图 1是本发明实施例移动终端组成示意图；
图 2是本发明实施例移动终端自适应提升下载速率的方法流程示意图； 图 3是本发明实施例移动终端的速率检测模块工作流程示意图。 具体实施方式
本发明技术方案的思想是： 在移动终端上增设用于对于网络信号进行 判定的网络检测模块和用于进行速率测定的速率检测模块， 对移动终端所 在周围无线网络检测并检测各无线网络的网络速率， 依据检测到的各无线 网络的网络速率， 自适应地将移动终端进行无线数据服务的链路切换到最 佳链路上， 从而实现对于用户下载速率提升的自适应控制功能。
下面结合附图和实施例对本发明技术方案故详细说明。 应当理解， 此 处所描述的优选实施例仅用于说明和解释本发明， 并不用于限定本发明。
图 1为本发明实施例移动终端组成示意图， 如图 1所示， 该移动终端 包括： 网络检测模块、 用户业务检测单元、 速率检测模块、 链路质量判断 单元、 以及链路切换裁定单元； 其中，
网络检测模块， 用于对于移动终端网络周围的无线信号进行检测； 具体地， 在移动终端开机运行后， 网络检测模块完成相关初始化工作 置于后台进行运行， 并依据用户当前所处的网络环境， 主动搜索并在后台 建立合适的网络连接。 网络检测模块可以依据用户的设定或自主根据用户 是否进行数据业务的请求来进行网络能力的判定， 网络检测模块具有识别 不同网络特性的能力。
用户业务检测单元， 用于判定用户是否需要进行数据服务， 若用户需 要进行数据服务， 则相关单元需要检测出相关请求；
具体地， 用户业务检测单元可以通过检测用户终端应用中的数据服务 是否开启即可实现相关操作的判定，比如：检测是否有 http请求、或 SCOKET 类相关操作信息来判定。
链路质量判断单元， 用于在确定用户需要进行数据服务后， 即用户开 启相关数据服务业务后， 检测相关无线网络的链路质量； 这里， 链路质量判断单元通过检测可以获得服务的相关网络的链路质 量、 以及是否可以提供相关的数据服务能力。
链路质量判断单元可以通过对移动终端周围不同网络的无线链路进行 判断， 来检测相关链路的链路质量， 链路质量包括： 链路是否可用、 是否 可以进行有效的连接建立响应、 或是否可以提供相关的数据服务。
链路质量判断单元在检测各个网络的链路质量时， 可以通过发送相关
PING指令到特定网站地址， 并根据包的响应延迟来确定当前不同网络的链 路质量。 其中， Ping 指令作为一个常用的网络测试指令， 可以用来对于链 路质量和相关网站进行简单的测试工作， 当使用不同的相关指令参数时， 可以获得不同的响应信息， 如 TTL时间、 ECO时间、 以及通过发送不同的 包得到相关的反馈时间后， 计算出链路的速度等。
其中， 链路质量判断单元在判断链路是否可以提供数据服务能力时， 可以通过与无线网络交互的信令消息来进行判定的。
速率检测模块， 用于对各无线网络的网络速率进行检测；
这里， 在得到相关链路的链路质量后， 速率检测单元进行进一步地速 率检测， 以得到实际用户网站的响应速度。 换句话说， 速率检测模块依据 链路质量判断单元确定的网络是否可以提供 PS服务的能力， 来确定是否需 要进行相关链路的速率检测。
在实际应用时， 速率检测单元可以采用不同的实现算法， 得到网站的 响应速度， 例如： 针对访问网站， 可以从终端发起获取访问目标网站中一 个根本不存在的图片， 然后在 on Error事件中计算时间。 需要多次测试， 求多次访问的平均值才能准确计算网站反应速度。 这里， 在测试一个网站 时， 有专门的 http命令 "Trace"。 通常， 使用 Socket编成， 防止过高级的 系统的緩沖、 解析等机制对检测结果的偏差， 最后得出网站的响应速率； 另外， 速率检测单元也可以使用下载客户浏览网站的相关内容， 如相 关静态图片、 网站相关的 LOGO等， 通过下载计算出相关的响应时间得到 实际的网站下载速度。
其中， 速率检测模块在访问用户网站的时候， 可以直接进行域名解析 获取 IP地址、或直接在终端上记录网站和 IP地址的对应表， 实现快速的用 户网站地址获取。
通过链路质量判断单元在后台对于用户访问的相关数据业务网站进行 无线链路的链路质量的测定， 速率检测模块主动地进行后台用户访问网站 的地址访问， 并根据访问的消息响应时间来进行比较判定， 得出能提供最 佳服务的无线链路通道。
在检测速率时， 速率检测模块的内置速率计算脚本检测各个网络所能 提供的下载速率， 选择能提供最佳下载速率的网络作为当前用户下载的承 载网络， 进行数据下载， 随着用户移动， 持续检测合适的高速链路并转换 承载网络， 从而确保用户能够快速切换到合适的网络连接上， 来自适应获 得最佳速率的效果。
速率检测模块需要根据链路质量判断单元检测到的各个网络的链路质 量， 计算相关链路的速率， 通过速率检测模块的自适应计算过程， 最终选 择一个能提供最快速的下载速率的网络， 作为移动终端进行下载服务的承 载网络， 从而实现用户获得最佳下载速率的功能。
链路切换裁定单元， 用于依据检测到的各无线网络的网络速率， 自适 应地将移动终端进行无线数据服务的链路切换至最佳链路上；
具体地， 链路切换裁定单元使用链路质量检测算法， 来实现对于相关 链路质量的接入质量裁定， 并切换到最佳的链路上。
链路质量判断单元和速率检测模块在进行链路质量和速率的判定中， 为了防止频繁链路切换造成实际链路质量的判定失误， 在后台链路检测时 可以设定定时器、 或由用户设定切换的时间周期。 当用户移动到一个新的目标区域后， 移动终端的网络检测模块与速率 检测模块实时在后台进行扫描， 当检测到当前区域中为用户提供服务的网 络消失、 或速率不是最佳时， 终端自动切换到能提供更高速率的合适的网 络链路上， 从而保持用户一直能够享用高的下载速率。
图 2为本发明实施例移动终端自适应提升下载速率的方法流程示意图， 如图 2所示， 该方法包括如下步驟：
S201: 终端开机；
这里， 移动终端开机后， 移动终端初始化完成， 移动终端内置的网络 检测模块开始在后台进行无线网络的建立。
S202: 网络检测模块检测周围的无线网络；
这里， 网络检测模块主动搜索合适的可用的网络， 并进行网络连接建 立。 网络检测模块用于对于移动终端网络周围的无线信号进行检测。 在终 端开机运行后， 网络检测模块完成相关初始化工作就置于后台进行运行。
随着移动终端的移动， 周围的网络信号随时变化， 网络检测模块检测 周围网络信号， 并建立起与各个网络的无线连接，对于具有 UMA功能的移 动终端，本身可以支持各种功能形式的无线网络接入功能，如 Wi-Fi接入功 能， 3G无线、 2G无线、 或 WLAN等等， 移动终端通过相关接入单元与各 个网络之间进行信令交互， 建立起相关的无线网络连接。
S203: 判断是否有合适的无线网络， 如有， 则转入步驟 S204, 否则， 转入步驟 S202继续检测；
网络检测模块可以依据用户的设定或自主根据用户是否进行数据业务 的请求来进行网络能力的判定， 网络检测模块具有识别不同网络特性的能 力。
为对检测到的无线网络进行是否可以提供正常连接进行快速判断， 移 动终端可以依据搜索到的不同的网络特性进行处理， 例如： 当检测到的当 前可以使用的无线网络不具备 PS服务的能力， 网络检测模块可以直接忽略 该网络， 从而实现搜索的高效。
S204: 判断用户是否需要进行数据服务， 如果是， 则转入步驟 S205, 否则， 转入步驟 S202;
具体地， 移动终端的用户业务检测单元判定当前用户是否需要进行数 据服务。
在移动终端上设计一个用户业务检测单元， 用户业务检测单元可以判 定用户是否需要进行数据服务， 若用户需要进行数据服务， 则相关单元需 要检测出相关请求。
用户业务检测单元可以通过检测用户终端应用中的数据服务是否开启 即可实现相关操作的判定， 比如： 检测是否有 http请求或者 SCOKET类相 关操作信息来判定。
S205: 移动终端的链路质量判断单元检测各无线网络的链路质量， 并 由移动终端的速率检测模块对各无线网络的网络速率进行检测；
这里， 链路质量判断单元在用户开启相关数据服务业务后， 开始检测 相关链路的链路质量。 具体地， 在用户开始特定网站数据下载时， 链路质 量判断单元开始检测并判断当前网络的链路质量。
链路质量判断单元可以通过对移动终端周围不同网络的无线链路进行 判断， 来检测相关链路的链路质量， 链路质量包括： 链路是否可用、 是否 可以进行有效的连接建立响应、 或是否可以进行相关的数据服务。
链路质量判断单元在检测各个网络的链路质量时， 可以通过发送相关 PING指令到特定网站地址， 并根据包的响应延迟来确定当前不同网络的链 路质量。 其中， Ping 指令作为一个常用的网络测试指令， 可以用来对于链 路质量和相关网站进行简单的测试工作， 当使用不同的相关指令参数时， 可以获得不同的响应信息， 如 TTL时间、 ECO时间、 以及通过发送不同的 包得到相关的反馈时间后计算出链路的速度。
其中， 链路质量判断单元在判断链路是否可以提供数据服务能力时， 可以通过与无线网络交互的信令消息来进行判定。
在得到链路的链路质量后， 速率检测单元可以进行进一步的速率检测， 以得到实际用户网站的响应速度。 换句话说， 速率检测模块依据链路质量 判断单元确定的网络是否可以提供 PS服务的能力， 来确定是否需要进行相 关链路的速率检测。
在实际应用时， 速率检测单元可以采用不同的实现算法， 得到网站的 响应速度， 例如： 针对访问网站， 可以从终端发起获取访问目标网站中一 个根本不存在的图片， 然后在 on Error事件中计算时间。 需要多次测试求 多次访问的平均值才能准确计算网站反应速度。 这里， 在测试一个网站时， 有专门的 http命令 "Trace"。 通常， 使用 Socket编成， 防止过高级的系统 的緩沖、 解析等机制对检测结果的偏差， 最后得出网站的响应速率；
另外， 速率检测单元也可以使用下载客户浏览网站的相关内容， 如相 关静态图片、 网站相关的 LOGO等， 通过下载计算出相关的响应时间得到 实际的网站下载速度。
其中， 速率检测模块在访问用户网站的时候， 可以直接进行域名解析 获取 IP地址或者直接在终端上记录网站和 IP地址的对应表，实现快速的用 户网站地址获取。
通过链路质量判断单元在后台对于用户访问的相关数据业务网站进行 无线链路质量的测定， 速率检测模块主动地进行后台用户访问网站的地址 访问， 并根据访问的消息响应时间来进行比较判定， 得出能提供最佳服务 的无线链路通道。
链路质量判断单元和速率检测模块在进行链路质量和速率的判定中， 为了防止频繁链路切换造成实际链路质量的判定失误， 在后台链路检测时 可以设定定时器、 或由用户设定切换的时间周期。
S206: 选择一个最佳无线网络链路；
这里， 链路切换裁定单元获得当前移动终端所处位置的最佳速率接入 网络后， 链路切换裁定单元提示用户手动、 或自动把该链路作为当前用户 进行数据服务的首选链路。
链路切换裁定单元将终端当前进行数据服务的链路切换到最佳速率接 入网络的无线网络链路上， 链路切换裁定单元在进行链路的切换时， 可以 根据当前选择的网络状态和终端实际注册的网络状态进行比较判断， 可以 把移动终端当前注册的网络直接切换到该条无线链路的网络上， 也可以根 据当前网络的实际选择共存的方式， 如当终端注册到 3G 网络， 但周围的 Wi-Fi网络提供的无线链路质量比较好， 无线终端可以依旧驻留在 3G网络 上但用户进行数据下载服务的网络可以切换为 Wi-Fi。
S207: 判断链路是否建立成功， 如果成功， 则转入步驟 S208, 否则， 转入步驟 S206;
S208: 移动终端使用该链路为用户提供数据服务， 并转入步驟 S202继 续检测。
当用户移动到一个新的目标区域后， 移动终端的网络检测模块与速率 检测模块实时在后台进行扫描， 当检测到当前区域中为用户提供服务的网 络消失或者速率不是最佳， 则终端自动切换到能提供更高速率的合适的网 络链路上， 从而保持用户一直能够享用高的下载速率。
为了防止频繁切换造成的链路持续切换， 网络检测模块和速率检测模 块可以在后台周期运行， 检测周期也可以逐步加大。
请参考图 3 所示， 是本发明实施例移动终端的速率检测模块工作流程 示意图， 其包括如下步驟：
S301 : 移动终端的速率检测模块启动； S302: 获得当前所注册网络的链路质量；
S303: 判断是否获得最佳链路， 如果是， 转入步驟 S305 , 否则， 转入 步驟 S304;
S304: 后台继续跟踪检测相关链路；
S305: 切换到最佳链路网络获取数据服务。
使用本发明技术方案， 用户无须人为进行网络连接的干预， 移动终端 将依据内嵌的脚本程序来进行相关网络的检测， 主动获取各个网络下的下 载速率 , 进行择优判断来选择一个最佳速率链路来提升用户对于高速无线 带宽享受。
当然， 本发明还可有多种实施方式， 在不背离本发明精神及其实质的 情况， 熟悉本领域的技术人员当然可根据本发明做出各种相应的更改或变 化， 但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， 均应包含在本发明的保护范围之内。
