Abstract: The invention is a method and system for obtaining connection to a packet data network (14). The invention includes inputting a user request to a first network (10) which requests that the user (12) be authorized for connection to the packet data network through a second network; transmitting from the first network to the second network the user request and an authorization of payment to the second network by the first network for the user's use of the packet data network; transmitting from the second network to the first network authentication information granting the user authentication through the second network to the packet data network; and transmitting the authentication information from the first network to the user which informs the user that authentication to obtain connection to the packet data network has been granted.

Abstract: Apparatus, and an associated method, facilitates authentication of at least a portion of a Bluetooth-based, or other, communication system by a mobile terminal. A manner is provided by which to provide to the network portion of the communication system unique identifiers which identify the Bluetooth transceiver circuitry of the mobile terminal. Once provided to the network portion, authentication procedures by which to authenticate the network portion are carried out.

Abstract: The invention relates to a terminal (A), which comprises at least one network interface card (NIC1, NIC2, NIC3) for setting up a data transmission connection to a communication network (NW1, NW2, NW3, MNW) for packet switched data transmission, and means (PD) for forming packets of the information to be transmitted and for unpacking information from the received packets. The terminal (A) is allocated at least one first address identifying the terminal (A), and at least one data network-specific second address.
