Method for coupling a wireless terminal to a data transmission network and a wireless terminal
First Claim
1. A terminal (A) comprising:
- 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 protocol-driver means (PD) for forming packets of information to be transmitted and for unpacking information from received packets, whereinthe terminal (A) is allocated at least one first address identifying the terminal (A) and at least one data network-specific second address, the protocol-driver means (PD) comprising connecting means for connecting the first address to the packets, and the terminal (A) also comprises a network interface selection driver (NISD) to enable the terminal to communicate selectively via any one of a plurality of communication networks, which contains selecting means for selecting the communication network (NW1, NW2, NW3, MNW) to be used in data transmission, transmitting means for transmitting packets between the protocol-driver means (PD) and the network interface card (NIC1, NIC2, NIC3) corresponding to the data transmission network (NW1, NW2, NW3, MNW) selected by the selecting means, and modifying means for modifying the first address according to the data transmission network being used in the packets.

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. The means (PD) for forming packets comprise means for connecting the first address to the packets, and the terminal (A) also comprises a network interface selection driver (NISD), which contains means for selecting the communication network (NW1, NW2, NW3, MNW) used in data transmission at a given time, means for transmitting packets between the means (PD) for forming packets and the network interface card (NIC1, NIC2, NIC3) corresponding to the data transmission network (NW1, NW2, NW3, MNW) used at a given time, and means for modifying the first address to the second address according to the data transmission network used in the packets at a given time.
