The WAP accepted declared a agreement apartment acceptance the interoperability of WAP accessories andcomputer application with altered arrangement technologies, such as GSM and IS-95 (also accepted as CDMA).
The bottom-most agreement in the suite, the WAP Datagram Agreement (WDP), functions as an adjustment band that makes every abstracts arrangement attending a bit like UDP to the high layers by accouterment capricious carriage of abstracts with two 16-bit anchorage numbers (origin and destination). All the high layers appearance WDP as one and the aforementioned protocol, which has several "technical realizations" on top of added "data bearers" such as SMS, USSD, etc. On built-in IP bearers such as GPRS, UMTS packet-radio service, or PPP on top of a circuit-switched abstracts connection, WDP is in actuality absolutely UDP.
WTLS, an alternative layer, provides a public-key cryptography-based aegis apparatus agnate to TLS.
WTP provides transaction abutment (reliable request/response) acclimatized to the wireless world. WTP supports added finer than TCP the botheration of packet loss, which occurs frequently in 2G wireless technologies in best radio conditions, but is misinterpreted by TCP as arrangement congestion.
Finally, one can anticipate of WSP initially as a aeroembolism adaptation of HTTP.
This agreement apartment allows a terminal to address requests that accept an HTTP or HTTPS agnate to a WAP gateway; the aperture translates requests into apparent HTTP.
