Abstract
A method for authenticating and updating an embedded universal integrated circuit card (eUICC) firmware version includes receiving first information from a terminal device, where the first information includes a target identifier, searching a currently stored event record for a target event record, where a group event identifier in the target event record matches the target identifier in the first information, sending the target event record to the terminal device, where the target event record is used to enable the terminal device to download an eUICC firmware version update package, and updating a firmware version of an eUICC of the terminal device based on the eUICC firmware version update package.
Claims22
A method for updating an embedded universal integrated circuit card (eUICC) firmware version implemented by a subscription manager discovery service (SM-DS), the method comprising:
- receiving first information from a terminal device comprising an eUICC, wherein the first information comprises a target identifier;
- searching currently stored event records for a target event record, wherein a group event identifier in the target event record matches the target identifier, and wherein the group event identifier comprises a first eUICC firmware version and a first issuer identifier;
- and
- sending the target event record to the terminal device to enable the terminal device to download an eUICC firmware version update package.
A method for updating an embedded universal integrated circuit card (eUICC) firmware version implemented by a terminal device comprising an eUICC, the method comprising:
- sending first information to an event management server, wherein the first information comprises a target identifier, and wherein the event management server comprises a subscription manager discovery service (SM-DS);
- receiving a target event record from the event management server, wherein a group event identifier in the target event record matches the target identifier in the first information, and wherein the group event identifier comprises a first eUICC firmware version and a first issuer identifier;
- downloading an eUICC firmware version update package based on the target event record;
- and
- updating a firmware version of the eUICC based on the eUICC firmware version update package.
-42. (canceled)
A terminal device, comprising:
- an embedded universal integrated circuit card (eUICC);
- a transceiver coupled to the eUICC and configured to:
- send first information to an event management server, wherein the first information comprises a target identifier, and wherein the event management server comprises a subscription manager discovery service (SM-DS);
- receive a target event record from the event management server, wherein a group event identifier in the target event record matches the target identifier in the first information, and wherein the group event identifier comprises a first eUICC firmware version and a first issuer identifier;
- a processor coupled to the transceiver and the eUICC and configured to:
- download an eUICC firmware version update package based on the target event record;
- and
- update a firmware version of the eUICC based on the eUICC firmware version update package.
