Abstract

本申请公开了一种PCI混淆检测的方法，所述方法包括：在基站获得测量小区的PCI和ECGI信息后，根据PCI和ECGI进行混淆检测，在ECGI不同时，若测量小区的PCI与所述服务小区的已配置邻区的PCI相同，则存在服务小区的未配置邻区与已配置邻区间的PCI混淆，在ECGI相同时，若测量小区的PCI与服务小区的其它已配置邻区的PCI相同，则存在服务小区的已配置邻区间的PCI混淆。本申请还公开了一种用户设备、基站。通过上述方式，本申请能够检测PCI混淆。

Description

PCI混淆检测的方法、用户设备及基站
【技术领域】
本申请涉及无线通讯技术领域，特别是涉及一种物理层小区标识（Physical Cell ID，PCI）混淆检测的方法、用户设备以及基站。
【背景技术】
PCI是长期演进 (Long Term Evolution，LTE)小区的物理标识，LTE一共有504个PCI（0~503），每个小区对应着一个PCI。PCI与信号同步、切换有关，当网络中的LTE小区相对较多时，不可避免地会出现PCI复用。若PCI复用隔离度相对较小，则会出现PCI混淆。
如图1所示，若用户设备检测到的小区Cell B202与服务小区Cell A201的已配置邻区Cell C203同频、同PCI，则导致PCI混淆。此时，PCI混淆有两种情况：
情况1：若Cell B202是Cell A201的已配置邻区，用户设备将Cell B202的PCI发送给Cell A201，Cell A201不知道用户设备发送的PCI是Cell B202的，还是Cell C203的，因此无法确定要切换的目标小区，从而不发起切换；
情况2：若Cell B202不是Cell A201的已配置邻区，用户设备将Cell B202的PCI发送给Cell A201，Cell A201以为用户设备测量到了Cell C203，并发起向Cell C203的切换。如图2所示，若用户设备位于Cell A201、Cell B202的交界处204、但该区域204没有Cell C203的覆盖，则此时用户设备切换到Cell C203时会发生切换掉话。

【具体实施方式】
下面结合附图和实施方式对本申请进行详细说明。
参阅图2，图2是本申请物理层小区标识PCI混淆检测的方法一实施方式的流程图，本实施方式是基站进行PCI混淆检测的流程图，该流程图包括：
步骤S201：服务小区所属的基站从第一用户设备获得包含测量小区的物理层小区标识（Physical Cell ID，PCI）的信息的测量报告，测量小区至少包括一个小区；
服务小区是向用户设备提供服务的小区。
广义的基站是基站子系统（BSS，Base Station Subsystem）的简称。以全球移动通信系统（GSM，Global System for Mobile Communications）网络为例，包括基站收发信机（BTS）和基站控制器（BSC）。一个基站控制器可以控制十几以至数十个基站收发信机。在宽带码分多址（WCDMA，Wideband Code Division Multiple Access）等系统中，类似的概念称为Node B和无线网络控制器（RNC）。Evolved Node B是演进型Node B，是LTE网络中基站的名称，相比现有3G中的Node B，它集成了部分RNC的功能，减少了协议的层次。
PCI，物理小区标识，用来区分来自不同LTE小区的信号，通过中心频点和PCI可以区分不同的小区，而且PCI还会直接影响到小区中公共信道等的加扰或者发送位置以及下行同步。
步骤S202：基站从第一用户设备获得包含测量小区的E-UTRAN小区全球标识（E-UTRAN cell global identifier，ECGI）的信息；
ECGI是LTE小区全球标识，只要LTE小区的ECGI不一样，就属于不同的LTE小区，如果LTE小区的某两个ECGI相同，则属于同一个LTE小区。
步骤S203：若判断所述测量小区的ECGI与所述服务小区的已配置邻区的ECGI不相同，且所述测量小区的PCI与所述服务小区的已配置邻区的PCI相同，则存在所述服务小区的未配置邻区与所述已配置邻区间的PCI混淆，和/或，若判断所述测量小区的ECGI与所述服务小区的已配置邻区的ECGI相同，且所述测量小区的PCI与所述服务小区的其它已配置邻区的PCI相同，则存在所述服务小区的所述已配置邻区间的PCI混淆。
关于PCI混淆的原理可以参见图1。如果测量小区的ECGI与服务小区的已配置邻区的ECGI不相同，表明测量小区是服务小区的未配置邻区，判断测量小区的PCI与服务小区的已配置邻区的PCI是否相同，可以检测出是否存在服务小区的未配置邻区与已配置邻区间的PCI混淆，如果测量小区的PCI与服务小区的已配置邻区的PCI相同，表明存在服务小区的未配置邻区与已配置邻区间的PCI混淆。
如果测量小区的ECGI与服务小区的已配置邻区的ECGI相同，表明测量小区是服务小区的已配置邻区中的其中一个已配置邻区，如果测量小区的ECGI与服务小区的已配置邻区的ECGI相同，且与服务小区的其它已配置邻区的PCI相同，表明存在服务小区的已配置邻区间的PCI混淆。
在检测到存在服务小区的未配置邻区与已配置邻区间的PCI混淆和/或存在服务小区的已配置邻区间的PCI混淆时，可以上报网管，以便于网管做出调整和布局。
本申请实施方式由基站获得ECGI和PCI后，通过ECGI和PCI即可判断是否存在PCI混淆，特别是在测量小区的ECGI与服务小区的已配置邻区的ECGI不相同时，表明测量小区是服务小区的未配置邻区，如果此时该测量小区的PCI与服务小区的已配置邻区的PCI相同，表明存在服务小区的未配置邻区与已配置邻区间的PCI混淆，是“未配置邻区”的测量小区与服务小区的“已配置邻区”的PCI混淆。通过上述方式，能够检测PCI混淆，而且能够检测“未配置邻区”与“已配置邻区”间的PCI混淆。
参阅图3，图3是本申请物理层小区标识PCI混淆检测的方法另一实施方式的流程图，本实施方式是包括基站和用户设备在内的进行PCI混淆检测的流程图，该流程图具体包括：
步骤S301：服务小区所属的基站向第一用户设备发送第一测量配置消息，第一测量配置消息用于请求第一用户设备进行小区测量并上报测量得到的包含测量小区的PCI的信息的测量报告，测量小区至少包括一个小区；
进行小区测量即为对网络侧的预定频点进行测量，并上报包括测量小区的PCI在内的信息的测量报告。
在LTE网络中，用户设备进行测量时，都是按频点进行测量的，例如网络中是频点f，那么用户设备会测量网络中f频点的所有小区。
网络侧主要指无线网络控制器（RNC）和核心网（CN），又称C侧，主要是一些分组域的核心网。
服务小区所属的基站向第一用户设备发送第一测量配置消息，请求第一用户设备对网络侧的预定频点进行测量并上报包括测量小区的PCI在内的信息的测量报告，且测量小区至少包括一个小区。
PCI，物理小区标识，用来区分来自不同LTE小区的信号，通过中心频点和PCI可以区分不同的小区，而且PCI还会直接影响到小区中公共信道等的加扰或者发送位置以及下行同步。
步骤S302：第一用户设备在接收第一测量配置消息后，对小区进行测量，即对网络侧的预定频点进行针对预定测量参数的测量，得到测量报告；
例如网络中是频点f，那么第一用户设备会测量网络中f频点的所有小区进行针对第一测量配置消息中的预定测量参数的测量。
步骤S303：第一用户设备向基站发送测量得到的包含测量小区的PCI在内的信息的测量报告；
获得测量报告后，第一用户设备向基站发送包括测量小区的PCI在内的信息的测量报告。
步骤S304：基站接收第一用户设备的测量报告后，向第一用户设备发送第二测量配置消息，第二测量配置消息用于请求第一用户设备将与已接收的PCI对应的测量小区的包括ECGI在内的信息进行上报；
基站接收第一用户设备的测量报告后，向第一用户设备发送第二测量配置消息，请求第一用户设备将与已接收的PCI对应的测量小区的包括ECGI在内的信息进行上报。ECGI是LTE小区全球标识，只要LTE小区的ECGI不一样，就属于不同的LTE小区，如果LTE小区的某两个ECGI相同，则属于同一个LTE小区。
步骤S305：第一用户设备接收基站的第二测量配置消息后，向基站发送从测量小区的广播中读取的与已发送的测量小区的PCI对应的包括ECGI在内的信息；
第一用户设备接收基站的第二测量配置消息后，从测量小区的广播中读取包含测量小区的ECGI的信息，向基站发送与已发送的测量小区的PCI对应的包括ECGI在内的信息。
步骤S306：基站接收第一用户设备的测量小区的包括ECGI在内的信息后，根据已接收的包括测量小区的PCI的测量报告和测量小区的ECGI，判断测量小区的ECGI与服务小区的已配置邻区的ECGI是否相同；如果与服务小区的已配置邻区的ECGI不相同，进入步骤S307，如果与服务小区的已配置邻区的ECGI相同，进入步骤S309。
基站接收测量小区的包括ECGI在内的信息后，根据已接收的包括测量小区的PCI的测量报告和测量小区的ECGI，可以判断测量小区与服务小区的已配置邻区的ECGI是否相同。
邻区是指两个信号覆盖有重叠并设置有切换关系的小区，一个小区可以有多个相邻小区。简单的说就是使用户设备在移动状态下可以在多个定义了邻区关系的小区之间进行业务的平滑交替，不会中断。只有添加了邻区，用户设备才能在不同小区之间进行切换。
步骤S307：若与服务小区的已配置邻区的ECGI不相同，则判断测量小区的PCI与服务小区的已配置邻区的PCI是否相同；
如果测量小区的ECGI与服务小区的已配置邻区的ECGI不相同，表明测量小区是服务小区的未配置邻区，判断测量小区的PCI与服务小区的已配置邻区的PCI是否相同，可以检测出是否存在所述服务小区的未配置邻区与所述已配置邻区间的PCI混淆。
步骤S308：若与服务小区的已配置邻区的PCI相同，则判断为存在所述服务小区的未配置邻区与所述已配置邻区间的PCI混淆；
如果测量小区的PCI与服务小区的已配置邻区的PCI相同，表明存在所述服务小区的未配置邻区与所述已配置邻区间的PCI混淆。
步骤S309：若与服务小区的已配置邻区的ECGI相同，则基站将与测量小区具有相同ECGI的已配置邻区的PCI更新，使其更新为已接收的测量小区的PCI，已接收的测量小区的PCI与服务小区的已配置邻区的ECGI相同，并判断更新后的已配置邻区的PCI与服务小区的其它已配置邻区的PCI是否相同；
如果测量小区的ECGI与服务小区的已配置邻区的ECGI相同，表明测量小区是服务小区的已配置邻区中的其中一个已配置邻区，且该服务小区的已配置邻区对应的PCI已经发生了变化，但是该已配置邻区在在服务小区所属的基站中保存的信息还是以前的，服务小区所属的基站将与测量小区具有相同ECGI的已配置邻区的PCI更新，使其更新为已接收的测量小区的PCI，其中，已接收的测量小区的PCI与服务小区的已配置邻区的ECGI相同，然后判断更新后的已配置邻区的PCI与服务小区的其它已配置邻区的PCI是否相同，检测是否存在所述服务小区的所述已配置邻区间的PCI混淆。
步骤S310：若与服务小区的其它已配置邻区的PCI相同，则判断为存在所述服务小区的所述已配置邻区间的PCI混淆。
如果更新后的已配置邻区的PCI与服务小区的其它已配置邻区的PCI相同，表明存在所述服务小区的所述已配置邻区间的PCI混淆。
在检测到存在服务小区的未配置邻区与已配置邻区间的PCI混淆和/或存在服务小区的已配置邻区间的PCI混淆时，可以上报网管，以便于网管做出调整和布局。
本申请实施方式由基站来直接向第一用户设备要求先后提供包括测量小区的PCI和ECGI的信息，在基站获得ECGI和PCI后，在测量小区的ECGI与服务小区的已配置邻区的ECGI不相同时，表明测量小区是服务小区的未配置邻区，如果此时该测量小区的PCI与服务小区的已配置邻区的PCI相同，表明存在服务小区的未配置邻区与已配置邻区间的PCI混淆，是“未配置邻区”的测量小区与服务小区的“已配置邻区”的PCI混淆。通过上述方式，能够检测PCI混淆，而且能够检测“未配置邻区”与“已配置邻区”间的PCI混淆。
参阅图4，图4是本申请物理层小区标识PCI混淆检测的方法又一实施方式的流程图，本实施方式是基站进行PCI混淆检测的流程图，该流程图包括：
第一部分过程：服务小区所属的基站从第一用户设备获得包含测量小区的PCI的信息的测量报告，测量小区至少包括一个小区；该部分流程包括如下步骤：
步骤S401包括步骤S401a和步骤S401b，具体内容如下：
步骤S401a：基站根据预先设置的进行PCI混淆检测的时间范围条件，判断目前时间是否符合进行PCI混淆检测的时间范围条件，PCI混淆检测的时间范围条件包括PCI混淆检测的开关、PCI混淆检测的起始时间或PCI混淆检测的结束时间中的至少一项；
例如：1、仅当“PCI混淆检测的开关”在开启时，且处于PCI混淆检测的起始时间和PCI混淆检测的结束时间段之间，基站才进行步骤S401b；2、若“PCI混淆检测的开关”在关闭时、或到达PCI混淆检测的结束时间段，则基站结束PCI混淆检测，并停止相应的测量；3、若 “PCI混淆检测的开关”在开启时，则基站每天在PCI混淆检测的起始时间、PCI混淆检测的结束时间进行PCI混淆检测，即以天为单位自动进行PCI混淆检测，进入步骤S401b；4、仅仅设置PCI混淆检测的开关、PCI混淆检测的起始时间或PCI混淆检测的结束时间三个参数中的一个或两个。总之，这三个参数的设置可以精确到基站的粒度，用于限定PCI混淆检测的操作时间与操作范围。
步骤S401b：若符合进行PCI混淆检测的时间范围条件，则服务小区所属的基站发送指令，指令要求向选中的第一用户设备发送第一测量配置消息。如果符合所述进行PCI混淆检测的时间范围条件，进入步骤S404。
由于第一用户设备在进行邻区测量、ECGI的读取时，会消耗空口资源。因此，通过检测开关和时间段控制，可以减小PCI混淆检测对网络的影响。
值得一提的是，步骤S401是对PCI混淆检测的时间范围进行了控制，在实际应用中，此步骤也可以省略，直接进入步骤S404。
步骤S402包括步骤S402a和步骤S402b，具体内容如下：
步骤S402a：基站根据预先设置的选择第一用户设备的条件，判断服务小区中的第一用户设备是否符合所述条件，预先设置的选择第一用户设备的条件包括第一用户设备的能级、第一用户设备的状态、第一用户设备参与PCI混淆检测的预定次数、参与PCI混淆检测的第一用户设备的预定数量中至少一项；
例如：通过第一用户设备的能级进行选择时，可以选择支持ECGI测量的用户设备；通过第一用户设备的状态进行选择时，可以选择新接入的用户设备或者新呼叫的用户设备、非切换接入的用户设备或非无线资源控制(radio resource control，RRC)重建接入的用户设备等；通过预先设置参与PCI混淆检测的测量的第一用户设备的数量来进行选择；或者预先设置每个选中的第一用户设备参与PCI混淆检测的次数。当然，也可以将上述四项进行组合，以便于选择第一用户设备。
步骤S402b：若符合条件，则服务小区中的用户设备即为选中的第一用户设备。步骤S402b操作完毕，进入步骤S404。
由于第一用户设备进行邻区测量、ECGI的读取会消耗空口资源，基站处理管理测量信息，也会占用基站自己的资源。因此，有针对性地选择进行PCI混淆检测的用户设备，可以减少PCI混淆检测对资源的占用以及对网络的影响。
需要说明的是，步骤S402有针对性的选择进行PCI混淆检测的第一用户设备，限制了参与测量的第一用户设备数量，在不需要特别选择第一用户设备时，可以直接进入步骤S404。
步骤S403：基站设置第一用户设备测量报告机制；步骤S403具体包括：基站设置第一测量配置消息所对应的第一用户设备上报测量报告的触发条件，触发条件使得第一用户设备在切换前已向基站发送第一测量配置消息的测量报告，使PCI混淆在切换前就被发现并解决，例如：减小A3Offset、A4Threshold等。。步骤S403操作完毕，进入步骤S404。在不需要设置第一用户设备上报测量报告的触发条件时，直接进入步骤S404。
进一步地，步骤S403还包括：基站设置第一测量配置消息所对应的第一用户设备上报测量报告的预定上报次数与第一用户设备上报测量报告的间隔周期。
第一用户设备上报测量报告的预定上报次数与第一用户设备上报测量报告的间隔周期是对第一用户设备上报测量报告的行为进行控制，通过设置第一用户设备上报测量报告的预定上报次数与用户设备上报测量报告的间隔周期，可以减少第一用户设备和基站的资源消耗。
需要说明的是，步骤S401、步骤S402以及步骤S403没有先后顺序关系，在实际应用中，步骤S401、步骤S402以及步骤S403也可以根据实际应用要求，选择其中的一个步骤、两个步骤或者两个以上的步骤进行操作。
步骤S404：服务小区所属的基站向选中的第一用户设备发送第一测量配置消息，第一测量配置消息用于请求用户设备进行小区测量并上报测量得到的包含测量小区的PCI的信息的测量报告，测量小区至少包括一个小区；
进行小区测量即为对网络侧的预定频点进行测量并上报包括测量小区的PCI在内的信息的测量报告；
服务小区所属的基站向选中的第一用户设备发送第一测量配置消息，是请求用户设备对网络侧的预定频点进行测量并上报包括测量小区的PCI在内的信息的测量报告。
服务小区是向用户设备提供服务的小区。在LTE网络中，用户设备进行测量时，都是按频点进行测量的，例如网络中是频点f，那么用户设备会测量网络中f频点的所有小区。
其中，步骤S404具体是：服务小区所属的基站向选中的第一用户设备发送第一测量配置消息，第一测量配置消息用于请求第一用户设备对网络侧的预定频点进行测量并上报包括预定数量的测量小区的PCI在内的信息的测量报告。
此步骤在第一测量配置消息中对测量小区的数量进行了限制，因为第一用户设备进行测量会消耗资源，基站也会消耗资源，对测量小区的数量进行了限制，可以减少资源的消耗。例如：将测量小区的预定数量设置为1，只让用户设备上报最优邻小区，即最可能发生PCI混淆的测量小区。
进一步地，步骤S404具体是：服务小区所属的基站向选中的第一用户设备发送第一测量配置消息，第一测量配置消息用于请求第一用户设备对网络侧的预定频点进行测量、并上报包括测量小区的PCI在内的信息的测量报告以及用户设备上报测量报告的触发条件。
在基站设置了第一用户设备上报测量报告的触发条件后，向选中的第一用户设备发送的第一测量配置消息也就包括了第一用户设备上报测量报告的触发条件，通过这种方式，使PCI混淆在切换前就被发现并解决，可以保证网络的正常切换。
进一步地，步骤S404具体是：服务小区所属的基站向选中的第一用户设备发送第一测量配置消息，所述第一测量配置消息是请求第一用户设备对网络侧的预定频点进行测量、并上报包括测量小区的PCI在内的信息的测量报告、第一用户设备上报测量报告的触发条件以及第一用户设备上报测量报告的预定上报次数与第一用户设备上报测量报告的间隔周期的消息。
第一用户设备上报测量报告的预定上报次数与第一用户设备上报测量报告的间隔周期是对第一用户设备上报测量报告的行为进行控制，通过设置第一用户设备上报测量报告的预定上报次数与第一用户设备上报测量报告的间隔周期，可以减少第一用户设备和基站的资源消耗。
步骤S405包括步骤S405a、步骤S405b以及步骤S405c，具体内容如下：
步骤S405a：基站设置测量定时器的时间长度；
步骤S405b：判断在测量定时器的时间长度内，是否接收到来自所述第一用户设备的测量报告；
步骤S405c：若没有接收到来自所述第一用户设备的测量报告，则向第一用户设备发送停止测量的指令。
因为第一用户设备进行测量会消耗资源，基站也会消耗资源，若在一定时间内，第一用户设备仍然没有上报相应的测量报告，则让第一用户设备中止相应的测量，通过这种方式，可以减少资源的消耗。
其中，步骤S405对第一用户设备的测量行为进行了控制，在实际应用中，没有步骤S405时，直接进入步骤S407。
步骤S406包括步骤S406a、步骤S406b以及步骤S406c，具体内容如下：
步骤S406a：基站设置接收来自第一用户设备的测量报告的次数为预定接收次数；
步骤S406b：判断接收来自第一用户设备的测量报告的次数是否已经达到预定接收次数；
步骤S406c：若已经达到预定接收次数，则向第一用户设备发送停止测量的指令。
其中，步骤S406对第一用户设备的测量行为进行了控制，步骤S406a可以在步骤S407之前进行，也可以在步骤S407之后进行，步骤S406b和步骤S406c是在步骤S407之后进行。在实际应用中，没有步骤S406时，直接进入步骤S407。
第一用户设备进行测量会消耗资源，基站也会消耗资源，若预先设置测量报告的上报次数，例如，若测量小区信号满足第一用户设备上报测量报告的触发条件，则测量报告转为周期性做一次测量上报，通过这种方式，可以减少资源的消耗。
需要说明的是，在实际应用中，步骤S405和步骤S406两个步骤可以择一操作，也可以两个步骤都操作。步骤S405和步骤S406都是基站对第一用户设备的测量行为的控制，可以减少资源浪费。
步骤S407：基站向第一用户设备发送第一测量配置消息后，接收来自第一用户设备的测量报告，测量报告中包括测量小区的PCI的信息；
在基站向第一用户设备发送第一测量配置消息后，如果第一用户设备向基站发送测量报告，则基站接收来自第一用户设备的测量报告，测量报告中包括测量小区的PCI的信息。
步骤S408：基站在接收来自第一用户设备的测量报告后，向第一用户设备发送停止测量的指令；
步骤S408具体为：基站在接收来自第一用户设备的测量报告后，删除测量报告对应的测量标识，并向第一用户设备发送停止该测量标识对应的测量的指令。
通过步骤S408，可以减少资源的消耗和浪费。
第二部分过程：基站从第一用户设备获得包含测量小区的ECGI的信息；该过程包括如下步骤：
步骤S409：基站接收来自第一用户设备的测量报告后，向第一用户设备发送第二测量配置消息，第二测量配置消息用于请求第一用户设备将与已接收的测量小区的PCI对应的包括ECGI在内的信息进行上报；
ECGI是LTE小区全球标识，只要LTE小区的ECGI不一样，就属于不同的LTE小区，如果LTE小区的某两个ECGI相同，则属于同一个LTE小区。
步骤S410：基站向第一用户设备发送第二测量配置消息后，接收来自第一用户设备的测量小区的包括ECGI在内的信息；
第三部分过程：若判断测量小区的ECGI与所述服务小区的已配置邻区的ECGI不相同，且所述测量小区的PCI与服务小区的已配置邻区的PCI相同，则存在所述服务小区的未配置邻区与所述已配置邻区间的PCI混淆，或者，若判断测量小区的ECGI与服务小区的已配置邻区的ECGI相同，且所述测量小区的PCI与服务小区的其它已配置邻区的PCI相同，则存在所述服务小区的所述已配置邻区间的PCI混淆；该过程包括如下步骤：
步骤S411：基站根据已接收的包括测量小区的PCI的测量报告和测量小区的ECGI，判断测量小区的ECGI与服务小区的已配置邻区的ECGI是否相同；如果与服务小区的已配置邻区的ECGI不相同，进入步骤S412，如果与服务小区的已配置邻区的ECGI相同，进入步骤S414。
步骤S412：若与服务小区的已配置邻区的ECGI不相同，则判断测量小区的PCI与服务小区的已配置邻区的PCI是否相同；
步骤S413：若与服务小区的已配置邻区的PCI相同，则存在所述服务小区的未配置邻区与所述已配置邻区间的PCI混淆。
步骤S414：若与服务小区的已配置邻区的ECGI相同，则基站将与测量小区具有相同ECGI的已配置邻区的PCI更新，使其更新为已接收的测量小区的PCI，已接收的测量小区的PCI与所述服务小区的已配置邻区的ECGI相同，并判断更新后的已配置邻区的PCI与服务小区的其它已配置邻区的PCI是否相同；
步骤S415：若与服务小区的其它已配置邻区的PCI相同，则存在所述服务小区的所述已配置邻区间的PCI混淆。
在检测到存在服务小区的未配置邻区与已配置邻区间的PCI混淆和/或存在服务小区的已配置邻区间的PCI混淆时，可以上报网管，以便于网管做出调整和布局。
总之，本申请实施方式由基站来直接向第一用户设备要求先后提供包括测量小区的PCI和ECGI的信息，在基站获得ECGI和PCI后，在测量小区的ECGI与服务小区的已配置邻区的ECGI不相同时，表明测量小区是服务小区的未配置邻区，如果此时该测量小区的PCI与服务小区的已配置邻区的PCI相同，表明存在所述服务小区的未配置邻区与所述已配置邻区间的PCI混淆。通过上述方式，能够检测PCI混淆，而且能够检测“未配置邻区”与“已配置邻区”间的PCI混淆。
另外，通过检测开关和时间段控制，可以减小PCI混淆检测对网络的影响；有针对性地选择进行PCI混淆检测的用户设备，可以减少PCI混淆检测对资源的占用以及对网络的影响；通过设置用于PCI混淆检测的第一测量配置消息所对应的用户设备上报测量报告的触发条件，使PCI混淆在切换前就被发现并解决；通过对用户设备的测量行为的控制，可以减少资源浪费。

步骤S51：第一用户设备获得包含测量小区的PCI的信息的测量报告，并向基站发送测量报告，测量小区至少包括一个小区；
第一用户设备通过测量即可获得包含测量小区的PCI的信息的测量报告，然后将获得的测量报告向基站发送，其中，测量小区至少包括一个小区。
步骤S52：第一用户设备获得包含测量小区的ECGI的信息，并向基站发送包含测量小区的ECGI的信息。
在向基站发送包含测量小区的PCI的信息的测量报告后，从广播中即可获得包含测量小区的ECGI的信息，然后向基站发送包含测量小区的ECGI的信息。
本申请实施方式由用户设备向基站先后发送包括测量小区的PCI和ECGI的信息，在基站获得ECGI和PCI后，可以判断是否存在PCI混淆。通过上述方式，能够检测PCI混淆。在检测到存在服务小区的未配置邻区与已配置邻区间的PCI混淆和/或存在服务小区的已配置邻区间的PCI混淆时，可以上报网管，以便于网管做出调整和布局。

进行小区测量即为对网络侧的预定频点进行测量并上报包括测量小区的PCI在内的信息的测量报告；
其中，步骤S501具体包括：第一用户设备接收来自基站的第一测量配置消息，第一测量配置消息是请求用户设备对网络侧的预定频点进行测量、并上报包括测量小区的PCI在内的的信息的测量报告以及用户设备上报测量报告的触发条件的消息。
进一步地，步骤S501具体包括：第一用户设备接收来自基站的第一测量配置消息，所述第一测量配置消息是请求第一用户设备对网络侧的预定频点进行测量、并上报包括测量小区的PCI在内的信息的测量报告、第一用户设备上报测量报告的触发条件或第一用户设备上报测量报告的预定上报次数与第一用户设备上报测量报告的间隔周期的消息。第一测量配置消息用于请求所述第一用户设备进行小区测量并上报测量得到的包含预定数量的测量小区的PCI的信息的测量报告。
步骤S502：第一用户设备在接收来自基站的第一测量配置消息后，对网络侧的预定频点进行针对预定测量参数的测量；如果获得测量报告，进入步骤S504，如果在测量过程中，没有获得测量报告，且基站向第一用户设备发送停止测量的指令，则第一用户设备接收来自基站的停止测量的指令，并停止所述测量。
例如网络中是频点f，那么用户设备会测量网络中f频点的所有小区进行针对第一测量配置消息中的预定测量参数的测量。
在步骤S501的第一测量配置消息中包括第一用户设备上报测量报告的触发条件时，第一用户设备需要执行步骤S503，如果第一测量配置消息中不包括第一用户设备上报测量报告的触发条件，第一用户设备不需要执行步骤S503。
步骤S503包括步骤S503a和步骤S503b，具体内容如下：
步骤S503a：第一用户设备根据已接收的第一用户设备上报测量报告的触发条件，判断获得的测量信息是否符合第一用户设备上报测量报告的触发条件；
步骤S503b：若符合第一用户设备上报测量报告的触发条件，则第一用户设备向基站发送所述获得的测量报告。
步骤S503b可以具体为：若符合第一用户设备上报测量报告的触发条件，则第一用户设备发送内部指令，指令要求第一用户设备向基站发送所述获得的测量报告。
在测量信息不符合第一用户设备上报测量报告的触发条件时，第一用户设备一直进行测量，在测量过程中，如果基站向第一用户设备发送停止测量的指令，则第一用户设备接收来自基站的停止测量的指令，并停止所述测量。在测量过程中，如果测量信息符合第一用户设备上报测量报告的触发条件，则进入步骤S504。
步骤S504：第一用户设备向基站发送包括测量小区的PCI在内的信息的测量报告；
如果在步骤S501的第一测量配置消息中包括第一用户设备上报测量报告的触发条件、第一用户设备上报测量报告的预定上报次数与第一用户设备上报测量报告的间隔周期时，用户设备除了执行步骤S503外，还需要执行步骤S505，如果第一测量配置消息中不包括第一用户设备上报测量报告的预定上报次数与第一用户设备上报测量报告的间隔周期，用户设备不需要执行步骤S505，直接进入步骤S506。
步骤S505包括步骤S505a、步骤S505b以及步骤S505c，具体内容如下：
步骤S505a：第一用户设备根据已接收的所述第一用户设备上报测量报告的预定上报次数，判断测量报告上报的次数是否达到预定上报次数；
步骤S505b：若测量报告上报的次数没有达到预定上报次数，则第一用户设备根据已接收的第一用户设备上报测量报告的间隔周期，再次向基站发送所述测量报告，并返回所述步骤S505a；
步骤S505c：若测量报告上报的次数达到预定上报次数，则第一用户设备停止向基站发送所述测量报告。
例如，若测量信息满足第一用户设备上报测量报告的触发条件，则上报测量报告事件转周期做一次测量上报，达到预定上报次数后，停止上报。
第一用户设备上报测量报告的预定上报次数与第一用户设备上报测量报告的间隔周期是对第一用户设备上报测量报告的行为进行控制，可以减少第一用户设备和基站的资源消耗。
第二部分过程：第一用户设备获得包含所述测量小区的ECGI的信息，并向所述基站发送包含所述测量小区的ECGI的信息。该过程包括如下步骤：
步骤S506：第一用户设备在向基站发送包括测量小区的PCI在内的的信息的测量报告后，接收来自基站的第二测量配置消息，第二测量配置消息是请求第一用户设备将与已发送的测量小区的PCI对应的包括ECGI在内的信息进行上报的消息；进入步骤S507。
需要说明的是，步骤S505和步骤S506没有明显的先后顺序关系，一般在步骤S504之后，第一用户设备就会执行步骤S505，执行步骤S506取决于基站是否向第一用户设备发送第二测量配置消息。
其中，在步骤S504之后的过程中，如果基站向第一用户设备发送停止测量的指令，则第一用户设备接收来自基站的停止测量的指令，并停止测量及测量上报，具体过程可以是：在步骤S504之后的过程中，如果基站向第一用户设备发送停止已发送的测量报告对应的测量ID所对应的测量的指令，则第一用户设备接收来自基站的停止已发送的测量报告对应的测量ID所对应的测量的指令，并停止所述测量ID对应的测量及测量上报。
步骤S507：第一用户设备在接收基站的第二测量配置消息后，向基站发送从测量小区的广播中读取的与已发送的测量小区的PCI对应的包括ECGI在内的信息。
总之，本申请实施方式由用户设备向基站先后提供包括测量小区的PCI和ECGI的信息，在基站获得ECGI和PCI后，可以判断是否存在PCI混淆。通过上述方式，能够检测PCI混淆。在检测到存在服务小区的未配置邻区与已配置邻区间的PCI混淆和/或存在服务小区的已配置邻区间的PCI混淆时，可以上报网管，以便于网管做出调整和布局。
