1. A method of triggering a device in a mobile communication system by an apparatus, the method comprising:receiving, by a transceiver of the apparatus, a device trigger request message from an application server, the device trigger request message comprising a priority and a valid period of a device trigger request;
processing the device trigger request based on the priority and the valid period in the device trigger request message;
transmitting, by the transceiver, a subscriber information request message to a home subscriber server (HSS) in response to the device trigger request message;
receiving, by the transceiver, a subscriber information response message from the HSS in response to the subscriber information request message; and
based on the receiving of the subscriber information response message from the HSS, transmitting, by the transceiver, the priority and the valid period via a policy and charging rules function (PCRF) and a packet data network gateway (PGW) to a serving gateway (SGW),
wherein the SGW determines whether to transmit or buffer downlink data packets based on the priority and the valid period upon receipt of the downlink data packets from the application server.
