一、基本信息 标题:WEB页面的移动终端适配技术研究 时间:2012 来源:北京邮电大学 关键词:移动互联网;适配系统;插件系统结构;系统管理 二、研究内容 第一章绪论 1. 在全业务运营时代,用户对移动终端的需求已经逐渐从基木的语音业务向更丰富的综合服务转变,中国电信适时提出了互联网终端的概念,使传统通信业务逐渐与移动互联网业务相融合”。随着移动通信及3G的不断普及,移动互联网的用户数量正在急剧增加,PC 端的业务在移动终端适配的研究随着开展起来。现在互联网上的许多应用都可以移植到将来的手机上,未来的手机将会是多媒体的终端。而用于机浏览互联网的内容无疑是重要的应用之- -,3G在于机用户中的认可度也迅速提升。根据CNNIC的调查。约3.47亿的手机用户知道有3G业务,大概占手机用户的64.5%;有计划要使用3G手机上网的手机用户大概有4000万,占总人数的23.1%。这个结果证明,手机用户对3G市场的需求量很大,认可度也很高。3G 牌照的发放势必会催生使用3G上网的用户数量的增加。 由于市场潜力的巨大以及竞争的激烈。用智能手机等移动设备访间互联网的用户已越来越多,但日前,用户使用习惯普遍是使用手机自带的浏览器,高级用户则使用多浏览器搭配。另-方面,目前用户对于互联网的使用除了浏览器外,大多是使用各种专属的应用程序鬥。目前,手机自带浏览器仍占据一半的移动互联网用户市场。CNNIC的

Switching from WiFi connection to 3g causes connection to hang?

I have an application which connects to a web service. I can connect to the web service any number of times without any problem using WIFI or 3G provided that I stay loyal to my connection type during the life cycle of my application. That is if I don't switch from WIFI to 3G. If I switches from WIFI to 3G, I can't get a response anymore. My connection just keeps on waiting for response. I tried 4 scenarios below. I'm only having problem with the 3rd scenario. What could be the problem? 1st Scenario: Connection is always on WIFI (Ok) Application connects to a web service using WIFI. Response

Iphone 3g browser rendering problems. Wifi is fine

拥有回忆 提交于 2019-12-05 21:03:43
I'm building a site which seems to work fine on all web browsers except the iPhone on a 3G network. For some reason it is not being displayed correctly as if the CSS is not being parsed. As part of my investigation, I've tried the same browser (iPhone Safari) in a wifi connection and the page renders fine. The page is written in classic ASP, what is interesting is that if I copy the rendered source from a PC browser and give it an extension of .htm, when you view this on the iPhone on 3G it renders fine. Same code, so is this something odd with classic ASP and 3G or possibly the mobile

Why does the native SIP stack included in Android 2.3 does not work over 3g?

三世轮回 提交于 2019-12-05 11:04:50
I was wondering why does the native SIP stack included in the Android framework(since 2.3) does not work over 3g? Could it have something to do with any laws or restrictions google may have with his partners? And furthermore, does anybody know if there is any plans to remove that restriction ? Thx In GingerBread , SipManager is set to work only on wifi. `<bool name="config_sip_wifi_only">true</bool>` But from 4.0 onwards , this config has been changed to false So Ideally native sip stack should work on 3G from Ice Cream Sandwich onwards. But again if the phone is sold by a service provider,

I'm writing a travel guide related app that will download large databases (60meg) potentially overseas, with the reachability code I can tell when a host is reachable via wifi or 3g BUT I'm worried that if for some reason the wifi connection breaks for a minute or so as some DSL connections are likely to do on occasion the iphone will switch transparently to 3G and without realising I could be racking up someones phone bill with overseas data charges! So I'm wondering if anyone has any experience, in the event of such break in wifi connectivity (wifi still works but it's connection to the net

Android: How to check whether 3G is enabled or not?

此生再无相见时 提交于 2019-12-04 18:29:10
I need to know whether 3G connectivity is permitted on the device or not. I don't want to know what current network state is, because if you set "Network Mode" setting in "Mobile network settings" screen to "Automatic" network state could be either 2G or 3G. I just want to know which setting is selected there - 2G, 3G or Automatic (latter two mean the same for me). Both telephonyManager.getNetworkType() and ConnectivityManage.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).getState() are returning current network state, which can lead me in a wrong direction, because if current state is 2G it
