SYSTEM FOR SUPPLYING CALL GIFT CERTIFICATE IN MOBILE COMMUNICATION NETWORK AND METHOD THEREFOR

摘要

PURPOSE: A system for supplying a call gift certificate in a mobile communication network is provided to implement call gift certificates online, and to automatically manage usage of the call gift certificates in a wireless terminal accounting server, thereby preventing a risk of loss with an easy-to-use function. CONSTITUTION: A database(110) stores terminal user information and call gift certificate information. A user authenticator(102) confirms whether a call gift certificate user and a wireless terminal user receiving a call gift certificate are legal users in reference to the database(110). A call gift certificate manager(104) manages kinds of call gift certificates stored in the database(110). A call detail manager(106) manages communication service usage details of the wireless terminal user, and transmits the call details to an accounting server.
