Embodiment Construction

[0020] An exemplary communication system according to the present invention includes a wireless terminal, a server belonging to a first network, and an authentication server belonging to a second network different from the first network. For example, the first network may be a wireless LAN or a digital subscriber line network, as well as any other network understood in the art. Additionally, the second network may be a mobile telephone network.

[0021] In this example communication system, a wireless terminal transmits identification information to a server of a first network. For example, the identification information may be stored in memory in the wireless terminal. The memory may be a detachable memory card, such as a Subscriber Identity Module (SIM) card or another type of memory medium. Also, the identification information is not valid in the authentication of the first network, but may be valid in the authentication in a network different from the second network.

Abstract

An authentication method according to the present invention includes transmitting primary identification information from a wireless terminal to a first network; routing the primary identification information from the first network to a second network; performing an authentication by the second network based on the primary identification information; and providing a service of the first network to the wireless terminal based on a result of the authentication by the second network.

Description

technical field [0001] This application claims priority from Japanese Patent Application No. 2004-219458, the contents of which are incorporated herein by reference. [0002] The invention relates to a communication network, a wireless terminal, an access server and an authentication method therefor. technical background [0003] Recently, 3GPP (Third Generation Partnership Project) has promoted standardization on mobile phones equipped with wireless LAN access capabilities (see, for example, "3G Security: Wireless Local Area Network (WLAN) Interworking Security (Release 6), 6 Security Mechanisms (3G Security: Interaction Security for Wireless Local Area Networks (Version 6), 6 Security Mechanisms)” (3GPP TS 33.234 V6.1.0, pp.20-42, June 2004)). [0004] Wireless LAN access standardized by 3GPP generally assumes that a wireless LAN terminal such as a conventional mobile terminal is implemented with a SIM (Subscriber Identity Module) card. Based on the authentication proces...
