Description

小区切换方法及系统 技术领域
本文涉及移动通信领域，尤其是一种在高电平质差情况下的小区切换方法及系统。
背景技术
移动通信系统中切换技术是保证用户在移动过程中获得高质量网络服务的一项关键技术。
在通话过程中，当用户在服务小区处于高干扰环境中或者受到时隙级突发干扰时，用户在服务小区的上下行接收电平正常但是接收质量较差。相关技术的切换算法中，以邻区电平大于等于服务小区电平为切换条件，当服务小区满足了质量切换的条件进行邻区筛选时，如果邻区信号没有服务小区强时，会存在无法及时切出持续通话质量较差小区或者掉话的问题，例如：
假设邻区质量切换门限为正，即切换判决时邻区必须满足比服务小区电平强的条件，如果邻区比服务小区电平弱，则无法及时发生切换；
假设邻区质量切换门限为负(在当前网络中这种设置并不常见)，即切换判决时邻区可以比服务小区电平弱。但是相关技术的质量切换触发判断时并没有对服务小区的电平进行判断，假设服务小区的电平为-100dBm，再判决往电平更弱的小区切换，则很有可能切换失败或者切到了一个更差的小区，也就是说，按照这种设置并不适合弱电平质差的场景。
虽然开启小区内切换有可能对时隙级的突发干扰有所改善，但是目前跳频技术的普遍应用导致关闭了小区内切换，因此也不能依靠小区内切换来解决高电平质差(即电平较高但通话质量较差)切换的问题。
综上所述，在通话过程中，若无线链路处于高电平质差的状态，邻区信号没有服务小区强时，相关技术的切换算法无法保证用户及时切换到较好的小区，用户会一直处于服务小区较差的无线环境下，直至掉话。

附图概述
图1为本发明一实施例中小区切换方法的流程示意图；

图3为本发明另一实施例中小区切换系统的结构示意图；
图4为本发明又一实施例中小区切换系统的结构示意图。
本发明的实施方式
下面结合附图对本发明的实施方式进行说明。
本文提供一种小区切换方法，参照图1，本发明一实施例中，该小区切换方法至少包括以下步骤：
步骤S10，无线操作维护中心根据小区的通信条件配置与服务小区的电平存在映射关系的、发生切换时服务小区可以容忍的邻区比服务小区低的电平偏置数，并将所述电平偏置数同步到基站控制器；本发明实施例中，无线操作维护中心根据每个小区的通信条件的不同，设定不同的邻区电平偏置数。邻区电平偏置数即表示服务小区如果要发生切换可以容忍的邻区比服务 小区低的电平dB数，其为正值，与服务小区的电平存在映射关系。本实施例中，在无线操作维护中心新增的配置参数可包括高电平质差切换开关GoodLevBadRQHoEnable和邻区电平偏置GoodLevBadRQoffSet[N]，N表示为多个数值。当服务小区电平高时，容忍的偏置值高，服务小区电平低时，容忍的偏置值低，以避免切换到信号更差的小区。如下为GoodLevBadRQoffSet[5]的举例说明：
RxLev(dBm) GoodLevBadRQoffSet 默认取值
>＝-60 [0,63] 20
-60～-70 [0,63] 15
-70～-75 [0,63] 10
-75～-85 [0,63] 5
<-85 [0,63] 0
上述配置参数配置好后，同步下发到基站控制器BSC。
步骤S20，基站控制器获取服务小区以及邻区下行的电平值，根据服务小区下行的电平值选择对应的电平偏置数；基站控制器根据小区测量报告得到服务小区和邻区的一系列电平平均值之后，就可以进行切换判决了。在上/下行质量切换成立后，当原有切换流程判决得到的目标小区个数为0时，判断系统是否支持高电平质差切换功能。若支持，转入步骤S30。当原有流程得到的目标小区个数不为0时，即按原有的切换流程进行判决，如果存在可以切换的小区，则说明存在信号相对较好的邻区，可以选择这些小区进行切换，不必执行本发明实施例的流程。
步骤S30，判断邻区下行的电平值与电平偏置数的和是否大于等于服务小区下行的电平值与功率补偿的和；
步骤S40，若是，则筛选满足该条件的邻区进行切换。根据本服务小区下行平均电平所对应的区间，选择设置的GoodLevBadRQoffSet[5]中对应的偏移数值，判断(邻区下行平均电平+GoodLevBadRQoffSet)是否大于等于(本小区下行平均电平+功率补偿)，功率补偿为：基站的发射功率等级BSPower*2。例如，基站控制器获取服务小区的接收信号电平平均值 RxLev(dBm)为-60，该数值所对应的偏置区间GoodLevBadRQoffSet为0-63，默认偏移值为20，则将邻区下行平均电平进行补偿运算，在实际平均值上加上默认偏移值20，并判断运算结果是否大于等于服务小区的接收信号电平平均值-60与功率补偿的和，功率补偿为基站的发射功率等级BSPower乘以2。若是，则判定邻区为满足切换条件的小区，可以选择这些小区进行切换。若否，则不进行切换，继续收集测量报告判断邻区是否满足条件。
本发明实施例中，通过无线操作维护中心根据服务小区通信条件的不同，设定不同的邻区电平偏置数，该电平偏置数为正值。基站控制器获取到服务小区和邻区的电平值时，将邻区电平值与该电平偏置数相加，得到大于邻区实际电平值的数值，再判断该数值是否大于等于服务小区的接收信号电平平均值-60与功率补偿的和，即以该运算值作为判断依据判断邻区电平是否高于服务小区电平，若是，则选择该邻区进行切换。本发明实施例当存在高电平质差情况时服务小区切换可以切换到电平相对较弱的邻小区，避免切入质量更差的小区，保证了切换的准确性。因此，采用本发明实施例的方法可以降低掉话率指标，改善用户感知度，提升运营商竞争力。
本发明一实施例中，上述步骤S10中包括：
无线操作维护中心配置高电平质差切换开关、邻区电平偏置数，并将所述高电平质差切换开关和邻区电平偏置数同步到基站控制器。切换开关的设定，可以供用户选择是否进入本发明实施例的切换流程，例如，若切换开关为开启状态，则说明系统支持本发明实施例的切换流程。本发明实施例中，在执行上述步骤S30之前，上方法流程还可包括判断高电平质差切换开关是否开启的步骤，若是，则执行步骤S30。
参照图2所示，本发明另一实施例中，上述步骤S20之前还包括：
步骤S200，以邻区电平大于等于服务小区电平为切换条件执行切换流程；即按原有的切换流程进行切换，如果存在可以切换的小区，则说明存在信号相对较好的邻区，可以选择这些小区进行切换，不必执行本发明实施例的流程。
步骤S201，判断可进行切换的邻区数是否为0，若是，则执行判断高电平质差切换开关是否开启的步骤。当按原有流程进行切换时，若判决可进行 切换的邻区数是否为0，则说明邻区的信号均弱于服务小区，此时，执行本发明实施例的切换流程，首先判断高电平质差切换开关是否开启，若是，则执行步骤S20。
本发明又一实施例中，上述步骤S10中还可包括：
无线操作维护中心配置高电平质差切换开关、邻区电平偏置数和服务小区需满足的电平门限，并将所述高电平质差切换开关、邻区电平偏置数和服务小区需满足的电平门限同步到基站控制器。
本实施例在前述实施例的基础上增加本小区需满足的电平门限参数，避免人工设置GoodLevBadRQoffset参数不合理，在服务小区电平低时切入了无线质量更差的小区。该参数与GoodLevBadRQoffset配合使用控制切换效果更好，默认值为30，表示-80dBm。本发明实施例中，在执行判断高电平质差切换开关是否开启的步骤之后包括：判断服务小区下行的电平值是否大于服务小区需满足的电平门限，若是，则执行步骤S30。
前述实施例中，还可包括对满足条件的小区进行排序，按序选择邻区进行切换的步骤，以进一步保障通话质量。
本发明实施例还提供一种小区切换系统，用于实现上述方法。参见图3，本发明一实施例中，该小区切换系统包括无线操作维护中心10和基站控制器20，其中：
无线操作维护中心10包括配置模块11，设置为：配置与服务小区的电平存在映射关系的邻区电平偏置数，并将所述电平偏置数同步到基站控制器；本发明实施例中，邻区所需满足的电平偏置即表示服务小区如果要发生切换可以容忍的邻区比服务小区低的电平dB数，与服务小区的电平存在映射关系。通过配置模块11在无线操作维护中心10新增配置参数，包括高电平质差切换开关GoodLevBadRQHoEnable和邻区所需满足的电平偏置GoodLevBadRQoffSet[N]，N表示为多个数值。当服务小区电平高时，容忍的偏置值高，电平低时，容忍的偏置值低。
基站控制器20包括：

筛选模块23，设置为：筛选满足条件的邻区进行切换。当邻区下行的电平值与电平偏置数的和大于等于服务小区下行的电平值与功率补偿的和时，则邻区为符合切换条件的小区，可以选择这些小区进行切换。若否，则不进行切换，继续收集测量报告判断邻区是否满足条件。
本发明实施例中，通过无线操作维护中心10根据服务小区通信条件的不同，设定不同的邻区电平偏置数，该电平偏置数为正值。基站控制器20获取到服务小区和邻区的电平值时，将邻区电平值与该电平偏置数相加，得到大于邻区实际电平值的数值，再判断该数值是否大于等于服务小区的接收信号电平平均值-60与功率补偿的和，即以该运算值作为判断依据判断邻区电平是否高于服务小区电平，若是，则选择该邻区进行切换。本发明实施例当存在高电平质差情况时服务小区切换可以切换到电平相对较弱的邻小区，避免切入质量更差的小区，保证了切换的准确性。因此，采用本发明实施例的系统可以降低掉话率指标，改善用户感知度，提升运营商竞争力。

切换模块24，设置为：以邻区电平大于等于服务小区电平为切换条件执行切换流程；即切换模块24按原有的切换流程进行判决，如果存在可以切换的小区，则说明存在信号相对较好的邻区，可以选择这些小区进行切换，不必执行本发明实施例的流程。
判断模块22还设置为：可进行切换的邻区数是否为0，若是，则执行判断高电平质差切换开关是否开启。当按原有流程进行切换时，若判决可进行切换的邻区数是否为0，若是，则说明邻区的信号均弱于服务小区，此时，执行本发明实施例的切换流程，首先判断高电平质差切换开关是否开启。
本发明一实施例中，所述配置模块11设置为：配置高电平质差切换开关、邻区电平偏置数和服务小区需满足的电平门限，并将所述高电平质差切换开关、邻区电平偏置数和服务小区需满足的电平门限同步到基站控制器。本实施例在前述实施例的基础上增加本小区需满足的电平门限参数，避免人工设置GoodLevBadRQoffset参数不合理，在服务小区电平低时切入了无线质量更差的小区。该参数与GoodLevBadRQoffset配合使用控制切换效果更好，默认值为30，表示-80dBm。本发明实施例中，判断模块22还设置为：在在高电平质差切换开关处于开启状态时，判断服务小区下行的电平值是否大于服务小区需满足的电平门限，若是，则判断邻区下行的电平值与电平偏置数的和是否大于等于服务小区下行的电平值与功率补偿的和。
前述实施例中，筛选模块23还设置为：对满足条件的小区进行排序，按序选择邻区进行切换，以进一步保障通话质量。
