METHOD FOR ENERGY SAVING IN A MOBILE COMMUNICATION SYSTEM
First Claim
1. A method for energy saving in a base station, comprising:
- obtaining energy saving priority information of the base station and its adjacent base stations from an OMA unit; and
determining whether the base station is a candidate energy saving base station or a candidate compensating base station according to a load of the base station and the energy saving priority information of the base station and its adjacent base stations, wherein the base station is a candidate energy saving base station when the base station has the highest energy saving priority and the load of the base station is below a first threshold or a second threshold, and the base station is a candidate compensating base station when the load of the base station is below a third threshold and the base station does not have the highest energy saving priority,wherein the third threshold is above the first threshold, and the first threshold is above the second threshold.

Abstract
A method for energy saving in a mobile communication system—is provided in the invention. In the mobile communication system. OAM unit performs centralized management of the energy saving priorities. The respective base station obtains energy saving priorities thereof and energy saving priorities of adjacent base stations, and determine whether it is a candidate energy saving base station or a candidate compensating base station according to a load condition thereof, and energy saving priority information, thereof and energy saving priority information of adjacent base stations. The candidate energy saving base station can communicate with the adjacent base stations to negotiate about entering an energy saving procedure. With the technical solutions of the invention, OAM unit performs centralized management of the energy saving priorities, and each base station, can determine dynamically whether it is a candidate energy saving base station or a candidate compensating base station according to a load condition thereof, and energy saving priority information thereof and energy saving priority information of adjacent base stations and communicate with the adjacent base stations to negotiate about entering an energy saving procedure. Thus it is possible to accommodate flexibly and effectively a change to the load conditions so as to realize the energy saving of the system more reasonable with an alleviated influence of the energy saving procedure on the performance of the system.
