LTE系统事件简介一、LTE事件概述LTE切换时需要UE上报测量的结果（包括RSRP，RSRQ等），而上报又分为周期性上报和事件触发的上报。
➢周期性上报由基站配置，UE直接上报测量的结果。
➢事件触发的上报又分为系统内的事件和系统间的事件。
LTE系统内切换主要事件包括：➢A1事件，服务小区质量高于门限；这个事件可以用来关闭频间测量。
➢A2事件，服务小区质量低于门限；这个事件可以用来打开频间测量和系统间测量，因为这个事件发生后可能发生切换等操作。
➢A3事件，邻小区质量好于服务小区质量；这个事件一般用于频内/间基于覆盖的切换。
➢A4事件，邻小区质量好于门限；这个事件一般用于基于负荷的切换。
➢A5事件，服务小区质量低于一个门限并且邻小区质量高于一个门限；这个事件也可以用于频内/间基于覆盖的切换。

LTE测量与切换详解（非常全面）1 测量过程测量过程主要包括以下三个步骤：测量配置：由eNB通过RRCConnectionReconfigurtion消息携带的measConfig信元将测量配置消息通知给UE，即下发测量控制。
测量执行：UE会对当前服务小区进行测量，并根据RRCConnectionReconfigurtion消息中的s-Measure信元来判断是否需要执行对相邻小区的测量。
测量报告：测量报告触发方式分为周期性和事件触发。
当满足测量报告条件时，UE将测量结果填入MeasurementReport消息，发送给eNB。
1.1 测量配置测量配置主要由eNB通过RRCConnectionReconfigurtion消息携带的measConfig信元将测量配置消息通知给UE，包含UE需要测量的对象、小区列表、报告方式、测量标识、事件参数等。
当测量条件改变时，eNB通知UE新的测量条件。
●触发条件：eNB向UE发起/修改/删除测量。
●发送网元：（eNB）处理：将测量配置填项填入RRCConnectionReconfigurtion消息中的measConfig信元。
●接收网元（UE）处理：UE侧维护一个测量配置数据库VarMeasConfig，在VarMeasConfig 中，每个measId对应一个measObjectId和一个reportConfigId。
其中，measId是数据库测量配置条目索引；measObjectId是测量对象标识，对应一个测量对象配置项；reportConfigId是测量报告标识，对应一个测量报告配置项。
此外还包含了与measId无关的公共配置项quantityConfig、测量量配置、s-Measure和服务小区质量门限控制等。
Measurement objects（测量对象）：UE测量的对象如下●对于频率内和频率间的测量，测量对象是一个单一的E-UTRA承载频率。

lte小区切换案例LTE小区切换是指终端设备在从一个小区移动到另一个小区时，需要重新选择和连接新的小区，以确保通信的稳定和流畅。
在实际应用中，LTE小区切换质量直接关系到通信质量和用户体验。
下面我们来分步骤阐述LTE小区切换案例。
第一步，建立初始连接。
在终端设备上，首先要建立初始连接，即与初始小区建立通信。
设备发送“RRC Connection Request”消息进行请求，小区收到请求后，发送“RRC Connection Setup”消息建立连接，并给终端设备分配临时标识TMSI，之后发送“RRC Connection Complete”消息确认连接建立成功。
第二步，进行切换准备。
当设备检测到信号质量较低或无信号时，便开始进行小区切换准备。
设备发送“Measurement Report”消息给初始小区，通知其该设备已经开始准备切换，并开始在周围其他小区中进行测量，选择信号质量较好的小区。
第三步，选择目标小区。
设备通过测量报告自主选择信号质量较好的目标小区，并发送“Handover Request”消息给初始小区，请求切换到目标小区。
初始小区收到请求后，进行“Handover Preparation”准备工作，包括与目标小区通信、资源分配等。
第四步，执行小区切换。
当初始小区已经做好了切换准备，便发送指令消息给终端设备，要求其切换至目标小区。
设备接收到消息后，开始断开与初始小区的连接，并发送“Handover Command”消息通知目标小区要求连接。
第五步，完成小区切换。
目标小区收到“Handover Command”消息后，开始分配资源，并发送“Handover Request Acknowledge”消息通知切换成功。
设备接收到消息后，发送“Handover Complete”消息，确认切换成功。
总体来说，LTE小区切换需要经过建立初始连接、切换准备、选择目标小区、执行小区切换、完成小区切换等多个步骤。

1.MR是什么MR就是measurement report，手机报上来的测量报告，网优可以根据这个确定某些片区的覆盖情况测量是TD-LTE系统的一项重要功能，针对大量测量数据的统计分析也可用于对发现网络问题。
测量数据较路测具体更全面、更完整、更易取得的优点。
与传统网管的不同，MR是由UE上报的，可以更直接的反应无线情况；MR测量中有毫秒级的KPI信息，后期可以结合信令分析出更；MR数据中包含UE位置信息，可以把数据的视角进一步放大，从小区扩展到具体的地理位置上。
2.MR系统概况测量报告数据采集原理MR测量报告数据主要来自UE，以及在无线资源管理过程中计算产生的测量报告。
原始测量数据或者经过统计计算报送到MR服务器以统计数据形式进行存储，生成MRS文件，或者直接报送到MR服务器以样本数据形式进行存储，最终生成MRO文件。
测量报告触发方式事件触发利用网络已开启的事件测量（A1、A2等），不需另外开启测量，测量数据周期性汇总生成MRE文件周期性触发需要手工开启测量任务，并配置上报周期，测量数据周期性汇总生成MRO和MRS文件目前我们的统计和分析数据源均采用周期性测量数据（即MRO和MRS文件）各类周期的定义：eNodeB或UE测量采样周期：reportInterval表示UE对某个测量数据进行测量的周期，目前要求统计设定为5120ms，即5.12S进行一次周期性测量。
reportAmount表示UE对某个测量数据进行的测量的数量，目前设置为infinity，表示无限制一直上报。
用sitemanager登到站上查看，这两个参数的位置在MRBTS-》LNBTS-》CTRLTS-》MTRACE-》Periodic UE measurements下。
通过测试软件查看RRC重配置信令消息，里面就包含reportInterval参数和reportAmount参数OMC-R（MR服务器）统计周期：表示OMC-R生成测量报告统计的周期，该周期目前统计设置为15分钟，即每个ENB 15分钟生成一个测量报告文件。
