Patent ID: 11184795

Abstract:
Disclosed are methods and systems for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system. The disclosed methods and systems can be applied to intelligent services on the basis of 5G communication technology and IoT-related technology. More specifically, a communication method of a terminal in a mobile communication system comprises: receiving, from a base station, system information including application specific congestion control for data communication (ACDC) configuration information for indicating whether to apply ACDC to a terminal belonging to a home public land mobile network (HPLMN); determining whether to permit access to the base station on the basis of parameters relating to the ACDC, when the application of the ACDC to the terminal belonging to the HPLMN is set according to the ACDC configuration information; and communicating with the base station according to the determination result.
