Description

一种多用户多入多出的实现方法和系统
本申请要求2016年04月12日提交的申请号为：201610224205.7、发明名称为“一种多用户多入多出的实现方法和系统”的中国专利申请的优先权，其全部内容合并在此。
技术领域
本发明实施例涉及通信技术领域，尤其涉及一种多用户多入多出的实现方法和系统。
背景技术
MU-MIMO(Multi-User Multiple-Input Multiple-Output，多用户多入多出)是一种让你的路由器同时与多个设备沟通的技术，它是802.11ac标准第二阶段的里程碑，这种进步甚至比802.11b/g到802.11n，再到802.11ac来得还要大，因为版本号的进化只是提升了理论速率，MU-MIMO才是真正改善了网络资源利用率。
MU-MIMO的主要目的是提升WiFi网络的效率。假设把传统的802.11ac路由器信号想象成是一个“圆圈”，这个圆圈就是信号的覆盖范围，天线在圆心，呈360度向外发射信号。在“圆圈”内的设备，路由器会依次与它们进行通讯，每次都是一个对一个，多了不行。
MU-MIMO包括上行MU-MIMO和下行MU-MIMO，其中上行MU-MIMO不同用户使用相同的时频资源进行上行发送，从接收端来 看，这些数据流可以看作来自一个用户终端的不同天线，从而构成了一个虚拟的MIMO系统；下行MU-MIMO将多个数据流传输给不同的用户终端，多个用户终端以及eNB构成下行MU-MIMO系统，下行MU-MIMO可以在接收端通过消除/零陷的方法，分离传输给不同用户的数据流，还可以通过在发送端采用波束赋形的方法，提前分离不同用户的数据流，从而简化接收端的操作。
MU-MIMO可大大增强用户的接入数，最大支持8根天线。但是，通常在实际AP的开发中，一般在5G频段最多支持4根天线，原因是：大部分用户需要的天线数量小于等于4根，只有部分用户需要超过4根天线。所以超过4根天线的AP没有很大的市场。这导致了那些需要一个AP支持超过4根天线的用户无法找到适用的产品。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明实施例中多用户多入多出的实现方法的流程示意图；
图2为本发明实施例中多用户多入多出的实现系统的架构示意图。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
目前大部分用户需要的天线数量小于等于4根，因此需要一个AP支持超过4根天线的用户很难找到适用的产品。
本发明提出了一种通过堆叠两个AP实现MU-MIMO，可使得用户可以用两个支持MU-MIMO 4根天线的AP组合成一台MU-MIMO 8根天线的AP。
图1为本发明实施例中多用户多入多出的实现方法的流程示意图，如图1所示，包括：
步骤S11，预先连接两个支持MU-MIMO的接入点形成堆叠虚拟接入点。
在本步骤中，将两个支持MU-MIMO的拥有4根天线的接入点(AP，Access Point)用网线直接相连，两个支持MU-MIMO的接入点之间的通信采用二层通信，该二层通信使用的私有协议实现在本发明实施例中并不做限制。
步骤S12，在所述堆叠虚拟接入点中设置主接入点和备用接入点。
在本步骤中，两个接入点连接完成后，设置一接入点为主接入点，另一接入点为备用接入点。
由于数据量很大，100M的接口无法满足要求，因此本发明实施例中的接入点应能够支持两个GE接口，例如eth0和eth1。GE是Gigabit Ethernet的缩写，即1000M传输速率的以太网。GE接口，指的是Gigabit  Ethernet千兆以太网接口，带有GE标记的接口，说明是1000M以太网网络接口。
在本发明的具体实施例中，将主接入点的eth0口外连交换机，作为整个堆叠虚拟接入点的上联口，主接入点的eth1口连接备用接入点的eth0口，备用接入点的eth1不做使用。
步骤S13，在主接入点上进行接入点的配置，并将主接入点的配置同步给备用接入点。
在本步骤中，配置保持在主接入点上，主接入点通过私有协议将主接入点的配置同步给备用接入点，使得备用接入点上所有的配置和主接入点一致。
步骤S14，主接入点进行所述堆叠虚拟接入点的所有天线的调度。
在本步骤中，所有天线的调度都统一由主接入点来决定。备用接入点把无线交互的信息透传给主接入点。具体的，当使用备用接入点的天线进行无线交互时，备用接入点将无线交互的信息上报给主接入点，主接入点转发给外连交换机进行处理。
步骤S15，如果主接入点出现故障，将备用接入点作为所述堆叠虚拟接入点的新主接入点。
在本步骤中，如果主接入点出现故障，将备用接入点作为新主接入点，原主接入点作为备用接入点。
在本发明实施例中，由于MU-MIMO规定每根天线都独立工作，连接不同的站点(STA)，所以这样相连使用没有技术问题，也就是说，堆叠虚拟接入点相当于一台至少拥有8根天线的接入点。
此外，由于现在是至少两个接入点，这样主接入点的4根天线和备用接入点的4根天线的空间距离较远，所以堆叠方式还会提高无线MIMO的性能。
需要注意的是，两个接入点堆叠在MU-MIMO中实现，MU-MIMO可以让主接入点的天线连一个用户，备用接入点的天线连另外一个用户，所以堆叠接入点实现MU-MIMO很容易做到。而如果是的单用户MIMO(SU-MIMO)中，由于所有天线都必须连一个用户，在当前技术上时很难做到的，但未来也有可能突破，在此并不做限制。
图2为本发明实施例中多用户多入多出的实现系统的架构示意图。如图2所示，该多用户多入多出MU-MIMO的实现系统中包括：两个支持MU-MIMO的接入点，所述两个支持MU-MIMO的接入点相互连接形成堆叠虚拟接入点，并在所述堆叠虚拟接入点中设置主接入点和备用接入点；其中，
所述主接入点，用于进行主接入点的配置，并将主接入点的配置同步给备用接入点；进行所述堆叠虚拟接入点的所有天线的调度；
所述备用接入点，用于根据主接入点的配置进行备用接入点的配置；通过主接入点对本接入点的所有天线进行调度。
具体地，
所述连接两个支持MU-MIMO的接入点形成堆叠虚拟接入点，具体为：将两个支持MU-MIMO的拥有4根天线的接入点用网线相连，每个接入点分别支持两个GE接口；所述两个支持MU-MIMO的接入点之间的通信采用二层通信。
在所述堆叠虚拟接入点中设置主接入点和备用接入点，具体为：两个接入点连接完成后，设置一个接入点为主接入点，另一个接入点为备用接入点；所述主接入点的一个GE接口外连交换机，作为所述堆叠虚拟接入点的上联口；所述主接入点的另一个GE接口和所述备用接入点的一个GE接口相连。
所述主接入点进行所述堆叠虚拟接入点的所有天线的调度，具体为： 如果使用所述主接入点的天线进行无线交互，则所述主接入点进行本接入点上天线的调度；如果使用所述备用接入点的天线和外连交换机进行交互，则所述备用接入点将无线交互的信息上报给所述主接入点，通过所述主接入点进行无线交互。
所述备用接入点，还用于如果所述主接入点出现故障，将本接入点作为所述堆叠虚拟接入点的新主接入点。
现有方案中，如果直接采用两个接入点，意味着这两个接入点必须工作在不同的独立无线信道，意味着多消耗了无线频谱资源。如果工作在同一信道，由于互相之间将出现同频干扰，将无法很好的正常工作，多消耗了无线资源，且导致吞吐量大幅度下降。
在本发明实施例中，采用两个接入点堆叠，组成一个的堆叠虚拟接入点，则可以充分发挥MU-MIMO最大支持8根天线的优势，使得两个接入点工作在同一个无线信道，意味着在没有多消耗无线频谱资源的前提下，实现了两个接入点的无线吞吐量。
以上所描述的装置实施例仅仅是示意性的，其中所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部模块来实现本实施例方案的目的。本领域普通技术人员在不付出创造性的劳动的情况下，即可以理解并实施。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到各实施方式可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件。基于这样的理解，上述技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品可 以存储在计算机可读存储介质中，如ROM/RAM、磁碟、光盘等，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行各个实施例或者实施例的某些部分所述的方法。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
