Abstract

The invention discloses a carrier aggregation control method and device and a base station, and relates to the field of mobile communication. The method comprises the steps: periodically obtaining theload evaluation index information of a cell; adjusting an auxiliary carrier activation condition and/or an auxiliary carrier deactivation condition based on the load evaluation index information; obtaining the data transmission measurement data of user equipment; activating the auxiliary carrier of the user equipment or deactivating the auxiliary carrier of the user equipment when the data transmission measurement data meets the auxiliary carrier activation condition or the auxiliary carrier deactivation condition. The method can achieve the dynamic adjustment of a threshold value of a decision-making parameter in the auxiliary carrier activation condition and the auxiliary carrier deactivation condition according to the load condition of the cell, can achieve the more effective use of resources, can adapt to the changes of a network environment more flexibly, can enable the number of access users to be optimal, and improves the stability of a system.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular to a carrier aggregation control method, device and base station. Background technique [0002] Carrier aggregation CA is one of the key technologies to realize 4G+. Through carrier aggregation, operators' discrete spectrum resources can be fully utilized to maximize resource utilization. At the same time, carrier aggregation users can also obtain better uplink and downlink peak experience. In the implementation of carrier aggregation, after the main carrier adds a secondary carrier, the activation and deactivation conditions of the secondary carrier are mainly the preset threshold values ​​such as the amount of cached data, time delay, and channel quality. The basic flow of existing carrier aggregation secondary carrier activation is as follows: set the threshold value of parameters related to carrier aggregation secondary carrier activation, such as user...
