下面结合优选实施例和实施方式对本发明进行详细说明。
通过了本发明优选实施例，当云会议中有过多终端接入的时候，可以无缝地把呼叫资源和媒体资源分配到其他空闲资源的服务器上，解决了大量用户并发接入的应用场景
本优选实施例采用的技术方法包括以下步骤：
步骤1.当呼叫媒体资源调度器上电的时候，就向云服务器上电请求呼叫媒体资源上报，云服务器根据云服务器的CPU内核核数、内存等等资源分配了呼叫资源单元和媒体资源单元，并且上报给呼叫媒体资源调度器；
步骤2.当云服务器检测到有会议电视终端接入的时候，就向呼叫媒体资源调度器获取空闲的呼叫资源接入节点，否则就定时间向呼叫媒体调度器请求空闲资源上报；
步骤3.呼叫媒体资源调度器收到呼叫资源接入节点请求消息之后，先根据区号来分配空闲呼叫资源单元，如果区号对应的资源单元已经用满了，则从区域中分配一个空闲的呼叫资源单元，如果区域中无空闲的呼叫资源单元了，则从其他区域中分配接入，如果所有区域的资源都已经用完了，则直接拒绝呼叫接入，否则呼叫媒体资源调度器就把允许接入的呼叫资源的地址告诉终端；
步骤4.终端通过C步骤中分配的呼叫资源接入节点向叫媒体资源调度器获取空闲的媒体资源接入节点；
步骤5.呼叫媒体资源调度器收到媒体节点请求的消息之后，先根据接入媒体能力来选择对应的空闲媒体资源单元，如果找到，呼叫媒体资源调度器把媒体节点的地址告诉终端，否则就直接拒绝接入；
通过上述实施例，在云会议中资源过载的时候，可以均衡分配呼叫资源和媒体资源，使 会议资源得到最优使用，保证用户的大容量并发正常接入。
图3是根据相关技术中普通两点会议的示意图，如图3所示，其中，A和B都是普通终端，因为只是简单点对点的会议，不存在资源用完之后还有终端接入的情况，所以不需要实现呼叫媒体资源负载均衡
图4是根据相关技术中普通多点会议的示意图，如图4所示，其中，A为内置MCU终端或者为MCU，其它都为普通终端，假如普通终端大容量并发接入A，A会存在呼叫资源或者媒体资源不足的情况，造成了无法并发大容量接入普通终端，通过新增内置MCU终端或者MCU的级联方式也无法全面实现业务的可伸缩性，这样会影响其他终端并发大容量接入。
图5是根据优选实施例中云会议的示意图，如图5所示，是云会议的示意图。其中A为资源调度服务器，B1和B2均为1区云服务器，C1和C2均为2区云服务器，D1、E1、F1、G1、H1和L1均为1区的普通终端，D2、E2、F2、G2、H2和L2均为2区的普通终端，当1区的普通终端接入到云会议的时候，A根据路由规则配置找1区的云服务器来接入，当1区的云服务器的呼叫和媒体资源用完之后，可以找2区的云服务器接入，同理，当2区的普通终端接入云会议的时候，A根据路由规则配置找2区的云服务器来接入，当2区的云服务器的呼叫和媒体资源用完之后，可以找1区的云服务器接入。
图6是根据优选实施例中云会议的呼叫媒体资源负载均衡的流程图，如图6所示，呼叫媒体调度器发消息给每个区域的云服务器请求资源上报，每个区域的云服务器根据CPU核数、内存等资源分配了呼叫资源节点和媒体资源节点，并且上报给呼叫媒体调度器，每个区域中的每个云服务器定期检测是否有会议电视终端接入，如没有会议电视终端接入，则定时间循环上报该云服务器的空闲的呼叫资源节点和媒体资源节点，否则，云服务器则向呼叫媒体调度器请求呼叫接入资源节点，呼叫媒体调度器根据云服务器所属的区域的路由配置规则分配了空闲的呼叫接入资源节点，如果该区域没有空闲的呼叫接入资源节点，则从相邻的区域中继续分配，并且通过云服务器返回给终端，该终端通过该呼叫接入资源节点接入，会议电视终端再通过该呼叫接入资源节点向呼叫媒体调度器请求媒体节点，呼叫媒体调度器根据媒体资源分配规则分配了媒体资源节点，也就是先从该呼叫接入资源节点所在的区域中分配了媒体节点，如果该区域中没有空闲的媒体资源节点，则从相邻的区域中分配了媒体资源节点，并且通过该呼叫接入资源节点返回，会议电视终端通过该媒体资源节点传送码流，保证了云会议的正常会议。
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根据上述实施例的方法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，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的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，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。

可选地，在本实施例中，上述存储介质可以包括但不限于：U盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、移动硬盘、磁碟或者光盘等各种可以存储程序代码的介质。
可选地，在本实施例中，处理器根据存储介质中已存储的程序代码执行上述实施例的方法。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
