Research on Access Mechanism of Massive Machine Type Communications in Industrial Internet of Things

When facing the application of industrial Internet of things, the main problem of massive Machine Type Communications (MTC) is that when massive MTC devices directly access the cellular network, it will cause congestion, which will cause some MTC devices and cellular user devices unable to access the network normally, and at the same time, it will cause huge signaling overhead in the cellular network. In order to solve these problems, this paper first analyzes the principle of massive MTC related access mechanism, proposes a massive MTC device resource management mode based on cluster mode, and gives the static and dynamic management mechanism of cluster. This mechanism takes the optimal cluster size and the fairness principle of cluster members into account. In the case of limited cellular resources, it can achieve reliable access to massive MTC.
