Patent 7715359 was granted and assigned to Huawei on May, 2010 by the United States Patent and Trademark Office.
A method for realizing metering pulses in Next Generation Network (NGN), which enables an MGC (media gateway controller) to cooperate with an MG (media gateway), so as to realize the metering pulse service. When it is necessary to initiate the charging, the MGC transmits the metering pulse signal to the MG, and then the MG transmits the first metering pulse to the user equipment immediately, and periodically transmits the subsequent pulses according to the Pulse Count and Pulse Interval specified by the signal parameter.
