SMS based information retrieval system for low end mobile devices

Abstract

Mobile phone is the most widely used portable device. Every mobile phone user can conveniently communicate with each other through SMS (Short Message Service) at very low price. It is so commonly used that, in some countries like China, an SMS culture has emerged. Although there are some SMS based applications in m-Learning, most of them are only for administrative purposes, like delivering messages to students as reminders or alerts for some learning activities. In this paper, we introduce a SMS Server [1] for querying information and knowledge by the use of SMS in a mobile learning environment. The proposed system consists of a GSM Module (GSMM), a Dialogue Control Module (DCM) which also works as a Querying Processing Module (QPM). GSMM includes a micro-controller and a GSM communication device with a SIM card in it.It processes the user's messages according to our defined protocol and acts as the interface between the mobile infrastructure and the rest of the system. DCM handles the content of the requesting messages and produces suitable querying tasks for QPM which in turn searches and matches information from Internet to produce suitable answering messages for the users according to their requesting messages.

IOT-based and Auto Firmware System for Transmitting Notifications and Advertisements via GSM/GPRS Modems

“…S. Biswas et el. [5] presented SMS-based information retrieval system which is designed especially for the users with low-end mobile devices in educational realm. The aim of this system is giving the ability to users (students) to search about specific information by sending a formatted query about this information via SMS message to the system.…”

“…Performance evaluation within this system is not adequate. It is clear that system in S. Biswas et al [5] can be considered a pull-based system.…”
