Abstract

Enclosed is traffic processing system and a method of processing traffic. A plurality of apparatuses for processing traffic are provided to disperse traffic for mobile terminals, to prevent the bottle neck phenomenon of the traffic, to effectively process the traffic, and to rapidly use the services of the mobile terminals.

Claims

1. A traffic processing system connected to a radio connection network comprising a plurality of evolved nodes to which mobile terminals are connected to process traffic for the mobile terminals, comprising:

mobility managing apparatuses connected to the plurality of evolved nodes to manage mobility and connection information on the mobile terminals;

a plurality of system architecture gateways for assigning IPs to the mobile terminals in accordance with request of the mobility managing apparatuses and for transmitting data packets for the mobile terminals; and

a load balance unit for transmitting data packets received from an IP network to one of the plurality of system architecture gateways.

2. The traffic processing system of claim 1, wherein the load balance unit stores information on data packets transmitted from a first system gateway to the IP network and information on the first system architecture gateway among the plurality of system architecture gateways and transmits the data packets received from the IP network to the predetermined first system architecture gateway based on the stored information.

3. The traffic processing system of claim 2, wherein the load balance unit transmits data packets to one of the plurality of system architecture gateways by a round robin method when information on the data packets received from the IP network does not exist.

4. The traffic processing system of claim 1, further comprising gateway managing units for transmitting data received from the mobility managing apparatuses to one of the plurality of system architecture gateways.

5. The traffic processing system of claim 4, wherein the gateway managing units transmit data to one of the plurality of system architecture gateways in response to an amount of traffic of the plurality of system architecture gateways.

6. The traffic processing system of claim 1, wherein the plurality of system architecture gateways initialize storage spaces for managing IP addresses using interface IDs and IP prefix information of the mobile terminals when services of the mobile terminals start and, when the mobility managing apparatuses request to assign addresses to the mobile terminals, assign the IP addresses to the mobile terminals using the interface IDs and the IP prefix information of the mobile terminals.

7. The traffic processing system of claim 6, wherein the system architecture gateways compare the IP prefix information on the mobile terminals with the IP addresses of the data packets when the data packets are received from the IP networks and, when the IP prefix information matches the IP addresses, request the mobility managing apparatuses to transmit paging for the data packets.

8. The traffic processing system of claim 7, wherein the system architecture gateways store only a first packet of the data packets during the paging request and, when bearers for the mobile terminals are generated in response to the paging request, transmit the stored first packet to the mobile terminals.

9. A method of processing traffic of a traffic processing system, comprising:

system architecture gateways initializing IP address storage spaces using interface IDs and IP prefix information for the mobile terminals;

receiving address assignment request for the mobile terminals from mobility managing apparatuses; and

assigning IP addresses to the mobile terminals using the interface IDs and the IP prefix information and transmitting the IP addresses to the mobility managing apparatuses.

10. The method of claim 9, wherein, in receiving address assignment request for the mobile terminals from mobility managing apparatuses, address assigning request of the mobility managing apparatuses is distributed by the gate managing units to the system architecture gateways in response to an amount of traffic processed by the system architecture gateways.

11. The method of claim 9, further comprising:

when data packets are received from an IP network to the mobile terminal, comparing the IP addresses of the data packets with the IP prefix information on the mobile terminal; and

when the IP prefix information matches the IP addresses of the data packets, paging for the data packets is requested by the mobility managing apparatuses.

12. The method of claim 11, wherein, in paging for the data packets is requested by the mobility managing apparatuses, only the first packet of the data packets is stored.

13. The method of claim 12, wherein, after paging for the data packets is requested by the mobility managing apparatuses, when a bearer for the mobile terminal is generated by the paging request, transmitting a first packet of the data packets to the mobile terminal.

14. The method of claim 11, further comprising abandoning the data packets when the IP prefix information is not the same as the IP addresses of the data packets.

15. A method of processing traffic of a traffic processing system, comprising:

when a first data packet of a mobile terminal is transmitted to an IP network by a first system gateway among a plurality of system architecture gateways, a load balance unit storing information on the first data packet; and

when a second data packet is received from the IP network to the mobile terminal in response to the first data pack, transmitting the second data packet to the first system gateway in accordance with the stored information.

16. The method of claim 15, wherein, in a load balance unit storing information on the first data packet, information on the first data packet transmitted to the IP network and information on the first system architecture gateway in which the first data packet is processed are stored.

17. The method of claim 15, wherein, when information corresponding to the second data packet does not exist, the second data packet is transmitted to one of the plurality of system architecture gateways by a round robin method.
