The current power consumption of intelligent terminals are over burden for their battery capacities, which directly restrict the hours used. In order to realize the energy saving of terminals in the LTE-A system, this paper puts forward the concept of virtual cells and a related uplink energy saving mechanism. Virtual Cell's resources and the outage probability of terminals are proposed by this mechanism...
For the sake of the increase of energy consumption, the emission of carbide can't be negligible. In this paper, we propose a mathematical model which adjusts the radius of base station, to figure out the problem of energy saving, while the quality of services such as the traffic volume of each base station and the service area should be satisfied. For the model, we use ant colony algorithm as a practical...
Cell Outage Management (COM) is a functionality aiming to automatically detect and mitigate outages that occur in radio networks due to unexpected failures. In this paper, we assume that future Radio Access Networks (RAN) can autonomously detect an outage based on measurements, then we propose a Genetic Algorithm (GA) based mechanism for Cell Outage Compensation (COC). COC is achieved by a GA- based...
Energy issue of cellular access network has drawn much attention in the recent years. In this paper, we propose a Novel Energy-Saving Cell Selection Mechanism (ESCSM) including the energy-saving triggering conditions determination and a regional cell selection algorithm based on traffic. ESCSM selects the BSes which can be switched off without any negative effects to the radio coverage and service...
