Wireless Session Protocol
Encyclopedia
Wireless Session Protocol (WSP) is an open standard
for maintaining high level session. Wireless session is nothing but a normal Web browsing
session that starts when the user connects to one URL and ends when the user leaves that URL. By establishing the session means that the session wide properties need only to be defined once at the beginning of the session. This has the benefit of saving bandwidth due to the nature of the wireless communication. The session establishing process will not have lengthy hand shaking mechanisms.
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 datagram transport service. Therefore, WSP exists for two reasons. First, in the connection-mode it enhances the HTTP 1.1's performance over wireless environment. Second, it provides a session layer
so the whole WAP environment resembles ISO OSI Reference Model

The session layer is layer 5 of the seven-layer OSI model of computer networking.The session layer provides the mechanism for opening, closing and managing a session between end-user application processes, i.e., a semi-permanent dialogue. Communication sessions consist of requests and responses...
