COMMUNICATION SYSTEM AND METHOD
First Claim
1. A modem for use at a terminal, the modem comprising:
- first interface apparatus comprising a first wireless transceiver arranged to connect to a wireless cellular network;
second interface apparatus arranged to connect to the terminal; and
processing apparatus configured to perform operations of a wireless cellular modem so as to enable the terminal to access packet-based communications via the second interface apparatus, first interface apparatus and wireless cellular network;
wherein the processing apparatus is arranged to receive at least one first address from the wireless cellular network via the first interface apparatus, the first address being an address of a server of a name-to-address resolution system; and
wherein the processing apparatus is configured to intercept, via the second interface apparatus, a name-to-address resolution query being conveyed from the terminal to the wireless cellular network comprising a second address as a destination address, to translate the second address into the first address, and to retransmit the query to the wireless cellular network via the first interface apparatus with the first address as the destination address so as to access the packet-based communications.

Abstract
A modem is disclosed that, in one embodiment, includes: first interface apparatus comprising a first wireless transceiver arranged to connect to a wireless cellular network; second interface apparatus arranged to connect to the terminal; and processing apparatus configured as a wireless cellular modem for accessing packet-based communications. The processing apparatus is arranged to receive at least one first address from the wireless cellular network via the first interface apparatus, the first address being an address of a server of a name-to-address resolution system. The processing apparatus is further configured to intercept, via the second interface apparatus, a name-to-address resolution query being conveyed from the terminal to the wireless cellular network comprising a second address as a destination address, to translate the second address into the first address, and to retransmit the query to the wireless cellular network via the first interface apparatus with the first address as the destination address.
