Abstract: The standardization of 5G wireless next generation networks is planned to be started by 3GPP consortium in 2020. Nevertheless, for today, there is the lack of QoS related 3GPP and ITU-T recommendations describing various popular services, for example video conferencing. The problem is to find the optimal bit rate values for this service not affecting the background lower priority services. In this paper, we propose a tool to solve this problem. The tool includes, first, a mathematical model of pre-emption based radio admission control scheme for video conferencing and background video on demand, and second, an effective algorithm for calculating QoS parameters for these services. The results of the paper could be used to find the optimal bit rates for video conferencing and further develop a proposition for standardization activities in video conferencing recommended parameters.

Keywords: 5G, LTE, video conferencing, video on demand, radio admission control, pre-emption, service degradation, service interruption, QoS, blocking probability, pre-emption probability, mean bit rate, teletraffic theory, queuing theory.

Abstract: With progress of social globalization, global standards are becoming more important. This means that more human resources should be developed who are engaged in standardization. To realize lively situation of the global standardization education in universities, it is very important to know the programs, courses and their contents for the education about global standardization in universities. In this paper, firstly, current situation of education about global standardization is studied. As a result, 3 education programs consisting of plural courses and 45 courses were found. Secondary, a new crawling technology to collect syllabuses of courses published on the websites of universities is proposed. Also, a new method of knowledge extraction from the crawled syllabuses is proposed. Using these technologies proposed, syllabuses of 132 Japanese universities including all the 88 national universities were crawled successfully. As a result of the knowledge extraction of the global standardization courses from the syllabuses crawled, it is made clear that 45 courses about global standardization education are offered by 24 Japanese universities. This paper also shows a result of knowledge classification of the 45 syllabuses.

Keywords: Standardization, Education program, Crawling, Course, Knowledge.

Abstract: In this paper we present an end-to-end mobile communication testbed that utilizes various open source projects. The testbed consists of Global System for Mobiles (GSM), General Packet Radio Service (GPRS) and System Architecture Evolution/Long Term Evolution(SAE/LTE) elements implemented on a virtual platform. Our goal is to utilize the testbed to perform security analysis. We used virtualization to get flexibility and scalability in implementation. So as to prove the usability of the testbed, we reported some of the test results in this paper. These tests are mainly related to security. The test results prove that the testbed functions properly.

Abstract: This paper presents a creative lightweight solution to package any existing VNF (Virtualized Network Function) to support ETSI NFV (Network Function Virtualization) architecture quickly and easily. The preconditions of existing VNF are quite straightforward and simple, such as running on Virtual Machine (VM) and Operating System (OS) supporting Secure Shell (SSH) commands. With our solution, the new VNF (Virtualized Network Function) will have the additional functions required to integrate with ETSI NFV architecture, without redesigning the existing Element Manager. This will include VNF Descriptor, lifecycle management benefits such as deploy within minutes, scale out/in on demand, etc.

Keywords: NFV, VNF, VNFM, EM.
