default、mms、supl、dun、hipri接入点类型的区别
设置APN上网时，大家可能经常遇到这个问题：
为什么有时要填写default有时要填写supl，而彩信又偏偏要mms？
这个问题留到最后，让我们看看每个接入点类型的含义：
英文原文来自于Google Android Developers
原文连接:/reference/android/net/
我尽量用通俗易懂的语言来解释每个类型的含义，若您是开发者，请尽量阅读英文原文。
1、default
默认网络连接，当激活时所有数据传输都使用该连接，不能与其他网络连接同时使用
View Code JAVA
[java] view plaincopyprint?
1. /**
2. * The Default Mobile data connection. When active, all data traffic
3. * will use this connection by default. Should not coexist with other
4. * default connections.
5. */

TYPE_MOBILE = 1

4. * default connections.
5. */
6. public style="COLOR: #000000; FONT-WEIGHT: bold">static style="COLOR: #cc66cc">0
适用场合：绝大部分正常上网时可以使用
2、mms
彩信专用连接，此连接与default类似，用于与载体的多媒体信息服务器对话的应用程序，此连接能与default连接同时使用
View Code JAVA
[java] view plaincopyprint?
1. /**
2. * An MMS-specific Mobile data connection. This connection may be the
3. * same as TYPE_MOBILE but it may be different. This is used
4. * by applications needing to talk to the carrier's Multimedia Messaging
5. * Service servers. It may coexist with default data connections.

6. */
7. public style="COLOR: #000000; FONT-WEIGHT: bold">static
2;
适用场合：使用彩信服务时，必须有mms类型的接入点，不必选中，应用程序会自动使用此接入点
3、supl
是Secure User Plane Location“安全用户面定位”的简写，此连接与default类似，用于帮助定位设备与载体的安全用户面定位服务器对话的应用程序，此连接能与default连接同时使用

适用场合:需要自动切换wap与net接入点的、需要把手机当临时AP的

4、dun
Dial Up Networking拨号网络的简称，此连接与default连接类似，用于执行一个拨号网络网桥，使载体能知道拨号网络流量的应用程序，此连接能与default连接同时使用

适用场合：需要使用运营商无线热点的，CMCC、ChinaNet等
5、hipri
高优先级网络，与default类似，但路由设置不同。
只有当进程访问移动DNS服务器，并明确要求使用requestRouteToHost(int, int)才会使用此连接
（这个我也不太懂，翻译的应该很有问题….）

好了，最后教给大家一个一劳永逸的APN设置大法：2个接入点搞定一切
以下内容分运营商的地方我会标注出来，默认以中国联通3G为例
1、NET接入点
接入点名称任意
APN：3gnet(移动2g:cmnet 联通2g:uninet)
接入点类型:default,supl,dun
其他都为空
2、WAP接入点
APN:3gwap(移动2g:cmwap 联通2g:uniwap)
代理:10.0.0.172
端口:80
mmsc:(此项不区分2G3G，移动:)
彩信代理:10.0.0.172
彩信端口:80
APN类型:default,mms
