Description

测量识别符的更新方法、 装置和系统 技术领域
本发明涉及通信领域， 特别涉及一种测量识别符的更新方法、 装置和系统。 背景技术
在 LTE-A ( Long Term Evolution- Advanced , 增强的长期演进） CA ( Carrier Aggregation, 载波聚合） 系统中， 多个载波聚合在一起， 可以同时与单个终端 （UE， User Equipment, 也称为用户设备或终端设备， 简称为终端） 进行通信， 也就是说， 一个终端具有多个服务小区。 在这多个服务小区中， 一个为主小区 （PCell: Primary Cell), 其它为辅小区 （SCell: Secondary Cell)。 在现有的 CA系统中， 聚合的小区都 在同一个基站下， 属于同基站的载波聚合系统。
在现有的 CA系统中， 基站需要给对终端进行测量配置， 包括下述参数： 测量目标：指的是终端需要执行测量的目标集。对于 E-UTRA (Evolved Universal Terrestrial Radio Access, 演进的通用陆地无线接入） 系统的同频或异频测量来讲， 一 个测量目标就是一个 E-UTRA载频； E-UTRAN (Evolved Universal Terrestrial Radio Access Network, 演进的通用陆地无线接入网） 能够配置与这个载频相关联的一个特 定于小区的偏置值列表和一个小区 "黑名单"列表， "黑名单" 中的小区在事件评估 和测量报告时都不予考虑。 对于跨 AT (Radio Access Technology, 无线接入技术） 的 UTRA (Universal Terrestrial Radio Access, 通用陆地无线接入）测量来讲， 一个测 量目标是单个 UT A载频上的一组小区。对于跨 AT的 GE AN (GSM EDGE Radio Access Network, GSM (Global System for Mobile Communications, 全球禾多动通信系 统） EDGE (Enhanced Data Rate for GSM Evolution, GSM增强数据率演进） 无线接 入网络）测量来讲，一个测量目标是 GE AN的一组载频。对于跨 AT的 CDMA2000 (Code Division Multiple Access, 码分多址） 测量来讲， 一个测量目标是单个 HRPD ( CDMA2000 High Rate Packet Data, CDMA2000 高速率分组数据） 或 lxRTT (CDMA2000 lx Radio Transmission Technology, CDMA2000 1倍无线传输技术） 载 频上的一组小区。
报告配置： 报告配置列表中的每个报告配置由报告准则和报告格式组成。报告准 则是用于触发终端发送测量报告的准则， 该准则可以是周期性的或单个事件描述。报 告格式指的是终端在测量报告中包括的数值和相关联信息，比如，报告的小区数量等。
测量识别符：测量识别符列表中的每个测量识别符将一个测量目标和一个报告配 置关联在一起。通过配置多个测量识别符，有可能将多个测量目标与同一个报告配置 给链接起来， 当然也有可能将多个报告配置与同一个测量目标链接起来。测量识别符 在测量报告中被用作参考数字。
数值配置： 每种 AT类型配置一个数值配置。 数值配置定义了测量数值和用于 此种测量类型的所有事件评估和相关报告的关联过滤器。过滤器能够被配置成特定于 每个测量数值。
测量间隙： 终端可以用于执行测量， 即没有上下行传输被调度的时段。
E-UTRAN对一个给定频率只配置一个测量目标， 即不可能对有不同相关参数的 同一个频率配置两个多个或多个测量目标， 比如， 有不同偏置值和 /或黑名单的频率。 E-UT AN可以配置同一个事件的多个实例， 比如， 配置两个具有不同阈值的报告配 置。
另外，报告准则中的用于触发测量报告的只涉及本系统的测量事件进一步包括以 下六种：
事件 A1 : 服务小区好于某个阈值。
事件 A2: 服务小区差于某个阈值。
事件 A3: 相邻小区好于 PCell与某个阶值的和。 其中， 相邻小区所在频率可以 与 PCell所在的频率不同。 相邻小区可以是服务小区。
事件 A4: 相邻小区好于某个阈值。
事件 A5: PCell差于某个阈值同时相邻小区好于另一个阈值。其中， 相邻小区所 在频率可以与 PCell所在的频率不同。 相邻小区可以是服务小区。
事件 A6: 相邻小区好于 SCell与某个阶值的和。 其中， 相邻小区是与 SCell在同 一个频率上。
在终端侧，为了记录测量相关的配置和过程，会存储与测量相关的两个变量，即： 测量配置变量和测量报告列表变量。
测量配置变量：终端在其中存储需要执行的测量的累积配置，这些测量包括同频、 异频和跨 RAT移动相关的测量。 这样， 每次基站通过空口对终端进行测量配置或者 终端执行与测量相关的过程时， 终端都有可能修改其存储的测量配置变量。测量配置 变量的具体内容包括一个测量识别符列表、 一个测量目标列表、 一个报告配置列表、 数值配置、 s-measure和速度状态参数。
测量报告列表变量： 终端在其中存储已经满足触发条件的测量的相关信息，包括 一个已经触发了报告的测量的列表。列表中每个触发报告的测量又进一步包括对应的 测量识别符、 一个已经触发报告的小区列表和已发送报告的数目。
终端在接收基站的测量配置、执行测量、报告测量结果以及执行与测量相关的过 程时， 有可能会对测量配置变量和测量报告列表变量进行修改。 比如， 终端侧对测量 识别符的移除操作。在现有的 CA系统中， 终端侧的测量识别符自动移除仅应用到现 有测量事件中的 Al、 A2禾 Π Α6。
另一方面， 在目前的 LTE-A系统中， 主要部署了宏小区。 未来随着业务量的增 力口， 可能要继续部署小小区。 小小区的覆盖面积比较小， 但是数量比较多。 所以， 如 果只是简单进行小小区的部署，不进行控制和结构优化，就会造成移动的健壮性降低， 控制信令负担增加等很多方面的问题。为了解决这些问题，同时为了提高单用户流量， 业界就提出了一种新型网络协议结构： 双连接。在双连接结构下， 终端可以同时与多 个基站同时进行通信。 比如， 终端可以同时与一个宏基站和一个小小区基站， 或者同 时与两个小小区基站进行通信。在与终端同时进行通信的基站中，有一个基站会给终 端提供终端与核心网之间的控制接口， 这个基站被称为为主基站。 除主基站之外， 其 它的与终端同时通信进行的基站称之为辅基站。 同时， 在终端的服务小区中， 关联于 主基站的小区组称之为主小区组， 关联于辅基站的小区组称之为辅小区组。
应该注意， 上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、 完整的说明， 并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发 明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。 发明内容
在双连接结构下， 终端的服务小区分布在两个小区组中： 主小区组中有主小区， 并且可能会有辅小区； 辅小区组中至少一个辅小区， 并且辅小区组中至少有一个辅小 区会承载该终端的 PUCCH (Physical Uplink Control Channel, 物理上行控制信道）， 为了方便说明， 将辅小区组中承载 PUCCH的辅小区称为该终端的 "主辅小区"。 在双连接结构下， 系统会定义一些新的测量事件， 在这个新的测量事件中， 可能 对关联的测量目标有一定的要求， 比如要求测量目标是辅小区组中小区所在频率， 或 者新的测量事件中， 要求测量目标的测量结果与特定小区的测量结果进行比较， 比如 主辅小区。如果终端发生了连接重配或连接重建过程，可能与测量事件相关联的测量 目标不再满足该测量事件的要求， 或者与测量目标对比测量结果的小区（为了方便说 明， 简称为对比小区）不复存在， 此时， 如果按照现有协议， 终端只能自动移除走与 Al、 A2和 A6关联的测量识别符， 不能移除走与新的测量事件相关联的测量识别符， 终端就会继续进行无谓的测量， 浪费了终端能量， 影响了正常通信。
本发明实施例提供一种测量识别符的更新方法、装置和系统， 以解决在双连接结 构下，终端无法及时移除与新的测量事件相关的测量识别符而引发的无谓的测量的问 题。

实施例 1
本发明实施例提供了一种测量识别符的更新方法，该方法可以应用于双连接结构 下的终端设备， 但本实施例并不以此作为限制。 为了方便说明， 下面以该方法应用于 双连接结构下的终端设备为例进行说明。 图 1是该方法的流程图， 请参照图 1， 该方 法包括：
步骤 101 : 终端设备在执行了连接重配或者连接重建后， 检查包含在预存的测量 配置变量中测量识别符列表中的每个测量识别符；
在本实施例中， 如前所述，每个终端都保存有一个测量配置变量和一个测量报告 列表变量， 在测量配置变量中， 包含有一个测量识别符列表， 该测量识别符列表指示 了需要执行测量的每个测量识别符， 如前所述，每个测量识别符关联了一个测量目标 和一个报告配置。
步骤 102: 如果所述测量识别符所关联的报告配置包含与所述终端设备的辅小区 组中小区所在的频率相关的测量事件，并且与所述测量事件相关的测量目标不再满足 所述测量事件的要求或者所述测量事件中的对比小区不再存在，则所述终端设备将所 述测量识别符从所述测量配置变量中移除。
在本实施例中，基站有可能为终端配置新的测量事件， 并且该新的测量事件与该 终端的辅小区组中的小区所在的频率相关， 则， 如果该终端的测量配置变量的测量识 别符列表中的测量识别符所关联的报告配置包含有该新的测量事件，并且与该新的测 量事件相关的测量目标在经过该终端的连接重配或连接重建之后不再满足该测量事 件的要求或者该测量事件中的对比小区不再存在，则该终端可以将该测量识别符从其 测量配置变量中移除， 以防止终端继续进行该测量标识符所对应的测量， 由此可以减 少不必要功耗和对正常通信的影响。
在本实施例的一个实施方式中，如果该终端的测量报告列表变量中包括该测量识 别符对应的测量报告记录， 也即该终端已经执行过针对该测量识别符的测量和上报， 则该终端还可以将该测量识别符对应的测量报告记录从该测量报告列表变量中移除。
在本实施例的一个实施方式中， 如果与该测量识别符对应的计时器正在运行， 则 该终端还可以停止正在运行的与该测量识别符对应的计时器，并重置与该测量识别符 相关的信息。这里的计时器可以是周期报告计时器， 本实施例并不以此作为限制。这 里， 与该测量识别符的信息可以是 TTT (Time to Trigger, 触发时间）， 但本实施例并 不以此作为限制。
在本实施例中， 该新的测量事件可以是：相邻小区的测量结果好于主辅小区的测 量结果与预定阶值的和； 或， 相邻小区的测量结果好于第一阈值， 同时主辅小区的测 量结果差于第二阈值； 或， 小区的测量结果好于第三阈值； 或， 小区的测量结果差于 第四阈值。但本实施例并不以此作为限制，其它的与双连接结构下的终端的辅小区组 中的小区所在的频率相关联的测量事件都可以作为本实施例的该新的测量事件。
在本实施例中，触发该新的测量事件的小区位于该测量识别符所关联的测量目标 所指示的频率上。其中， 该测量目标所指示的频率可以是该终端的辅小区组或辅基站 中小区所在的、除主辅小区所在的频率之外的频率； 也可以是该终端的辅小区组或辅 基站中的小区所在的频率； 也可以是该终端的主小区组或主基站中小区所在的频率； 也可以是不同于主小区所在频率的频率； 也可以是不同于主辅小区所在频率的频率； 也可以是不同于主小区和主辅小区所在频率的频率，等等，本实施例并不以此作为限 制。 在本实施例中，能够触发终端进行自动移除测量识别符的操作包括连接重配和连 接重建过程， 其中连接重配包括切换和非切换两种情况。 对于双连接结构下的终端， 其在执行了连接重配或连接重建后，可以自动执行本实施例提出的该移除测量识别符 的操作。 其中， 在执行了连接重配后， 该终端的主小区没有发生改变， 但是辅基站发 生了改变； 或， 该终端的主小区没有发生改变， 辅基站没有发生改变， 但是主辅小区 发生了改变； 或， 该终端的主小区和主辅小区都没有发生改变， 但是普通辅小区发生 了改变， 也即主小区组中的辅小区和 /或辅小区组中除去主辅小区的辅小区发生了变 化； 或， 该终端的主小区没有发生改变， 但是该双连接结构不再存在， 也即只与一个 基站进行通信； 或， 该终端的主小区发生了变化， 也即该终端执行了切换， 在这种情 况下， 该终端的辅小区组中的小区可能发生变化， 也可能不发生变化， 也可能双连接 结构不再存在。 其中， 在执行了连接重建后， 该终端只有主小区一个服务小区。
下面通过举例对本实施例的方法进行说明。
在现有的 CA系统中， 如前所述， 终端侧的测量识别符的自动移除仅应用到现有 测量事件中的 Al、 A2禾 Π Α6。 假设终端有三个服务小区： 频率为 F1的主小区 Celll、 频率为 F2的辅小区 Cell2和频率为 F3的辅小区 Cell3， 如图 2所示。 同时终端配置 了三个测量识别符： Measldl、 Measld2和 Measld3， 这三个测量识别符都保存在终端 的测量配置变量中。 其中， 与 Measldl 关联的测量目标是 Fl， 测量事件是 A2; 与 Measld2关联的测量目标是 F2， 测量事件是 A1 ; 与 Measld3关联的测量目标是 F3， 测量事件是 A6。
如果终端发生了链路失败并进行了连接重建， 并且该终端在 F1上的 Cell4中重 建连接成功。 此时， 终端只有一个服务小区， 也即 F1上的 Cell4。 这个时候， 终端发 现与 Measld2关联的测量目标是 F2，而与 Measld2关联的测量事件 A1要求测量的小 区是服务小区， 由于此时终端在 F2上已经没有配置的服务小区了， 终端就要从测量 配置变量中的测量识别符列表中移除掉 Measld2对应的记录。当然， 如果在测量报告 列表变量中也有 Measld2对应的测量报告记录， 也应该删除掉。 对应于 Measld2， 如 果周期报告计时器在运行， 也要停止掉， 同时还要重置相关的信息， 比如： TTT计时 器。 同理， 对 Measld3， 也要采取与 Measld2相似的自动移除。
如果终端发生了连接重配， 例如切换， 切换之后， F1上的 Cell4成为终端的主小 区， F2上的 Cell5 成为终端的辅小区， 如图 2所示。 这个时候， 终端发现与 Measld3 关联的测量目标是 F3，而与 Measld3关联的测量事件 A6要求测量目标是辅小区所在 的频率， 由于此时终端在 F3上已经没有配置的服务小区了， 终端就要从测量配置变 量中的测量识别符列表中移除掉 Measld3对应的记录。当然， 如果在测量报告列表变 量中也有 Measld3对应的测量报告记录， 也应该删除掉。 对应于 Measld3， 如果周期 报告计时器在运行， 也要停止掉， 同时还要重置相关的信息， 比如： TTT计时器。
在双连接的结构下，终端侧的测量识别符的自动移除可以应用到前述新的测量事 件。下面通过两个例子对双连接结构下的终端在连接重配或连接重建后自动移除测量 识别符的过程进行说明。
图 3a是由于测量识别符所关联的测量目标不再满足该测量识别符关联的测量事 件对测量目标的要求， 而导致终端进行测量识别符的自动移除的一个示例。 如图 3a 所示， 假设终端有三个服务小区： 频率为 F1 的主小区 Celll属于主小区组、 频率为 F2的主辅小区 Cell2和频率为 F3的辅小区 CelB属于辅小区组， 同时终端配置了三 个测量识别符： Measldl、 Measld2和 Measld3， 这三个测量识别符都保存在终端的测 量配置变量中。其中，与 Measldl关联的测量目标是 Fl，测量事件是 A2; 与 Measld2 关联的测量目标是 F2， 测量事件是 A1 ; 与 Measld3关联的测量目标是 F3， 测量事件 是新的测量事件， 暂简称为 A7， 例如： 相邻小区的测量结果好于主辅小区的测量结 果与预定阶值的和。 这里， A7中相邻小区所在的频率要求是包含在终端的辅小区组 中小区所在频率中同时不同于主辅小区所在的频率。如果终端发生了移动，双连接发 生了改变， 例如： 主小区组没有发生改变， 辅基站发生了改变。 此时， 辅小区组中只 有一个小区， 即： 在频率 F2上的主辅小区 Cell4。 由于 Measld3对应的 A7事件要求 测量目标对应的频率需要包含在辅小区组中小区所在频率中但不同于 F2， 但此时辅 小区组中只有 F2， 那么终端就要从测量配置变量中的测量识别符列表中移除掉 Measld3对应的记录。 当然， 如果在测量报告列表变量中也有 Measld3对应的测量报 告记录， 也应该删除掉。对应于 Measld3， 如果周期报告计时器在运行， 也要停止掉， 同时还要重置相关的信息， 比如： TTT计时器。
图 3b是由于测量识别符所关联的测量事件的定义不再被满足而导致终端进行测 量识别符的自动移除的一个示例。 如图 3b所示， 假设终端有三个服务小区： 频率为 F1的主小区 Celll属于主小区组、频率为 F2的主辅小区 Cell2和频率为 F3的辅小区 CelB属于辅小区组，同时终端配置了三个测量识别符： Measldl、MeasId2和 Measld3， 这三个测量识别符都保存在终端的测量配置变量中。其中， 与 Measldl关联的测量目 标是 Fl， 测量事件是 A2; 与 Measld2关联的测量目标是 F2， 测量事件是新的事件， 暂简称为 A8， 例如： 相邻小区的测量结果好于主辅小区的测量结果与预定阶值的和。 A8中相邻小区要求是不同于主辅小区所在频率上的小区。 与 Measld3关联的测量目 标是 F3， 测量事件是新的测量事件， 暂称为 A9， 例如： 相邻小区的测量结果好于第 一阈值， 同时主辅小区的测量结果差于第二阈值。 这里， A9中相邻小区要求是不同 于主辅小区所在频率上的小区。 如果终端发生移动， 主小区组没有发生改变， 但是辅 基站被释放。 这个时候， 终端已经没有主辅小区的配置， 而 A8和 A9事件要求相邻 小区的测量结果需要与主辅小区的测量结果比较， 因此， 终端就要从测量配置变量中 的测量识别符列表中移除掉 Measld2和 Measld3对应的记录。当然， 如果在测量报告 列表变量中也有 Measld2和 Measld3对应的测量报告记录， 也应该删除掉。 对应于 Measld2和 Measld3， 如果周期报告计时器在运行， 也要停止掉， 同时还要重置相关 的信息， 比如： TTT计时器。
