而且 UE如果频繁上报测量报 告也会占用过多的无线资源。 因此, 为了一方面满足连接态下 UE的移动性 要求, 另一方面又不消耗太多电量, 不影响 UE在服务小区的通信, LTE系 统中, 服务基站根据 UE在服务小区的信号质量判断是否为 UE配置异频 /异 系统测量, 具体地, 可以按照以下的策略进行配置: 才艮据基站为 UE配置的 针对服务小区的测量事件一事件 A1 (服务小区的信号质量大于门限)和事件 A2 (服务小区的信号质量小于门限) 的测量结果确定 UE是否进行或停止异 频 /异系统测量任务, 基站接收到 UE上报的 A2事件时, 可以为 UE配置异 频 /异系统测量任务, 而接收到 UE上报的 A1事件时, 可以删除此前配置给 UE的异频 /异系统测量任务。 在 LTE系统中, 为了保证 UE的通信质量, UE切换到相邻小区时需要 保证相邻小区的信号足够为 UE提供有保证的通信质量,因此基站需要为 UE 配置针对相邻小区的测量事件, 如 A3 事件 (相邻小区的信号质量比服务小 区好一个偏移量)和 A5事件(服务小区的信号质量小于门限 1 , 相邻小区的 信号质量高于门限 2 ), 这些事件都需要同时考虑服务小区的信号质量和相邻 小区的信号质量, 是一种比较型事件。 基站接收到 UE上报的 A3或 A5事件 的测量艮告时, 可以 居测量艮告及其他 RRM算法进行切换的判决, 确定 是否将 UE切换到相邻的小区。 在载波聚合中, 基站可以为 UE配置多个载波的信息 (称为配置载波或 者工作载波), 并且激活其中的部分或者全部载波, 让 UE同时在这些激活的 载波上进行数据传输, 这些载波称为激活载波, 而其他已经配置但尚未激活 的载波可以称为非激活的载波。 在为载波聚合的 UE提供更大带宽和更高数据速率的同时, UE的耗电量 是设计载波聚合相关技术需要重点考虑的问题之一, 因此为了既保证 UE的 通信质量, 又不消耗太多电量, 载波聚合中基站也需要综合考虑各个激活载 波的信号质量, 判断是否为 UE配置异频 /异系统测量。 把 UE切换到相邻的 小区, 在切换过程中会短时间中断 UE在服务小区的数据传输, 甚至造成一 定的数据丢失, 同时切换过程本身也会带来较大的系统开销, 因此除了一些 运营商的特殊策略 (比如负载均衡) 夕卜, 除非 UE在服务小区无法保证数据 传输质量的要求, 或者基站确定有比当前服务小区更好的相邻小区, 否则基 站一般不会轻易把 UE切换到相邻小区。 在载波聚合中, 为了尽量减少不必 要的切换, 基站也需要综合考虑各个激活载波的信号质量, 判断是否把 UE 切换到相邻小区上。 发明人发现相关技术中, UE 检测到基站配置的任一测量任务满足触发 条件, 例如, 服务小区满足相关事件(A1事件和 A2事件) 的进入触发条件 或离开触发条件, 或相邻小区满足比较型事件( A3事件和 A5事件) 的进入 触发条件时, 就生成测量报告并上报给基站, 即, 对于所有的测量任务均釆 取触发即报的策略, 这种上报方法应用到载波聚合中缺乏灵活度。 发明内容 本发明的主要目的在于提供一种多载波系统下测量结果的上 4艮方法、 系 统及用户设备, 以至少解决上述问题。 根据本发明的一个方面,提供了一种多载波系统下测量结果的上报方法, 包括: 将测量任务分成测量任务组;

步骤 S204, UE判断测量任务组内测量任务的测量结果满足对应该测量 任务组的上报条件; 步骤 S206 , UE 居测量结果生成测量 ~¾告, 并上 ~¾所生成的测量 4艮告。 相关技术中, UE 对于所有的测量任务均釆取触发即报的策略, 这种做 法缺乏灵活度, 并且可能增加基站处理的复杂度, 以及增加系统的开销。 本 发明实施例提供的方法中, 通过将全部的测量任务分成测量任务组, 并在测 量任务组内的测量结果满足该测量任务组对应的上报条件的情况下, 才进行 测量结果的上 4艮, 通过该方法, 可以针对不同测量任务组配置不同的上 4艮条 件, 使得测量上报更加灵活, 并且, 在釆用合适的上报条件的情况下, 还可 以减少基站处理的复杂度, 并且能够减少系统的开销。 优选地, 将测量任务分成测量任务组的过程可以包括以下方式之一: 网 络侧将测量任务分成测量任务组, 并在测量控制消息中显式指定给 UE; UE 接收到测量控制消息后, 根据预先设定的规则将测量任务分成测量任务组。 其中, 由网络侧进行分组并通知 UE的方式使得分组的方式更加灵活, UE按 照预先设定的规则进行分组能够节省网络侧和 UE之间的信令交互。 优选地, 将测量任务分成测量任务组的过程包括: 将测量对象为工作载 波, 测量事件相同的测量任务分在同一个测量任务组中。 通过该分组方式, 能够简化 UE端的处理, 并且能够按照不同的组选择相应的上报条件, 提高 上报的灵活性。 优选地, 对应上述测量任务组的上 4艮条件可以包括: 测量任务组内有 M 个测量任务满足进入触发条件, 其中, M<=测量任务组中包含的测量任务数 量。 通过该上报条件, 减小了上报的次数, 从而减小了系统的开销。 具体地, 该上报条件可以包括以下至少之一: 条件 1 , 测量任务组内测量任务对应的测量对象中出现第一个满足 A1 事件的进入触发条件的工作载波; 条件 2, 测量任务组内测量任务对应的测量对象中出现最后一个满足 A2 事件的进入触发条件的工作载波。 相关技术载波聚合系统下的测量上报方法中, 一方面, 各个载波上的
A1/A2事件并不一定是同时上报的, 基站无法像 LTE系统那样通过 UE上报 的一个测量报告 ( A1/A2事件) 判断是否为 UE配置异频 /异系统测量任务, 增加了基站处理的复杂度; 另一方面, 各个载波上分别上报 A1/A2事件, 相 比 LTE系统增加了测量报告的数量, 占用了有限的空口资源, 增加了系统开 销。 釆用本发明实施例提供的方法, 通过将组内的测量上报条件设置为条件 1 ,仅在服务小区中出现第一个能够满足 A1事件进入触发条件的工作载波的 情况下, 上报测量报告, 当服务小区中已存在满足 A1 事件进入触发条件的 工作载波时, 即使 UE判断又出现了满足 A1事件进入触发条件的工作载波, 也不进行上报, 减小了上报的次数, 从而减小了系统的开销。 在服务小区一 出现满足 A1 事件的载波时, 将测量结果上报给网络侧, 网络侧通过该结果 即可确定应当删除 jt匕前配置给 UE的异频 /异系统测量任务, 减小了网络侧处 理的复杂度, 并且能够尽可能快地结束异频 /异系统测量, 节省了电量。 另外, 通过将组内的测量上报条件设置为条件 2, 仅在服务小区中出现 最后一个能够满足 A2事件进入触发条件的工作载波的情况下, 上报测量报 告, 即, 只有该组内的所有的测量任务均已满足 A2事件的情况下, UE才进 行上 4艮, 减少了上 4艮的次数, 从而减小了系统的开销。 在月艮务小区中所有的 载波均满足 A2事件的情况下, 将测量结果上报给网络侧, 网络侧通过该结 果即可确定应当为 UE配置异频 /异系统测量任务, 减小了网络侧处理的复杂 度, 并且, 能够尽可能少地配置异频 /异系统测量任务, 节省了电量。 在具体实施中, 上 4艮条件为条件 1 时, UE判断测量任务组内测量任务 的测量结果满足对应测量任务组的上报条件的过程可以釆用以下两种处理方 式之一来实现: 方式 1 , UE判断测量任务组内存在所对应的测量对象满足所对应的 A1 事件的进入触发条件的测量任务, 且当前计数器的值为 1 , 则判断测量结果 满足上报条件, 其中, 计数器在测量任务组内存在所对应的测量对象满足所 对应的 A1事件的进入触发条件的测量任务的情况下增 1 ,存在所对应的测量 对象满足所对应的 A 1事件的离开触发条件的测量任务的情况下减 1 ,计数器 初值为 0; 方式 2, UE判断测量任务组内存在所对应的测量对象满足所对应的 A1 事件的进入触发条件的测量任务, 且测量任务组内其他测量任务的小区列表 不存在, 则判断测量结果满足上报条件。 通过以上两种方式, UE 侧均能够简便地实现上报条件的判断, 且处理 开销较小, 同时能够减少上报次数, 减小网络侧处理复杂度, 并且能够尽可 能快地结束异频 /异系统测量, 节省了电量。 在具体实施中, 上 4艮条件为条件 2 时, UE判断测量任务组内测量任务 的测量结果满足对应测量任务组的上报条件的过程可以釆用以下两种处理方 式之一来实现: 方式 3 , UE判断测量任务组内存在所对应的测量对象满足所对应的 A2 事件的进入触发条件的测量任务, 且当前计数器的值为 N, 则判断测量结果 满足上报条件, 其中, 计数器在测量任务组内存在所对应的测量对象满足所 对应的 A2事件的进入触发条件的测量任务的情况下增 1 ,存在所对应的测量 对象满足所对应的 A2事件的离开触发条件的测量任务的情况下减 1 ,计数器 初值为 0, N为测量任务组中对应的测量事件为 A2事件的测量任务的总数; 方式 4, UE判断测量任务组内存在所对应的测量对象满足 A2事件的进 入触发条件的测量任务,且测量任务组内所有其它测量任务的小区列表非空, 则判断测量结果满足上报条件。 通过以上两种方式, UE 侧均能够简便地实现上报条件的判断, 且处理 开销较小, 同时能够减少上报次数, 减小网络侧处理的复杂度, 并且能够尽 可能少地配置异频 /异系统测量任务, 节省了电量。 优选地,在 A1事件的进入条件门限和 A2事件的离开条件门限设置相同, A1事件的离开条件门限和 A2事件的进入条件门限设置相同的情况下, 将测 量任务分成测量任务组包括: UE将测量对象为工作载波, 且触发事件为 A1 事件或 A2事件的测量任务分在同一个测量任务组中。 在 A1事件和 A2事件 的上述参数配置相同的情况下, 可以釆取以上的分组方式, 能够减少划分的 组的数量, 从而进一步减少上报次数。 在具体实施中, 该上 4艮条件为条件 1 时, UE判断测量任务组内测量任 务的测量结果满足对应测量任务组的上报条件的过程可以釆用以下方式来实 现: 方式 5 , UE判断测量任务组内存在所对应的测量对象满足对应的 A 1事 件的进入触发条件的测量任务, 且当前双事件计数器的值为 1 , 则判断测量 结果满足上报条件, 其中, 双事件计数器在测量任务组内存在所对应的测量 对象满足所对应的 A 1事件的进入触发条件的测量任务的情况下增 1 ,存在所 对应的测量对象满足对应的 A2事件的进入触发条件的测量任务的情况下减 1 , 双事件计数器初值为 0。 通过以上方式, UE侧能够简便地实现上报条件的判断, 且处理开销较 小, 同时能够减少上报次数, 减小网络侧处理复杂度, 并且能够尽可能快地 结束异频 /异系统测量, 节省了电量。 在具体实施中, 该上 4艮条件为条件 2 时, UE判断测量任务组内测量任 务的测量结果满足对应测量任务组的上报条件的过程可以通过以下方式来实 现: 方式 6, UE判断测量任务组内存在所对应的测量对象满足所对应的 A2 事件的进入触发条件的测量任务, 且当前双事件计数器的值为 0, 则判断测 量结果满足上报条件, 其中, 双事件计数器在测量任务组内存在所对应的测 量对象满足对应 A1事件的进入触发条件的测量任务的情况下增 1 ,存在所对 应的测量对象满足对应 A2事件的进入触发条件的测量任务的情况下减 1 ,双 事件计数器初值为 0。 通过以上方式, UE 侧能够简便地实现上报条件的判断, 且处理开销较 小, 同时能够减少上报次数, 减小网络侧处理的复杂度, 并且能够尽可能少 地配置异频 /异系统测量任务, 节省了电量。 优选地, 将测量任务分成测量任务组包括: 将测量对象为相同的载波, 测量事件为比较型事件且事件类型相同, 比较的参考小区为不同的服务小区 的测量任务划分在同一个测量任务组中。 通过该分组方式, 能够简化 UE端 的处理, 并且能够按照不同的组选择相应的上报条件, 提高上报的灵活性。 优选地, 该上 4艮条件可以包括: 测量任务组内测量对象上的一个小区分 别对应的 M个测量任务满足事件进入触发条件, 其中, M<=测量任务组中包 含的测量任务数量。 具体地, 该上报条件可以包括以下至少之一: 条件 3 , 测量任务组内一个测量任务对应的测量对象上的一个相邻小区 相对于该测量任务的参考小区满足比较型事件的进入触发条件; 条件 4, 测量任务组内所有测量任务对应的测量对象上的同一个相邻小 区相对于所有测量任务中的各测量任务的参考 ' j、区满足比较型事件的进入触 发条件; 条件 5 , 测量任务组内一个测量任务对应的测量对象上的一个相邻小区 相对于该测量任务的参考小区满足比较型事件的离开触发条件; 条件 6, 测量任务组内所有测量任务对应的测量对象上的同一个相邻小 区相对于所有测量任务中的各测量任务的参考小区满足比较型事件的离开触 发条件; 其中, 比较型事件为 A3事件或 A5事件。 相关技术中, 载波聚合中 UE可以工作在多个载波上, 即 UE工作在多 个服务小区上,一个相邻小区相对于不同的服务小区将触发不同的测量报告, 一方面, 这些测量 4艮告的上 4艮并不一定是同时上 4艮的, 基站无法像 LTE系统 那样通过一个测量 4艮告^ 出合理的切换判决, 另一方面触发太多测量 4艮告也 会占用有限的空口资源, 增加系统开销。 釆用本实施例提供的方法, 通过将组内的测量上报条件设置为条件 3 , 在测量任务组内一个测量任务对应的测量对象上的一个相邻小区相对于该测 量任务的参考小区满足比较型事件的进入触发条件的情况下,上报测量报告, 否则不上报; 和 /或条件 5 , 在测量任务组内一个测量任务对应的测量对象上 的一个相邻小区相对于该测量任务的参考小区中满足比较型事件的离开触发 条件的情况下, 上 4艮测量 4艮告, 否则不上 4艮, 减少了上 4艮的次数, 从而减小 了系统的开销。 另外, 由于在载波聚合中, 可以进行聚合的载波 (即相同基 站下, 除了已经配置给 UE的工作载波之外, 还可以配置给 UE的所有能进 行聚合的载波) 与工作载波之间的比较型事件, 和工作载波之间的比较型事 件用于为网络侧做载波管理 (包括为 UE添加工作载波, 删除工作载波, 用 未配置的载波替换已经配置的工作载波, 主载波的改变等) 提供依据, 因此 在测量对象相对于一个服务小区满足比较型事件的进入(条件 3 )或离开(条 件 5 ) 触发条件的情况下上报测量报告, 基站可以根据该测量报告及时的做 出载波管理的决策, 满足载波聚合中 UE高数据速率传输的需求。 通过将组内的测量上报条件设置为条件 4, 在测量任务组内所有测量任 务对应的测量对象上的同一个相邻小区相对于所有测量任务中的各测量任务 的参考小区满足比较型事件的进入触发条件的情况下, 上报测量报告, 否则 不上 4艮; 和 /或条件 6, 在测量任务组内所有测量任务对应的测量对象上的同 一个相邻小区相对于所有测量任务中的各测量任务的参考小区满足比较型事 件的离开触发条件的情况下, 上报测量报告, 否则不上报, 减少了上报的次 数, 从而减小了系统的开销。 另外, 由于比较型事件用于为网络侧做切换判 决提供依据, 因此, 釆用条件 4能够尽量减少切换次数, 从而节省了系统的 切换处理开销, 另外, 釆用条件 6能够更好的辅助基站进行切换判决。 在具体实施中, 该上 4艮条件为条件 3 时, UE判断测量任务组内测量任 务的测量结果满足对应测量任务组的上 4艮条件的过程可以通过以下的方式来 实现: 方式 7, UE判断测量任务组内存在一个测量任务所对应的测量对象上的 一个相邻小区相对于该测量任务的参考小区满足比较型事件的进入触发条 件, 且测量任务组内其他测量任务的小区列表不存在或者小区列表中不存在 该相邻小区, 则判断测量结果满足上报条件。 通过该方式, 能够减少上报次 数。 在具体实施中, 该上 4艮条件为条件 4 时, UE判断测量任务组内测量任 务的测量结果满足对应测量任务组的上 4艮条件的过程可以通过以下的方式来 实现: 方式 8, UE判断测量任务组内存在一个测量任务所对应的测量对象上的 一个相邻小区相对于该测量任务的参考小区满足比较型事件的进入触发条 件, 且测量任务组内所有测量任务的小区列表都存在该相邻小区, 则判断测 量结果满足上报条件。 通过该方式, 能够减少上报次数, 并节省了系统的切 换处理开销。 在具体实施中, 该上 4艮条件为条件 5 时, UE判断测量任务组内测量任 务的测量结果满足对应测量任务组的上报条件的过程可以通过以下的方式来 实现: 方式 9, UE判断测量任务组内存在一个测量任务所对应的测量对象上的 一个相邻小区相对于该测量任务的参考小区满足比较型事件的离开触发条 件, 且测量任务组内其他测量任务的小区列表不存在或者小区列表中不存在 该相邻小区, 则判断测量结果满足上报条件。 通过该方式, 能够减少上报次 数, 并且基站可以根据该测量报告及时的做出载波管理的决策, 满足载波聚 合中 UE高数据速率传输的需求。 在具体实施中, 该上 4艮条件为条件 6 时, UE判断测量任务组内测量任 务的测量结果满足对应测量任务组的上 4艮条件的过程可以通过以下的方式来 实现: 方式 10, UE判断测量任务组内存在一个测量任务所对应的测量对象上 的一个相邻小区相对于该测量任务的参考小区满足比较型事件的离开触发条 件, 且测量任务组内所有测量任务的小区列表都存在该相邻小区, 则判断测 量结果满足上报条件。 通过该方式, 能够减少上报次数。 图 3是根据本发明实施例的用户设备的结构框图, 该用户设备包括: 分组模块 32 , 用于将测量任务分成测量任务组; 判断模块 34 , 耦合至分组模块 32 , 用于判断测量任务组内测量任务的 测量结果是否满足对应测量任务组的上报条件; 上报模块 36 , 耦合至判断模块 34 , 用于在判断模块 34的判断结果为是 的情况下, 居测量结果生成测量 4艮告, 并上 测量 4艮告。 相关技术中, UE 对于所有的测量任务均釆取触发即报的策略, 这种做 法缺乏灵活度, 并且可能增加基站处理的复杂度, 以及增加系统的开销。 本 实施例提供的用户设备, 通过分组模块 32 将全部的测量任务进行分组, 并 在判断模块 34 判断组内的测量结果满足该组对应的上报条件的情况下, 才 通过上 4艮模块 36 进行测量结果的上 4艮, 可以针对不同组配置不同的上 4艮条 件, 使得测量上报更加灵活, 并且, 在釆用合适的上报条件的情况下, 还可 以减少基站处理的复杂度, 并且能够减少系统的开销。 另外, 由 UE 自身的 分组模块 32进行分组能够节省网络侧和 UE之间的信令交互。 图 9是才艮据本发明实施例的多载波系统下测量结果的上 4艮系统的结构框 图, 包括网络侧设备 92和 UE 94 , 其中, 网络侧设备 92包括: 分组模块 96 , 用于将测量任务分成测量任务组; 指定模块 98 , 耦合至分组模块 96 , 用于 将测量任务组在测量控制消息中显式指定给 UE; UE 94包括: 判断模块 34 , 耦合至指定模块 98 , 用于判断测量任务组内测量任务的测量结果是否满足对 应测量任务组的上报条件; 上报模块 36 , 耦合至判断模块 34 , 用于在判断 模块 34 的判断结果为是的情况下, 根据测量结果生成测量报告, 并上报测 量报告。 通过该系统, 由网络侧的分组模块 96 将全部的测量任务进行分组, 并 由指定模块 98将分组指定给 UE, UE在判断模块 34判断组内的测量结果满 足该组对应的上报条件的情况下, 才通过上报模块 36进行测量结果的上报 , 可以针对不同组配置不同的上报条件, 使得测量上报更加灵活, 并且, 在釆 用合适的上报条件的情况下, 还可以减少基站处理的复杂度, 并且能够减少 系统的开销。 图 4是才艮据本发明实施例的多载波系统下测量结果的上 4艮方法的详细流 程图, 如图 4所示, 具体包括以下步骤: S401 , UE接收基站的测量配置,该测量配置中包括基站为 UE当前工作 的每个工作载波(也可以称为服务小区, 以下同此说明)各配置的两个测量 任务, 这两个测量任务的测量报告配置所配置的测量事件分别为 A1 事件和 A2事件。该测量配置中还可以包括基站配置给 UE的对应的测量对象为相邻 载波的测量任务, 这些测量任务的测量 4艮告配置所配置的测量事件为 A3 事 件和 /或 A5事件。 图 5是测量任务集的示意图, 基站在所述测量配置中通过显式配置指定 测量任务集(即上述组), 或者基站和 UE 居协议按照隐式规则制定测量任 务集, 例如, 所有的 A1 事件对应的测量任务属于一个测量任务集, 所有的 A2事件对应的测量任务属于一个测量任务集, 或者 A1和 A2事件对应的测 量任务组成一个测量任务集, 或者一个相邻载波 (测量对象) 相对不同 艮务 小区的 A3 事件组成一个测量任务集, 或者一个相邻载波(测量对象) 相对 不同月艮务小区的 A5事件组成一个测量任务集。
S402, UE 执行测量, 按照基站的测量配置进行事件评估, 并根据事件 评估的结果保存或删除测量结果, 具体地, UE 对工作载波进行测量, 并按 照基站为各个工作载波所配置的测量任务对测量结果进行 A1、A2事件评估。 UE 对相邻载波进行测量, 并按照基站为各个相邻载波所配置的测量任务对 测量结果按照所配置的测量事件 ( A3或 A5事件) 进行事件评估。 当 UE才艮据事件评估结果确定有小区的测量结果在 TTT时间内均满足该 小区所在载波上所配置的测量任务所配测量事件的进入条件且该小区尚未被 保存到对应测量任务的小区列表中时, UE 判断该小区的信号质量满足事件 进入触发条件, UE 把该小区及其测量结果本地保存到一个用对应测量任务 的 MID所标识的小区列表中。或者当 UE根据事件评估结果确定上述小区列 表中有小区的测量结果在 TTT 时间内均满足该小区所在载波上所配置的测 量任务所配测量事件的离开条件时, UE 判断该小区的信号质量满足事件离 开触发条件, UE把该小区及其测量结果从上述小区列表中删除, 同时 UE判 断经过删除操作后上述小区列表是否为空, 如果是, 则 UE从本地删除上述 小区列表。
S403 , 如果满足事件进入触发条件的测量任务属于 S401 所配置的测量 任务集, UE按照测量任务集对应的条件判断是否上报测量报告。 如图 6所 示, UE根据 S402事件评估的结果, 当 UE判断测量任务集中的第 N个载波 的信号质量满足事件进入或离开的触发条件时, UE 按照测量任务集对应的 条件判断是否上报测量报告。 上述条件对于测量任务集为测量 4艮告配置所配置的测量事件为 A1 事件 的测量任务且 N为 1时: 第一个工作载波的信号质量满足 A1事件进入触发 条件时, UE上报测量报告, 否则 UE不上报测量报告。 上述条件对于测量任务集为测量 4艮告配置所配置的测量事件为 A2事件 的测量任务为 JL N为工作或激活载波个数时: 最后一个工作或激活载波的信 号质量满足 A2事件进入触发条件时, UE上 4艮测量 4艮告, 否则 UE不上 4艮测 量报告。 上述条件对于测量任务集为测量报告配置所配置的测量事件为 A3/A5事 件的测量任务时, 且 N为 1 时: 一个相邻小区对一个服务小区满足 A3/A5 事件进入触发条件时, UE上报测量报告, 否则 UE不上报测量报告。 上述条件对于测量任务集为测量报告配置所配置的测量事件为 A3/A5事 件的测量任务, JL N为工作或激活载波个数时为: 一个相邻小区对所有 艮务 小区满足 A3/A5事件进入触发条件时, UE上报测量报告, 否则 UE不上报 测量报告。 以上测量报告中可以携带所有工作载波的信号质量。 以下通过优选实施例详细说明 UE判断是否上报测量报告的过程。
UE当前工作在两个载波上,载波 1 ( CC1 )和载波 2( CC2 );载波 3( CC3 ) 为相邻载波, 基站为 CC1和 CC2各配置了两个测量任务: 测量任务 1 ( MIDI ): 测量对象为 CC1 , 测量 4艮告配置所配置的测量事 件为 A1事件; 测量任务 2 ( MID2 ): 测量对象为 CC1 , 测量 4艮告配置所配置的测量事 件为 A2事件; 测量任务 3 ( MID3 ): 测量对象为 CC2, 测量 4艮告配置所配置的测量事 件为 A1事件; 测量任务 4 ( MID4 ): 测量对象为 CC2, 测量 4艮告配置所配置的测量事 件为 A2事件; 基站 CC3配置了两个测量任务: 测量任务 5 ( MID5 ): 测量对象为 CC3 , 测量 4艮告配置所配置的测量事 件为 A3事件, A3事件所比较的服务小区为 CC1上的服务小区; 测量任务 6 ( MID6 ): 测量对象为 CC3 , 测量 4艮告配置所配置的测量事 件为 A3事件, A3事件所比较的服务小区为 CC2上的服务小区; 为简单起见, 如图 7中纵轴上所画的两条平行于横轴的虚线所示, 個_设 以上测量任务中 A1/A2事件所配置的参数相同,即 A1事件的进入条件和 A2 事件的离开条件门限设置相同,相应的 A1事件的离开条件和 A2事件的进入 条件门限设置相同, 实际操作时也可以设置为不同。 优选实施例一 本实施例中, 描述了组的测量上 4艮条件为条件 1或 2, 且 UE釆用方式 1 或方式 3判断组内测量任务的测量结果满足对应组的测量上报条件的过程。
UE 为以上所有测量对象为工作载波且测量 4艮告配置所配置的测量事件 为 A1事件的测量任务 (即 MIDI和 MID3属于一个测量任务集)设置一个 计数器 C-Al , C-A1初始化值为 0, 最大值为所有测量 4艮告配置所配置的测 量事件为 A1事件的测量任务的总数, 本实施例中为 2。 UE为以上所有测量 对象为工作载波且测量 ^艮告配置所配置的测量事件为 A2事件的测量任务(即 MID2和 MID4属于一个测量任务集)设置一个计数器 C-A2, C-A2初始化 值为 0,最大值为所有测量 4艮告配置所配置的测量事件为 A2事件的测量任务 的总数, 本实施例中为 2。 C-A1的计数方法具体为, 当有工作载波的信号质量满足 A1事件进入触 发条件时, C-A1计数器的值加 1 ; 当有工作载波的信号质量满足 A1事件离 开触发条件时, C-A1计数器的值减 1。

Counter 1 2 1 0 1 2 1 0 以下以 T1时刻和 T4时刻为例对表 1进行说明。 Tl时刻, UE判断 CC1的信号质量满足测量任务 1所配置的 A1事件的 进入触发条件, UE把 CC1及其测量结果保存到用 MIDI所标识测量任务 1 的小区列表中, 并把计数器 C-A1的值加 1。 同时 UE根据本实施例上报工作 载波上的 A1事件的条件, 判断 UE需要上报 A1事件的测量报告, UE向基 站上 4艮测量 4艮告, 测量 4艮告中可以携带所有工作载波的测量结果。
T4时刻, UE判断 CC2的信号质量满足测量任务 3所配置的 A1事件的 离开触发条件, UE把 CC2及其测量结果从用 MID3所标识的测量任务 3的 小区列表中删除, 并把计数器 C-A1 的值减 1。 因为本实施例中 A1 事件和 A2事件的参数配置相同,因此同时 UE判断 CC2的信号质量满足测量任务 4 所配置的 A2事件的进入触发条件, UE把 CC2及其测量结果保存到用 MID4 所标识的测量任务 4的小区列表中, 并把计数器 C-A2的值加 1 , 同时 UE根 据本实施例上报工作载波上的 A2事件的条件,判断 UE需要上报 A2事件的 测量报告, UE 向基站上报测量报告, 测量报告中可以携带所有工作载波的 测量结果。 根据本实施例上报测量报告的条件, UE需要在 T1时刻和 T5时刻向基 站上报 A1事件的测量报告, 需要在 T4时刻和 T8时刻向基站上报 A2事件 的测量 4艮告, 基站可以根据 UE上 4艮的 A2/A1事件的测量 4艮告和其他 RRM 算法, 为 UE配置 /删除已经配置给 UE的异频、 异系统测量任务。 优选实施例二 本实施例仅适用于 A1事件和 A2事件参数配置相同的情况,此时 MIDI ,
MID2 , MID3和 MID4属于一个测量任务集。 以下描述组的测量上 4艮条件为 条件 1 , 且 UE釆用方式 5或 6判断组内测量任务的测量结果满足对应组的 测量上 4艮条件的过程。 在本实施例中, UE 为所有测量对象为工作载波且测量 4艮告配置所配置 的测量事件为 A1 事件或 A2 事件的测量任务设置一个计数器 Counter, Counter初始化为 0 , 最大值为所有测量 4艮告配置所配置的测量事件为 A 1事 件 (或者 A2事件) 的测量任务的总数, 本实施例中为 2。
Counter的计数方法为, 当有工作载波的信号质量满足 A1事件进入触发 条件时, Counter计数器的值加 1; 当有工作载波的信号质量满足 A2事件进 入触发条件时, Counter计数器的值减 1。 UE上报工作载波上的 A1事件的条件为, 当有工作载波的信号质量满足 A1事件进入触发条件且 Counter计数器的值为 1。
UE上报工作载波上的 A2事件的条件为, 当有工作载波的信号质量满足 A2事件进入触发条件且 Counter计数器的值为 0。 如表 1所示给出了本实施例 Counter计数器在各个时刻的计数值, 根据 本实施例上报测量报告的条件, UE需要在 T1时刻和 T5时刻向基站上报 A1 事件的测量报告,需要在 T4时刻和 T8时刻向基站上报 A2事件的测量报告。 基站可以根据 UE上报的 A2/A1事件的测量报告和其他 RRM算法, 为 UE 配置 /删除已经配置给 UE的异频、 异系统测量任务。 优选实施例三 本实施例中, 描述了组的测量上 4艮条件为条件 1或 2, 且 UE釆用方式 2 或方式 4判断组内测量任务的测量结果满足对应组的测量上报条件的过程。 本实施例中, MIDI和 MID3属于一个测量任务集, 称为测量任务集 1 , MID2和 MID4属于一个测量任务集, 称为测量任务集 2。 UE对 CC1和 CC2 的测量结果进行 A 1/A2事件评估,并根据事件评估结果把满足 A 1/A2事件进 入触发条件的工作载波保存到对应测量任务的小区列表中, 或者根据事件评 估结果把小区列表中满足 A 1/A2事件离开触发条件的工作载波从对应 ' j、区列 表中删除, 如表 1给出了基于图 7 UE工作载波信号质量变化示意图的 UE 在各个时刻的各个小区列表维护状态。 本实施例 UE上 ·ί艮工作载波上的 A1 事件的条件为, 当有工作载波的信 号质量满足 A1 事件进入触发条件, 且其他所有测量对象为工作载波且测量 报告配置所配置的测量事件为 A1 事件的测量任务没有保存的小区列表, 即 测量任务集 1中其他测量任务没有保存的小区列表时, 上报测量报告, 否则 不上 测量 4艮告。 上报工作载波上的 Α2事件的条件为, 当有工作载波的信号质量满足 Α2 事件进入触发条件, 且其他所有测量对象为工作载波且测量 4艮告配置所配置 的测量事件为 Α2事件的测量任务均有保存的小区列表, 即测量任务集 2中 其他测量任务均有保存的小区列表时, 上报测量报告, 否则不上报测量报告。 根据表 1所示的 UE在各个时刻的小区列表状态, 本实施例中, UE需要 在 Tl时刻和 T5时刻向基站上 4艮 A1事件的测量 4艮告, 需要在 Τ4时刻和 Τ8 时刻向基站上报 Α2事件的测量报告。 基站可以根据 UE上报的 A2/A1事件 的测量艮告和其他 RRM算法, 为 UE配置 /删除已经配置给 UE的异频、 异 系统测量任务。 优选实施例四 本实施例中, 描述了组的测量上 4艮条件为条件 3 , 且 UE釆用方式 7判 断组内测量任务的测量结果满足对应组的测量上 4艮条件的过程;和 /或条件 5 , 且 UE釆用方式 9判断组内测量任务的测量结果满足对应组的测量上报条件 的过程。 本实施例中, UE对 CC3测量结果进行 A3事件评估, MID5和 MID6是 的测量对象都是 CC3 , 报告配置的触发类型都为 A3事件, 比较的参考服务 小区不同, 分另 为 CC1和 CC2, 属于一个测量任务集。 测量任务集使用的上 报条件为当有一个相邻小区对一个参考服务小区的测量任务满足 A3 事件进 入触发条件后, 判断测量任务集中其他测量任务的小区列表中不存在该相邻 小区或者小区列表不存在时(即条件 3方式 7 ), 进行上报, 否则不上报。 即 一个相邻小区只对第一个服务小区满足 A3 事件进入触发条件时进行上报, 其它时间不上报。 所述参考服务小区是 A3 事件中所对比的服务小区, 所以 同理 A5也可以使用相同的方法。 优选的, 为了更好的辅助基站进行载波管理, 在上述条件 3的基础上, 测量任务集使用的上报条件, 还可以根据 A3 事件的离开触发条件设置, 即 当测量任务集中有测量任务的小区列表中的一个相邻小区满足 A3 事件的离 开触发条件时后, 判断测量任务集中其他所有测量任务的小区列表中不存在 该相邻小区或者小区列表不存在时(即条件 5方式 9 ), 进行上报, 否则不进 行上报。 即测量任务集中部分或者全部测量任务的小区列表中存在的一个相 邻小区都满足所述部分或者全部测量任务的 A3事件的离开触发条件时上报, 其他时间不上 4艮。 如图 8所示,ΤΙ时刻 CC3的信号质量比 CC1的信号质量好一个偏移量, 满足 MID5所对应的 A3事件的进入触发条件, UE将 CC3及其测量结果保 存到 MID5对应的小区列表中, 并检查相同测量任务集中的 MID6的小区列 表。 此时 CC2的信号质量远好于 CC3的信号质量, 所以 MID6无小区列表, 或者小区列表中没有 CC3 , UE上报测量报告。 当到达 Τ2时刻, CC3的信号 质量又比 CC1的信号质量差了, 此时满足对应 A3事件的离开触发条件, UE 将 MID5 对应的小区列表中的 CC3 及其测量结果删除, 优选的, UE检测 MID6无小区列表, 或者小区列表中没有 CC3 , UE上报测量报告。 到达 T3 时, 和 T1时刻分析一样, UE又再次满足 MID5对应的 A3事件的进入触发 条件, 上 4艮 CC3的测量 4艮告。 T4时, CC3满足 MID6对应的 A3事件的进入 触发条件, 此时 CC3 已经在 MID5对应的小区列表中, 所以 T4不进行测量 报告上报。 T5时刻, CC3的信号质量又比 CC2的信号质量差了, 此时满足 对应 A3事件的离开触发条件, UE将 MID6对应的小区列表中的 CC3及其 测量结果删除。 T6时刻, CC3的信号质量又比 CC1的信号质量差了, 此时 满足对应 A3事件的离开触发条件, UE将 MID5对应的小区列表中的 CC3 及其测量结果删除, 优选的, UE检测 MID5 无小区列表, 或者小区列表中 没有 CC3 , UE上 4艮测量 4艮告。 基站可以 -据 UE上 4艮的上述 A3事件的测量 4艮告和其他 RRM算法,进 行载波管理, 比如在 T1时刻和 T3时刻, 基站可以为 UE添加(配置) CC3 , 使其成为 UE的工作载波; 在 T2和 T6时刻, 基站可以 4巴 CC3从 UE的工作 载波中删除。 优选实施例五 本实施例中, 描述了组的测量上 4艮条件为条件 4, 且 UE釆用方式 8判 断组内测量任务的测量结果满足对应组的测量上 4艮条件的过程;和 /或条件 6, 且 UE釆用方式 10判断组内测量任务的测量结果满足对应组的测量上报条件 的过程。 本实施例中, UE对 CC3测量结果进行 A3事件评估, MID5和 MID6是 的测量对象都是 CC3 , 报告配置的触发类型都为 A3事件, 参考比较的服务 小区不同, 分另 为 CC1和 CC2, 属于一个测量任务集。 测量任务集使用的上 报条件为当有一个相邻小区对一个参考服务小区的测量任务满足 A3 事件进 入触发条件后, 判断测量任务集中所有测量任务的小区列表中都存在该相邻 小区时(即条件 4方式 8 ), 进行上 4艮, 否则不上 4艮。 即相邻小区只对所有配 置的参考月艮务小区都满足 A3 事件时进行上 4艮, 其它时间不上 4艮。 所述参考 服务小区是 A3事件中所对比的服务小区,所以同理 A5也可以使用相同的方 法。 优选的, 为了更好的辅助基站进行切换判决, 在上述条件 4的基础上, 测量任务集使用的上报条件, 还可以根据 A3 事件的离开触发条件设置, 即 当测量任务集中有测量任务的小区列表中的一个相邻小区满足 A3 事件的离 开触发条件时后, 判断测量任务集中其他所有测量任务的小区列表中都存在 该相邻小区时 (即条件 6方式 10 ), 进行上 ·ί艮, 否则不进行上 ·ί艮。 即测量任 务集中所有测量任务的小区列表中均存在的相邻小区满足一个测量任务的 A3事件的离开触发条件时上 4艮, 其他时间不上 4艮。 如图 8所示, T1时刻 CC3的信号质量比 CC1的信号质量好于一个偏移 量, 满足 MID5所对应的 A3事件的进入触发条件, UE将 CC3及其测量结 果保存到 MID5对应的小区列表中, 并检查相同测量任务集中的 MID6的小 区列表。 此时 CC2的信号质量远好于 CC3的信号质量, 所以 MID6无小区 列表, 或者小区列表没有 CC3 , UE不上报测量报告。 当到达 Τ2时刻, CC3 的信号质量又比 CC1差了, 此时满足对应 A3事件的离开触发条件, UE将 MID5对应的小区列表中的 CC3删除。 到达 Τ3 时, 和 T1 时刻分析一样, UE又再次满足 MID5对应的 A3事件的进入触发条件, 仍然不上 4艮 CC3的 测量报告。 Τ4时, CC3的信号质量满足 MID6对应的 A3事件的进入触发条 件, 此时 CC3已经在 MID5对应的小区列表中, 所以 Τ4进行 CC3的测量 4艮 告上 ·ί艮。 Τ5时刻, CC3的信号质量又比 CC2的信号质量差了, 此时满足对 应 A3事件的离开触发条件, UE将 MID6对应的小区列表中的 CC3及其测 量结果删除。 Τ6时刻, CC3的信号质量又比 CC1的信号质量差了, 此时满 足对应 A3事件的离开触发条件, UE将 MID5对应的小区列表中的 CC3及 其测量结果删除, 优选的, UE检测 MID5 无小区列表, 或者小区列表中没 有 CC3 , UE上报测量报告。 基站可以 -据 UE上 4艮的上述 A3事件的测量 4艮告和其他 RRM算法,进 行切换判决, 比如在 Τ4时刻, 基站可以把 UE切换到 CC3上, 如果在 Τ4 时刻基站没有把 UE切换到 CC3上, 则在 Τ6时刻之后, 基站判断 CC3不再 是合适的切换候选小区, 不能再把 UE切换到 CC3上。 需要说明的是, 以上所有实施例中为描述方便, CC1 的测量结果均指 UE在 CC1上的服务小区的测量结果, CC2的测量结果均指 UE在 CC2上的 服务小区的测量结果, CC3 的测量结果均指 CC3 上一个相邻小区的测量结 果。 综上所述, 以上实施例提供的方案在多载波系统下, 可以减少测量 4艮告 数量, 减少系统开销, 同时基站可以直接利用 UE上报的测量报告判断是否 为 UE配置异频 /异系统测量或者进行切换判, 减少了基站处理的复杂度。 需要说明的是, 在附图的流程图示出的步骤可以在诸如一组计算机可执 行指令的计算机系统中执行, 并且, 虽然在流程图中示出了逻辑顺序, 但是 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。 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, 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 ^"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。
