Optimization of MTC device trigger delivery
First Claim
1. A mobile communication system, comprising:
- a SCS (Services Capability Server);
a MTC-IWF (Machine Type Communication-Interworking Function);
a HSS (Home Subscriber Server) or a HLR (Home Location Register);
a serving node that is at least one of a MME (Mobility Management Entity), a SGSN (Serving GPRS Support Node), and a MSC (Mobile Switching Center); and
a UE (User Equipment), whereinthe HSS or the HLR generates route information and serving node information,the MTC-IWF receives the route information and the serving node information from the HSS or the HLR, prioritizes the serving node based on usage rate of the serving node, and selects the prioritized serving node, andthe SCS delivers a trigger message to the UE via the selected prioritized serving node.

Abstract
A network node (21), which is placed within a core network, stores a list of network elements (24) capable of forwarding a trigger message to a MTC device (10). The network node (21) receives the trigger message from a transmission source (30, 40) placed outside the core network, and then selects, based on the list, one of the network elements to forward the trigger message to the MTC device (10). The MTC device (10) validates the received trigger message, and then transmits, when the trigger message is not validated, to the network node (21) a reject message indicating that the trigger message is not accepted by the MTC device (10). Upon receiving the reject message, the network node (21) forwards the trigger message through a different one of the network elements, or forwards the reject message to transmission source (30, 40) to send the trigger message through user plane.
