METHOD FOR USING PLURAL MOBILE COMMUNICATION TERMINALS WITH ONE MOBILE PHONE NUMBER IN MOBILE COMMUNICATION NETWORK, CONCERNED WITH REDUCING COST BY ONLY PAYING THE COST FOR ONE MOBILE PHONE AND PREVENTING UNNECESSARY MOBILE PHONE NUMBERS

摘要

PURPOSE: A method for using plural mobile communication terminals with one mobile phone number in a mobile communication network is provided to register plural mobile communication terminal numbers and position information in a profile of a terminal user, which is stored in an HLR(Home Location Register), and to physically use other plural terminals with one mobile phone, thereby reducing cost by only paying the cost for one mobile phone and preventing unnecessary mobile phone numbers. CONSTITUTION: A system adds a mobile communication terminal information field, a field for registering ESNs(Electronic Serial Numbers) of plural terminals, and a field for storing position information of each ESN to a profile of a terminal user, which is stored in an HLR(S100). The system registers position information of the first mobile communication terminal in a position information field corresponding to the ESN of the first terminal(S200). The system registers position information of an additional terminal having the same ESN as the first terminal in a position information field corresponding to the ESN of the additional terminal(S300).
