1. Scope
Wireless Application Protocol (WAP) is a result of continuous work to define an industry wide specification for developing applications that operate over wireless communication networks. The scope for the WAP Forum is to define a set of specifications to be used by service applications. The wireless market is growing very quickly and reaching new customers and providing new services. To enable operators and manufacturers to meet the challenges in advanced services, differentiation, and fast/flexible service creation, WAP defines a set of protocols in transport, session and application layers. For additional information on the WAP architecture, refer to “Wireless Application Protocol Architecture Specification” [WAP].

4.1 Definitions
The following are terms and conventions used throughout this specification.
The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described by [RFC2119].
Application – A value-added data service provided to a WAP Client. The application may utilise both push and puldata transfer to deliver content
Application-Level Addressing – the ability to address push content between a particular user agent on a WAP clienand push initiator on a server.
Bearer Network – a network used to carry the messages of a transport-layer protocol between physical devices.
Multiple bearer networks may be used over the life of a single push session.

5. Introduction
The architecture consists of a distributed client/server application, with a server residing in the push proxy gateway or a push initiator, and a client residing in the mobile device. The server and client communicate using the Push OTA protocol which utilises WSP Session [WSP] services.
Connection-oriented push requires that a push session is established before the push content can be delivered. The connection-oriented push includes both confirmed and unconfirmed push. A push session for a connection-oriented push can be shared among multiple client applications. Each one of two registered WDP ports for connectionless push can also be shared among multiple client applications. A client application is identified by application ID.
