Packet transfer scheme using mobile terminal and router for preventing attacks using global address
First Claim
Patent Images
1. A method for operating a portable terminal having a TCP/IP module to communicate packets with a mobile communication network, comprising:
- receiving a router advertisement message from a neighboring router in the mobile communication network, the router advertisement message containing a network prefix to be used for the mobile communication network;
generating a global address by combining the network prefix and a device ID which is assigned to the portable terminal;
transmitting a notify message to the router, the notify message containing the global address generated;
setting up the TCP/IP module to the global address for utilizing the global address in an application on the portable terminal;
transmitting a first message indicating a start of the application using the global address to the router, when a processing of the application is started; and
transmitting a second message indicating an end of the application using the global address to the router, when the processing of the application is ended.

Abstract
In a mobile communication network providing an Internet service, the arrived packets are delivered from the nearest neighbor router device to the mobile terminal device according to the need such as when a prescribed application is activated or when a prescribed packet has arrived, by using message exchanges between the nearest neighbor router device and the mobile terminal device, so that it becomes possible to prevent the unnecessary packet attacks from the global Internet.

6. A method for executing an application on a portable terminal having a TCP/IP module to communicate packets with a mobile communication network, comprising:
-
storing a network prefix assigned by a neighboring router, the network prefix being available to use the mobile communication network, and storing a device ID assigned to the portable terminal; generating a global address by combining the network prefix and the device ID, when activating an application by the portable terminal; transmitting a notify message to the router, the notify message containing the global address generated; setting up the TCP/IP module to the global address; transmitting a first message indicating a start of the application using the global address to the router, when a processing of the application is started; and transmitting a second message indicating an end of the application using the global address to the router, when the processing of the application is completed. - View Dependent Claims (7, 8, 9, 10, 11)
