Description

一种确定 KPI下降原因的方法及装置 技术领域
本发明涉及通信领域, 尤其涉及一种确定 ΚΡΙ 下降原因的方法 及装置。
背景技术
在无线通信系统的网络运营及维护中, 运营商需投入大量的人 力或物力进行路测, 为了减少运营商在网络运营及维护中进行的路 测工作, 并减少路测不能解决的问题而提出了 MDT (Minimization of Drive Tests, 最 d、 路则) 则量。
目前, 在 MDT 测量中, 当 OSS ( Opera t ion Support Sys tern, 运营支撑系统) 发现某一区域的 KPI ( Key Performance Indicator, 关键绩效指标) 小于预设阔值时, 0SS 发送测量指示给 UE ( User Equipment,用户设备 ),使得 UE根据该测量指示开始进行 MDT测量, 并上报 MDT 测量信息至基站, 且由基站再上报至 0SS, 从而 0SS 可 根据该 MDT 测量信息进行网络优化。 其中, MDT 测量可分为两种: Immediate MDT (立 ^式 MDT)和 Logged MDT (i己录式 MDT)。 具体^; , Immediate MDT是 OSS根据 RRC (Radio Resource Control , 无线资 源控制)协议对 UE进行 MDT配置后, UE在连接态进行 MDT测量, 并 立即上才艮 MDT测量信息至 0SS 的一种 MDT方式; Logged MDT是 OSS 对 UE进行 MDT配置后, UE转入到空闲态进行 MDT测量, 并记录 MDT 测量信息, 且 UE在转到连接态后, 再将记录的 MDT测量信息上报至 该 0SS的一种 MDT方式。
然而, 一方面, 若采用 Immediate MDT进行 MDT测量, 由于 UE 上报 MDT测量信息至网络和 UE上报业务信息至 0SS, 是通过共享的 上行信道实现的, UE通过上行信道上报 MDT测量信息时, 占用了该 上行信道的资源和时间, 因此, 导致 UE上报业务信息时的可用的上 行信道的资源和时间减少, 从而影响了 UE进行上行业务的质量; 另 一方面,在现有的上述两种 MDT测量方式中,由于 UE通过 Immediate MDT测量的上报大量 MDT测量信息至基站, 再由基站转发至 0SS,或 UE 在网络故障排除后, 通过 Logged MDT 测量的上报大量的 MDT 测 量信息至基站, 再由基站转发至 0SS, 因此, 导致网络受到大量集 中的冲击, 使得 0SS处理网络问题的效率低。

实施例一
本发明的实施例提供一种确定 KPI 下降原因的方法, 如图 1 所 示, 涉及基站侧的确定 KPI 下降原因的方法, 该方法可以包括:
S101、 第一基站接收 UE 发送的业务消息, 该业务消息中夹带 ( Piggy Back ) 第一测量信息, 该第一测量信息为该 UE对第一小区 进行业务测量的信息, 该第一小区由该第一基站提供服务。
这里的业务测量可以是 UE在小区所执行的任意测量过程,在本 发明实施例中主要包括 MDT 测量。 需要说明的是, 在无线通信系统 的网络运营及维护中, KPI ( Key Performance Indicator, 关键绩 效指标) 为网络维护阶段参照的重要指标, 而 KPI 下降会影响该 UE 的网络通信, 为了保证 UE的通信质量, 更好的解决网络问题, 本发 明提出一种确定 KPI 下降原因的方法。
其中, KPI可以包括 5种类型的指标。
具体的, KPI可以包括 RRC ( Radio Resource Control , 无线资 源控制协议) 建立请求成功率、 RRC 重建立成功率、 掉话率、 切换 成功率及 E-RAB建立成功率。
需要说明的是, RRC建立请求成功率对应第一门限值、 RRC重建 立成功率对应第二门限值、 掉话率对应第三门限值、 切换成功率对 应第四门限值及 E-RAB ( Enhanced Radio Access Bearer , 增强的 无线接入承载) 建立成功率对应第五门限值, RRC 建立请求成功率 低于第一门限值、 RRC 重建立成功率低于第二门限值、 掉话率低于 第三门限值、 切换成功率低于第四门限值或 E-RAB 建立成功率低于 第五门限值中的任意一项发生即为 0SS( Operat ion Support System, 运营支撑系统) 发现 KPI 下降。 具体的第一门限值、 第二门限值、 第三门限值、 第四门限值和第五门限值的具体值的设定可以根据不 同的运营商的实际情况而决定, 本发明不作限制。
本发明实施例中, UE由第一小区提供服务, 第一小区由第一基 站提供服务。 由于 UE在进行某一业务时, UE需要获知 UE所在小区, 即第一小区的业务测量的信息, 该第一小区的业务测量的信息可以 辅助 UE 进行该某一业务, 因此, UE 在进行某一业务时发送的业务 消息中夹带该第一小区的业务测量的信息。
需要说明的是, 本发明实施例中的 KPI 下降指的是运营商网络 的 KPI 下降。
本发明实施例提供的一种确定 KPI 下降原因的方法中, 第一基 站接收 UE发送的业务消息, 该业务消息中夹带第一测量信息, 该第 一测量信息为该 UE 进行业务时, UE 对第一小区进行业务测量的信 息, 其中, 该第一小区由该第一基站提供服务。
具体的, UE以无线的方式, 通过上行信道发送业务消息至第一 基站, 即第一基站接收 UE发送的业务消息。
可选的, 第一测量信息可以包括第一小区的标识、 第一小区的 信号强度、 第一小区的信号质量、 UE的位置信息、 PDCCH (Physical Downlink Control Cha應 1, 物理下行控制信道) 的块误码率及 PDSCH (Phys ical Downlink Shared Channel , 物理下行共享信道) 的块误码率中的至少一项测量信息。
5102、 第一基站根据业务消息, 获取第一测量信息。
第一基站接收 UE发送的业务消息之后,该第一基站根据业务消 息, 获取第一测量信息。
需要说明的是,由于 UE发送至第一基站的业务消息中夹带第一 测量信息, 因此, 第一基站可以从该业务消息中, 获取该第一测量 信息, 即第一基站收集第一测量信息。
5103、 第一基站根据第一测量信息, 生成 MNT ( Minimized Network Test, 最小化网络测试) 测量信息。
第一基站根据业务消息, 获取第一测量信息之后, 该第一基站 根据第一测量信息, 生成 MNT测量信息。
具体的, 第一基站收集第一测量信息后, 该第一基站将该第一 测量信息用作 0SS确定 KPI 下降原因的测量信息。 第一基站将该第 一;;则量信息、力口上 0SS 可 i只另' J的 IP 头或 SCTP ( Stream Control Transmission Protocol, 流控制传输协议) 头等各种协议头, 打包 上 MNT信封, 即第一基站根据该第一测量信息,生成 MNT测量信息。
需要说明的是, MNT 测量信息为 0SS确定 KPI 下降原因时可能 需要的参数信息,由于该参数信息为第一基站收集的, 因此, 称为 MNT测量信息。
可以理解的是, 一方面, 由于第一基站可以获取第一测量信息, 并根据第一测量信息生成 MNT 测量信息, UE 不用再次专门上报 0SS 确定 KPI 下降原因时需要的参数信息,即 UE 除了进行上行业务的业 务测量外, 不需要进行 MDT测量, 并将该 MDT测量信息上报至第一 基站, 因此, 本发明实施例中, UE 上报 MNT 测量信息不占用 UE 进 行上行业务的信道资源和时间, 从而能够减少了 UE上报开销, 保证 UE进行上行业务的质量; 另一方面, 第一基站获取的第一测量信息 是夹带在 UE上报的业务消息中的, 因此, 第一基站不会一次性接收 大量的测量信息, 从而避免了上报测量信息对网络的冲击。
S104、 第一基站发送 MNT 测量信息至 OSS, 该 MNT 测量信息用 于该 0SS确定 KPI 下降原因。
第一基站根据第一测量信息, 生成 MNT测量信息之后, 第一基 站发送 MNT 测量信息至 0SS, 该 MNT 测量信息用于该 0SS 确定 KPI 下降原因。
具体的, 第一基站通过 itf_N接口发送 MNT测量信息至 0SS。 可选的, 0SS可以包括网络管理系统或网络优化系统。
需要说明的是, 0SS可以获知该 MNT信封中的 MNT测量信息的 功能。
进一步地, 第一基站在 0SS发现 KPI 下降时, 该第一基站发送 MNT测量信息至 0SS, 具体的实现过程将在后续实施例中进行详细地 说明, 此处不进行描述。
可以理解的是, 由于第一基站可以直接生成 MNT测量信息, 当 0SS 需要该 MNT 测量信息时, 第一基站可以直接发送 MNT 测量信息 至 OS s , 从而提高了处理网络问题的效率。
本发明的实施例还提供一种确定 ΚΡΙ 下降原因的方法, 如图 2 所示, 涉及 0SS侧的确定 ΚΡΙ 下降原因的方法, 该方法可以包括:
S20 0SS接收第一基站发送的 ΜΝΤ 测量信息, 该 ΜΝΤ 测量信 息为该第一基站接收 UE 发送的业务消息并根据该业务消息获取第 一测量信息后, 由该第一基站根据该第一测量信息生成的, 该业务 消息中夹带该第一测量信息, 该第一测量信息为该 UE对第一小区进 行业务测量的信息, 该第一小区由该第一基站提供服务。
本发明实施例中, 当 ΚΡΙ 下降时, 0SS接收第一基站发送的 ΜΝΤ 测量信息, 该 ΜΝΤ测量信息是第一基站通过接收 UE发送的业务消息 并根据该业务消息获取第一测量信息后, 由该第一基站根据该第一 测量信息生成的, 其中, 该业务消息中夹带该第一测量信息, 该第 一测量信息为该 UE对第一小区进行业务测量的信息, 该第一小区由 该第一基站提供服务。
其中, 0SS可以对基站、 UE进行管理和维护。
需要说明的是, ΜΝΤ 测量信息为 0SS确定 ΚΡΙ 下降原因时可能 需要的参数信息,由于该参数信息为第一基站收集的, 因此, 称为 ΜΝΤ测量信息。
S202、 OSS根据 MNT测量信息, 确定 KPI 下降原因。
0SS接收第一基站发送的 MNT 测量信息之后, 该 0SS 根据 MNT 测量信息, 确定 KPI 下降原因。
具体的, 0SS可以根据 MNT测量信息中的每一项 MNT测量信息, 分别确定 KPI 下降原因是哪项 MNT测量信息引起的。
本发明的实施例提供一种确定 KPI 下降原因的方法, 通过第一 基站接收 UE发送的业务消息, 该业务消息中夹带第一测量信息, 该 第一测量信息为该 UE对第一小区进行业务测量的信息, 该第一小区 由该第一基站提供服务, 并且该第一基站根据该业务消息, 获取该 第一测量信息, 以及该第一基站根据该第一测量信息, 生成 MNT 测 量信息, 最后, 该第一基站发送该 MNT 测量信息至 0SS。 通过该方 案, 由于第一基站可以通过 UE发送的业务消息, 最终生成 MNT测量 信息, 且第一基站可以发送该 MNT 测量信息至 0SS, 便于 0SS 确定 该 KPI 下降原因, 因此, 能够节省 UE上报开销, 保证 UE进行上行 业务的质量, 减少上报的测量信息对网络的冲击, 并提高了处理网 络问题的效率。
实施例二
本发明的实施例提供另一种确定 KPI 下降原因的方法, 如图 3 所示, 涉及 UE侧的确定 KPI 下降原因的方法, 该方法可以包括:
S301、 UE对第一小区进行 MDT ( Minimization of Drive Tests, 最小化路测) 测量, 并获取该 MDT 测量信息, 该第一小区由第一基 站提供服务。
需要说明的是, 本发明实施例提供的确定 KPI 下降原因的方法 的前提应用场景为: 当 0SS发现 KPI 下降时。 本发明实施例中的 UE 为可以进行 MDT测量的用户设备。
其中, KPI可以包括 5种类型的指标。
具体的,ΚΡΙ可以包括 RRC建立请求成功率、 RRC重建立成功率、 掉话率、 切换成功率及 E-RAB建立成功率。
需要说明的是, RRC建立请求成功率对应第一门限值、 RRC重建 立成功率对应第二门限值、 掉话率对应第三门限值、 切换成功率对 应第四门限值及 E-RAB建立成功率对应第五门限值, RRC建立请求 成功率低于第一门限值、 RRC 重建立成功率低于第二门限值、 掉话 率低于第三门限值、 切换成功率低于第四门限值或 E-RAB 建立成功 率低于第五门限值中的任意一项发生即为 0SS发现 ΚΡΙ 下降。 具体 的第一门限值、 第二门限值、 第三门限值、 第四门限值和第五门限 值的具体值的设定可以根据不同的运营商的实际情况而决定, 本发 明不作限制。
UE对第一小区进行 MDT测量, 并获取该 MDT测量信息, 其中, 该第一小区由第一基站提供服务。
需要说明的是, 在无线通信系统中, 小区由基站提供服务, 且 一个基站可以为多个小区提供服务。
S 302、 UE在业务间歇上报 MDT测量信息至第一基站, 该业务间 歇为该 UE传输业务数据的间隙。
UE对第一小区进行 MDT测量, 并获取该 MDT测量信息之后, 该 UE在业务间歇上报该 MDT测量信息至第一基站, 该业务间歇为该 UE 传输业务数据的间隙。
需要说明的是, MDT 测量信息为 0SS确定 KPI 下降原因时需要 的参数信息,由于该参数信息为 UE 测量并上报的, 因此, 称为 MDT 测量信息。
进一步地, UE在业务间隙上报 MDT测量信息至第一基站后, 由 该第一基站发送该 MDT测量信息至 0SS, 以使得 0SS可以根据该 MDT 测量信息, 确定 KPI 下降原因。
可以理解的是,由于 UE采用在业务间隙上报 MDT测量信息的方 式不占用 UE进行上行业务的信道的资源和时间, 且 UE在业务间隙 一次上报的 MDT测量信息的量不大, 因此, 能够节省 UE上报开销, 保证 UE进行上行业务的质量, 减少上报的测量信息对网络的冲击, 并提高了处理网络问题的效率。
示例性的, 假设 UE进行第一业务, 该 UE上报的第一业务为 A 和 B, 在 UE上报 A之后, 且在 UE上报 B之前, UE上报 MDT测量信 息至第一基站。
本发明的实施例提供另一种确定 KPI 下降原因的方法, 如图 4 所示, 涉及基站侧的确定 KPI 下降原因的方法, 该方法可以包括:

S402、 第一基站将 MDT测量信息发送至 0SS。
第一基站接收 UE在业务间歇上报的 MDT测量信息之后,该第一 基站将该 MDT测量信息发送至 0SS。
需要说明的是, 由于 0SS可以根据 MDT测量信息确定 KPI 下降 原因, 因此, 第一基站要讲 MDT 测量信息发送至 0SS, 以使得 0SS 可以根据该 MDT测量信息, 确定 KPI 下降原因。
本发明的实施例提供了另一种确定 KPI 下降原因的方法, 通过 UE对第一小区进行 MDT测量, 并获取 MDT测量信息, 该第一小区由 第一基站提供服务, 以及该 UE在业务间歇上报该 MDT测量信息至该 第一基站, 该业务间歇为该 UE传输业务数据的间隙。 通过该方案, 由于 UE采用在业务间隙上报 MDT测量信息的方式不占用 UE进行上 行业务的信道的资源和时间, 且 UE在业务间隙一次上报的 MDT测量 信息的量不大, 因此, 能够节省 UE上报开销, 保证 UE进行上行业 务的质量, 减少上报的测量信息对网络的冲击, 并提高了处理网络 问题的效率。
实施例三
本发明的实施例提供一种确定 KPI 下降原因的方法, 如图 5所 示, 该方法可以包括:

本发明实施例中, UE由第一基站由第一小区提供服务, 第一小 区由第一基站提供服务。 由于 UE 在进行某一业务时, UE 需要获知 UE所在小区, 即第一小区的业务测量的信息, 该第一小区的业务测 量的信息可以辅助 UE 进行该某一业务, 因此, UE 在进行某一业务 时发送的业务消息中夹带该第一小区的业务测量的信息。
需要说明的是, 本发明实施例中的 KP I 下降指的是运营商网络 的 KP I 下降。
本发明实施例提供的一种确定 K P I 下降原因的方法中, UE发送 业务消息至第一基站, 该业务消息中夹带第一测量信息, 该第一测 量信息为该 UE 进行业务时, UE 对第一小区进行业务测量的信息, 其中, 该第一小区由该第一基站提供服务。

需要说明的是, MNT 测量信息为 0 S S确定 KP I 下降原因时可能 需要的参数信息,由于该参数信息为第一基站收集的, 因此, 称为 MNT测量信息。
可以理解的是, 一方面, 由于第一基站可以获取第一测量信息, 并根据第一测量信息生成 MNT测量信息, 因此, UE不用再次专门上 报 0 S S确定 KP I 下降原因时需要的参数信息, 即 UE除了进行上行业 务的业务测量外, 不需要进行 MDT 测量, 并将该 MDT测量信息上报 至第一基站, 因此, 本发明实施例中, UE上报 MNT测量信息不占用 UE进行上行业务的信道资源和时间, 从而能够减少了 UE上报开销, 保证 UE进行上行业务的质量; 另一方面, 第一基站获取的第一测量 信息是夹带在 UE上报的业务消息中的, 因此, 第一基站不会一次性 接收大量的测量信息, 从而避免了上报测量信息对网络的冲击。

特别的, 第一预设阔值、 第二预设阔值、 第三预设阔值和第四 预设阔值的确定可以根据实际情况的不同而定, 本发明不作限制。
示例性的, 一种情况, 第一小区的信号强度为 -130dBm (分贝毫 伏), 第一预设阔值为 -90 dBm, 由于 -130小于- 90, 因此, 0SS确定 KPI 下降的原因为第一小区的信号强度弱。 另一种情况, 当 UE掉话, 或 UE 掉话完重新连接后, 第一小区的信号强度为 _130dBm, 第一预 设阔值为 -120 dBm, 由于 -130 小于 -120, 因此, 0SS确定 KPI 下降 的原因为第一小区中有信号漏洞。

其中, X2 可以实现基站间的相互连接, 即 X2 为第一基站与第 二基站间的接口。 具体的, 由于 X2 可以分为用户平面和控制平面, 因此, X2 接 口中的用户平面接口提供基站间的用户数据传输功能, X2接口中的 控制平面接口提供基站间的信令传输功能。
需要说明的是, 本发明实施例中, 第一基站的 X2 接口可以为 X2接口中的控制平面接口, 以使得该第一基站可以通过该第一基站 的 X2接口与第二基站进行信令交互。 第一基站的 X2接口也可以为 X2 接口中的用户平面接口, 以使得该第一基站可以通过该第一 X2 接口与第二基站进行数据传输。 具体的 X2接口类型的选择可根据实 际情况自行决定, 本发明不作限制。

特别的, 当 UE从第一小区切换到第二小区时, 若 UE切换失败, 即 0SS发现 KPI 下降时, 且无信号强度弱等问题, 则 0SS根据第一 小区的标识和第二小区的标识, 确定 KPI 下降原因是否为邻区管理 错误。
进一步地, 若确定 KPI 下降原因为邻区管理错误, 0SS 则可以 通过重新配置第一小区和第二小区为可切换的邻区, 从而解决 UE切 换失败的问题, 进而达到了网络优化的目的。
进一步地, 如图 7所示, 0SS确定 UE由第一小区提供服务时, 本发明实施例还提供一种确定 KPI 下降的方法, 该方法可以包括 S701-707, 具体如下:

可以理解的是,由于 UE采用在业务间隙上报 MDT测量信息的方 式不占用 UE进行上行业务的信道的资源和时间, 且 UE在业务间隙 一次上报的 MDT测量信息的量不大, 因此, 能够节省 UE上报开销, 保证 UE进行上行业务的质量, 减少上报的测量信息对网络的冲击, 并提高了处理网络问题的效率。
可选的, 业务间歇包括 CS业务的上行间歇及 PS业务的小包间 歇。 例如, CS业务间歇可以为语音业务、 传真业务的业务间歇等。 PS业务可以为浏览网页的业务间歇。

需要说明的是, MDT 测量信息为 0SS确定 KPI 下降原因时需要 的参数信息,由于该参数信息为 UE 测量并上报的, 因此, 称为 MDT 测量信息。
进一步地, UE在业务间隙通过发送上行数据上报 MDT测量信息 至第一基站后, 由该第一基站发送该 MDT 测量信息至 0SS, 以使得 0SS可以根据该 MDT测量信息, 确定 KPI 下降原因。
可以理解的是,由于 UE采用在业务间隙上报 MDT测量信息的方 式不占用 UE进行上行业务的信道的资源和时间, 且 UE在业务间隙 一次上报的 MDT测量信息的量不大, 因此, 能够节省 UE上报开销, 保证 UE进行上行业务的质量, 减少上报的测量信息对网络的冲击, 并提高了处理网络问题的效率。
可选的, 业务间歇包括 CS业务的上行间歇及 PS业务的小包间 歇。 例如, CS业务间歇可以为语音业务、 传真业务的业务间歇等。 PS业务可以为浏览网页的业务间歇。
示例性的, 假设 UE进行第一业务, 该 UE上报的第一业务为 A 和 B, 在 UE上报 A之后, 且在 UE上报 B之前, UE上报 MDT测量信 息至第一基站。
需要说明的是, 本发明实施例中, S802与 S803为 S801之后的 两个并列的步骤,故本发明实施例不限制在 S801之后, S802与 S803 的执行顺序, 即: 在 S801之后, 可以执行 S802, 也可以执行 S803。
S804、 第一基站将 MDT测量信息发送至 0SS。
第一基站接收 UE在业务间歇上报的 MDT测量信息之后,该第一 基站将该 MDT测量信息发送至 0SS。
需要说明的是, 由于 0SS可以根据 MDT测量信息确定 KPI 下降 原因, 因此, 第一基站要讲 MDT 测量信息发送至 0SS, 以使得 0SS 可以根据该 MDT测量信息, 确定 KPI 下降原因。
S805、 OSS 将 MDT 测量信息中的每一项测量信息和与该每一项 测量信息分别对应的预设阈值进行对比。
第一基站将 MDT测量信息发送至 0SS之后, 该 0SS将该 MDT测 量信息中的每一项测量信息和与该每一项测量信息分另 'J对应的预设 阔值进行对比。 需要说明的是, MDT 测量信息中包括多个参数信息, 且该 MDT 测量信息中的每一项测量信息分别对应一个预设阔值, 0SS 接收第 二基站发送的 MDT测量信息后, 该 0SS需将该 MDT测量信息中的每 一项测量信息与该每一项测量信息分另 'J对应的预设阈值进行对比, 从而确定 KPI 下降原因。
S806、 OSS 根据每一项测量信息和预设阔值的对比结果, 确定 KPI 下降原因。
0SS 将 MDT 测量信息中的每一项测量信息和与该每一项测量信 息分别对应的预设阔值进行对比, 该 0SS 根据该每一项测量信息和 预设阔值的对比结果, 确定 KPI 下降原因。
具体的, 若每一项测量信息中有至少一项测量信息分别不满足 与该至少一项测量信息对应的预设阔值, 0SS 则确定 KPI 下降原因 为该至少一项测量信息。
可选的, MDT 测量信息可以包括第一小区的信号强度和第一小 区的信号质量。
需要说明的是, 第一小区的信号强度对应的预设阔值为第一预 设阔值, 第一小区的信号质量对应的预设阔值为第二预设阔值。
具体的, 若符合第一小区的信号强度低于第一预设阔值和第一 小区的信号质量低于第二预设阔值中的至少一项, 0SS 则确定 KPI 下降原因为第一小区的信号强度和第一小区的信号质量中的至少一 个。
需要说明的是,若符合第一小区的信号强度低于第一预设阔值, 不符合第一小区的信号质量低于第二预设阔值, 0SS 则确定 KPI 下 降原因为第一小区的信号强度; 若符合第一小区的信号强度低于第 一预设阔值和第一小区的信号质量低于第二预设阔值, 0SS 则确定 KPI下降原因为第一小区的信号强度和第一小区的信号质量有问题。
特别的, 第一预设阔值和第二预设阔值的确定可以根据实际情 况的不同而定, 本发明不作限制。
示例性的, 一种情况, 第一小区的信号强度为 -130dBm (分贝毫 伏), 第一预设阔值为 -90 dBm, 由于 -130小于- 90, 因此, 0SS确定 KPI 下降的原因为第一小区的信号强度弱。 另一种情况, 当 UE掉话, 或 UE 掉话完重新连接后, 第一小区的信号强度为 _130dBm, 第一预 设阔值为 -120 dBm, 由于 -130 小于 -120, 因此, 0SS确定 KPI 下降 的原因为第一小区中有信号漏洞。
进一步地, 若第一小区的信号强度和第一小区的信号质量中有 至少一项测量信息分别不满足与至少一项测量信息对应的预设阔 值, 0SS 则确定 KPI 下降原因对应为第一小区的信号强度弱和第一 小区的信号质量差中的至少一个。
具体的, 若符合第一小区的信号强度低于第一预设阔值和第一 小区的信号质量低于第二预设阔值中的至少一项, 0SS 则确定 KPI 下降原因对应为第一小区的信号强度弱和第一小区的信号质量差中 的至少一个。
可选的, MDT测量信息还包括 UE的位置信息。
进一步地, 若第一小区的信号强度和第一小区的信号质量中有 至少一项测量信息分别不满足与该至少一项测量信, ¾对应的预设阔 值, 0SS 则根据 UE 的位置信息, 确定 KPI 下降原因对应为该 UE 所 在位置的第一小区的信号强度弱和该 UE 所在位置的第一小区的信 号质量差中的至少一个。
具体的, 若符合第一小区的信号强度低于第一预设阔值和第一 小区的信号质量低于第二预设阔值中的至少一项, 0SS则根据 UE的 位置信息, 确定 KPI 下降原因对应为该 UE所在位置的第一小区的信 号强度弱和该 UE所在位置的第一小区的信号质量差中的至少一个。
示例性的, UE在第一小区的位置 1处, 若符合第一小区的信号 强度低于第一预设阈值, 不符合第一小区的信号质量低于第二预设 阔值, PDCCH 的块误码率高于第三预设阔值及 PDSCH 的块误码率高 于第四预设阔值, 0SS则可根据 UE的位置信息, 确定 KPI 下降原因 为第一小区的位置 1 处的信号强度弱; 若符合第一小区的信号强度 低于第一预设阔值和第一小区的信号质量低于第二预设阔值, 0SS 则可根据 UE的位置信息, 确定 KPI 下降原因为第一小区的位置 1处 的信号强度弱和第一小区的位置 1处的信号质量差。
需要说明的是, MDT测量信息可以包括 UE通过 MDT测量得到的 所有参数信息, 0SS 可以根据该所有参数信息分析 KPI 下降原因, 故本发明不限制 MDT测量信息中具体的参数信息。
本发明的实施例提供了另一种确定 KPI 下降原因的方法, 通过 UE对第一小区进行 MDT测量, 并获取 MDT测量信息, 该第一小区由 第一基站提供服务, 以及该 UE在业务间歇上报该 MDT测量信息至该 第一基站, 该业务间歇为该 UE传输业务数据的间隙。 通过该方案, 由于 UE采用在业务间隙上报 MDT测量信息的方式不占用 UE进行上 行业务的信道的资源和时间, 且 UE在业务间隙一次上报的 MDT测量 信息的量不大, 因此, 能够节省 UE上报开销, 保证 UE进行上行业 务的质量, 减少上报的测量信息对网络的冲击, 并提高了处理网络 问题的效率。
