本发明涉及通信技术领域， 具体涉及一种多载频系统中的小区测量方法、 装置以及系统。
背景技术
在当今无线通信给人们的生活带来了更多的方便和更多新的体验的同时， 如何使得无线通信更加可靠、 高速是人们不断研究的方向。 其中， 高速分组接 入（ HSPA， High Speed Packet Access )技术是现阶段研究出的一项技术， 在该 技术的基础上，还扩展出了高速上行链路分组接入（ HSUPA, High Speed Uplink Packet Access )技术和高速下行链路分组接入（ HSDPA, High Speed Downlink Packet Access )技术， 实现了一个移动终端可以同时和多个多载波小区建立多 载波连接， 进一步提高移动终端与网络侧的数据传输速率。 还需要说明的是， 采用 HSDPA和 HSUPA技术进行多小区数据传输的系统可以称为多小区高速 分组接入 （ MC-HSPA , Multi Cell HSPA ) 系统或多载频高速分组接入 (MC-HSPA, Multi Carrier HSPA)系统。

由以上说明可知， 现有技术中网络侧对终端的小区切换， 使得切换后的终 端与网络侧的通信质量不能保证， 不利于用户体验。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是 全部的实施例。基于本发明中的实施例， 本领域普通技术人员在没有做出创造 性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
本发明实施例提供一种多载频系统中的小区测量方法，本发明实施例还提 供相应的装置以及通信系统。 以下分别进行详细说明。 实施例一
本发明实施例提供了一种多载频系统中的小区测量的方法，参见图 1所示， 该方法包括：
步骤 1 : 接收网络侧发送的测量控制消息， 该测量控制消息中至少包括： 终端当前主载频邻区的小区信息、辅载频邻区的小区信息、 主载频邻区和辅载 频邻区之间的协作关系、 小区测量量和测量上报条件；
其中， 步骤 1中测量控制消息通常是由网络侧的无线网络控制器发送的， 网络侧在发送给终端该测量控制消息之前， 知道终端当前工作的 MC-HSPA系 统以及该 MC-HSPA系统中的各个小区。 而且， 网络侧知道与该 MC-HSPA系统 相邻的 MC-HSPA系统或者单载频小区的情况。 测量控制消息中的主载频邻区 和辅载频邻区之间的协作关系， 就是用来说明相邻的 MC-HSPA系统的组成。
需要说明的是， 组成 MC-HSPA系统的多个小区称为多载频小区， 在
MC-HSPA系统中， 网络可以定义终端的主载频和辅载频， 主载频只有一个， 辅载频可以有一个或多个，终端当前工作的主载频小区称为终端当前的主载频 服务小区， 在 MC-HSPA系统的其他小区， 称为该终端当前的辅载频服务小区。 为了便于理解， 参见图 2所示的小区分布图， 其中， Cll、 C12和 C13三个小区 的载频相同， C21、 C22、 C23和 C24四个小区的载频相同， C31、 C32、 和 C33 三个小区的载频相同， 该小区分布图中除了小区 C24是单载频小区外， 其余都 是多载频小区。假设此时终端可以同时在小区 C12、 C22和 C32进行 HSPA操作， 组成一个 MC-HSPA系统，那么， C22是终端当前工作的主载频小区， C12和 C32 是终端当前的辅载频小区，则 C21、 C23和 C24是终端的主载频邻区， Cll、 C13、 C31和 C33是终端的辅载频邻区。 网络侧知道与当前 MC-HSPA系统相邻的 MC-HSPA系统包括： Cll、 C21和 C31组成的 MC-HSPA系统， 和 C13、 C23和 C33组成的 MC-HSPA系统。在本发明以下的各实施例中， 主载频邻区包括终端 当前工作的小区和终端当前在主载频上的邻小区，辅载频邻区包含终端当前的 辅载频小区和终端当前在辅载频上的邻小区， 即在本发明实施例中将 C22认为 是终端的主载频邻区， 将 C12和 C32认为是终端的辅载频邻区， 且 C22与 C12和 C32有协作关系，三个小区协作组成 MC-HSPA系统，满足终端当前的通信要求。
其中， 步骤 1中对主载频邻区和辅载频邻区所进行的小区测量量， 是指网 絡侧配置给终端的测量控制消息中， 指示需要对小区测量的测量参数， 可以包 含下述一种或几种： 路径损耗 (Pathloss)、 接收信号码功率 (CPICH RSCP)、 信 号干扰比 (CPICH Ec/N0)。 终端根据这些参数对小区进行测量。 下面描述中的 小区测量量的解释都可以按照上述描述来理解。 小区测量量和测量上报条件， 可以是相同的， 也可以不同的， 可以根据设计者的要求而决定。 小区测量量和 测量上报条件被称为测量指示。
步骤 2: 根据接收到的测量控制消息的小区测量量， 对主载频邻区和辅载 频邻区进行测量；
步骤 3: 根据步骤 1中接收到的测量控制消息中的测量上报条件， 判断每个 邻区的测量结果是否满足测量上 · ^条件， 即判断步骤 2中测量出的主载频邻区 和辅载频邻区的测量结果是否满足上报条件， 如果是， 进入步骤 4;
步骤 4:根据步骤 1中接收到的测量控制消息中的主载频邻区和辅载频邻区 之间的协作关系， 发送测量"^告给网络侧。
其中， 步骤 4中的发送的测量报告中至少包括： 满足上报判断标准的测量 的主载频邻区的小区信息和测量结果，和与主载频邻区有协作关系的所有辅载 频邻区的小区信息和测量结果； 或者该测量报告中至少包括： 满足上报判断标 准的测量的辅载频邻区的小区信息和测量结果，以及与该辅载频邻区有协作关 系的主载频邻区和辅载频邻区的小区信息和测量结果。
通过以上对本发明实施例提供的一种多载频系统中的小区测量方法的说 明， 可知终端根据网络侧发送的测量控制消息，对该终端的主载频邻区和辅载 频邻区进行测量， 根据测量控制消息中的测量上报条件， 判断是否发送测量报 告给网络侧， 如果是， 根据主载频邻区和辅载频邻区之间的协作关系， 发送测 量报告给网络侧。使得网络侧可以根据主载频邻区和与之协作的辅载频邻区的 测量结果， 进行综合的判断， 保证了终端切换到其他的小区后的通信质量， 终 端切换到的小区为主载频邻区和与该主载频邻区协作的辅载频邻区组成的 MC-HSPA系统。 实施例二
本发明实施例提供了一种多载频系统中的小区测量方法。下面结合附图对 本实施例进行说明。
仍然以图 2为例进行说明， 即终端当前工作在 C12、 C22和 C32这三个小区， C22小区是终端的主载频小区， 同时也是主载频邻区， C12和 C32两个小区认为 是终端的辅载频小区，同时也是辅载频邻区。网络侧知道终端当前工作在 HSPA 状态下的所有邻区的是如图 2中所示的所有小区， 且网络侧知道： 前三列小区 分别组成了三个 MC-HSPA系统（即小区 Cll、 C21和 C31组成一个 MC-HSPA系 统、 小区 C12 、 C22和 C32组成一个 MC-HSPA系统、 小区 C13 、 C23和 C33组 成一个 MC-HSPA系统）， C24是一个单载频小区。 下面结合图 2所示的终端当前 工作的网絡环境， 对本发明实施例二提供的方法做说明。
参见图 3所示， 该方法包括：
步骤 A1 : 终端接收网络侧的无线网络控制器发送的测量控制消息， 该测 量控制消息包括： 邻区列表和测量控制指示；
其中， 邻区列表中包括终端当前主载频邻区的小区信息、辅载频邻区的小 区信息、主载频邻区和辅载频邻区的协作关系。如表 1所示为针对图 2中所示的 网络环境的邻区列表的具体形式。
同频邻区
主载频邻区 C21 (分别存放 C11和 C31的位置索引）， C22 (分别存 放 C12和 C32的位置索引）， C23 (分别存放 C13和 C33 的位置索引）, C24 辅载频邻区 C11, C12, C13, C31, C32, C33
Figure imgf000009_0001
援引实施例一中的例子， C22是终端当前工作的主载频小区， C12和 C32 是终端当前的辅载频小区，则 C21、 C23和 C24是终端的主载频邻区， Cll、 C13、 C31和 C33是终端的辅载频邻区。 上述邻区列表中的同频邻区是指： 与终端当 前工作的 MC-HSPA系统中的所有载频相同的小区， 且包括终端当前工作的 MC-HSPA系统中的小区， 即图 2中所示的所有小区。 在表 1中的同频邻区包括 了主载频邻区和辅载频邻区， 其中， 在主载频邻区一项中显示出了主载频邻区 的小区信息， 在 "（ )"里面的内容表示与该主载频邻区协作的辅载频邻区的位 置索引； 在辅载频邻区一项中显示出了辅载频邻区的小区信息。 同频邻区中放 的是与终端当前工作的 MC-HSPA系统中的所有载频相同的小区的小区信息， 每个小区都对应一个位置索引， 这个位置索引可以是隐藏表示的。 关于小区信 息的理解可以参考现有技术。
为了便于理解， 以上是采用 "（ ）" 的形式对邻区列表中协作关系做描述。 在实际操作的过程中， 网络侧发送终端的有关协作关系的指示也可以是位图 (Bitmap)的形式。 具体是将所有同频邻区用二进制指示， 比如终端当前同频邻 区列表中一个配置有 6个邻区，那么就可以用 000000分别表示同频邻区 1到同频 邻区 6。 如果同频邻区 1是主载频邻区， 与它进行协作的辅载频邻区是同频邻区 3和同频邻区 4 , 那么对于协作关系指示可以表示为 001100。
还需要说明的是， 步骤 A1中发送的测量控制指示中包括： 小区测量量（测 量的参数） 和测量上报条件。 为了便于让终端进行测量， 步骤 A1中发送的测 量控制指示可以根据邻区列表的形式决定如何测量各小区，网络侧可以对终端 进行主载频邻区和辅载频邻区配置相同的测量控制指示，即网络侧通知终端对 主载频邻区中的各小区进行同频测量，对辅载频邻区中的各小区采用与主载频 邻区相同的测量控制指示。在本实施例中， 以终端对主载频小区和辅载频小区 采用相同的测量控制指示为例进行说明。也可以有其它的测量控制指示， 在本 实施例中的后面的文字中会说明。
步骤 A2： 终端根据接收到的测量控制消息中， 对邻区列表中的同频邻区 进行测量；
其中 , 步骤 A2中终端对邻区列表中的同频邻区进行测量， 即对邻区列表 中的所有小区都进行的测量，根据测量控制消息中的测量控制指示，对各小区 的测量可以分主载频邻区和辅载频邻区两类测量， 也可以不加以区分。 终端对 主载频邻区的测量进行同频测量， 即在每个主载频邻区进行路径损耗 (Pathloss). 接收信号码功率 (CPICH RSCP)、 和 /或信号干扰比 (CPICH Ec/N0) 等测量。 终端对每个辅载频邻区的测量可以与主载频邻区相同， 也可以称为对 辅载频邻区进行同频测量。
步骤 A3 : 终端根据接收到的测量控制消息， 判断测量出各邻区的测量是 否满足测量上报条件， 如果是， 进入步骤 A4;
其中， 步骤 A3中需要上报的判断标准可以是网络侧根据预设的规则、 或 人工控制而设计出的。 例如当对小区的测量结果为某个范围时， 需要通知网络 侧。
步骤 A4: 终端根据接收到的测量控制消息中的邻区列表中的主载频邻区 和辅载频邻区的协作关系， 发送测量报告给网络侧。
其中， 为了便于理解， 假设步骤 A3中判断出： 在如图 2中所示的网络环境 中， 测量出满足上报标准的小区有 C24、 〇21和( 13， 在步骤 A4中终端根据邻 区列表中中小区间的协作关系， 即： 小区 C24是一个单载频小区； 小区 C21与 小区 C11和 C31有协作关系 （即 C21、 Cl l、 C31构成了一个 MC-HSPA系统）； 小区 C13与小区 C23和 C33具有协作关系（即 C13、 C23和 C33构成一个 MC-HSPA 系统）。 终端根据获取的协作关系， 发送测量报告， 在该测量报告中包括满足 上报标准的主载频邻区、 与该主载频邻区有协作关系的小区， 以及满足上报标 准的辅载频邻区的测量结果， 即包括小区 C24的测量结果、 小区 C21的测量结 果、 与小区 C21协作的小区 C11和 C31的测量结果， 以及小区 C13的测量结果。 该测量包括中还可以包括与满足上报标准的辅载频邻区有协作关系的主载频 和 /或辅载频小区， 即与 C13协作的小区 C23和 /或 C33的测量结果。 通过以上对步骤 Al至步骤 A4的说明 , 实现了一种多载频系统中的小区测 量的方法， 需要说明的是， 在步骤 A1中终端接收到网络侧发送的测量控制消 息中的邻区列表的形式可以是不同的， 下面仍然根据图 2中所示的网络环境 , 介绍几种邻区列表的格式， 并且会针对各个邻区列表， 说明具体的测量控制指 示与步骤 A1中说明的测量控制指示的不同。
如表 2所示， 在该邻区列表中， 针对图 2中所示的十个小区， 将与终端当前 工作的 MC-HSPA系统中任意一种载频相同的小区都认为是终端的同频小区， 且将载频相同的小区分类， 分为三个同频邻区， 例如： 小区 Cll、 C12和 C13 三个小区的载频相同， 被划分为同频邻区 2中的小区。 在该邻区列表中， 在主 载频邻区一项中表示出了主载频邻区和辅载频邻区之间的协作关系。且在实际 应用中， 具体表示协作关系的形式可以是 Bitmap形式， 全文都应该遵循这样的 理解。 同频邻区 1

辅载频邻区 同频邻区 3 辅载频邻区 C31, C32, C33
Figure imgf000012_0001
根据该表 2所示的邻区列表， 对于终端对各同频邻区区别对待的情况， 在 辅载频数量大于等于 2个的情况下， 网络侧还需要对每组同频邻区进行区分 , 具体的可以通过载频信息或者单独的标识进行区分不同的同频邻区。 同时， 在 网絡侧发送给终端的测量控制消息中， 可以根据指示同频邻区 1、 2、 3配置相 同或不同的测量控制指示。
本发明实施例中的邻区列表还可以是如表 3所示的形式，仍然是以图 2中所 示的网络环境为例， 对表 3进行说明。
表 3中将同频邻区划分为两类即： 主载频邻区和辅载频邻区， 参考上文中 的说明容易理解该表格， 该表不同与表 1和表 2在于， 在表 3中将邻区之间的协 作关系单独列出， 即在协作关系中将小区分组，每一组中包括具有协作关系所 有的小区， 且将每组中的每个小区的位置索引标识出。

采用表 3所示的邻区列表的情况下， 网络侧通知终端对同频邻区中所有小 区进行的测量控制指示是相同的。
本发明实施例中的邻区列表还可以是如表 4所示的形式，仍然是以图 2中所 示的网络环境为例， 对表 4进行说明。
表 4中将所有的同频邻区划分为组， 每个组中的所有小区就是一组具体协 作关系的系统，在每个组中又划分的更细致， 包括：主载频小区和辅载频小区， 且辅载频小区是主载频小区的下一级。
Figure imgf000013_0001
表 4
采用表 4所示的邻区列表， 可以通过上下级别的关系来突出主载频邻区和 辅载频邻区之间的协作关系。 网络侧发送给终端如表 4所示的邻区列表时， 终 端对个小区的测量， 可以根据邻区列表中显示的级别关系， 相同级别配置相同 的小区测量控制指示， 不同级别的小区配置不同的小区测量控制指示， 也可以 对所有小区不分级别采用相同的测量控制指示。
在本发明实施例中， 上述表 1、 表 2和表 4中主载频邻区和辅载频邻区都在 同频邻区中指示， 主载频邻区和辅载频邻区的测量指示可以不相同， 因此需要 对主载频邻区和辅载频邻区进行区分，例如可以在同频邻区中各个小区的小区 信息中增加载频信息、 或者单独的标识来进行区分。
为了便于理解本发明实施例提供的技术方案， 还需要说明的是， 终端接收 到的网络侧发送的测控控制消息中的邻区列表中的信息 ,是通知终端当前可以 切换的小区的情况。 网络侧根据小区的载频情况， 将小区分为终端的主载频邻 区和辅载频邻区两大类。在邻区列表中突出辅载频小区和辅载频邻区之间的协 作关系 , 综合考虑切换小区后， 组成的 MC-HSPA系统是否可以保证终端的通 信质量。 以上表 1至表 4所列出的邻区列表的形式， 其本质是相同的， 且表 1至 表 4所列出的邻区列表中辅载频邻区被归类为同频邻区的范围中。实际操作中 , 辅载频邻区也可以被归类为异频邻区， （其中， 关于异频邻区的定义可以参考 现有技术中的理解。）对辅载频邻区的测量控制指示可以是异频测量控制指示， 并且除了辅载频邻区外的异频邻区和辅载频邻区的测量控制指示可以相同，也 可以不同。
参见表 5所示的一种将辅载频邻区归类为异频邻区的邻区列表。

参见表 7所示的邻区列表， 容易理解的是， 该邻区列表中将辅载频邻区归 属为异频邻区， 且才艮据异频邻区的载频频率将异频邻区分组为： 异频邻区 1、 异频邻区 2和异频邻区 3。需要理解的是表 7所示为一种可行的邻区列表的形式， 还有其它将辅载频邻区归属为异频邻区的邻区列表形式，此处不应理解为对本 发明实施例提供的邻区列表形式的限制。不同形式的邻区列表可以根据设计要 求来设计， 来指导终端对各小区所进行的小区测量。
通过以上对本发明实施例提供的一种多载频系统中的小区测量方法的说 明， 终端根据网络侧发送的测量控制消息，对包括终端当前工作小区和邻区的 各小区进行测量， 根据测量控制指示判断是否发送测量报告给网络侧。 如果需 要发送测量报告给网络侧， 则根据主载频邻区和辅载频邻区之间的协作关系， 发送测量报告给网络侧。这样使得网络侧可以根据主载频邻区和与之协作的辅 载频邻区的测量结果进行综合的判断，保证了终端切换到其他的小区后的通信 质量，终端切换到的小区为主载频邻区和与该主载频邻区协作的辅载频邻区组 成的 MC-HSPA系统。 实施例三 本发明实施例提供一种移动通信终端， 如图 4所示， 该终端包括： 接收单 元 10、 测量单元 20、 判断单元 30和发送单元 40。
其中， 接收单元 10 , 用于接收网络侧发送的测量控制消息；

判断单元 30, 用于根据接收到的测量控制消息中的测量上报条件， 判断是 否将测量出的主载频邻区和 /或辅载频邻区的测量结果发送给网络侧， 如果是， 通知发送单元 40;
发送单元 40，用于当判断单元 30中判断结果是需要将测量结果发送给网络 侧时，根据接收到的测量控制消息中的主载频邻区和辅载频邻区之间的协作关 系， 发送测量报告给网络侧。
其中，接收单元 10中接收到的测量控制消息， 包括邻区列表和测量控制指 示。邻区列表中的具体形式可以参考表 1至表 4任一种形式，也可以有其他形式。 在邻区列表中至少包括： 主载频邻区的小区信息、 辅载频邻区的小区信息、 和 主载频邻区与辅载频邻区之间的协作关系。主载频邻区和辅载频邻区之间的协 作关系的指示可以是采用 Bitmap形式表示。
测量单元 20根据接收到的测量控制消息对各小区进行测量， 其中， 针对每 个小区的测量控制指示可以是相同的， 也可以是不同的。 可以根据主载频邻区 和辅载频邻区将小区分为两类进行测量，每类中的各小区釆用相同的测量控制 指示； 也可以根据协作关系进行分类， 对一组具有协作关系的小区釆用相同的 测量控制指示； 也可以根据载频信息进行分类， 将具有相同载频信息的小区分 为一组，对每组中的小区釆用相同的测量控制指示。 以上是举例出了三种可能 的测量方案， 但是不应该理解为对本发明实施例的限制， 还可以有其它测量策 略， 此处不做限定。
移动通信终端中的判断单元 30根据接收到的测量控制消息和测量单元 20 中获取的测量结果， 判断是否将测量结果发送给网络侧。 具体的判断方法可以 是， 以图 2中的网絡环境为例， 假设终端接收到的测量上报条件为： 当测量到 小区 C21的的路径损耗小于网路侧配置的测量触发条件的预设门限值时， 终端 需要上报主载频邻区和与该主载频邻区协作的辅载频邻区的测量结果，即终端 需要上艮小区 C21、 C11和 C31的测量结果。
移动通信终端中的发送单元 40, 根据判断单元 30中的判断结果， 将满足判 断标准的小区 C21的测量结果 （延续上面的假设情况）， 和与 C21协作的小区 Cll、 C31的测量结果一同发送给网络侧， 使得网络侧不单只知道要切换的某 个邻区的通信质量 , 还知道切换到的该邻区所在的 MC-HSPA系统的通信质量 从而保证了终端的通信顺畅， 可靠性。
通过以上对本发明实施例提供的一种终端的说明 ,该终端根据网络侧发送 的测量控制消息， 对包括移动终端终端当前工作小区和邻区的各小区进行测 量， 根据测量控制消息中的测量上报条件， 判断是否发送测量报告给网络侧， 如果是，根据主载频邻区和辅载频邻区之间的协作关系， 发送测量报告给网络 侧， 使得网络侧可以根据主载频邻区和与之协作的辅载频邻区的测量参数值 , 进行综合的判断， 保证了终端切换到其他的小区后的通信质量， 终端切换到的 小区为主载频邻区和与该主载频邻区协作的辅载频邻区组成的 MC-HSPA系 统。
