Abstract(in English) To provide cellular communication for a large number of IoT devices, a large number of servers are needed to increase the amount of computational resources in mobile core networks (EPC). This is because the EPC needs to keep state information of the devices even if they do not send data. This paper proposes a method for reducing the state information of IoT devices. The proposed method assigns the same international mobile subscriber identity (IMSI) to multiple IoT devices, which upload data with the same cycle, and manage them to upload data with different timings. This paper shows that the proposal can provide cellular communication lines for one hundred or more IoT devices by using only the single IMSI.
