背景技术
在支持多输入多输出(Multiply Input Multiply Out，MIMO)技术的无线通信网络中，如第四代移动通信技术长期演进(Long Term Evolution，LTE)网络中，通常首先是部署单站低阶天线3扇区，如常见的2天线3扇区基站，以满足基本的终端无线服务需求。而随着网络容量(终端数、吞吐量)的提升，通常的扩容手段是扇区分裂为多扇区，例如通过增加射频拉远单元(Radio Remote Unit，RRU)和天线，改为2天线6扇区基站。以LTE技术为例，典型城区的2天线3扇区改为2天线6扇区后，根据仿真预测，网络容量能够提升50％以上。
但是在现有技术中扇区转换或升级过程中，通常都是需要工作人员更换基站的天线，手动升级基站的RRU。这样的扇区转换，转换操作繁琐、转换耗时长，在转换时间内都不能提供通信服务，可能会导致之前位于该基站覆盖范围内的终端不能接入网络；且转换成本高。

具体实施方式
以下结合说明书附图及具体实施例对本发明的技术方案做进一步的详细阐述，应当理解，以下所说明的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
实施例一：
如图1所示，本实施例提供一种扇区转换方法，包括：
步骤S110：检测指定信息；其中，所述指定信息用于反映扇区转换需求；
步骤S120：将所述指定信息发送给控制网元；
步骤S130：接收所述控制网元在所述指定信息满足第一预设条件时，返回的转换指令；
步骤S140：响应所述转换指令，通过调整可调天线及射频拉远单元的工作参数实现扇区转换。
本实施例所述扇区转换方法可为应用于基站中的扇区转换方法。这里的扇区又可称为扇区，是蜂窝通信网络中提供通信服务的基本单位。
所述扇区转换可包括：根据扩容需求，进行扇区升级等。例如，可以根据网络容量以及网络中高阶MIMO能力的终端比例，进行2天线3扇区升级为2天线6扇区，再由2天线6扇区升级为4天线3扇区的升级演进。这里的高阶MIMO能力为采用指定阶数以上的MIMO技术的能力。
所述步骤S110中基站将会检测指定信息，这里的指定信息可用于控制网元判断是否需要进行本基站的扇区转换。在本实施例中所述控制网元可为用于维护网络设备的操作管理中心(Operation and Maintenance Center，OMC)或自组织网络(Self-Organized Network，SON)的管理中心服务器等能够对基站进行维护控制的管理网元。
在步骤S130中将接收控制网元返回的转换指令。所述转换指令至少包括用于指示是否需要执行转换的操作指令，以及进行转换的各种转换参数。所述转换指令可包括如何重新配置可调天线及RRU的工作参数，所述转换参数可包括转换后的可调天线和RRU的工作参数等信息。当然值得注意的是，所述控制网元，将在根据所述指定信息判断出当前基站确实需要进行扇区的转换时，通过转换指令指示基站进行扇区切换。所述RRU是在远端 将基带光信号转成射频信号放大传送出去。通常，RRU可分为四个功能模块：中频模块、收发信机模块、功放和滤波模块。数字中频模块用于光传输的调制解调、数字上下变频、A/D转换等；收发信机模块完成中频信号到射频信号的变换；再经过功放和滤波模块，将射频信号通过天线口发射出去。通过改变所述RRU的工作参数，可以调整所述RRU的信号放大倍数等工作参数，从而改变本基站发送的无线信号的辐射范围等。
在本实施例中步骤S140中，将响应切换指令，调整可调天线和RRU的工作参数，就能够实现扇区的转换。在本实施例中所述可调天线为通过软件改写其工作参数，就能够使其为新扇区收发信号的天线。具体如，可以通过调整工作参数，调整收发信号的天线数目、调整天线的俯仰角、方位角、总发射功率及单个信道的发射功率等信息。本实施例中的所述可调天线可为可调的劈裂天线。完成了可调天线和RRU的工作参数的调整，就相当于重新划分了基站覆盖的扇区，从而实现了扇区的调整。
总之，本实施例提供了一种扇区转换方法，能够无需工作人员到基站所在地更换天线，调整天线和RRU的工作参数的情况下，就能够通过与控制网元的信息交互，实现扇区的自动转换，具有转换效率高及转换成本低等多重优点。
所述指定信息可包括终端的能力参数、基站的负荷状况信息以及基站所在位置的网络部署信息其中的一个或多个。具体地如，所述步骤S110可包括：检测具有预设终端能力的终端比例、网络部署信息、负荷状况信息及检测邻区干扰信息的至少其中之一；其中，所述终端比例是根据终端的能力参数统计确定的；所述网络部署信息用于反映本基站所在位置的网络部署状况；所述负荷状况信息用于反映所述本基站的负荷状况；所述邻区干扰信息用于反映邻小区的干扰强度。本实施例中所述本基站可为本实施例扇区转换方法的执行基站；或需要进行扇区转换的基站。
所述控制网元可以根据上述信息中的一个或多个，判断是否服务第一预设条件；通常若符合第一预设条件，则认为本基站有扇区切换需求，若不符合第一预设条件，则认为本基站没有扇区切换需求。具体的实现方式有多种，以下提供几种可选方式：
可选方式一：
所述步骤S110可包括：检测终端的能力参数；根据所述能力参数，统计当前扇区内具有预设终端能力的终端比例；所述步骤S120可包括：将所述终端比例发送给所述控制网元；所述步骤S130可包括：接收所述控制网元在所述终端比例大于比例阈值时，发送的转换指令。例如，若本基站当前形成的扇区为低阶的MIMO扇区，而通过接收终端发送的能力参数，确定出经常驻留在本基站形成的扇区内的支持高阶MIMO能力的终端的比例很高，为了提供更好的通信服务，则确定本基站有升级到更高阶的MIMO扇区的需求。则所述基站将接收到转换指令。在本实施例中接收到指示基站执行转换的指令，为支持预设类型扇区的比例达到比例阈值之后发送的，显然使得基站的扇区转换满足了实际需求，而非盲目转换。
可选方式二：
所述步骤S110可包括：检测网络部署信息；所述步骤S120可包括：将所述网络部署信息发送给所述控制网元；所述步骤S130可包括：接收所述控制网元在所述网络部署信息表明需要调整本基站的覆盖参数时，发送的转换指令。
在本实施例中会将网络部署信息发送给控制网元。这里的网络部署信息为本基站附近的网络部署信息，例如，距离本基站指定距离内的网络部署信息，或与本基站相邻的相邻基站的部署信息。这里的网络部署信息可包括基站新增信息、基站删减信息、或相邻基站的覆盖范围变化信息、相邻基站的信号功率信息等。网络部署可决定无线环境是否适宜，可决定本 基站的通信环境。例如，检测到新增相邻基站，若本基站不调整覆盖范围，就可能会导致在交叠区域出现相互干扰，导致通信质量差；则此时，可能需要调整本基站的覆盖范围。在本实施例中所述覆盖参数可包括覆盖范围、无线信号发射功率以及本基站覆盖范围内每一个位置的无线信号的频率等信息。
这样，就实现了本基站在需要调整覆盖参数时，自适应的调整覆盖参数，以实现扇区的转换。
可选方式三：
所述步骤S110可包括：检测本基站的负荷状况信息；所述步骤S120可包括：将所述负荷状况信息发送给所述控制网元；所述步骤S130可包括：接收所述控制网元在所述负荷状况信息表明所述本基站的网络负荷大于第一预定门限时，发送的转换指令。
在本实施例中若本基站在第一预定时间间隔内的负荷状况信息，若本基站经常处于较高的负荷比例，这样可能会导致通信质量差及通信带宽小等问题，显然本基站有扩容的需求。此时，可以通过扇区的转换来实现扩容。故在本实施例中可检测所述负荷状况信息，将负荷状况信息传输到控制网元。
可选方式四：
所述步骤S110可包括：检测邻区干扰信息；所述步骤S120可包括：将所述邻区干扰信息发送给所述控制网元；所述步骤S130可包括：接收所述控制网元在所述邻区干扰信息表明邻小区的干扰强度大于预定干扰门限时，发送的转换指令。
若基站的覆盖范围过大，即扇区覆盖范围过大，就可能会导致邻区之间的相互干扰增强，在本实施例中还包括检测邻区干扰信息，例如，检测邻区干扰强度，这里的邻区可理解为邻小区。本发明实施例中小区是与扇 区相对应的。将邻区干扰信息发送给控制网元，控制网元接收到对应的信息之后，就会判断是否出现较强的邻区干扰，例如，通过与所述预定干扰门限比对，确定出是否有较强的邻区干扰。若有较强的邻区干扰，就存在扇区转换需求，就需要进行扇区转换，故所述基站将会接收到对应的转换指令，通过扇区转换减小邻区干扰。
以上提供了四种指定信息及对应的第一预设条件，上述三种可选方式可以任意结合使用。
可选地，在所述响应所述转换指令，通过调整可调天线及射频拉远单元的工作参数实现扇区转换之前，所述方法还包括：
将驻留在本基站小区内的终端切换到邻小区；
向邻小区发送第一更新通知；其中，所述第一更新通知用于通知所述邻小区已删除所述本基站形成的旧小区。
在进行扇区转换时，为了保持驻留在本基站形成的旧小区中的终端的通信持续性，在进行转换之前需要将这些终端切换到邻小区。由于进行扇区转换，相当于会删除旧小区，为了确保邻小区的邻区关系正确，在本实施例中在删除旧小区之前，还会形成第一更新通知，该通知将告知本基站的邻小区进行邻区关系更新。
可选地，在所述响应所述转换指令，通过调整可调天线及射频拉远单元的工作参数实现扇区转换之后，所述方法还包括：
根据可调天线及射频拉远单元的工作参数，配置新小区；
基于所述新小区的信息，形成第二更新通知；
向所述邻小区发送第二更新通知，其中，所述第二更新通知用于通知所述邻小区调整邻区关系。
在完成可调天线和RRU的工作参数调整之后，本基站将自动配置新小区，新小区配置之后，为了确保本基站的邻小区的邻区关系正确，会向邻 小区发送第二更新通知，方便邻小区将新配置的新小区添加到邻小区列表中。所述邻区关系至少用于反映与一个小区相邻的小区有哪些。
可选地，为了尽可能的缩小扇区切换导致的终端通信中断和邻扇区的通信拥堵，在本实施例中当接收所述控制网元在所述指定信息满足第一预设条件时，返回的转换指令之后，所述方法还包括：选择满足第二预设条件的转换时机；所述步骤S140可包括：在所述转换时机，执行所述转换指令以调整所述天线及所述射频拉远单元的工作参数。在本实施例中所述满足第二预设条件的转换时机可为转换时负面影响在预设程度内的时机。显然在本实施例中进行扇区转换时，不是随机的，这样可以避免由于基站扇区的转换，导致的大量终端通信中断的问题。具体地如，所述选择满足第二预设条件的转换时机，包括：选择本基站的网络负荷小于第二预定门限的时间段，作为所述转换时机。根据本基站的网络负荷来确定，在本实施例中网络负荷小于第二预定门限的时间段，这样需要切换到邻扇区的终端数少，导致的终端通信中断的情况少，且能够避免邻扇区的过分拥堵。
当然在具体的实现过程中，选择满足所述第二预设条件的转换时机，还可包括：选择相邻基站不进行扇区转换，和/或，相邻基站的网络负荷低于第三预定门限的时间段，以尽可能的缩小扇区转换过程中的不利影响。例如，本基站可以通过与相邻基站之间的信息交互，知晓相邻基站是否需要进行扇区转换，预定何时进行扇区转换，相邻基站当前的网络负荷状况等。本基站可以通过与相邻基站之间的信息协商，确定出满足所述第二预设条件的转换时机。
值得注意的是：本实施例中的扇区与小区具有对应关系，例如，扇区的面积缩小，可能导致对应小区的面积缩小。
所述步骤S140可包括：
执行所述转换指令，通过调节所述可调天线中馈电网络内部的连接关 系，调整所述可调天线的波束特性。
例如，本实施例中所述可调天线可为远端可电调控制的n端口劈裂天线。如图2所示，所述可调天线可包括m个天线振子。天线振子通过馈电网络与天线端口连接。其中，所述m大于所述n。所述n的取值通常为偶数，例如，2、4、6或8等。所述馈电网络可包括多个功分器和调相器。在图2中还显示有AISG接口控制线。所述AISG为antenna interface standards group的缩写，对应的中文为天线接口标准组。
示例一，在本实施例中可通过调节功分器和调相器之前的连接关系，实现馈电网络内部的连接关系的调整。
示例二，馈电网络可包括两个连接子网络，可以通过连接子网络的切换，实现与天线振子连接的馈电网络的变化，从而实现天线的波束特性的调整。
示例三：馈电网络可包括两个连接子网络，这两个馈电子网络又通过功分器和调相器连接，通过改变与这两个连接子网络通过共用或不共用这凶恶功分器和调相器，实现馈电网络内部的连接关系的调整，从而调整天线的波束特性。
通常波束特性决定了天线的覆盖区域、覆盖范围等各种参数，从而能够用于扇区的转换。
例如，智能馈电网络通过标准的AISG接口和外部控制设备相连接，其内部有A和B两种馈电网络组合方式，在A馈电网络方式下天线水平方向图为33°的双波束，在B馈电网络方式下天线水平方向图为65°的单波束。基站通过远端电调命令控制A和B馈电方式的变化实现天线放线图的分裂与合成，从而完成扇区转换。图3A为双波束的方向图；图3B为单波束的方向图。
实施例二：

其中，所述转换指令用于供所述基站执行可调天线及射频拉远单元的工作参数，以实现扇区转换。

在一些实施例中所述步骤S220包括以下至少之一：

判断所述网络部署信息是否表明需要调整本基站的覆盖参数；
判断所述负荷状况信息是否表明对应基站的网络负荷大于第一预定门限；

本示例提供从水平六扇区2T2R到三扇区4T4R的转换。
在网络中，基站下行配置12个发射通道，上行配置了12个收通道。具体的设备形式是水平六扇区2T2R的网络拓扑。拓扑结构如图10所示。图10中每条短线表示一个扇区天线的方位角，其基站配置为2T2R。随着支持4R终端(4R终端为具有4根接收天线的终端)比例不断上升，达到一定比例后，可以启动进程，转变为三扇区4T4R的网络，拓扑结构如图11所示。从而支持更高的系统容量。具体的转变步骤如下：
基站统计现网中4R终端能力，并上报OMC或者SON服务器；
当基站中4R能力终端比例超过某门限时，OMC或SON服务器根据事先配置实现基于人工指令的或者自动地发送调整命令给相应基站，同时将变更为4T4R扇区后的相应无线参数也发送给基站；
基站收到调整命令以及无线参数后，首先将剩余终端切换到同覆盖邻扇区，然后关闭扇区；
关闭扇区后，基站通过远端电调命令，将劈裂天线调整为4T4R单扇区天线；同时，将原来一副劈裂天线对应的2个2T2R天线RRU并柜配置为一个4T4R射频单元；

示例六：
为了收缩覆盖以降低干扰，本示例提供一种触发六扇区2T2R转变为三扇区4T4R的扇区转换方法。
在网络中，基站下行配置12个发射通道，上行配置了12个收通道。具体的设备形式是六扇区2T2R的网络拓扑。六扇区的天线宽度(水平半功率角)较窄，天线增益较大，扇区的覆盖半径较大。拓扑结构如图10所示。基站配置为2T2R。随着网络建设不断进行，站点数量不断增加，站间距不断减小，相邻站间干扰不断增大。当邻扇区干扰达到一定比例后，可以启动进程，转变为三扇区4T4R的网络，拓扑结构如图11所示。三扇区天线的宽度增加，天线增益减小，覆盖收缩从会降低邻扇区间的干扰。具体的转变步骤如下：
基站统计现网中上行噪声抬升(IoT)，并上报OMC或者SON服务器。
当基站中长期统计IoT超过某门限时，OMC或SON服务器根据事先配置实现人工地或者自动地发送调整命令给相应基站，同时将变更为三扇区后的相应无线参数也发送给基站。
基站收到调整命令以及无线参数后，首先将剩余终端切换到同覆盖邻小区，然后关闭小区。
关闭小区后，基站通过远端电调命令，将劈裂天线调整为三扇区天线；同时，将原来一副劈裂天线对应的2个2T2R天线RRU并柜配置为一个4T4R射频单元。
天线和射频单元调整完毕后，基站重新建立和激活小区，并按照OMC或SON服务器配置的无线参数配置新小区，特别是调整天线的电子倾角，控制覆盖。
该基站重配置完成后，周围邻小区的无线参数也可能做相应更改。
