一种获取网络状态信息的方法及装置 技术领域
本发明涉及智能移动终端技术， 尤其涉及一种当小区状态发生变化后, 移动终端获取网络状态信息的方法及装置。 背景技术
由于智能移动终端功能强大、 可操作性强、 能方便的安装第三方软件， 越来越多地受到了人们的重视。 智能手机的市场前景也越来越广泛， 而通 用联机框架 （GCF , Global Certification Forum ) 测试是宽带码分多址 ( WCDMA )移动终端进入商用之前重要的测试。 当移动终端所处的小区 网络状态发生变化后， 移动终端是否能够正确感知到所处的小区网络状态 并且将对应的网络状态信息写入用户身份识别模块 （SIM , Subscriber Identity Module )卡。 延伸到未来， 可以理解为网络运营商是否可以将网络 信息通过移动终端写入 SIM卡中， 让移动终端充分支持终端软件和定制分 离的实现趋势。
本文基于 GSM通用标准认证 SIM卡支持能力集（ STK, Mobile Station Test Suite )测试的一个重要测试项， 以现有高通平台为例， 图 1为现有获 取网络状态信息的示意图， 如图 1 所示， 获取网络状态的过程大致包括： 高通 SIM卡支持能力集（GSTK )模块向移动性管理（MM )模块注册网络 状态， 当小区网络发生切换后， GSTK模块在移动性管理空闲（MM— IDLE ) 状态变化的地方处理网络状态命令， 然后调用高通接口通过 SIM模块， 将 变化后的网络状态写入 SIM卡。
而在实际网络环境中， 当小区状态发生变化后， GSTK模块在对应的 MM— IDLE状态变化的地方处理网络状态命令时， 接收不到网络状态的变 化，也就是说， 不能获取变化后的网络状态信息， 进而不能正确的驱动 SIM 模块将对应的网络状态写入 SIM卡中。
从现有技术的实现过程来看， 目前当小区状态发生变化后移动终端获 取网络状态信息的方法， 不能保证 GSTK模块获取正确的网络状态信息， 也不能将正确获知小区发生变化后的网络状态更新到对应的 SIM卡上。 发明内容
有鉴于此， 本发明的主要目的在于提供一种移动终端获取网络状态信 息的方法及装置， 能够获取正确的网络状态信息。
为达到上述目的， 本发明的技术方案是这样实现的：
本发明提供了一种获取网络状态信息的方法， 包括：
GSTK模块向连接性管理（CM )模块注册网络状态通知；
CM模块记录的网络状态发生变化时通知 GSTK模块， GSTK模块获得 发生变化的网络状态信息。
其中， GSTK模块向 CM模块注册网络状态通知之前， 该方法还包括： 移动终端上电开机后， 所述 CM模块向网络模块注册回调函数； 当网络模 块搜索到该小区所在的网络时， 网络模块存储当前的网络状态并通过回调 函数通知 CM模块； 当用户终端所在网络状态发生变化后， 网络模块存储 变化后的网络状态， 并通过回调函数通知 CM模块。
其中， GSTK模块获得发生变化的网络状态信息之后， 该方法还包括： 所述 GSTK模块存储获得的网络状态。

从上述技术方案可以看出， 本发明由 GSTK模块向连接性管理（ CM ) 模块注册网络状态通知，在 CM模块记录的网络状态发生变化时通知 GSTK 模块。 由于每次网络状态发生变化后， CM模块上报的状态总是正确的， 因 此， 通过本发明方法， GSTK模块准确感知到当前网络模块状态的变化， 从 而保证移动终端能够获得正确的网络状态信息。
进一步地， 通过本发明提供的将网络模块变化后的网络状态写入 SIM 卡的方法， 可以让运营商通过 SIM卡状态了解到当前网络的变化状态， 由 此也推动了未来移动终端软件和运营商定制相互分离的发展。 附图说明

图 2为本发明获取网络状态信息的流程图， 如图 2所示， 包括以下步 骤：
步骤 200: GSTK模块向 CM模块注册网络状态通知。
这里，由于每次网络状态发生变化后， CM模块上报的状态总是正确的， 因此， 本步骤中， GSTK模块可以通过向 CM模块注册回调函数来指令 CM 模块在网络状态发生变化时， 将变化后的网络状态通知给 GSTK模块。 对 于注册回调函数的具体实现方法， 属于本领域技术人员的惯用技术手段， 这里不再赘述。
本步骤之前还包括： 移动终端插入 SIM卡， 移动终端置于某小区的网 络覆盖范围内， 移动终端上电开机后， CM模块向网络模块注册回调函数， 希望网络模块在网络状态发生变化后给出通知， 当网络模块搜索到该小区 所在的网络时， 网络模块存储当前的网络状态并通过回调函数通知 CM模 块； 当用户终端移动到另一小区后， 网络模块存储变化后的网络状态， 并 通过回调函数通知 CM模块网络状态已经发生变化。
步骤 201： CM模块记录的网络状态发生变化时通知 GSTK模块， GSTK 模块获得发生变化的网络状态信息。
通过本发明方法， GSTK模块能准确感知到当前网络模块状态的变化， 从而保证移动终端能够获得正确的网络状态信息。
进一步的， 本发明方法还包括步骤 202: GSTK模块存储获得的网络状 态。 步骤 202具体可以是： GSTK模块得到网络状态发生变化后， 通过已有 GSKT封装（Envelop )命令将当前的网络状态存储到移动终端上， 具体实 现是将获取的网络状态类型修改为小区位置信息改变类型， 同时调用高通 GSTK Envelop命令处理函数，将对应的网络状态信息通过 SIM模块接口函 数写入 SIM卡。
具体本步骤中如何存储获得的网络状态信息， 属于本领域技术人员惯 用技术手段， 这里不再赘述。
通过本发明提供的将网络模块变化后的网络状态写入 SIM卡的方法， 可使运营商通过 SIM卡状态了解到当前网络的变化状态， 进而推动未来移 动终端软件和运营商定制相互分离的发展。
针对本发明方法， 还提供一种获取网络状态信息的装置， 该装置设置 在移动终端中， 至少包括 CM模块和 GSTK模块； 其中，
GSTK模块， 用于向 CM模块注册网络状态通知， 接收来自 CM模块 的通知， 获得发生变化的网络状态信息；
CM模块， 用于在记录的网络状态发生变化时通知 GSTK模块。
本发明装置还包括网络模块， 用于在移动终端插入 SIM卡， 移动终端 置于某小区的网络覆盖范围内， 移动终端上电开机后， 接收来自 CM模块 的注册回调函数； 当搜索到小区所在的网络时， 存储当前的网络状态并通 过回调函数通知 CM模块； 相应的， CM模块， 进一步用于向网络模块发送 注册回调函数； 接收来自网络模块的通知。
所述 GSTK模块， 还用于存储获得的网络状态。
本发明装置还包括 SIM模块， 用于将来自 GSTK的网络状态信息通过 SIM模块接口函数写入 SIM卡； GSTK模块，具体用于将获取的网络状态类型修改为小区位置信息改变 类型， 调用高通 GSTK Envelop命令处理函数， 将对应的网络状态信息发送 给 SIM模块。
下面结合附图和实施例对本发明方法进行详细描述。
图 3 为本发明获取网络状态信息的实施例的示意图， 本实施例中以高 通 7225平台 GSTK模块为例， 如图 3所示， 包括以下处理：
首先， 移动终端插入 SIM卡， 假设移动终端位于小区一的网络覆盖范 围内。 移动终端上电开机后， CM模块向网络模块注册回调函数， 希望网络 模块在网络状态发生变化后告知； GSTK模块向 CM模块注册回调函数， 请求 CM模块得到网络变化状态后告知。
网络模块搜索到小区一所在的网络时， 存储当前的网络状态并通过回 调函数通知 CM模块， CM模块通过回调函数将收到的网络状态通知 GSTK 模块， GSTK模块使用 Envelop命令将当前的网络状态写入 SIM卡。
之后， 假设用户使移动终端离开小区一的网络覆盖范围， 进入小区二 的网络覆盖范围， 此时， 网络模块接收到小区一的网络信号减弱， 但是接 收到小区二的网络信号增强， 网络模块分析判断当前网络的信号状态已经 发生变化， 于是关闭对小区一网络信号的处理， 转入对小区二的网络信号 处理；网络模块存储变化后的网络状态， 并通过回调函数通知 CM模块网络 状态已经发生变化， CM模块获知网络状态发生变化后，通过回调函数通知 GSTK模块当前的网络状态发生了变化。
这样， GSTK模块感知到网络状态已发生变化，将网络状态相关的数据 封装成 Envelop数据包， 使用 GSTK Envelop命令通过 SIM模块处理， SIM 模块会找到 SIM卡对应的 SIM卡文件区域， 将网络 Envelop数据包中的网 络相关的信息写到 SIM卡对应的文件区域上， 更新 SIM卡文件区域。
本发明方法弥补了现有平台 GSTK模块的处理缺陷， 使得 GSTK模块 能准确感知到当前网络状态的变化。 当移动终端所在的小区由小区一切换 到小区二后， 网络模块通过 CM模块将正确的网路状态传递给了 GSTK模 块， 让 GSTK模块正确感知移动终端所处小区网络状态的变化， 并获取网 络模块中的最新网络状态。 随后， GSTK模块使用 Envelop命令通过 SIM 模块将准确的网络状态信息写入 SIM卡对应的文件区域中。 通过本发明方 法， 保证了当前网络的最新状态被正确地存储到 SIM卡上。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围， 凡在本发明的精神和原则之内所作的任何修改、 等同替换和改进 等， 均应包含在本发明的保护范围之内。
