Abstract
En 中文
This chapter presents the Third Generation Partnership Project (3GPP), including its ways of working, organization, and linkage to the world's largest regional Standardization Development Organizations (SDOs). 3GPP's work on Machine-Type Communication (MTC) from Release 8 to Release 13 is examined in detail. First, the main achievements made in Release 8-11 are described, and a focus is placed on the aspect of handling the large numbers of MTC devices expected to be served by cellular technologies. The chapter continues with a look at the work completed in Release 12 wherein the suitability of Long-Term Evolution (LTE) to support a large number of devices making infrequent small data transmissions, which is assumed to characterize many Internet of Things (IoT) applications, is reviewed. Also the features of Power Saving Mode (PSM) and extended Discontinuous Reception (eDRX) specified in Release 12 and 13 to facilitate device battery life of several years are presented. Finally, a glance at the Release 12 and 13 feasibility studies leading up to the normative work on Extended Coverage Global System for Mobile Communications Internet of Things (EC-GSM-IoT), Narrowband Internet of Things (NB-IoT), and Long-Term Evolution for Machine-Type Communications (LTE-M) is given.
