Description

一种综合接入系统、配置方法和基带处理单元 技术领域
本申请实施例涉及通信领域，尤其涉及一种综合接入系统、配置方法和基带处理单元。
背景技术
无线点系统(Lampsite)是一种室内覆盖解决方案，LampSite主要致力于移动宽带数据的室内覆盖，通过室内覆盖的数字化，大幅度降低室内覆盖建设和维护成本，促进移动宽带体验的提升。
随着移动通信市场的迅猛发展，用户越来越希望能随时随地接入高质量通信网络。为此，移动通信服务商开始在室外、建筑物内部及地下等电波难以覆盖的盲区设置直放站，以最大限度地满足用户对于通话服务的需求。基于LampSite实现的综合接入系统是专用的支持多制式多频段的分布式系统架构，如图1所示，目前的综合接入系统中还包括多种产品功能模块，例如基带处理单元(Base Band Unit，BBU)、数据交换单元(也称为RHUB)、微射频拉远单元(pico Remote Radio Unit，pRRU)、基站网管子系统等。
其中，BBU作为汇聚节点，BBU连接RHUB，基站网管子系统和BBU连接，RHUB连接pRRU。BBU用于集中控制管理整个基站系统，RHUB实现BBU与pRRU之间的通信，pRRU实现射频信号处理功能。
在目前的综合接入系统中，至少存在如下技术问题：随着BBU小区能力不断提升，BBU作为汇聚节点连接RHUB和基站网管子系统，运营商可以通过基站网管子系统提供基带资源的配置和管理。现有技术中对BBU的射频资源和基带资源的管理都是共用同一个基站网管子系统，从而不同资源之间的配置和管理无法解耦，导致业务开通和业务升级也无法解耦，使得现有技术中的综合接入系统存在可靠性和可维护性都很低的问题。
发明内容
本申请实施例提供了一种综合接入系统、配置方法和基带处理单元，用于实现综合接入系统的内部解耦合，提供综合接入系统的可靠性和可维护性。

具体实施方式
本申请实施例提供了一种综合接入系统和基于综合接入系统的配置方法，用于实现综合接入系统的内部解耦合，提供综合接入系统的可靠性和可维护性。
下面结合附图，对本申请的实施例进行描述。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，这仅仅是描述本申请的实施例中对相同属性的对象在描述时所采用的区分方式。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，以便包含一系列单元的过程、方法、系统、产品或设备不必限于那些单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它单元。
以下分别进行详细说明。
本申请实施例提供的综合接入系统适用于在单运营商和多运营商统一运维的场景，该综合接入系统可以支持分运营商独立射频(Radio Frequency，RF)信源馈入，支持面向未来大容量及第五代移动通信技术(5th-Generation，5G)场景下的数字信号源的馈入。本申请实施例提供的综合接入系统中使用分布式BBU，至少采用两类BBU：第一BBU和第二BBU，从而使得单个的BBU可以连接各自的网管子系统，实现综合接入系统内的解耦合。请参阅如图2所示，本申请实施例提供的一种综合接入系统100，可以包括：第一BBU101、第二BBU102、第一数据交换单元103、第一基站网管子系统104、第二基站网管子系统105、第一pRRU106，其中，
第一BBU101和第一数据交换单元103相连接，第一BBU101和第一基站网管子系统104相连接，第一BBU101和第二BBU102相连接；
第二BBU102和第二基站网管子系统105相连接；
第一pRRU106和第一数据交换单元103相连接。
其中，本申请实施例提供的综合接入系统中采用至少两类BBU：第一BBU101和第二BBU102，第一BBU101和第二BBU102之间可以通过光纤通道连接，例如，该光纤通道具体可以包括：CPRI通道和媒体访问控制(Media Access Control，MAC)通道。第一BBU101可以通过操作管理(Operate Management，OM)通道连接第一基站网管子系统104，第一基站网管子系统104是用于管理第一BBU的网管子系统，第一基站网管子系统可提供射频馈入功能，提供对第一数据交换单元对应的资源、第一pRRU对应的资源的切片功能，提供第一BBU和第二BBU之间的框间互联功能。第二BBU102通过OM通道和第二基站网管子系统105相连接，运营商可以通过第二基站网管子系统105对基带资源进行配置和管理。
本申请实施例中第一BBU101作为主BBU，可以设置在楼宇内，第二BBU102作为从 BBU，可以设置在中心机房内，因此可以实现主从BBU的分布式设计。第一BBU101连接有第一基站网管子系统104，通过该第一基站网管子系统104可以实现对射频资源的配置和管理，第二BBU102连接有第二基站网管子系统105，从而第二基站网管子系统105可以根据运营商的要求配置基带资源。通过主从BBU的分布式设计，可以实现综合接入系统内的解耦合，运营商的运营维护只需要通过基站网管子系统就可以完成，提高了综合接入系统的可靠性和可维护性。
在本申请的一些实施例中，第一BBU和第二BBU根据各自的功能需要使用的组成结构，第一BBU可以包括：射频板、接口板、主控板和直流电源(Direct Current，DC)，第二BBU可以包括：基带板、主控板、DC。第一BBU的接口板可以分别连接第一数据交换单元、第二BBU的基带板，第一BBU的主控板可以连接第一基站网管子系统，第二BBU的主控板可以连接第二基站网管子系统。在本申请的另一些实施例中，第二BBU除了包括基带板、主控板、DC之外，还可以包括接口板，则第一BBU的接口板可以连接第二BBU的接口板。
需要说明的是，在本申请的一些实施例中，第一BBU101和第一数据交换单元103之间可以采用光纤通道相连接，该光纤通道具体可以包括：CPRI通道和MAC通道，第一数据交换单元103具体可以为远端CPRI数据交换单元，在后续实施例中也可以称为“RHUB”。RHUB可以实现第一BBU101与第一pRRU106之间的通信，第一pRRU106实现射频信号处理功能。
在本申请的一些实施例中，请参阅如图3所示，综合接入系统100，还包括：第三BBU107和第三基站网管子系统108，其中，
第一BBU101和第三BBU107相连接；
第三BBU107和第三基站网管子系统108相连接。
其中，第一BBU101和第三BBU107之间可以通过光纤通道连接，例如，该光纤通道具体可以包括：CPRI通道和MAC通道。第三BBU107可以通过OM通道连接第三基站网管子系统108，运营商可以通过第三基站网管子系统108对基带资源进行配置和管理。
在本申请的上述实施例中，综合接入系统100内设置有第一BBU101作为主BBU，还设置有第二BBU102和第三BBU107均作为从BBU，并且第二BBU102和第三BBU107分别连接有各自的基站网管子系统，例如第二BBU102和第二基站网管子系统105相连接，第三BBU107和第三基站网管子系统108相连接，因此在多运营商共建共享场景下，不同的运营商可以分别使用第二基站网管子系统和第三基站网管子系统，从而可以实现多运营商之间的资产解耦，运营维护解耦，业务开通和升级解耦。其中，综合接入系统100内包括的从BBU可以不局限于第二BBU和第三BBU，当综合接入系统内与第一BBU(即主BBU)通过光纤通道连接多个从BBU时，每个从BBU都可以单独连接一个基站网管子系统，对于不同的运营商，每个运营商可以分别使用一个基站网管子系统，各个运营商之间是相互解耦的，从而运营商之间互不干涉。
如图5所示，为本申请实施例提供的一种综合接入系统的系统架构部署示意图。综合接入系统内设置有一个主BBU和三个从BBU(从BBU1、从BBU2和从BBU3)，主BBU设置在远端的楼宇内，三个从BBU设置在近端的中心机房内，主BBU包括有射频板R、 接口板、主控板、DC，主BBU的接口板分别连接从三个从BBU的基带板，主BBU的接口板还通过CPRI通道和MAC通道连接RHUB，RHUB通过CPRI通道的电接口(也称为CPRI-E)连接pRRU，或者RHUB也可以通过MAC通道的电接口连接pRRU。主BBU的主控板连接室分网络统一管理子系统(图5中缩写为BTS(R))。主BBU的射频板R分别连接射频拉远单元(Remote Radio Unit，RRU)，图5中以综合接入系统内设置还有三个RRU为例，三个RRU分别为RRU-A、RRU-B和RRU-C，其中每个RRU都支持全球移动通信系统(Global System for Mobile communication，GSM)、通用移动通信系统(Universal Mobile Telecommunications System，UMTS)、长期演进(Long Term Evolution，LTE)、码分多址(CodeDivisionMultipleAccess，CDMA)，即图5中所示的“G/U/L/C”。每个从BBU包括有基带板和主控板，从BBU的基带板连接主BBU的接口板，从BBU的主控板分别连接基带网管子系统(图5中缩写为BTS(UL))，例如从BBU1的主控板通过OM通道连接一个基站网管子系统，运营商A可以通过该基站网管子系统对基带资源进行配置和管理。从BBU2的主控板通过OM通道连接一个基站网管子系统，运营商B可以通过该基站网管子系统对基带资源进行配置和管理。从BBU3的主控板通过OM通道连接一个基站网管子系统，运营商C可以通过该基站网管子系统对基带资源进行配置和管理。本申请实施例通过支持多个从BBU汇聚到主BBU，实现多运营商分BBU的单个接入，解决运营商间运维解耦问题，适用于面向未来的大容量演进和5G演进的场景。
在本申请的一些实施例中，请参阅如图5所示，综合接入系统，还包括：第四BBU109、第二数据交换单元110、第四基站网管子系统111、第二pRRU112，其中，
第四BBU109和第二数据交换单元110相连接，第四BBU109和第四基站网管子系统111相连接，第四BBU109和第二BBU102相连接；
第二pRRU112和第二数据交换单元110相连接。
其中，综合接入系统中可以采用第一BBU101和第四BBU109都作为主BBU，例如第一BBU101和第四BBU109可以分别设置在不同的楼宇内，第一BBU101和第四BBU109可以分别使用不同的光纤通道连接第二BBU102，第二BBU102可以设置在中心机房内，从而可以支持多个主BBU对从BBU的框间互联，解决一个中心机房覆盖周边多栋楼宇的问题。
需要说明的是，在本申请的上述实施例中，若需要接入多个运营商，则每个运营商都可以使用一个从BBU和一个基站网管子系统，若有多个主BBU时，每个主BBU都可以使用分别连接所有的从BBU，连接方式详见前述第一BBU101和第四BBU109分别与第二BBU102的连接方式。
如图6所示，为本申请实施例提供的另一种综合接入系统的系统架构部署示意图。综合接入系统内设置有三个主BBU和三个从BBU(从BBU1、从BBU2和从BBU3)，主BBU0设置在远端的楼宇0内，主BBU1设置在远端的楼宇1内，主BBU2设置在远端的楼宇2内。三个从BBU设置在近端的中心机房内。以楼宇0内设置的主BBU为例，主BBU包括有射频板R、接口板、主控板、DC，主BBU的接口板分别连接从三个从BBU的基带板，主BBU的接口板还通过CPRI通道和MAC通道连接RHUB，RHUB通过CPRI-E接口或者MAC通道的电接口连接pRRU，主BBU的主控板连接室分网络统一管理子系统(图5 中缩写为BTS(R))。主BBU的射频板R分别连接RRU，图6中以综合接入系统内设置还有三个RRU为例，三个RRU分别为RRU-A、RRU-B和RRU-C。通过图6所示，在综合接入系统内可以设置多个主BBU，也可以设置多个从BBU，因此可以支持多个主BBU对从BBU的框间互联，解决一个中心机房覆盖周边多栋楼宇的问题。
通过前述对本申请实施例提供的综合接入系统的组成结构的说明可知，综合接入系统内包括有两类BBU：第一BBU和第二BBU，第一BBU和第二BBU之间相连接，从而进行BBU间的通信。另外第一BBU和第一基站网管子系统相连接，第二BBU和第二基站网管子系统相连接，因此可以通过第一基站网管子系统可以对第一BBU进行射频资源的单独配置和管理，通过第二基站网管子系统可以对第二BBU进行基带资源的单独配置和管理，因此可以实现射频资源和基带资源的独立管理，综合接入系统的可靠性和可维护性得到很大提高。
前述实施例介绍本申请实施例提供的综合接入系统，接下来介绍基于前述的综合接入系统的配置方法，该方法可以实现综合接入系统内的时钟配置。本申请实施例提供的配置方法适用于综合接入系统，如图2所示，该综合接入系统，包括：第一BBU和第二BBU，第一BBU和第二BBU相连接，例如第一BBU和第二BBU之间通过光纤通道连接，如图7所示，本申请实施例提供的配置方法可以包括如下步骤：
701、第一BBU获取第一时钟同步信息，第一时钟同步信息包括：第一BBU的时钟频率和时钟相位。
702、第一BBU向第二BBU发送第一时钟同步信息。
其中，第一BBU作为主BBU，第一BBU需要向第二BBU提供参考时钟，第二BBU根据第一BBU提供的参考时钟可以校正第二BBU的本地时钟，从而可以实现跨BBU的框间时钟同步。其中，第一BBU可以从本地时钟源获取到第一BBU的时钟频率和时钟相位，然后第一BBU向第二BBU发送第一时钟同步信息。另外，第一BBU还可以与时钟服务器交互，从时钟服务器获取到时钟频率和时钟相位，然后第一BBU根据该时钟频率和时钟相位校正第一BBU的本地时钟源，例如可以使用锁相环路(Phase-Locked Loop，PLL)进行反馈控制，利用时钟服务器提供的外部参考信号控制环路内部时钟信号的频率和相位。第一BBU和第二BBU之间可以通过光纤通道连接，该光纤通道具体可以包括：CPRI通道和MAC通道，第一BBU可以将第一时钟同步信息携带在CPRI帧上，然后通过CPRI通道发送给第二BBU，或者第一BBU也可以将第一时钟同步信息携带在MAC帧上，然后通过MAC通道发送给第二BBU。
在本申请的一些实施例中，结合图3所示，若综合接入系统，还包括：第三BBU，第三BBU和第一BBU相连接，在这种实现场景下，本申请实施例提供的综合接入系统的配置方法，还可以包括如下步骤：
A1、第一BBU向第三BBU发送第一时钟同步信息。
其中，第一BBU作为主BBU连接两个从BBU时，第一BBU在获取到第一时钟同步信息之后，第一BBU可以向第二BBU、第三BBU分别发送第一时钟同步信息，使得第三BBU作为从BBU，也可以收到第一BBU的第一时钟同步信息，该第三BBU可以使用该第一时钟同步信息校正第三BBU的本地时钟源，从而可以实现跨BBU的框间时钟同步。
需要说明的是，在本申请的前述实施例中从第一BBU侧描述了时钟同步的过程，可以理解的是，前述第四BBU所执行的方法与第一BBU所执行的方法相类似，第四BBU可以生成第二时钟同步信息，然后第四BBU向第二BBU发送该第二时钟同步信息，该第二时钟同步信息包括：第四BBU的时钟频率和时钟相位。
通过前述图7所示的时钟配置过程的举例说明可知，第一BBU可以向第二BBU发送第一时钟同步信息，使得第二BBU能够根据该第一时钟同步信息配置第二BBU的本地时钟信息，从而可以实现跨BBU的框间时钟同步。举例说明，通过对BBU模式的配置，通过基站网管子系统的OM通道可以配置第一BBU为主BBU模式，配置第二BBU为从BBU模式。通过支持多BBU的框间汇聚，实现多运营商分BBU接入，解决运营商间运维解耦问题，以及面向未来的基于BBU接入的大容量演进。另外，本申请实施例中还支持多个主BBU对多个从BBU的框间互联，解决一个中心机房覆盖周边多栋楼宇的问题。
前述实施例从第一BBU一侧介绍了基于前述的综合接入系统的配置方法，接下来从第二BBU一侧介绍本申请实施例提供的基于综合接入系统的配置方法，该方法可以实现综合接入系统内的时钟配置。本申请实施例提供的配置方法适用于综合接入系统，如图2所示，该综合接入系统，包括：第一BBU和第二BBU，第一BBU和第二BBU相连接，例如第一BBU和第二BBU之间通过光纤通道连接，如图8所示，本申请实施例提供的配置方法可以包括如下步骤：
801、第二BBU接收第一BBU发送的第一时钟同步信息，第一时钟同步信息包括：第一BBU的时钟频率和时钟相位。
其中，第二BBU和第一BBU之间通过光纤通道连接，第一BBU向第二BBU发送第一时钟同步信息，第二BBU可以通过该光纤通道接收到第一时钟同步信息，第二BBU解析该第一时钟同步信息，可以到第一BBU的时钟频率和时钟相位。
802、第二BBU根据第一时钟同步信息配置第二BBU的本地时钟信息。
其中，第二BBU从第一BBU获取到第一时钟同步信息之后，第二BBU以第一BBU的时钟频率和时钟相位作为参考时钟源，校正第二BBU的本地时钟信息。举例说明，第二BBU可以使用PLL进行反馈控制，利用第一BBU提供的外部参考信号控制环路内部时钟信号的频率和相位。
在本申请的一些实施例中，综合接入系统还包括：第四BBU，第四BBU和第二BBU相连接，在本申请的前述实施例中描述了第四BBU所执行的方法，第四BBU可以生成第二时钟同步信息，然后第四BBU向第二BBU发送该第二时钟同步信息，该第二时钟同步信息包括：第四BBU的时钟频率和时钟相位。在这种场景下，本申请实施例提供的配置方法除了执行前述步骤之外，还包括：
B1、第二BBU接收第四BBU发送的第二时钟同步信息，第二时钟同步信息包括：第四BBU的时钟频率和时钟相位。
其中，第二BBU除了接收到第一时钟同步信息，第二BBU还接收到第四BBU的第二时钟同步信息，第二BBU解析该第二时钟同步信息，可以到第四BBU的时钟频率和时钟相位。第二BBU和第四BBU都作为主BBU时，可以分别向作为从BBU的第二BBU发送时钟同步信息，则第二BBU可以分别获取到第一BBU的时钟频率和时钟相位、第四BBU 的时钟频率和时钟相位。
在前述执行步骤B1的实现场景下，步骤802第二BBU根据第一时钟同步信息配置第二BBU的本地时钟信息，包括：
C1、第二BBU根据第一时钟同步信息、第二时钟同步信息配置第二BBU的本地时钟信息。
其中，第二BBU分别获取到第一时钟同步信息和第二时钟同步新增时，第二BBU可以得到第一BBU的时钟频率和时钟相位、第四BBU的时钟频率和时钟相位，第二BBU通过这两个主BBU的时钟同步信息确定第二BBU的本地时钟信息。其中，第二BBU配置本地时钟信息的方式可以有多种，举例说明如下，步骤C1第二BBU根据第一时钟同步信息、第二时钟同步信息配置第二BBU的本地时钟信息，包括：
C11、第二BBU从第一时钟同步信息和第二时钟同步信息中选择出时钟质量较高的时钟同步信息，并根据时钟质量较高的时钟同步信息配置第二BBU的本地时钟信息。
其中，对于第一BBU和第四BBU分别发送给第二BBU的时钟同步信息，第二BBU可以选择出时钟质量较高的时钟同步信息，并根据时钟质量较高的时钟同步信息配置第二BBU的本地时钟信息。其中，时钟质量是指时间源的时钟信号质量，时钟质量可以通过时钟源的稳定度来衡量，也可以通过时钟源的准确度来衡量，或者通过时钟源的稳定度和准确度来衡量，其中，时钟源有两个重要指标，一个是稳定度，一个是准确度。准确度是指与标称值的偏差，稳定度是指随外部因素变化而产生的变化量。举例说明，稳定度和准确度越高，时钟源具有越高的时钟质量。不限定的是，在本申请的一些实施例中，第二BBU根据第一时钟同步信息、第二时钟同步信息配置第二BBU的本地时钟信息，除了前述的举例说明之外，第二BBU还可以从第一时钟同步信息和第二时钟同步信息中选择出稳定度较高的时钟同步信息，并根据稳定度较高的时钟同步信息配置第二BBU的本地时钟信息。选择稳定度较高的时钟同步信息作为第二BBU的本地时钟信息，可以保证第二BBU的时钟稳定度。
通过前述图8所示的时钟配置过程的举例说明可知，第一BBU可以向第二BBU发送第一时钟同步信息，使得第二BBU能够根据该第一时钟同步信息配置第二BBU的本地时钟信息，从而可以实现跨BBU的框间时钟同步。
接下来对图7和图8所示的时钟配置过程进行举例说明，请参阅图4所示，以主BBU和从BBU之间的时钟同步为例进行说明，本申请实施例可以实现基于面板CPRI互联的框间时钟软同步，即主BBU通过框间的光纤，通过CPRI帧或者MAC帧，把主BBU的时钟频率和相位信息传递给从BBU。首先对BBU进行模式选择，将第一BBU的模式配置为主(Host)BBU模式，将第二BBU的模式配置为从(Client)BBU模式，对于本申请实施例提供的综合接入系统，BBU通过基站网管子系统的OM通道，可以配置为主BBU，或者配置为从BBU。
通过室分网络统一管理子系统对主BBU进行配置，从主BBU的本地时钟源获取时钟，并把时钟同步信息，通过互联的光纤(即CPRI通道或者MAC通道)广播给其他的从BBU。当BBU配置为从BBU时，从互联的光纤(CPRI通道或者MAC通道)恢复出时钟，从BBU将恢复出的时钟作为从BBU的参考时钟源，实现跨框的时钟同步。
前述实施例介绍本申请实施例提供的综合接入系统，接下来介绍基于前述的综合接入系统的配置方法，该方法可以实现综合接入系统内的上层通信通道建立。本申请实施例中主从BBU之间的上层通信通道可以自动建立，不需要人工配置，减少人工成本以及出错的概率。本申请实施例提供的配置方法适用于综合接入系统，如图2所示，该综合接入系统，包括：第一BBU和第二BBU，第一BBU和第二BBU相连接，例如第一BBU和第二BBU之间通过光纤通道连接，如图9所示，本申请实施例提供的配置方法可以包括如下步骤：
901、第一BBU更新第一线速率，并在每次更新之后以更新后的第一线速率向所述第二BBU发送数据帧。
其中，第一BBU使用的线速率定义为“第一线速率”，第二BBU使用的线速率定义为“第二线速率”，其中，线速率是指物理层通道的线路速率。第一BBU不断的更新第一线速率，即第一BBU更新第一线速率的速率取值，并且在每次更新之后都以更新后的第一线速率向所述第二BBU发送数据帧。同样的，第二BBU不断的更新第二线速率，即第二BBU更新第二线速率的速率取值，并且在每次更新之后都向第一BBU发送更新后的基于第二线速率的数据帧。

其中，第一BBU和第二BBU都以各自的周期来更新各自的线速率值，第一周期和第二周期是不相同的周期，因此第一周期和第二周期中必定有一个长周期、一个短周期，通过第一BBU和第二BBU的周期性更新各自的线速率，可以实现第一BBU和第二BBU之间的线速率盲匹配尝试，从而实现线速率的自协商，无需占用人工的资源进行手动配置。
902、第一BBU接收第二BBU在每次更新第二线速率之后以更新后的第二线速率发送的数据帧。
其中，第二BBU在每次更新之后都向第一BBU发送更新后的基于第二线速率的数据帧，则第二BBU通过光纤通道不断的向第一BBU发送基于第二线速率的数据帧，第一BBU接收第二BBU不断发送的基于第二线速率的数据帧，第一BBU需要判断发送出去的第一线速率和接收到的第二线速率是否相等，若两者相等时触发后续步骤903，若两者不相等时继续执行步骤901和步骤902。
903、当第一线速率与第二线速率相等时，第一BBU使用第一线速率向第二BBU发送第一BBU的组网关系信息，以及接收第二BBU使用第二线速率发送的第二BBU的组网关系信息。
其中，在第一BBU发送的第一线速率和接收到的第二线速率相等时，说明第一BBU和第二BBU之间完成速率协商，此时第一BBU可以使用第一线速率向第二BBU发送第一BBU的组网关系信息，以及接收第二BBU使用第二线速率发送的第二BBU的组网关系信息。其中，第一BBU的组网关系信息是指第一BBU连接的BBU的个数，以及所连接的接口板上的端口，第二BBU的组网关系信息是指第二BBU连接的BBU的个数，以及所连接的基带板或者接口板上的端口。第一BBU和第二BBU之间相互交换各自的组网关系信息，使得第一BBU和第二BBU都可以根据双方的组网关系信息生成网络拓扑图，通过该网络 拓扑图可以方便的获取多BBU的框间互联关系。

905、第一BBU根据第二BBU的通信地址与第二BBU建立双向的上层通信通道。
其中，第一BBU为第二BBU分配通信地址，第一BBU可以获取到该第二BBU的通信地址，第二BBU也可以获取到第一BBU的通信地址，从而两个BBU之间可以建立双向的上层通信通道，该上层通信通道可用于第一BBU和第二BBU之间的相互通信，例如第一BBU基于该上层通信通道向第二BBU分配资源。
通过前述图9所示的上层通信通道的建立过程的举例说明可知，第一BBU和第二BBU之间可以进行线速率的自协商，第一BBU向第二BBU分配通信地址，并且第二BBU可以获取到第一BBU的通信地址，第一BBU根据第二BBU的通信地址与第二BBU建立双向的上层通信通道。第一BBU和第二BBU之间通过线速率的自协商、组网关系信息的交换以及通信地址的分配，可以完成上层通信通道的自动建立，不需要人工配置，减少人工成本以及出错的概率。举例说明，主BBU和从BBU之间的上层通信通道自建立，减少了服务人员的配置工作量以及开站的复杂度。

其中，第一BBU和第二BBU都以各自的周期来更新各自的线速率值，第一周期和第二周期是不相同的周期，因此第一周期和第二周期中必定有一个长周期、一个短周期，通过第一BBU和第二BBU的周期性更新各自的线速率，可以实现第一BBU和第二BBU之间的线速率盲尝试，从而实现线速率的自协商，无需占用人工的资源进行手动配置。
1002、第二BBU接收第一BBU在每次更新第一线速率之后以更新后的第一线速率发送的数据帧。
其中，第一BBU在每次更新之后都以更新后的第一线速率向所述第二BBU发送数据帧，则第一BBU通过光纤通道不断的向第二BBU发送基于第一线速率的数据帧，第二BBU接收第一BBU不断发送的基于第一线速率的数据帧，第二BBU需要判断发送出去的第二线速率和接收到的第一线速率是否相等，若两者相等时触发后续步骤1003，若两者不相等时继续执行步骤1001和步骤1002。
1003、当第二线速率与第一线速率相等时，第二BBU使用第二线速率向第一BBU发送第二BBU的组网关系信息，以及接收第一BBU使用第一线速率发送的第一BBU的组网关系信息。
其中，在第二BBU发送的第二线速率和接收到的第一线速率相等时，说明第一BBU和第二BBU之间完成速率协商，此时第二BBU可以使用第二线速率向第一BBU发送第二BBU的组网关系信息，以及接收第一BBU使用第一线速率发送的第一BBU的组网关系信息。其中，第一BBU的组网关系信息是指第一BBU连接的BBU的个数，以及所连接的接口板上的端口，第二BBU的组网关系信息是指第二BBU连接的BBU的个数，以及所连接的基带板或者接口板上的端口。第一BBU和第二BBU之间相互交换各自的组网关系信息，使得第一BBU和第二BBU都可以根据双方的组网关系信息生成网络拓扑图，通过该网络拓扑图可以方便的获取多BBU的框间互联关系。
在本申请的一些实施例中，当第一线速率与第二线速率相等时，除了执行前述步骤1003，本申请实施例提供的方法还可以包括：

1004、第二BBU获取第一BBU的通信地址。
在本申请的实施例中，第一BBU和第二BBU之间相互交换各自的组网关系信息之后，第一BBU根据第二BBU的组网关系信息为第二BBU分配通信地址，向第二BBU发送第一BBU的通信地址，使得第二BBU能够获取到第一BBU的通信地址，其中，通信地址可以是BBU所在位置的位置标识符。
1005、第二BBU根据第一BBU的通信地址与一BBU建立双向的上层通信通道。
其中，第一BBU为第二BBU分配通信地址，第一BBU可以获取到该第二BBU的通信地址，第二BBU也可以获取到第一BBU的通信地址，从而两个BBU之间可以建立双向的上层通信通道，该上层通信通道可用于第一BBU和第二BBU之间的相互通信，例如第一BBU基于该上层通信通道向第二BBU分配资源。
通过前述图10所示的上层通信通道的建立过程的举例说明可知，第一BBU和第二BBU之间可以进行线速率的自协商，第一BBU向第二BBU分配通信地址，并且第二BBU可以获取到第一BBU的通信地址，第一BBU根据第二BBU的通信地址与第二BBU建立双向的上层通信通道。第一BBU和第二BBU之间通过线速率的自协商、组网关系信息的交换以及通信地址的分配，可以完成上层通信通道的自动建立，不需要人工配置，减少人工成本以及出错的概率。
接下来对图9和图10所示的上层通信通道的建立过程进行举例说明，请参阅图11所示，为主BBU和从BBU之间的上层通信通道自建立的过程。主BBU的端口模式设置为主BBU模式，从BBU的端口模式设置为从BBU模式。以主BBU和从BBU之间采用CPRI通道为例，主BBU和从BBU以不同的周期切换CPRI通道的线速率，达成线速率自协商，速率免配，减少人工成本及出错的概率。主BBU和从BBU通过CPRI L1控制字交换组网关系信息，实现互联网络拓扑自发现。主BBU对从BBU分配通信地址，双方按给定的通信地址，在发现的CPRI通道上建立双向的上层通信通道，客户界面通道免配置。
前述实施例介绍本申请实施例提供的综合接入系统，接下来介绍基于前述的综合接入系统的配置方法，该方法可以实现综合接入系统内的资源配置。本申请实施例中主BBU可以向从BBU分配资源。本申请实施例提供的配置方法适用于综合接入系统，如图2所示，该综合接入系统，包括：第一BBU、第二BBU、第一数据交换单元、第二基站网管子系统、第一pRRU，第一BBU分别和第二BBU、第一数据交换单元相连接，第一数据交换单元和第一pRRU相连接，第二BBU和第二基站网管子系统相连接。如图12所示，本申请实施例提供的配置方法可以包括如下步骤：
1201、第一BBU对第一数据交换单元对应的资源以及第一pRRU对应的资源进行切片 处理，得到多个扇区设备组对象资源。
其中，第一BBU负责管理数据交换单元(即RHUB)，pRRU等物理共享设备，第一BBU可以对第一pRRU对应的资源和RHUB对应的资源进行切片处理。例如第一BBU对第一pRRU对应的资源和RHUB对应的资源进行虚拟化，将这些资源抽象为资源对象，然后对这些资源对象进行切片处理，将切片处理得到的切片资源定义为多个扇区设备对象资源。其中，扇区设备对象资源是指在室分综合接入系统内一个或多个pRRU在下行传输时采用广播方式发送同一个载波信号，或在上行传输时通过射频合路形成同一个载波信号的资源对象。举例说明，第一BBU作为主BBU，用于管理RHUB对应的资源和pRRU对应的资源，第一BBU将RHUB对应的资源切分为3个射频合路资源切片，第一BBU将pRRU对应的载波资源切分为3个载波资源分片，则一个RHUB的射频合路资源分片和对应的1个或多个pRRU上的载波资源分片组合起来就可以构成一个扇区设备组对象资源，在上述举例场景下，第一BBU可以生成3个扇区设备组对象资源。
在本申请的一些实施例中，第一数据交换单元对应的资源包括：射频合路小区能力资源和传输通道带宽资源，第一pRRU对应的资源包括：射频资源。其中，若第一BBU和第一数据交换单元之间通过CPRI通道连接，则该传输通道带宽资源具体为CPRI带宽资源。其中，射频资源可以包括：网络制式、频段、发射功率、带宽，射频合路小区能力资源是指射频合路小区个数等资源。
1202、第一BBU根据第二基站网管子系统的资源配置请求从多个扇区设备组对象资源中选择出第一扇区设备组对象资源。
其中，第一BBU和第二BBU相连接，第二BBU和第二基站网管子系统相连接，第一BBU可以通过第二BBU获取到第二基站网管子系统的资源配置请求，然后第一BBU从多个扇区设备组对象资源中为第二基站网管子系统选择出第一扇区设备组对象资源。举例说明，第一BBU按各运营商的实际情况在第一BBU侧进行统一的资源分配，例如运营商采用LTE制式、20M带宽，需要建立两个20M物理小区，第一BBU可以根据此运营商的资源配置为其分配扇区设备组对象资源
1203、第一BBU将第一扇区设备组对象资源通知给第二BBU。
在本申请的实施例中，第一BBU通过前述步骤1202选择出第一扇区设备组对象资源之后，第一BBU向第二BBU通知第一扇区设备组对象资源，例如第一BBU和第二BBU之间采用光纤通道，第一BBU可以通过该光纤通道通知第二BBU。第二BBU调用第一BBU侧分配好的资源并进行绑定，例如第一BBU侧分配的射频资源和第二BBU侧的基带资源进行绑定，用以激活对应的BBU小区及相应的业务。第一BBU通过切片处理，实现了RHUB、pRRU等公共资源能够被各运营商设备的独立调用。
在本申请的一些实施例中，除了执行前述的步骤之外，本申请实施例提供的综合接入系统，还包括：第三BBU和第三基站网管子系统，如图5所示，第一BBU和第三BBU相连接，第三BBU和第三基站网管子系统相连接，本申请实施例提供的方法还包括：
H1、第一BBU根据第三基站网管子系统的资源配置请求从多个扇区设备组对象资源中选择出第二扇区设备组对象资源；
H2、第一BBU将第二扇区设备组对象资源通知给第三BBU。
其中，若第一BBU通过光纤通道连接第二BBU和第三BBU，则第一BBU还可以根据第三基站网管子系统的资源配置请求为第三基站网管子系统分配第二扇区设备组对象资源，实现了RHUB、pRRU等公共资源能够被各运营商设备的独立调用。
通过前述图12所示的资源配置过程的举例说明可知，第一BBU对第一数据交换单元对应的资源以及第一pRRU对应的资源进行切片处理，得到多个扇区设备组对象资源，第一BBU根据第二基站网管子系统的资源配置请求为第二基站网管子系统分配第一扇区设备组对象资源，实现了RHUB、pRRU等公共资源能够被各运营商设备的独立调用。
前述实施例从第一BBU一侧介绍了基于前述的综合接入系统的配置方法，接下来从第二BBU一侧进行举例说明，该方法可以实现综合接入系统内的资源配置。本申请实施例中主BBU可以向从BBU分配资源。本申请实施例提供的配置方法适用于综合接入系统，如图2所示，该综合接入系统，包括：第一BBU、第二BBU、第一数据交换单元、第二基站网管子系统、第一pRRU，第一BBU分别和第二BBU、第一数据交换单元相连接，第一数据交换单元和第一pRRU相连接，第二BBU和第二基站网管子系统相连接。如图13所示，本申请实施例提供的配置方法可以包括如下步骤：
1301、第二BBU获取第一BBU通知的第一扇区设备组对象资源。
1302、第二BBU将第一扇区设备组对象资源和第二BBU的基带资源进行绑定，并激活第一扇区设备组对象资源对应的物理小区。
其中，第一BBU和第二BBU之间采用光纤通道，第一BBU可以通过该光纤通道通知第二BBU。第二BBU调用第一BBU侧分配好的资源并进行绑定，例如第一BBU侧分配的射频资源和第二BBU侧的基带资源进行绑定，用以激活对应的BBU小区及相应的业务，这里的基带资源是指基站侧的物理小区资源。第二BBU可以根据第一第一BBU的分配使用相应的扇区设备组对象资源，实现了RHUB、pRRU等公共资源能够被各运营商设备的独立调用。
通过前述图13所示的资源配置过程的举例说明可知，第二BBU获取第一BBU通知的第一扇区设备组对象资源，第二BBU将第一扇区设备组对象资源和第二BBU的基带资源进行绑定，并激活第一扇区设备组对象资源对应的物理小区，实现了RHUB、pRRU等公共资源能够被各运营商设备的独立调用。
接下来对图12和图13所示的资源分配过程进行举例说明，请参阅图14所示，为主BBU和从BBU之间的资源分配过程的一种举例说明。主BBU连接基站网管子系统、RHUB，RHUB连接pRRU。主BBU连接有3个从BBU，分别为从BBU A、从BBU B、从BBU C，每个从BBU分别连接一个基站网管子系统。主BBU用于对RHUB、pRRU物理设备管理。主BBU首先对RHUB对应的资源、pRRU对应的资源进行切片处理，从而可以得到扇区设备组对象资源A(图14中简称为资源A)、扇区设备组对象资源B(图14中简称为资源B)、扇区设备组对象资源C(图14中简称为资源C)。主BBU可以将资源A分配给从BBU A使用，则从BBU A可以进行资源A调用，然后基于该资源A进行BBU业务管理。
本申请实施例提供的综合接入系统可以支持对主BBU连接的RHUB、pRRU的资源池化和虚拟化管理。主BBU负责管理RHUB、PRRU的物理设备，对pRRU和RHUB的资源对象进行虚拟化和切片。主BBU按各运营商的资源请求，在从BBU侧进行统一的资源 分配，在从BBU侧，各从BBU调用主BBU侧分配好的资源并进行绑定，例如主BBU侧分配的射频资源和从BBU侧的基带资源进行绑定，用以激活对应的BBU小区及相应的业务。通过虚拟化和切片，实现了RHUB、pRRU等公共资源能够被各运营商设备的独立调用。
接下来对资源切片的流程进行举例说明，首先通过主建方(主BBU)收集各运营商目标局点的建网诉求。然后根据各运营商建网诉求和实际局点勘测输出资源的分配结果。举例说明首先收集pRRU、RHUB、主BBU个数等物理设备信息。以及具体的pRRU物理点位，以及个物理点位对应的各运营商建网要求统一规划的资源要求，例如对网络制式、频点、带宽、发射功率，以及射频合路小区的要求，根据资源的设计与规划，配置主BBU。通过扇区设备组对象(含制式、频点、带宽、发射功率、pRRU射频合路信息)进行分运营商的资源切片。各从BBU调用主BBU分配的切片资源(即扇区设备组对象资源)，并和本BBU的基带资源进行绑定，建立并激活对应的物理小区，开通业务。
请参阅图15所示，接下来对主BBU向从BBU分配资源的过程进行举例说明。主BBU首先向从BBU发送pRRU和RHUB的资源状态，从BBU向主BBU发送资源申请，主BBU进行资源配额控制，主BBU向从BBU分配资源，从BBU使用主BBU分配的资源进行资源绑定操作，详见前述实施例中资源绑定的说明。主BBU基于对从BBU的资源授权配置，通过上层通信通道对认证的从BBU指派其可用的pRRU对应的资源和RHUB对应的资源。例如，主BBU向从BBU分配射频资源和网络资源，其中，网络资源包括CPRI带宽能力，射频合路小区能力等。本申请实施例支持BBU按业务扩展所需灵活使用资源，主BBU配置和限制从BBU对资源最大使用量，实现共享资源配额管控。
通过前述对资源配置过程的举例说明可知，本申请实施例可以解决主建方(通过主BBU的基站网管子系统配置主BBU)和运营商(通过从BBU的基站网管子系统配置从BBU)之间，以及运营商和运营商间的运维解耦的问题。主建方主要负责室内硬件网络的建设，聚焦在pRRU、RHUB和主BBU的建设，不涉及基带小区的具体业务。运营商分别管理各自的从BBU，聚焦于各自的BBU业务及运维。因此本申请实施例实现了室分公共系统的统一建设，统一运维和各运营商提供各自差异化业务解决方案的解耦，各运营商间的业务开展也实现了解耦，即可以实现独立的BBU版本、小区、业务特性开通等。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请并不受所描述的动作顺序的限制，因为依据本申请，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本申请所必须的。
