Server. The latter capability allows support of legacy user devices, but cannot provide new, richer voice
services to the user.
Rel-9 has enhanced this functionality to add support of video media. Also added is an optional service
control channel from the user’s device to IMS that is transparent to the MSC Server. This avoids the need
to update legacy CS networks and allows new services to be developed, but cannot support legacy user
devices.
B.3.4 UICC: ENABLING M2M, FEMTOCELLS AND NFC
With the standardization of one new form factor specifically designed for machine-to-machine (called MFF
with two options [1 and 2] for socketable and embedded machine identity modules), the UICC can now
function in harsh environments defined by higher temperature, vibration, and humidity constraints that are
supported by the new form factor and that were not suitable to the 2FF (a/k/a plug in) or 3FF (a/k/a
microSIM) form factors.
The role of femtocell USIM is increasing in provisioning information for Home eNodeB, the 3GPP name
for femtocell. USIMs inside handsets provide a simple and automatic access to femtocells based on
operator and user-controlled Closed Subscriber Group list.
In addition to the files, the USIM is also granted a new USAT interface that will enable UICC applications
to receive the notification when the UE attaches to the femtocells. Such a feature will enable UICC
application to automatically notify the primary UE user or other users of the attachment to a femtocell.
Another USAT feature allows the UICC to discover surrounding femtocells. This will allow MNO to localize
the subscriber or help customer service to troubleshoot femtocell set up issues. The operator can now
forbid access to user-preferred femtocells and restrict access to operator-preferred femtocells, thanks to
UICC parameters.
The upcoming releases will develop and capitalize on the IP layer for UICC remote application
management (RAM) over HTTP or HTTPS. The network can also send a push message to UICC to
initiate a communication using TCP protocol.
Rel-9 is also endorsing the NFC standards by adopting newer releases of SWP and HCI that further
define the behavior of NFC applications located in the NFC UICC according to the NFC architecture
promoted by the GSMA.
Finally, the In Case of Emergency (ICE) files initiated in Rel-8 were completed by a picture file that will
help first responders to identify the victim as the owner of the UE.
