LTE, LTE-Advanced and WiMAX: Towards IMT-Advanced Networks

Network Intelligence

Services utilizing network and location analytics are already emerging in the smartphone applications market. Meanwhile, the proliferation of various sensing and actuating platforms, for example, ANT+ and IQRF, that interface directly with mainstream smartphone and network access types will soon allow for more valuable services that are more prompt, reliable and relevant. In this interweaved connectivity between context and personal preferences (both through settings and through non-invasive profiling), in addition to the service infrastructure of social networking platforms, the users' wireless and mobile experience will become much more enhanced. Another dimension of interest is that of utilizing network information to discern physical properties. Many examples of this have been displayed, both in research and industry. One of the commercial examples involves utilizing network traffic levels in recognizing actual street congestions [10].

For the considerations of access network operation, however, functionalities that employ network analytics include instilling reliable wireless communication, interference management and mitigation, power management, resource allocation, and reduced energy. Both LTE and WiMAX support various mechanisms for autonomous operation of network entities, and have made provisions for self-optimization in various aspects of their respective standards. For example, the operation of femtocells cannot do without autonomy, especially ...
