中国移动net,wap接入点的名称类型default、mms、supl、dun、hipri的区别.doc

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/ConnectivityManager.html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 JAVA123456java 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. */ 6. public static final int TYPE_MOBILE = 0; 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. */ 6. public static final int TYPE_MOBILE = 0; /* * The Default Mobile data connection. When active, all data traffic * will use this connection by default. Should not coexist with other * default connections. */ public static final int TYPE_MOBILE = 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 JAVA1234567java 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 carriers Multimedia Messaging 5. * Service servers. It may coexist with default data connections. 6. */ 7. public static final int TYPE_MOBILE_MMS = 2; 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 carriers Multimedia Messaging 5. * Service servers.

This connection may be the * same as TYPE_MOBILE but it may be different. This is used * by applications needing to talk to the carriers Multimedia Messaging * Service servers. It may coexist with default data connections. */ public static final int TYPE_MOBILE_MMS = 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View Code JAVA123456789java view plaincopyprint?1. /* 2. * A SUPL-specific Mobile data connection. This connection may be the 3. * same as link #TYPEMOBILE but it may be different. This is used 4. * by applications needing to talk to the carriers Secure User Plane 5. * Location servers for help locating the device. It may coexist with 6. * default data connections. 7. * hide 8. */ 9. public static final int TYPE_MOBILE_SUPL = 3; java view plaincopyprint?1. /* 2. * A SUPL-specific Mobile data connection. This connection may be the 3. * same as link #TYPEMOBILE but it may be different. This is used 4. * by applications needing to talk to the carriers Secure User Plane 5. * Location servers for help locating the device. It may coexist with 6. * default data connections. 7. * hide 8. */ 9. public static final int TYPE_MOBILE_SUPL = 3; /* * A SUPL-specific Mobile data connection. This connection may be the * same as link #TYPEMOBILE but it may be different. This is used * by applications needing to talk to the carriers Secure User Plane * Location servers for help locating the device. It may coexist with * default data connections. * hide */ public static final int TYPE_MOBILE_SUPL = 3;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的对SUPL技术感兴趣的朋友，不妨看下以下文章SUPL技术(一)/s/blog_537f4a11010008tw.htmlSUPL技术(二)/s/blog_537f4a11010008uf.htmlSUPL技术(三)/s/blog_537f4a11010008ws.htmlSUPL技术(四)/s/blog_537f4a11010008yf.html4、dunDial 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View Code JAVA12345678java view plaincopyprint?1. /* 2. * A DUN-specific Mobile data connection. This connection may be the 3. * same as link #TYPEMOBILE but it may be different. This is used 4. * by applicaitons performing a Dial Up Networking bridge so that 5. * the carrier is aware of DUN traffic. It may coexist with default data 6. * connections. 7. */ 8. public static final int TYPE_MOBILE_DUN = 4; java view plaincopyprint?1. /* 2. * A DUN-specific Mobile data connection.

It may coexist with default data * connections. */ public static final int TYPE_MOBILE_DUN = 4;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.）View Code JAVA123456789java view plaincopyprint?1. /* 2. * A High Priority Mobile data connection. This connection is typically 3. * the same as link #TYPEMOBILE but the routing setup is different. 4. * Only requesting processes will have access to the Mobile DNS servers 5. * and only IPs explicitly requested via link #requestRouteToHost 6. * will route over this interface. 7. *hide 8. */ 9. public static final int TYPE_MOBILE_HIPRI = 5; java view plaincopyprint?1. /* 2. * A High Priority Mobile data connection.
