下面通过附图及具体实施例对本发明做优选地详细说明。
本发明至少一个实施例提供了一种室内分布系统实现方法， 如图 1 所 示， 该方法包括以下步骤：
步骤 101 : 将室内分布系统信号源覆盖区域划分为内区和外区； 其中， 所述内区由室内分布系统信号源提供信号， 所述外区与室内分布系统信号 源可控连接；
具体地， 在室内区域设置室内分布系统时， 先将室内分布系统信号源 覆盖的室内区域划分为内区和外区； 这里， 所述内区是指室外信号较弱，
即建筑物穿透损耗大于指定门限的区域， 通常将测量获得的室外信号接收 强度低于指定接收强度门限 15~25dB的区域划分为内区； 实际应用中， 一 般会将室内靠近窗口区域的接收强度作为所述指定接收强度门限， 内区一 般为室外信号覆盖较弱的区域， 因此， 在内区中适合一直使用室内分布系 统信号源进行覆盖； 之后， 将除了内区之外的室内其它区域划分为外区， 外区一般为室外信号较强、 室内靠近门窗、 建筑物穿透损耗较小的区域； 优选地， 根据外区所接收到的室外信号所归属的主小区个数， 可将外 区细分为若干个外区子分区；
具体地， 可以根据外区接收到的室外信号所归属的主小区个数为多少， 就将外区划分为与所述主小区个数相等或者更多个数的外区子分区； 例如， 当外区接收到的室外信号仅来自于一个室外小区， 则将外区划分为一个或 一个以上的外区子分区， 如果外区接收到的室外信号来自于三个室外小区， 则将外区划分为三个或者三个以上的外区子分区， 以此类推；
由于外区所接收到的室外信号所归属的主小区的个数是动态变化的， 且这种变化难以预测， 因此， 还可以根据指定的外区子分区面积大小， 将 外区划分为与指定外区子分区面积大小相等的若干个外区子分区；
在实际的应用中， 还可以综合考虑实际需要或室外信号所归属的主小 区覆盖范围等因素， 对应某个室外信号所归属的主小区划分多个外区子分 区， 以便更好地提供高质量的通信信号。
这里， 室外信号接收强度可以由测试人员携带路测终端对目标区域范 围内各个区域的室外信号接收功强度进行测量， 不同区域的室外信号接收 强度是动态变化的， 之后利用路测软件记录测试结果， 并形成接收信号强 度的地理化分布图， 根据信号强度的变化情况， 按照上面介绍的方法将室 内分布系统信号源覆盖区域划分为内区和外区。
在实际应用中， 室内分布系统中通常采用各种制式的移动通信信号，
各种移动通信信号通过频段合路器进行合路之后， 采用移动通信系统的远 端射频单元（RRU， Radio Remote Unit )进行发射， 覆盖至室内区域； 本发 明至少一个实施例中的室内分布系统信号源现阶段就是指所述 RRU; 目前， 也有运营商在室内分布系统中对一种制式的移动通信信号进行单独管理， 也就是说， 在室内分布系统中的信号源不只一个； 相应的， 对于各个室内 分布系统信号源都可以采用本发明至少一个实施例提供的方法进行室内分 布系统的设置。
本发明至少一个实施例中室内分布系统信号源可通过有线方式直接与 内区相连， 或者室内分布系统信号源经过功分器、 或耦合器之后与内区相 连； 也就是说， 本发明至少一个实施例中， 对于室外信号覆盖较弱的内区 一直采用室内分布系统信号源覆盖； 而对于室外信号覆盖较好的外区， 需 要根据室内外信号测量参数进行单独的切换控制。
优选地， 本发明至少一个实施例又将外区划分为多个外区子分区， 通 过对各个外区子分区实现单独控制， 来实现对外区的信号覆盖的精细化控 制。
本发明至少一个实施例中， 室内分布系统信号源通过可控连接器连接 内区和外区， 可以包括但不限于以下三种连接方式：
A ) 第一种连接方式
在第一种连接方式中， 室内分布系统信号源与内区直接相连， 然后通 过内区再连接各个外区子分区， 具体地， 内区分别通过可控连接器与各个 外区子分区相连； 第一种连接方式示意图如图 2所示。
B ) 第二种连接方式
在第二种连接方式中， 室内分布系统信号源通过功率分配器或耦合器 之后， 将信号分为两路， 分别为信号 1和信号 2， 然后将所述信号 1直接与 内区相连， 将所述信号 2分别通过可控连接器连接各个外区子分区； 第二
种连接方式示意图如图 3所示。
C )第三种连接方式
在第三种连接方式中， 室内分布系统信号源直接与内区相连， 并分别 通过可控连接器与各个外区子分区相连； 第三种连接方式示意图如图 4所 示。
具体地， 在本发明至少一个实施例中， 无论采用上述哪一种连接方式， 内区与外区子分区、 或者各个外区子分区与室内分布系统信号源之间均以 有线方式进行连接。
本发明至少一个实施例中所述的可控连接包括但不限于以下两种方 式：
第一种， 通过可控两相开关连接。 具体地， 通过可控两相开关连接时， 能够通过切换可控两相开关中开关的连接状态， 将可控两相开关与室内分 布系统信号源接通或者断开， 可控两相开关的基本结构如图 5 所示； 当所 述可控两相开关开启时， 所述开关连接到外区子分区方向， 则外区子分区 与室内分布系统信号源连通； 当所述可控两相开关关闭时， 所述开关连接 固定匹配负载， 则外区子分区与室内分布系统信号断开。 所述可控两相开 关可以为机械开关或电子控制开关； 其中， 机械开关需要由手动控制， 电 子控制开关可用于自动控制。
第二种， 通过可控衰减器连接。 具体地， 所述可控衰减器的基本结构 如图 6所示， 当所述可控衰减器开启时， 对室内分布系统信号的衰减值最 低（接近零）， 则外区子分区与室内分布系统信号连通； 当所述可控衰减器 关闭时， 对室内分布系统信号的衰减值最高， 则外区子分区与室内分布系 统信号完全断开； 所述衰减器可以为机械控制衰减器或电子控制衰减器， 其中， 机械控制衰减器需要手动控制， 电子控制衰减器可用于自动控制。
优选地， 本发明至少一个实施例还可以通过设置频率筛选电路来控制
外区子分区与不同频段的室内分布系统信号相连通； 具体地， 在室内分布 系统信号源与外区子分区之间的连接线路上设置频段分路器、 可控连接器 以及频段合路器， 所述频段分路器、 可控连接器以及频段合路器的设置方 式如图 7 所示， 从室内分布系统信号源过来的信号， 经过一个频段分路器 之后形成两条分路， 分别为上分路和下分路， 上分路上为指定频段的室内 分布系统信号， 下分路上为其他频段的信号； 之后， 将上分路和下分路上 的信号汇接于频段合路器后连接于外区子分区； 在频段分路器和频段合路 器之间的上分路上设置可控连接器， 从而通过对可控连接器状态进行切换， 来控制为外区子分区提供的室内分布系统信号频段： 当可控连接器开启时， 外区子分区将接通所有频段的室内分布系统信号源信号； 当可控连接器关 闭时， 外区子分区仅与其它频段的室内分布系统信号相连通。
本发明至少一个实施例可应用于各种移动通信制式， 例如码分多址 /仅 演进数据 （CDMA/EVDO , Code Division Multiple Access/Evolution Data Only )、 通用移动通信系统 ( UMTS , Universal Mobile Telecommunications System) ¾频分默工长期演进 ( FDD-LTE, Frequency Division Duplexing-Long Term Evolution )等。 目前， 移动通信运营商通常同时运营多种网络， 例如， 某运营商经营的公众无线网络主要有三种： 2G/3G 移动通信系统采用 CDMA制式在 800MHz频段， 4G移动通信系统为 LTE在 2.1GHz频段， 还 有无线局域网 （ WLAN， Wireless Local Area Networks )在 2.4GHz频段。 结合图 7所述方案， 正常情况下， 这三种移动通信网络共用室内分布系统， 则室内分布系统信号源包含三种不同移动通信制式的信号， 这三种信号通 过频段合路器合路后通过信号源发送出去； 则除 WLAN仅有室内网络无需 可控连接器控制外， CDMA、 LTE 系统的频段差异较大， 室外网络拓朴也 可能不同， 建议独立控制； 因此， 可将图 7的结构细化为图 8的结构， 其 中， 可控连接器 A控制 LTE信号的连接， 可控连接器 B控制 CDMA信号
的连接。
步骤 102:才艮据室内外信号参数将外区与室内分布系统信号源连通或断 开；
这里， 所述室内外信号参数包括： 室内导频功率，室外最强小区导频功 率、 室内分布系统覆盖边缘场强门限、 仅使用室内分布系统信号的信噪比、 以及仅使用室外信号的信噪比；
具体地， 所述根据室内外信号参数将外区与室内分布系统信号源连通 或断开， 包括：
第一种情况：
当外区子分区当前状态为使用室外信号时， 如果同时满足以下条件 A1 和条件 B 1， 则将外区子分区与室内分布系统信号源连通：
A1、 室内导频功率>室内分布系统覆盖边缘场强门限；
B1、 仅使用室内分布系统信号的信噪比>仅使用室外信号的信噪比 +Y; 其中 Y为迟滞量， Y的取值范围 l-4dB， 目的是避免乒乓切换。
当外区子分区现状为使用室内分布系统信号， 如果同时满足以下条件
A2和条件 B2， 则将外区子分区与室内分布系统信号源断开：
A2、 室外最强小区导频功率>室内分布系统覆盖边缘场强门限；
B2、 仅使用室外信号的信噪比 >仅使用室内分布系统信号的信噪比 +Y; 其中， Y为迟滞量， Y的取值范围 l-4dB， 目的是避免乒乓切换，此时， 外区子分区仅使用室外信号；
另外， 由于室内分布系统的实际应用情况多种多样， 在实际实施中， 并不一定同时以上述 A1和 B 1作为执行断开的判断条件、 以上述 A2和 B2 作为执行连通的判断条件， 还可以仅以上述 A1和 B1作为执行断开的判断 条件， 其余情况下均保持外区与室内分布系统信号源连通； 或者， 以上述 A2和 B2作为执行连通的判断条件， 其余情况下均保持外区与室内分布系
统信号源断开； 因此， 所述根据室内外信号参数将外区与室内分布系统信 号源连通或断开， 还可以包括以下第二、 三种情况：
第二种情况：
当外区当前状态为使用室外信号时，如果同时满足以下条件 A1和条件 B1 , 则将外区与室内分布系统信号源连通：
A1、 室内导频功率>室内分布系统覆盖边缘场强门限；
B1、 仅使用室内分布系统信号的信噪比>仅使用室外信号的信噪比 +Y; 其中， Y为迟滞量， Y的取值范围 l-4dB， 目的是避免乒乓切换。
其余情况下均保持外区与室内分布系统信号源断开。
第三种情况：
当外区现状为使用室内分布系统信号，如果同时满足以下条件 A2和条 件 B2， 则将外区与室内分布系统信号源断开：
A2、 室外最强小区导频功率>室内分布系统覆盖边缘场强门限；
B2、 仅使用室外信号的信噪比 >仅使用室内分布系统信号的信噪比 +Y; 其中， Y为迟滞量， Y的取值范围 l-4dB， 目的是避免乒乓切换，此时， 外区仅使用室外信号；
其余情况下均保持外区与室内分布系统信号源连通。
需要说明的是， Y 的取值并不局限于本发明实施例提供的范围； 在实 际应用中， Y的取值范围往往需要根据网络优化的情况进行调整。
在实际应用中， 可控连接器状态切换判决条件之一的 "室内分布系统 覆盖边缘场强门限" 是室内分布系统设计时的基本覆盖指标， 例如， 对于
FDD-LTE系统， 该参数值通常以下行参考信号接收强度 RSRP进行表征， 所述 RSRP=-105dBm左右； 对于 EVDO 系统， 该参数值通常以接收功率 Rx进行表征， 所述 Rx=-90dBm左右； 切换判决条件之二与信噪比相关的 迟滞参数 Y， 是为了避免可控连接器的乒乓切换， Υ值取值范围为 l~4dB。
步骤 102 中需要艮据室外信号的变化情况， 周期性对可控连接器状态 进行更新， 本发明至少一个实施例提供了下述两种状态更新方法：
第一种是， 人工定期维护控制： 每隔一个周期， 对室内分布系统的外 区进行室内路测， 测试记录每个外区子分区内的室内外信号参数； 然后， 依据上述切换判决条件， 决定各个外区子分区是否开启室内分布系统信号， 最后实施。
第二种是， 自动控制： 在每个外区子分区内， 放置一个或多个分散分 布的自动测量上报终端， 这些终端周期性自动向监控服务器上报室内外信 号参数， 监控服务器依据上述切换判决条件， 对各个可控连接器的状态进 行控制。
