Description

小区失效检测方法及装置、 终端切换控制方法及装置 本申请要求于 2012 年 9 月 29 日提交中国专利局、 申请号为 201210375266.5、 发明名称为"小区失效检测方法及装置、 终端切换控制方 法及装置"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
[01 ] 本发明涉及通信技术领域, 尤其涉及小区失效检测方法及装置、 终端 切换控制方法及装置。 背景技术
[02]在通信过程中可能出现小区失效, 小区失效是指小区无法为通信网 络中的所有或部分业务提供正常的空口服务。 引起小区失效的原因有很 多, 除了由已知故障引起的小区失效外, 例如硬件故障、 传输故障等, 还有由隐性故障引起的小区失效。
[ 03 ]针对隐性故障引起的小区失效, 现有技术中通常采用关键性能指标 (KPI, Key Performance Indicator) 监控方式来进行小区失效检测, 即在 当前通信网络中对预设时间段内的 KPI进行监控, 其中, 所监控的 KPI 一般包括话务量、 接入次数、 接入成功率、 掉话次数、 掉话率、 切换次 数和切换成功率等, 当监控到某些 KPI不属于预先设定的正常数值范围 时, 则可以确认检测到小区失效。
[04]现有技术中进行小区失效检测时, 预先设置 KPI的正常数值范围, 由于所有小区设置的 KPI的正常数值范围均相同, 因此当某个小区处于 特定场景时, 例如, 人口密度非常小时, 该小区虽然未失效, 但是由于 接入次数比较少, 不属于预先设定的正常数值范围, 因此会根据检测结 果将小区误判为失效; 又例如, 人口密度非常大时, 该小区虽然失效, 但是由于接入次数仍然比较多, 属于预先设定的正常数值范围, 因此会 根据检测结果确认该小区正常, 由此出现漏判。 由此可知, 现有技术中 的小区失效检测方法准确度较低。 [05]通常, 在确认小区失效后, 还要控制该小区内的终端切换到其他小 区, 现有技术中控制该小区内的终端切换到当前网络中该小区的相邻小 区, 由于终端可能处于相邻小区覆盖的远点, 甚至不在相邻小区的覆盖 范围, 因此, 终端切换后容易掉话, 导致业务体验差。 发明内容

[42]下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进 行清楚、 完整的描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没 有作出创造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的 范围。
[43]如图 1 所示, 为本发明小区失效检测方法的一个实施例, 其具体处 理过程如下:
[44] 步骤 101, 当检测到被第一网络和第二网络共同覆盖的小区在第一 网络中疑似失效时, 获得小区在第一网络中的 KPI, 以及获得小区在第 二网络中的 ΚΡΙ。 [45]其中, 小区归属于第一网络, 该小区除了被第一网络覆盖外, 还被 至少一个其他网络所覆盖, 为描述方便, 将覆盖该小区的一个其他网络 称为第二网络。
[46]本发明实施例中, 该小区可以为第一网络和第二网络的共站小区, 即该小区所归属的第一网络的基站和该小区所归属的第二网络的基站的 站址相同。
[47]通常情况下, 覆盖同一区域的多个网络具有不同的网络制式, 即第 一网络的网络制式和第二网络的网络制式通常不同, 例如, 第一网络为 长期演进 (LTE, Long Term Evolution ) 网络, 第二网络为码分多址 (CDMA , Code Division Multiple Access) 网络。
[48]本发明实施例中, 可以通过 KPI监控方式, 检测到小区在第一网络 中疑似失效。 例如, 预先设置 KPI的疑似失效数值范围, 当对第一预设 时间段内的 KPI进行监控时, 检测到 KPI属于疑似失效数值范围时, 确 认检测到小区在第一网络中疑似失效。 为了及时检测出小区疑似失效, 上述第一预设时间段通常设置为较短的时间, 例如, 可以是半小时或一 小时等。
[ 49 ]在检测到小区在第一网络中疑似失效时, 获得小区在第一网络中的 KPI, 以及获得小区在第二网络中的 KPI, 具体可以是: 获得小区在第一 网络中的第二预设时间段内的 ΚΡΙ, 以及获得小区在第二网络中的第二 预设时间段内的 ΚΡΙ。 为了在检测出小区疑似失效后, 进一步确认该小 区是否为失效小区的准确度较高, 上述第二预设时间段通常设置为较长 的时间, 可以是一天或两天等。
[50]其中, 获得小区在第二网络中的 ΚΡΙ时, 应与获得的小区在第一网 络中的 ΚΡΙ包含的参数相同,例如, 当获得小区在第一网络中的 ΚΡΙ时, 仅获取接入次数, 那么, 当获得小区在第二网络中的 ΚΡΙ时, 也仅获取 接入次数。
[51 ]本发明实施例中, 可以根据小区在第一网络中的小区标识, 从该小 区在第二网络的基站中获得该小区在第二网络中的 ΚΡ I。
[52] 步骤 102, 根据小区在第一网络中的 ΚΡΙ 和小区在第二网络中的 ΚΡΙ, 确认小区在第一网络中是否为失效小区。 [53] 由于被两个网络共同覆盖的小区的 KPI具有相关性, 即 KPI不应该 相差过大, 因此可以计算小区在第一网络中的 KPI与小区在第二网络中 的 KPI的相关性参数, 该相关性参数可以为比值或差值等, 当相关性参 数在预设区间内时, 说明小区在两个网络中的 KPI相关, 确认小区在第 一网络中不为失效小区; 当相关性参数不在预设区间内时, 说明小区在 两个网络中的 KPI不相关, 确认小区在第一网络中为失效小区。
[54]此外, 当获取的第一网络和第二网络中的 KPI仅包含一项话务统计 指标时, 例如, 仅包含话务量时, 根据判断小区在两个网络中的该项话 务统计指标是否具有相关性, 来确定小区在两个网络中的 KPI是否具有 相关性; 当获取的第一网络和第二网络中的 KPI包含两项以上的话务统 计指标时, 例如, 包含话务量和接入次数时, 可以在获取的 KPI中包含 的所有话务统计指标都具有相关性时, 确定小区在两个网络中的 KPI具 有相关性。
[55] 由上可见, 本发明实施例的小区失效检测方法中, 当检测到被第一 网络和第二网络共同覆盖的小区在第一网络中疑似失效时, 不仅要获得 该小区在第一网络中的 KPI, 还要获得该小区在第二网络中的 ΚΡΙ, 根 据该小区在两个网络中 ΚΡΙ, 来进一步确认该小区是否为失效小区。 由 于正常情况下, 小区在两个网络中的 ΚΡΙ具有相关性, 因此通过将小区 在第一网络中的 ΚΡΙ和小区在第二网络中的 ΚΡΙ结合起来, 用以确认小 区在第一网络中是否失效, 可以有效提高小区失效检测的准确度。
[56]如图 2所示, 为本发明小区失效检测方法的另一个实施例, 其中, 待检测的小区为第一网络和第二网络的共站小区, 通过小区在第一网络 中的 ΚΡΙ与小区在第二网络中的 ΚΡΙ的相关性参数是否在预设区间内, 来确认小区是否为失效小区, 其具体处理过程如下: [57] 步骤 201, 当通过 ΚΡΙ监控, 检测到小区在第一网络中疑似失效时, 获得小区在第一网络中的 ΚΡΙ, 以及获得小区在第二网络中的 ΚΡΙ。
[58] 步骤 202, 判断小区在两个网络中的 ΚΡΙ的相关性参数是否在预设 区间内。 若判断结果为是, 则执行步骤 203 ; 若判断结果为否, 则执行 步骤 204。 [59]其中, 上述相关性参数可以为比值或差值等, 例如, 当相关性参数 为差值, 预设区间为 [0, 15]时, 若步骤 201 中获得的 KPI仅包含接入次 数一项话务统计指标, 并且小区在第一网络中的接入次数为 0, 小区在 第二网络中的接入次数为 100, 则可以计算出小区在第一网络中的 KPI 与小区在第二网络中的 KPI的相关性参数为 100, 从而可以判断出该相 关性参数不在预设区间内。
[60] 步骤 203, 确认小区在第一网络中不为失效小区。 [61 ] 步骤 204, 确认小区在第一网络中为失效小区。
[62]如图 3所示, 为本发明小区失效检测方法的另一个实施例, 其中, 待检测的小区为 LTE 网络和 CDMA2000 网络的共站小区, 获得小区在 LTE网络和 CDMA2000 网络中的 KPI时, 仅获取话务量, 用以确认小区 在 LTE网络中是否失效, 其具体处理过程如下:
[63] 步骤 301, 当检测到小区在 LTE 网络中疑似失效时, 获得该小区在 LTE网络中的话务量, 以及获得小区在 CDMA2000 网络中的话务量。
[64]本发明实施例中, 可以通过 KPI监控方式, 检测到小区在 LTE网络 中疑似失效。 例如, 预先设置 KPI的疑似失效数值范围, 在一段时间内, 检测到 KPI属于疑似失效数值范围时, 确认检测到小区在第一网络中疑 似失效。 为了及时检测出小区疑似失效, 上述一段时间设置为较短的时 间, 例如, 可以是半小时或一小时等。
[65]其中, 获得的话务量为预设时间段内的话务量, 例如, 该预设时间 段为 1 天。
[66] 步骤 302, 判断小区在两个网络中的话务量的比值是否在预设区间 内。 若判断结果为是, 则执行步骤 303 ; 若判断结果为否, 则执行步骤 304。
[67]例如, 预设区间为 [0.5,1], 步骤 301 中获得的小区在 LTE 网络中的 话务量为 0, 小区在 CDMA2000 网络中的话务量为 100小时, 则可以计 算出小区在两个网络中的话务量的比值为 0, 从而判断出该比值不在预 设区间内。
[68] 步骤 303, 确认小区在 LTE网络中不为失效小区。 [69] 步骤 304, 确认小区在 LTE网络中为失效小区。
[70]与本发明小区失效检测方法的实施例相对应, 本发明还提供了小区 失效检测装置的实施例。
[71 ]如图 4所示, 为本发明小区失效检测装置的一个实施例, 该装置包 括: 获得单元 401和确认单元 402。
[72]其中, 获得单元 401, 用于当检测到被第一网络和第二网络共同覆 盖的小区在所述第一网络中疑似失效时, 获得所述小区在所述第一网络 中的 KPI, 以及获得所述小区在所述第二网络中的 ΚΡΙ ;
[73]确认单元 402, 用于根据所述获得单元 401 获得的所述小区在所述 第一网络中的 ΚΡΙ和所述小区在所述第二网络中的 ΚΡΙ, 确认所述小区 在所述第一网络中是否为失效小区。

[94]本发明还提供了终端切换控制方法的实施例。
[95]如图 7所示, 为本发明终端切换控制方法的一个实施例, 该方法用 于控制上述小区失效检测方法所确认的失效小区内的终端进行切换, 其 具体处理过程如下:
[96] 步骤 701, 从第一网络中的除失效小区外的其他小区和第二网络中 的小区中选择一个小区作为目标小区。
[97]其中, 在确认小区为失效小区后, 控制终端切换前, 为避免其他终 端再接入该失效小区, 可以将小区设置为禁止驻留、接入和切换入状态。
[98]在选择目标小区时, 可以根据终端在各小区中能够接收到的信号的 信号质量, 从第一网络中的除失效小区外的其他小区和第二网络中的小 区中选择一个信号质量较好的小区作为目标小区。 [99]本发明实施例中, 为了获得终端在各小区中能够接收到的信号的信 号质量, 在从第一网络中的除所述失效小区外的其他小区和第二网络中 的小区中选择一个小区作为目标小区之前, 还可以包括下述处理流程: 先向失效小区内的终端发送测量指示消息, 测量指示消息用于指示终端 测量第一网络中的小区的信号质量和第二网络中的小区的信号质量, 然 后接收终端根据测量指示消息返回的测量报告, 测量报告中包含第一网 络中的小区的小区标识与信号质量的对应关系和第二网络中的小区的小 区标识与信号质量的对应关系, 以使后续可以根据测量报告, 从测量报 告中所包含的第一网络中的小区的小区标识和第二网络中的小区的小区 标识中, 选择最强信号质量所对应的小区标识, 将选择出的小区标识对 应的小区作为目标小区。
[1 00] 此外, 在接收到终端返回的测量报告后, 还可以进一步根据测量 报告中所携带的小区标识, 获得小区标识对应的小区的负荷状态, 以使 后续可以根据测量报告中所携带的小区标识与信号质量的对应关系和获 得的小区标识对应的小区的负荷状态, 从第一网络中的小区和第二网络 中的小区中选择出信号质量与负荷状态均满足预设条件的小区作为目标 小区。
[1 01 ] 步骤 702, 向失效小区内的终端发送携带有目标小区的小区标识 的切换指示消息, 切换指示消息用于指示终端从失效小区切换到目标小 区。
[1 02] 由上可见, 采用本发明实施例的终端切换控制方法, 在确认小区 为第一网络中的失效小区后, 控制终端切换时, 不是仅从第一网络中该 失效小区的相邻小区中选择一个小区作为终端切换的目标小区, 而是从 第一网络中的除该失效小区外的其他小区和第二网络中的小区中选择一 个小区作为终端切换的目标小区, 由于第二网络中存在覆盖该失效小区 的小区, 因此所选择的目标小区中, 不会出现终端处于目标小区覆盖的 远点, 或者超过目标小区覆盖范围的问题, 从而终端切换后不会出现容 易掉话的问题, 业务体验好。
[1 03] 如图 8所示, 为本发明终端切换控制方法的另一个实施例, 该方 法用于控制上述小区失效检测方法所确认的失效小区内的终端进行切 换, 其中, 通过获得终端在各小区中能够接收到的信号的信号质量来选 择目标小区, 其具体处理过程如下:

[1 06] 步骤 803, 根据测量报告, 从测量报告中所包含的第一网络中的 小区的小区标识和第二网络中的小区的小区标识中, 选择最强信号质量 所对应的小区标识, 将选择出的小区标识对应的小区作为目标小区。
[1 07] 步骤 804, 向失效小区内的终端发送携带有目标小区的小区标识 的切换指示消息, 切换指示消息用于指示终端从该失效小区切换到目标 小区。
[1 08] 如图 9所示, 为本发明终端切换控制方法的另一个实施例, 该方 法用于控制上述小区失效检测方法所确认的失效小区内的终端进行切 换, 其中, 通过获得终端在各小区中能够接收到的信号的信号质量和各 小区的负荷状态来选择目标小区, 其具体处理过程如下:
[1 09] 步骤 901, 向失效小区内的终端发送测量指示消息, 测量指示消 息用于指示终端测量第一网络中的小区的信号质量和第二网络中的小区 的信号质量。
[1 1 0] 步骤 902, 接收终端根据测量指示消息返回的测量报告, 测量报 告中包含第一网络中的小区的小区标识与信号质量的对应关系和第二网 络中的小区的小区标识与信号质量的对应关系。
[1 1 1 ] 步骤 903, 根据测量报告中所携带的小区标识, 获得小区标识对 应的小区的负荷状态。
[1 1 2] 步骤 904, 根据测量报告中所携带的小区标识与信号质量的对应 关系和获得的小区标识对应的小区的负荷状态, 从第一网络中的小区和 第二网络中的小区中选择出信号质量与负荷状态均满足预设条件的小区 作为目标小区
[1 1 3] 步骤 905, 向失效小区内的终端发送携带有目标小区的小区标识 的切换指示消息, 切换指示消息用于指示终端从该失效小区切换到目标 小区。 [1 14] 与本发明终端切换控制方法的实施例相对应, 本发明还提供了终 端切换控制装置的实施例。
