Definitions
- the present invention relates to the field of communications, and in particular, to a method and apparatus for measuring >3 ⁇ 4.
- measurement is to obtain the signal quality of a serving cell and one or more neighboring cells through a User Equipment (UE), and report the obtained signal quality.
- the process of the ENodeB (Evolved Node B, also referred to as an evolved base station) to which the serving cell belongs.
- the measurement is controlled by the eNB, and the measurement configuration information is sent to the UE through the Radio Resource Control (RRC).
- RRC Radio Resource Control
- the UE performs the measurement operation according to the measurement configuration information, and reports the measurement result as required.
- the measurement results are used for handover and Inter-cell Interference Co-ordination (ICIC).
- the measurement configuration is uniquely identified by MeasID, including the measurement object and the report configuration:
- the measurement object determines a measurement target, and for the LTE system measurement, one measurement object is a group of cells belonging to the same carrier frequency;
- the reporting configuration includes a reporting method, such as an event-based trigger or a periodic trigger.
- event-triggered measurements there is one event type per measurement configuration.
- the event types are divided into Al, A2, A3, A4, A5, and each event type defines an entry condition and an exit condition.

- TTT TimeToTrigger
- the reporting process of the measurement report is triggered, and the neighboring cell is included in the measurement report; otherwise, if the signal measurement result of a neighboring cell satisfies the leaving condition of the specified event during the TTT period, The neighboring cell is cleared from the recorded CellsTriggeredList.
- the measurement configuration is configured to leave the trigger.

Description
测量上报的方法和装置
技术领域
本发明涉及通信领域， 尤其涉及一种测量上 >¾的方法和装置。
背景技术
在长期演进系统（LTE, Long Term Evolution ) 中， 测量（Measurement ) 是一种通过用户终端 （UE, User Equipment )获取服务小区和一个或多个邻 接小区的信号质量， 并将获得的信号质量上报给服务小区所属演进型节点 B ( eNB, Evolved Node B, 又称为演进型基站） 的过程。 测量由 eNB控制， 并将测量配置信息通过无线资源控制协议（ RRC, Radio Resource Control )下 发给 UE, UE根据测量配置信息执行测量操作， 并按要求上报测量结果。 其 中所述测量结果用于切换和小区间的干扰协调 （ICIC, Inter-cell Interference Co-ordination ) 。
测量配置由 MeasID唯一标识， 包括测量对象和上报配置：
所述测量对象决定测量的目标， 对于 LTE系统测量， 一个测量对象是属 于同一个载频的一组小区；
所述上报配置包括上报方法， 如基于事件触发或者周期性触发。
对于事件触发的测量， 每个测量配置有一个事件类型。 对于 LTE系统的 测量， 事件类型分为 Al、 A2、 A3、 A4、 A5 , 且每个事件类型都定义了一个 进入条件和离开条件。 例如， 为一个测量配置了一个事件类型， 若某个邻接 小区的信号质量测量结果在触发时间 （TTT, TimeToTrigger )期间内都满足 该事件类型的进入条件， 则将该邻接小区加入到测量报告实体内的触发小区 列表（CellsTriggeredList )中， 然后触发测量报告的上报过程， 且测量报告中 包含该邻接小区； 反之， 若某个邻接小区的信号测量结果在 TTT期间内都满 足指定事件的离开条件，则从已记录的 CellsTriggeredList中清除该邻接小区。 特别地，对于事件类型为 A3事件的测量，若某个邻接小区的信号测量结果在 TTT期间内都满足 A3事件的离开条件， 且该测量配置的 "离开触发上报测
量"属性（即 ReportOnLeave 置为真，则先将该邻接小区从 CellsTriggeredList 中清除， 然后触发测量报告的上报过程， 且测量报告中仅包含新
CellsTriggeredList中的邻接小区。 在现有技术中， eNB在收到测量报告后， 通过将测量报告中小区， 与前一次测量报告中的小区进行对比， 获知满足进 入条件和离开条件的邻接小区， 具体为：
确定存在某个小区， 出现在于最后一次测量才艮告中， 不出现在前一次测 量报告中， 则认为该小区满足了进入条件。
确定存在某个小区， 未出现在最后一次测量报告中， 但出现在前一次测 量报告中， 则认为该小区满足了离开条件。
在现有技术中， CellsTriggeredList中允许记录的最大小区数为 32, 而测 量报告中最大小区数受 "最大上报小区数" （即 maxCellReport ) 限制， maxCellReport最多为 8,即只有信号质量最好的 8个小区才会上报给网络侧。 如果某个小区曾经上报给网络侧， 但是当该小区满足离开条件的时候不是最 好的 8个小区之一， 则 eNB有可能不能检测到该小区的离开， 因为即使是不 是最好的 8个小区满足离开条件也会触发测量上报。因此可能存在如下场景， 如附图 1所示，假设 maxCellReport为 2; 在 T1时刻 ,有 Cell 1、 Cell 2和 Cell 3满足进入条件， 且信号质量的排序关系是 Cell 1 > Cell 2 > Cell 3 , 于是 Cell 1和 Cell 2被上报到 eNB。 在 T2时刻， Cell 4满足进入条件， 且信号质量的 4非序关系是 Cell 1 > Cell 4 > Cell 3 > Cell 2, 因此 Cell 1和 Cell 4被上才艮到 eNB。 在 T3时刻， Cell 3满足离开条件， CellsTriggeredList中包括 Cell 1 、 Cell 2和 Cell 4 , 且信号质量的排序为 Cell 1 > Cell 4 > Cell 2, 因此 Cell 1和 Cell 4被上报到 eNB, 此时因前后两次测量报告中小区列表完全一致， eNB 会判断出无小区满足离开条件， 与实际情况不符。
由于上述问题的存在， 使得 eNB根据 A3事件测量报告中满足进入条件 的邻接小区，无法准确确定满足离开条件的邻接小区，造成切换成功率和 ICIC 操作的准确性低。
