具体实施方式
为了使本技术领域技术人员更好地理解本公开的技术方案，下面将结合附图对本公开一个或多个实施例中的技术方案进行清楚、完整地描述，显然，所描述的一个或多个实施例仅仅是本公开一部分实施例，而不是全部实施例。
参照图1所示，本公开的用于NSA的组网装置适用于5G网络与不同于5G网络的其它无线移动网络比如2G/3G/4G的融合，可以在充分利用现有基站资源的基础上引入5G基带处理设备，提高旧有基站的利用率的同时降低基站建设成本。该组网装置根据所匹配的设备性能可以连接4G核心网或者5G核心网。下面将详细地描述本公开的用于NSA的组网装置及用于NSA的组网方法的各个步骤。
实施例一
参照图2所示为本公开的一种用于NSA的组网装置的结构示意图。可以理解的是，本公开的用于NSA的组网装置属于无线通信系统的一部分，属于4G基带处理设备和5G基带处理设备共用一个射频单元实现天线数据的收发。该组网装置包括：第一基带单元10、第二基带单元20和混模射频模块30。
第二基带单元20配置为至少处理5G基带数据，以及第一基带单元10配置为处理不同于5G基带数据的其它基带数据。
第二基带单元20作为5G基带处理设备可以至少处理5G基带数据，第一基带单元10作为其他基带处理设备可以处理2G/3G/4G基带数据，这里的单元可以是一个基带处理设 备或者多个基带处理设备。
在第一基带单元10、第二基带单元20和混模射频模块30之间构建有第一通信链路。
第一基带单元10经由第二基带单元20至混模射频模块30构建有第一通信链路，目的是实现不同于5G基带处理设备比如4G基带处理设备和射频设备的信息传输，可以传输的信息包括信令、不同于5G的基带数据和对应的天线数据。第一通信链路的实现可以在5G基带处理设备上实现其他基带数据的传输。
混模射频模块30的主要功能至少是同时实现4G和5G天线数据的收发，混模射频模块30可以包括多个射频设备，这些射频设备在进行各种级联后并联连接至第二基带单元20上。
第二基带单元20和混模射频模块30之间构建有第二通信链路，区别于第一通信链路实现5G基带处理设备和射频设备的信息传输，可以传输的信息包括信令、5G基带数据和对应的天线数据。
可以看出，第二基带单元20实现了不同于5G基带数据的传输就可以实现同一个混模射频模块接收不同天线数据的双链路传输。
第一基带单元10和第二基带单元20之间构建有主信令链路，用于两个基带单元共享信息。需要说明的是主信令链路传输的均是信令，确保第一基带单元10和第二基带单元20之间信息、资源共享协调工作。
本公开的用于NSA的组网装置中的第一基带单元和第二基带单元共享混模射频模块，第二基带单元通过主信令链路与第一基带单元交互共享信息从而第二基带单元在其自身的互联光口和射频光口上为第一基带单元分配天线数据位置。因此该组网装置可以在利用现有2G/3G/4G基站设备(包括2G/3G/4G基带单元和混模射频模块)的基础上引入5G基带处理设备实现NSA组网，提高现有基站设备的利用率，降低基站建设成本。
参见图5所示，在一些实施例中，本公开的用于NSA的组网装置中，第二基带单元20和混模射频模块30之间配置有第二拓扑关系，第二基带单元20和混模射频模块30之间根据第二拓扑关系通信连接，第一基带单元10和混模射频模块30之间配置有第一拓扑关系，第一拓扑关系和第二拓扑关系设置为一一对应。
拓扑关系的配置目的是确保第二基带单元20和混模射频模块30之间第二通信链路打通的前提下考虑到第一基带单元10经过第二基带单元20至混模射频模块30的第一通信链路的搭建。第二基带单元20和混模射频模块30之间根据第二拓扑关系通信连接，第二基带单元20可以基于第二拓扑关系为基带和混模射频模块30分配资源，打通第二通信链路。
参见图5所示，混模射频模块30可以包括多个射频设备，射频设备的编号RU51、RU11不同是因为分别连接到不同的基带单元，但实际是同一个混模射频模块，图5中连接同一基带单元的射频设备RU的不同编号表示不同编号ID的射频设备，比如射频设备RU51、射频RU52串联连接后配置到第一基带单元10的射频光口1上。本申请采用的是同一个混模射频模块，该混模射频模块分别配置至第一基带单元和第二基带单元，其中混模射频模块与第一基带单元是实配虚连接，混模射频模块与第二基带单元是实配实连接。
正如图5所示，第一基带单元10和混模射频模块30之间配置有第一拓扑关系，第一拓扑关系是虚配链路，即配置后并不实际连接，目的是第一基带单元10根据第一拓扑关系的配置分配基带和混模射频模块30上的资源。
第一拓扑关系包括混模射频模块30中不同射频设备在完成它们内部的级接后分别连接到第一基带单元10的射频光口上的拓扑形状，并且拓扑关系中涉及级联位置的射频设备的型号，以及配置连接至第一基带单元10的射频光口的光口编号。同样地，第二拓扑关系包括混模射频模块30中不同射频设备在完成他们内部的级联后分别连接到第二基带单元20的射频关口上的拓扑形状，拓扑关系中涉及级联位置的射频设备的型号，以及配置连接至第二基带单元20的射频光口的光口编号。
第一拓扑关系和第二拓扑关系设置为一一对应是第一拓扑关系和第二拓扑关系的拓扑形状相同，拓扑关系中涉及级联位置的射频设备的型号相同，以及配置连接至第二基带单元20的射频光口的光口编号对应。这样做的目的是采用相同的拓扑关系分别使得第一基带单元和第二基带单元分配相同的基带和各自对应的混模射频模块的资源，从而为进一步打通第一通信链路做准备。
图中第一基带处理模块BPM(英文全称：Baseband Process Module)和第二BPM分别是第一基带处理模块110和第二基带处理模块210的一个实施例，下文将会详细描述。
参见图5所示，在一些实施例中，本公开的组网装置中，第一基带单元10和第二基带单元20之间配置有第三拓扑关系，第一基带单元10和第二基带单元20之间根据第三拓扑关系设置有通信线路，通信线路中的一条作为主信令链路。
同样地，配置第三拓扑关系的目的在于分别调动第一基带单元10和第二基带单元20分配相应的资源来实现第三拓扑关系，如图5根据第三拓扑关系进行实际连接在第一基带单元10和第二基带单元20之间形成通信线路。
设定其中一条通信线路为主信令链路，用于传输第一基带单元和第二基带单元之间的信令以共享消息。
参见图3、图4和图5所示，本公开的组网装置中，第一基带单元10包括第一基带处理模块110和第一基站控制模块120，第二基带单元20包括第二基带处理模块210和第二基站控制模块220，第一基带处理模块110包括第一信令转发模块111，第二基带处理模块210包括第二信令转发模块211，第一基站控制模块120为第一信令转发模块111在第一通信链路、主信令链路配置信令转发路由，第二基站控制模块220为第二信令转发模块211在第一通信链路、主信令链路、第二通信链路配置信令转发路由。
第一基带单元10(英文全称为：Base Band Unit，缩写BBU)包括第一基带处理模块BPM(英文全称为：Baseband Process Module，缩写BPM)和第一基站控制模块CCM(英文全称为：Clock Control Module，缩写CCM)，所述第一BPM包括第一信令转发模块。30为4&5G混模射频模块(英文全称为：Radio Unit，缩写RU)。第二BBU包括第二BPM和第二CCM，所述第二BPM包括第二信令转发模块。第一BPM完成2G/3G/4G基带数据的处理，实现基带数据和天线数据的转换，天线数据从第一BPM的射频光口输入/输出。第二BPM完成5G基带数据的处理，实现基带数据和天线数据的转换，天线数据从第二BPM的射频光口输入/输出。
第一CCM和第二CCM通过时钟同步线缆连接，第一BPM和第二BPM可以通过光纤通信连接。第一CCM和第二CCM分别完成各自基带单元中的设备管理、时钟管理和传输管理，具体为：
a.设备管理：第一/第二CCM负责各自基带单元中各模块的上电管理、版本加载、通讯链路管理；
b.时钟管理：第一/第二CCM与时钟源进行同步，为各自基带单元提供工作所参考的时钟；
c.传输管理：第一/第二CCM连接核心网，完成业务数据与核心网的传输。
正如上文所述，第一基带处理模块和第二基带处理模块之间的互联光纤中有且只有一条光纤作为主信令链路，用于传递第一基带单元BBU和第二基带单元BBU之间的信令比如设备配置、共享设备状态等信息。第一基带处理模块和第二基带处理模块之间的所有互联光纤都可以传输第一基带单元和混模射频模块之间的信令比如第一基带单元对混模射频模块RU的配置消息。
参见图6所示，在一些实施例中，本公开的组网装置中，主信令链路上的信令包括第一基站控制模块120和第二基站控制模块220之间的信令，第一通信链路上的信令A包括第一基站控制模块120和混模射频模块之间的信令，第二通信链路上的信令B包括第二基站控制模块220和混模射频模块之间的信令，第一信令转发模块111和第二信令转发模块 211配置为分别转发第一基站控制模块120和第二基站控制模块220之间的信令。第一信令转发模块111和第二信令转发模块211配置为分别转发第一基站控制模块120和混模射频模块之间的信令。第二信令转发模块211配置为转发第二基站控制模块220和混模射频模块之间的信令。
第一基带处理模块BPM和第二基带处理模块BPM各有一个信令转发模块。其中第一基带处理模块的第一信令转发模块将第一基站控制CCM发给第二基站控制CCM的信令从主信令链路转发到第二基带处理模块BPM中的第二信令转发模块，由第二信令转发模块再转发至第二基站控制模块CCM，并且从主信令链路收到的第二基站控制模块CCM的信令转发到第一基站控制模块CCM。第一基带处理模块BPM的第一信令转发模块将第一基站控制模块CCM发给混模射频模块RU的信令从互联光纤链路转发到第二基带处理BPM，并将互联光纤链路收到的混模射频模块RU的信令转发到第一基站控制模块CCM。第二基带处理模块BPM中的第二信令转发模块将第二基站控制模块CCM发给第一基站控制模块的信令从主信令链路转发到第一基带处理模块BPM，并将从主信令链路收到的第一基站控制模块CCM的信令转发到第二基站控制模块CCM。第二基带处理模块BPM中的第二信令转发模块将第二基站控制模块CCM发给混模射频模块RU的信令从第二基带单元和混模射频模块之间的射频光纤链路转发给混模射频模块RU，并将射频光纤链路收到的混模射频模块RU发送给第二基带单元的信令转发至第二基站控制模块CCM。另外第二基站控制模块BPM的第二信令转发模块还将互联光纤链路上收到的第一基站控制模块CCM发给混模射频模块RU的信令从射频光纤链路转发给混模射频模块RU，并将射频光纤链路收到的混模射频模块RU发送给第一基带单元的信令通过互联光纤链路转发到第一基带处理模块BPM上。
参见图8所示，在一些实施例中，本公开的组网装置中，第一信令转发模块111配置为通过主信令链路转发第一基站控制模块120和混模射频模块之间的信令至第二基站控制模块220，第二信令转发模块211配置为将第一基站控制模块120和混模射频模块之间的信令在第二基站控制模块220和混模射频模块之间转发。
图8中A’表示暂时占用主信令链路的第一基站控制模块和混模射频模块之间的信令；B’表示暂时占用第二通信链路的第一基站控制模块和混模射频模块之间的信令。第一基带处理模块BPM和第二基带处理模块BPM之间的互联光纤上有且只有一条光纤作为主信令链路，用于传递第一基带单元BBU和第二基带单元BBU之间的信令比如设备配置、共享设备信息等。第一基带单元BBU和第二混模射射频模块RU之间的信令也作为第一基带单元BBU和第二基带单元BBU之间信令的一种通过主信令链路传递，比如第一基站控制模块对混模射频模块RU的配置消息。
参见图5-图8所示，在一些实施例中，本公开的组网装置中，第一基带处理模块110包括第一射频光口和第一互联光口(参见编号1-6，其中仅适用前面三个1-3)，第二基带处理模块包括第二互联光口(参见编号1-3)和第二射频光口(参见编号4-6)，混模射频模块30包括第一射频通道(虚配链路上的射频设备上)，混模射频模块30包括第二射频通道(射频光纤链路上的射频设备上)，第一互联光口与第二互联光口基于第三拓扑关系通信连接，第二射频光口与第二射频通道基于第二拓扑关系通信连接，第二互联光口与第二射频光口配置为一一对应，第一射频光口与第一射频通道基于第一拓扑关系配置为一一对应，其中第一射频光口和第一互联光口为相同的光口比如第一射频光口和第一互联光口共用图中第一BMP的编号1-3的光口。
第一基带处理模块BPM可以至少完成4G基带数据的处理，并且将基带数据转换为天线数据，第一基带处理模块BMP具有互联光口可以与第二基带处理模块BPM交互天线数据。第二基带处理模块BPM完成5G基带数据的处理，实现5G基带数据和天线数据的转换，并且天线数据从射频光口输入输出，射频光口通过射频光纤链路连接混模射频模块。
第二基带处理模块BPM还具有互联光口可以与第一基带处理模块BPM交互第一基带数据的天线数据，并且可以将第一基带处理模块BPM的第一天线数据发送到射频光口上，完成对第一天线数据转发。
第二基带处理模块BPM的互联光口和射频光口一一对应，这里的一一对应是双方数量相同，一一对应过去，天线数据只能在其中一个互联光口和一个射频光口之间收发。第二基带处理模块BMP与混模射频模块RU通过光纤连接，为了区别第一基带处理模块和第二基带处理模块之间的互联光纤连接，这里可以叫做射频光纤连接。
混模射频模块可以是4G&5G混模射频RU，具有2G/3G/4G射频通道和5G射频通道，就是前面说的第一射频通道即为2G/3G/4G射频通道，第二射频通道即为5G射频通道。下行方向将基带单元发来的天线数据从相应的射频通道发送到空中接口，上行方向将空中接口接收到的数据转换为天线数据发送给基带单元。
第一基带处理模块BPM的射频光口和互联光口可以是相同的光口，即射频光口和互联光口共用图5中的编号1-3的光口，天线数据从互联光口(编号1-3的光口)输入输出，与第二基带处理模块交互第一基带处理模块发过来的第一天线数据。
第二基带处理模块BPM有6个光口(编号1-6的光口)。编号1-3的光口是互联光口，编号4-6的光口是射频光口，一个射频光口对应一个互联光口如编号1对4、编号2对5、编号3对6。第二基带处理模块的互联光口与第一基带处理模块BPM交互第一天线数据，并将第一基带处理模块的第一天线数据发送到其本身的射频光口上。2G/3G/4G/5G天线数 据从第二基带处理模块的射频光口输入输出。
第一射频光口与第一射频通道基于第一拓扑关系配置为一一对应，此处的一一对应是根据第一拓扑关系配置第一射频光口和第一射频通道的数量相同，并且一个射频光口对应一个互联光口，如图5所示，ID码为RU_51的射频设备的射频通道配置为与编号1的射频光口一一对应，ID码为RU_61的射频设备的射频通道配置为与编号2的射频光口一一对应。这样配置的目的是第一基带单元为基带和混模射频模块分配资源。
参见图5-图8所示，在一些实施例中，本公开的组网装置中，第一基站控制模块120为混模射频模块30在第一基带处理模块和第一互联光口之间配置第一天线数据路由，第一基站控制模块和第二基站控制模块至少共享第一天线数据路由、混模射频模块的设备信息和第一拓扑关系(参见图中所示虚配链路，包括混模射频模块30的射频设备ID以及第一互联光口的光口编号)和第三拓扑关系后第二基站控制模块210至少为混模射频模块30在第二互联光口和第二射频光口之间配置第三天线数据路由。
第一基带处理模块BPM和第二基带处理模块BPM之间有多条互联光纤即为上文提到的第三拓扑关系包括第一互联光口和第二互联光口各自的光口编号，用于传递第一基带单元BBU和混模射频模块RU之间的第一天线数据。
第一基带单元BBU和混模射频模块RU之间的第一天线数据路由包括两部分：第一基带处理器112到第一基带处理模块BPM的互联光口的第一天线数据路由，以及第二基带处理模块BPM的互联光口到混模射频模块RU的第三天线数据路由。第一天线数据路由由第一基站控制模块CCM配置。第二基带控制模块BPM的互联光口到混模射频模块RU的第三天线数据路由由第二基站控制模块CCM配置。
第二基带处理模块BPM的第二射频光口上的天线数据包括两部分：第二互联光口过来的第一基带处理模块的第一基带处理器112到混模射频模块RU的第一天线数据，第二基带处理模块的第二基带处理器212到混模射频模块RU的第二天线数据。从第二互联光口到第二射频光口的第三天线数据路由以及第二基带处理模块的第二基带处理器212到第二射频光口的第二天线数据路由都由第二基站控制模块CCM配置。
参见图5-图8所示，在一些实施例中，本公开的组网装置中，混模射频模块的设备信息包括混模射频模块的编号ID，第二基站控制模块基于混模射频模块的ID、第一拓扑关系、第二拓扑关系和第三拓扑关系得出混模射频模块的ID与混模射频模块的ID的对应关系后，根据混模射频模块的ID和第一天线数据路由为混模射频模块配置从第二互联光口至第二射频光口的第三天线数据路由，并且为混模射频模块配置从第二基带处理模块至第二射频光口的第二天线数据路由。
第二基站控制模块根据第一拓扑关系、第二拓扑关系、第三拓扑关系和混模射频模块的设备信息得到混模射频模块的射频设备ID与混模射频模块的射频设备ID的对应关系，目的是将混模射频模块的第一天线数据转换成混模射频模块的第三天线数据，根据该对应关系第二基站控制模块分别得到与混模射频模块的射频设备ID一一对应的混模射频模块的射频设备ID，从而建立第三天线数据路由找到一个端点。另外，对于混模射频模块RU来说，由于第二基带处理模块BPM的第二互联光口上的第一天线数据的位置和第一基带处理模块BPM的第一互联光口上的第一天线数据位置一致，第一基站控制模块CCM通过主信令链路将混模射频模块RU在第一互联光口上的第一天线数据位置的信息告知第二基站控制模块CCM，第二基站控制模块根据上述信息为从第二互联光口过来的第一天线数据分配到第二射频光口上的第三天线数据路由。
下面描述组网的大致流程。
在第一基带单元和第二基带单元配置互联光口，并且配置好与混模射频模块、混模射频模块的第一拓扑关系和第二拓扑关系以及第三拓扑关系。
初始化第一信令转发模块和第二信令转发模块，配置主信令链路、第一通信链路和第二通信链路的信令转发路由，混模射频模块RU根据制式建立分别到第一基带单元BBU以及第二基带单元BBU的第一通信链路和第二通信链路。
第一基站控制模块CCM将第三拓扑关系以及互联光口下“虚配”RU的第一拓扑关系通过主信令链路发送给第二基站控制模块CCM。
第二基站控制模块CCM根据第二拓扑关系、第一基站控制模块发送过来的第三拓扑关系以及第一拓扑关系，计算出混模射频模块的射频设备ID与混模射频模块的射频设备RU的ID的对应关系，从而根据该对应关系第二基站控制模块得到与混模射频模块的射频设备ID一一对应的混模射频模块的射频设备ID，将混模射频模块RU的射频设备的ID转换为混模射频模块RU的射频设备的ID，为建立第三天线数据路由找到一个端点。
2G/3G/4G小区建立时，第一基站控制模块为第一基带单元分配混模射频模块RU从第一基带处理模块BPM的第一基带处理器到第一基带处理模块BPM的互联光口的第一天线数据路由，并通过信令将混模射频模块RU在第一互联光口的天线数据位置以RU载波的方式告知第二基站控制模块CCM。
第二基站控制模块CCM为混模射频模块RU分配第二射频光口上的天线数据位置时根据上文转换过来的对应的混模射频模块的射频设备ID分配第三天线数据路由，并且为分配第二天线数据路由。
第一天线数据路由、第二天线数据路由和第三天线数据路由配置完成，小区建立成功。
在一些实施例中，本公开的组网装置中，第一基站控制模块对混模射频模块有关第一基带单元的制式进行配置管理和操作维护。第二基站控制模块对混模射频模块有关第二基带单元的制式进行配置管理和操作维护。第一基站控制模块和第二基站控制模块对与混模射频模块无关第一基带单元和第二基带单元的制式进行配置管理和操作维护。第二基站控制模块对混模射频模块进行版本管理。

在一些实施例中，本公开的组网装置中，混模射频模块基于有关第一基带单元的制式和有关第二基带单元的制式对第一通信链路和第二通信链路进行配置管理和操作维护。
实施例二
参照图9，示出本公开的一种用于NSA的组网方法，适用于包括第一基带单元、第二基带单元和混模射频模块的组网装置。
在步骤10中，配置第二基带单元20至少处理5G基带数据，以及配置第一基带单元10处理不同于5G基带数据的其它基带数据。
第二基带单元20作为5G基带处理设备可以至少处理5G基带数据，第一基带单元10作为其他基带处理设备可以处理2G/3G/4G基带数据，这里的单元可以是一个基带处理设备或者多个基带处理设备。
在步骤20中，在第一基带单元10、第二基带单元20和混模射频模块30之间构建第一通信链路。
第一基带单元10经由第二基带单元至混模射频模块30构建有第一通信链路，目的是实现不同于5G基带处理设备比如4G基带处理设备和射频设备的信息传输，可以传输的信息包括信令、不同于5G的基带数据和对应的天线数据。第一通信链路的实现可以在5G基带处理设备上实现其他基带数据的传输。
混模射频模块30的主要功能至少是同时实现4G和5G天线数据的收发，混模射频模块30可以包括多个射频设备，这些射频设备在进行各种级联后并联连接至第二基带单元上。
在步骤30中，在第二基带单元20和混模射频模块30之间构建第二通信链路。
第二基带单元20和混模射频模块30之间构建有第二通信链路，区别于第一通信链路实现5G基带处理设备和射频设备的信息传输，可以传输的信息包括信令、5G基带数据和对应的天线数据。
可以看出，第二基带单元20实现了不同于5G基带数据的传输就可以实现同一个混模射频模块接收不同天线数据的双链路传输。
在步骤40中，在第一基带单元10和第二基带单元20之间构建主信令链路。
第一基带单元10和第二基带单元20之间构建有主信令链路，用于两个基带单元共享信息。需要说明的是主信令链路传输的均是信令，确保第一基带单元10和第二基带单元20之间信息、资源共享协调工作。
本公开的用于NSA的组网装置中的第一基带单元和第二基带单元共享混模射频模块，第二基带单元通过主信令链路与第一基带单元交互共享信息从而第二基带单元在其自身的互联光口和射频光口上为第一基带单元分配天线数据位置。因此该组网装置可以在利用现有2G/3G/4G基站设备(包括2G/3G/4G基带单元和混模射频模块)的基础上引入5G基带处理设备实现NSA组网，提高现有基站设备的利用率，降低基站建设成本。
在一些实施例中，本公开的组网方法中，混模射频模块包括多个射频设备和射频通道。
参见图10所示，步骤30进一步包括步骤300和步骤310。
在步骤300中，第一基带单元和混模射频模块之间配置第一拓扑关系，第二基带单元和混模射频模块之间配置第二拓扑关系，第一拓扑关系和第二拓扑关系设置为一一对应。
拓扑关系的配置目的是确保第二基带单元20和混模射频模块30之间第二通信链路打通的前提下考虑到第一基带单元经过第二基带单元20至混模射频模块30的第一通信链路的搭建。第二基带单元20和混模射频模块30之间根据第二拓扑关系通信连接，第二基带单元20可以基于第二拓扑关系为基带和混模射频模块30分配资源，打通第二通信链路。
参见图5所示，混模射频模块30可以包括多个射频设备，射频设备的编号RU51、RU11不同是因为分别连接到不同的基带单元所以射频设备的编号不同，实际是同一个混模射频模块，图5中连接同一基带单元的射频设备RU的不同编号表示不同编号ID的射频设备，比如射频设备RU51、射频RU52串联连接后配置到第一基带单元的射频光口1上。本申请采用的是同一个混模射频模块，该混模射频模块分别配置至第一基带单元和第二基带单元，其中混模射频模块与第一基带单元是实配虚连接，混模射频模块与第二基带单元是实配实连接。
正如图5所示，第一基带单元10和混模射频模块30之间配置有第一拓扑关系，第一 拓扑关系是虚配链路，即配置后并不实际连接，目的是第一基带单元10根据第一拓扑关系的配置分配基带和混模射频模块30上的资源。
第一拓扑关系包括混模射频模块30中不同射频设备在完成它们内部的级接后分别连接到第一基带单元10的射频光口上的拓扑形状，并且拓扑关系中涉及级联位置的射频设备的型号，以及配置连接至第二基带单元20的射频光口的光口编号。同样地，第二拓扑关系包括混模射频模块30中不同射频设备在完成他们内部的级联后分别连接到第二基带单元20的射频关口上的拓扑形状，拓扑关系中涉及级联位置的射频设备的型号，以及配置连接至第二基带单元20的射频光口的光口编号。
在步骤310中，第二基带单元和混模射频模块之间根据第二拓扑关系建立通信连接。
第一拓扑关系和第二拓扑关系设置为一一对应是第一拓扑关系和第二拓扑关系的拓扑形状相同，拓扑关系中涉及级联位置的射频设备的型号相同，以及最终连接至第二基带单元20的射频光口的光口编号对应。这样做的目的是采用相同的拓扑关系分别使得第一基带单元和第二基带单元分配相同的基带和各自对应的混模射频模块的资源，从而为进一步打通第一通信链路做准备。
图5中第一基带处理模块BPM(英文全称：Baseband Process Module)和第二BPM分别是第一基带处理模块110和第二基带处理模块210的一个实施例，下文将会详细描述。

实施例三
本公开的一种无线通信系统，包括如上文所述的组网装置。该组网装置包括：第一基带单元10、第二基带单元20和混模射频模块30。
第二基带单元20配置为至少处理5G基带数据，以及第一基带单元10配置为处理不同于5G基带数据的其它基带数据。
第二基带单元20作为5G基带处理设备可以至少处理5G基带数据，第一基带单元10作为其他基带处理设备可以处理2G/3G/4G基带数据，这里的单元可以是一个基带处理设备或者多个基带处理设备。
在第一基带单元10、第二基带单元20和混模射频模块30之间构建有第一通信链路。
第一基带单元10经由第二基带单元20至混模射频模块30构建有第一通信链路，目的是实现不同于5G基带处理设备比如4G基带处理设备和射频设备的信息传输，可以传输的信息包括信令、不同于5G的基带数据和对应的天线数据。第一通信链路的实现可以在5G基带处理设备上实现其他基带数据的传输。
混模射频模块30的主要功能至少是同时实现4G和5G天线数据的收发，混模射频模块30可以包括多个射频设备，这些射频设备在进行各种级联后并联连接至第二基带单元20上。
第二基带单元20和混模射频模块30之间构建有第二通信链路，区别于第一通信链路实现5G基带处理设备和射频设备的信息传输，可以传输的信息包括信令、5G基带数据和对应的天线数据。
可以看出，第二基带单元20实现了不同于5G基带数据的传输就可以实现同一个混模射频模块接收不同天线数据的双链路传输。
第一基带单元10和第二基带单元20之间构建有主信令链路，用于两个基带单元共享信息。需要说明的是主信令链路传输的均是信令，确保第一基带单元10和第二基带单元20之间信息、资源共享协调工作。
本公开的用于NSA的组网装置中的第一基带单元和第二基带单元共享混模射频模块，第二基带单元通过主信令链路与第一基带单元交互共享信息从而第二基带单元在其自身的互联光口和射频光口上为第一基带单元分配天线数据位置。因此该组网装置可以在利用现有2G/3G/4G基站设备(包括2G/3G/4G基带单元和混模射频模块)的基础上引入5G基带处理设备实现NSA组网，提高现有基站设备的利用率，降低基站建设成本。
可以看出，本公开的用于NSA的组网装置将分别至少支持5G基带数据处理的第二基带单元和支持不同于5G基带数据的其它基带数据处理的第一基带单元进行了改造组网，共用同一个混模射频模块实现分别对应第一基带单元和第二基带单元的不同天线数据的收发，混模射频模块可以利用旧有基站的射频模块，第一基带单元也可以利用旧有的2G/3G/4G基带处理设备，即可以充分利用旧有基站的原有设备资源引入5G基带处理设备实现NSA组网，为用户提供5G网络速度的同时充分利用旧有的设备，降低基站建设成本。具体地，可以在在第一基带单元、第二基带单元和混模射频模块之间构建有第一通信链路，在第二基带单元和混模射频模块之间构建有第二通信链路，在第一基带单元和第二基带单元之间构建有主信令链路，通过第一通信链路实现第一基带单元比如4G基站的正常工作，通过第二通信链路实现5G基站的正常工作，并且在第一基带单元和第二基带单元之间构建有用于信息共享的主信令链路，确保两边基站资源共享协调保证组网装置提供5G的网络速度，满足用户的需求。
