The Design And Realization Of Wireless Terminal OTA Setting Based On WAP

OTA(Over-the-Air) technology: The network operations merchant can transport data to terminals and long-distance sites by using OTA technology.WAP(Wireless Application Protocol) is standard communication Protocol of mobile internet application paragram. Its main goal is to supply an optimized open standard with mobile device surfing on the web or Internet.Although STK technology has solved the problem of the use and realization of the incremental services when it just appeared, because OTA customers can't conveniently modify the menus in the SIM card, STK technology can't be popularized. Commercial STK cards open a good scene really until the appearance of Over the Air Technology. Mobile user can get the services easily by OTA technology everywhere ande verytime, for example: increase applications ,modify applications,alert applications and delete applications without changing any firmwares. WAP OTA set up WAP homepage, web parameters,bookmark by Short Message Service.The paper emphasizes the design and realization of WAP OTA setting of the wireless terminal which is at the platform of Philips GSM Dragonfly at the base of the related theories and protocol and the key techniques of WAP OTA.WAP OTA Setting is realized by Short Message Service. OTA criterions is used to pack WAP parameters in a given format to a SMS that arrives the WAP terminal through GSM channel. The terminal decodes the SMS by XML decoder then the decoded parameters and its values are distributed to EEPROM. We can find the according setting parameters in the mobile after my code dealed with them. The user confirm them and can go into web or Internet. If the mobile terminal supports the WAP OTA ,it changes the special SMS into WAP setting parameters after confirming the SMS. So it is easy way to set up WAP setting parameters.
