Abstract (en)
[origin: WO2004012413A1] There is disclosed a method and system for enabling authorised-server initiated Internet communication between a client device and a server device by way of an authorisation portal. When the server wishes to initiate a Internet communication with a particular client, the server sends an Internet message to the authorisation portal. The authorisation portal then relays the message to the client device by way of a communications protocol other than the Internet, for example SMS. The client, upon receipt of the message, then establishes an Internet connection to the server. In this way, a server can initiate Internet communication with a client despite the presence of NAT or firewalls or the like that would otherwise prevent server initiated communication.
