ABSTRACT:
This disclosure concerns systems and methods for network communications. In one example, the method includes: providing subscriber terminals of each network with a respective publicly-known telephone number for allowing communications to be addressed to each subscriber terminal; associating selected subscriber terminals of each network together in a group such that those subscriber terminals can address communications to one another using a respective code allocated to each of the selected subscriber terminals; and, maintaining a database of the codes and corresponding publicly-known telephone numbers of all of the networks and providing to one of the networks a publicly-known telephone number corresponding to a code of a subscriber terminal of another one of the networks to allow communication from a subscriber terminal of one of the networks to be addressed to a subscriber terminal of the other of the networks using the code of the latter subscriber terminal.
