Abstract:
1. A method of handling device triggering in a network gateway node in a mobile communication system, comprising: receiving a trigger request message from a machine-type communication (MTC) server, wherein the trigger request message is to be delivered to a mobile communication device and used for triggering the mobile communication device to start a MTC service; determining the trigger request message is to be valid when one or more MTC features indicated in the trigger request message are subscribed or activated by the mobile communication device and are supported by a network control node of the mobile communication system, wherein whether the one or more MTC features indicated in the trigger request message are supported by the network control node is determined by checking capability of the network control node for the one or more MTC features; and when the trigger request message is determined to be valid, accepting the trigger request message and forwarding the trigger request message to the network control node, for forwarding the trigger request message to the mobile communication device, thereby triggering the mobile communication device to start the MTC service; and rejecting the trigger request message when the trigger request message is determined to be invalid; wherein when the network gateway node does not have the information about the capability of the network control node for the one or more MTC features, the network gateway node includes the information of the one or more MTC features into the trigger request message.
