Description

Technical Field

[0001] The present invention relates to a system that provides services to these areas by remotely turning on and off RRU (Remote Radio Unit) devices in scenarios and time periods without user or traffic, thereby achieving energy savings for operators. Background Art

[0002] Today, RRU devices can be remotely turned on and off through systems based on (2G, 3G, etc.) and rectifier remote access systems, and the latter is achieved through a rectifier based on LVDS (Low Voltage Differential Signaling). However, none of these solutions can completely reduce the energy consumption of RRU devices to zero.

[0003] Therefore, in view of the deficiencies in existing research and current technologies, it is understandable that it is necessary to develop a system that can reduce the energy consumption of RRU devices to zero. Even when the RRU device is turned off, its energy consumption will still reach 30% of the energy consumption in a normal density environment.

[0004] The patent document EP3119122A1 in this field disclosed by the European Patent Office discloses a system for remotely controlling radio base stations and their devices. In the system of this invention, an out-of-band emergency channel based on the power line is established between the BBU (Baseband Processing Unit) and the RRU (Remote Radio Unit). Even if the only common public radio interface (CPRI) communication between the BBU and the RRU is abnormal, the BBU can still continuously and effectively control the RRU through this out-of-band emergency channel. In this invention, the BBU can effectively control the RRU. Summary of the Invention

The application program (3) is configured to generate commands on a preset basis (such as manual operation, date, or time) according to field attributes. The application program (3) is also configured to ensure that the written command triggers a scenario by analyzing its own KPI (Key Performance Indicators) value.

[0013] The BBU (4) included in the system (1) of the present invention is configured to establish a connection with the electronic device (2) through any communication protocol in the art, and implement data exchange with the application program (3) running on the electronic device (2) through the established connection.
