目前， MDT的测量内容主要包括以下几种：
1 )周期性的下行导频测量（ Periodical downlink pilot measurement )： 即 无线环境的测量， 例如公共导频信道接收信号码功率（CPICH RSCP ), 公 共导频信道每码片能量与干扰功率谱密度之比 （CPICH Ec/No ), 参考信号 接收功率（ R SRP )和参考信号接收质量（ RSRQ ) (只对连接模式）周期性 地记录。 这个测量日志对应于用户实例 "覆盖优化"。
运营商意识到下行链路（ DL )覆盖或可实现的吞吐量的主要测量是 DL 公共导频接收等级和信噪比（SIR )等级。 现存的无线资源管理（RRM )测 量的配置主要依赖于事件触发的测量报告和周期性报告。 也存在如下一些 限制：
a) 没有伴随的位置信息。 即使运营商用 DL覆盖问题能识别小区， 但 运营商仍需要通过执行路测 （Drive test ) 来确定小区中存在问题的区域， 因为准确位置信息可以被低的 DL公共导频接收等级 /SIR等级检测出来， 而不能从当前的 RRM机制中获得。
b) 现存的 RRM机制只允许在 UE已经连接到特定的小区，且有足够的
UL覆盖来传输测量报告时，进行测量报告。这将会限制从 UE收集的测量， UE不能经历可信链路帧（RLF, Reliable Linked Frame )和经历足够的上行 链路（UL )覆盖。
2 )服务小区信号小于阈值 ( Serving Cell becomes worse than threshold ): 即当服务小区的度量小于配置的阔值时，记录无线环境测量， 比如： CPICH RSCP , CPICH Ec/No , 或者 TDD 主公共信道接收信号码功率 （ TDD P-CCPCH RSCP )和干扰信号码功率（ISCP ), RSRP和 RSRQ (只对连接 模式）。 需要一个测量日志窗口， 目的是为了在事件发生的前后在某段时间 内可以搜集信息。 测量日志对应的是用户实例 "覆盖优化"。
如果运营商对一个特定的 DL覆盖问题感兴趣，釆取对应于感兴趣问题 的测量日志是有效的。为了能够找出问题区域，运营商能把它们的准则 (如： 在覆盖外）转化成阔值。 为了能够识别问题的特征（如： 发生在一个特定 的移动场景 ), 该项测量内容是有益的测量日志提供信息。
3 )传输功率余裕 ( headroom ) 小于阈值 ( Transmit power headroom becomes less than threshold ): 即当 UE的传输功率的 headroom小于配置的 阔值， 记录传输功率的 Headroom和无线环境测量比如： CPICH RSCP , CPICH Ec/No, 或者 TDD P-CCPCH RSCP和 ISCP, RSRP和 RSRQ (只对 连接模式）这个测量日志对应于用户实例 "覆盖优化"。
运营商从观察 UL传输功率的等级，可以检测出没有足够 UL的链路预 算，并且也可以推论出在网络中可以实现的 UL吞吐量等级。搜集这些信息 可以帮助运营商更好地调节 CIO , 来决定在网络中心小区的布局， 调节天 线倾角等等。
4 ) 随机接入失败（Random access failure ): 即随机接入失败发生时， 记录关于随机接入的详细信息和无线环境测量，比如： CPICH RSCP, CPICH Ec/No, 或者 TDD P-CCPCH RSCP和 ISCP, RSCP和 RSRQ (只有在连接 状态）。 这个测量日志对应的用户实例是 "覆盖优化"。
随机接入失败的原因是， 比如错误的传输功率设置或竟争等。 运营商 可以搜集关于随机接入失败的信息来分析随机接入失败的特征。 DL无线环 境的测量也是必要的， 比如 CPICH RSCP, CPICH Ec/No, RSRP和 RSRQ, 因为随机接入过程中的开环功率控制依赖于这些特征。 搜集这些信息可以 帮助运营商较好地调节随机接入参数， 调节天线倾角等。
5 )寻呼信道失败（ Paging Channel failure ): 即当 UE对 X2 的连续时 间内，在寻呼信道没有解码出 PCCH,记录无线环境的详细信息如位置信息， 时间和小区标识 （即使运营商在寻呼时刻能够解码出 PDCCH )。 这个测量 曰志对应于用户实例 "公共信道的参数化"。
在空闲（IDLE )模式下， 对于运营商来说， UE是否可以被可靠地寻呼 到是很重要的。 如果一个用户不能被可靠地寻呼到， 将会对用户体验（至 少在寻呼单元）有消极影响， 并且对于运营商的收入也有影响 （因为少了 呼叫的机会）。 在当前的网络中， 路测可以用于通过接收在小区覆盖区域中 的寻呼消息评估 UE的能力。 既然这些行为会造成高的成本， 如果 UE能记 录它自身在寻呼信道上不能解码信息发生的时间以及其他相关信息， 将是 非常有益。 6 )广播信道失败（ Broadcast Channel failure ): 即当 UE没有读到相关 DL公共信道来获得对于驻留在一个小区内需要的系统消息时，记录无线环 境的消息信息如位置信息， 时间， 小区标识和频率等。 这个测量对应了用 户实例 "覆盖和容量优化" 和 "公共信道的参数化"。
7 )无线链路失败报告 ( Radio Link failure report ): 即在 UE发生 RLF 时， UE报告无线测量， 如 CPICH RSCP, CPICH Ec/No, 或 TDD P-CCPCH 和 ISCP, RSRP和 RSRQ。 RLF Report的测量对应于 "覆盖优化" 的用户 实例。
RLF Report可以识别来自覆盖方面的几个问题。 因而在现实网络中， 通过 RLF Report测量信息进行覆盖漏洞的检测概率期望能高。 并且通常和 DL公共信道检测相关的一些问题也是由于覆盖问题引起的。 RLF Report提 供了解决基本 DL覆盖问题的方法，公共信道参数化的具体测量可以集中在 调节公共信道参数。
搜集上述 MDT的测量内容的测量信息，可以帮助运营商找出在指定区 域的覆盖问题， 减少人工路测。
同时， 移动用户的服务连续性是蜂窝移动通信系统的一个基本功能， 而移动台服务小区的切换是保证服务连续性的主要手段。 为了便于用户设 备进行切换， 系统需要给每个小区配置邻接关系， 以便网络侧将邻区信息 通知给用户设备， 用户设备对邻区进行测量后上报测量结果， 而网络侧根 据上报的测量结果指示用户设备切换至某一邻区。
某个小区周围有哪些邻区不仅与小区距离有关， 而且与小区所处的无 线环境密切相关。 由于无线环境错综复杂， 尤其是高层建筑密集的城区环 境， 在网络规划初期很难确切判断某个小区应该配置哪些邻区。 还有一些 如系统中新增加了一个小区或者小区属性改变， 没有及时更新小区的相邻 关系； 或者环境的变化、 网络规划人员的遗漏等， 都会造成邻区信息更新 不及时。 这样就会造成用户设备不能及时切换到其它的小区， 而使得本小 区的负载过高、 本小区信号质量变差、 干扰严重或者用户掉话等情况的发 生。
而前面提到的 MDT技术可以充分利用 UE的测量， 对周围无线环境情 况进行搜集上报， 目前，没有提供有效的测量方法使得 UE能够获得周围邻 区信息并进行上报。 发明内容
