Abstract

A wireless terminal device which can be connected to a wireless LAN service to which the terminal can be connected without regard to the identifier for specifying a wireless LAN service, a wireless connection method, and a program are provided. A wireless terminal device (100) stores common authentication information (200) that can be verified by a plurality of access points (111 to 113) in common in a common authentication information DB (104) in advance. Before connecting to the wireless LAN, the wireless terminal device repeats a trial in order to be authenticated with respect to the connectable wireless LAN service according to the common authentication information (200) until the connection is made.

Claims

1. A wireless terminal apparatus comprising:

a wireless communication section that performs wireless communication with a plurality of access points connected to a network;

a common authentication information storage section that stores common authentication information that can be authenticated by the plurality of access points in common;

a search section that performs a search of the access points by means of the wireless communication apparatus; and

an authentication trial section that performs an authentication trial vis-à

-vis a connectable access point based on a search result of the search section and the common authentication information.

2. The wireless terminal apparatus according to claim 1, wherein the wireless communication section receives a beacon from the access point and performs communication with that access point.

3. The wireless terminal apparatus according to claim 1, wherein the common authentication information storage section divides wireless LAN setting information held by each access point into service identification information and authentication/security information, and stores the authentication/security information as the common authentication information.

4. The wireless terminal apparatus according to claim 1, wherein the search section extracts service identification information including an ESSID.

5. The wireless terminal apparatus according to claim 1, wherein the authentication trial section performs an authentication trial vis-à

-vis all connectable access points.

6. The wireless terminal apparatus according to claim 1, further comprising a temporary profile storage section that temporarily stores service identification information of a connectable access point searched for by the search section as profile information,

wherein the authentication trial section performs an authentication trial vis-à

-vis a connectable access point based on the profile information and the common authentication information.

7. A wireless connection method comprising:

a step of performing wireless communication with a plurality of access points connected to a network;

a step of storing common authentication information that can be authenticated by the plurality of access points in common;

a step of performing a search of the access points by means of the wireless communication;

a step of temporarily storing service identification information of the searched connectable access points as profile information; and

a step of performing an authentication trial vis-à

-vis a connectable access point based on the profile information and the common authentication information.

8. A program for causing a computer to execute each step of a wireless connection method comprising:

a step of performing wireless communication with a plurality of access points connected to a network;

a step of storing common authentication information that can be authenticated by the plurality of access points in common;

a step of performing a search of the access points by means of the wireless communication;

a step of temporarily storing service identification information of the searched connectable access points as profile information; and

a step of performing an authentication trial vis-à

-vis a connectable access point based on the profile information and the common authentication information.
