Editor's Notes
- (WDP) represents transport layer that send and receive message via network. (WTLS) that does the encryption and provides security transport services required by many applications. (WSP) layer that provides efficient exchange of data between applications.
- Wireless Profiled HTTP (WP-HTTP) – WP-HTTP specification is a profile of HTTP for the wireless environment and is fully interoperable with HTTP/1.1. The basic model of interaction between the WAP Device and WAP Proxy/WAP Server is the HTTP request/response transaction. WP-HTTP supports message body compression of responses and the establishment of secure tunnels. Transport Layer Security (TLS) – A wireless profile of the TLS protocol will permit interoperability for secure transactions. This profile for TLS includes cipher suites, certificate formats, signing algorithms and the use of session resume. The profile also defines the method for TLS tunneling to support end-to-end security at the transport level. Wireless Profiled TCP (WP-TCP) – WP-TCP provides connection-oriented services. It is optimized for wireless environments and is fully interoperable with standard TCP implementations in the Internet. Research in optimizing TCP has resulted in a number of mechanisms to improve performance. This includes work by the IETF PILC group that has recommended the use of some of these mechanisms for TCP implementations in long thin networks. These have been documented in Standards Track RFCs and have been accepted by the Internet community as useful and technically stable.
- WAP Push - This service allows content to be sent or &quot;pushed&quot; to devices by server-based applications via a Push Proxy. This functionality has been enhanced for the WAP 2.0 release. Push functionality is especially relevant to real-time applications that send notifications to their users, such as messaging, stock price and traffic update alerts. Without push functionality, these types of applications would require the devices to poll application servers for new information or status. User Agent Profile (UAProf) – This service provides a mechanism for describing the capabilities of clients and the preferences of users to an application server. Enhanced for WAP 2.0 release, it is based on the Composite Capabilities / Preference Profiles (CC/PP) work of the W3C, UAProf supports the client-server transaction model by sending client and user information to servers with the request. This information permits the servers to adapt their content accordingly in preparation for the response. Recognizing the importance of user&apos;s privacy, personal information submitted in these requests may be controlled by the user. WTA This service provides tools that provide for a range of advanced telephony applications to be operated from within the application environment that traditionally supports data functionality. These call handling services, such as making calls, answering them, placing them on hold and redirecting them, can be seamlessly combined with other data services. This truly permits WAP WTA enabled cell phones to be viewed as fully integrated Internet and voice service platforms. MMS This service provides the framework to implement a feature-rich messaging solution. MMS provides features and functionality that permits delivery of varied types of content. Depending on the service model, MMS permits a quick delivery paradigm (like SMS) or a store-and-forward approach (like email) or could permit both modes to operate.
