First Claim
Patent Images
1. One or more non-transitory computer readable media with executable instructions stored thereon that, when executed, cause a machine type communications interworking function (MTC-IWF) to:
- initiate load control of signals received by the MTC-IWF to avoid signaling overload;
receive a device trigger request message comprising a priority parameter from a Services Capability Server (SCS), the device trigger request message to trigger a user equipment (UE) to initiate communication with the SCS;
identify the priority parameter in the device trigger request message;
transmit a subscriber information request;
receive a subscriber information response;
determine whether the SCS is authorized to trigger the UE; and
transmit a device trigger report to the SCS.

8. A user equipment (UE) adapted for machine type communications (MTC) with a Services Capability Server (SCS) in a mobile network, the UE comprising:
-
at least one antenna; and a receiver to receive a device trigger from at least one MTC interworking function (MTC-IWF) to prompt the UE to take an action in response to the device trigger, wherein the SCS is adapted to transmit a device trigger request with a priority parameter to the MTC-IWF for the MTC-IWF to determine; whether to send the device trigger to the UE; and whether the SCS is authorized to request the device trigger for the UE, wherein the MTC-IWF is further adapted to transmit a device trigger report comprising a cause value to the SCS. - View Dependent Claims (9, 10, 11, 12, 13, 14)

- 15. A machine type communications interworking function (MTC-IWF) to communicate a device trigger in a mobile network, the MTC-IWF comprising circuitry to receive a device trigger request comprising a priority parameter from a Services Capability Server (SCS), the SCS to transmit the device trigger request to trigger a user equipment (UE) to take an action in response to the device trigger, wherein the circuitry is further adapted to identify the priority parameter associated with the device trigger request, to determine whether the SCS is authorized to send the device trigger request for the UE, and to transmit a device trigger report to the SCS.
