A METHOD AND APPARATUS FOR PROFILE DOWNLOADING OF GROUP DEVICES

摘要

The present invention is to provide a safe method for remotely installing universal integrated circuit card (UICC) information of various mobile carriers in an embedded universal integrated circuit card (eUICC) which is a security module built in a terminal through a network. In particular, the present invention relates to a method and device for remotely downloading a profile from a network server to eUICCs of two or more terminals. According to the method and device of the present invention, a profile is not directly downloaded by each terminal through a network server (SM-DP or SM-SR), but a profile is effectively installed in a plurality of terminals.
