A CHARGING SYSTEM FOR CALLS BETWEEN WIRED TELEPHONES ON THE WIRED TELEPHONE COMMUNICATION SYSTEM BY MEANS OF WIRELESS COMMUNICATION MODULES AND THE METHOD FOR THE SAME

摘要

A charging method for communication between the wired telephone including the steps of start time checking step which checks start time of communication between the wired telephone and object wired telephone, finish time checking step which checks finish time of communication between the wired telephone and object wired telephone, communication time measuring and storing step which measures communication time between the start time and the finish time and stores the communication time with respect to the wired telephone, searching step which searches the wireless communication modules to find out resting wireless communication module, communication time data delivering step which delivers the communication time data with respect to the wired telephone to the found resting communication module, and communication time transmitting step in which the wireless communication module to which the communication time data is delivered transmits the communication time data with respect to the wired telephone to common carrier.
