Description

一种切换网络的终端、方法及系统 技术领域
本文涉及一种处理网络制式的终端、方法及系统，尤其涉及一种切换网络的终端、方法及系统。
背景技术
随着无线网络及通讯技术的发展，移动终端的主要功能不仅仅是通话，数据业务已经成为移动终端的重要功能之一。移动终端进行数据业务的方式主要有两种，一种为采用终端本身运营商移动网络，例如通过第二代移动通信技术(2G)，第三代移动通信技术(3G)以及第四代移动通信技术(4G)(如Long term evolution，以下简称LTE)等制式使用网络，另一种是使用无线保真(WirelessFidelity，WI-FI)网络。
在不同的网络下进行数据业务的速率不尽相同，如2G理论速率为每秒384K，3G理论速率最高为每秒21M，而LTE网络在不同带宽下理论速率不同，包括每秒37M、75M、150M及300M等。在WI-FI网络下，不同的协议标准的数据业务的速率也大不相同，如当前主流的802.11b为每秒11M，802.11g为每秒54M，802.11n可达到每秒350M，而802.11ac更可达到每秒1G。
网络的协议、带宽或负载情况等因素，都会对网络的速率产生影响。用户在使用WI-FI网络或运营商网络时，只能感知具体的业务形式，无法根据当前网络的实际速率选择速率大的网络进行数据业务。对于具体网络的选择，相关技术的实现方式为用户人为选择网络，若用户想使用WI-FI则开启终端上的WI-FI功能，若用户想使用运营商网络则关闭WI-FI功能开启数据功能，采用这种方式，用户在真正使用网络时无法准确选择更优的网络，此外，目前在终端上当WI-FI及运营商网络同时开启时，默认优先接入WI-FI网络，给用户造成不便，不能有效提升用户体验。

本发明的实施方式
如图1所示，为本发明切换网络系统10实施例的运行环境图。所述切换网络系统10运行在终端1上，所述终端包括存储器11和处理器12，所述处理器12设置为控制所述切换网络系统10进行切换网络操作。
如图2所示，是本发明切换网络系统10的实施例的功能模块图。该切换网络系统10包括一个或多个模块，所述一个或多个模块存储于所述存储器11中。本实施例中，所述切换网络系统10包括网络信息获取模块100、理想速率评估模块101、网络选择模块102、及网络切换模块103。
所述网络信息获取模块100设置为获取多个当前网络的网络参数，并将所述获取的网络参数存储于所述存储器11中。所述多个当前网络包括运营商网络和WI-FI网络。所述网络参数包括网络的协议版本、网络的带宽、网络的信号强度等，例如WI-FI网络的网络参数包括网络的协议版本(802.11b、802.11g、802.11n、802.11ac等)、WI-FI的信号强度等，LTE网络的网络参数包括LTE终端本身的支持能力，如category、LTE网络的Band、带宽、信号强度等信息。所述网络信息获取模块100为周期性地获取当前网络的网络参数，例如每5分钟或每10分钟获取一次当前网络的网络参数，以实时监测当前网络是否发生变化，并将实时的网络参数存储于所述存储器11中。
所述网络信息获取模块100获取当前网络的网络参数的流程如图3所示，包括：
S30，周期性地获取当前网络的网络参数；
S31，存储获取到的所述网络参数。
由于当前网络在传输的过程中有所损耗，所述理想速率评估模块101设置为对所述网络信息获取模块100获取到的所述网络参数进行评估计算，得出所述多个当前网络的理想速率，并将得到的所述当前网络的理想速率存储于所述存储器11中。例如当终端1为cat3终端，LTE网络带宽为20M，信号强度大于-80dBm(理想强度)时，当前LTE网络的理想速率为100Mbps。所述理想速率评估模块101根据当前LTE网络的损耗将该LTE网络当前的理想速率评估为90Mbps。又例如当WI-FI网络协议版本为802.11g，信号强度为优时，理想速率为54Mbps，所述理想速率评估模块101将该WI-FI网络的理想速率评估为48Mbps。
所述网络选择模块102设置为在所述终端1进行数据业务前，比如用户打开手机上的网络浏览器、微博、微信或QQ等应用程序时，所述网络选择模块102判断用户开始准备进行数据业务，所述网络选择模块102将当前环境中存在的所述多个当前网络的理想速率进行比较，确定理想速率最大的当前网络E1，所述网络选择模块102接入理想速率最大的当前网络E1进行数据业务。例如当前LTE网络的理想速率为90Mbps，当前WI-FI网络的理想速率为48Mbps，则所述网络选择模块102选择接入所述当前LTE网络进行数据业务。
所述网络选择模块102在所述终端1选择网络的流程如图4所示，包括：
S40，终端准备进行数据业务；
S41，终端获取当前网络的网络参数；
S42，评估当前网络的理想速率；
S43，判断当前网络中的第一网络的理想速率是否大于第二网络的理想速率，若是，则执行S45，若否，则执行S44；
S44，使用第一网络，流程结束。
S45，使用第二网络，流程结束。
图4中第一网络和第二网络代表当前终端1所处的环境中存在的两个网络。
所述网络切换模块103设置为将所述终端1切换到一个实际速率最大的当前网络进行数据业务。所述当前网络在所述终端1中有一个计时器T，所述计时器T的初始值为零，当所述终端1从所述当前网络切换到另一个新的当前网络时，所切换到的新的当前网络对应的计时器T开始计时，计时到一定时间t后，所述计时器T清零。例如，所述终端1从LTE网络切换到WI-FI网络，则WI-FI网络对应的计时器T开始计时，当该计时器计时到一定时间t(如20分钟)后，该计时器T的值清零。
其中，将所述终端1切换网络进行数据业务可以包括以下几个步骤：
第一判断步骤，将所述终端1接入的当前网络E1的实际速率V1与该当前网络E1的理想速率L1进行比较，若V1小于α×L1，则执行第二判断步骤。若V1不小于α×L1，则所述终端仍接入该当前网络E1进行数据业务0＜α≤1。
第二判断步骤，判断所述终端1是否刚进行过网络的切换，即距离上一次网络切换的时间是否小于一阈值，如果所述终端1刚进行过网络的切换，则执行第一判断步骤。如果所述终端1不是刚进行过网络的切换，则进行第三判断步骤。本实施例中，所述判断所述终端1是否刚进行过网络切换是利用所述计时器T来完成的，当所述计时器T的值为零时，说明距离上一次切换网络已经有一段时间了，所述终端1可以再进行网络切换；当所述计时器的值不为零时，说明所述终端1刚进行过网络切换。
第三判断步骤，判断所述V1是否小于所述终端1未接入的当前网络E2的理想速率L2。若所述V1小于所述L2，则将所述终端切换到所述E2，若所述V1不小于所述L2，则执行第一判断步骤。
第四判断步骤，判断所述终端1未接入的当前网络E2的实际速率V2是否大于等于所述V1，若所述V2大于等于所述V1，则所述终端1选择所述E2进行数据业务，并将所述E1加入黑名单，一定时间t内不会再切换，此时所述E2成为所述终端1的当前接入网络。若所述V2小于所述V1，则所述终端1仍选择所述E1进行数据业务，并将所述E2加入黑名单，一定时间t内不会再切换，所述E1仍为当前接入网络。本实施例中，所述一定时间t可以设置为20分钟、30分钟或40分钟等，利用计时器T进行计时，当所述计 时器T计时到一定值t时，清零，直到下次切换动作完成后启动计时。设置一定时间内不会再切换的目的是为了避免所述终端1在网络之间频繁切换引起乒乓效应。
如图5所示，为本发明切换网络的方法的实施例的流程图。
S50，所述终端1在接入的当前网络E1下进行数据业务。
S51，将所述终端1接入的当前网络E1的实际速率V1与该当前网络E1的理想速率L1进行比较，若V1小于α×L1，则执行S52，若V1不小于α×L1，则所述终端仍接入该当前网络E1进行数据业务，0＜α≤1。
S52，判断距离所述终端1是上一次切换的时间是否小于一阈值，如果小于阈值，则执行S51；如果大于等于阈值，则进行S53。所述判断所述终端1是否刚进行过网络切换是利用所述计时器T来完成的，当所述计时器T的值为零时，说明距离上一次切换网络已经有一段时间了，所述终端1可以再进行网络切换；当所述计时器的值不为零时，说明所述终端1刚进行过网络切换，所述终端1还不能再次进行网络切换。
S53，判断所述V1是否小于终端1未接入的当前网络E2的理想速率L2，若所述V1小于所述L2，则执行S54，若所述V1不小于所述L2，则执行S51。
S54，所述终端1切换到所述E2。
S55，判断所述当前网络E2的实际速率V2是否大于等于所述V1，若所述V2大于等于所述V1，则执行S56；若所述V2小于所述V1，则执行S57。
S56，所述终端1选择所述E2进行数据业务，并将所述E1加入黑名单，一定时间t内不会再切换，此时所述E2成为所述终端1的接入网络。
S57，若所述V2小于所述V1，则所述终端1仍选择所述E1进行数据业务，并将所述E2加入黑名单，一定时间t内不会再切换，所述E1仍为接入网络。所述一定时间t可以设置为20分钟、30分钟或40分钟等，利用计时器T进行计时，当所述计时器T计时到一定值t时，清零，直到下次切换动作完成后启动计时。设置一定时间内不会再切换的目的是为了避免所述终端1在网络之间频繁切换引起乒乓效应。
