METHOD AND APPARATUS FOR SETTING BARRING FACTOR FOR CONTROLLING ACCESS OF TERMINAL CONSIDERING SLOPE OF CHANGE IN NUMBER OF ACCESS ATTEMPTING TERMINALS

摘要

Provided are a method and an apparatus for setting a barring factor in an access control technique of an access class barring scheme in a wireless communication network. According to one embodiment of the present invention, the method for setting the barring factor for controlling access of a terminal includes: a barring factor setting step of setting the blocking factor based on access attempt information of terminals; and a barring factor transmission step of transmitting the set barring factor to the terminal. In the barring factor setting step, one of beta distribution curves having a plurality of intervals is selected based on the access attempt information of the terminals, and the barring factor is adjusted by a difference value corresponding to the selected interval. According to the present invention, one of the beta distribution curves having the intervals is selected based on the access attempt information of the terminals, and the barring factor is adjusted by the difference value corresponding to the selected interval, so that an access success rate is increased and communication efficiency is increased as compared with an existing method when access attempts are rapidly increased.;COPYRIGHT KIPO 2017
