In what environment is the SM-DP used?
The SM-DP is used in a Machine to Machine (M2M) environment.
What is the function of the SM-DP?
The function of the SM-DP is to:
- Take raw profile information from an MNO.
- Personalize it with the appropriate IMSI / Ki pair.
- Convert it to a form suitable for transmission by the SM-SR.
What are the steps for a profile download in an M2M environment?
The steps for a profile download in an M2M environment are:
- An SMS message is sent to eUICC by the SM-SR via the SMSC of the provider of the provisioning profile in order to trigger a session.
- The eUICC requests that the device sets up a data session using Bearer Independent Protocol (BIP) and the URL / IP address of the SM-SR contained in the SMS.
- A CAT_TP or HTTPS transport link is established between the eUICC and the SM-SR.
- A secure channel is established between the SM-DP and eUICC.
- A profile download is initiated by the SM-DP.
