At present, the energy consumption of wireless communication network accounts for the vast majority of the operator's expenses. A cooperative energy saving mechanism is proposed in the framework of the self-organized network, based on the hybrid energy supplied, aiming at the energy consumption of cellular is too large and the utilization rate of green energy is low. According to the framework, the...
Reducing the energy consumption (EC) of base station (BS) is one of the major concerns in wireless cellular networks. Additionally, turning off some underutilized BSs during off-peak period and performing effective compensation without delay are the most efficient way to save energy. However, large-scale energy conservation yet remains to be investigated at macro level. In this paper, to solve the...
Load balancing is one of the key target of LTE Self-Optimization Network (SON). In this paper, we propose a load balancing method for LTE downlink network, namely Load Vector Minimization based Load Balancing (LVMLB) method. Load Vector (LV) is a vector whose elements are the load values of cells and sorted in descending order. The order of LVs is defined by the lexicographical order. The smaller...
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...
In this paper we present an autonomous load balancing algorithm for downlink LTE network, the ripple form reference signal received power based load balancing algorithm (RF-RSRPBLBA), which mainly requires the reference signal received power (RSRP) and cell load information. In RF-RSRPBLBA, overloaded cells distribute their surplus load in a greedy manner. As a general character of greedy algorithm,...
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...
The requirement of QoE is gradually increasing currently. Simultaneously, as the intermedium between the users and network, devices support collecting several QoS parameters which could predict expected QoE for users. However, a large quantity of mobile devices will become the obstacle for the QoS collection due to the costs of collection traffic. To solve it, this paper proposes a framework for collecting...
