Abstract:
A dynamic overload control device in a digital mobile communication system, comprising:a data base for storing thresholds obtained at each point used for determining an overload; drive means installed in a base control processor (BCP) and a central control processor (CCP), for allocating an overload control process according to the thresholds of each point, used for determining the overload, stored in the data base, and starting the overload control process; overload detect means for periodically detecting activity ratios in the BCP and CCP and a call resource occupancy rate in a base trasceiver station, and determining the overload after comparing an overload detect value with the thresholds obtained from the drive means; overload process means for processing the overload after selecting one between a call allocation operation and a call allocation rejection operation, if the overload is detected by the overload detect means; wherein the drive means obtains the thresholds at each point and stores them in the data base right after initializing a system, and the overload detect means compares the overload detect value with the thresholds at each point respectively and concludes the overload when the overload detect value exceeds each threshold.
