Wireless Session Protocol

The Wireless Session Protocol (WSP) is a communication protocol used in wireless networks to establish and manage sessions between a client and a server. It is part of the Wireless Application Protocol (WAP) suite of protocols and is designed to provide reliable and efficient data transfer over wireless connections. WSP allows for the exchange of messages between the client and server, enabling the delivery of content such as web pages, emails, and other data.

Wireless Session Protocol (WSP) is an open standard[1] for maintaining high-level Wireless sessions. The Protocol is involved from the second that the user connects to one URL and ends when the user leaves that URL. The session-wide properties are defined once at the beginning of the session, saving bandwidth over continuous monitoring. The session-establishing process does not have long connection algorithms.

WSP is based on HTTP 1.1 with few enhancements. WSP provides the upper-level application layer of WAP with a consistent interface for two session services. The first is a connection-oriented service that operates above a transaction layer protocol WTP and the second is a connectionless service that operates above a secure or non-secure data-gram transport service. Therefore, WSP exists for two reasons. First, the connection mode enhances HTTP 1.1's performance over the wireless environment. Second, it provides a session layer so the whole WAP environment resembles OSI OSI Reference Model.
