本发明涉及通信领域， 尤其涉及一种在共享网络中确定运营商的方法及 装置。 背景技术
3GPP ( The 3rd Generation Partner Project,第三代合作伙伴计划）在 Rel，6 版本协议中规定了 MOCN (Multi-Operator Core Network,多运营商核心网络)特 性， 允许多个运营商共享 RAN(Radio Access Network,接入网）， 以及载频、 小 区。 相对于其他共享接入网方式， MOCN的主要特征是在共享接入网节点的 基础上， 进一步共享了载频以及小区， 使得运营商可以使用公共的无线网络 向各自的归属用户以及签约漫游用户提供服务， 即归属不同运营商的用户设 备可以在一个小区中接入并获得特定运营商提供的服务。
MOCN共享小区技术允许不同运营商可以共享小区但核心网各自独立。 BSS ( Base Station Subsystem, 基站子系统 )通过对用户的用户标识进行识别， 判断出该用户所属的运营商， 并能将该用户的业务正确转发给对应的核心网。 不同运营商共享小区以后， 频率资源、 信道资源都可以进行共享。
当移动用户进入该共享小区后， 首先要确定为该移动用户服务的运营商， 才能保证移动终端和核心网之间的正常通信。 为确定为移动终端服务的运营 商， 现有技术中釆用如下的方法， 具体为：
首先由 BSS设置移动用户的用户标识和运营商的对应关系： 其中， 该移 动用户的用户标识由为其服务的运营商的核心网分配的， 可能为 IMSI ( International Mobile Subscriber Identity, 移动用户全球识别码）或者 TMSI
( Temporary Mobile Subscriber Identify , 临时移动用户识另 ll号码 ) /P-TMSI(Packet Temperate Mobile Subs cription Identity,分组临时移动用户识别 码）， 其中 TMSI/P-TMSI中可以解析出 NRI(Network Resource Identifier,网络资 源标识);具体由 BSS的 BSC ( Base Station controller, 基站控制器）侧配置 IMSI 和运营商对应关系以及路由比例关系， NRI和核心网网元的对应关系， 一个核 心网网元只属于一个运营商， 对应到核心网网元即可对应到运营商。
当移动用户初始进入 BSS的覆盖范围内， 发起位置区更新时， BSS首先查 找移动移动终端中是否携带 IMSI, 若携带了 IMSI, 则 BSS根据 IMSI查找配置 的路由比例关系， 确定该移动终端对应的运营商； 如果移动终端没有携带 IMSI, 那么 BSS就向移动终端索取 IMSI, 从而确定该移动终端对应的运营商。
在实施上述识别为移动终端服务的运营商的过程中， 发明人发现现有技 术中至少存在如下问题， 移动终端一般只在开机注册时发送包含有 IMSI用户 标识的位置区更新、 路由区更新或附着请求， 按照上述方案， 移动终端每次 位置区更新、路由区更新或附着请求时， BSS均需要发起请求来获取用户标识， 增加了空口消息流量和用户的接入时延。 发明内容
本发明的实施例提供一种在共享网络中确定运营商的方法及装置， 减少 了空口消息流量和用户的接入时延。
为达到上述目的， 本发明的实施例釆用如下技术方案：

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作 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。
实施例 1
本发明实施例提供一种在共享网络中确定运营商的方法， 如图 1 所示， 该方法包括：
101、 接收用户终端发起的接入消息， 所述接入消息中包括所述用户终端 保存的最新位置区信息和所述用户终端的临时识别码；
其中， 所述接入消息可以为但不局限于以下的接入消息： 用户终端在基 站子系统发起的位置区更新、 路由区更新或附着请求等接入消息。
102、 根据所述用户终端保存的最新位置区信息检测用户终端当前所处的 位置区和所述用户终端保存的最新位置区是否在同一路由共享区。
其中， 在根据所述用户终端保存的最新位置区信息检测用户终端当前所 处的位置区和所述用户终端保存的最新位置区是否在同一路由共享区时可以
釆用如下方法：
根据所述获取的所述用户终端当前所处的位置区信息和所述用户终端保 存的最新位置区信息， 以及预设的路由共享区与位置区的对应关系， 判断所 述用户终端当前所处的位置区和所述用户终端保存的最新位置区是否在同一 路由共享区。 其中， 所述预设的路由共享区与位置区的对应关系可以由基站 子系统的基站控制器在执行本发实施例的步骤之前设置； 所述用户终端当前 所处的位置区信息由网络侧在执行本发实施例的步骤之前获取。
103、 若检测到所述用户终端当前所处的位置区和所述用户终端保存的最 新位置区在同一路由共享区， 基站控制器根据所述用户终端的临时识别码确 定为所述用户终端服务的运营商。
其中， 所述用户终端的临时识别码包含在所述用户终端发起的接入消息 中， 可能为 TMSI或 P-TMSI, 所述 TMSI或 P-TMSI的第 14到 23比特位存 储有 NRI, NRI和核心网网元具有——对应的关系， 一个核心网网元只属于 一个运营商， 对应到核心网网元即可对应到运营商； 当需要根据 TMSI 或 P-TMSI确定为所述用户终端服务的运营商时， 仅需要根据协议从 TMSI 或 P-TMSI中的第 14到 23比特位进行解析便可以得到该 NRI。
所述根据用户终端的临时识别码确定为所述用户终端服务的运营商具体 可以是， 对所述用户终端的临时识别码进行解析得到网络资源标识 NRI; 根 据预设置的网络资源标识 NRI与核心网的对应关系， 以及所述解析得到的网 络资源标识， 确定为所述用户终端服务的运营商。
上述各步骤的执行可以由基站子系统的基站控制器执行。
本发明实施例中， 在基站控制器接收到用户终端的接入消息后， 判断发 起接入请求的用户终端当前所处的位置区和所述用户终端上报的保存的最新 位置区是否在同一路由共享区， 若在同一路由共享区， 则根据所述用户终端 的临时识别码确定为所述用户终端服务的运营商； 与现有技术中当检测当所 述接收到的用户终端的接入消息中不包含移动用户全球识别码时， 就向用户
终端发起身份请求要求获取用户终端的移动用户全球识别码相比， 本发明实 施例在接收到的用户终端的接入消息后， 不会立即向用户终端发起身份请求， 而是根据路由共享区的特性， 判断发起接入请求的用户终端当前所处的位置 区和所述用户终端上报的保存的最新位置区是否在同一路由共享区， 若用户 终端当前的位置区和所述用户终端之前所处的位置区在同一路由共享区， 则 根据所述用户终端的临时识别码确定为其服务的运营商， 而不需要向用户终 端发起身份请求， 从而显著减少了向用户终端发起身份请求的次数， 减少了 基站控制器与用户终端之间的信令交互， 使空口消息流量和用户的接入时延 减少。
其中， 在执行步骤 101接收用户终端发起的接入消息之前， 本发明还进 一步包括： 设置路由共享区。
所述路由共享区可以由基站子系统的基站控制器设置， 该路由共享区以 位置区为粒度划分， 在一个路由共享区内包含至少一个位置区， 该位置区为 物理服务小区， 其有一定的服务覆盖范围， 可以为但不局限于宏小区； 在一 个该路由共享区中， 同一 IMSI号段的用户路由比例关系是相同的， 所述路由 共享区中的位置区， 可以由共享运营商划定， 如： 在这些位置区下， 漫游用 户比例要求相同、 共享运营商中各自运营商自己独立所有网络下的位置区等。
设置该路由共享区， 可以使运营商之间实现资源共享， 使属于不同运用 商的用户终端漫游到该共享区中的任何一个位置区时， 即使用户终端向基站 服务器发起的接入请求中不存在 IMSI, 基站服务器也可以根据各运营商的核 心网为该用户终端设定的用户临时识别码确定为该用户终端服务的运营商， 使得基站控制器， 不用再接收到的接入消息中没有 IMSI时， 向用户终端索要 用户终端的 IMSI, 从而减少了用户终端和基站控制器的信令交互， 使空口消 息流量和用户的接入时延减少。
进一步， 若基站控制器检测到所述用户终端当前所处的位置区和所述用 户终端之前所处的位置区不在同一路由共享区， 则向用户终端发起身份请求，
要求获取所述用户终端的移动用户全球识别码， 并根据所述获取的用户终端 的移动用户全球识别码确定为所述用户终端服务的运营商。 在根据所述获取 的用户终端的移动用户全球识别码确定为所述用户终端服务的运营商后， 该 基站控制器利用所述获取的用户终端的移动用户全球识别码替代所述接入消 息中的用户终端的临时识别码； 将所述包含所述获取的用户终端的移动用户 全球识别码的接入消息发送给与所述确定的为所述用户终端服务的运营商对 应的核心网， 以便核心网为该用户终端月良务。
当基站控制器检测到所述用户终端当前所处的位置区和所述用户终端之 前所处的位置区不在同一路由共享区时， 才向用户终端发起身份请求， 要求 获取所述用户终端的移动用户全球识别码， 并且在根据所述获取的用户终端 的移动用户全球识别码确定为所述用户终端服务的运营商后， 该基站控制器 利用所述获取的用户终端的移动用户全球识别码替代所述接入消息中的用户 终端的临时识别码， 并将该用户终端的移动用户全球识别码发送给核心网， 以便核心网为该用户终端服务； 由于核心网可以通过该户终端的移动用户全 球识别码唯一的确定用户终端， 避免了核心网根据用户终端的临时识别码不 能唯一的确定用户终端时， 向用户终端索要用户终端的移动用户全球识别码， 从而减少了核心网与用户终端之间的信令交互。
实施例 2
本发明实施例提供一种在共享网络中确定运营商的方法， 如图 2 所示， 该方法包括：
201、 基站子系统的基站控制器设置所述共享网络下的路由共享区。
其中， 所述路由共享区以位置区为粒度划分， 一个路由共享区包含至少 一个该位置区， 该位置区为物理服务小区， 其有一定的服务覆盖范围， 可以 为但不局限于宏小区； 在一个所述共享区内， 同一 IMSI号段的用户路由比例 关系是相同的， 所述共享网络下的位置区， 可以由共享运营商划定， 如： 在 这些位置区下， 漫游用户比例要求相同、 共享运营商中各自运营商自己独立
所有网络下的位置区等。 在设置路由共享区的同时， 该基站控制器也确定了 路由共享区与位置区的对应关系。
202、 当用户终端向基站子系统发起接入请求时， 基站控制器接收用户终 端发起的接入消息， 所述接入消息中包括所述用户终端保存的最新位置区信 息和所述用户终端的临时识别码； 其中， 所述接入消息可以为但不局限与以 下的接入消息： 用户终端在基站子系统发起的位置区更新、 路由区更新或附 着请求等接入消息。
203、 判断所述接收到的接入消息中是否包含所述用户终端的 IMSI ( International Mobile Subscriber Identity, 移动用户全球识别码 ); 若判定所述 接入消息中没有包含所述用户终端的 IMSI, 则执行步骤 204; 若判定所述接 入消息中包含所述用户终端的 IMSI , 则执行步骤 208。
其中， IMSI由移动国家码、 移动网络码和移动用户识别码三部分组成， 共 15位。
204、 基站控制器根据所述用户终端保存的最新位置区信息检测所述用户 终端当前所处的位置区和所述用户终端保存的最新位置区是否在同一路由共 享区； 若检测到用户终端当前所处的位置区和所述用户终端保存的最新位置 区在同一路由共享区， 则执行步骤 205; 若检测到所述用户终端当前所处的位 置区和所述用户终端保存的最新位置区不在同一路由共享区， 则执行步骤 206。
其中， 基站控制器在检测用户终端当前所处的位置区和所述用户终端保 存的最新位置区是否在同一路由共享区如实施例 1 中的步骤 102中所述， 此 处将不再赘述。
205、 根据所述用户终端的临时识别码确定为所述用户终端服务的运营 商。
其中， 所述根据所述用户终端的临时识别码确定为所述用户终端服务的 运营商的具体方式如实施例 1中的 103所述步骤， 此处将不再赘述。
206、 基站控制器向用户终端发起身份请求， 要求获取所述用户终端的 IMSI, 并根据所述获取的用户终端的 IMSI确定为所述用户终端服务的运营 商。
其中，根据所述获取的用户终端的 IMSI确定为所述用户终端服务的运营 商具体包括： 根据预设置的用户终端的 IMSI对应的路由比例关系， 以及所述 获取的用户终端的 IMSI, 确定为所述用户终端服务的运营商。
207、 在根据所述获取的用户终端的 IMSI确定为所述用户终端服务的运 营商后， 该基站控制器利用所述获取的用户终端的 IMSI替代所述接入消息中 的用户终端的临时识别码； 将所述包含所述获取的用户终端的 IMSI的接入消 息发送给与所述确定的为所述用户终端服务的运营商对应的核心网， 以便核 心网为该用户终端服务。
208、 根据所述用户终端的 IMSI确定为所述用户终端服务的运营商。 其 具体方法参考步骤 206中的叙述， 此处将不再赘述。
本发明实施例中， 在基站控制器接收到用户终端的接入消息后， 首先判 断所述接收到的接入消息中是否包含用户终端的 IMSI, 当不包含用户终端的 IMSI时， 进一步判断用户终端当前所处的位置区和所述用户终端保存的最新 位置区是否在同一路由共享区， 若在同一路由共享区， 则根据所述用户终端 的临时识别码确定为所述用户终端服务的运营商； 与现有技术中当检测当所 述接收到的用户终端的接入消息中不包含 IMSI时， 就向用户终端发起身份请 求要求获取用户终端的 IMSI相比，本发明实施例在接收到的用户终端的接入 消息中不包含用户终端的 IMSI时， 不会立即向用户终端发起身份请求， 而是 进一步判断用户终端当前的位置区和所述用户终端保存的最新位置区是否在 同一路由共享区， 若用户终端当前的位置区和所述用户终端保存的最新位置 区在同一路由共享区， 则根据所述用户终端的临时识别码确定为其服务的运 营商， 而不需要向用户终端发起身份请求， 从而显著减少了向用户终端发起 身份请求的次数， 减少了基站控制器与用户终端之间的信令交互， 使空口消
息流量和用户的接入时延减少。
并且， 本发明实施例在接收到的用户终端的接入消息中不包含用户终端 的 IMSI, 并且用户终端当前的位置区和所述用户终端保存的最新位置区不在 同一路由共享区时， 才向用户终端发起身份请求要求获取所述用户终端的 IMSI,从而根据所述获取的用户终端的 IMSI进而确定为该用户终端服务的运 营商， 显著减少了向用户终端发起身份请求的次数， 减少了基站控制器与用 户终端之间的信令交互， 从而减少了空口消息流量和用户的接入时延。
进一步，与现有技术中由于用户终端的 TMSI或 P-TMSI存在着由其他核 心网分配的情况， 如果其他核心网和 BSS的共享运营商的核心网无接口， 则 这些用户终端的 TMSI或 P-TMSI无法为当前选择到的核心网元识别， 即不能 正确的确定为该用户服务的运营商； 此时当前选择到的核心网会主动发起用 户标识的查询， 使得核心网和用户终端之间出现大量的信令交互； 本发明实 施例中， 当判定户终端当前的位置区和所述用户终端之前所处的位置区不在 同一路由共享区时的情况便属于上述现有技术中存在的问题， 当存在此中问 题时， 该基站控制器利用所述获取的用户终端的移动用户全球识别码替代所 述接入消息中的用户终端的临时识别码， 并将该用户终端的移动用户全球识 别码发送给核心网， 以便核心网为该用户终端服务； 由于核心网可以通过该 户终端的移动用户全球识别码唯一的确定用户终端， 避免了核心网根据用户 终端的临时识别码不能唯一的确定用户终端时， 向用户终端索要用户终端的 移动用户全球识别码， 从而减少了核心网与用户终端之间的信令交互。
实施例 3
本发明实施例提供在共享网络中确定运营商的装置， 该装置可以为基站 子系统的基站控制器， 如图 3所示， 该装置包括： 接收单元 31、 检测单元 32 和第一确定单元 33。

其中， 所述路由共享区可以由基站子系统的基站控制器设置， 具体由该 基站控制器添加的设置单元 34设置， 该路由共享区以位置区为粒度划分， 在 一个路由共享区内包含至少一个位置区， 该位置区为物理服务小区， 其有一 定的服务覆盖范围， 可以为但不局限于宏小区； 在一个该路由共享区中， 同 一 IMSI号段的用户路由比例关系是相同的， 所述路由共享区中的位置区， 可 以由共享运营商划定， 如： 在这些位置区下， 漫游用户比例要求相同、 共享 运营商中各自运营商自己独立所有网络下的位置区等。
其中， 所述检测单元 32在根据所述用户终端保存的最新位置区信息检测 用户终端当前所处的位置区和所述用户终端保存的最新位置区是否在同一路 由共享区时具体为： 根据所述用户终端当前所处的位置区信息和所述用户终 端保存的最新位置区信息， 以及预设的路由共享区与位置区的对应关系， 判 断所述用户终端当前所处的位置区和所述用户终端保存的最新位置区是否在 同一路由共享区。 其中， 所述预设的路由共享区与位置区的对应关系可以由 基站子系统的基站控制器在执行本发实施例的步骤之前设置的。
其中， 所述第一确定单元 33包括： 解析模块 331和确定模块 332。
所述第一确定单元 33在根据用户终端的临时识别码确定为所述用户终端 服务的运营商时， 首先通过解析模块 331 对所述用户终端的临时识别码进行 解析得到网络资源标识； 在得到网络资源标识后， 确定模块 332用于根据预 设置的网络资源标识与核心网的对应关系， 以及所述解析模块 331 解析得到
的网络资源标识， 确定为所述用户终端服务的运营商。 其中， 所述用户终端 的临时识别码可能为 TMSI或 P-TMSI, 所述 TMSI或 P-TMSI的第 14到 23 比特位存储有 NRI, NRI和核心网网元具有——对应的关系， 一个核心网网 元只属于一个运营商， 对应到核心网网元即可对应到运营商； 当需要根据 TMSI或 P-TMSI确定为所述用户终端服务的运营商时， 仅需要所述解析模块 331根据协议从 TMSI或 P-TMSI中的第 14到 23比特位进行解析便可以得到 该環。
进一步， 在所述检测单元 32检测到用户终端当前所处的位置区和所述用 户终端保存的最新位置区不在同一路由共享区时， 该装置如图 4 所示， 还包 括： 获取单元 35和第二确定单元 36。
在所述检测单元 32检测到用户终端当前所处的位置区和所述用户终端保 存的最新位置区不在同一路由共享区时， 所述获取单元 35用于向所述用户终 端发起身份请求， 要求获取所述用户终端的 IMSI; 在获取了所述用户终端的 IMSI后， 第二确定单元 36用于根据所述获取单元 35获取的用户终端的移动 用户全球识别码确定为所述用户终端服务的运营商， 从而实现基站控制器确 定为该用户终端服务的运营商， 实现该确定的运营商的核心网和该用户终端 之间的通信。
可选的， 为了使为所述用户终端服务的核心网可以根据基站控制器上报 的用户终端的用户标识， 唯一的确定该用户终端， 该装置如图 5 所示， 还包 括： 替换单元 37和发送单元 38。
所述替换单元 37,在所述第二确定单元 35根据所述获取的用户终端的移 动用户全球识别码确定为所述用户终端服务的运营商后， 利用所述获取的用 户终端的移动用户全球识别码替代所述接入消息中的用户终端的临时识别 码； 发送单元 38, 用于将所述包含所述获取的用户终端的移动用户全球识别 码的接入消息发送给与所述确定的为所述用户终端服务的运营商对应的核心 网， 由核心网根据上报的用户终端的移动用户全球识别码唯一的确定该用户

可选的， 在所述接收单元 31接收到用户终端发起的接入消息后， 在检测 用户终端当前所处的位置区和所述用户终端保存的最新位置区是否在同一路 由共享区之前， 该装置还可以先判断所述接收到的接入消息中是否包含所述 用户终端的移动用户全球识别码， 进而进一步减少用户接入的延时， 此时该 装置如图 6所示还包括： 判断单元 39。
所述判断单元 39用于判断所述接收单 31接收到的接入消息中是否包含 所述用户终端的 IMSI , 该 IMSI由移动国家码、 移动网络码和移动用户识别 码三部分组成， 共 15位； 在所述判断单元 39判定所述接入消息中没有包含 用户终端的 IMSI时， 该装置调用所述检测单元 32检测用户终端当前所处的 位置区和所述用户终端保存的最新位置区是否在同一路由共享区， 并执行相 应的操作。
在所述判断单元 39判定所述接入消息中包含用户终端的 IMSI时， 该装 置不用调用所述检测单元 32测用户终端当前所处的位置区和所述用户终端保 存的最新位置区是否在同一路由共享区， 直接根据所述接入消息中的用户终 端的 IMSI确定为该用户终端服务的运营商。 其中根据用户终端的 IMSI确定 为该用户终端服务的运营商可以釆用现有技术中的方法， 具体包括： 根据预 设置的用户终端的 IMSI对应的路由比例关系， 以及所述获取的用户终端的 IMSI, 确定为所述用户终端服务的运营商。
本发明实施例中， 在基站控制器接收到用户终端的接入消息后， 首先判 断所述接收到的接入消息中是否包含用户终端的 IMSI, 当不包含用户终端的 IMSI时， 进一步判断用户终端当前所处的位置区和所述用户终端保存的最新 位置区是否在同一路由共享区， 若在同一路由共享区， 则根据用户终端的临 时识别码确定为所述用户终端服务的运营商； 与现有技术中当检测当所述接
收到的用户终端的接入消息中不包含 IMSI时， 就向用户终端发起身份请求要 求获取用户终端的 IMSI相比，本发明实施例在接收到的用户终端的接入消息 中不包含用户终端的 IMSI时， 不会立即向用户终端发起身份请求， 而是进一 步判断用户终端当前的位置区和所述用户终端保存的最新位置区是否在同一 路由共享区， 若用户终端当前的位置区和所述用户终端保存的最新位置区在 同一路由共享区， 则根据用户终端的临时识别码确定为其服务的运营商， 而 不需要向用户终端发起身份请求， 从而显著减少了向用户终端发起身份请求 的次数， 减少了基站控制器与用户终端之间的信令交互， 使空口消息流量和 用户的接入时延减少。
并且， 本发明实施例在接收到的用户终端的接入消息中不包含用户终端 的 IMSI, 并且用户终端当前的位置区和所述用户终端保存的最新位置区不在 同一路由共享区时， 才向用户终端发起身份请求要求获取用户终端的 IMSI, 从而根据所述获取的用户终端的 IMSI进而确定为该用户终端服务的运营商， 显著减少了向用户终端发起身份请求的次数， 减少了基站控制器与用户终端 之间的信令交互， 从而减少了空口消息流量和用户的接入时延。
进一步，与现有技术中由于用户终端的 TMSI或 P-TMSI存在着由其他核 心网分配的情况， 如果其他核心网和 BSS的共享运营商的核心网无接口， 则 这些用户终端的 TMSI或 P-TMSI无法为当前选择到的核心网元识别， 即不能 正确的确定为该用户服务的运营商； 此时当前选择到的核心网会主动发起用 户标识的查询， 使得核心网和用户终端之间出现大量的信令交互； 本发明实 施例中， 当判定户终端当前的位置区和所述用户终端保存的最新位置区不在 同一路由共享区时的情况便属于上述现有技术中存在的问题， 当存在此中问 题时， 该基站控制器利用所述获取的用户终端的移动用户全球识别码替代所 述接入消息中的用户终端的临时识别码， 并将该用户终端的移动用户全球识 别码发送给核心网， 以便核心网为该用户终端服务； 由于核心网可以通过该 户终端的移动用户全球识别码唯一的确定用户终端， 避免了核心网根据用户
终端的临时识别码不能唯一的确定用户终端时， 向用户终端索要用户终端的 移动用户全球识别码， 从而减少了核心网与用户终端之间的信令交互。
通过以上的实施方式的描述， 所属领域的技术人员可以清楚地了解到本 发明可借助软件加必需的通用硬件的方式来实现， 当然也可以通过硬件， 但 很多情况下前者是更佳的实施方式。 基于这样的理解， 本发明的技术方案本 质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来， 该 计算机软件产品存储在可读取的存储介质中， 如计算机的软盘， 硬盘或光盘 等， 包括若干指令用以使得一台计算机设备（可以是个人计算机， 服务器， 或者网络设备等）执行本发明各个实施例所述的方法。
以上所述， 仅为本发明的具体实施方式， 但本发明的保护范围并不局限 于此， 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可轻易 想到变化或替换， 都应涵盖在本发明的保护范围之内。 因此， 本发明的保护 范围应以所述权利要求的保护范围为准。
