The method and system involve a policy server and a service gateway which send messages to one another via a user's network access application program. In one embodiment, the network access application program is an Internet web browser (2). The service gateway receives a network access request from a user and sends an authorization request message regarding the user to a policy server via the user's network application program (4). In one embodiment, the network access request is an Internet web site access request. The service gateway will then, if the policy server grants access, receive from the user's network access application program an authorization granted message regarding the user that was initiated by the policy server (8). The service gateway will then provide the user access to a network such as the Internet (12). The policy server receives an authorization request message from a user's network access application program that was initiated by the service gateway. The policy server processes payment information received from the user and, assuming that the payment information is sufficient, provides an authorization granted message regarding the user to the service gateway via the user's network access application program. |
