- a GGSN including a central processing unit and a network interface, said GGSN interconnecting a client device having a unique identifier, and a server hosting a service;
said GGSN configured to connect to a PCRF via said network interface, using a first protocol and a second protocol;
said central processing unit configured to receive a request, via said network interface, for said service from said client device and to determine service characteristics by inspecting said request;
said central processing unit configured to send said unique identifier and said service characteristics to said PCRF using said second protocol;
said central processing unit configured to receive a service policy from said PCRF using said first protocol, said service policy based on said unique identifier and said service characteristics; and

Abstract
A communication system and method is provided that includes a gateway. The gateway interconnects a client device and a server that hosts a service. The gateway is configured to determine the characteristics of service being requested by the client device and to communicate with a policy server in order to determine a policy that is to be applied to the fulfillment of the request for the service, assuming that the policy actually permits the fulfillment of the request.

13. A communication method comprising:
-
receiving a service policy request at a gateway from a client device having a unique identifier, said gateway configured to connect to a policy server using a first protocol and a second protocol; determining service characteristics associated with said request at said gateway; sending said unique identifier and said service characteristics from said gateway to said policy server using said second protocol; receiving, at said gateway, a service profile from said policy server using said first protocol; denying said request if said service profile does not permit said service; and fulfilling said request at said gateway by permitting said client device to connect to said service, said fulfilling performed in accordance with said service policy if said service profile permits said service. - View Dependent Claims (14, 15, 16, 17, 18)
