Abstract

A receiving service supply method using an ESN(Electronic Serial Number) is provided to be capable of conducting data transmission to an operation server by only using an ESN assigned to a mobile communication terminal, thereby simplifying a number authentication procedure in case of the data transmission. An operation server registers an ESN of a mobile communication terminal(S101), and transmits plural ESNs to an HLR(Home Location Register)(S103). If a data transmission request is received from the terminal(S105), an MSC(Mobile Switching Center) demands authentication by sending the received ESNs to the HLR(S107). The HLR retrieves whether the operation server where the ESNs are registered exists(S109). If so, the HLR extracts an ID number of the operation server to send the extracted number to the MSC(S111). The MSC transmits data received from the terminal to the operation server(S113).
