WAP is the Wireless Application Protocol [Wireless Communication Agreement].
Provides the global unified open protocol standard for Internet content services and value-added services to mobile terminals, which can be said to be a simplified wireless Internet protocol.
WAP Network Architecture: WAP Gateway WAP Mobile WAP Content Server.
The WAP protocol includes the following layers:
1.wireless application enviroment [wae]
2.wireless session layer [WSL]
3.wireless Transport Layer Security [WTLS]
4.Wireless Transport Layer [WTP]
WAE contains a function of micro browser, WML, WMLScript interpreter.
The WTLS layer provides security for wireless e-commerce and wireless encrypted transmission data.
On the Internet, the company has looked at some of the previous documents to understand that WAP began to rise in N years. [I thought it was only trendy in this two years, but n <10. ].
And and sum, it should be a "large company in 1997 in order to promote the promotion of wireless network applications. In 1999, there was a practical development platform. The previous industry expects WAP market growth will be very fast. China Mobile and China Unicom are also more optimistic about this market. But it seems that in 2002, the market is relatively good, maybe it is the reason for the network, perhaps the reason for the terminal, perhaps the reason for operating habits, anyway, the WAP market is more dead.
Now, China Unicom's CDMA network should be done, China Mobile's grabbed market for users and hopes to develop this market, so it is estimated that it can not make money, can earn more money, Do this. [In fact, I think this thing can still earn money. . So I didn't divide the spans who didn't divide the WAP, I followed it.
WAP compares text messages should still have its partial advantage - capacity, and harness, and others.
WAP's language standard is WML, which can be written using PHP, JSP, ASP, and E even C. Although I used JSP before, this time I develop WAP estimated to use PHP, because the server has been built as PHP and develops a lot of columns. To migrate, you have to come slowly. ] It has a WMLScript scripting language similar to web programming. Its server environment can be built with IIS or APACH.
Well, these are my basic understanding, I don't know if the deviation is large.
Next, it is understood that the configuration of some servers, learning the WAP protocol specification, WML standard, Wmlscript language, and php [cold, studying languages, and, JSP / Java can't lose, write two Java C / s program, practice hands].
And and, or column 1, 2, 3, 4.
1. Server configuration 2.WAP protocol specification 3. WML standard [language? ] 4.Wmlscript language 5.php
OVER, the next chapter continues.
[kao, look at people's articles, write some next, "said it will not move. ]
