Problems solved by technology

There is a problem here, that is, if the traffic volume is small in a certain period of time, and the processing capacity of one BP single board can be completed, two or more single boards may be required to participate because the allocation relationship remains unchanged. business, increased energy consumption

Embodiment Construction

[0060] In view of the problems existing in the above-mentioned existing technologies, if the working status of peripheral single boards and power amplifiers can be properly adjusted through automatic detection without affecting the quality of network service, in practical applications, the business can be concentrated on a small number of Among the BP resources, power off idle BPs to minimize power consumption. In actual application scenarios, if the RRU's external power supply fails, the internal power supply can support it for a period of time to maintain user access. In this case, if some idle DTRUs can be turned off, it will be an invisible improvement for the emergency repair of the network and the service quality of the network.

[0061] In view of the above reasons, the embodiment of the present invention provides a remote radio system, including BSC and BTS, which can realize that within a specific time period configured by the user, the BSC can detect the traffic volu...

Abstract

The invention provides a method and a device for energy conservation of a remote radio frequency system. The method includes the step that telephone traffic of a cell is detected by a base station controller, and if the detected telephone traffic of each line in the cell is smaller than a first threshold, partial or all logic carrier frequency in the cell is chosen to be in power-off. The method and the device can achieve power-on and power-off of an automatic control single plate, and can save energy.

Description

technical field [0001] The invention relates to a system energy-saving and consumption-reducing mechanism in a GSM mobile communication network, in particular to a base station system energy-saving and consumption-reduction based on the separation of baseband and radio frequency. Background technique [0002] The base station subsystem (BSS) of GSM (Global System of Mobile communication) can be divided into two parts: the base transceiver station (BTS) and the base station controller (BSC). The BTS is responsible for wireless transmission, and the BSC is responsible for control and management. . The BTS can deploy multiple cells, and each cell is composed of one or more radio transceivers (TRX), and each TRX handles signal processing, radio reception and radio transmission on eight physical time slots. In principle, TRX can be divided into a baseband processing unit and a radio frequency processing unit. In the design of the mobile communication system, as the traffic dens...
