201110369126.2、发明名称为"一种用于基站管理的***和基站管理方法", 2011年 11月 18 日提交中国专利局、 申请号为 201110369130.9、发明名称 为 "一种无线通讯***、 云虚拟基站和资源调度方法" , 以及 2011年 11 月 18 日提交中国专利局、 申请号为 201110369138.5、 发明名称为 "一种 无线通讯***、 云虚拟基站和资源调度方法" 的中国专利申请的中国专利 申请的优先权, 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及无线通讯领域, 尤其涉及用于基站管理的***和基站管理 方法、 无线通讯***、 云虚拟基站和资源调度方法。 背景技术
一方面:
公用移动通信基站是无线电台站的一种形式, 是指在一定的无线电覆 盖区中, 通过移动通信交换中心, 与移动电话终端之间进行信息传递的无 线电收发信电台。
传统的无线基站***具有以下特点: 每个基站连接若干固定数量的扇 区天线, 并覆盖小片区域, 每个基站只能处理本小区收发信号, 基站与其 覆盖的区域有严格的绑定关系; 基站之间的资源不能共享, 当一个基站的 业务量或者信令流量持续增长时可能会导致基站处理负荷过重而发生故 障; 基站***的资源利用率不高, 网络上有些基站业务负荷过轻, 有些业 务负荷过重, 不能有效的进行资源调配; 传统基站***只能通过 Scale up 的方式扩展能力, 能力的可扩展性受限, 如受成本、 关键芯片等限制; 传 统的基站并不区分虚拟基站与物理基站, 基站业务与基站设备的严格绑定 的。
当前的基站虚拟化方案主要的设计思路是将计算节点的资源虚拟化, 如, 将一个计算节点虚拟成一个或者多个计算资源, 从而部署一个或者多 个虚拟基站。 这种方式主要用于解决当一个计算节点的能力充裕的情况 下, 如何充分利用计算能力的场景。
如图 1所示, 为目前的虚拟基站的层次结构。 在该方案主要是在一个 计算节点上 (比如多核处理器) 安装一层管理程序 (Hypervisor ) , 其完 成计算节点虚拟化; 在该层之上安装多个客户操作*** (Guest OS ) , 基 站软件安装在 Guest OS之上, 不同的基站可以共享节点 (Node ) 的计算 能力。
该方案的不足之处在于当一个 Node的计算能力不足时***能力将成 为瓶颈, ***的计算能力不能弹性扩放, ***性能、 容量受一个 Node的 能力制约。
一方面:
RAN Sharing可以使得多个运营商共享无线网络的接入基础设施, 从而 达到多种目的: 节省运营商在基础设施方面的管理开销 ( Operating Expense, OPEX )和资金投入 ( Capital Expenditure, CAPEX ) ; 增加当前运营商的盈 利收入; 降低新兴运营商的市场门槛; 运营商的竟争力从网络基础设施 /部署 转向服务、 创新能力的竟争; 大大加速网络的部署; 构建绿色网络。
现有的 RAN Sharing架构主要包括两种: 1、 一个基站( Base Transceiver Station, BTS )设备的不同小区资源分配给不同的运营商, 不同的运营商可 以独立的调整小区参数,独立的进行网络优化,从而形成差异化的竟争优势; 2、一个基站设备的同一个小区资源可以同时被多个运营商共享,运营商不能 独立调整小区相关的参数。
上述两种方案共同特点在于有更多的运营商共享一个基础设施。 但是, 不同的基础设施单元(比如 BTS )之间独立 , 其资源不能相互共享, 当一个 BTS故障, 将会影响多个运营商的业务; 当一个 BTS上的一个运营商的业务 负荷变大后, 将占用更多的处理资源, 可能会挤压另外一个运营商的业务, 从而影响其他运营商的业务质量。 再一方面:
多制式(或称多模)基站(Base Transceiver Station, BTS ) ^^站*** 发展的一个主流方向, 可以有效的降低运营商的建网成本, 比如: 多模基站 多制式合一, 占用更小的空间, 可以安装在现有的基站机房中, 降低了资金 投入(Capital Expenditure, CAPEX ) 。 另夕卜, 多模基站共享传输设备、 主设 备,其能耗也大大降低,因此也降低了管理开销(Operating Expense, 0PEX )。
现有的多制式基站主要有两种的实现方案:
1、 以通用移动通信*** ( Universal Mobile Telecommunications System, UMTS ) 、 长期演进(Long Term Evolution, LTE )双制式为例, 设计上硬件 为独立的两套(主控单元、基带单元、传输单元),两套硬件分别提供 UMTS、 LTE业务,相互之间完全隔离,完全独立的两套***安装在一个 BTS设备中。
该方案的主要缺点: 支持其他制式非常困难: 由于硬件约束, 支持新的 制式需要新的一套硬件, 开发成本 4艮高; 难以支持两种以上的制式: 3 种制 式共存就需要三套硬件, 由于 BTS空间制约, 很可能没有足够的空间容纳 3 套硬件设备, 导致不能支持 3模。
2、 仍以 UMTS、 LTE双制式为例, 设计上硬件为公共的硬件平台 (主 控单元、 基带单元、 传输单元) , 软件为公共的软件平台, 不同制式的业务 可以同时运行在公共的软件平台上。
该方案相比方案 1有了很大的进步, 但是也有缺点: 在多个制式并发的 场景下, 不同制式业务抢占同一套硬件资源, 可能导致某一个制式的业务受 损; BTS硬件故障, 可能导致两种制式的业务均受损且不能恢复。
在介于方案一和方案二之间还有很多的过渡性方案 (比如: 主控硬件共 享、 基带硬件分离) , 也同样存在上述的问题。 发明内容 一方面,

云虚拟基站平台 50 ,用于将物理层的多个节点的计算资源和网络资源 虚拟为资源层的逻辑资源, 在资源调度层将所述资源层提供的逻辑资源调 度给不同的云虚拟基站。
即, 云虚拟基站平台可分为三层: 物理层、 资源层、 资源调度层。 物理层:物理层资源为海量 Node的计算资源和网络资源。每一个 Node 的计算资源可包含两部分, 一部分是通用计算资源(比如 Node上 CPU处 理能力, 内存容量, Cache容量等可以体现计算能力的资源) , 另一部分 是专用计算资源 (比如 Node上 DSP、 FPGA、 ASIC, SOC等专用芯片的 计算资源 ) ;
资源层: 资源层资源为承载在 Node上用来处理各种特定任务的资源, 如管理控制资源、 信令资源、 传输资源、 基带处理资源等。 资源层资源是 对物理层资源的进一步抽象, 即将物理层资源虚拟为逻辑资源后向上提供 服务。 资源调度层: 资源调度层将资源层提供的资源按照资源调度策略分配 到各个 cvBTS中。 cvBTS使用的资源可以来自于多个 Node, 此处不对具 体的资源调度算法做任何约束。
与图 2中的***拓朴结构向对应的, 在本实施例的分层架构中: 云虚拟基站平台的物理层资源由多个节点提供, 所述多个节点中的任 一个节点为计算机、 基站收发台或其他具有计算能力的设备;
云虚拟基站平台的资源调度层功能由节点管理设备提供, 所述节点管 理设备部署在所述多个节点中的任一个节点上, 或所述节点管理设备单独 部署在独立的服务器上。
云虚拟基站 (图中示例为 cvBTS 0、 cvBTS 1 cvBTS n ) 52, 所述云虚拟基站 52基于云虚拟基站平台 50调度的逻辑资源提供基站服 务。
云虚拟基站管理设备 54, 用于对多个所述云虚拟基站 52进行管理。 同理, 云虚拟基站管理设备部署在所述多个节点中的任一个节点上, 或所 述云虚拟基站管理设备与所述节点管理设备部署在一起, 或所述云虚拟基 站管理设备单独部署在独立的服务器上。图中未示云虚拟基站管理设备 54 与 cvBTS和云虚拟基站平台之间的联系, 具体联系可参考图 2中的 cvBTSMgr与 cvBTS的关系, 与云虚拟基站平台 50的关系可参考图 2中 的 cvBTSMgr与 NodeMgr和 Node的关系。
本实施例主要是为了说明云虚拟基站实现***中的分层结构。 通过上 述描述可以理解到, 本发明实施例中的云虚拟基站具有三方面的能力: 云虚拟基站接口, 云虚拟基站对外部业务网元体现的接口完全符合标 准协议 (比如: NBAP、 SI ) , 从外部业务网元来看, 其无法识别该基站 是云虚拟基站还是传统的基站。
逻辑资源, 云虚拟基站所使用的资源可以来自于云中任何的 Node, 云虚拟基站所使用的资源可以虚拟为 4大类: 管理控制资源、 信令资源、 传输资源和基带处理资源。 当然, 根据具体业务的需要, 也可增加或改变 对逻辑资源的分类, 此处不做赘述。
调度算法, 云虚拟基站中用到的资源调度算法、 L1/L2/L3处理算法等 可以参考无线通讯领域中的各种资源调度算法、 网络拓朴算法等等, 此处 不做赘述。
由上面的描述可以看出, 云虚拟基站与传统的虚拟基站的本质区别在 于云虚拟基站使用的资源可以来自于云中任意的 Node, 云虚拟基站可以 根据业务负荷情况动态申请、 释放资源, 从而做到资源的弹性扩放。 而传 统的虚拟基站只能使用一个 Node中的资源, 无法做到资源的弹性扩放。
相应于上述***架构, 本发明实施例还提供了一种基站管理方法, 用 于如上所述的基站***中,如图 6所示,该方法包括资源虚拟和注册过程。 本例中以两个节点为例进行说明。
401、 节点启动, 并在启动后将自身的计算资源和网络资源虚拟为逻 辑资源。 本例中示意了两个节点 Node O和 Node N的情况, 当然, 两个节 点之间的启动顺序可能是同时进行, 也可能有先有后。
402、 节点将所述逻辑资源的信息注册到节点管理设备。
403、 节点管理设备将注册的逻辑资源的信息形成资源池, 所述资源 池中记录有所述逻辑资源的功能描述和提供所述逻辑资源的地址信息。

605、 云虚拟基站管理设备通知该云虚拟基站该退出的节点提供的资 源不可用。

702、 云虚拟基站管理设备通知创建该云虚拟基站的节点删除该云虚 拟基站。
703、 该创建该云虚拟基站的节点在本地释放该云虚拟基站的业务资 源。
704、 该节点通知所述云虚拟基站管理设备释放该云虚拟基站的逻辑 资源。
705、 云虚拟基站管理设备通知所述节点管理设备释放资源池中该云 虚拟基站的逻辑资源。

902、 云虚拟基站向云虚拟基站管理设备申请释放资源;

综上所述可以理解, 在本发明实施例中提出了一种虚拟基站构建方 案, 能够实现在海量 Node之间共享计算能力, ***整体的计算能力可以 根据业务量进行动态弹性扩放和收缩, 很好的应对临时大业务量沖击的场 景, 而在业务较少的时候减少***功耗。 一方面,
本发明实施例提出了一种基于云虚拟基站平台和云虚拟基站 ( Cloud based virtual BTS , cvBTS ) 的 RAN Sharing方案, 能够实现多个运营商共 享海量基站物理资源 (如节点)之间的计算能力, ***整体的计算能力可 以根据各个云虚拟基站的业务量进行动态弹性扩放, 很好的应对临时大业 务量沖击的场景。
如图 12所示, 为本发明实施例中的无线通讯***的一个具体组成示 意图。 该设备 1包括: 云虚拟基站平台 10, 用于将物理层的节点的基站物 理资源虚拟为资源层的逻辑资源, 在资源调度层将所述资源层提供的逻辑 资源调度给云虚拟基站, 其中, 所述基站物理资源包括节点计算资源和节 点网络资源; 云虚拟基站 12, 用于基于云虚拟基站平台 10调度的逻辑资 源向一个或多个运营商提供基站服务; 云虚拟基站管理设备 14, 用于对所 述云虚拟基站进行管理。
为了标明云虚拟基站提供服务的运营商, 云虚拟基站可包括运营商标 识, 所述云虚拟基站根据所述运营商标识向运营商提供基站服务。 即, 云 虚拟基站增加属性: 云虚拟基站运营商标识: OperatorId。 一个典型的增 加云虚拟基站操作示意如下: ADD cvBTS: cvBTSId, RatType, Operatorldo 当然该操作为一个示意, 还可以有其他的形式, 此处不做赘述。
如图 13a所示, 当多个云虚拟基站向多个运营商提供基站服务时, 同 一个云虚拟基站可以仅向唯一的运营商提供基站服务。 在本实施例中, 运 营商为运营商 A ( OpA ) 和运营商 B ( OpB ) , 每个云虚拟基站 (cvBTS 中的小区 fl和 f2均提供给同一个运营商) 。 本例中, 仅举例了两个运营 商的情况, 当然还可以有更多的运营商, 此处不做赘述。 图中未示 cvBTSMgr。
同时, 在本例中, 云虚拟基站平台根据功能划分为三层, 物理层中包 括节点(Node )计算资源和 Node网络资源; 资源层中包括管理控制资源、 信令资源、 基带资源和传输资源; 资源调度层则对资源层中的资源进行分 配和调度。
其中, Node计算资源可包括通用计算资源和专用计算资源, 则资源 层将物理层的资源进行抽象, 资源的抽象需要考虑专用资源, 比如某些专 用计算资源仅仅用来处理通用移动通信*** ( Universal Mobile
Telecommunications System, UMTS ) 的基带算法, 而另外的专用计算资 源用来处理长期演进(Long Term Evolution, LTE ) 的基带算法。
本实施例中, 所述逻辑资源包括管理控制资源、 信令资源、 基带资源 和传输资源, 如, 将通用计算资源抽象为管理控制资源和信令资源, 网络 资源抽象为传输资源; 最终资源层将抽象出一系列的资源能力: UMTS管 理控制资源能力、 UMTS信令资源能力、 UMTS基带资源能力, LTE管理 控制资源能力、 LTE信令资源能力、 LTE基带资源能力, 时分同步(Time Division Synchronous, TDS ) CDMA管理控制资源能力、 TDSCDM信令 资源能力、 TDSCDM基带资源能力, 以及传输资源能力。
本实施例中云虚拟基站平台的物理层和资源层的功能由***中的节 点提供, 所述节点为计算机、 基站收发台或其他具有计算能力的设备; 所 述云虚拟基站平台的资源调度层的功能由节点管理设备提供, 所述节点管 理设备部署在所述节点上或部署在独立的服务器上。
云虚拟基站可根据其运营商的业务需要向所述云虚拟基站平台的资 源调度层请求相应的资源; 云虚拟基站平台则根据云虚拟基站的请求通过 所述资源调度层的调度将所述资源层提供的逻辑资源调度给所述云虚拟 基站使用。 由于逻辑资源实际上是由节点的基带物理资源抽象出来的, 因 而上述的调度最终可以实现将***中的节点提供的基带物理资源调度给 云虚拟基站使用。
同时, 当向云虚拟基站提供资源的节点故障时, 云虚拟基站平台可在 资源调度层根据资源调度算法将所述资源层提供的其他节点的逻辑资源 分配给云虚拟基站。
这样, 在本实施例中, 可以控制一个云虚拟基站在同一时间仅向一个 运营商提供服务, 使得向不同运营商提供服务的云虚拟基站不同, 可减少 运营商之间的耦合; 另一方面, 即使一个云虚拟基站同时向多个运营商提 供服务, 但是其可通过云虚拟基站平台进行资源调度, 也可以减少使用同 一云虚拟基站提供服务时的运营商之间由于业务变化造成的影响, 如, 当 向某个云虚拟基站提供资源的节点等物理资源出现故障时, 通过云虚拟基 站平台的调用, 可以及时满足云虚拟基站的需求, 从而使云虚拟基站的业 务可以快速恢复或实现业务无损, 提高了设备运行的业务安全; 同时, 当 云虚拟基站的业务突然增加时, 该云虚拟基站可以向云虚拟基站平台请求 分配新的资源, 增加云虚拟基站的业务处理能力, 提高了基站资源的共享 效率。
如图 13b所示, 为本发明的另一具体实施例, 在本例中多个云虚拟基 站向多个运营商提供基站服务, 同一个云虚拟基站向多个运营商提供基站 服务。 其中每一个云虚拟基站可以不属于任何一个特定的运营商, 比如, 可属于第三方的云虚拟基站提供方。 每一个云虚拟基站上小区可以被多个 运营商共享, 而每一个云虚拟基站可以使用来自***中任何节点的资源。 同样, 在本实施例中, 仅举例了两个运营商的情况, 当然还可以有更多的 运营商, 此处不做赘述。
同样的, 在本例中, 云虚拟基站平台根据功能划分为三层, 物理层中 包括 Node计算资源和 Node网络资源; 资源层中包括管理控制资源、信令 资源、 基带资源和传输资源; 资源调度层则对资源层中的资源进行分配和 调度。 其中, Node计算资源可包括通用计算资源和专用计算资源, 则资 源层将物理层的资源进行抽象, 资源的抽象需要考虑专用资源, 比如某些 专用计算资源仅仅用来处理 UMTS的基带算法,而另外的专用计算资源用 来处理 LTE的基带算法。 本实施例中, 将通用计算资源抽象为管理控制资源和信令资源, 网络 资源抽象为传输资源; 最终资源层将抽象出一系列的资源能力, 具体与图
13中的示例一致, 此处不做赘述。
同样的, 在本实施例中, 当向某个云虚拟基站提供资源的节点等物理 资源出现故障时, 通过云虚拟基站平台的调用, 可以及时满足云虚拟基站 的需求, 从而使云虚拟基站的业务可以快速恢复或实现业务无损, 提高了 设备运行的业务安全; 同时, 当某一个云虚拟基站上的某一个运营商的业 务持续增长时, 云虚拟基站可以根据业务负荷情况向云虚拟基站平台申请 更多的资源, 从而避免由于某一个运营商的业务持续增加而挤压另外一个 运营商的业务的情况(相对的, 则是在现有的方案中, 当多运营商共享一 个基站的资源时, 由于一个基站的资源是相对受限的, 很容易导致运营商 之间相互挤压业务) , 一定程度上也降低了运营商之间基站资源的耦合。
如图 14a所示, 为本发明实施例中的云虚拟基站的组成示意图, 该云 虚拟基站 12包括: 资源获取单元 120, 用于根据业务需要向云虚拟基站平 台的资源调度层请求相应的逻辑资源, 以使所述云虚拟基站平台根据所述 云虚拟基站的请求将逻辑资源通过资源调度层调度给所述云虚拟基站使 用, 其中, 所述逻辑资源是所述云虚拟基站平台将物理层的节点的基站物 理资源虚拟为资源层的逻辑资源, 并在资源调度层进行调度的; 服务提供 单元 122, 用于基于所述云虚拟基站平台调度的逻辑资源向一个或多个运 营商提供基站服务。
其中, 服务提供单元 122可基于所述云虚拟基站平台调度的逻辑资源 向唯一的运营商提供基站服务或向多个运营商提供基站服务。 如, 可参考 图 13a和 13b中的示例。
当***中节点变化或业务变化时, 该资源获取单元 120还可以根据该 变化向云虚拟基站平台请求进行资源调度, 具体可参考后述的资源调度方 法和基站管理方法中的描述。
如图 14b , 为本发明实施例中虚拟基站***的网络拓朴示意图。 该系 统包括如下五大部分。
一个或多个节点(Node ) 20, 图 14b中示例为 5个节点, 分别为节点 0、 节点 1、 节点 2、 节点 3、 节点 4, 用于提供基站的计算资源和网络资 源, 并将该计算资源和网络资源虚拟为逻辑资源。
该逻辑资源包括管理控制资源、 信令资源、 基带资源和传输资源, 则 可以将计算资源和网络资源对应的虚拟为管理控制资源、 信令资源、 基带 资源和传输资源。 当然, 根据具体业务的需要, 也可增加或改变对逻辑资 源的分类, 此处不做赘述。 Node可以是同构的也可以是异构的, 比如一 个 PC机可能是一个 Node,—个基站收发台(Base Transceiver Station, BTS) 可能是一个 Node; 本发明实施例中的 Node可以是任何具有计算能力的设 备, 即, 上述 5个节点中的任一个节点为计算机、 基站收发台或其他具有 计算能力的设备。
交换设备 22, 用于进行所述节点之间的数据交换。 在本发明的具体实 施例中, 交换设备(Switch ) 可以是任何具有数据交换能力的设备, *** 中可以有多个 Switch , 多个 Switch可以组网形成复杂的拓朴。

节点管理设备可以部署在所述多个节点中的任一个节点上, 或单独部 署在独立的服务器上。 若节点管理设备部署在某一个节点上, 则节点管理 设备和各节点的信息交互可以通过上述交换设备实现; 若节点管理设备部 署在单独的服务器上, 则节点管理设备也可以和交换设备连接, 节点管理 设备和各节点的信息交互可以通过上述交换设备实现, 当然节点管理设备 也可以分别与部分或全部的节点连接, 实现直接或间接的信息交互。
云虚拟基站管理设备(cvBTSMgr ) 26, 用于根据节点管理设备提供 的资源池信息,管理控制所述云虚拟基站( Cloud based virtual BTS , cvBTS ) 的资源。
云虚拟基站管理设备可部署在所述多个节点中的任一个节点上, 或与 所述节点管理设备部署在一起, 或单独部署在独立的服务器上。
相似的, 若云虚拟基站管理设备部署在某一个节点上, 则云虚拟基站 管理设备和各节点的信息交互可以通过上述交换设备实现; 若云虚拟基站 管理设备部署在单独的服务器上, 则云虚拟基站管理设备也可以和交换设 备连接, 云虚拟基站管理设备和各节点的信息交互可以通过上述交换设备 实现, 当然云虚拟基站管理设备也可以分别与部分或全部的节点连接, 实 现直接或间接的信息交互。
一个或多个云虚拟基站 (cvBTS ) 28, 用于根据所述云虚拟基站管理 设备的管理和所述节点管理设备的调度获得所述逻辑资源, 并基于所述逻 辑资源提供基站服务。 图 3b中示例为 3个, 分别为 cvBTS 0、 cvBTS 1和 cvBTS 2。 每个 cvBTS的资源由该 cvBTS所关联的圈内的节点提供, 如本 例中所示的, cvBTS O的资源由节点 0和节点 1所提供, cvBTS O由 cvBTSMgr 4进行管理, 节点 0和节点 1则接受 NodeMgr 3的管理, 其余 解释类同。
当然, 本实施例中的各个设备数量不受图 14b中示例的局限, 还可以 有多种可能, 在此不赘述。
云虚拟基站可以跨 Node部署, 一个云虚拟基站使用的逻辑资源可以 来自于一个或多个 Node; —个 Node的逻辑资源也可以分配给一个或多个 云虚拟基站使用。 一般来说, 云虚拟基站部署在节点上, 云虚拟基站的资 源管理模块可以部署在提供管理控制资源的节点上, 而云虚拟基站的逻辑 资源则可能来自各个节点, 其中云虚拟基站的资源管理模块用于实现对该 云虚拟基站的逻辑资源进行管理控制。
如图 14b所示, 云虚拟基站 cvBTSO使用了 Node0、 Nodel的资源, cvBTSl使用了 Node3、 Node4的资源, cvBTS2使用 Nodel、 Node2、 Node3 的资源。
相应于上述的***实施例, 本发明实施例还提供了一种资源调度方 法, 用于上述***中, 如图 15所示, 该方法包括:
401、 云虚拟基站根据业务需要向云虚拟基站平台的资源调度层请求 相应的逻辑资源, 以使所述云虚拟基站平台根据所述云虚拟基站的请求将 逻辑资源通过资源调度层调度给所述云虚拟基站使用, 所述逻辑资源是所 述云虚拟基站平台将物理层的节点的基站物理资源虚拟为资源层的逻辑 资源, 并在资源调度层进行调度的。

再一方面,

基于本方面所提出的实施例, 也可以实现多个运营商共享海量基站物 理资源 (如节点)之间的计算能力。 ***整体的计算能力可以根据各个云 虚拟基站的业务量进行动态弹性扩放, 很好的应对临时大业务量沖击的场 景。 反过来, 前一方面所提出的实施例, 也可以全部或者部分实现本方面 所提出的实施例的功能, 即, 基于云虚拟基站平台和云虚拟基站 ( Cloud based virtual BTS , cvBTS ) 的多制式基站实现方案, 能够实现多种制式的 基站在海量基站物理资源 (如, Node )之间共享计算能力, ***整体的计 算能力可以根据业务量进行动态弹性扩放, 很好的应对临时大业务量沖击 的场景。
考虑到本方面所提出的实施例, 也可以实现前一方面所描述的多个运 营商共享海量基站物理资源 (如节点)之间的计算能力的功能。 因此, 本 实施例中的附图, 如有和前一方面所提出的实施例中的附图, 图的全部或 者部分类似,也可以理解为这些附图或者附图中的装置部件 /方法步骤可以 执行相同的功能。
如图 22a所示, 为本发明实施例中的无线通讯***的一个具体组成示 意图。 该*** 1包括: 云虚拟基站平台 10, 用于将物理层的节点的基站物 理资源虚拟为资源层的逻辑资源, 在资源调度层将所述资源层提供的逻辑 资源调度给云虚拟基站, 其中, 所述基站物理资源包括节点计算资源和节 点网络资源, 所述云虚拟基站是具有不同制式的云虚拟基站, 其中, 所述 逻辑资源包括管理控制资源、 信令资源、 基带资源和传输资源; 云虚拟基 站 12, 用于基于所述云虚拟基站平台 10调度的逻辑资源提供预定制式的 基站服务; 云虚拟基站管理设备 14, 用于对所述云虚拟基站进行管理。
需要说明的是, 图 22a中的各设备之间的连线仅仅是一示例, 在需要 时, ***中的各设备还可有更多的联系, 如, 云虚拟基站管理设备与云虚 拟基站平台之间也可以有直接的联系等。
同时, 在一个***中的云虚拟基站的数量可以根据业务需要和资源限 制来确定, 同一个制式下可以有多个云虚拟基站。
为了区别具有不同制式的云虚拟基站, 云虚拟基站可包括云虚拟基站 标识属性和云虚拟基站制式标识属性, 所述云虚拟基站标识属性用于标识 不同的云虚拟基站, 所述云虚拟基站制式标识属性用于标识云虚拟基站的 制式; 这样***和网络中的其他设备就可以区别不同的云虚拟基站和其制 式。 如, 云虚拟基站可包括: 属性一: 云虚拟基站实例标识: cvBTSId; 属性二: 云虚拟基站制式标识: RatType。 则一个典型的增加云虚拟基站 操作示意如下: ADD cvBTS: cvBTSId, RatType。 当然该操作为一个示 意, 还可以有其他的形式, 此处不做赘述。
其中, 具有不同制式的云虚拟基站包括下面的一种或多种: UMTS制 式的云虚拟基站、 LTE制式的云虚拟基站和时分同步 ( Time Division Synchronous , TDS ) CDMA制式的云虚拟基站。
如图 22b所示, 云虚拟基站平台根据功能划分为三层, 物理层中包括 Node计算资源和 Node网络资源;资源层中包括管理控制资源、信令资源、 基带资源和传输资源; 资源调度层则对资源层中的资源进行分配和调度。
其中, Node计算资源可包括通用计算资源和专用计算资源, 则资源 层将物理层的资源虚拟为逻辑资源, 资源的虚拟需要考虑专用资源, 比如 某些专用计算资源仅仅用来处理 UMTS的基带算法,而另外的专用计算资 源用来处理 LTE的基带算法。
将计算资源和网络资源虚拟为逻辑资源, 即资源层将虚拟出一系列的 资源能力: UMTS管理控制资源能力、 UMTS信令资源能力、 UMTS基带 资源能力, LTE管理控制资源能力、 LTE信令资源能力、 LTE基带资源能 力, TDS管理控制资源能力、 TDS信令资源能力、 TDS基带资源能力, 以及传输资源能力。
本实施例中基站物理资源由***中的节点提供。 云虚拟基站可根据其 业务需要向所述云虚拟基站平台的资源调度层请求相应的资源; 云虚拟基 站平台则根据所述云虚拟基站的请求通过所述资源调度层的调度将所述 资源层提供的逻辑资源调度给所述云虚拟基站使用。
当向所述云虚拟基站提供资源的节点故障时, 云虚拟基站平台还用于 在所述资源调度层根据资源调度算法将***中其他节点提供的基站物理 资源虚拟为逻辑资源后分配给所述云虚拟基站。
这样, 在本实施例中, 通过云虚拟基站平台将基站物理资源整合后提 供给具有不同制式的云虚拟基站, 当基站物理资源故障或云虚拟基站资源 需求增加时, 通过云虚拟基站平台可以有效的实现资源的调配, 提高资源 共享的安全性和有效性。
如, 当向某个云虚拟基站提供资源的节点等物理资源出现故障时, 通 过云虚拟基站平台的调用, 可以及时满足云虚拟基站的需求, 从而使云虚 拟基站的业务可以快速恢复或实现业务无损, 提高了***运行的业务安 全; 同时, 当云虚拟基站的业务突然增加时, 该云虚拟基站可以向云虚拟 基站平台请求分配新的资源, 增加云虚拟基站的业务处理能力, 提高了基 站资源的共享效率。
如图 23所示, 则为本发明实施例中的云虚拟基站的组成示意图。 本 例中的云虚拟基站是具有预定制式的云虚拟基站, 其包括: 资源获取单元 120, 用于根据业务需要向云虚拟基站平台的资源调度层请求相应的逻辑 资源, 以使所述云虚拟基站平台根据所述云虚拟基站的请求将逻辑资源通 过资源调度层调度给所述云虚拟基站使用, 其中, 所述逻辑资源是所述云 虚拟基站平台将物理层的节点的基站物理资源虚拟为资源层的逻辑资源, 并在资源调度层进行调度的; 服务提供单元 122, 用于基于所述云虚拟基 站平台调度的逻辑资源提供预定制式的基站服务。
如图 24所示, 为本发明实施例中的虚拟基站***的网络拓朴示意图。 该***包括如下五大部分。
一个或多个节点(Node ) 20, 图 3中示例为 5个节点, 分别为节点 0、 节点 1、 节点 2、 节点 3、 节点 4, 用于提供基站的计算资源和网络资源, 并将该计算资源和网络资源虚拟为逻辑资源。
该逻辑资源包括管理控制资源、 信令资源、 基带资源和传输资源, 则 可以将计算资源和网络资源对应的虚拟为管理控制资源、 信令资源、 基带 资源和传输资源。 当然, 根据具体业务的需要, 也可增加或改变对逻辑资 源的分类, 此处不做赘述。 Node可以是同构的也可以是异构的, 比如一 个 PC机可能是一个 Node,—个基站收发台(Base Transceiver Station, BTS) 可能是一个 Node; 本发明实施例中的 Node可以是任何具有计算能力的设 备, 即, 上述 5个节点中的任一个节点为计算机、 基站收发台或其他具有 计算能力的设备。
交换设备 22, 用于进行所述节点之间的数据交换。 在本发明的具体实 施例中, 交换设备(Switch ) 可以是任何具有数据交换能力的设备, *** 中可以有多个 Switch , 多个 Switch可以组网形成复杂的拓朴。

一个或多个云虚拟基站 (cvBTS ) 28, 用于根据所述云虚拟基站管理 设备的管理和所述节点管理设备的调度获得所述逻辑资源, 并基于所述逻 辑资源提供基站服务。 图 3中示例为 3个, 分别为 cvBTS 0、 cvBTS 1和 cvBTS 2。 每个 cvBTS的资源由该 cvBTS所关联的圈内的节点提供, 如本 例中所示的, cvBTS O的资源由节点 0和节点 1所提供, cvBTS O由 cvBTSMgr 4进行管理, 节点 0和节点 1则接受 NodeMgr 3的管理, 其余 解释类同。
当然, 本实施例中的各个设备数量不受图 3中示例的局限, 还可以有 多种可能, 在此不赘述。
云虚拟基站可以跨 Node部署, 一个云虚拟基站使用的逻辑资源可以 来自于一个或多个 Node; —个 Node的逻辑资源也可以分配给一个或多个 云虚拟基站使用。 一般来说, 云虚拟基站部署在节点上, 云虚拟基站的资 源管理模块可以部署在提供管理控制资源的节点上, 而云虚拟基站的逻辑 资源则可能来自各个节点, 其中云虚拟基站的资源管理模块用于实现对该 云虚拟基站的逻辑资源进行管理控制。
如图 24所示, 云虚拟基站 cvBTSO使用了 Node0、 Nodel的资源, cvBTSl使用了 Node3、 Node4的资源, cvBTS2使用 Nodel、 Node2、 Node3 的资源。
