A M2M Client/Server System with CTI Functions and its Implementation

Abstract

This paper proposes an M2M client/server system with Computer Telephony Integration (CTI) that exchanges information between a human and objects in a Machine to Machine. In this method, HTTP protocol is used for the PULL-type communication and SIP protocol is used for the PUSH-type communication to perform bi-directional communication between the M2M client and the M2M server. Accordingly, a CTI server having a SIP server function and a Web server function is used for the M2M server. Furthermore, a Smart Phone having a SIP phone function as well as a Web browser function is used for the M2M client. In this study, an M2M system of a M2M client/server system with CTI functions is implemented and evaluated.
