Short Message Service for Internet-Mobile Platform

In 2003, the Parlay group proposed a concept and technique of the web service and proposed the other suite of Open Services Architecture (OSA) specifications, Parlay X. The Parlay X Application Programming Interface (API) defines a set of easy-to-use API, which utilizes the web service for application developer to access telecommunications functions more easily. In this paper, we use Parlay X-based Internet-Mobile platform called IBM WebSphere software for Telecom (WsT). To accommodate the telecom services (i.e., Short Message Service (SMS), Multimedia Messaging Service (MMS)) on IBM WsT, a set of API named OpenAPI is implemented. The paper studies the SMS behaviors and investigates the OpenAPI SMS performance. To improve the OpenAPI SMS delivery delay, a timeout timer is implemented. Our research also predicts SMS delivery failure and provides guidelines to select appropriate timeout timer values for OpenAPI SMS.
