Account data by which an access point authenticates a communicating apparatus is stored in a detachable memory device. After the account data stored in the detachable memory device was updated on the communicating apparatus side, when the detachable memory device is attached to the access point, the access point discriminates whether the account data has been updated or not. If it has been updated, the account data stored in a memory of the access point is rewritten to the updated account data. After that, the authentication of the communicating apparatus is made by using the updated account data.
An access point for making access control of a communicating apparatus, comprising:
A communicating apparatus comprising:
A system having an access point for making access control of a communicating apparatus and said communicating apparatus, wherein
A control method for an access point having an authentication server function for authenticating a communicating apparatus on the basis of account data stored in a memory, comprising:
A control method for a communicating apparatus having an interface to attach a detachable memory device in which account data that is used when an access point having an authentication server function authenticates the communicating apparatus has been stored, comprising:

1. Field of the Invention
The invention relates to an access point, a communicating apparatus, a system, and their control method, which are suitable in the case where the communicating apparatus having a communicating function such as wireless LAN (IEEE 802.11), Bluetooth, or the like is authenticated and establishment of a network which takes into consideration security is realized.
2. Related Background Art
FIG. 1 a conceptual diagram showing a construction of a network system according to the first embodiment of the invention;
FIG. 2 is a block diagram showing an internal structure of an access point according to the first embodiment;
FIG. 3 is a flowchart showing processing contents of an account creating program according to the first embodiment;
Prior to explaining details of embodiments of the invention, first, objects to be realized in the embodiments of the invention will be mentioned. In the embodiments of the invention, when a PAN (Personal Area Network) according to a client device in which the IEEE802.1x authenticating and encrypting system such as a Windows (registered trademark) platform or the like has been installed is established by wireless communication, the safe and flexible PAN can be easily established. When the PAN is established, wireless communicating means to be used is enabled to be easily selected. A plurality of wireless communicating means which are used upon establishment of the PAN are enabled to be simultaneously used and a PAN constructed by the different wireless communicating means to be easily established. The number of clients that can participate in the PAN is increased.
In the case where the PAN established by the wireless communicating means is connected to a basic network such as Intranet, Internet, or the like, illegal accesses are mutually inhibited. Costs, which are required in the case of making a product of the present access point are reduced. Upon establishment of the PAN, flexible participation such as temporary participation of the clients, participation by agents, or the like is permitted. The clients who participate in the PAN are concentratedly connected to the access point and client management can be integratedly executed by the present access point. The clients who participate in the PAN are selectively connected to a wireless communication extension card in the access point and management such as client distribution or the like can be realized by the present access point. Management regarding detachable non-volatile memory devices for account management is made easy.
Account data at the time of constructing the PAN by using the access point can be locally and flexibly created. Management of the clients and PAN establishment time can be flexibly made. When a plurality of PANs are established by using a plurality of access points or inserting a plurality of wireless communication extension cards into the access point, the client of each PAN is automatically connected to the access point corresponding to each PAN. If a plurality of accounts for PAN establishment is provided for the access point, the account for the PAN to be established is automatically discriminated and the PAN is established.
