Method and device for managing euicc profile installation rights

A method performed by a profile server in a wireless communication system, the method comprising:

• receiving, from a server of a communication operator, a remote subscriber identity module provisioning (RSP) procedure preparation request message including information about whether an unsigned command code is to be used for the RSP procedure;
• obtaining identification information of a profile, based on the RSP procedure preparation request message;
• transmitting the identification information of the profile to the server of the communication operator;
• receiving, from a terminal, an RSP request message including information about a command code;
• verifying the information about the command code, based on the identification information of the profile;
• and
• transmitting data about the profile to the terminal, based on a result of the verifying.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• at least one processor configured to:
• transmit, to a local profile assistant (LPA) installed in the terminal, a remote subscriber identity module provisioning (RSP) procedure start request message including information about whether an unsigned command code is to be used;
• control the transceiver to transmit, to a server of a second operator, a command code generation request message including command code generation information, based on the RSP procedure start request message;
• control the transceiver to receive, from the server of the second operator, a command code in response to the command code generation request message;
• verify the command code;
• control the transceiver to transmit, to a profile server of a first operator, an RSP request message including information about the command code, based on a result of the verifying;
• and
• control the transceiver to receive, from the profile server of the first operator, data about a profile, in response to the RSP request message.
