Abstract
A method is provided for performing a management of a multi-subscription SIM module. The multi-subscription SIM module includes at least one memory adapted to store at least a first and a second profile associated with a respective first and a second mobile network operator. The memory includes a volatile portion. The operation of storing includes installing or updating profiles by downloading one or more downloaded profiles from a remote host. The management includes selecting one or more enabled profiles including an application to be executed and allocating a partition of the volatile portion of the memory to the one or more enabled profile.
Claims20
A method for enabling a user profile in a multi-subscription SIM module comprising a memory, the memory comprising a first memory partition and a second memory partition, the method comprising:
- establishing a first connection between the multi-subscription SIM module and a base station using a first user profile allocated to the first memory partition, wherein the first user profile comprises an enabled user profile of the multi-subscription SIM module;
- establishing a second connection between the base station and a remote host;
- downloading, from the remote host via the first connection and the second connection, a second user profile or an update thereof to the multi-subscription SIM module;
- accessing, while downloading the second user profile, the second memory partition, while maintaining the first memory partition as being non-accessible to the second user profile or the update thereof;
- allocating the second memory partition to the second user profile or the update thereof;
- and
- enabling the second user profile as the enabled user profile of the multi-subscription SIM module.
A system, comprising:
- a remote host;
- a base station configured to establish a connection with the remote host;
- and
- a device comprising a multi-subscription SIM module, wherein the multi-subscription SIM module comprises a memory comprising a first memory partition and a second memory partition, the multi-subscription SIM module being configured to:
- establish a connection with the base station using a first user profile allocated to the first memory partition, wherein the first user profile comprises an enabled user profile of the multi-subscription SIM module;
- download, from the remote host, a second user profile or an update thereof to the multi-subscription SIM module;
- access, while downloading the second user profile, the second memory partition, while maintaining the first memory partition as being non-accessible to the second user profile or the update thereof;
- allocate the second memory partition to the second user profile or the update thereof;
- and
- enable the second user profile as the enabled user profile of the multi-subscription SIM module.
