具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
本发明实施例旨在提供一种基于SDR的组网方法、系统，由多个通用硬件模块采用搭积木的方式组成，如图1所示。通用硬件模块按照硬件功能特性定义为三种类型：数字型通用硬件模块、射频型通用硬件模块和供电型通用硬件模块。考虑到通用硬件模块安装配置的全解耦，即在有限的安装空间内可以任意配置通用硬件模块，优选将三种类型的通用硬件模块的结构外形尺寸以及对外的接口设计保持一致，差别仅在于对外接口的功能不一样；并且通用硬件模块内置室外防雷以及IP防护等级，可以支持独立应用，也可以支持多个通用硬件模块拼凑在一起形成更大容量单元。安装方式支持抱杆、挂墙以及入柜等各应用场景。
对于供电型通用硬件模块而言，包括电源转换及配电和电池备电两种功能的配置，对外的接口直接给其它无线设备(也通过通用硬件模块实现)供电，其功能可以通过SDR方式软配置，如图1中Pad-->Power供电设备。
对于数字型通用硬件模块和射频型通用硬件模块而言，其硬件模块功 能也可以通过SDR方式软配置，设备对外接口完成对应功能的定义，如图1所示，数字型通用硬件模块软配置成1个PTN传输设备(SDR-->PTN)、1个以太网交换设备(SDR-->IP Switch)、1个媒体信令流控设备(SDR-->MCH)、2个基带处理设备(SDR-->BP)、1个监控设备(SDR-->Mon)、1个时钟同步设备(SDR-->Clk Sync Div)和1个IQ基带池交换设备(SDR-->IQ Switch)。对于射频型通用硬件模块而言，同样可以通过SDR方式软配置成不同无线制式、不同频段的射频电源RRU，如图1所示(SDR-->RRU1…SDR-->RRUn)。图1给出了多个通用硬件模块定义的完整无线通讯系统，电源模块(Pad-->Power)给其它无线设备供电；PTN传输设备(SDR-->PTN)将从核心网侧的数据解析后通过以太网交换设备(SDR-->IP Switch)传递到媒体信令流处理设备(SDR-->MCH)，以太网数据包IP data通过进一步解析后传递到各基带处理单元进行调制(SDR-->BP)，最后调制后的数字中频传递到射频单元模块，实现无线的下行通讯链路，反之则为上行通讯链路。时钟同步设备(SDR-->Clk Sync Div)主要是给无线系统网络中各设备提供时钟同步，从而满足数据的时隙关系；而IQ基带池交换设备(SDR-->IQ Switch)主要是实现各基带处理单元基带池资源的共享。
图2为本发明实施例的基于SDR的组网方法的流程示意图，如图2所示，所述基于SDR的组网方法包括以下步骤：
步骤201：根据网络功能，确定实现所述网络功能所需的通用硬件模块的数。
参照图1，图1给出了多个通用硬件模块定义的完整无线通讯系统，该系统的网络功能具有供电功能、PTN功能、以太网交换功能、媒体信令流处理功能、基带处理功能、射频功能、时钟同步功能等。每个功能均需要对应的通用硬件模块来现实。因此，根据网络功能，能够确定实现所述网 络功能所需的通用硬件模块的数。
本发明实施例中，所述通用硬件模块包括：数字型通用硬件模块、射频型通用硬件模块、供电型通用硬件模块；
其中，所述数字型通用硬件模块、所述射频型通用硬件模块以及所述供电型通用硬件模块中的一个或多个，具有一致的尺寸和接口。
本发明实施例中，所述通用硬件模块具有室外防雷功能以及入口保护IP防护功能；
所述通用硬件模块的数量为一个时，所述通用硬件模块支持独立应用；
所述通用硬件模块的数量为两个以上时，所述通用硬件模块支持支持组合应用。
这里，IP防护等级的格式为IPXX，其中XX为两个阿拉伯数字，第一个数字表示接触保护和外来物保护等级，第二个数字表示防水保护等级，具体的防护等级可以参考下面的定义。
防尘等级(第一个X表示)
0：没有保护
1：防止大的固体侵入
2：防止中等大小的固体侵入
3：防止小固体进入侵入
4：防止物体大于1mm的固体进入
5：防止有害的粉尘堆积
6：完全防止粉尘进入
防水等级(第二个X表示)
0：没有保护
1：水滴滴入到外壳无影响
2：当外壳倾斜到15度时，水滴滴入到外壳无影响
3：水或雨水从60度角落到外壳上无影响
4：液体由任何方向泼到外壳没有伤害影响
5：用水冲洗无任何伤害
6：可用于船舱内的环境
7：可于短时间内耐浸水(1m)
8：于一定压力下长时间浸水
在一种实现方式中，IP防护等级可以是IP65。
步骤202：对所述网络功能进行分解，得到多个网络子功能。
参照图1，多个网络子功能分别为：供电功能、PTN功能、以太网交换功能、媒体信令流处理功能、基带处理功能、射频功能、时钟同步功能等。
本领域技术任意应当理解，这里以图1所示的完整无线通讯系统为例，但本发明实施例并不局限于此，根据网络所实现的功能不同，通用硬件模块的数量也不同。
步骤203：在所述各个通用硬件模块上，按照SDR方式分别配置所述多个网络子功能，以使所述各个通用硬件模块实现所述网络功能。
本发明实施例中，对于供电型通用硬件模块，按照SDR方式配置至少以下功能：电源转换及配电功能、电池备电功能、接口供电功能。
对于数字型通用硬件模块，按照SDR方式将相应数量的所述数字型通用硬件模块配置为以下设备的任意组合：
PTN传输设备、以太网交换设备、媒体信令流控设备、基带处理设备、监控设备、时钟同步设备、IQ基带池交换设备。
对于射频型通用硬件模块，按照SDR方式将相应数量的所述射频型通用硬件模块配置为预定无线制式、预定频段的RRU。
参照图1，电源模块(Pad-->Power)给其它无线设备供电；PTN传输设备(SDR-->PTN)将从核心网侧的数据解析后通过以太网交换设备 (SDR-->IP Switch)传递到媒体信令流处理设备(SDR-->MCH)，以太网数据包IP data通过进一步解析后传递到各基带处理单元进行调制(SDR-->BP)，最后调制后的数字中频传递到射频单元模块，实现无线的下行通讯链路，反之则为上行通讯链路。时钟同步设备(SDR-->Clk Sync Div)主要是给无线系统网络中各设备提供时钟同步，从而满足数据的时隙关系；而IQ基带池交换设备(SDR-->IQ Switch)主要是实现各基带处理单元基带池资源的共享。
本发明实施例的基于SDR的组网方法，不仅在无线制式上实现了软件的可配置，同时在硬件模块的功能上也实现了软件可配置。通过下载不同的软件版本将通用硬件模块配置成无线网络节点的相关功能，例如：基带处理设备、基站控制设备、IQ基带池交换设备、以太网交换设备、监控设备、PTN传输设备，或者其中某些设备集成在一起等等。由于通用硬件模块本身是自然散热，支持IP防护，可以独立工作于室内、室外，例如：入柜、挂墙、抱杆等安装场景，也可以按照容量需求将多个通用硬件模块进行集中安装，从而实现了硬件设备形态的统一，应用非常灵活。
下面结合具体场景对本发明实施例作进一步描述。

三、抱杆安装方式
通用硬件模块可以抱杆安装。这种安装方式对室内、室外环境都合适，节省空间，安装方便。
图6为本发明实施例的分布式基站组网示意图，如图6所示，将通用硬件模块软配置成基带处理单元，集成了IQ-Switch、媒体信令流程处理和基带处理功能，通过以太网连接到核心网，将数字中频数据连接到射频单元RRU，从而实现一个基站的功能。这种方式是目前3G、4G应用最广的分布式部署。

图8为本发明实施例的超大容量集中部署云处理中心示意图，如图8所示，在需要大容量集中部署时，可以将通用硬件模块进行入柜安装，同时将柜内的通用硬件模块软配置成相同功能，互联从而实现扩容。例如图8所示，将媒体信令以及传输集中在柜内，实现大容量的IP DATA云计算中心；将基带处理单元也集中在柜内，实现大容量的IQ DATA云计算中心。
