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.

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.

Abstract: This paper presents the recently created NFVRG within the IRTF, outlining
the story of its constitution, describing and analysing its charter, and
presenting the results achieved so far (in despite of its short lifetime)
and the intended goals, especially in the short-mid-term.

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.
