Abstract
The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a base station in a wireless communication system may comprise a control signal processing step comprising the steps of receiving a first control signal being transmitted from the base station, processing the received first control signal, and transmitting, to the base station, a second control signal generated on the basis of the processing.
Claims15
A method performed by an in-factory profile provisioning (IFPP) server in a communication system, the method comprising:
- obtaining, from a manufacturer server of an embedded universal integrated circuit card (eUICC), encryption key information on each of a plurality of eUICCs;
- transmitting, to a profile provisioning server, a request message for requesting a bound profile package (BPP) for at least one eUICC among the plurality of eUICCs based on the encryption key information,, the request message including encryption key-related information on each of the at least one eUICC;
- and
- receiving, from the profile provisioning server, a response message including the BPP based on the request message,
- wherein the encryption key-related information includes information associated with an algorithm used for generating a temporary key for each of the at least one eUICC, and
- wherein the BPP transferred from the IFPP server via an application of a corresponding terminal is installed in an eUICC of the corresponding terminal.
A method performed by a profile provisioning server in a communication system, the method comprising:
- receiving, from an in-factory profile provisioning (IFPP) server, a request message for requesting a bound profile package (BPP) for at least one embedded universal integrated circuit card (eUICC), the request message including encryption key-related information on each of the at least one eUICC;
- generating the BPP based on the encryption key-related information;
- and
- transmitting, to the IFPP server, a response message including the BPP,
- wherein the encryption key-related information includes information associated with an algorithm used for generating a temporary key for each of the at least one eUICC, and
- wherein the BPP is installed in an eUICC of a corresponding terminal via the IFPP server.
An in-factory profile provisioning (IFPP) server in a communication system, the IFPP server comprising:
- a transceiver;
- and
- a controller configured to:
- obtain, from a manufacturer server of an embedded universal integrated circuit card (eUICC), encryption key information on each of a plurality of eUICCs,
- control the transceiver to transmit, to a profile provisioning server, a request message for requesting a bound profile package (BPP) for at least one eUICC among the plurality of eUICCs based on the encryption key information,, the request message including encryption key-related information on each of the at least one eUICC, and
- control the transceiver to receive, from the profile provisioning server, a response message including the BPP based on the request message,
- wherein the encryption key-related information includes information associated with an algorithm used for generating a temporary key for each of the at least one eUICC, and
- wherein the BPP transferred from the IFPP server via an application of a corresponding terminal is installed in an eUICC of the corresponding terminal.
A profile provision server in a communication system, the profile provisioning server comprising:
- a transceiver;
- and
- a controller configured to:
- control the transceiver to receive, from an in-factory profile provisioning (IFPP) server, a request message for requesting a bound profile package (BPP) for at least one embedded universal integrated circuit card (eUICC), the request message including encryption key-related information on each of the at least one eUICC,
- generate the BPP based on the encryption key-related information, and
- control the transceiver to transmit, to the IFPP server, a response message including the BPP,
- wherein the encryption key-related information includes information associated with an algorithm used for generating a temporary key for each of the at least one eUICC, and
- wherein the BPP is installed in an eUICC of a corresponding terminal via the IFPP server.
