Voropaeva A. New generation wireless telecommunications networks optimal control methods

Research object is next generation wireless telecommunications networks processes functioning. Research purpose is wireless telecommunications network control improving based on optimal control methods. Research methods are the methods of operations research to solve optimization problems, methods of idempotent algebra to represent a new generationwireless telecommunications network as a discrete-continuous system, mathematical modeling methods for the researching a new generation wireless telecommunication network model. Scientific novelty: 1. Improved method determining the controllability state of discrete-continuous system, which is in contrast to the well-known, allows on information about the state of the LTE system by determining the sequence of control actions to determine the controllability of the system. 3. First developed dual objective utility function for wireless telecommunication network, which takes into account the ratio of duplex data exchange sessions and allows optimal reallocation of network resources. 3. First developed a method of resource management new generation wireless telecommunication network, which, in contrast to the known, based on the proposed dual network utility function takes into account the cost of use of resources and ensure optimal network mode. 4. First developed a control the speed of transmission method, which, in contrast to the well-known, takes into account the satisfaction of the subscriber service and increases the efficiency of resource allocation. Practical results: 1. The structure of the control system, which is based on the proposed optimal control methods improves the performance of new generation wireless telecommunication network of 8% to 21% for different types of services. 2. Developed software definitions handling state discrete-continuous system and the calculation of the optimal number of resource blocks wireless base station network of new generation when changing the state of the system. 3. Some results of a study made for the introduction of the transition to 4G standards MTS-Ukraine (active implementation of 13.03.2014).
