WORKING TOGETHER : EDUCATION , RESEARCH AND DEVELOPMENT FOR 5 G NETWORKS

In the new world of globalization of ideas and mobility difficulties in knowledge diffusion still remains. The effective exchange of experiences and skills in new generation networks is not guaranteed by the enormous potentials ofinternetworking systems and devices. Conceptual model for performance modeling and evaluation of multiservice networks has been major interest for mobile networks providers. It is essential to assess the performance of mobile system architectures in order to identify where potential bottlenecks and data packet blocking probability are possible to occur. Educational platforms, new simulations opportunities represent a good opportunity to reduce the digital divide and to ensure faster and higher communication trends. Several universities and companies are currently involved in using educational platforms to provide better results. Conceptual model for teletraffic engineering in educational platform and applications focuses on some important aspects: tutorials, exercise, simulations, and expectation values of parameters, testing and estimation of students work. In the same time the same model is very appropriate for simulation of network management for the new generation networks. This educational platform for academics, students and researchers, puts together some of the critical aspects of distributed systems and their characteristics, parameters and probability of blocking.


INTRODUCTION
Defining the conceptual model for educational platform for Teletraffic Engineering is one of the main parts in student education.In this case the applications focus on network management for the new generation networks and distributed computing technologies.Besides it presents emerging technology trends and advanced platforms.This educational platform for academics, students and researchers, puts together some of the critical aspects of distributed systems, their characteristics and probability of blocking.
Teletraffic simulation for educational purposes, utilizes complex models to study complicated telecommunication problems.Those models include data modeling for objects, behavior models for interaction, and other algorithms such as randomization, variations, blocking etc.As no unique model fits every scenario, researchers from transportation community are investigating new customable simulation models continuously.This paper, thereby, presents a prototype of a research and education oriented simulation platform, which helps researchers and students to reduce their workload by providing a compact data structure, a friendly interface, and essential automation procedures, with teletraffic simulation [3,6,9].

ADVANTAGES IN "WORKING TOGETHER"
Teletraffic theory is defined to solve problems with planning, performance evaluation, operation and maintenance of telecommunication systems [5].First theory was illustrated by examples from telephone networks, but nowadays the students are not interested in such topics.In 5G mobile networks the necessity of traffic measurement and quality of service must be observed [2].Working together developers, researchers and students define some critical aspects in network.The idea of the educational development of models, algorithms and simulations make consolidation and exchange of experience of interests in the two groups [1,2].
Research methodology is suggested for students of corporate strategy in order to attain generalizability and statistical significance in reporting findings while not losing the understanding of teletraffic engineering [7] Research and Development departments are common in many larger companies and universities working with newer products or technologies subject to important shifts [10].
While research and development work can be instrumental in creating new products or adding features to old products, the work that the department does is more complex than simple innovation.R&D is connected to marketing, cost management and other parts of business strategy.

5G TRENDS
The trends of 5G mobile access is to be built upon new radio access technologies, evolving 4G, LTE, HSPA, GSM and Wi-Fi.The new requirements are widely varying.The services, devices, number of clients are in super wide variety.
The new communication needs of a massive deployment of various devices, such as with low complexity parameters to more advanced parameters.The industrial and medicine devices must be lifesaving.
The services must be amazingly fast in very dense crowds of users [1].The fast connections is a key factor for success of development of so important services as health and security sectors, fire brigade, high speed trains and cars (Fig. 1). The

The Quality of Experience requires fully connected users not only for static users.The expectation of connectivity is no matter where or how one is moving [1].Highly mobile devices, e. g. trains and cars, are communicating machines for this scenario, but also sensors related to widely varying applications, e.g.moving components in industries, plants, other vehicles [8].
Data networks [3,4], broadband networks, Broadband Convergence Networks, ATM, fast IP networks, all generations of mobile secular networks are extremely growing network, in a contrast to the conventional cable systems [9,10,11].The future engineers must be with very high knowledge in all areas of telecommunications.

REQUIREMENTS FOR SIMULATION PLATFORM
The main idea of the simulation platform is to cover different aspects of data communications and telecommunications.The future engineers must be with very high knowledge in all areas of telecommunications.
It will be implemented on .NET [12].Presented work introduces a part of conceptual model of the whole simulation platform, including: The model includes modules for education, tests, student's research and programming of different networks.In the past the teletraffic theory was illustrated examples of non-digital telephones and technologies.But nowadays the task is to design systems as cost effectively as possible with predefined quality of experience, grade and quality of service especially, when we know the future traffic demand and the capacity of system elements.Even the most important task is to specify the methods for control, to specify emergency actions when system is overloaded or blocked.This is a necessary step for applying the theory in the practice, a series of decision problems.
Modeling of various telecommunication systems must describe the whole or a part of the system.The requirements of the modeling process for new applications are knowledge of: technical system; mathematical model and implementation of the model.New telecommunication systems must be defined with: system structure, operational strategy and statistical properties of the traffic.
Data networks [11,12], broadband networks, Broadband Convergence Networks, ATM, fast IP networks, all generations ОГЛЯДИ ТА РЕКЛАМНІ МАТЕРІАЛИ of mobile secular networks are extremely growing network, in a contrast to the conventional cable systems [1,6,7].Three simulation teletraffic modules, HeavyQueues, ComplexQueues and HandoverSchemes, ensure a platform for data modeling, simulation flow, and user interfaces, respectively.The nature of the dynamic structure lets users an easy work with the complicated simulation program by extending the default essential data and simulation models and plugging in the partitioned simulation flow.The simulation experiments for the next generation mobile networks have to be realized with different teletraffic systems.The realization of this conceptual model will be developed with .NET Framework, which can operate with 15 different programming languages.His main component-Common Language Runtime operate with Visual Basic .NET for realized simulations [12].

Single
The working groups [1] defined 5G network requirements for simulation as:  1 Gb/s to be offered, simultaneously to tens of workers on the same office floor;  Up to Several 100,000's simultaneous connections to be supported for massive sensor deployments;  Spectral efficiency should be significantly enhanced compared to 4G;  Coverage should be improved;  Signaling efficiency enhanced.Although these requirements seem quite vague they are targeting three foreseen problems for year 2020, which is the aimed time frame for succeeding the development:  Avalanche of traffic: Explosion of the number of connected devices.From 5 billion (2010) to 50 billion (2020).Keywords are Internet of things, e.g.wearables, housing;  Large diversity of use cases and requirements: guaranteed service level, reliability ,latency ,device capabilities, Device-to-Device;  Communications Car-to-Car Comm.rapidly developing Advanced Driver Assistant Systems (ADAS), e.g.
Infotainment Systems, Traffic jam assistants, also autonomous driving is aimed as vision for 2020.
For a more detailed view at vehicle to vehicle communication, we need to take a closer look at the requirements to enable this and to work out the obstacles that have to be dealt with.The METIS2020 research group has therefore designed a scenario to visualize the problem and demand for traffic safety and efficiency [9].
The main challenges of this test case lie in the required reliability, availability, and latency of automotive safety services.A maximum network end-to-end delay (including device detection, connection setup and radio transmission) of 5 [ms], with transmission reliability of 99.999% should be guaranteed to deliver the drive safety service.
