Abstract: Upon transmitting privacy information to an MTC server (20) via a network (30, 40), an MTC device (10) includes in a message a field to indicate whether the message contains the privacy information, such that the network (30, 40) can perform authorization for the MTC device (10) and server (20). When the MTC device (10) needs to keep connection with the network (30, 40), the MTC device (10) switches off the functionality of provisioning the privacy information, such that the MTC device (10) still can communicate with the network (30, 40). Upon the transmission of privacy information in an emergency case, the MTC device (10) further includes in the message a content to indicate that the MTC device (10) is an emergency device, such that the network (30, 40) verifies whether the MTC device (10) can be used or activated in the emergency case. Optionally, a USIM for emergency-use is deployed in the MTC device (10).
