一种测量上报的方法和装置
本申请要求 2008年 9月 28日递交的申请号为 200810169224. X、 发明名 称为 "一种测量上报的方法和装置" 的中国专利申请的优先权, 其全部内容 通过引用结合在本申请中。
技术领域
本发明实施例涉及通信领域, 尤其涉及一种测量上报的方法和装置。
背景技术
2007年在瑞士日内瓦召开的世界无线电通信大会(WRC07)上, 国际电信 联盟(ITU)划定了第三代及***移动通信***的四个新频段, 即 3. 4G〜3. 6GHz的 200MHz带宽、 2. 3G〜2. 4GHz的 100MHz带宽、 698M〜806MHz的 108MH z带宽和 450M〜470MHz的 20MHz带宽。 但由于在不同国家的分配情况不同, 每个运营商最终获得的 IMT频段很可能并不连续, 因此为了保证高带宽、 高 速业务的服务质量, 频谱聚合技术需求被引入 LTE-A (Long Term Evolution -Advanced, 长期演进)***中。频谱聚合可以应用在连续和非连续的频段上。
在激活态移动性管理中, 网络侧为 UE (User Equipment ) 配置测量频点 作为测量目标, UE在配置的频点上搜索小区, 对其搜索到的小区进行测量。 U E得到测量结果后, 如何将测量结果上报给网络侧, 有两种方式: 周期性上报 和事件触发的上报。 本发明中涉及的是事件触发的上报方式。 事件触发的上 报方式指网络侧定义了多种测量上报事件,服务小区为每个连接态 UE在 RRC Connection Reconfiguration中配置或修改测量事件。如果 UE的测量结果满 足测量事件要求, 触发了测量结果上报, 通过测量报告将满足测量事件要求 的测量结果上报给服务小区, 服务小区根据其测量结果和相关无线资源管理 算法 (RRM) 做出切换决定。
在 LTE***中, 测量事件分为两种:
EUTRA***测量事件 (包括同频与异频) :
A1事件: 服务小区信号质量高于绝对阈值;
A2事件: 服务小区信号质量低于绝对阈值;
A3事件: 相邻小区信号质量比服务小区高一个偏置值;
A***: 相邻小区信号质量高于绝对阈值;
A5事件: 服务小区信号质量低于绝对阈值 1, 并且相邻小区信号质量高 于绝对阈值 2;
异***测量事件:
B1事件: 相邻小区信号质量高于绝对阈值;
B2 事件: 服务小区信号质量低于绝对阈值 1, 并且相邻小区信号质量高 于绝对阈值 2;
月艮务小区对 UE在 RRC Connection Reconfiguration消息的 measuremen t Configuration 信元中配置测量事件, 包括配置测量事件的名称及相关阈 值。
对于服务小区为聚合小区的情况, 新增加了一个需求是 LTE-A UE可以在 多个频带上同时接收和发送数据。 不同频率层之间的衰减不同, 聚合载波之 间覆盖范围有差异, 当 UE当前接收和发送数据频带信号质量下降时, 或当前 非服务频带的信号质量好于当前服务频带时, 网络侧需要能够通过 UE上报事 件及时更换工作频带, 进而保证 UE数据正确、 高效传输。
在实施本发明的过程中, 发明人发现现有技术中至少存在以下问题: 频谱聚合场景下, 现有的测量事件不能支持 UE对于聚合服务小区和相邻 小区测量结果全面的上报。 发明内容
本发明实施例提供一种测量上报的方法和装置, 以实现 UE在聚合小区中 全面的测量和上报测量结果, 从而保证当前服务频带具有高质量的信号, 保 证 UE数据正确、 高效传输。
本发明实施例提供一种测量上报的方法, 包括以下歩骤:
测量服务小区及相邻小区的频带信号质量; 当所述服务小区及相邻小区 的频带信号质量满足测量事件要求时
向所述服务小区上报满足所述测量事件的频带信号质量。
本发明实施例提供一种测量上报的装置, 包括:
测量单元, 用于测量服务小区及相邻小区的频带信号质量;
上报单元, 用于当所述服务小区及相邻小区的频带信号质量满足测量事 件要求时, 向所述服务小区上报满足所述测量事件的频带信号质量。
与现有技术相比, 本发明实施例至少具有以下优点:
通过用户设备配置多频带测量事件, 对频谱聚合服务小区及相邻小区进 行全面的测量, 并上报满足测量事件要求的频带信号质量, 使当前服务频带 具有高质量的信号。 附图说明
为了更清楚地说明本发明实施例的技术方案, 下面将对实施例中所需要 使用的附图作简单地介绍, 显而易见地, 下面描述中的附图仅仅是本发明的 一些实施例, 对于本领域普通技术人员来讲, 在不付出创造性劳动性的前提 下, 还可以根据这些附图获得其他的附图。

下面结合附图和具体实施例对本发明进行介绍。
本发明实施例提供一种测量上报的方法, 如图 1所示, 包括以下歩骤: 歩骤 slOl , 测量服务小区及相邻小区的频带信号质量; 当服务小区及相 邻小区的频带信号质量满足测量事件要求时, 执行歩骤 sl02。
歩骤 sl02, 向服务小区上报满足上述测量事件的频带信号质量。
通过采用本发明实施例提供的方法, 用户设备配置多频带测量事件, 对 频谱聚合服务小区及相邻小区进行全面的测量, 并上报满足测量事件要求的 频带信号质量, 使当前服务频带具有高质量的信号。 下面结合具体应用场景对本发明进行进一歩介绍。
本发明实施例提供一种测量上报的方法, 对于聚合场景, 即服务小区或 相邻小区为聚合小区的情况, 需要对现有技术中的测量事件进行修改或增加 新的测量事件, 以全面上报服务小区及相邻小区频带的信号质量。
具体的, 如图 2所示, 包括以下歩骤:
歩骤 s201, 配置频谱聚合服务小区服务集内与服务集外的频带信号质量 测量事件;
对服务小区为聚合小区时, UE当前使用的收发数据频带进行测量, 当 UE 当前收发数据频带信号质量下降时, 进行小区内频带切换。
对于服务小区为聚合小区的情况, 定义了服务集(Serving Set )的概念, 服务集即 UE保存同时监听 PDCCH信道的频率集合, Serving Set可以包含一 个主频率或多个频率。
当 Serving Set仅包含一个主频带时, 即聚合小区采用一个主频带其它 为辅频带的方式, 需要新增加测量事件将信号质量较好的频带作为服务小区 主频带。 当主频带信号质量下降时, 上报测量事件, 通过服务小区更换主频 带, 保证该 UE能够高质量的接收数据。
当 Serving Set中包含多个频带时, 即 UE可以同时监听服务小区中的某 些频带,需要新增加测量上报事件,在当前 UE收发数据频带信号质量下降时, 上报测量事件, 通过服务小区更换频带, 从而保证该 UE能够高质量的接收数 据。
Serving Set仅包含一个主频带可以看做 Serving Set中包含多个频带的 特例, 两者都需要增加可以检测 Serving Set内与 Serving Set外信号质量 的测量事件。
本发明实施例中, 通过测量服务小区当前 Serving set内与 Serving se t外的信号质量, 在服务小区当前 Serving Set信号质量下降时, 及时切换 S erving Set频带, 保证 UE数据高质量传输。
具体的, 包括:
A、 增加新的测量事件;
上述增加的测量事件包括:
测量事件 AX: 服务小区当前 Serving set内任一频带信号质量低于预先 设置的阈值, Serving set外频带信号质量比当前 Serving set内频带信号质 量还高一个偏置值。
该测量事件应用在当前服务集中频带信号质量变差时, 更换服务频带。 当 UE服务集中的任一频带信号质量变差, 网络侧根据该上报事件更换 UE服 务频带, 避免数据传输质量下降。
触发该事件后上报小区的频带集合可以是满足条件 Serving set 内信号 质量低于 Serving set外频带的频带; 或者可以根据频带的衰弱特性, 仅上 报满足条件的 Serving set外最高频点。 根据频带的衰弱特性, 可以近似的 认为 Serving set 内高于该频点的频点信号质量低于 Serving set外某些频 带, Serving set外低于该频点的信号质量都满足该事件。 测量事件 AY: Serving set 外频带比服务集内信号质量最好频带低一个 偏置值。
该事件为网络侧更换服务频带作准备。 当服务小区外某些频带信号质量 变强, 网络侧根据该测量事件上报, 及时切换频带, 获得更好的服务质量。 触发该事件上报小区集合包括: 满足条件 Serving set 外频带与 Serving se t 内全部频带信号质量。
对于新增力口的测量事件 Ax、 Ay, ¾ ReportConf igEUTRA information el ement中增加相关的事件 ID与相关阈值。

B、 修改邻区测量事件;
将服务小区内当前 Serving set外频带看作相邻小区的频带, Serving s et 内频带看做服务小区的全部频带, 服务集外的频带看做相邻小区的频带, 将相邻小区均看作非聚合小区, 根据相邻小区相关测量事件 A3 A4 A5测量结 果上报, 但此时的测量相关阈值, A3事件中的 offset , A4中的绝对阈值, A 5中的绝对阈值 1和绝对阈值 2根据服务小区各频带之间衰弱情况,更换频带 信号质量性能要求等因素确定, 可能会与相邻小区上报相关阈值不同。
歩骤 s202, 配置服务小区及相邻小区频带质量测量事件。
上述频带质量的测量包括 EUTRA***频带测量和异***频带测量。
对于 EUTRA***频带测量, 包括对现有技术中测量事件的修改。 其中, 对于服务小区质量上报的测量事件进行修改包括对下述事件的修改:
A1事件: 修改为服务小区全部频带或不需要 Gap测量频带信号质量高于 阈值; UE上报该事件表示当前服务小区信号质量很好, 不需要测量相邻小区 信号质量, 网络侧根据该事件可以选择关闭测量 Gap。
A2事件: 修改为服务小区某些频带或不需要 Gap测量频带信号质量低于 阈值; UE上报该事件表示当前 UE服务小区信号某些频带质量较差, 网络侧根 据该事件,可以不为该 UE在信号质量较差的频带上调度数据或考虑进行切换。
对于相邻小区测量事件的修改基于两种不同的假设:
假设 1 : UE不清楚相邻小区聚合情况, 将相邻小区均看作非聚合小区; 即聚合相邻小区看作不相关的几个单频小区处理。
这种情况下,对于 A3事件:相邻小区信号质量比服务小区高一个偏置值, 以及 A5事件: 服务小区信号质量低于绝对阈值 1, 并且相邻小区信号质量高 于绝对阈值 2 ; 如果此时服务小区为聚合小区, 相邻小区与聚合的服务小区进 行比较的频带可以有以下选择:
A、 Serving set中的最好频率; B、 服务小区全部频带中的最好频带。 这 两种上报的优点是减少了不必要的上报, 即如果当前服务小区内具有信号质 量很好的频带, 则可以使用该频带进行信号传输, 无需进行小区切换。 但是, 如果当前服务小区刚好有一个频段信号质量很好, 其他频段信号质量较差, 而该 UE使用高速业务, 需要多个频段服务, 则需要进行小区切换。 此时 A3 事件不会被上报, 仅能通过 A4、 A5进行切换。
C、 Serving set 中的最差频率, 这种上报的优点是上报邻区信号质量更 充分, 但同时, 如果网络侧通过服务小区上报相关事件, 更换频带而不切换 小区, 这种邻区上报结果会无用。
D、 Serving set中的加权平均信号质量, 这种方式是前两种方式的折中。 假设 2: UE了解相邻小区聚合情况;
当服务小区不是聚合小区, 而测量的相邻小区为聚合小区时, 需要判断 利用相邻小区哪个信号质量与服务小区进行比较, 可以有两种选择: A、 相令 小区信号质量最好频带; B、 相邻小区可用频带信号质量均值或加权均值。
当服务小区和相邻小区均为聚合小区时, 对于 A3和 A5可以采用如下 方式: A、 相邻小区信号质量最好频带和服务小区 Serving set中的最好频 或服务小区全部频带中的最好频带进行比较; B、两者的加权平均值进行比较 在配置的相关测量事件中需要增加相关指示采用哪种处理方法。 不同 测量事件可以采用相同的比较方式, 也可以不同。
采用原相邻小区测量事件 A3、 A4以及 A5之中的一个或多个来上报服 小区中服务集外频带信号质量的变化, 对于同一测量事件, 相邻小区与服 集外频带上报采用的阈值可以不同:
