Abstract:

Machine type communications (MTC), defined as machine to machine communication over cellular mobile network is an integral part of future ubiquitous network and has broad application prospects and market potential. According to the typical application scenarios and features of MTC described in 3GPP TS 22. 368, four service models for MTC are proposed, namely non-mobility model, extended non-mobility model, low mobility model and full mobile model. The traffic flow and signaling overhead estimating method is developed to assess the bearing capacity requirement of operators’ networks under massive concurrent access from MTC devices, which is of prime important for designing efficient network planning and optimization strategies to enhance network performance and user experience.

Key words: machine to machine communication, machine type communications, service modeling, traffic analysis
