉及一种基于5G通讯网络的车与车之间的无线支付方法及其系统。
背景技术
ETC技术目前普遍应用于高速公路场景中，是欧美日以及中国大力推广的车载收费系统。其通过微波专用短程通信技术实现车载电子标签与ETC专用车道上的微波天线之间的通信，通过互联网技术实现银行后台解算处理。
ETC收费系统由多个子系统组成，包括：自动车辆识别(AVI)系统、自动车辆分型系统(AVC)、逃费抓拍系统(YES)、其它外设系统等。
自动车辆分型系统(AVC)是利用装在车道内和车道周围的各种传感器装置来测定通过车辆的类型，并与车载单元(OBU)存储的车型数据进行核对。逃费抓拍系统(YES)用来抓拍那些未安装有效车载单元并冲闯不停车收费车道的汽车车牌照图像，用于确定逃费车主并通知其应交费用。对于高速不停车收费车道，逃费抓拍系统是必需的。对于低速不停车收费车道，也常常采用高速自动栏杆迫使违章车辆停下。
自动车辆识别系统(AVl)使用安装在门架上或路侧的微波天线查询车载单元中存储的识别信息，如车载单元ID号码、车型、车主等信息，以辨别车辆是否可以通过不停车收费车道。自动车辆识别系统是构成不停车收费车道的最基本系统，通常由车载单元(on—BoardUnit，简称OBU)、路旁单元(RoadSideUnit，简称RSU)、车载单元编程器以及其它设备等组成。
当前ETC支付的主要问题是需要汽车内另行安装设备，且应用场景较少，多用于高速收费站。在用户方面需要申请专用银行卡，在收费站方面需要架设专用通信设备。更为重要的是，ETC技术只考虑了车辆与路边设备进行支付行为的情况，对车辆与车辆之间存在的支付行为并没有加以考虑与进行技术设计。

具体实施方式
下面介绍的是本发明的多个实施例中的一些，旨在提供对本发明的基本了解。并不旨在确认本发明的关键或决定性的要素或限定所要保护的范围。
首先，对于本文中要提到的几个概念进行说明。
(1)5G
第五代行动通信标准，也称第五代移动通信技术，外语缩写：5G。也是4G之后 的延伸，5G网络的理论下行速度为10Gb/s(相当于下载速度1.25GB/s)。
(2)MEC
移动边缘计算(Mobile Edge Computing)，移动边缘计算在距离用户移动终端最近的RAN(无线接入网)内提供IT服务环境以及云计算能力，旨在进一步减小延迟/时延、提高网络运营效率、提高业务分发/传送能力、优化/改善终端用户体验。所以，此处的“边缘(Edge)”所指的即是移动通信基站本身(eNodeB、RNC等)以及无线网络内(比如部署于其中汇聚节点)的各种服务器。部署于无线接入网络边缘的移动边缘计算服务器面向各种上层应用及业务开放实时的无线及网络信息(比如处于移动状态下的用户所在的实时具体位置、基站实时负载情况等)，以便于其提供各种与情境相关的服务。
(3)D2D
Device-to-Device，简称D2D，指设备到设备。Device-to-Device通信是一种在系统的控制下，允许终端之间通过复用小区资源直接进行通信的新型技术，在一定程度上解决无线通信系统频谱资源匮乏的问题。D2D技术可以应用于移动蜂窝网络，以提高资源利用率和网络容量。每一个D2D通信链路占用的资源与一个蜂窝通信链路占用的相等。D2D通信将在宏蜂窝基站的控制下获得通信所需的频率资源和传输功率。

接着，对于本发明的第一实施方式的基于5G通讯网络的车与车之间的无线支付方法的一个实施例进行说明。
本实施例是基于5G通信系统中D2D技术的车辆与车辆之间直接进行无线支付的车载支付方法，该方法适用于车辆在进行车载支付时发现余额不足以支付本次消费而需求向其他车辆进行的借贷的场景。其中为了兼顾方法实用性及全面性，车辆用户与收费用户之间使用的银行允许是多样的，所以方法中引入了第三方平台(这里称为：支付平台)，以完成跨银行之间的交易。
再者，为了方便描述，车辆均处于一般速度行驶状态或静止状态，即行驶 速度低于60km/h，保证可以建立车辆与车辆之间的D2D通信，该D2D通信为基站管理下的D2D通信，双方车辆均满足D2D通信要求，即发送端到接收端的路径损耗小于特定阈值TH1(其取值与车辆所处地理环境有关)，接收端的接收信号强度大于特定阈值TH2(其取值与车辆所处地理环境有关)。车辆的车载终端以固定频率(如1Hz，与GPS型号有关)更新GPS数据。与此同时，本车(即，称为“请求车辆”)绑定支付银行卡以及好友车辆绑定支付银行卡均来自不同的银行，并采用支付平台来实现跨银行交易。
本实施例的基于5G通讯网络的车与车之间的无线支付方法具备包括下述步骤：
(1)本车启动，第一车载终端100工作，第一车载终端包括第一GPS模块110、第一通信模块120以及第一支付模块130。通过第一GPS模块110，本车可以获取时钟信息，从而确保与基站200的同步，建立上行与下行通信链路。本车还可以通过第一GPS模块110获得自身的运动状态信息和位置信息，运动状态信息和位置信息分别指本车的速率、加速度和车辆所处经纬度，这些信息可以帮助车载终端更加准确地筛选支付场景相关信息。
(2)本车的第一车载终端100通过上行链路将车辆识别码(VIN)发送给基站200，基站200通过访问核心网220，将核心网220中存储的本车基本信息载入到基站200的移动边缘计算(MEC)模块230中，该信息包括本车的好友信息，本车信用等级等等相关信息。、
(3)在第一车载终端100检测到本车处于怠速状态时，车辆进入步骤(4)，否则继续执行该检测步骤。
(4)第一车载终端100的支付模块130综合之前收到的支付信息，将其推送至车载显示屏幕，提示用户进行支付。若用户余额足以满足本次支付，则进行支付，返回步骤(3)，否则，执行步骤(5)。
(5)本车通过上行链路将VIN与所需金额这些信息发送至基站200。因为本车收到的支付信息为综合信息，可能存在多个收款方，为了降低数据传输量，并保护本车信息安全，本方法采用本车与好友车辆之间实时交易，并经由本车完成到收款方的支付这一方式。
(6)基站200将这些信息传给移动边缘计算模块230，移动边缘计算模块 230按照VIN提取好友信息，接着，按照VIN完成本车好友车辆的寻找，接着，使用好友车辆的VIN进行信息加密，需要被加密的信息为本车VIN、本车驾驶员信息与本车所需金额。
(7)广播模块240将移动边缘计算模块230加密过的信息进行广播，接收到广播信息的车辆(即相应车辆)上设置的第二车载终端300通过自身VIN进行解密，若信息不能解密成功，则将该信息抛弃。若信息能够解密成功，第二车载终端300将借贷信息在车载显示屏幕上进行显示，借贷信息例如包括本车驾驶员信息以及本车所需金额。
(8)若用户选择将钱借给本车，响应车辆的第二车载终端300第二支付模块320将进行支付，具体为支付给本车所请求金额。响应车辆的第二5G通信模块340将通过上行链路发送同意信息到基站200，同意信息包括同意标识、响应车辆自身VIN、本车VIN以及支付金额等。若基站在设定时间内未接收到同意信息，则进入步骤(12)。
(9)基站200接受并解析同意信息后，将进行两步操作，一是开始建立本车与响应车辆之间的D2D连接，即进入步骤(10)，二是利用本车VIN与响应车辆VIN通过移动边缘计算模块230查找到本车所使用账户信息与响应车辆所使用账户信息，并将这两个账户信息和支付金额信息打包，上传至支付平台400，借助支付平台400完成跨银行转账，即进入步骤(11)。
(10)基站200的D2D建立模块260检测到源端车辆与目的端车辆在相同或邻近小区，且根据最大允许D2D连接数策略，判断该D2D是否可以建立。如果可以，则给该D2D链接分配资源，建立链接；否则进入等待状态。
(11)支付平台400将收到的信息进行解析。通知支付方银行，即响应车辆使用账户所在银行，在相应账户扣除相应金额。同时通知收款方银行，即本车使用账户所在银行，在相应账户增加相应金额。当支付平台400接收到支付方银行的成功反馈与收款方银行的成功反馈后，在将本次支付的成功信息利用基站200发送给响应车辆的第二车载终端300。
(12)请求车辆与其响应车辆之间D2D链接已建立，在响应车辆收到基站200转发的支付成功信息后，响应车辆(即第二车载终端300)将自身车辆账户识别码发送给本车(即第一车载终端100)，第一车载终端100将这部分信息 存入到未完成支付中，在下次支付信推送中进行统一推送。本车根据用户设定，向响应车辆发送约定还款信息，该信息包括具体还款时间、还款方式等相关信息。若响应车辆收到并统一该约定，则发送同意信息至本车，表示约定达成。
(13)交易与约定完成后，第一车载终端100与第二车载终端300通过上行链路通知基站200该D2D链接已断开，资源释放。
(14)基站200将通过下行链路通知本车没有好友响应请求。若本车选择向陌生车辆发起请求，则基站进行信息广播，信息包括请求VIN、车辆所用账户识别码以及所请求金额，进入步骤(8)。若本车选择放弃，则进入步骤(3)，等待下次支付信息推送。
关于选择项陌生车辆进行借贷的情况下，例如包括下述内容：信息加密码为统一设定码，例如，初定为：rent，该设定码为所有车辆共享信息，所有车辆均可以解密由rent作为密钥加密的信息；车辆可以预先设定是否借款给陌生车辆，若设定为否，则车辆不使用rent进行信息解密，陌生车辆的借款信息将会被默认为无关信息丢弃，若设定为是，则车辆可解密陌生车辆的借款信息，其推送流程与向好友借款一致；针对还款问题，本系统中，支付平台400设置为可出具电子借款账单供相关事宜使用。
接着，对于本发明的第二实施方式的基于5G通讯网络的车与车之间的无线支付方法进行说明。该第二实施方式中，替代基站广播寻找小区的目标车辆(响应车辆)的方式而采用车辆本身进行广播寻找目标车辆。

支付实现步骤S50：响应车辆基于请求信息生成支付信息并发送至基站，由基站将支付信息发送到支付平台，支付平台返回支付结果到响应车辆；以及
D2D通信步骤S60：基站为请求车辆和响应车辆分配D2D通信通道，响应车辆和请求车辆通过D2D通信通道进行通信。
当好友车辆为n辆的情况下，循环进行所述加密广播步骤S30，直到某一个好友车辆利用自己的车辆信息成功解码广播信息为止。
作为对于支付信息进行加密的好友车辆的车辆信息，采用好友车辆的VIN。
