Method of controlling congestion of MTC data in a mobile communication system
First Claim
1. A method of controlling congestion in a mobile communication system, the method comprising:
- receiving, by a core network node, subscription information on terminals and congestion control information from a registration information server;
receiving, by the core network node, an access request from the terminals;
when the access request is received from the terminals, rescheduling, by the core network node, traffic on the terminals in consideration of the received subscription information and congestion control information and a situation of the core network;
generating, by the core network node, a result value of the rescheduling that indicates an allowed time of the terminals, wherein the result value of the rescheduling is a first parameter, and a value of the first parameter is a changed value of a second parameter during the rescheduling of the traffic; and
transmitting, by the core network node, the rescheduled result to the terminals.

Abstract
The present invention relates to a method for controlling traffic congestion of MTC devices in a mobile communication system which provides a machine type communication (MTC) service. The method of the present invention is configured in that a core network node (for example, MME, MSC, SGSN, etc.) performs scheduling and rescheduling procedures on data communication traffic for user equipment (that is, MTC devices) using subscription information and congestion control information of the user equipment; and generates a resultant “recalculated time interval” parameter and transmits the parameter to the user equipment, thereby efficiently distributing the amount of data communication (that is, traffic) concentrated to a specific time slot, and thus controlling traffic congestion or network overload.

7. A method of controlling congestion in a mobile communication system, the method comprising:
-
receiving, by a core network node, subscription information on terminals and congestion control information from a registration information server; receiving, by the core network node, an access request from the terminals; if the access request is received from the terminals and if the access request includes a machine type communication (MTC) device indicator indicating that each of the terminals is an MTC device, rescheduling, by the core network node, traffic on the terminals in consideration of the received subscription information and congestion control information and a situation of the core network; generating, by the core network node, a result value of the rescheduling that indicates an allowed time of the terminals, wherein the result value of the rescheduling is a “
recalculated time interval”
parameter, and a value of the “
recalculated time interval”
parameter is a changed value of an “
allowed time interval”
parameter during the rescheduling of the traffic; andtransmitting, by the core network node, the rescheduled result to the terminals. - View Dependent Claims (8, 9, 10)
