US 2006/0135124 A1 · Unitary management authentication device

Abstract

Respective location information of wireless terminal apparatuses 30-1 to 30-4 and service area information of each of wireless LAN networks 2-1 to 2-n is managed, and authentication information is notified to authentication apparatus 20 of a wireless LAN network before each wireless terminal apparatus moves to the wireless LAN network around the current location of the wireless terminal apparatus. The authentication time is thus shortened in migration inside the same wireless LAN network or between different wireless LAN networks of the wireless terminal apparatus, thereby reducing the interval required for handover, and as a result, quality deterioration does not occur such as packet loss due to the handover.

Dependent claims

A centralized management authentication apparatus that performs centralized management of authentication to enable a wireless terminal apparatus to perform roaming on a plurality of wireless networks each having at least one radio base station, comprising:

an information acquirer that acquires service area information of each of the plurality of wireless networks and information of a current location of the wireless terminal apparatus;
an authentication information notification destination searcher that specifies at least one of the wireless networks that provides communication services in a peripheral area of the current location of the wireless terminal apparatus based on the acquired service area information and information of the current location;
and
an authentication information manager that notifies authentication information required for authentication of the wireless terminal apparatus to the at least one of the wireless networks specified in the authentication information notification destination searcher before the wireless terminal apparatus moves to the at least one of the wireless networks.

1 more element

An authentication apparatus comprising:

an authentication information holder that holds authentication information obtained by making a request for authentication information to a centralized management authentication apparatus that performs centralized management of authentication in movement to each of a plurality of wireless networks of a wireless terminal apparatus;
and
an authentication performer that uses the authentication information held in the authentication information holder in authentication of the wireless terminal apparatus in a service area of a movement destination when the wireless terminal apparatus moves between service areas of a wireless network to which the authentication apparatus belongs.
