Abstract: PURPOSE: A phone number storing method of a mobile communication switching system is provided to reduce a dangerous condition during driving and increase utilization of a mobile phone in a situation that a memo is not available by receiving a phone number of a called party through a send burst DTMF(dual tone multi frequency) message during a call communication and storing and originating the received phone call after termination of the call. CONSTITUTION: A caller dials a phone number by using a mobile phone, and depresses a transmission key to transmits the phone number to a mobile communication exchange(22). The mobile communication exchange requests an authentication of the caller from an authentication center, processes the call, and forms a speech path between the caller and a callee if the caller is in an idle state(24). The caller and the callee communicate through the speech path(26). The mobile phone determines whether a send burst DTMF message is received from the callee during communication(28). If the send burst DTMF message is received, the mobile phone extracts a phone number from the send burst DTMF message(30). The mobile phone determines whether a call is terminated(32). If the call is terminated, the mobile phone determines whether the extracted phone number is selected to be stored by a user when the call is terminated(34). If the user has selected to store the extracted phone number, the mobile phone stores the phone number for reading it anytime later(36). If the user has not selected to store the extracted phone number, the mobile phone determines whether the user has selected to originate the extracted phone number(38). If the user has elected to originated the extracted phone number, the mobile phone originates a call to the mobile communication exchange(40). The mobile communication exchange processes the call and arranges formation of a speech path between the mobile phone and a callee(42).
