Abstract

Disclosed is a user authentication card and a method for preventing data synchronization from being performed if information stored in the user authentication card is the same as that stored when a corresponding user equipment (UE) is powered off. The user authentication card includes a memory area for storing an electronic serial number of a UE, a memory area for storing a command defined for requesting the UE to transmit the electronic serial number and a memory area for storing a command defined for requesting transmission of the stored electronic serial number to the UE. A data synchronization method with a user authentication card in a UE capable of recognizing the user authentication card includes determining whether the user authentication card is recognized when the UE is powered on, reading an electronic serial number from the user authentication card and the read electronic serial number coincides with an electronic serial number of the UE, if it is determined that the user authentication card is recognized and controlling data synchronization to be performed only when it is determined that the two electronic serial numbers do not coincide with each other.

Description

technical field [0001] The present invention relates to a user authentication card and a user equipment (UE) for identifying the user authentication card, more specifically, to a method for data synchronization control between the UE and the user authentication card and a user equipment according to the method authentication card. Background technique [0002] When a mobile phone using the Universal Mobile Telecommunications System (UMTS) scheme or the Global System for Mobile Communications (GSM) scheme and the Subscriber Identity Module (SIM) card, Universal Subscriber Identity Module (USIM) card or removable subscriber When the identification module (RUIM, Removable User Identity Module) card is powered on together, the mobile phone reads the user information from the inserted card, determines whether the user is the correct user, and performs data synchronization. Usually, a card (for example, a SIM card, USIM card or RUIM card) is installed in a...
