Next Generation Network (NGN) . The specific requisites that each access technology should satisfy to enable the formation of a global NGN infrastructure are normally designated by 4G (and beyond) requisites or IMT-Advanced requirements . Some examples of 4G requisites are interoperability with existing wireless standards, seamless connectivity across multiple networks, and ability to offer high end-to-end quality of service for multimedia traffic. Future networking environments will incorporate most likely, simultaneous usage of multiple access networks because the usage of smartphone terminals with multiple wireless interfaces is increasing exponentially.
The third part discusses some potential issues associated to the deployment of that technology in future networks; The final part of the current chapter highlights our major conclusions and future developments in the mobile access to future networks. L it e r a t u r e R e v ie w This section revises very relevant topics in future networks, as follows: • • Convergence on wireless access technologies; Support of mobile access. C onvergence on the Future W ireless Access As the network resources of point-to-point links in heterogeneous networks, with the increasing on data traffic , approach their own maximum capacity limits, researchers have developed a big effort to find effective proposals to manage the access to emergent Next Generation Network (NGN) environments in a way that the new challenging requirements could be efficiently satisfied with the available network resources .
Additionally, if HetNet networks are not utilized properly, it could cause issues with mobile handoffs, resulting in an increased number of dropped calls and connections. The final area of concern for service providers is that of making revenue. The costs of installing and maintaining the architecture for 4G technologies are expensive, and providers must recuperate those losses by gaining a higher number of customers. If a service provider adopts the new technologies without being in a financially sound position, it could be disastrous economically.
