METHOD FOR CHARGING CALL UNIT OF PRE-PAID SYSTEM MOBILE PHONE

摘要

PROBLEM TO BE SOLVED: To provide a method for charging call units used by a pre-paid system mobile phone that can transfer remaining call units stored in a telephone card for a public phone to call units for the pre-paid system mobile phone for use of a user without using a card exclusively used for the pre-paid system mobile phone. SOLUTION: A card 2 is inserted and connected to a charge terminal 6, an entry means equipped in the charge terminal 6 designates a desired charge call unit by a user and transmits the call unit to a telephone card management center 5, which authenticates the card 2 and subtracts the call units from the card 2. Then the telephone card management center 5 transfers the resulting call units to a mobile phone call unit management center 4 of the pre-paid system mobile phone to conduct required call unit charging.
