Abstract:
An operating system (OS) update to a secure element (SE) may be commanded, for example, in order to fix a security bug, upgrade a version of an OS, provide mobile network operator (MNO) specific extensions such as to an application programming interface (API) or to cause OS/profile switching. Many of these OS updates will affect one or more profiles present on the SE. An MNO associated with a given profile will benefit in some instances by being provided with a notification of the OS update, since the OS update may affect SE capabilities and thus affect what a given profile can or cannot do after the OS update occurs. Embodiments provided herein create notification entries that will appropriately inform the concerned MNO. In some embodiments, a capability linking variable (“linkedcapability”) is used to determine whether an SE capability change should trigger transmission of a notification to the concerned MNO.
