Consumer RSP architecture,
Here’s a quick overview of its key components.
eUICC – This is a secure element that contains one or more profiles. Each profile enables the eUICC to function in the same way as a traditional removable SIM.
Subscription Management Data Preparation Plus, or SM-DP+ for short, is responsible for the profile creation, download, remote management and the protection of the operator’s credentials.
Local Profile Assistant or LPA – is a set of functions in the device responsible for providing the capability to download encrypted profiles to the eUICC. It also presents the local management interface to the user so they can manage the status of profiles on the eUICC.
The discovery service provides a means to notify the LPA when profile data is available for download to the eUICC. The device polls the SM-DS for notifications when required.
