带宽码分多址（Wideband Code Division Multiple Access, WCDMA )系统 中的扰码规则类似于全球移动通讯系统 （ Global System of Mobile communication, GSM )系统中的频率规划，主要是为小区分配扰码， WCDMA 系统中下行链路共有 512个扰码， 每个小区分配一个扰码作为该小区的识别 参数之一， 当小区的数量超过 512个时， 可重复分配扰码， 即多个小区使用 相同的扰码。
由于网络规划的错误， 可能会出现扰码冲突的情况， 其中扰码冲突是指 主小区的相邻的两个小区配置了相同了扰码， 当主小区的相邻小区出现4 码 冲突时， 易产生小区切换失败的情况， 例如： 当用户设备（User Equipment, UE )在主小区向小区 A移动时， 因相部小区 A、 B配置了相同的 4尤码， 主小 区将向小区 B发起小区切换， 导致小区切换失败， 使得 UE在移动过程中出 现掉话掉线的情况， 影响用户的体验， 然而， 现有技术中， 并未有有效的检 测扰码冲突的方法， 此外， 现有技术中也常易出现漏配邻区的情况， 但并未 有有效的确定该漏配邻区是哪个小区的方法。

步骤 201至 202描述的内容与图 1所示实施例中步骤 101至 102描述的 内容相似， 此处不再赘述。
203、 当在 UE所在小区的邻区的扰码中查找到测量小区的扰码时， 则判 断在预置的 UE所在小区的邻区 SFN差值表中，与测量小区的扰码对应的 SFN 差值是否等于测量小区的 SFN差值；
在本发明实施例中， 检测设备中预先设置了所管辖范围内的每个小区的 邻区 SFN差值表，在该邻区 SFN差值表中包含配置为某个小区的邻区的扰码 及 SFN差值之间的关系，此外该邻区 SFN差值表还可以是配置为某个小区的 邻区的小区标识、 扰码、 SFN差值之间的对应关系。 例如， 若小区 A的邻区 包含小区^ 小区 C和小区 D, 则检测设备中将包含小区 A的邻区 SFN差值 表， 且该小区 A的邻区 SFN差值表中包含小区 B的扰码与小区 B的 SFN和 小区 A的 SFN之间的差值的对应关系、 及小区 C的扰码与小区 C的 SFN和 小区 A的 SFN之间的差值的对应关系、 及小区 D的扰码与小区 D的 SFN和 小区 A的 SFN之间的差值的对应关系， 此外， 在该对应关系中， 还可加上小 区的小区标识， 为了更好的理解， 请参阅表 1 , 表 1为小区 A的邻区 SFN差 值表的参考表格:

小区 A的邻区 SFN差值表
在本发明实施例中， 检测设备可通过查找 UE所在小区的邻区 SFN差值 表， 确定测量小区的扰码是否在该邻区 SFN差值表中， 当在 UE所在小区的 邻区的 SFN差值表包含的扰码中查找到测量小区的扰码时， 则判断在该 UE 所在小区的邻区 SFN差值表中，与测量小区的扰码对应的 SFN差值是否等于 测量小区的 SFN差值。
204、 若在邻区 SFN差值表中与测量小区的扰码对应的 SFN差值不等于 测量小区的 SFN差值， 则确定测量小区为 4尤码冲突小区；
在本发明实施例中， 若在邻区 SFN差值表中与测量报告中的测量小区的 扰码对应的 SFN差值不等于计算得到的测量小区的 SFN差值，则检测设备将 确定测量小区为扰码冲突小区， 例如： 若检测设备获取的测量报告中的测量 小区的扰码为 80, 且利用测量报告中的第一差值和第二差值计算得到的测量 小区的 SFN差值为 70, 查找上述的表 1 , 在表 1中与扰码 80对应的 SFN差 值为 45 , 与计算得到的测量小区的 SFN差值 70不相等， 因此， 检测设备可 确定测量小区为 4尤码冲突小区。
在本发明实施例中， 当 UE所在小区的邻区 SFN差值表中， 与测量小区 的扰码对应的 SFN差值等于计算得到的测量小区的 SFN差值，则检测设备可 确定测量小区为 UE所在小区的邻区， 为非 4尤码冲突小区。
需要说明的是， 在本发明实施例中， 检测设备在确定测量小区为扰码冲 突小区之后， 还可进一步根据测量小区的扰码及测量小区的 SFN差值确定测 量小区的小区标识， 下面的步骤将具体的介绍测量小区的小区标识的确定过 程。
205、 查找相对 SFN差值表， 确定与获取的 UE所在小区的小区标识对应 的相对 SFN差值为所述 UE所在小区的相对 SFN差值； 在本发明实施例中， 当 WCDMA网络中有 UE接入时， 检测设备可通过 UE发送的测量报告收集 WCDMA网络连续覆盖范围内的所有小区的邻区信 息， 建立相对 SFN差值表， 其中， "相对 SFN差值" 的定义为： 在连续覆盖 范围内，指定任意一个小区为标准小区，所有小区的 SFN与该标准小区的 SFN 之间的差值加上 256得到的和对 256进行取模运算， 得到的值作为该小区的 相对 SFN差值， 其中， 标准小区的相对 SFN差值为 0。
为了更好的理解小区的相对 SFN差值， 请参阅图 3 , 为本发明中小区的 邻区关系的示意图， 图 3 中， 方框表示小区， 方框中的数字表示该小区的相 对 SFN差值， 方框之间的连线表示小区之间的相邻关系， 箭头上的数字表示 箭头连接的小区相对于与箭尾连接的小区的 SFN差值， 例如， 小区 （cell ) 5 与 cell7之间的箭头的上数字为 10, 则该数字 10表示 cell7的 SFN减去 cell5 的 SFN得到的 SFN差值， 且在图 3中， Cell3为计算相对 SFN差值的标准小 区， 其相对 SFN差值为 0, Cell 1至 Cell 10的相对 SFN差值可才艮据其相对于 邻区的 SFN差值及邻区的相对 SFN差值计算出来， 具体的计算方式可以是：
R-SFN(n)={R-SFN(m)+OFF(n)+256}mod256 ( 2 ) ； 其中， n和 m分别代表小区的标识， 且小区 n和小区 m相邻， R-SFN(n) 表示小区 n的相对 SFN差值， R-SFN(m)表示小区 m的相对 SFN差值， OFF(n) 表示小区 n相对于小区 m的 SFN差值。
需要说明的是， 在本发明实施例中， 相对 SFN差值表中至少包含小区的 小区标识、 扰码与小区的相对 SFN差值之间的对应关系， 此外， 相对 SFN差 值表中的对应关系还可以是： 本小区的小区标识、 本小区扰码、 邻区的小区 标识、 邻区的 SFN相对于本小区的 SFN之间的 SFN差值、 相对 SFN差值之 间的关系， 为了更好的的理解，基于图 6可得到表 2所示的相对 SFN差值表：

表 2: 相对 SFN差值表
在表 2 中， 本小区的小区标识是指小区自身的小区标识， 邻区是指本小 区的相邻小区， 且在表 2中， Cell 3为标准小区。
需要说明的是， 在本发明实施例中， 小区的小区标识具有唯一性。
在本发明实施例中， 为了确定扰码冲突小区的小区标识， 检测设备将获 取 UE所在小区的小区标识， 查找相对 SFN差值表， 确定与获取的 UE所在 小区的小区标识对应的相对 SFN差值为该 UE所在小区的相对 SFN差值。
206、 利用测量小区的 SFN差值与 UE所在小区的相对 SFN差值计算测 量小区的相对 SFN差值；
在本发明实施例中，检测设备在确定 UE所在小区的相对 SFN差值之后， 将利用测量小区的 SFN差值与 UE所在小区的相对 SFN计算测量小区的相对 SFN差值， 具体可以是： 检测设备将测量小区的 SFN差值、 UE所在小区的 相对 SFN差值代入公式（ 2 ) 中， 得到测量小区的相对 SFN差值。 例如： 参 考表 2, 若 UE所在小区为 cell7, 根据 UE发送的测量报告中的第一差值及第 二差值得到的测量小区的 SFN差值为 232, 则查找表 2中的 cell7的相对 SFN 差值为 17, 则确定测量小区的相对 SFN差值为 ( 17+232+256 ) mod256, 得 到 249, 因此， 测量小区的相对 SFN差值为 249。
207、 查找相对 SFN差值表， 确定与测量小区的相对 SFN差值及测量小 区的 4尤码对应的小区标识为测量小区的小区标识。
在本发明实施例中， 检测设备在确定测量小区的相对 SFN差值之后， 可 查找相对 SFN差值表，确定与测量小区的相对 SFN差值及其扰码对应的小区 标识测量小区的小区标识， 其中， 相对 SFN差值表中至少包含小区的小区标 识、 扰码及小区的的相对 SFN差值之间的对应关系。 例如： 若测量小区的相 对 SFN差值为 249,扰码为 97, 则查找表 2,可确定 cell6即为扰码冲突小区。
需要说明的是， 在本发明实施例中， 检测设备在确定扰码冲突小区的小 区标识之后， 可发出警报， 或者修改扰码冲突小区的扰码， 并将修改扰码后 的小区配置为 UE所在小区的邻区。
在本发明实施例中， 通过利用测量报告中携带的第一差值与第二差值计 算测量小区的 SFN差值， 且当在 UE所在小区的邻区的扰码中查找到该测量 小区的扰码时， 判断计算得到的测量小区的 SFN差值是否与 UE所在小区的 邻区 SFN差值表中与测量小区的扰码对应的 SFN差值相等， 若不相等， 则确 定该测量小区为扰码冲突小区， 优选的， 检测设备还可进一步的确定该扰码 冲突小区的小区标识， 能够有效的检测到扰码冲突及确定扰码冲突小区的小 区标识。
图 2所示实施例中步骤 205至 207描述了在确定测量小区为扰码冲突小 区之后， 确定测量小区的小区标识的一种方法， 下面将介绍另外一种在确定 测量小区为扰码冲突小区之后，确定测量小区的小区标识的方法，请参阅图 4, 为本发明实施例中， 扰码冲突小区的小区标识的确定方法， 包括：
401、 确定测量小区为扰码冲突小区之后， 确定所管辖范围内扰码与测量 小区的扰码相同的小区为第一小区；
在本发明实施例中， 检测设备在确定测量小区为扰码冲突小区之后， 检 测设备将在其所管辖范围内获得扰码与测量小区的扰码相同的小区为第一小 区。 例如： 若测量小区的扰码为 75 , 检测设备所管辖范围内包含 200个小区， 则设备将查找该 200个小区的 4尤码， 将该 200个小区中 4尤码为 75的小区作为 第一小区。
402、 根据预置的第一小区的邻区 SFN差值表计算 UE所在小区的 SFN 与第一小区的 SFN之间的第三差值；
403、确定与测量小区的 SFN差值相等的第三差值对应的第一小区的小区 标识为测量小区的小区标识。
在本发明实施例中， 检测设备在获得所有的扰码与测量小区的扰码相同 的第一小区之后， 将根据预置的第一小区的邻区 SFN差值表计算 UE所在小 区的 SFN与第一小区的 SFN之间的第三差值， 确定与测量小区的 SFN差值 相同的第三差值对应的第一小区的小区标识为测量小区的小区标识， 例如： 若扰码与测量小区的扰码相同的第一小区包括小区 A, 小区 D, 小区 F, 且 UE所在的小区为小区 B, 则设备将依次计算小区 B的 SFN与小区 A的 SFN 之间的差值， 小区 B的 SFN与小区 D的 SFN之间的差值， 及小区 B的 SFN 与小区 F的 SFN之间的差值， 若小区 B的 SFN与小区 D的 SFN之间的差值 等于测量小区的 SFN差值， 则确定小区 D即为测量小区， 即小区 D为 UE所 在小区的扰码冲突小区。
具体的， 在本发明实施例中， 根据第一小区的邻区 SFN差值表计算 UE 所在小区的 SFN与第一小区的 SFN之间的第一差值的方法可以为： 查找第一 小区的邻区 SFN差值表， 确定该第一小区与 UE所在的小区之间的邻区连通 路线， 并将根据该路线上小区之间的 SFN差值关系计算 UE所在小区的 SFN 与第一小区的 SFN之间的第一差值， 例如： 请参阅图 3 , 若第一小区为 cell3 , UE 所在小区为 cell9 , 则第一' 区与 UE 所在小区之间的邻区连通路线为 cell3-cell5-cell7-cell8-cell9 , 则 cell9与 cell3之间的 SFN差值的计算方式为： OFF= ( 7+10+4+251 ) mod256=16, 因此， UE所在小区 cell9的 SFN与第一' J、 区 cell3之间的第一差值为 16。
在本发明实施例中， 检测设备在确定测量小区为扰码冲突小区之后， 将 查找其管辖范围内的小区的扰码， 确定扰码与测量小区的扰码相同的小区为 第一小区， 并根据该第一小区的邻区 SFN差值表计算 UE所在小区的 SFN与 第一小区的 SFN之间的第一差值，且确定等于测量小区的 SFN差值的第一差 值对应的第一小区为测量小区， 即该第一小区的小区标识为扰码冲突小区， 能够有效的确定扰码冲突小区的小区标识。
需要说明的是，在本发明实施例中， 当在 UE所在小区的邻区的扰码中查 找到测量小区的扰码时， 可按照图 1、 图 2或图 4所示实施例描述的内容确定 该测量小区是否为扰码冲突小区， 及当该测量小区为扰码冲突小区时， 确定 该侧脸小区的小区标识，而当在 UE所在小区的邻区的扰码中未查找到测量小 区的扰码时，检测设备可确定该测量小区为 UE所在小区的漏配邻区， 下面将 详细的介绍检测设备确定漏配邻区的小区标识的方法， 请参阅图 5 , 为本发明 实施例中， 漏配邻区的小区标识的确定方法， 包括：
501、 获取 UE发送的测量报告， 测量报告中包含测量小区的扰码， UE 的 CFN与测量小区的 SFN之间的第一差值，及 UE的 CFN与 UE所在小区的 SFN之间的第二差值；
502、 利用第一差值与第二差值计算测量小区的 SFN差值；
步骤 501至 502描述的内容与图 1所示实施例中步骤 101至 102描述的 内容相似， 此处不再赘述。
503、 当在 UE所在小区的邻区的扰码中未查找到测量小区的扰码时， 则 确定测量小区为漏配邻区；
在本发明实施例中， 检测设备在计算得到测量小区的 SFN差值之后， 将 在 UE所在小区的邻区的扰码中查找测量小区的扰码，具体的可以是在 UE所 在小区的邻区 SFN差值表中的扰码中查找测量小区的扰码， 当在 UE所在小 区的邻区的扰码中未查找到测量小区的扰码时， 则检测设备确定测量小区为 漏配邻区。
在本发明实施例中， 检测设备在确定测量小区为漏配邻区之后， 可进一 步根据测量小区的扰码及测量小区的 SFN差值确定测量小区的小区标识， 下 面的步骤具体描述了检测设备确定测量小区的小区标识的过程。

505、 利用测量小区的 SFN差值与 UE所在小区的相对 SFN差值确定所 述测量小区的相对 SFN差值；
在本发明实施例中，检测设备在确定 UE所在小区的相对 SFN差值之后， 将利用测量小区的 SFN差值与 UE所在小区的相对 SFN差值确定测量小区的 相对 SFN差值， 具体可以是： 检测设备将测量小区的 SFN差值、 UE所在小 区的相对 SFN差值代入公式（2 ) 中， 得到测量小区的相对 SFN差值。
506、 查找相对 SFN差值表， 确定与测量小区的相对 SFN差值及测量小 区的 4尤码对应的小区标识为测量小区的小区标识；
在本发明实施例中， 检测设备在确定测量小区的相对 SFN差值之后， 可 通过查找相对 SFN差值表，确定与测量小区的相对 SFN差值及其扰码对应的 'J、区标识为测量小区的小区标识。
507、 将测量小区配置成 UE所在小区的邻区；
在本发明实施例中， 检测设备在确定测量小区的小区标识之后， 因该测 量小区为漏配邻区，检测设备可将该测量小区配置成 UE所在小区的邻区，其 中， 邻区配置的方法为现有技术， 此处不做赞述。
508、 将测量小区的扰码与测量小区的 SFN 差值之间的对应关系添加至 UE所在小区的邻区 SFN差值表中。
在本发明实施例中，检测设备在将测量小区配置成 UE所在小区的邻区之 后， 将该测量小区的扰码及测量小区的 SFN差值之间的对应关系添加至 UE 所在小区的邻区 SFN差值表中。
在本发明实施例中， 通过利用测量报告中携带的第一差值与第二差值计 算测量小区的 SFN差值， 且当在 UE所在小区的邻区的扰码中未查找到该测 量小区的扰码时， 确定该小区为漏配邻区， 并进一步确定该测量小区的小区 标识， 具体的， 检测设备通过确定测量小区的相对 SFN差值， 并在相对 SFN 差值表中查找与该测量小区的相对 SFN差值和扰码对应的小区标识， 则该小 区标识即为测量小区的小区标识， 且还可将该漏配邻区 （测量小区） 配置成 UE所在小区的邻区， 因此， 能够有效的检测到漏配邻区及确定漏配邻区的小 区标识， 且通过将漏配邻区配置成 UE所在小区的邻区， 有效避免 UE在小区 切换时出现掉话掉线等情况， 改善系统性能及用户的体验。
图 5所示实施例中步骤 504至 506描述了在确定测量小区为漏配邻区之 后， 确定测量小区的小区标识的一种方法， 下面将介绍另外一种在确定测量 小区为漏配邻区之后， 确定测量小区的小区标识的方法， 请参阅图 6, 为本发 明实施例中， 漏配邻区的小区标识的确定方法， 包括：

在本发明实施例中， 检测设备在确定测量小区为漏配邻区之后， 检测设 备将在其所管辖范围内获得扰码与测量小区的扰码相同的小区为第一小区。 例如： 若测量小区的扰码为 75, 检测设备所管辖范围内包含 200个小区， 则 设备将查找该 200个小区的扰码， 将该 200个小区中扰码为 75的小区作为第 一小区。
602、 根据预置的第一小区的邻区 SFN差值表计算 UE所在小区的 SFN 与第一小区的 SFN之间的第三差值；

在本发明实施例中， 检测设备在获得所有的扰码与测量小区的扰码相同 的第一小区之后， 将根据预置的第一小区的邻区 SFN差值表计算 UE所在小 区的 SFN与第一小区的 SFN之间的第三差值， 确定与测量小区的 SFN差值 相同的第三差值对应的第一小区的小区标识为测量小区的小区标识， 例如： 若扰码与测量小区的扰码相同的第一小区包括小区 A, 小区 D, 小区 F, 且 UE所在的小区为小区 B, 则设备将依次计算小区 B的 SFN与小区 A的 SFN 之间的差值， 小区 B的 SFN与小区 D的 SFN之间的差值， 及小区 B的 SFN 与小区 F的 SFN之间的差值， 若小区 B的 SFN与小区 D的 SFN之间的差值 等于测量小区的 SFN差值， 则确定小区 D即为测量小区， 即小区 D为 UE所 在小区的漏配邻区。
具体的， 在本发明实施例中， 根据第一小区的邻区 SFN差值表计算 UE 所在小区的 SFN与第一小区的 SFN之间的第一差值的方法可以为： 查找第一 小区的邻区 SFN差值表， 确定该第一小区与 UE所在的小区之间的邻区连通 路线， 并将根据该路线上小区之间的 SFN差值关系计算 UE所在小区的 SFN 与第一小区的 SFN之间的第一差值， 例如： 请参阅图 3 , 若第一小区为 cell3 , UE 所在小区为 cell9 , 则第一' 区与 UE 所在小区之间的邻区连通路线为 cell3-cell5-cell7-cell8-cell9 , 则 cell9与 cell3之间的 SFN差值的计算方式为： OFF= ( 7+10+4+251 ) mod256=16, 因此， UE所在小区 cell9的 SFN与第一' J、 区 cell3之间的第一差值为 16。
在本发明实施例中， 检测设备在确定测量小区为漏配邻区之后， 将查找 其管辖范围内的小区的扰码， 确定扰码与测量小区的扰码相同的小区为第一 小区， 并根据该第一小区的邻区 SFN差值表计算 UE所在小区的 SFN与第一 小区的 SFN之间的第一差值，且确定等于测量小区的 SFN差值的第一差值对 应的第一' 区为测量小区， 即该第一小区的小区标识为漏配邻区的小区标识， 能够有效的确定当测量小区为漏配邻区时该漏配邻区的小区标识。
