Internet connection service method, system, and medium for mobile nodes
First Claim
1. An Internet connection service method for a mobile node comprising:
- receiving an inter-access point protocol (IAPP) message including authentication information on the mobile node from an access point (AP) of a network service area, to which the mobile node currently belongs; and
transmitting the IAPP message to an AP of at least one network service area having different identification information from the network service area, to which the mobile node currently belongs.

Abstract
An Internet connection service method, system, and medium used with mobile nodes. The Internet connection service method, system, and medium can switch a mobile node between network service areas having different extended service set identifiers (ESSIDs) by simplifying a process of re-authenticating a mobile node. The Internet connection service method includes: receiving an inter-access point protocol (IAPP) message containing authentication information on the mobile node from an access point (AP) of a network service area, to which the mobile node currently belongs; and transmitting the IAPP message to an AP of at least one network service area having different identification information from the network service area, to which the mobile node currently belongs.

6. An Internet connection service method for a mobile node comprising:
-
enabling a representative access point (AP) of a first network service area to transmit an inter-AP protocol message (IAPP) message containing authentication information on the mobile node to an IAPP mobility agent server on the Internet if the mobile node is connected to the first network service area;
enabling the IAPP mobility agent server to transmit the IAPP message to a representative AP of at least one network service area having different identification information from the first network service area;
enabling the representative AP of the at least one network service area to multicast the IAPP message to at least one AP in the at least one network service area; and
enabling a first AP in a second network service area among the at least one network service area to perform an authentication process on the mobile node by referring to the IAPP message and to connect the mobile node to the Internet if the mobile node moves to a service area managed by the first AP. - View Dependent Claims (7, 8)

14. A mobile communication base station used in an Internet connection service system for a mobile node, the mobile communication base station comprising:
-
a virtual AP, which is connected to the Internet via a packet data service node (PDSN) and performs an inter-AP protocol operation, the PDSN being connected to a mobile communications network;
a base transceiver station, which is wirelessly connected to the mobile node; and
a communication controller, which obtains authentication information on the mobile node from the virtual AP, and then provides the authentication information on the mobile node to the base transceiver station if the base transceiver station issues a request for the authentication information on the mobile node. - View Dependent Claims (15, 16)

17. A mobile communication base station used in an Internet connection service system for a mobile node, the mobile communication base station comprising:
-
a virtual AP, which is installed in a PDSN and performs an inter-AP protocol operation by using the Internet;
a base transceiver station, which is wirelessly connected to the mobile node; and
a communication controller, which obtains authentication information on the mobile node from the virtual AP and then provides the authentication information on the mobile node to the base transceiver station if the base transceiver station issues a request for the authentication information on the mobile node.

18. An Internet connection service system for mobile nodes comprising:
-
a first AP, which transmits an inter-AP protocol (IAPP) message to the Internet if a mobile node is connected to the Internet in a first network service area;
a second AP, which has a different extended service set identifier (ESSID) from the first AP, receives and stores the IAPP message, and performs an authentication process on the mobile node by referring to the IAPP message stored therein if the mobile node moves to a second network service area; and
an IAPP mobility agent server, which receives the IAPP message from the first AP and then transmits the IAPP message to a representative AP of at least one network service area other than the first network service area. - View Dependent Claims (19)

29. A network for connecting a mobile node to the network, comprising:
-
an authorization, authentication, and accounting (AAA) server coupled to the Internet;
an inter-access point protocol (IAPP) mobility agent server coupled to the Internet; and
a plurality of network service areas coupled to the Internet, wherein;
the mobile node initiates a request for access to the Internet through a first network service area, which accesses the AAA server through the Internet, the AAA server processes the request and permits the mobile node to connect to the Internet;
the first network service area transmits an IAPP message providing information on the mobile node to the IAPP mobility agent server;
the mobile node moves from the first network service area to a second network service area with uninterrupted access to the Internet, and without accessing the AAA server. - View Dependent Claims (30, 31, 32)
