Abstract
An electronic device with a network subscription is provided. The device comprises an embedded secure element including a subscription identification code for identifying the subscriber, a unique public first device identification code and a unique second device identification code linked to the first code. The embedded secure element is one of a physical and virtual secure element, and the second device identification code can be read with external reader equipment when the device is disconnected from the network. Methods of transferring a network subscription and identifying an electronic device are also provided.
Claims20
An electronic device with a network subscription, the device comprising:
- an embedded secure element including a subscription identification code for identifying the subscriber,
- a unique public first device identification code, and
- a unique second device identification code linked to the first device identification code, wherein
- the embedded secure element is one of:
- a physical and virtual secure element, and
- the second device identification code can be read with external reader equipment when the device is disconnected from the network.
A method of transferring a network subscription from a first electronic device to a second electronic device when the first electronic device is disconnected from the network, the first electronic device comprising:
- an embedded secure element including a subscription identification code assigned by a network operator, a unique public first device identification code, and a unique second device identification code assigned by an authorizing entity;
- wherein the method comprises:
- reading the second device identification code from the first electronic device with external reader equipment,
- sending a request for validation of the second device identification code to the authorizing entity,
- receiving a positive or negative validation from the authorizing entity, and
- in response to a positive validation, sending a request to the network operator to transfer the network subscription to the second electronic device.
A method of identifying an electronic device with a network subscription when the electronic device is disconnected from the network, the electronic device comprising:
- a virtual or physical embedded secure element including a subscription identification code assigned by a network operator;
- wherein the method comprises:
- assigning a public unique first device identification code to the electronic device,
- calculating a unique second device identification code based on the first device identification code,
- assigning the second device identification code to the electronic device so that the second device identification code can be read by external reader equipment when the electronic device is disconnected from the network,
- authorizing an entity to request validation of the second device identification code,
- receiving a request for validation of the second device identification code from the authorized entity,
- validating the second device identification code, and
- sending a positive or negative validation to the authorized entity, thereby identifying the electronic device.
