Device trigger recall/replace feature for 3GPP/M2M systems
Embodiments for managing device trigger action requests are generally described herein. The device trigger action requests may include a recall or replacement Device-Action Request. In some embodiments, a Device-Action Request command is received at a network entry point node from an external services capability server with an action type attribute value pair set to indicate a device trigger action request for performing an action on an old device trigger request, the network entry point node determines a status of the old device trigger request from the external services capability server and the network entry point node sends a Device-Action Answer command to the external services capability server with a request-status type attribute value pair to report a status of the old device trigger request in response to the device trigger action request for performing an action on the old device trigger request.
