Abstract

The invention relates to a dynamic control method and device for a remote radio unit, and relates to the technical field of communication. The method comprises the following steps: determining the state of a base station according to the service volume information of the base station in a preset time period; wherein the state of the base station comprises an idle state and a busy state; under the condition that the base station is changed from the busy state to the idle state, determining the number of cells to be updated of the base station according to the service volume information of the base station in a preset time period; wherein the number of the cells to be updated is smaller than the number of the current cells; according to the number of the cells to be updated, changing the cell identifier of each RRU corresponding to the base station, so that the number of different cells to which each RRU belongs after changing is the same as the number of the cells to be updated; and for each changed cell, part of RRUs are selected to be closed, and the transmitting power of the remaining RRUs is improved to reach the area range corresponding to the coverage cell.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular to a dynamic control method and device for a radio remote unit. Background technique [0002] In the 5G era, the working frequency band of the communication network is relatively high, and the traditional passive indoor distribution system (DAS) cannot work in this frequency band. Such as figure 1 As shown, the newly emerging digital indoor distributed system with a three-level structure of baseband unit (BBU), remote convergence unit (rHub), and remote radio unit (RRU) equipment is beneficial to the realization of indoor network coverage and further development of equipment in the future. However, in the 5G indoor network, it is necessary to use a large number of small radio frequency remote units as support to meet the network coverage and people's demand for high-speed Internet access, which makes the system cost and power consumption higher.
