Mobile Web Services (MobWS) are a promising technology for the integration of Information Technology (IT) and Telecommunication (TelCo) domains. The advancements in mobile communication and device technology, in terms of software and hardware, have revolutionized the focus of research and industry to investigate mobile service provisioning platforms and architectures. In this paper, we present a concept and architecture of a REST-Interfaced Mobile Web Server as a service delivery platform. Here, we discuss about the interaction strategy and URL-based access techniques for short-lived synchronousMobWS. The paper focuses on in-depth explanation of software architecture and its components of server and compares the payload requirements with the state-or-the-art SOAP based MobWS. The REST architecture has significantly reduced payload demands that shows promising signs of optimized processing performance of the mobile server when compared to SOAP.
