The typical types of applications that need WAPProtocolStack functionality today includeReceivingpayable content and MMS messaging. Below thebasicreasonsareexplained.
RECEIVING PAYABLE CONTENT
TheAndroidWEBBrowseruses theHTTPprotocolto connectdirectly to webservers to retrieve content. This is the defaulttransportusedbytheAndroidbrowser.Usingthisprotocolwillnot
allowthedownloadofpayablecontentpushedtoadeviceusingWAPPush.
Acting as a WAP Browser when required: TheAndroid devicecan act as aWAP Browser for content download whenusingWinwaps WAP 1.2 or WAP 2.0 stack to connect to a WAPGateway/Proxy.Asthe requestpassestheWAPGateway/Proxythecarriercantrackitandmakesurecustomershavereceivedtheir bil lable content (different carriers may use differentmethods).Ifthecontentisaweb/wappage,theWAPStackcanforwardittotheAndroidbrowserfordisplaying.
MULTIMEDIA MESSAGING
Multimedia Messaging (MMS) usesWAPProtocolStack (WAP
1.2 or WAP 2.0) for message delivery. Winwap provides
separatelyfromtheWAPStackSDK,a full MMS S K withpowerful API both on NDK and JNI) for MMS functionality.
When aMMSMessage issent toaGSM/CDMArecipient, theGSM/CDMAdeviceactually receives a SMSmessage inWAPPush format. ThisWAP Push message includes a NotificationthatanewMMSmessageexists.Then,thedevicemustopenadataconnectionusingaspecificAPNand use theWAP 1.2 orWAP2.0protocoltodownloadtheactualMMSMessagefromtheMMSC (MMS Center). When sending MMS messages the theGSM/CDMAdevicealso usesWAP 1.2 orWAP 2.0 andWAP
Gateway/ProxytodeliverthemessagetothecarriersMMSC.
SUMMARY
The WAP Protocol Stack is an important part of all modernhandsets.DeliveryofpaidcontentusesWAPconnectionsasthisway the carrierscan charge for the content on the consumersmonthly invoice (or subtract from pre-paid accounts). WithoutWAP, the carrier can not control the delivery and billing forpayablecontent,andcreditcardsorothermeansmustbeuseforbillingpurposesinconjuctionwithOMADownloadprotocols(alsoavailable fromWinwapTechnologies). If users buy a ringtone,java application or similar by sending a sms to some contentprovider,theirGSM/CDMAdevicetypicallyreceivesaWAPPush
