METHOD AND APPARATUS FOR SAVING ENERGY IN MOBILE COMMUNICATION SYSTEM BASE STATION |
摘要 |
<p>A method for achieving energy-saving in a mobile communication system base station, for application in an LTE system, comprises the steps of: determining the average value of a downlink sub-frame traffic load; determining, when the average value of the downlink sub-frame traffic load is below a threshold value therefor, an MBSFN downlink sub-frame which is not carrying multicast traffic; and closing the radio frequency channel corresponding to the multicast symbol in the MBSFN downlink sub-frame which is not carrying multicast traffic. By using the method in the embodiments of the present invention, the number of downlink sub-frames required to meet the communication traffic needs of a current cell is judged according to changes in the traffic load observed by measuring the traffic load values in that cell; sub-frames which can be closed are set as MBSFN downlink sub-frames which do not send multicast traffic; radio frequency channels occupied by the multicast symbol are closed, thereby achieving the object of reducing energy consumption.</p> |
