Answer 1

Answer:

Messaging services are a key component that enhance your applications by supporting sending and receiving messages among mobile users. OracleAS Wireless Messaging services provide a highly scalable mechanism to deliver messages to all mobile devices. Messages are delivered to mobile devices using native device protocols, for example through SMS to a mobile phone, as an e-mail to a 2-way pager, as an audio message to regular telephone, as an Instant Messaging (IM) message to an IM client or as a fax to a fax machine.

Messaging services in OracleAS Wireless also offer a Web Service Interface (specified using WSDL) that uses SOAP over HTTP. The SOAP service enables applications to invoke remote object methods over HTTP protocol. This enables applications to invoke Messaging services from anywhere on the Internet, using any programming model. OracleAS Wireless Messaging services enable applications to specify both the message and the recipient(s) of the message. The application communicates to the Messaging service in OracleAS Wireless using SOAP and HTTP. OracleAS Wireless receives the message and delivers it to mobile devices using appropriate protocols such as SMS, E-mail, Voice, and others.
