5G Mobile and Wireless Networks

Abstract: In this paper explains about next generation 5G networks. 5G (5th generation mobile networks or 5th generation wireless systems) denotes the proposed next major phase of mobile telecommunications standards beyond the current 4G/IMT (International Mobile Telecommunication)-Advanced standards. 5G planning includes Internet connection speeds faster than current 4G, and other improvements. As the customer becomes more and more aware of the mobile phone technology, he or she will look for a decent package all together, including all the advanced features a cellular phone can have. In the proposed design the user terminal has possibility to change the Radio Access Technology -RAT based on certain criteria. For the purpose of transparent change of the RATs by the mobile terminal, we introduce so-called Policy-Router as node in the core network, which establishes IP tunnels to the mobile terminal via different available RATs to the terminal. Keywords: 5G, Radio Access Technology (RAT), VOIP (voice over Internet Protocol), D2D communication
