含小区 2的 EARFCN (f2， y) 和小区 2支持的频带 z， 其中支持的频带 z通过新增的 扩展信令指示， 支持对应信令版本的终端才能正确解析出新增的扩展信令。 小区 2的 系统消息广播中， 包含了小区 2支持的频带 和 ， 其中 y在扩展的信令中描述的。 终端在小区 1进入连接态， 由于终端不支持频带 y， 基站给终端配置测量任务， 测量 对象是小区 2的载频 EARFCN (f2， z),基站根据测量报告， 让终端切换到小区 2 (£2， z), 然后由于终端的业务释放， 需要进入 IDLE态， 但是终端不支持频带 y， 而且终端 是旧版本的终端， 无法解析新增的扩展信令， 即终端只能看到小区 2 (f2， y)， 因此终 端无法驻留到小区 2， 则终端只能选择其他小区比如小区 1进行驻留， 或者进入无小 区驻留状态。 针对上述问题， 目前还没有提出有效的解决方案。 发明内容 针对相关技术中在多频带小区的情况下终端切换后无法在目标小区驻留的问题， 本发明提供了一种多频带小区间切换的指示方法、装置及系统， 以至少解决上述问题。 根据本发明的一个方面， 提供了一种多频带小区间切换的指示方法， 包括： 基站 向连接态下的终端配置测量任务， 其中， 所述测量任务中的测量对象包括： 一个载频 以及该载频对应的物理频点归属的所有频带信息中除该载频对应的频带以外的其他频 带信息； 所述基站将所述测量任务配置给所述终端， 其中， 所述其他频带信息通过预 定的扩展信令指示； 所述基站接收所述终端根据所述测量任务执行测量后上报的测量 报告； 所述基站根据所述测量报告， 指示所述终端切换到小区。 优选地， 在所述基站将配置的所述测量任务下发给所述终端之后， 所述方法还包 括： 所述终端从所述基站配置的所述测量任务中获取测量对象中的所述载频， 如果所 述终端支持解析所述预定的扩展信令， 则获取所述预定的扩展信令指示的所述其他频 带信息对应的载频； 所述终端进行获取的所述载频上的小区进行测量； 在上报测量报 告时， 所述终端向所述基站上报测量报告， 其中， 所述测量报告包括： 所述终端测量 到的满足测量报告上报条件的各个小区的测量结果。 优选地， 在所述基站接收所述终端根据所述测量任务执行测量后上报的测量报告 之后， 所述方法还包括： 所述基站根据所述测量报告中包含的小区的测量结果， 判断 所述终端是否能够解析所述预定的扩展信令。 根据本发明的又一个方面， 提供了一种小区测量方法， 包括： 连接态下的终端接 收基站为所述终端配置的测量任务， 其中， 所述测量任务中配置的测量对象： 一个载 频以及该载频对应的物理频点归属的所有频带信息中除该载频对应的频带以外的其他

具体实施方式 下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是， 在不冲突的 情况下， 本申请中的实施例及实施例中的特征可以相互组合。 根据本发明实施例， 提供了一种多频带小区间的切换系统。 图 4为根据本发明实施例的多频带小区间的切换系统的结构示意图，如图 4所示， 该系统主要包括： 基站 2和连接态下的终端 4。 在本发明实施例中， 可以在基站 2中设置一个多频带小区间切换的指示装置来实 现， 而终端 4可以通过在终端 4中设置一个小区测量装置来实现。 下面分别对这两个 装置进行说明。 图 5为根据本发明实施例的多频带小区间切换的指示装置的结构示意图， 如图 5 所示， 该装置主要包括： 配置模块 20， 向连接态下的终端 4配置测量任务， 其中， 所 述测量任务中配置的测量对象的载频包括： 一个载频以及该载频对应的物理频点归属 的所有频带信息中除该载频对应的频带以外的其他频带信息； 分配模块 22， 与配置模 块 20耦合， 设置为将配置的所述测量任务分配给所述终端， 其中， 所述其他频带信息 通过预定的扩展信令指示； 接收模块 24， 设置为接收所述终端 4根据所述测量任务执 行测量后上报的测量报告； 指示模块 26， 与接收模块 24耦合， 设置为根据所述测量 报告， 指示所述终端 4切换到小区。 在本实施例中， 在测量任务中配置测量对象时， 对于现有系统已有的频带信息， 以该频带信息对应的载频的形式配置， 而对于在现有系统已有的频带基础上新增的频 带的频带信息， 可以以频带列表的形式配置。 通过本实施例提供的上述装置， 将已有的频带信息及小区新增的频带信息配置在 测量任务中， 通过预定的扩展信令指示 （即背景技术中新增扩展信令） 新增的频带信 息， 并指示终端进行测量， 从而可以避免不支持解析新增的扩展信令 （即指示新增频 带的频带信息的信令） 终端测量新增频带上的频点的小区， 进而避免终端切换到该小 区上。 在本实施例的一个实施方式中， 如图 6所示， 该装置还可以包括： 判断模块 26， 设置为根据所述测量报告中包含的小区的测量结果， 判断所述终端是否能够解析预定 的扩展信令。 在本实施例中， 所述预定的扩展信令为测量对象中用于指示预定的频带
信息（即在现有系统的已有频带的基础上新增的频带信息）的信令。通过该实施方式， 基站可以获知终端是否支持解析新增的扩展信令的能力。 图 7是根据本发明实施例的小区测量装置的结构示意图， 如图 7所示， 该装置可 以包括： 接收模块 40， 设置为接收基站 2为所述终端 4配置的测量任务， 其中， 所述 测量任务中配置的测量对象包括： 一个载频以及该载频对应的物理频点归属的所有频 带信息中除该载频对应的频带以外的其他频带信息， 所述其他频带信息通过预定的扩 展信令指示； 测量模块 42， 与接收模块 40耦合， 设置为从所述基站配置的所述测量 任务中获取测量对象中的所述载频， 如果所述终端支持解析所述预定的扩展信令， 则 获取所述预定的扩展信令指示的所述其他频带信息对应的载频， 并对获取的所述载频 上的小区进行测量； 上报模块 44， 设置为在所述测量任务所指示的上报时刻到达时， 向所述基站 2上报测量报告， 其中， 所述测量报告包括： 所述测量模块测量到的满足 测量报告上报条件的各个小区的测量结果。 在本实施例中， 小区测量装置根据基站 2配置的测量任务对小区进行测量， 在终 端 4支持解析新增的扩展信令的能力情况下，才能解决到测量对象中的新增频带信息， 进而才能对新增频带对应的载频上的小区进行测量， 并上报测量报告， 从而可以避免 不支持解析新增的扩展信令的能力的终端测量第二频带上频点的小区， 进而导致终端 切换到目标小区后又回到源小区的问题。 在本实施例的一个实施方式中， 如图 8所示， 该装置还可以包括： 切换模块 46， 设置为根据所述基站的指示切换到小区。 需要说明的是， 虽然上述以多频带小区间切换的指示装置位于基站 2中， 小区测 量装置位于终端 4中为例进行说明， 但并不限于此， 在实际应用中， 多频带小区间切 换的指示装置也可以为第三方功能模块， 通过与基站 2通讯而完全上述功能， 而小区 测量装置也可以为第三方功能模块， 通过与终端 4通讯而完全上述功能。 根据本发明实施例， 还提供了一种多频带小区间切换的指示方法， 该方法可以通 过上述多频带小区间切换的指示装置实现。 图 9是根据本发明实施例的多频带小区间切换的指示方法的流程图，如图 9所示， 主要包括以下步骤： 步骤 S902， 基站向连接态下的终端配置测量任务， 其中， 测量任务中配置的测量 对象包括： 一个载频以及该载频对应的物理频点归属的所有频带信息中除该载频对应 的频带以外的其他频带信息。
在本实施例中， 基站给连接态下终端配置测量任务时， 配置测量对象为物理频带 归属的所有频带信息， 在物理频点只归属一个频带时， 可以直接在测量对象中配置与 该频带对应的载频信息， 在物理频点归属多个频带时， 可以通过载频信息 （即原来系 统已有的频带信息对应的载频信息） 和新增的频带信息列表 （即在原来系统已有的频 带的基础上新增的频带）。 步骤 S904， 基站将配置的测量任务下发给终端， 其中， 其他频带信息通过预定的 扩展信令指示。 步骤 S906， 基站接收终端根据测量任务执行测量后上报的测量报告。 步骤 S908， 基站根据测量报告， 指示终端切换到小区。 通过本实施例， 基站将已有的载频及新增的频带信息配置在测量任务中， 将新增 的频带信息通过扩展信令指示， 并指示终端进行测量， 对于不支持解析新增的扩展信 令 （即指示新增频带的频带信息的信令） 终端， 不会测量新增频带上对应的载频的小 区， 进而避免终端切换到该小区上， 对于支持解析新增的扩展信令 （即指示新增频带 的频带信息的信令） 终端， 将会测量新增频带上对应的载频的小区， 并可能切换到该 小区上。 在本实施例的一个实施方式中， 在基站将配置的测量任务下发给终端之后， 方法 还包括： 从基站配置的测量任务中获取载频， 如果终端支持解析预定的扩展信令 （测 量对象中用于指示预定的频带信息（即新增的频带信息）的信令）， 则获取预定的扩展 信令指示的其他频带信息对应的载频， 然后对获取的载频上的小区进行测量； 在有测 量报告上报时， 终端向基站上报测量报告， 其中， 测量报告可以包括： 终端测量到的 满足测量报告上报条件的各个小区的测量结果。 通过本实施方式， 在终端支持解析新 增的扩展信令的能力情况下， 同时对新增频带上对应的载频的小区进行测量， 并上报 测量报告， 从而可以避免不支持解析新增的扩展信令的能力的终端测量新增频带上对 应的载频的小区， 进而导致终端切换到目标小区后又回到源小区的问题。 在本实施例的一个实施方式中， 在基站接收终端根据测量任务执行测量后上报的 测量报告之后， 方法还包括： 基站根据测量报告中包含的小区的测量结果， 判断终端 是否能够解析预定的扩展信令。 在本实施例中， 预定的扩展信令为测量对象中用于指 示预定的频带信息的信令。 通过该实施方式， 基站可以获知终端是否支持解析预定的 扩展信令的能力。
根据本发明实施例， 还提供了一种小区测量方法， 该方法可以通过上述的上区测 量装置实现。 图 10为根据本发明实施例的小区测量方法的流程图， 如图 10所示， 主要包括以 下步骤： 步骤 S1002, 连接态下的终端接收基站为终端配置的测量任务， 其中， 测量任务 中配置的测量对象包括： 一个载频以及该载频对应的物理频点归属的所有频带信息中 除该载频对应的频带以外的其他频带信息， 其他频带信息通过预定的扩展信令指示。 其中， 本发明实施例中， 基站配置的测量对象中包括物理频点归属的所有频带信 息， 在物理频点归属多频带的情况下， 测量对象所有频带信息可以通过载频 （该载频 为与原来系统已有的频带对应的载频） 和新增频带信息 （即在原来系统已有的频带的 基础上新增的频带） 列表的形式通知， 新增频带信息列表可以包含多个频带。 步骤 S1004, 终端从基站配置的测量任务中获取测量对象中的载频， 如果终端支 持解析预定的扩展信令， 则获取预定的扩展信令指示的其他频带信息对应的载频。 在本实施例中， 终端收到基站配置的测量任务后， 从测量任务中的测量对象中获 取待测量的载频信息， 由于其他频带信息通过预定的扩展信令来指示， 因此， 只有在 终端支持解析预定的扩展信令的情况下， 才获取到新增的扩展信令指示的频带信息， 进而获取该频带信息对应的载频。 步骤 S1006, 终端对获取的载频上的小区进行测量。 步骤 S1008, 在上报测量报告时， 终端向基站上报测量报告， 其中， 测量报告包 括： 终端测量到的满足测量报告上报条件的各个小区的测量结果。 通过本实施例， 在终端支持解析新增的扩展信令的能力情况下， 同时对新增频带 上对应的载频的小区进行测量， 并上报测量报告， 从而可以避免不支持解析新增的扩 展信令的能力的终端测量新增频带上对应的载频的小区， 进而导致终端切换到目标小 区后又回到源小区的问题。 在本实施例的一个实施方式中， 在终端向基站上报测量报告之后， 方法还包括： 基站接收终端的测量报告， 根据测量报告中包含的小区的测量结果， 判断终端是否能 够解析预定的扩展信令（即背景技术中的新增的扩展信令）。通过该实施方式， 基站可 以获知终端是否支持解析新增的扩展信令的能力。
在本实施例的一个实施方式中， 在终端向基站上报测量报告之后， 该方法还可以 包括： 基站根据测量报告， 指示终端切换小区； 终端根据基站的指示切换到小区。 通 过实施方式， 基站根据终端上报的测量报告指示终端进行切换， 从而可以避免不支持 解析新增的扩展信令的终端切换到新增频带上对应载频的小区。 下面通过具体实施例进行说明。 下面实施例以小区 1 (fl， x)， 小区 2 (£2， y、 z)， 小区 3 (f2， z) 为例进行说 明。 小区 1和小区 3的系统消息广播 5中， 广播的邻区小区 2的信息包含小区 2的 EARFCN (f2， y)， 和支持的频带 z， 其中的频带 z可以是新增的频带， 放在系统消息 广播 5的扩展信令中描述的。 小区 2的系统消息广播 1中， 包含了小区 2支持的频带 和2， 其中 z可以是新增的频带， 放在系统消息广播 1的扩展的信令中描述。 终端 1 支持解析扩展信令， 是新版本的终端， 终端 2不支持解析扩展信令， 是旧版本的终端。 实施例一 本实施例以终端 1在小区 1进入连接态为例进行说明。如图 11所示， 主要包括以 下步骤： 步骤 1101， 终端 1与基站之间建立 RRC连接。 步骤 1102， 终端能力查询和上报， 终端 1上报自身的能力信息给基站， 包含支持 频带 x， z。 步骤 1103，基站给终端 1下发测量任务，测量对象的载频是 EARFCN (f2， y、 z), 报告配置是事件触发， 触发条件是事件 A3， 即邻区的信号质量高于服务小区 3dB。 步骤 1104， 终端 1执行测量， 在本实施例中， 终端 1对 EARFCN (f2， y、 z) 上 的小区进行测量。 步骤 1105， 终端 1上报测量报告， 在执行测量时， 终端 1发现小区 2 (f2， z) 和 小区 3 (f2， z)都满足事件 A3的触发条件， 上报测量报告给基站， 其中， 小区 2 (f2， z) 的信号更优。 步骤 1106， 基站收到包含小区 2 (f2， z)测量结果的测量报告， 可以推断出终端 1可以解析扩展信令， 因此基站决定将终端 1切换到小区 2 (f2， z), 终端 1成功切换 到小区 2 (£2， z) 中。
之后由于业务停止， 终端 1需要退出连接态， 进入空闲态， 终端 1通过解析小区 2的系统消息广播 1中的扩展信令， 知道小区 2支持频带 y和 z， 而终端 1是支持频带 z的， 所以可以驻留在小区 2。 实施例二 本实施例以终端 2在小区 1进入连接态为例进行说明。 参考图 11， 本实施例中， 终端 2进行切换的流程主要包括以下步骤： 步骤 1， 终端 2上报自身的能力信息给基站， 包含支持频带 x， z。 步骤 2， 基站给终端 2下发测量任务， 测量对象的载频是 EARFCN (f2， y、 z), 报告配置是事件触发， 触发条件是事件 A3， 即邻区的信号质量高于服务小区 3dB。 步骤 3， 终端 2对 EARFCN ( f2， y、 z) 上的小区进行测量， 发现小区 3 (f2， z) 满足事件 A3的触发条件， 上报测量报告给基站。 步骤 4， 基站收到测量报告， 没有包含小区 2， 可以推断终端 2可能无法解析扩展 信令因此无法测量小区 2， 或者小区 2的信号质量没有满足事件 A3的触发条件， 不管 怎样， 基站决定将终端 2切换到小区 3 (f2， z), 终端 2成功切换到小区 3 (f2， z)中。 之后由于业务停止， 终端 2需要退出连接态， 进入空闲态， 终端 2通过解析小区
3的系统消息广播 1， 知道小区 3支持频带2， 而终端 2是支持频带 z的， 所以可以驻 留在小区 3。 从以上的描述中， 可以看出， 通过上述实施例之一提供的技术方案基站将已有的 频带信息 （通过载频描述） 及小区新增的频带信息配置在测量任务中， 指示终端进行 测量， 从而可以避免不支持解析新增的扩展信令（即指示新增频带的频带信息的信令) 终端测量新增频带上的载频的小区， 进而避免终端切换到该小区上。 工业实用性 本发明提供的技术方案， 基站在下发测量任务时， 在测量对象中配置当前已有的 频带信息对应的载频及新增的频带信息，并通过新增的扩展信令指示新增的频带信息， 而不是在测量对象中直接将新增的频带信息对应的载频下发给终端， 通过这种方式， 可以避免终端切换到无法驻留的小区。 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， 并且在某些情况下， 可以以不同于此处 的顺序执行所示出或描述的步骤， 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。 凡在本发明的精神和原则之内， 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。
