Description

一种实现 2G网络电调天线集中控制的方法、 系统及设备 本申请要求于 2006 年 8 月 8 日提交中国专利局、 申请号为 200610109549.X, 发明名称为"一种实现 2G 网络电调天线集中控制的方法及 系统"的中国专利申请的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信领域, 特别是涉及一种实现 2G网络电调天线集中控制的 方法、 系统及设备。
背景技术
移动通信天线的技术发展很快,最初主要使用普通的定向和全向型移动天 线, 现在一些移动网已经开始使用电调天线。 所谓电调天线, 即指使用电子调 改变垂直分量和水平分量的幅值大小, 改变合成分量场强强度,从而使天线的 垂直方向性图下倾。 由于天线各方向的场强强度同时增大和减小,保证在改变 倾角后天线方向图变化不大,使主瓣方向覆盖距离缩短, 同时又使整个方向性 图在服务小区扇区内减小覆盖面积但又不产生干扰。
实践证明, 电调天线下倾角度在 1°-5°变化时, 其天线方向图与机械天线 的大致相同; 当下倾角度在 5。-10。变化时, 其天线方向图较机械天线的稍有改 善; 当下倾角度在 10。-15。变化时, 其天线方向图较机械天线的变化较大; 当 电调天线下倾 15°后, 其天线方向图较机械天线的明显不同, 这时电调天线方 向图形状改变不大, 主瓣方向覆盖距离明显缩短, 整个天线方向图都在本基站 扇区内, 增加下倾角度, 可以使扇区覆盖面积缩小, 但不产生干扰, 这样的方 向图是我们需要的, 因此釆用电调天线能够降低呼损, 减小干扰。 而且釆用电 调天线可以大幅度降低天线下倾角的运营维护成本,提高工作效率。 因此随着 电调天线相关技术的成熟与 3G网络的建设, 运营商越来越倾向于使用电调天 线。
目前已有将 2G网络中普通天线设备更换为电调天线设备,或者在新增 2G 网络中釆用电调天线。对釆用电调天线后的控制问题目前也有解决的方法,现 有技术主要釆用将电调天线设备用 2G基站设备进行控制。
由于 2G基站设备已经比较成熟稳定, 而电调天线设备为一种新型设备, 2G基站设备对电调天线设备的控制, 目前可以釆取两种方法:
1、 开发电调天线功能集成到操作维护中心 (OMC ) 中并对现网的 2G设 备进行升级。 这样需要增加 2G软件的开发投入, 并且原有硬件不支持天线接 口标准集团 (AISG )协议的通讯方式, 会造成硬件的修改。 由于软硬件的修 改, 会对产品的稳定性造成一定的冲击, 并且硬件升级是釆用更换单板形式, 成本较高。
2、 釆用电调设备的单独维护终端进行控制。 具体系统参见图一, 用户将 控制命令通过单独维护终端发送到电调天线的控制电调动作单元 RCU, 不通 过原有 2G设备进行控制。由于电调天线设备是和基站 NodeB中的扇区存在一 一对应关系的, 如果天线设备和 NodeB分开维护, 就需要用户来维护这种对 应关系, 造成了维护的复杂性大大提高。 并且如果同时用户建设 3G网络, 由 于 NodeB已经支持统一维护 3G的电调设备, 3G设备是能够直接控制电调天 线的, 这样就会形成 2G网络釆用单独的维护终端, 3G网络直接用 3G设备控 制电调天线,造成维护方式的不同带来成本提高。 若单独维护终端为用户自行 购买, 将进一步提高用户的成本。
综上所述, 现有技术虽然能够解决对已有 2G网络中普通天线设备更换为 电调天线设备, 或者新增 2G网络中釆用电调天线后的控制, 但是存在升级风 险大、 成本高, 维护复杂及维护成本高等问题。
发明内容
本发明实施例在于提供实现 2G网络电调天线集中控制的方法、 系统及设 备, 运用该系统及方法能够实现方便用户操作、 维护成本低的 2G网络电调天 线的集中控制。
本发明实施例的技术方案包括:
一种实现 2G 网络电调天线集中控制的方法, 该方法包括:
接收需要控制的 2G 网络电调天线的标识及控制命令;
才艮据所述标识查找对应的 2G 网络电调天线;
3G基站设备向所述 2G网络的电调天线发出控制命令, 控制 2G 网络的 电调天线。
一种实现 2G 网络电调天线集中控制的系统, 该系统包括: 控制平台和 3G基站设备, 其中:
所述控制平台, 用于接收并向 3G基站发送需要控制的 2G 网络电调天线 的标识及控制动作;
所述 3G基站设备, 用于接收控制平台发送的所述电调天线的标识及控制 动作, 通过所述标识查找对应 2G 网络的电调天线, 向所述电调天线设备发出 控制命令, 控制 2G 网络的电调天线。
一种 3G基站设备, 包括:
存储单元, 用于保存 2G网络电调天线标识;
控制单元, 用于向所述 2G网络电调天线标识对应的 2G网络的电调天线 发出控制命令。
由于 2G网络和 3G网络都分配有不同的频段, 不存在干扰, 因此不同网 络的电调天线可以釆用较近距离安装,由于不同网络中的调制解调器的作用并 没有差别, 因此可以釆用单个调制解调器来对信号进行解调。本发明实施例釆 用 3G基站集中控制 2G网络的电调天线的方式, 不需对 2G基站设备进行升 级, 避免了升级风险、 降低了升级成本; 由于不需用户单独维护基站扇区同电 调天线的对应关系所以大大降低了维护成本; 且方便了用户操作。

具体实施方式
本发明实施例提供了一种实现 2G网络电调天线集中控制的方法, 该方法 通过 3G基站集中控制 2G网络的电调天线。 因为 2G网络和 3G网络都分配有 不同的频段, 不存在干扰, 因此不同网络的电调天线可以釆用较近距离安装, 釆用单个调制解调器 (SBT )对控制信号进行解调。 各个天线在链路层釆用 AISG 中规定的高级数据链路控制 (HDLC )地址标识, 并釆用全球唯一的序 列号进行区分。由于 2G网络和 3G网络中的电调天线和调制解调器都无差别, 只要通过设置软件, 就可用 3G基站来完成控制 2G网络中的电调天线。
具体实施例一釆用查找电调天线设备全球唯一序列号实现, 参见图 2: 步骤 110: 用户向控制平台输入需要控制的 2G天线设备序列号及控制动 作; 由控制平台将需要控制的 2G电调天线序列号及控制动作传递至 3G基站 设备;
步骤 120: 3G基站设备查找该 2G电调天线设备序列号, 若查找成功则执 行步骤 130, 若查找不成功则结束该流程;
步骤 130: 3G基站设备判断控制链路是否正常, 若是则执行步骤 140, 若 否则结束该流程;
判断控制链路是否正常的过程主要为 3G基站设备向电调天线设备发送 HDLC协议中的接收就绪( RR )帧,并且定义发送 RR帧的超时时间为 100ms, 如果发送 RR帧超过五次超时, 那么就判断该链路是不正常的。
当然这个判断控制链路是否正常的过程也可以釆用其他方法,比如超时时 间为 70ms, 超过 3次为链路不正常等。
步骤 140: 3G基站设备向电调天线设备发出模拟信号控制命令; 步骤 150: 将该模拟信号控制命令调制成数字信号发送至电调天线; 步骤 160: 电调天线执行控制命令进行倾角调整;
步骤 170: 电调天线执行完控制命令后, 将操作成功或失败信息解调成模 拟信号后通过 3G基站设备向控制平台发送该信息。
该方法中, 为解决 3G网络中并没有 2G网络的相关信息, 无法按照 3G 网络中的站点、 小区的方式或物理位置进行标识的问题, 需要在安装电调天线 为了用户便于记忆及操作更加方便,可以釆用让用户自己创建电调天线设 备名称的方式进行管理。
具体实施例二为通过用户设置电调天线名称来对应电调天线设备全球唯 一序列号实现, 参见图 3:
步骤 210:用户输入需要控制的 2G电调天线名称及控制动作到控制平台; 由控制平台将需要控制的 2G电调天线名称及控制动作传递至 3G基站设备; 步骤 220: 3G基站设备查找名称对应的 2G电调天线设备序列号, 查找成 功则执行步骤 230, 若不成功则结束该控制流程;
步骤 230: 3G基站设备判断控制链路是否正常, 若正常则执行步骤 240, 若不成功则结束该控制流程;
该控制链路判断过程与实施例一相同, 在此不再累述;
步骤 240: 3G基站设备向电调天线发出模拟信号控制命令;
步骤 250: 将该模拟信号控制命令调制成数字信号发送至电调天线; 步骤 260: 电调天线执行控制命令进行倾角调整;
步骤 270: 电调天线执行完控制命令后, 将操作成功或失败信息解调成模 拟信号后通过 3G基站设备向控制平台发送该信息。
该方法步骤 210中所述的用户输入需要控制的 2G电调天线名称的命名方 式为:
站点—扇区 +天线口 +射频子扇区编号 +设备类型―网络类型
其中:
站点: 同"增加站点"所用站点编号;
扇区: 同"扇区编号"所用扇区编号;
天线口: 天线连接到基站的端口编号;
射频子扇区编号: 扇区分裂情况下, 对于每一个射频子扇区的编号, 如果没有扇区分裂此处固定添 0;
设备类型: 区分当前连接设备是塔顶放大器( TMA )还是远端电角度 ( RET, Remote Electrical Tilt )单元;
网络类型:当前为 2G网络, 还是 3G网络。
例如: 0号站点; 0号扇区; A口连接; 0号射频子扇区; RET; 2G 标识为 :0— 0A0RET— 2G
3G 网络中可釆用将天线名称和具体的天线序列号进行绑定, 以达到 维护具体天线的目的。 例如: 一个 2G网络中的电调天线, 供应商为 KA, 设备序列号为 012345678901234。 对应关系可如下:
天线设备名称 供应商编码 设备序列号 设备类型
0 0A0RET 2G KA 012345678901234 RET 该方法中所述的电调天线命名规则不限于上述形式,只要是能够便于用户 操作并且可唯一标识电调天线的方式即可。
该方法中, 为解决 3G网络中并没有 2G网络的相关信息, 无法按照 3G 网络中的站点、 小区的方式或物理位置进行标识的问题, 需要在安装电调天线 由 3G基站按照对应关系扫描电调设备序列号进行与 2G电调天线的匹配。
具体实施例三为通过用户设置电调天线名称来对应电调天线设备全球唯 一序列号实现, 与实施例二不同的是将对应关系保存在控制平台, 参见图 4: 步骤 310:用户输入需要控制的 2G电调天线名称及控制动作到控制平台; 步骤 320: 控制平台查找 2G天线设备序列号, 查找成功则执行步骤 330, 若不成功则结束本流程;
步骤 330: 控制平台将查找到的 2G天线设备序列号发送至 3G基站设备; 步骤 340: 3G基站设备判断控制链路是否正常, 若是则执行步骤 350 , 若 否则结束本流程;
该控制链路判断过程与实施例一相同, 在此不再累述;
步骤 350: 3G基站设备向电调天线发出模拟信号控制命令;
步骤 360: 将该模拟信号控制命令调制成数字信号发送至电调天线; 步骤 370: 电调天线执行控制命令进行倾角调整;
步骤 380: 电调天线执行完控制命令后, 将操作成功或失败信息解调成模 拟信号后通过 3G基站设备向控制平台发送该信息。
该方法中所述电调天线名称的命名规则同实施例二中的方法。
该方法中为解决 3G网络中并没有 2G网络的相关信息, 无法按照 3G网 络中的站点、 小区的方式或物理位置进行标识的问题, 需要在安装电调天线时 平台根据预设对应关系查找出电调天线设备序列号发送 3G基站, 3G基站需 存储 2G网络电调天线设备序列号来与 2G网络电调天线匹配。
以上 3个实施例中所述的调制解调过程可以放置于 3G基站设备或电调天 线设备中进行, 也可以在单独的调制解调设备中进行, 或者调制过程在 3G基 站设备中进行, 解调过程在电调天线设备中进行。 本发明实施例还提供了一种实现 2G网络电调天线集中控制的系统, 该系 统用于实现便于用户操作、 维护成本低的 2G网络电调天线集中控制方法。 该 系统中所有的电调天线的控制电调动作单元都用 AISG控制信号线通过调制解 调器与 3G基站相连接, 由于 2G网络和 3G网络中的电调天线和调制解调器 都无差别, 只要通过设置软件, 用 3G基站来控制 2G网络中的电调天线。
参见图 5, 该系统包括控制平台、 3G基站设备、 电调天线设备和调制解 调模块。 其中, 控制平台相当于人机接口, 是运行在服务器中的软件, 图 5 中未示出。

线集中控制, 并将电调天线设备名称与序列号的对应关系保存于控制平台时: 控制平台主要用于存储 2G电调天线名称与设备序列号对应关系, 接收用 户输入的需要控制的 2G天线设备名称及控制动作, 根据存储的对应关系查找 接收到的天线设备名称所对应的设备序列号, 向 3G基站发出需要控制的 2G 天线设备序列号, 接收电调天线经 3G基站反馈的执行结果信号;
3G基站主要用于接收控制平台发送的天线设备序列号及控制动作, 判断 控制链路是否正常, 向电调天线设备发出模拟信号控制命令,接收电调天线返 回的执行结果信号, 并将该信号传递至控制平台;

在上述实现 2G网络电调天线集中控制系统的三个实施例中,如图 5所示, 所有电调天线都釆用级连的方式进行连接, 但在实现过程中并不排除每个 2G 网络中的电调天线都通过 AISG控制信号线连接到一个调制解调设备的并联的 方式, 这个调制解调器与 3G设备相连接, 控制命令统一由 3G设备发出; 每 个 2G电调天线又与 2G设备通过射频信号线相连,所有的射频信号仍然在 2G 电调天线与 2G设备间传送, 参见图 6。
上述所有实施例中, 包括方法实施例和系统实施例, 3G基站设备向电调 天线设备发出的是模拟信号控制命令, 该控制命令经调制解调后, 到达待调控 的 2G电调天线,相应的 2G电调天线反馈的执行结果信号经调制解调到达 3G 基站设备。对上述信号的调制解调的过程可以参考现有技术中各种模拟信号与 数字信号之间的调制解调方法, 其具体实现过程并不构成对于本发明的限制。 同时, 可以理解的是, 上述仅为具体的实施方式, 在实际应用中上述信号控制 命令及执行结果信号也可以直接以数字信号的形式发送,从而可以省略调制解 调操作, 相应的系统中也可以不需要调制解调模块。
由于图 5仅是一实施例, 因此, 对于一种实现 2G网络电调天线集中控制 的系统可以仅包括控制平台和 3G基站设备。
