PURPOSE: A corporation billing service method in a mobile communication telephone is provided to offer a service method that a company bears the call charges for the usage of cellular phones only in case that the personnel of the company makes a telephone call to a specific staff or a specific destination phone. CONSTITUTION: A caller accesses a cellular exchange with a general directory number(S50). The cellular exchange forwards the call to a relevant CTI exchange by the connected general directory number prefix(S60). The CTI exchange transfers the caller's terminal number to an authentication server to request authentication(S70). The authentication server confirms whether the terminal is registered in the general directory number, and transfers a result to the CTI exchange(S80). The CTI exchange inquires of the caller about a destination number(S90). The caller inputs the destination number(S100). The CTI exchange transfers the destination number to the authentication server(S110). The authentication server transfers an authentication result to the CTI exchange(S120). In case that the destination number is approved by the authentication server, the CTI exchange requests the cellular exchange to connect the call(S130). A billing server charges the telephone charge according to a call charge rate(S140).
