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...

AI Technical Summary

Problems solved by technology

[0004] 1. Each parameter in the trigger condition is a preset fixed threshold value, which cannot be optimized and adjusted according to the load condition of the carrier itself.

[0005] 2. When the carrier is relatively idle, if the preset threshold value is high, it will make it difficult to activate the secondary carrier, which is not conducive to maximizing resource utilization

At the same time, when the carrier load is high, if the preset threshold value is low, more CA users will reduce the number of RRC connection users that can be accessed by each carrier, making it difficult for new users to access, etc.
