Embodiment Construction

[0041] Embodiments of the present invention will be described below with reference to the drawings.

[0042] FIG. 1 is a configuration diagram showing an outline of a system according to an embodiment of the present invention.

[0043] This system is constructed in such a way that it connects the user's CPE5 and the mobile network service provider (MISP) that provides roaming services across the provider of public wireless LAN service (PWC) and the provider of mobile communication service (MCC) 8, and the CPE5 communicates with the connected partner (CN)6. The present system also illustrates roaming services across a provider (PWC) 9 providing a public wireless LAN service and a provider (MCC) 10 providing a mobile communication service, but the provider (PWC) providing a public wireless LAN service and A mobile communication service provider (MCC) is an example of a provider that communicates with a user, and the present invention can also provide roaming services between PW...

Abstract

A roaming service covering a plurality of telecommunications carriers in mobile data communication is provided. In a communication system including a wireless terminal, two or more terminal-side networks communicating with the wireless terminal, and a backbone-side network connected to the terminal-side networks and connecting the wireless terminal with a backbone network, the wireless terminal traveling between the terminal-side networks during communication, wherein each of the terminal-side networks has a relay device for relaying communication between the wireless terminal and the backbone-side network and wherein the backbone-side network has a position management device for managing positional information of the wireless terminal and an authentication device for authenticating the wireless terminal according to contract information of the wireless terminal.

Description

technical field [0001] The present invention relates to a method of providing network services, in particular to a method of providing roaming services among multiple communication providers in data communication across a mobile body. Background technique [0002] In recent years, a hot spot (hotspot), which is an Internet connection service using a wireless LAN (Local Area Network) system, is expanding rapidly. Internet connection services using these wireless LAN systems use wireless LAN systems for access lines used by user terminals, and connect to the Internet from there via existing packet switching networks, Internet service providers (ISPs), and the like. [0003] Figure 27 An example of the configuration of the Internet connection service using the wireless LAN system is shown. When the user terminal (CPE) 5 communicates with a communication partner (CN) 6 located on the opposite side of the Internet 7, it passes through a network 9 operated by a provider that pro...
