Abstract
A user terminal is connected to an IP network through an access gateway, and service provider networks are connected to the IP network through an exchange router and border gateways. A group of servers store, for example, information about users, information about services, information about connection, and account information, and, in addition, perform user accounting and alternative account billing to the users. The exchange router converts a packet from the user terminal to the protocol/format on the service provider side and converts a packet from the service provider side to the protocol/format of the user terminal. By virtue of this construction, a network system and a packet data transmission method can be realized which unify connection between users and a plurality of service providers and unified management of business routine and accounting.
