METHOD AND APPARATUS FOR CONTROLLING TRAFFIC NEXT GENERATION MOBILE COMMUNICATION SYSTEM
First Claim
1. A method of controlling traffic in a network in a mobile communication system, the method comprising:
- determining whether or not a load state of a cell is greater than a threshold;
determining whether or not User Equipment (UE) capable of Device-to-Device (D2D) communication is present in UEs connected to the cell if, as a result of the determination, it is determined that the load state is greater than the threshold;
performing a D2D communication configuration on the UE capable of D2D communication;
determining whether or not UE capable of handover is present in remaining UEs not capable of the D2D communication; and
performing a handover communication configuration on the UE capable of handover.

Abstract
The present invention relates to a method and apparatus for controlling traffic which can be applied to the next generation mobile communication system. The method includes determining whether or not a load state of a cell is greater than a threshold, determining whether or not UE capable of D2D communication is present in UEs connected to the cell if, as a result of the determination, it is determined that the load state is greater than the threshold, performing a D2D communication configuration on the UE capable of D2D communication, determining whether or not UE capable of handover is present in remaining UEs not capable of the D2D communication, and performing a handover communication configuration on the UE capable of handover. According to the present invention, a signaling overload due to the simultaneous handover of a plurality of UEs or congestion of traffic in a target cell can be prevented.

8. A method of controlling traffic in a network in a mobile communication system, the method comprising:
-
determining whether or not a load state of a cell is greater than a threshold; requesting at least one of information about UE capable of Device-to-Device (D2D) communication, information about UE capable of handover, and information about a state of a neighbor cell from a specific database (DB) if, as a result of the determination, it is determined that the load state is greater than the threshold; receiving at least one of the information about UE capable of D2D communication, the information about UE capable of handover, and the information about the state of a neighbor cell from the DB; determining whether or not UE capable of D2D communication is present in UEs connected to the cell based on the received information about UE capable of D2D communication; performing a D2D communication configuration on the UE capable of D2D communication; determining whether or not UE capable of handover is present in remaining UEs not capable of D2D communication based on at least one of the received information about UE capable of handover and the received information about a state of a neighbor cell; and performing a handover communication configuration on the UE capable of handover. - View Dependent Claims (9, 10, 11, 12, 13, 14)
