Method and device for controlling access of terminal for efficient use of resources in mobile communication system

Abstract

Embodiments of the present disclosure provide terminal connection control method and apparatus in a base station of a mobile communication system which supports a Carrier Aggregation (CA) function. According an embodiment of the present disclosure, a method for control a connection of a terminal in a base station of a mobile communication system includes determining whether there is a Primary Cell (PCell) connection request from a terminal with respect to an i-th cell (herein, i is a positive integer greater than 0 and equal to or smaller than k) corresponding to one of k cells (herein, k is a positive integer greater than 0) in the base station; if there is the PCell connection request from the terminal, determining whether to allow the PCell connection for the i-th cell of the terminal based on a threshold load corresponding to a maximum limit of a resource allocated to each cell; and if the PCell connection for the i-th cell of the terminal is allowed, determining whether to release a Secondary Cell (SCell) connection for at least one or more terminals which maintain the SCell connection for the i-th cell by comparing an i-th resource load allocated to the i-th cell with the threshold load.
