Claim of US Patent No. 10,117,220

1. A method for performing machine type communication (MTC) device authentication and triggering, performed by an MTC interworking function (MTC-IWF), the method comprising:on a condition an Internet protocol (IP) connection does not exist between a services capability server (SCS) and an MTC device, receiving from the SCS over a Tsp interface, a device trigger message towards the MTC device, wherein the device trigger message includes a cryptographic key and the device trigger message has an associated level of urgency;
determining a level of network congestion;
transmitting the device trigger message, including the received cryptographic key, to the MTC device in accordance with the associated level of urgency;
sending a report, to the SCS, associated with the determined level of network congestion, wherein the report indicates either success or failure of the device triggering; and
establishing a secure IP connection using the received cryptographic key.
