本申请实施例中，待匹配位置信息集包括多个第二位置信息，第二位置信息为预先规划的射频单元的可选位置信息，在网络规划阶段，需要预先规划射频单元的多个可选安装位置(即各个第二位置信息对应的位置)，并为各个可选安装位置对应的预设射频单元确定唯一的射频单元标识，该射频单元标识为能够在基站中唯一标识该预设射频单元的参数；将包括多个第二位置信息的待匹配位置信息集、与各个第二位置信息相关联的射频单元标识保存至基带处理单元，本申请实施例不限制基带处理单元获取待匹配位置信息集、射频单元标识的方式，无线通信网管系统中存储了网络规划或网络优化阶段生成的各个预先规划的射频单元的可选安装位置的第二位置信息，基带处理单元可以从无线通信网管系统中获取待匹配位置信息集、射频单元标识；在射频单元工作阶段，射频单元通过向基带处理单元发送第一位置信息，以请求基带处理单元分配射频单元标识，并根据射频单元标识与基带处理单元建立通信连接；由于第一位置信息表征当前射频单元的安装位置，当第一位置信息与待匹配位置信息集中任意一个第二位置信息相匹配，确定该射频单元安装在网络规划阶段中预先规划好的可选安装位置，该射频单元定位成功，获取与第二位置信息对应的射频单元标识，并将该射频单元信息反馈至射频单元，以使射频单元能够根据射频单元标识与基带处理单元建立通信连接。
本申请实施例并不限制射频单元标识的具体数据内容，可以是射频单元设备名称、射频单元位置信息等等，本领域技术人员有动机根据实际情况确定。
另外，参照图2，在一实施例中，第一位置信息包括第一位置编码；图1所示实施例中的步骤S120还包括但不限于有以下步骤S210、S220。
步骤S210，根据各个第二位置信息和预设的第一编码规则确定射频单元的第二位置编码。
步骤S220，当第一位置编码与第二位置编码的重合度小于预设的门限值，获取射频单元 标识。
在本申请实施例中，第二位置信息可以是包括经纬度、高程信息、俯仰角信息的原始位置数据，当待匹配的第一位置信息包括第一位置编码，需要对第二位置信息进行编码计算，得到与第一位置编码格式相同的编码信息，即第二位置编码，为实现第一位置信息与第二位置信息进行快速检索匹配提供有效的数据基础。可以理解的是，预设的门限值表征可允许的第一位置编码与第二位置编码之间重合度的最大误差，当第一位置编码与第二位置编码的重合度小于预设的门限值，可以确定与第一位置编码对应的射频单元安装在网络规划阶段中预先规划好的可选安装位置，该射频单元定位成功，获取与第二位置编码对应的射频单元标识，为射频单元根据射频单元标识与基带处理单元建立通信连接提供有效的数据基础。
本申请实施例并不限制第一位置信息与第二位置信息的进行匹配处理时的数据格式，当第一位置信息的数据形式为包括经纬度、高程信息、俯仰角信息的原始位置数据，第一位置信息与第二位置信息直接进行匹配处理即可，不需进行数据格式转换。
本申请实施例的编码规则可以是将第二位置信息格式化为以预设射频单元为中心，以识别门限距离为半径的各个矩形识别区域，每个矩形识别区域对应一个预设射频单元，按照一般的工程情况，识别门限距离为30至50米即可满足站点识别需要；本申请实施例并不限制第一位置编码以及第二位置编码的具体数据格式，可以是如图20所示的数据编码格式，包括有字节长度为8bit的经度区域码、经度秒、经度分、经度、纬度区域码、纬度秒、纬度分、纬度、俯仰角、水平方位角，以及字节长度为16bit的海拔高度信息，本领域技术人员可以根据实际需求确定。

步骤S410，获取射频单元发送的业务配置请求，业务配置请求携带有设备标识；
步骤S420，根据设备标识获取目标业务配置信息，并根据网络通信地址将目标业务配置信息发送至射频单元。
本申请实施例并不限制射频单元标识中的设备标识和网络通信地址的具体获取方法，对于设备标识，可以参考图1实施例的描述，在基带处理单元中预先设置与第二位置信息关联的设备标识；对于网络通信地址，基带处理单元可以与动态主机配置协议(Dynamic Host Configuration Protocol，DHCP)服务器通信连接，DHCP服务器中存储有与各个设备标识对应的网络通信地址，在第一位置信息与待匹配位置信息集中任意一个第二位置信息相匹配的情况下，基带处理单元从DHCP服务器中获取与设备标识相对应的网络通信地址，从而将设备标识和网络通信地址发送至射频单元，以使射频单元根据网络通信地址与基带处理单元建立通信连接，基带处理单元与射频单元从而可以通过DHCP报文进行相互通信。基带处理单元还可以与网管服务器通信连接，在射频单元与基带处理单元建立通信连接之后，射频单元可以通过网络通信地址向基带处理单元发送业务配置请求，该业务配置请求携带有设备标识，即射频单元发送携带有设备标识的DHCP报文至基带处理单元，基带处理单元通过解封装该DHCP 报文得到设备标识，并从网管服务器中获取与设备标识相对应的目标业务配置信息，根据网络通信地址将携带有目标业务配置信息的DHCP报文反馈至射频单元，从而保证射频单元的业务配置符合网管配置。
本申请实施例并不限制目标业务配置信息的具体内容，可以是符合网关配置的射频单元运行数据、基带数据等。
另外，参照图5，在一实施例中，在一实施例中，在图1所示实施例中的步骤S120之后，通信连接方法还包括但不限于有以下步骤S510、S520。

可以理解的是，射频单元安装于基站天线端，可能会由于自然因素，如风吹雨打等情况，导致基站天线的地理位置信息，例如俯仰角，水平方位角发生变化，基站天线以及射频单元的位置信息变化会影响基站信号的覆盖范围，从而影响终端与基站之间的通信，因此需要实时获取新的第一位置信息，确定射频单元是否处于预先规划好的地理位置中，为保障终端与基站之间良好通信，维持基站信号的覆盖范围提供有效的数据基础；当新的第一位置信息与待匹配位置信息集中任意一个第二位置信息相匹配，说明射频单元仍然位于预先规划的可选安装位置，重新获取新的射频单元标识，并将新的射频单元标识重新发送至射频单元，以使射频单元根据新的射频单元标识与基带处理单元重新建立通信连接；当待匹配位置信息集中不能匹配出与新的第一位置信息相对应的第二位置信息，说明当前射频单元不位于预先规划的可选安装位置，该射频单元与基带处理单元不能建立通信连接。
另外，参照图6，在一实施例中，基带处理单元与至少两个射频单元相连接，至少两个射频单元连接于基带处理单元的同一个通信端口，射频单元为射频单元链路中的首级射频单元，本实施例的通信连接方法还包括但不限于有以下步骤S610、S620。
步骤S610，获取各个射频单元发送的第一位置信息。
步骤S620，当从待匹配位置信息集中匹配出与第一位置信息相对应的第二位置信息，获取射频单元标识，并将射频单元标识发送至射频单元，以使射频单元根据射频单元标识与基带处理单元建立通信连接。
可以理解的是，本申请实施例并不限制至少两个射频单元连接于基带处理单元的同一个通信端口的具体形式，可以是如图16所示，基带处理单元BBU1610的一个通信端口通过分组前传网络连接有多个射频单元1620，包括第一射频单元AAU10，第二射频单元AAU20和第三射频单元AAU30，AAU10、AAU20和AAU30分别为第一射频单元链路、第二射频单元链路和第三射频单元链路的首级射频单元，第一射频单元链路只有一个射频单元AAU10；第二射频单元链路包括AAU20及其级联的射频单元AAU21、AAU22；第三射频单元链路包括AAU30及其级联的射频单元AAU31；还可以是如图17所示，基带处理单元BBU1710的一个通信端口通过网络连接设备1720(如交换机等)与多个射频单元1730(AAU30、AAU40和AAU50)相连接。
由于至少两个射频单元连接于基带处理单元的同一个通信端口，导致连接于同一个通信端口的各个射频单元之间的拓扑关系是局部模糊的，而不是简单呈现为级联的拓扑关系，因此，通过类似控制字的方式下发并逐级传递射频单元标识的方式不再适用；本申请实施例中， 参考图1实施例的描述，在射频单元工作阶段，与基带处理单元的同一个通信接口相连接的各个射频单元通过向基带处理单元发送第一位置信息，以请求基带处理单元分配射频单元标识，并根据射频单元标识与基带处理单元建立通信连接；由于第一位置信息表征当前射频单元的安装位置，当第一位置信息与待匹配位置信息集中任意一个第二位置信息相匹配，确定该射频单元安装在网络规划阶段中预先规划好的可选安装位置，该射频单元定位成功，获取与第二位置信息对应的射频单元标识，并将该射频单元信息反馈至射频单元，以使射频单元能够根据射频单元标识与基带处理单元建立通信连接，能够不再依赖设备之间的物理连接关系，在以太网传输网络中射频单元拓扑模糊的情况下，对同一区域内多台同型号的射频单元具有识别能力。
并且，本实施例中射频单元还可以通过射频单元型号、资产条码编号等标识数据向基带处理单元请求射频单元标识，但是这些标识数据存在区分度低的缺陷，在射频单元通过该标识数据与基带处理单元中规划的预设射频单元进行匹配的过程中，需要严格地核对工勘信息，确保与网管配置信息的一致性，会带来较大的网络建设和维护成本；因此，通过第一位置信息与预先规划的第二位置信息进行匹配处理的方式实现射频单元的定位，不需要施工和维护人员记录复杂的资产序列码，也不需要在系统中核对每台设备的资产序列码与配置的对应关系正确性，可以大大计划网络建设阶段的施工成本和网络维护的维护成本。
