| 研究実績の概要 |
In the first fiscal of this project, we have focused on the development of the context-aware IoT system. We have made achievements as follows.
1) Context-ware IoT mobile router: We have designed and created IoT mobile router, which consists of Raspberry board, Sensor HAT board and LTE modem board. We attached the context-info such as sensor name and sensor device id to the trailer of data packet. The packet gateway, built with our deeply programmable FLARE node, will get the context-info of the sensor data and will perform traffic engineering accordingly. The prototyped system has been demonstrated in Japan IT week at Tokyo Big Sight during 2019/5/8-5/10.
2) Context-aware Private LTE. We have prototyped a context-aware UE slicing architecture utilizing in-network deep learning. In our implementation, we tag the downlink packets with the identified context info utilizing deep learning at the packet gateway (PGW) and transmit them to RAN slice with different spectrum resource blocks (RBs) and scheduling algorithms. The context info can be defined be as application name, location info or others as user defined. The work has been published in 3 papers and one paper got IEICE ICM English Session Encouragement Award.
3) High-speed PPPoE Router for home IoT network. We build a compact 10Gbps softwarePPPoE router on a commercial mini-PC for home IoT network, which can achieve much higher throughput than a commercial PPPoE router tested in a production environment. The related work has been presented at a conference, and the paper has been recommended for IEICE journal paper.

現在までの達成度 (区分)
1: 当初の計画以上に進展している
理由
We have done more development work and more publication than listed in our proposal. Our work has been highly evaluated by academia. One of our paper got IEICE ICM English Session Encouragement Award and another paper has been recommended for IEICE Journal paper.
Moreover, our work has attracted more and more interests from industry and we hope our work will have not only academic impact but also real application scenarios.

| 今後の研究の推進方策 |
In the second fiscal year, we have the following research plan.
1) We will continue the development and evaluation and do more publication as in the proposal.
2) To address the coverage problem of private LTE, we will cooperate with a mobile network carrier to integrate our private LTE network with a public LTE network, where the Home Subscriber Server (HSS) of the two LTE networks are shared or associated so that a user can migrate between the private LTE network and the public LTE network according to the place of use difference with only one SIM.
3) We will cooperate with a top security company in Japan to transmit their emergency messages via our designed IoT network, where how to detect emergency message will adopt our context-aware network technology.

| 次年度使用額が生じた理由 |
In the first fiscal year, our first-stage development have shared equipments (IoT devices, eNB and EPC) with other projects. Moreover, the international conference we attended was hold in Tokyo so we can save our budget of the first fiscal year.
In the second fiscal year, we need to buy more equipments dedicated to this project. Moreover, we plan to go aboard to attend international conferences. So the budget of this year will be increased comparing to that of the first fiscal year.
