Description

测量处理方法及系统、 基站和用户设备 技术领域 本发明涉及通信领域， 具体而言， 涉及一种测量处理方法及系统、 基站 和用户设备 ( User Equipment , 简称为 UE )。 背景技术 高级长期演进系统 （Long Term Evolution Advance, 简称为 LTE-A )提 出了载波聚合 ( Carrier Aggregation, 简称为 CA )技术， 其能够为具有相应 能力的 UE提供更大的宽带， 并提高 UE的峰值速率。 长期演进系统 （ Long Term Evolution, 简称为 LTE ) 中， 系统支持的最大下行传输带宽为 20MHz, 而在 LTE-A中， 通过载波聚合可以将两个或者更多的分量载波（component carriers, 简称为 CC ) 聚合起来以支持大于 20MHz, 最大不超过 100MHz的 传输带宽， 图 1是根据相关技术的载波聚合的示意图。 分量载波可以使用 LTE 已经定义的频段， 也可以使用为 LTE-A专门新 增的频段。 按各分量载波在频域上是否连续， 载波聚合可以分为连续的载波 聚合和非连续的载波聚合。 按各分量载波是否在同一频带内， 载波聚合可以 分为单频带（ single band )的载波聚合和跨频带（ over multiple frequency bands ) 的载波聚合， 所谓单频带的载波聚合是指参与载波聚合的所有分量载波都在 同一个频带内， 单频带的载波聚合可以是连续的载波聚合也可以是非连续的 载波聚合； 所谓跨频带的载波聚合是指参与载波聚合的分量载波可以源自不 同的频带。 具有载波聚合能力的 LTE-A UE可以同时在多个分量载波上收发 数据， 而 LTE UE只能在一个兼容 LTE的分量载波上收发数据。 参与载波聚 合的各分量载波的覆盖范围可能相同， 如图 2所示， 下行分量载波 CC1 和 CC2的覆盖范围相同； 参与载波聚合的各分量载波的覆盖范围也可能不同， 如图 3所示， 下行分量载波 CC2的覆盖范围大于下行分量载波 CC1的覆盖 范围。 在移动通信系统中， UE可以在各小区之间移动， 为了保证业务连续性， 确保业务质量， 在用户建立业务后， UE需要根据服务基站的配置进行测量， 并向服务基站报告满足服务基站配置要求的测量报告， 从而使服务基站可以 根据 UE 上报的测量 告以及其他无线资源管理 （ Radio Resource Management, 简称为 RRM ) 算法做出合理的切换判决， 即选择合理的目标 'J、区进行切换， 满足移动性要求。 在 LTE中， UE只能工作在一个载波（频率） 上， 只能在所工作载波的 一个小区上建立业务， 进行数据收发， 该小区称为 UE的服务小区。 因此在 LTE 系统中， 为了满足移动性需求， UE只需要以该服务小区为参考， 以单 独的频率为测量对象， 测量服务基站要求测量的频点上的部分或所有小区。 相应的 UE进行测量评估时， 只需要评估服务小区的信号强度， 比如 A1 , A2事件。或者只需要评估单个频率上的各相邻小区的信号强度相对于服务小 区的信号强度， 比如 A3事件， 用于评估某一个相邻小区的信号强度相对于 服务小区的信号强度超过一个偏移量； 又比如 A5事件， 用于评估服务小区 的信号强度低于某一门限且某一个相邻小区的信号强度高于某一个门限。 最 后 UE上报测量报告时也是以单个频率为粒度， 上报该频率上满足服务基站 配置的上报条件的小区的信号强度。 因为 UE能且仅能工作在一个服务小区 上， 因此服务基站进行切换判决时， 只需要根据 UE 以服务小区为参考的测 量报告和 /或其他 RRM算法进行切换判决， 选择一个频率上的一个小区作为 切换的目标小区， 为描述方便， 下文称 LTE中的服务小区为 UE满足移动性 测量的移动参考小区。
LTE-A系统中由于引入了载波聚合技术， 因此 UE可以工作在 N ( N<5 ) 个分量载波（频率）上， 即， UE可以同时在 N ( N<5 )个小区 （这些小区的 工作频点分别为上述 N个不同的分量载波）上进行数据收发，为了描述方便， 以下称 LTE-A中的这些小区为工作小区。若 UE以此 N个工作小区为参考进 行测量并上报各频率（包括上述 N个频率及其相邻频率）上各小区的信号强 度， 一方面会增加 UE测量的复杂性， 同时由于针对各个工作频点的大量测 量报告的产生， 将会消耗更多的无线资源； 另一方面也增加了基站进行测量 配置和切换判决的复杂性， 增加了系统开销。 发明内容 本发明的主要目的在于提供一种测量处理方法及系统、基站和用户设备， 以解决 LTE-A中 UE以多个小区作为参考小区进行测量及上报导致测量、 配 置和切换判决的复杂度提高的问题。 本发明的一个方面提供了一种测量处理方法， 包括： UE 的服务基站通 知 UE以预定小区作为 UE进行测量时的移动参考小区， 其中， 预定小区是 UE当前工作小区中的一个； UE以该预定小区作为移动参考小区进行测量。 本发明的另一个方面提供了一种基站， 其用于通知其月良务的 UE以预定 小区作为 UE进行测量时的移动参考小区， 以便 UE以该预定小区作为移动 参考小区进行测量， 其中， 预定小区是 UE当前工作小区中的一个。 本发明的又一个方面提供了一种用户设备 UE， 包括： 接收模块， 用于 接收来自 UE的服务基站的以预定小区作为 UE进行测量时的移动参考小区 的通知， 其中， 预定小区是 UE当前工作小区中的一个； 测量模块， 用于以 该预定小区作为移动参考小区进行测量。 本发明的再一个方面提供了一种测量处理系统， 包括 UE和基站， 其中， 该基站是 UE的服务基站， 基站， 用于通知 UE 以预定小区作为 UE进行测 量时的移动参考小区， 其中， 预定小区是 UE当前工作小区中的一个； UE， 用于以该预定小区作为移动参考小区进行测量。 通过本发明， 采用 UE的服务基站通知 UE在进行测量时的移动参考小 区， 后续 UE M居该移动参考小区进行测量（即以该移动参考小区作为参考 进行测量）的方法， 解决了 LTE-A中 UE以多个小区作为参考小区进行测量 及上 4艮导致测量、 配置和切换判决的复杂度提高的问题， 大大减少了 UE移 动性测量的复杂性和服务基站进行切换判决的复杂性。 附图说明 此处所说明的附图用来提供对本发明的进一步理解， 构成本申请的一部 分， 本发明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的 不当限定。 在附图中： 图 1是根据相关技术的载波聚合的示意图； 图 2是根据相关技术的一种分量载波覆盖示意图； 图

下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是， 在 不冲突的情况下， 本申请中的实施例及实施例中的特征可以相互组合。 本发明实施例提供了一种测量处理方法， 图 4是根据本发明实施例的测 量处理方法的流程图， 如图 4所示， 包括： 步骤 S402, UE的 J良务基站通知 UE 以预定小区作为 UE进行测量时的 移动参考小区， 其中， 该预定小区是 UE当前工作小区中的一个； 步骤 S404 , UE以该预定小区作为移动参考小区进行测量。 在现有技术中， UE 以其工作的多个工作小区为参考进行测量并上报各 频率上的小区的信号强度， 这会导致测量、 配置和切换判决复杂度的提高， 系统资源消耗较多。 而区别于现有 4支术， 本发明实施例提供的方法使得 UE 能够从其服务基站获得进行测量时的单个的移动参考小区， 并以该预定小区 作为移动参考小区进行测量， 大大降低了 UE移动性测量的复杂性和服务基 站进行切换判决的复杂性。 优选地， 步骤 S402之后， 还可以包括： 步驟 S403-1 , UE的服务基站配置 UE测量非移动参考小区的测量参数； 步驟 S403-2 , UE根据非移动参考小区的测量参数进行测量， 并将测量 结果上报服务基站。 需要说明的是， 步驟 S403-1和步骤 S404无固定的执行先后顺序， 并且 也可以同时执行， 步骤 S403-2和步骤 S404无固定的执行先后顺序， 并且也 可以同时执行， 步骤 S403-2在步骤 S403-1之后执行。 具体地， 步骤 S404可以包括： UE以移动参考小区作为参考， 按照 LTE 系统的测量方法进行测量。 具体地， UE 以该预定小区作为移动参考小区， 对服务基站配置的各个测量频点上的部分或全部小区进行测量， 并测量评估 预定小区的信号强度 （比如 Al , A2事件 )或者测量评估各个频点上的各相 邻小区的信号强度相对于预定小区的信号强度 （比如 A3， A5事件）。 步骤 S404之后， 该方法还可以包括： 步驟 S406 , UE向服务基站上报测 量结果。 在上述过程中， UE有且仅有一个移动参考小区， 大大降低了 UE移动性 测量的复杂性。 优选地， 步骤 S406之后， 还可以包括： 步驟 S408, 服务基站^^据预定 策略进行切换判决或进行移动参考小区变更判决， 其中， 预定策略包括测量 结果或预定小区和 /或 UE当前工作小区对应的载波覆盖范围， 还可以包括以 下至少之一： 无线资源管理 RRM算法、 载波管理算法、 预定小区和 /或 UE 的当前工作小区对应的载波的特性。 由于 UE有且仅有一个移动参考小区， 因此该步骤中的服务基站进行切换判决的复杂性较低。 优选地， 在步骤 S408 中的月良务基站？^据预定策略进行移动参考小区变 更判决之后， 该方法还可以包括以下步 4聚 S410、 步像 S412中的至少之一： 步骤 S410,在服务基站根据预定策略判决需要改变移动参考小区的情况 下， 服务基站通知 UE以另一预定小区作为 UE进行测量时的移动参考小区； 步骤 S412,服务基站通知 UE删除或去激活步驟 S402中的预定小区（原 来的预定小区）。 服务基站 M居预定策略判断不需要进行切换， 但需要改变 UE的移动参 考小区的情况下， 服务基站可以通知 UE更新移动参考小区， 和 /或， 服务基 站通知 UE删除或去激活原来的预定小区。 该过程中， 区别于 LTE系统， 即 使在 UE不进行切换时也可以半静态配置 /重配置移动参考小区， 服务基站可 以才 据实际情况重新配置 UE的移动参考小区， 能满足多载波系统下复杂的 无线覆盖和无线通信场景， 为服务基站进行合理的切换判决提供测量输入， 从而避免不必要切换。 优选地， 在步骤 S408 中的服务基站根据预定策略进行切换判决之后， 该方法还可以包括以下步骤 S414: 步骤 S414， 在服务基站根据预定策略判决需要进行切换的情况下， 服务 基站^ 1一个或多个切换目标小区通知 UE, 并以上述一个或多个切换目标小 区中的一个切换目标小区作为 UE进行测量时的移动参考小区。 服务基站根据预定策略判断需要切换的情况下， 命令 UE进行切换， 切 换命令中携带一个或多个切换目标小区的信息， 并指定 UE以目标小区中的 一个小区作为 UE进行测量时的移动参考小区。 UE接收到切换命令后会删除 所有正在工作的小区， 切换到目标小区上， 并以预定小区作为测量时的移动 参考小区。 以下通过具体实例对上述方法进行详细的描述。 实例 1 图 5是才 据本发明实例 1的测量处理方法的应用场景示意图， 如图 5所 示， 该区 i或内有三个下行分量载波， 分别为 CC1， CC2, CC3 , 其中 CC 1和 CC2的覆盖范围相同或者近似相同 （差别不大可以忽略）， CC3 的覆盖范围 较之 CC1和 CC2的覆盖范围大。 运营商在三个分量载波上可以进行独立的 网络规划， 并可以根据载波聚合的需求做适当的联合调整， 保证 LTE UE和 不具备载波聚合能力的 UE可以依据现有 LTE机制在各分量载波上进行正常 的通信， 同时满足 LTE-A UE进行载波聚合的需求。 本实例中， UE为具有载波聚合能力的 UE, UE的移动路线如图 5中带 箭头实曲线所示。 UE建立业务之初位于 1位置， 工作在 CC1 ( Celll , 即小 区 1 ), CC2 ( Cell2 , 与 Cell l覆盖范围相同， 图 5为二维覆盖示意图， 故未 作特殊标识）和 CC3 ( Cell3 )上， 服务基站根据各分量载波的覆盖范围或者 UE上报的各分量载波上的信号质量（测量结果之一）， 进一步地， 还可以才艮 据载波管理算法、 其他 RRM算法、 各分量载波的特性中的一个或多个因素 选择 UE当前的移动参考小区 （或称移动性测量参考小区， 移动性参考服务 小区）。 具体选择方式举例如下： 方式 1、 服务基站可以根据各分量载波（预定小区和 /或 UE当前工作小 区对应的载波） 的覆盖范围进行移动参考小区的选择， 本实例中， CC 1 和 CC2的覆盖范围相同且比 CC3小，服务基站选择位于小覆盖范围内的工作小 区（ Cell l或 Cell2 )作为移动参考小区，本实例服务基站任意选择其中的 Cell l。 方式 2 J良务基站可以才艮据各分量载波的覆盖范围以及 RRM算法进行移 动参考小区的选择， 本实例中 CC1和 CC2的覆盖范围相同且比 CC3小， 服 务基站选择位于小覆盖范围内的工作小区 （Celll或 Cell2 )作为移动参考小 区，同时服务基站根据 RRM算法中的动态资源分配法则判断 Cell2上的物理 资源使用负荷过大， 因此最终选择 Celll作为移动参考小区。 方式 3、 服务基站可以 4 据 UE上 4艮的各分量载波上的信号质量（测量 结果之一）选择移动参考小区， 比如本实例中， UE上报的测量报告中 Cell 1 的信号强度相比 Cell2和 Cell3最差， 故服务基站选择 Celll作为移动参考小 区。 方式 4、 服务基站可以根据各分量载波的覆盖范围以及载波管理算法进 行移动参考小区的选择，本实例中 CC1和 CC2的覆盖范围相同且比 CC3小， 服务基站选择位于小覆盖范围内的工作小区 （Celll或 Cell2 )作为移动参考 小区， 同时服务基站根据载波管理算法， 判断 cell2上业务负荷太大， 因此最 终选择 Cell 1作为移动参考小区。 方式 5、 服务基站可以根据各分量载波的覆盖范围以及各分量载波的特 性进行移动参考小区的选择，本实例中 CC 1和 CC2的覆盖范围相同且比 CC3 小， J艮务基站选择位于小覆盖范围内的工作小区 （Celll或 Cell2 )作为移动 参考小区， 同时服务基站 #>据 CC1 , CC2, CC3的特性， 判断 CC1和 CC3 是一种全功能分量载波， 而 CC2是一种扩展载波， 即 CC2能作为资源让连 接态的 LTE-A UE使用， 但是不能提供其他与移动性能相关的功能， 因此服 务基站最终选择 Cell 1作为移动参考小区。 良务基站通知 UE以 Celll作为当前该 UE的移动参考小区， 同时为 UE 配置以 Celll作为移动参考小区的相关测量配置。 服务基站根据 UE 以 Celll作为移动参考小区的测量结果或各小区对应 的载波覆盖范围 （预定小区（ Celll )和 /或 UE当前工作小区对应的载波覆盖 范围）， 进一步地， 还可以 #居载波管理算法、 其他 RRM算法（例如， 当前 UE的业务情况， Cell2、 Cell3的资源状况， Cell2, Cell3的干扰情况， 附近 相邻小区的资源状况等）、 预定小区和 /或 UE 当前工作小区对应的载波的特 性中的一个或多个因素进行切换判决， 选择目标切换小区或者改变移动参考 小区。 UE以 Celll作为移动参考小区， 并按照服务基站配置的以 Celll作为 移动参考小区的相关测量配置进行测量， 例如， 服务基站配置以 Celll 作为 参考对象， 测量分量载波 CC3上的相邻小区相对于 Cell的信号强度超过预 定偏移量的 A3事件， 并上报满足服务基站配置的上报条件的测量报告给服 务基站。 对于非移动参考小区 Cell2和 Cell3 , 为了满足干扰控制或分量载波管理 等需求，服务基站可以根据需要为 UE配置相应的测量， UE按照服务基站的 测量配置执行测量， 进行测量评估并上报满足服务基站配置的上报奈件的测 量报告给服务基站。
UE逐渐移动进入位置 3的 Celll的切换区域， UE在 Celll的切换区域 内按照服务基站的测量配置执行测量， 上报满足服务基站配置的上报条件的 各种测量报告。 在位置 3的切换区域内， 服务基站根据 UE上报的各种测量 报告或各小区对应的载波（预定小区（Celll )和 /或 UE的当前工作小区对应 的载波）覆盖范围， 进一步地， 还可以根据载波管理算法、 其他 RRM算法、 各小区对应的载波的特性中的一个或多个因素进行判断， 如果判断 UE可以 继续在 Cell3和 /或 Cell2上进行艮好的业务传输， 满足当前的业务需求， 良 务基站不命令 UE进行切换。 当 UE移动到 2位置， 若服务基站根据 UE以 Cell 1作为移动参考小区的测量结果， 判断 UE不能继续在 Cell 1上进行业务 传输， 则服务基站改变 UE的移动参考小区为 Cell3 , 并通知 UE以 Cell3作 为当前该 UE的移动参考小区， 同时为 UE配置 /重配置以 Cell3作为移动参 考小区的相关测量配置， 与此同时月艮务基站通知 UE删除 Celll或者去激活 Celll。 此后， 服务基站根据 UE 以 Cell3作为移动参考小区的测量结果或各 ,J、 区对应的载波的覆盖范围 （预定小区（Cell3 )和 /或 UE当前工作小区对应的 载波覆盖范围）， 进一步地， 还可以根据载波管理算法、 其他 RRM算法、 预 定小区和 /或 UE当前工作小区对应的载波的特性中的一个或多个因素进行切 换判决， 选择目标切换小区或者改变移动参考小区。 UE接收到服务基站的 通知后， 以 Cell3作为移动参考小区， 并按照服务基站配置的以 Cell3作为移 动参考小区的相关测量配置进行测量， 并停止在 Celll上进行业务传输。 在位置 3 的 Celll的切换区域， 如果服务基站根据 UE上报的各种测量 报告或各小区对应的载波的覆盖范围 （预定小区（Celll )和 /或 UE当前工作 小区对应的载波覆盖范围），进一步地，还可以 ^艮据载波管理算法、其他 RRM 算法、 预定小区和 /或 UE当前工作小区对应的载波的特性中的一个或多个因 素进行切换判决， 若服务基站判断 Cell2， Cell3上因为千扰太大， 负荷过重， 资源紧张等原因导致 UE不可能继续在 Cell2， Cell3上进行满足当前业务需 求的数据传输， 服务基站可以选择合适的目标小区（一个或多个）进行切换， 并通知 UE以一个或多个目标小区中的一个目标小区作为 UE切换之后的移 动参考小区。 该实例中， 在 2 位置之前， 服务基站为 UE 配置了一个移动参考小区
Celll , 在 2位置之后， 服务基站重新配置 UE的移动参考小区为 Cell3。 也就 是说， 服务基站可以半静态配置 /重配置 UE的移动参考小区， 因为 UE有且 仅有一个移动参考小区， 大大降低了 UE移动性测量的复杂性和服务基站进 行切换判决的复杂性。 实例 2 图 6是根据本发明实例 2的测量处理方法的应用场景示意图， 如图 6所 示， 该区域内有三个下行分量载波， 分别为 CC1， CC2, CC3 , 其中 CC1和 CC2的覆盖范围相同或者近似相同 （差别不大可以忽略）， CC3 的覆盖范围 较之 CC1和 CC2的覆盖范围大。 运营商在三个分量载波上可以进行独立的 网络规划， 并可以根据载波聚合的需求做适当的联合调整。 本实例中， UE为具有载波聚合能力的 UE, UE的移动路线如图 6中带 箭头实曲线所示。 UE建立业务之初位于 1位置， 工作在 CC1 ( Celll ), CC2 ( Cell4 , 与 Celll覆盖范围相同， 图 6为二维覆盖示意图， 故未作特殊标识） 和 CC3 ( Cell3 )上， 服务基站根据各分量载波的覆盖范围或者 UE上报的各 分量载波上的信号质量， 进一步地， 还可以坤 据载波管理算法、 其他 RRM 算法、 各分量载波的特性中的一个或多个因素选择 UE当前的移动参考小区 (或称移动性测量参考小区，移动性参考服务小区），本实例中服务基站选择 Celll作为 UE当前的移动参考小区， 并通知 UE以 Celll作为当前该 UE的 移动参考小区， 同时为 UE配置以 Celll作为移动参考小区的相关测量配置。 服务基站根据 UE以 Celll作为移动参考小区的测量结果或各小区对应 的载波的覆盖范围 （预定小区（Celll )和 /或 UE当前工作小区对应的载波覆 盖范围）， 进一步地， 还可以根据载波管理算法、 其他 RRM算法、 预定小区 和 /或 UE 当前工作小区对应的载波的特性中的一个或多个因素进行切换判 决， 选择目标切换小区或者改变移动参考小区。 UE以 Celll作为移动参考小 区， 并按照服务基站配置的以 Celll 作为移动参考小区的相关测量配置进行 测量， 并上报满足服务基站配置的上报条件的测量报告给服务基站。 同样对于非移动参考小区 Cell4和 Cell3， 为了满足千 ^尤控制或分量载波 管理等需求，服务基站可以根据需要为 UE配置相应的测量， UE按照服务基 站的测量配置执行测量， 进行测量评估并上报满足服务基站配置的上报条件 的测量报告给服务基站。 UE逐渐移动进入位置 4的 Celll的切换区域， UE在 Celll的切换区域 内按照服务基站的测量配置执行测量， 上报满足服务基站配置的上报条件的 各种测量报告。 在位置 4的切换区域内， 服务基站根据 UE上报的各种测量 报告或各小区对应的载波覆盖范围 （预定小区（Celll )和 /或 UE当前工作小 区对应的载波覆盖范围）， 进一步地， 还可以^^据载波管理算法、 其他 RRM 算法、 预定小区和 /或 UE当前工作小区对应的载波的特性中的一个或多个因 素， 判断 UE在 Cell3上的信号强度足够好， 在 Cell4上受到很大千扰， 但 UE可以继续在 Cell, Cell3 , Cell4上进行很好的业务传输， 为了避免不必要 的切换导致系统资源的浪费，服务基站不命令 UE进行切换。 当 UE移动到 2 位置， 服务基站根据 UE上报的测量报告， 判断 UE不能继续在 Celll上进行 业务传输， 而 Cell2的信号强度满足条件可以与 Cell3进行聚合，服务基站通 知 UE删除 Celll和 Cell4， 新增 Cell2， 即 UE以 Cell3和 Cell2进行载波聚 合， 并通知 UE以 Cell2作为当前该 UE的移动参考小区， 同时为 UE配置 / 重配置以 Cell2作为移动参考小区的相关测量配置。 此后， 服务基站根据 UE 以 Cell2作为移动参考小区的测量结果或各 ,J、 区对应的载波的覆盖范围 （预定小区（ Cell2 )和 /或 UE当前工作小区对应的 载波覆盖范围）， 进一步地， 还可以根据载波管理算法、 其他 RRM算法、 预 定小区和 /或 UE当前工作小区对应的载波的特性中的一个或多个因素进行切 换判决选择目标切换小区。 UE接收到服务基站的通知后，删除 Cell 1和 Cell4 , 以 Cell2作为移动参考小区，并按照服务基站配置的以 Cell2作为移动参考小 区的相关测量配置进行测量， UE在 Cell2和 CelB上进行业务传输。 服务基站根据 UE上报的测量报告，判断 UE移动进入位置 5的 Cell3的 切换区域， 在 3位置， 服务基站改变 UE的移动参考小区为 CelB , 并通知 UE以 Cell3作为当前该 UE的移动参考小区，同时为 UE配置 /重配置以 Cell3 作为移动参考小区的相关测量配置。 此后， 服务基站根据 UE 以 Cell3作为移动参考小区的测量结果或各小 区对应的载波的覆盖范围 （预定小区（Cell3 )和 /或 UE的当前工作小区对应 的载波覆盖范围）， 进一步地， 还可以根据载波管理算法、 其他 RRM算法、 预定小区和 /或 UE当前工作小区对应的载波的特性中的一个或多个因素进行 切换判决选择目标切换小区。 UE接收到服务基站的通知后， 以 Cell3作为移 动参考小区， 并按照 J良务基站配置的以 Cell3作为移动参考小区的相关测量 配置进行测量， UE继续在 Cell2和 Cell3上进行业务传输。 实例 3 图 7是才 据本发明实例 3的测量处理方法的应用场景示意图， 如图 7所 示， 该区域内有两个下行分量载波， 分别为 CC1和 CC2， 两者的覆盖范围相 同或者近似相同（差别不大可以忽略）。运营商在两个分量载波上可以进行独 立的网络规划， 并可以根据载波聚合的需求做适当的联合调整。 本实例中， UE为具有载波聚合能力的 UE, UE的移动路线如图 7中带 箭头实曲线所示。 UE工作在 CC1 ( Celll ) 和 CC2 ( Cell2 ) 上， UE建立业 务之初位于 1位置， 服务基站判断 CC1和 CC2的覆盖范围相同， 服务基站 根据 RRM算法 （例如， CC1， CC2上的负荷， 资源使用情况等）选择 Celll 作为 UE当前的移动参考小区， 并通知 UE以 Celll作为当前该 UE的移动参 考小区， 同时为 UE配置以 Celll作为移动参考小区的相关测量配置。 同样对于非移动参考小区 Cell2,为了满足千扰控制或者分量载波管理等 需求，服务基站根据需要为 UE配置相应的测量， UE按照服务基站的测量配 置执行测量， 进行测量评估并上报满足服务基站配置的上报条件的测量报告 给服务基站。 服务基站根据 UE的测量报告，判断 UE移动进入位置 3的 Celll的切换 区域， 服务基站根据 RRM算法， 判断在 3区域内 Celll上的负荷过重， 或者 Celll上的资源紧张， 或者 UE在 Celll上受到 艮大的上下行干 4尤等原因， 需 要停止该 UE在 Celll上的业务通信， 同时服务基站综合考虑 Cell2的信号强 度及负荷， 资源等状况以及 UE当前的业务流量， 判断 Cell2能独立为 UE提 供很好的业务传输， 为了避免不必要的切换， 服务基站在 2位置改变 UE的 移动参考小区为 Cell2 , 通知 UE以 Cell2作为当前该 UE的移动参考小区， 同时为 UE配置 /重配置以 Cell2作为移动参考小区的相关测量配置， 并通知 UE删除或去激活 Celll。 此后， 服务基站根据 UE以 Cell2作为移动参考小区的测量结果或各 ,J、 区对应的载波的覆盖范围， 进一步地， 还可以才艮据载波管理算法、 其他 RRM 算法、 预定小区和 /或 UE当前工作小区对应的载波的特性中的一个或多个因 素进行切换判决，选择目标切换小区。 UE接收到服务基站的通知后，以 Cell2 作为移动参考小区， 按照服务基站配置的以 Cell2作为移动参考小区的相关 测量配置进行测量， 并停止在 Celll上进行业务传输。 本发明实施例还提供了一种基站， 该基站用于通知其服务的 UE以预定 小区作为 UE进行测量时的移动参考小区， 以便 UE以预定小区作为移动参 考小区进行测量， 其中， 预定小区是 UE当前工作小区中的一个。 本发明实施例还提供了一种用户设备， 图 8是根据本发明实施例的用户 设备的结构框图， 如图 8所示， 该用户设备包括： 接收模块 82， 用于接收来 自 UE的服务基站的以预定小区作为 UE进行测量时的移动参考小区的通知， 其中， 预定小区是 UE的当前工作小区中的一个； 测量模块 84， 连接于接收 模块 82 , 用于以预定小区作为移动参考小区进行测量。 本发明实施例还提供了一种测量处理系统， 图 9是根据本发明实施例的 测量处理系统的结构框图， 如图 9所示， 该系统包括： UE 92和基站 94, 基 站 94是 UE 92的月良务基站，基站 94，用于通知 UE 92以预定小区作为 UE 92 进行测量时的移动参考小区， 其中， 预定小区是 UE 92当前工作小区中的一 个； UE 92 , 用于以预定小区作为移动参考小区进行测量。 优选地， UE 92还用于向基站 94上报测量结果。 综上所述， 本发明实施例提供的测量处理方案大大减少了 UE移动性测 量的复杂性和服务基站进行切换判决的复杂性， 能够在不影响 LTE UE和不 具备载波聚合能力的 UE的测量的同时， 支持 LTE-A系统的测量， 服务基站 可以坤 M居实际情况重新配置 UE的移动参考小区， 能满足多载波系统下复杂 的无线覆盖和无线通信场景，为服务基站进行合理的切换判决提供测量输入， 从而避免了不必要切换。 显然， 本领域的技术人员应该明白， 上述的本发明的各模块或各步骤可 以用通用的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布 在多个计算装置所组成的网络上， 可选地， 它们可以用计算装置可执行的程 序代码来实现， 从而， 可以将它们存储在存储装置中由计算装置来执行， 并 且在某些情况下， 可以以不同于此处的顺序执行所示出或描述的步骤， 或者 将它们分别制作成各个集成电路模块， 或者将它们中的多个模块或步骤制作 成单个集成电路模块来实现。 这样， 本发明不限制于任何特定的硬件和软件 结合。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本 领域的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和 原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护 范围之内。
