Abstract

Techniques to manage updates for eSIMs of a secondary wireless device are disclosed. Responsive to a user input, expiration of a timer, receipt of a message from an associated primary wireless device, processing circuitry of the secondary wireless device commands an eUICC to update an eSIM. A secure data connection is established between the eUICC and a network provisioning server, either directly from the secondary wireless device to a cellular wireless network or relayed indirectly via the primary wireless device. The eUICC and the network provisioning server exchange messages in accordance with a BIP process to update the eSIM. The eUICC provides a status to the processing circuitry indicating success or failure for the eSIM update. Upon success, a portion of the secondary wireless device may be placed in a reduced power state. Upon failure, the eSIM update process may repeat up to a maximum number of retries.

First claim

1 . A wireless device configured for updating electronic Subscriber Identity Modules (eSIMs) of an embedded Universal Integrated Circuit Card (eUICC) included in the wireless device, the wireless device comprising:
wireless circuitry comprising one or more antennas; the eUICC; and processing circuitry communicatively coupled to the wireless circuitry and external to the eUICC, the processing circuitry comprising one or more processors and a memory storing instructions that, when executed by the one or more processors, cause the processing circuitry to:
perform an eSIM update process that includes:
sending, to the eUICC, a command to trigger an eSIM update applet on the eUICC;
receiving, from the eUICC, a request to establish a secure data connection to a network provisioning server;
establishing the secure data connection between the eUICC and the network provisioning server; and
receiving, from the eUICC, an eSIM update status; and

repeat the eSIM update process until the eSIM update status indicates success or a maximum number of retries occurs.

2 . The wireless device of claim 1 , wherein execution of the instructions further causes the processing circuitry to enter a reduced power state when the eSIM update status indicates success.

3 . The wireless device of claim 1 , wherein the processing circuitry repeats the eSIM update process when the eSIM update status indicates failure.

4 . The wireless device of claim 1 , wherein the secure data connection includes a cellular wireless data connection between wireless device and the network provisioning server.

5 . The wireless device of claim 1 , wherein execution of the instructions further causes the processing circuitry to:
send a request for an eSIM update to the network provisioning server in accordance with a bearer independent protocol (BIP); and receive one or more responses that include the eSIM update from the network provisioning server in accordance with the BIP.

6 . The wireless device of claim 1 , wherein the processing circuitry of the wireless device performs the eSIM update process responsive to receipt of a user-initiated update.

7 . The wireless device of claim 1 , wherein the processing circuitry of the wireless device performs the eSIM update process in response to expiration of an update timer while the wireless device is connected to an external power source.

8 . An apparatus for updating electronic Subscriber Identity Modules (eSIMs) on an embedded Universal Integrated Circuit Card (eUICC) included in a secondary wireless device associated with a primary wireless device, the apparatus comprising:
processing circuitry of the secondary wireless device external to the eUICC, the processing circuitry comprising one or more processors and a memory storing instructions that, when executed by the one or more processors, cause the processing circuitry to:
perform an eSIM update process that includes:
sending, to the eUICC, a command to trigger an eSIM update applet on the eUICC;
receiving, from the eUICC, a request to establish a secure data connection to a network provisioning server;
sending, to the primary wireless device, a request to establish the secure data connection to the network provisioning server; and
receiving, from the eUICC, an eSIM update status; and

repeat the eSIM update process until the eSIM update status indicates success or a maximum number of retries occurs.

9 . The apparatus of claim 8 , wherein execution of the instructions further causes the processing circuitry to enter a reduced power state when the eSIM update status indicates success.

10 . The apparatus of claim 8 , wherein the processing circuitry repeats the eSIM update process when the eSIM update status indicates failure.

11 . The apparatus of claim 8 , wherein the secure data connection includes a cellular wireless data connection between the primary wireless device and the network provisioning server.

12 . The apparatus of claim 11 , wherein the secure data connection further includes a non-cellular wireless data connection between the primary wireless device and the secondary wireless device.

13 . The apparatus of claim 8 , wherein the eUICC of the secondary wireless device is configured to:
send a request for an eSIM update to the network provisioning server in accordance with a bearer independent protocol (BIP); and receive one or more responses that include the eSIM update from the network provisioning server in accordance with the BIP.

14 . The apparatus of claim 8 , wherein the processing circuitry performs the eSIM update process responsive to receipt of a notification from the primary wireless device, the notification indicating availability of an eSIM update for the eUICC.

15 . A wireless device configured for updating electronic Subscriber Identity Modules (eSIMs) on an embedded Universal Integrated Circuit Card (eUICC) included in the wireless device, the wireless device comprising:
wireless circuitry comprising one or more antennas; and the eUICC comprising a processor and a memory storing instructions that, when executed by the processor, cause the eUICC to:
receive, from processing circuitry of the wireless device external to the eUICC, a command to trigger an eSIM update applet on the eUICC;
provide, to the processing circuitry in response to the command to trigger the eSIM update applet, a request to establish a secure data connection to a network provisioning server;
when the secure data connection is established between the eUICC and the network provisioning server, retrieve an eSIM update from the network provisioning server in accordance with a bearer independent protocol (BIP); and
provide, to the processing circuitry, an eSIM update status that includes an indication of whether the eSIM update succeeded or failed.

16 . The wireless device of claim 15 , wherein the secure data connection includes a cellular wireless data connection between the wireless device and the network provisioning server.

17 . The wireless device of claim 15 , wherein secure data connection includes a cellular wireless data connection between a second wireless device associated with the wireless device and the network provisioning server.

18 . The wireless device of claim 17 , wherein the secure data connection further includes a non-cellular wireless data connection between the wireless device and the second wireless device.

19 . The wireless device of claim 15 , wherein retrieval of the eSIM update includes the eUICC of the wireless device:
sending a request for the eSIM update to the network provisioning server in accordance with the BIP; and receiving one or more responses that include the eSIM update from the network provisioning server in accordance with the BIP.

20 . The wireless device of claim 15 , wherein the processing circuitry of the wireless device external to the eUICC repeats triggering of the eSIM update up to a maximum number of retries when the eSIM update status indicates failure.
