 本发明的实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，均属于本发明保护的范围。
请参阅图1，图1是本发明提供的通信终端的实施例的结构示意图。通信终端10包括一块基带板卡11、一块射频板卡12和电源13，基带板卡11包括处理器111，可以运行OAI软件，用于实现数字信号处理功能，在本实施场景中，处理器111为Intel通用处理器，在其他实施场景中，处理器111还可以是AMD处理器。在本实施场景中，基带板卡上的OAI软件经过编辑，可以支持D2D的相关功能，因此处理器111可以通过运行该OAI软件，实现D2D的相关功能。射频板卡12耦接基带板卡11，用于完成射频信号的发送、接收或同步以及信号的模拟/数字转换工作。在本实施场景中，射频板卡12集成Lime公司的收发器（Transceiver），通过这个Transceiver完成上述工作。电源13同时耦接基带板卡11和射频板卡12，用于给通信终端10的工作提供工作电压。
在本实施场景中，通信终端10是基于微型电信计算架构平台（Micro TCA，Micro Telecom Computing Architecture），该平台可扩展性强、稳定性高、是基于开源软件搭建的软硬结合的5G通用开发、测试、应用平台。且该平台集成度高，体积小，使用灵活。在其他实施场景中，还可以基于ATCA（先进的电信计算平台，Advanced Telecom Computing Architecture）、TCA（电信计算平台，Telecom Computing Architecture）。
基于Micro TCA的通信终端10包括一块基带板卡11和一块射频板卡12，现有的Micro TCA外壳有5个插槽，可以支持插入5块基带板卡和\或射频板卡。在本实施场景中，通信终端10基于SISO（单入单出，single input single output）的设计，需要一块基带板卡11和一块射频板卡12，在其他实施场景中，可能需要支持MIMO（多入多出，Multiple Input Multiple Output）则需要至少2块射频板卡。在本实施场景中，系统带宽在5M~10M之间，需要一块基带板卡11，在其他实施场景中，可能支持20MHz及以上的系统带宽，则需要2块或者更多块的基带板卡11。
在本实施场景中，基带板卡是AMC（自适应调制编码，Adaptive Modulation and Coding）板卡，AMC可以根据无线信道变化选择合适的调制和编码方式，根据用户瞬时信道质量状况和目前资源选择最合适的链路调制和编码方式，使用户达到尽量高的数据吞吐率。射频板卡是FMC（FPGA 夹层卡，FPGA Mezzanine Card）板卡，FMC板卡是一个应用范围、适应环境范围和市场领域范围都很广的通用模块。FMC板卡支持高达 10 Gb/s 的信号传输速率，消除了协议开销，可以避免时延问题，通过简化系统设计降低了功耗，缩短了工程设计时间，并缩减了IP 核及材料成本。
在本实施场景中，基带板卡11的接口和射频板卡12的接口支持多种高速通信协议，如RapidIO（包交换互联）协议， PCIE（高速串行计算机扩展总线标准，Peripheral Component Interconnect Express）等协议。在其他实施场景中，还可以支持以太网结构，Aurora等协议。
基带板卡11集成了现场可编程门（FPGA，Field－Programmable Gate Array）、阵列数字信号处理器（DSP，Digital Signal Processing,）和系统级芯片（SOC，System-on-a-Chip）中的至少一项，基带板卡11可以通过现场可编程门、阵列数字信号处理器或者系统级芯片实现数字信号处理功能。在本实施场景中，基带板卡11集成高性能FPGA芯片，部分物理层功能可以平移到FPGA中完成，这样通信终端10不仅支持物理层和MAC，RLC等层在不同物理实体中运行，同时也支持物理层中的不同模块在处理器111和FPGA之间无缝链接，以支持5G的高速率需求。
在本实施场景中，处理器111包括两个核心，能够支持20MHz TDD（时分双工，Time Division Duplexing)）LTE（长期演进，Long Term Evolution）协议的处理，在其他实施场景中，处理器111包括四个核心，四核处理器可以提供更高的数据吞吐量，加快数据处理的速度。
在本实施场景中，处理器111为Intel通用处理器，且处理器111包括两个核心。基于Intel通用处理器架构的通信终端10上运行的OAI软件的设计原则是在满足协议中对实时性要求的基础上，最大化的利用多核处理器的处理能力。为此，在OAI软件的设计还有以下特征：
1)该OAI软件同时支持静态调度和动态调度法。静态调度算法是调度之前制定好调度策略，调度过程中按照预先制定的策略进行调度，调度过程中不考虑当前各服务器、网关或链路的实际负载情况及可负载的能力。由于调度不随着当前的负载情况改变而改变，因此称为静态调度算法。算法特点是实现简单、调度快捷。静态调度算法主要代表有：轮转调度算法、加权轮转调度算法、随机调度算法、加权随机调度算法、基于源地址哈希调度算法、基于目的地址哈希调度算法、基于源地址端口哈希调度算法。
动态调度通常是指在调度环境和任务存在不可预测扰动情况下所进行的调度。与静态调度相比，动态调度能够针对实际情况产生更具可操作性的决策方案。动态调度的实现方式有两种：一是事先不存在静态调度方案，直接按照现有的状况以及相关信息，使用某种计算方法，确定不同程序的优先级，即实时调度；二是在已有静态调度方案的基础上，根据现场状态，及时进行静态调度方案的调整，确定不同程序的优先级，此种方式常常被称作“重调度”。
本发明中的OAI软件同时支持静态调度和动态调度，可以有效的节省工作时间，提升工作效率。
2) 该OAI软件根据每个任务的属性可以快速高效地对任务进行切分，并且灵活地将任务分配给不同的线程。
3) 该OAI软件为每个子任务标记时间戳。任务管理器需要给每个子任务分配一个时间预算。软件在处理流程中会给子任务标记时间戳，并与分配的时间预算进行比较，以此来决定是继续执行还是提前终止。软件会首先处理高优先级的任务，然后在尽最大的努力处理其他任务。例如，在LTE终端接收端的物理层，首先进行IFFT（快速傅里叶逆变换，,Inverse Fast Fourier Transform）运算，然后逐一对控制信道PDCCH（物理下行控制信道，Physical Downlink Control Channel）进行解码，最后再根据剩余的时间对数据信道PDSCH（物理下行共享信道，Physical Downlink Share Channel）进行处理。
4)任务和线程的优先级分配。给通信终端10上运行的OAI程序不同的子程序分配不同的优先级。例如，为了保证通信协议的正常运转，控制信道以及控制处理流程的相关程序必须具有最高的优先级。也有一些任务并没有严格的实时性要求，因此可以给其分配较低的优先级，在高优先级的任务处理完毕后再处理低优先级的任务。例如，PRACH（物理随机接入信道，Physical Random Access Channel）信道中的响应就可以在一个较长的时间周期内去处理。
通过上述描述可知，本实施例中的通信终端基于微型电信计算架构平台，通信终端的处理器通过运行经过编辑后的OAI软件，实现D2D的相关功能，通信终端的体积小，携带方便，且可以满足5G的高速率需求。
请参阅图2，图2是本发明提供的通信终端的第二实施例的结构示意图。通信终端20包括两个基带板卡21、23。在一个具体的实施场景中，有新功能需要扩展时，一块基带板卡21可能无法满足工作需求，此时可以添加一块新的基带板卡23，基带板卡23上集成阵列数字信号处理器（DSP，Digital Signal Processing,）和系统级芯片（SOC，System-on-a-Chip）中的至少一项，可以用于后续使用中新功能的扩展。基带板卡21和23分别包括处理器211和231。基带板卡21和基带板卡23之间通过载波集线器24连接，载波集线器24通过外设部件高速互连接口或高速串行接口处理基带板卡21和基带板卡23之间的数据交换。本实施场景中，有两块基带板卡，在其他实施场景中，可以有3块、4块或者5块基带板卡，这些基带板卡之间都通过载波集线器24处理彼此之间的数据交换任务。射频板卡22耦接基带板卡21和基带板卡23，用于完成射频信号的发送、接收或同步以及信号的模拟/数字转换工作。电源25同时耦接基带板卡21、基带板卡23和射频板卡22，用于给通信终端10的工作提供工作电压。
在本实施场景中，基带板卡21和23与本发明提供的通信终端的第一实施例的基带板卡11的结构与功能基本一致，射频板卡22与本发明提供的通信终端的第一实施例的射频板卡12的结构与功能基本一致，电源25与本发明提供的通信终端的第一实施例的电源13的结构与功能基本一致，且基带板卡21和23、射频板卡22与电源25之间的连接关系与本发明提供的通信终端的第一实施例中的基带板卡11、射频板卡12和电源13的连接关系基本一致。此处不再赘述。
通过上述描述可知，本实施例中的通信终端基于微型电信计算架构平台，使得该通信终端体积小巧，便携性高。通信终端的处理器通过运行经过编辑后的OAI软件，实现D2D的相关功能，在多个基带板卡之间用具有高速接口的载波集线器处理数据传输的工作，可扩展性强，可以满足5G的高速率需求。
请结合参阅图3、图4，图3是本发明提供的通信测试方法的第一实施例的结构示意图，图4是本发明提供的通信测试方法的第一实施例的流程示意图。本发明提供的通信测试方法包括以下步骤：
S101：全部通信终端与基站建立无线连接；
D2D连接状态下的通信终端需要接受基站的控制，基站可以对通信终端之间的通信链路分配资源，以使得通信资源得到合理应用。在一个具体的实施场景中，通信终端30的射频板卡32、通信终端40的射频板卡42、通信终端50的射频板卡52和通信终端60的射频板卡62与基站70建立连接。且通信终端30的射频板卡32和通信终端40的射频板卡42之间建立连接、通信终端40的射频板卡42和通信终端50的射频板卡52之间建立连接、通信终端50的射频板卡52和通信终端60的射频板卡62之间建立连接。基站70根据通信终端30、通信终端40、通信终端50和通信终端60需要传输的数据量和数据类型，以及通信终端30的射频板卡32和通信终端40的射频板卡42之间、通信终端40的射频板卡42和通信终端50的射频板卡52之间、通信终端50的射频板卡52和通信终端60的射频板卡62之间的通信链路的通信质量，给通信终端30、通信终端40、通信终端50和通信终端60分配合适的通信资源。
在本实施场景中，为了可以更加直观的观察测量结果，基站70、通信终端30、通信终端40、通信终端50和通信终端60分别连接控制设备81、控制设备82、控制设备83、控制设备84和控制设备85，用于控制并反馈基站70、通信终端30、通信终端40、通信终端50和通信终端60的工作状态。在通信终端30的射频板卡32、通信终端40的射频板卡42、通信终端50的射频板卡52和通信终端60的射频板卡62与基站70建立连接后，操作基站70的控制设备，使得基站70、通信终端30、通信终端40、通信终端50和通信终端60进入多跳通信工作模式。在本实施场景中，为了便于实验数据的统计与比对，本实施场景中，多跳通信的路由是固定的，
例如通信终端30→通信终端40 →通信终端50→通信终端60。
S102：第一通信终端将测试信息发送给第二通信终端；
在一个具体的实施场景中，测试信息是一段视频，在其他实施场景中，测试信息也可以是一段音频，或者一幅图片，或者其他多媒体文件。
通信终端30将需要传输的视频在与其相连接的控制设备82上播放，并将该视频数据通过射频板卡32发送给通信终端40。
S103：所述第二通信终端将接收到的所述测试信息发送给第三通信终端；
通信终端40通过射频板卡42接收由通信终端30发送的视频数据，经过基带板卡41处理该视频数据，并在与自身相连接的控制设备83上播放该视频。同时通信终端40作为中继通过射频板卡42向通信终端50发送接收到的视频数据。
S104：所述第三通信终端将接收到的所述测试信息发送给第四通信终端；
通信终端50通过射频板卡52接收由通信终端40发送的视频数据，经过基带板卡51处理该视频数据，并在与自身相连接的控制设备85上播放该视频。同时通信终端50作为中继通过射频板卡52向通信终端60发送接收到的视频数据。

通信终端60通过射频板卡62接收由通信终端50发送的视频数据，经过基带板卡61处理该视频数据，并在与自身相连接的控制设备85上播放该视频。此时可以通过控制设备85播放的视频的流畅程度和视频质量直观检测出D2D传输的通信质量。
在其他实施场景中，还可以通过控制设备85检测并显示通信终端60的实时等效SNR（信噪比，Signal to noise ratio）或者显示吞吐量曲线，通过实时等效SNR或者显示吞吐量曲线评价D2D传输的通信质量。
在其他实施场景中，可以检测控制设备83、控制设备84播放的视频的流畅程度和视频质量直观检测出D2D传输过程中的每一段传输链路的通信质量。同理，还可以通过控制设备83、控制设备84检测并显示通信终端60的实时等效SNR（信噪比，Signal to noise ratio）或者显示吞吐量曲线，通过实时等效SNR或者显示吞吐量曲线评价D2D传输过程中的每一段传输链路的通信质量。
在本实施场景中，通信终端30、通信终端40、通信终端50和通信终端60是图1所示的通信终端，在其他实施例中，通信终端30、通信终端40、通信终端50和通信终端60中的一个或者多个还有可能是图2所示的通信终端。
通过上述描述可知，本实施例通过使用基于微型电信计算架构平台的通信终端进行D2D的通信质量测试，通过视频播放质量、实时信噪比和吞吐量曲线中的至少一项检测D2D通信质量，方法简单易行。
请结合参阅图5、图6，图5是本发明提供的通信测试方法的第二实施例的结构示意图，图6是本发明提供的通信测试方法的第二实施例的流程示意图。本发明提供的通信测试方法包括以下步骤：

S202：第一通信终端将测试信息发送给第二通信终端；
S203：所述第二通信终端将接收到的所述测试信息发送给第三通信终端；
S204：所述第三通信终端将接收到的所述测试信息发送给第四通信终端；
S205：检测所述第四通信终端接收到的测试信息、实时信噪比和吞吐量曲线中的至少一项；
步骤S201~步骤S205与本发明提供的通信测试方法的第一实施例中的步骤S101~步骤S105基本一致，此处不再赘述。

在本实施场景中，模拟信号阻挡91、模拟信号阻挡92和模拟信号阻挡93为模拟行人阻挡，在其他实施场景中模拟信号阻挡91、模拟信号阻挡92和模拟信号阻挡93还可以是金属网阻挡。
S207：检测所述第四通信终端接收到的测试信息、实时信噪比和吞吐量曲线中的至少一项与未做模拟信号阻挡时相比是否下降；
与步骤S205类似，在控制设备84上播放该视频。此时可以通过控制设备85播放的视频的流畅程度和视频质量直观检测出D2D传输的通信质量。还可以通过控制设备85检测并显示通信终端60的实时等效SNR（信噪比，Signal to noise ratio）或者显示吞吐量曲线，通过实时等效SNR或者显示吞吐量曲线评价D2D传输的通信质量。
将经过模拟信号阻挡91、模拟信号阻挡92和模拟信号阻挡93阻挡后控制设备85播放视频的流程程度和视频质量、时等效SNR以及显示吞吐量曲线与步骤S205中得到的结果进行对比，得出模拟信号阻挡91、模拟信号阻挡92和模拟信号阻挡93对D2D通信质量的影响程度。
在其他实施场景中，可以检测控制设备83、控制设备84播放的视频的流畅程度和视频质量，还可以通过控制设备83、控制设备84检测并显示通信终端60的实时等效SNR（信噪比，Signal to noise ratio）或者显示吞吐量曲线，通过实时等效SNR或者显示吞吐量曲线评价D2D传输过程中的每一段传输链路的通信质量受到将经过模拟信号阻挡91、模拟信号阻挡92和模拟信号阻挡93的影响大小。
在其他实施场景中，可以比对模拟信号阻挡91、模拟信号阻挡92和模拟信号阻挡93是模拟行人阻挡时控制设备85播放视频的流程程度和视频质量、时等效SNR以及显示吞吐量曲线与模拟信号阻挡91、模拟信号阻挡92和模拟信号阻挡93是金属网时制设备85播放视频的流程程度和视频质量、时等效SNR以及显示吞吐量曲线，得出不同模拟信号阻挡对D2D通信质量的干扰大小。
通过上述描述可知，本实施例使用基于微型电信计算架构平台的通信终端，在各通信终端之间添加模拟信号阻挡，通过比对添加模拟信号阻挡前后的视频播放质量、实时信噪比和吞吐量曲线中的至少一项检测模拟信号阻挡对D2D通信质量的影响，方法简单易行。
