Power dynamic adjustment method and system for LTE base station

Abstract

The invention discloses a power dynamic adjustment method and system for an LTE base station, and the method comprises the steps: 101, judging whether each LTE cell in the LTE base station meets an adjustable condition or not, and adding the LTE cell as a to-be-adjusted cell into a power adjustment cell list if the LTE cell in the LTE base station meets the adjustable condition; andp 102, in the set adjustable date and adjustable time, judging whether the to-be-adjusted cell in the power adjustment cell list is adjustable or not every other adjustment period, and if yes, performing power adjustment on the to-be-adjusted cell in the power adjustment cell list through the open wireless network optimization parameters, and if not, not adjusting, the wireless network optimization parameters including CRS reference signal power, PA, PB, the number of transmitting antennas, the number of CRS ports and carrier bandwidth. According to the method and the system provided by the invention, the transmitting power of the base station is reduced as much as possible by automatically combining and setting the open network optimization parameters under the condition of ensuring that the user coverage perception is not changed when the service is idle, so that the overall energy efficiency level of the base station is improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and system for dynamically adjusting the power of an LTE base station. Background technique [0002] The LTE base station is a radio transceiver station that uses OFDMA technology to transmit information between mobile phone terminals through a mobile communication switching center in a certain radio coverage area. It can reach dozens of times that of TD-SCDMA technology, making ubiquitous high-speed Internet access possible. [0003] However, when the business is idle, such as between 0:00 and 06:00, the PRB utilization rate of the LTE cell will be low, and the number of connected users will be small. In this case, the operator provides the same base station as the busy hour The transmission power is obviously wasteful. Therefore, there is an urgent need to provide a power adjustment method to monitor the business of the cell in real time, and to reduce the transmis...

[0003] However, when the business is idle, such as between 0:00 and 06:00, the PRB utilization rate of the LTE cell will be low, and the number of connected users will be small. In this case, the operator provides the same base station as the busy hour The transmission power is obviously wasteful. Therefore, there is an urgent need to provide a power adjustment method to monitor the business of the cell in real time, and to reduce the transmission power of the base station as much as possible while ensuring that the user's coverage perception is unchanged when the business is idle.
