Abstract: A method and apparatus for maintaining a participation level for a plurality of communication devices assigned to a task group. A server is communicatively coupled to the plurality of communication devices assigned to the task group and defines a minimum quantity of communication devices to be assigned an active executor role for the task group. Communication devices that are assigned the active executor role are locked to the active executor role for the task group when the quantity of communication devices that are currently assigned the active executor role does not exceed the minimum quantity of communication devices to be assigned the active executor role for the task group.

Abstract: The disclosure discloses a method for triggering a Machine Type Communication (MTC) device, where an SGSN/MME receives a trigger from an MTC-IWF, and determines that the MTC device is in an unattached state and the MTC device is in a communication window of the MTC device; when the MTC device gets attached to the network before expiration of the communication window, the SGSN/MME sends the trigger to the MTC device; or when the MTC device fails to get attached to the network before expiration of the communication window, the SGSN/MME sends a trigger transmission report to the MTC-IWF, such that the MTC-IWF saves the trigger by sending the trigger to an SMS-SC, and forwards the trigger transmission report to an MTC server initiating the trigger. The disclosure further discloses a system for triggering an MTC device corresponding to the method. With the disclosure, an MTC device in an unattached state can be triggered.
