实施本发明的方式
本发明实施例提供了一种基于多载波***的测量上报方法、 ***、 网络侧设备及终端， 终端 接收网络侧发送的测量控制消息， 该测量控制消息中包含主载频和辅载频的测量信息， 根据上述测 量控制消息对上述主载频和辅载频进行测量， 并将测量结果与对应的载频上报至上述网络侧。
为了使本技术领域的人员更好地理解本发明实施例提供的技术方案， 下面结合附图和具体实 施方式对本发明实施例提供的技术方案作进一步的详细说明。
实施例一
本实施例提供的基于多载波的测量上报方法的流程如图 1所示， 本实施例示出了终端接入网络 侧时的测量上报过程， 具体步骤如下：
步骤 101 : 接收网络侧发送的测量控制消息， 该测量控制消息中包含主载频和辅载频的测量信 息
其中， 测量控制消息包括主载频的频点信息， 主载频的频内测量信元， 辅载频的频内测量信 元， 辅载频的各信元对应载频的频点信息。
特别的， 当上述辅载频的测量结果对移动性判决无关时， 上述测量控制消息指示不对辅载频 步骤 102： 根据测量控制消息对主载频和辅载频进行测量。
其中， 对主载频和辅载频进行测量包括进行频内测量和频间测量。
步骤 103 : 将测量结果及与该测量结果对应的载频上报至网络侧。
其中， 测量结果至少包括所有使用的主载频小区的信号质量和所有使用的辅载频小区的信号 质量。
需要说明的是， 当步骤 101的测量控制消息进指示不对辅载频进行测量时， 则步骤 102中不必 对辅载频进行测量， 相应的， 上述步骤 103中上报的测量结果中也不包含辅载频小区的信号质量。
由上述实施例可见， 终端可以同时对主载频和辅载频进行频内测量， 网络侧可以根据辅载频 的测量结果对与辅载频相关的信息进行维护， 提高了多载波***中的网络侧对终端侧移动性判决的 准确性。 实施例二
本实施例提供的基于多载波的测量上报方法流程如图 2所示， 与实施例一相比， 本实施例进一 步示出了终端接入网络侧后的测量上报过程， 具体步骤如下：
步骤 201 : 接收网络侧发送的测量控制消息， 该测量控制消息中包含主载频和辅载频的测量信 息
其中， 测量控制消息包括主载频的频点信息， 主载频的频内测量信元， 辅载频的频内测量信 元， 辅载频的各信元对应载频的频点信息。
步骤 202: 根据测量控制消息对主载频和辅载频进行测量。
具体的， 对终端所有正在使用的主载频和辅载频对应的小区进行测量， 获得上述小区的信号 质量， 并评估是否满足测量事件上报条件。
步骤 203 : 将测量结果及与该测量结果对应的载频上报至网络侧。
具体的， 向上述网络侧上报上述主载频小区的信号质量， 并根据上述主载频小区的信号质量 向网络侧上报用于主载频激活集维护、 最好小区维护及对未使用载频进行测量的事件。
向上述网络侧上报上述辅载频小区的信号质量， 并当上述辅载频小区的信号质量低于门限值 时， 向网络侧上报 2d事件， 当上述辅载频小区的信号质量高于门限值时， 向网络侧上报 2庫件； 或 者向上述网络侧上报上述辅载频小区的信号质量， 并根据上述辅载频小区的信号质量向网络侧上报 用于辅载频激活集维护、 最好小区维护， 及对未使用载频进行测量的事件。
其中， 各种测量结果以与其对应的事件方式上报至网络侧， 首先介绍测量上报过程中涉及的 各种事件， 这些事件包括 lx事件， 即各种频内测量事件的总称， 和 2x事件， 即各种频间测量事件的 总称。 其中， lx事件进一步细分为： la事件， 表示一个主导频信号质量高于一个相对门限； lb事件， 表示一个主导频信号质量低于一个相对门限； lc事件， 表示一个非激活集主导频信号质量高于一个 激活集主导频信号质量； Id事件， 表示最好小区变更； le事件， 表示一个主导频信号质量高于一个 绝对门限； lf»件， 表示一个主导频信号质量低于一个绝对门限。 其中， 2x事件进一步细分为： 2a 事件， 表示最好频率变更； 2b事件， 表示当前使用的载频信号质量低于一个绝对门限， 而未使用的 一个频率信号质量高于一个绝对门限； 2c事件， 表示一个未使用的频率信号质量高于一个绝对门限; 2d事件， 表示当前使用的频率的信号质量低于一个绝对门限； 2f»件， 表示当前使用的频率信号质 量高于一个绝对门限。
步骤 204: 判断主载频或辅载频的信号质量是否低于门限值， 若是， 则执行步骤 205 ; 否则， 结束流程， 即不执行对非使用载频进行测量的流程。
需要说明的是， 在辅载频的信号质量低于门限值时， 也可以不执行对非使用载频进行测量的 流程。
步骤 205: 接收网络侧发送的对非使用载频进行测量的测量控制消息。
步骤 206: 收发信机对非使用载频进行测量。
由于终端在对非使用载频进行测量时， 要遵循一个载频不能被多个收发信机测量的原则， 这 个原则是为了避免多个收发信机对同一个非使用载频进行测量， 从而导致对该非使用载频的重复测 量。 因此， 终端的各个收发信机均可以对未使用载频进行测量， 但是一个非使用载频在一段时间内 只能被一个收发信机测量， 也就是说， 在一段时间内可以只用一个收发信机对所有非使用载频进行 测量， 即如果终端有空闲的收发信机， 则在空闲收发信机中选择一个对非使用载频进行测量， 如果 终端没有空闲的收发信机， 则选择一个正在使用的收发信机， 启动压缩模式后对非使用载频进行测 具体的， 空闲的收发信机对上述非使用载频进行测量； 或对应上述主载频的收发信机启动压 缩模式后对上述非使用载频进行测量； 或对应上述辅载频的任一收发信机启动压缩模式后对上述非 使用载频进行测量； 或对应上述主载频的收发信机、 对应上述辅载频的收发信机和空闲收发信机分 别对不同的非使用载频进行测量。
步骤 207: 将非使用载频的测量结果发送至网络侧。
具体的， 当上述非使用载频的信号质量高于门限值， 而使用载频的信号质量低于上述门限值 时， 上报 2b事件； 或当上述非使用载频的信号质量高于门限值时， 上报 2c事件。
由上述实施例可见， 终端除了可以对主载频进行频内测量外， 还可以对与该终端正在使用的 所有辅载频进行频内测量， 以及对非使用载频进行测量， 网络侧可以根据辅载频的测量结果及非使 用载频的测量结果对相关信息进行维护， 相应提高了多载波***中的网络侧对终端侧移动性判决的 准确性。 实施例三
本实施例提供的基于多载波的测量上报方法的流程如图 4所示， 本实施例将结合如图 3所示的 针对双载波 HSDPA***应用场景进行描述， 图 3所示的组网结构示意图中，终端是具有多载波能力的 终端， 小区 1和小区 3的频点为 fl， 小区 2和小区 4的频点为 f2， 小区 1 (fl为主载频）和小区 2 (G为辅 载频）进行多载波配对， 小区 3和小区 4进行多载波配对， 上述两组配对的小区应用于下行 HS-DSCH 中， 属于同一个基站， 且使用同一根发射天线。 下面详细描述将本发明方法实施例应用在双载波 HSDPA***中时， 终端进行测量上报的过程：
步骤 401 : 终端接入网络。
步骤 402: 网络侧向终端发送测量控制消息， 例如 Measurement Control。
网络侧可以在该 Measurement Control消息中增加相关域， 用于标识如下信息： 终端使用的主载 频； 对于终端使用的主载频和辅载频， 均分别构造一个同频测量信元； 指明同频测量的频率； 将未 使用载频的小区放到异频测量小区列表。
具体的， 在 Measurement Control消息的主载频信元 （例如 Primary Frequency) 中填充主载频 fl 的信息， fl和 S中分别有频内测量信元 （例如 intra-frequency measurement) 两个信元通过载频信息 fl和 β进行区分， 其中 f2的 intra-frequency measurement信元中的小区测量列表， 例如 cells for measurement中仅包含 f2的服务小区，且仅进行频间测量事件的上报，而不进行频内测量事件的上报； 在频间测量信元（例如 inter-frequency measurement)中的频间测量报告事件信元（例如 inter-frequency measurement reporting criteria) 中仅包含 2a、 2d、 2庫件。
步骤 403 : 终端根据接收到的测量控制消息中相关域增加的内容对正在使用的主载频和辅载频 进行频内和频间测量。
终端接收到 Measurement Control消息后， 通过两个收发信机分别测量主载频 fl对应的主载频小 区， 以及辅载频 G对应的辅载频小区。
其中， 主载频 fl上报事件规则跟现有频内测量、 频间测量规则相同， 即根据小区 1的信号质量 上报 lx事件、 2d事件和 2f»件， 供网络侧进行激活集的维护、 最好小区的维护和启动对未使用载频 辅载频 β根据小区 2的信号质量上报 2d事件和 2f»件， 用于对辅载频进行添加和删除。 由于辅 载频只有 HSDPA相关链路， 不需要维护激活集， 因此不必上报 la事件、 lb事件和 lc事件。 由于现有 双载波 HSDPA***中， 配对的主载频服务小区和辅载频服务小区只能使用一根天线， 而一根天线在 一个载频上不能发射两个小区信号， 因此不可能出现主载频服务小区保持不变， 而辅载频进行同频 服务小区更新的情况， 所以辅载频 f2不必上报 Id事件。
步骤 404: 终端根据不同的测量结果触发测量事件上报。
在测量事件触发后进行测量报告上报时， 至少上报所有使用载频的小区的信号质量， 即至少 上报主载频 fl上测量的小区， 以及辅载频 G上测量的小区的信号质量。
其中， 主载频 fl根据频内测量结果上报频内测量事件， 以供主载频做激活集维护和服务小区的 更新。若主载频 fl和辅载频 G中最好载频发生了变化， 则上报 2a事件， 相应测量报告中包含新的最好 载频的信息和前次最好载频的信息； 当主载频 fl或辅载频 G的信号质量低于一定的门限时， 上报 2d 事件； 当主载频 fl或辅载频 G的信号质量高于一定门限时， 上报 2f»件。
步骤 405: 网络侧确认终端主载频上报了 2d事件。
步骤 406: 网络侧向终端下发针对 2d事件的测量控制消息。 由于终端上报了针对主载频 fl的 2d事件， 此时主载频 fl的信号质量低于一定门限， 所以网络侧 向终端下发新的测量控制消息， 请求终端对非使用频率进行测量。 同时， 频内测量保持不变。
具体的， 在 inter-frequency measurement信元中的 inter-frequency reporting criteria信元中包含 2a 事件、 2b事件、 2c事件、 2d事件和 2谆件， 测量的非使用载频小区的范围不限于与主载频 fl服务小区 1配对的服务小区 2。
步骤 407: 终端根据收到的测量控制消息进行非使用频率的测量。
终端收到 Measurement Control消息后， 通过两个收发信机分别测量主载频 fl对应的主载频小 区， 以及辅载频 G对应的辅载频小区。
终端可以在主载频 fl对应的收发信机或辅载频 β对应的收发信机上启动压缩模式，对非使用载 频进行测量。 由于 FDD***每个收发信机在一个时刻只能工作在一个载频上， 因此如果要使用该收 发信机测量其它载频的信号， 就要启动压缩模式。 并且， 由于一段时间内一个载频不允许被多个收 发信机测量， 以避免被重复测量。 因此， 在进行非使用载频的测量时， 可以只使用一个收发信机进 行所有非使用载频的测量，即通过主载频 fl收发信机或辅载频 S收发信机中的一个对非使用载频进行 测量；也可以通过主载频 fl收发信机和辅载频 s收发信机同时对不同的非使用载频进行测量，测量时 需要保证不对同一个非使用载频进行重复测量。
步骤 408: 终端根据非使用载频的测量结果触发频间测量事件上报。
终端根据对非使用载频的测量结果， 向网络侧上报 2b事件和 2c事件。 同时， 终端还可以向网络 侧上报对应主载频 fl和辅载频 β的频间测量事件， 包括 2a事件、 2d事件、 2f»件等。
由上述实施例可见， 终端可以对正在使用的所有辅载频进行频内测量， 网络侧可以根据辅载 频的测量结果对与辅载频相关的信息进行维护， 提高了多载波***中的网络侧对终端侧移动性判决 的准确性。 实施例四
本发明实施例除了可以应用在双载波 HSDPA***中， 还可以应用在上行和下行均为多载波的 ***中， 例如， 下行 m个载波， 上行 n个载波的场景， 其中， m大于 2、 n大于 2， 并且 m大于等于 n。 如图 5所示， 本实施例详细描述了将本发明方法实施例应用在多载波***中时， 终端进行测量上报的 过程。 在该多载波***中， 与主载频配对的辅载频可以有多个， 上行和下行均有成对载频的辅载波 需要维护激活集， 与主载频服务小区配对的辅载频服务小区也相应有多个， 因此本实施例与实施例 三的不同在于， 需要辅载频上报 lx事件。
步骤 501 : 终端接入网络。
步骤 502: 网络侧向终端发送测量控制消息， 例如 Measurement Control。
该测量控制消息中包含主载频的频点信息； 对于主载频和每个辅载频均有一个频内测量信元； 在每个频内测量信元中标明载频信息； 将未使用载频的小区写入频间测量小区列表。
需要说明的是， 为了优化测量过程， 网络侧可以根据多载波小区配对关系减少无用的测量， 即在测量控制消息中辅载频的测量小区列表中仅包含与主载频服务小区配对的辅载频服务小区， 而 不包含其它未配对的辅载频服务小区。
如果辅载频触发的事件对网络侧进行移动性判决没有影响时， 在测量控制消息中也设置不上 报相应事件。 例如， 当终端上行使用一个主载频， 在辅载频上只有 HSDPA信道， 由于 HSDPA信道不 需要维护激活集， 因此可以在测量控制消息中设置不上报 la事件、 lb事件、 lc事件； 如果两个事件 同时触发或者触发事件的间隔小于一定门限时， 要求将两个事件的测量结果放在一个测量报告中发 送， 以此减少上报的测量报告。
步骤 503： 终端对正在使用的主载频和辅载频进行频内测量和频间测量。
主载频进行频内测量和频间测量，即根据主载频小区的信号质量上报 lx事件、 2d事件和 2f»件， 以供网络侧进行激活集的维护， 最好小区的维护和启动未使用频率的测量。
辅载频同样进行频内测量和频间测量， 即根据辅载频小区的信号质量上报 lx事件、 2d事件和
2蹿件， 以供网络侧进行激活集维护、 最好小区的未和启动未使用载频的测量。
步骤 504: 终端向网络侧上报包含测量结果的测量报告。
对测量控制消息中指定的需要测量的载频小区进行测量后， 测量报告中包含相应的事件以及 与该事件对应的载频。 其中， lx事件、 2d事件和 2f»件只与各使用载频有关； 2b事件与各正在使用 的载频和某个非使用载频有关； 2c事件与非使用载频有关； 2a事件与当前的最好载频和将要取代该 最好载频的一个非最好载频有关， 其中要取代最好载频的载频可以是正在使用的载频， 也可以是非 使用载频。
具体的， 在包含终端正在使用的载频小区测量结果的频内测量结果列表 （例如 intra-frequency measured results list) 中， 增加载频信息， 用以区分正在使用的载频和未使用的载频； 在频间测量事 件结果（例如 inter-frequency measurement event results) 中增加触发载频的信息。 由于有多个辅载频， 因此还需要在频内测量事件结果（例如 intra-frequency measurement event results)中增加触发载频的信 息， 其中， 对于 2a事件， 在触发载频的信息中写入原来的最好载频； 对于 2b事件， 在触发载频的信 息中写入正在使用的某个载频， 该载频低于一定的门限； 对于 2c、 2d和 2f»件， 在触发载频的信息 中不写入任何载频。
如果终端上报的测量报告中包含 2d事件的话， 网络侧还需要向终端下发对非使用载频进行测 量的测量控制消息， 其过程与实施例三一致， 在此不再赘述。

本实施例提供的基于多载波的测量上报方法， 如图 11所示， 具体步骤如下：
步骤 1101 :接收网络侧发送的测量控制消息，该测量控制消息中包含主载频和辅载频对应小区 的测量信息， 以及邻区的测量信息和变更最好小区事件 （gPld事件） 的触发条件。
本发明实施例对现有 Id事件的触发条件进行了优化， 本发明实施例中 Id事件的触发条件包括 以下几种场景：
场景一： 支持 DC (dual cell, 双小区） 的 UE当前只使用了一个频点， 这种情况可能是 UE的服 务小区不是多载波小区 （也称扇区， sector)或者高层没有配置该 UE使用 DC技术。 该 UE的邻区中同 时存在多载波小区和单载波小区， 假设 UE当前使用的频点为 fl， 它的邻区中的多载波小区可以使用 的频点为 fl和 f2， 并且测量量为路径损耗 pathloss, 则该多载波小区 Id事件的触发条件为该多载波小 区在两个频点 fl和 G上的测量结果同时满足下述公式 1和 2， 或者同时满足公式 1和 3
公式 1 : 10LogMNotBeSt>fl + CIONotBest>fl≤ 10LogMBest>fl + CIOBestjfl - Hlld/2 公式 2: lOLogM est,fl + CIONotBestjfl≤ 10LogMBest>fl + CIOBest>fl - H2ld/2 公式 3 : 10LogMNotBeSt> s + CIONotBest>s≤ 10LogMBest fl + CIOBes^ - H2ld/2
如果测量量为 RSCP (接收信号码功率） 或 Ec/NO (信号干扰比）， 则上述公式 1 2、 和 3分别 替换为：
公式 1 10L°gMNotBeSt>fl + CIONotBestjfl > 10LogMBest>fl + CIOBest>fl + Hlld/2 公式 2，： 10L gM + CIO est, fl≥10LogMBest> fl + CIOBest,fl + H2ld/2 公式 3 10LogM ≥ 10LogMBestjfl + CIOBestjfl + H2ld/2
上述多载波小区 Id事件的触发条件为该多载波小区在两个频点 fl和 f2上的测量结果同时满足 上述公式 Γ和 2'， 或者同时满足公式 Γ和 3'。
其中， MN。fflest，fl表示当前非最好 sector在频点 fl 的测量结果； eiON。tBest>fl表示当前非最好 sector在频点 fl上的小区偏置； MN°tBest ^表示当前非最好 sector在频点 G上的测量结果； 。^^^ 表示当前非最好 sector在频点 S上的小区偏置； MBest>fl表示当前最好 sector在频点 fl上的测量结果； CI°Best>fl：表示当前最好 sector在频点 fl上的小区偏置； Μβ^Ω表示当前最好 sector在频点 f2上的测量 结果； eiOBest^表示当前最好 sector在频点 £2上的小区偏置。 H1 ld和 H2 ld表示 id事件的迟滞参数。
Hlld的作用是保证切换不会影响主载波的信号质量， 因为上行链路只使用主载波， 需要保证切换后 的新小区在主载波上的信号质量不低于原有小区， H2ld的作用是保证新小区或 sector至少在一个下 行频点上的信号质量比原有小区好的程度高于一个门限， 这样才能保证切换对用户的下行业务质量 有好处。 因此 H 1ld小于等于1 ^13。 另外需要说明的是， 当测量量为 RSCP时， M>«BeSt，fl、 MNotBest,f2 ^ M BeSt>fl和 M BeSt>£2的单位 是毫瓦 mW。
场景二： 支持 DC的 UE当前的服务小区是多载波小区而且 UE当前使用了 DC技术， 它的邻区中 同时存在多载波小区和单载波小区， 假设 UE当前使用的频点为 fl和 f2， 主载波为 fl， 它的邻区中的 多载波小区可以使用的频点为 fl和 f2， 它的邻区中的单载波小区可以使用的频点为 fl或者 f2。
如果测量量为路径损耗，贝 U使用 fl的单载波小区 Id事件的触发条件为该小区在 fl频点上的测量 结果满足上述公式 2; 使用 S的单载波小区 Id事件的触发条件为该小区在 G频点上的测量结果满足上 述公式 3。
如果测量量为 RSCP或 Ec/NO,则使用 fl的单载波小区 Id事件的触发条件为该小区在 fl频点上的 测量结果满足上述公式 2' ;使用 G的单载波小区触发 Id事件的条件为该小区在 G频点上的测量结果满 足上述公式 3'。
使用频点 fl和 G的多载波小区 Id事件的触发条件与场景一相同， 此处不再赘述。
场景三： 支持 DC的 UE当前的服务小区是多载波小区而且 UE当前使用了 DC技术， 它的邻区中 同时存在多载波小区和单载波小区， 假设 UE当前使用的频点为 fl和 f2， 主载波为 fl， 它的邻区中的 多载波小区可以使用的频点为 fl和 β， 或者 £2和 。 如果测量量为路径损耗， 则使用 fl和 β的 sector Id事件的触发条件为该小区在 fl频点上的测量 结果满足上述公式 2;使用 G和 β的 sector Id事件的触发条件为该小区在 S频点上的测量结果满足上述 公式 3。
如果测量量为 RSCP或 Ec/NO, 则使用 fl和 f2的 sector Id事件的触发条件为该小区在 fl频点上的 测量结果满足上述公式 2'； 使用 S和 β的 sector Id事件的触发条件为该小区在 f2频点上的测量结果满 足上述公式 3'。
步骤 1102: 根据测量控制消息对主载频和辅载频对应小区， 以及邻区进行测量。
具体的， 对终端所有正在使用的主载频和辅载频对应的小区， 以及邻区进行测量， 获得上述 小区的信号质量， 并根据上述 Id事件的测量上报条件判断是否上报 Id事件。
步骤 1103 : 如果满足步骤 202中 Id事件的触发条件， 将测量结果、 与该测量结果对应的载频以 及与该测量结果对应的 Id事件上报至网络侧。
由本实施例可见， 优化后的 Id事件能让 UE更有效的上报测量报告， 提高网络侧对终端侧移动 性判决的准确性。 本领域普通技术人员可以理解实现上述实施例方法中的全部或部分步骤是可以通过程序来指 令相关的硬件来完成， 上述的程序可以存储于一计算机可读取存储介质中， 该程序在执行时， 包括 如下步骤： 接收测量控制消息， 上述测量控制消息中包含主载频和辅载频的测量信息； 根据上述测 量控制消息对上述主载频和辅载频进行测量； 上报测量结果及与上述测量结果对应的载频。 上述的 存储介质， 如： ROM/RAM、 磁碟、 光盘等。
