Abstract:

The energy-saving methods are infrequent on hybrid energy supplies, a new energy-saving management mechanism from cell viewpoint was proposed. The mechanism firstly constructs energy-saving optimization model with hybrid energy supplies and modeling evaluation method for service quality. To resolve the optimization model, a regional energy-saving algorithm from the perspective of cell compensation was analyzed thereafter. Through simulations under urban universal mobile telecommunications system scenarios, it is shown that the mechanism can keep coverage and service quality on acceptable levels, reduce regional interference distributions, and saving about 34% energy for power grid, which takes on significant green economic importance.

Key words: cellular networks, hybrid energy supplies, energy-saving management, cell compensation
