Here we analyzed the need, concept, service and features of fifth generation communication technologies in this paper. It was proposed the core technology incorporated with 5G and their architecture. Future trends and applications influenced by the 5G communication system were analysed.


Introduction
The very first generation of an analog signal-placed mobile communication network was built in the 1980s and backed people to get rid of telephone line shackles. Most effective second-generation (2G) mobile communication systems based on digital communication emerged in the 1990s, and personal mobile communications grew rapidly on a larger scale. After 2000, people can appreciate rapid mobile Internet experience with the implementation of 3G systems, like video telephony. By 2010 deployment of the 4G commercial network based on Long Term Evolution (LTE) in addition heightened user experience and system capacity. The Global TD-LTE Initiative (GTI) statistics conveys, by the third quarter of 2015, 364 LTE commercial networks were started. The 5th-Generation (5G) mobile communication technologies are up coming into research fields with the IMT-Advanced (IMT-A) systems being set up in the world.
Intensive implementation of the Fifth-Generation Mobile Communications System (5 G) have been driven globally as a systematic upgrade of current mobile communications systems focused on extensive industry dynamics analysis and potential demands for mobile communications systems towards 2020s. European Union's initiative METIS began 5G research work by the end of 2012 to accelerate potential progress of mobile communications techniques. In China, the sponsor team IMT-2020 was formed in April 2013. Promotion community IMT-2020 will act as a forum to support the 5 G report. Its goal is to plan domestic factions to constantly engage in international cooperation and collectively support 5G global development. In Korea, Samsung certified and documented millimeter wave technical expediency is around 28 GHz bands. Other possible contender technologies like massive MIMO have increasingly drawn attention. The International Telecommunications Union (ITU) has begun their research towards 2020 on the International Mobile Telecommunications Network.

Overview
LTE's global introduction cultivates the smartphone consumers to make massive use of cellular data in their day to day affairs. For example, the video services and social apps like WeChat, Facebook, and Twitter, greatly alternated our lives with LTE's effectiveness, especially with huge data rates and low latency. Mobile communication is believed to penetrate into every facet of the prospective society and create an all-dimensional, user-centric knowledge ecosystem. In the near future, a fully mobile and wired society is anticipated which will be characterized by exponential advancement in connectivity, traffic volume and wider field of user scenarios. The Mobile Broadband (MBB) and Internet of Things (IoT) services will have two prominent key drivers in the prospective development of mobile communications, providing a wider perspective over the next generation of mobile communications (5G).

Need
Mobile broadband service has changed the traditional mobile communications business model, allowing for unparalleled user experiences and having a significant effect on whole form of the life and work of people. Moving forward to 2020 and maybe beyond, MBB service will facilitate the continuing transformation of how people communicate and provide consumers with the ideal opportunity through more technological innovations such as augmented reality (AR), virtual reality (VR), ultrahigh-definition (UHD) 3D content, and mobile cloud services. An added advancement of the mobile Internet will activate the expansion of digital traffic in the future by amplitude of thousands, promoting a new age of modifications and an insurgency in mobile communications technology and the whole industry. Going forward to 2020 and beyond, mobile data traffic is expected to surge explosively. The worldwide traffic is believed to rise more than 200 times between 2010 and 2020, and nearly 20,000 times between 2010 and 2030.

Scope
The IoT has broadened its reach of mobile communications services from interpersonal communications to the intelligent interconnection amidst subjects as well as between people and things, letting mobile communications innovations enter toward larger disciplines as well as sectors. Considering 2020 and well beyond, technologies like mobile safety, the smart home, environmental monitoring, Internet of Vehicles (IoV), and industrial control would accelerate the exponential production of IoT applications, enabling the linking of billions and billions of users to a network creating an accurate "Internet of everything." It creates unprecedented-scale of newly surfacing industries and will inculcate limitless creativity in mobile communications. In the meantime, mobile

Features
To order to satisfy service and customer demand by 2020 and beyond, the IMT-2020 is expected to be launched by 2020 (5G) to satisfy current to unparalleled demands beyond previous generation systems' capabilities. 5 G will develop and leap the constraint, space and time in order to allow an innovative as well as engaging user experience. 5 G would provide consumers with a fiber-like data access rate and a user experience of "zero" latency. It will also be able to communicate 100 billion devices and will be efficient of distributing seamless experience among a range of scenarios which include ultra-high mobility, ultra-high connection density and ultra-high traffic volume density. It also offers strategic optimization focused purely on resources as well as user experience, which definitely increases energy which cost efficiency through more than a hundred times, helping to understand 5G's dream, "information a finger away, everything in touch."

Services
The impending cellular communication system is going to reach all the fields of community or population and offer the seamless experience of users. In order to obtain the specifications for the 5 G network, the standard infrastructure and customer demand will be the required specifications for the 5 G, although the usual implementation circumstances would also present certain impediments to be addressed by the 5 G system , in particular private and commercial application viewpoint, by its price and efficiency.

Sustainability and Efficiency Requirements
To afford the users with the mesmerizing services in a more economical manner, when dispatched and sustained after commercial deployment, the expense and reliability of the 5 G system must be regarded. Mobile data traffic by 2020 may rise more than 1000 times, although the consumer cannot compensate roughly to the data volume for the mobile data. To do that, a key to making a good 5 G would be the network's high price-efficiency. The 5 G spectrum performance, the agility to adjust to diverse use circumstances and facilities, and streamlined network optimization and maintenance are eagerly anticipated from 5 G to the value per bit of 5G.

5G mobile network Concept
Having considered the actual introduction of 5G mobile communications networks, it would include both cellular networks and fixed network dimension, consideration will be given to the value of technical advancement regarding the design of the entire communication network. In Japan, the mission of the 5G network committee is to perform out the studies mentioned above. The Committee paid particular consideration to end on communication aspect and observed the need to create fixed network technologies in order to facilitate a reduced latency in transmitting or wider bandwidth properties in the core network segment, as essential requirements of 5G networks, highly malleable resource control similar to radio networks accessibility.

Network Architecture
Initially, 1G is a wireless technology Analog Telecommunication standard here radio signals were transmitted with analog system, and speed of these lies in the range 2.4 kbps. These systems often encounter problems such as poor battery life and low voice quality this would finally result in problems such as dropped calls. Finally to get rid of this problem 2G Cellular technology was introduced in which radio signals were transmitted in digital form and speed of these devices range in 64 kbps. The 3G then provides 144 kbps-2 mbps capacity, while 4 G provides 100 Mbps-1 Gbps and is based on LTE technology. The 5 G infrastructure is improved. the network components and different end-points are upgraded to provide a new situation. Consequently, new technologies to incorporate value added services must be implemented for service providers. The 5 G architecture is entirely IP-based and for Wi-Fi and mobile networks. The 5 G model primarily includes a user terminal and then a range of different radio access technologies. Each radio technology is regarded as an IP link for the outside world. It also continues to distinguish the changes in its environment and thus react to the continuous quality of service. As the system is more reliable, less complex, and more effective as it handles all new implementations based on 5G. There are three major categories of the use case for 5G: 1. The Internet of Things (IoT) has also been named massive machine-to -machine contact, involving connectivity of billions of devices on an unparalleled scale without human interference. It will revolutionize current industrial processes and systems, including agricultural, manufacturing and corporate communications. 2. Important tasks include real-time computer controls, industrial robotics, vehicle communications and safety systems, autonomous driving and stable transport systems. In the field of remote education, treatments, and treatment, low-latency contact also presents new possibilities. 3. Better mobile broadband that provides much faster data rates and higher worldwide availability. Current features provide free Wi-Fi Internet access for domestic consumers, outdoor TV systems with no need for cable transporters and greater smartphone connectivity.

SECURITY SERVICES
The 5G networks provide opportunities for new technologies, business models, and mobile market entry for emerging players. 5G's key goal is to create a robust and trustworthy innovation platform for companies and industries to build and offer innovative, value added technologies for mission-critical uses like Power, Tr. This network facilitates flexibility and cost-effectiveness of multiple networks for different customers with varying infrastructure and safety requirements. It mainly works on a trust model of three parties consisting of network operator, service provider and end user. This method extends from the consumer interface across the network to the point where the operator finishes its services. At network level, the transportation layer network plays an important role in 5G systems as it offers high-speed connections and low latency between all 5G network functions. The accessibility of the transportation network is consequently linked to the 5G and its service providers. In failure: Georedundant tracks permit the routing of traffic in the event of a track failure Link redundancy solutions will recover if fast failure, connection failure or port failure occurs. Port-based authentication to check whether approved network devices are linked to network. Error identification and mitigation methods are available.
5G will link critical infrastructure requiring greater protection, as well as critical infrastructure to ensure the security of the entire community. For example, a security breach in online power systems can be devastating for all the electrical and electronic systems on which society depends. We are also aware that it is important to have data for decision-making, but what about critical information being corrupted during 5 G networks. It is therefore more essential that primary security challenges in 5G networks are examined and highlighted and that potential solutions can lead to 5G secure systems overviewed.
The basic challenges in 5 G highlighted and heavily discussed in literature by the Next Generation Mobile Networks (NGMN) [2] are:  Network flash: large number and new (IoT) end-user apps.  Radio interface security: radio coding keys sent through unsafe channels.  Integration of the user plane: no defense of user data plane cryptographic integrity.  Mandated network security: service-driven security architecture limitations that allow security measures to optionally be utilized.  Password roaming: The roaming from one operating network to another cannot adjust user security parameters which compromise the threat to roaming.  Denial of Infrastructure Service Attack (DoS): accessible and non-encrypted network control networks.  Storm signaling: central control systems, for example. The Non-Access Stratum (NAS) framework of Third-Generation Partnership Project (3GPP).  DoS attacks on end user devices: No controls, programs and user configuration details of the operating system.
