Abstract:
The present invention faces the issue of authorizing redirection services in PCC architecture and provides for a PCRF server adapted to determine redirection per service in an IP-CAN session, a PCEF device adapted to receive redirection information per service basis, to determine redirection per service request and to trigger the redirection; and a method of authorizing a redirection service in a PCC architecture, comprising: upon an IP-CAN session establishment or modification, a PCEF device requesting control rules; a PCRF server determining services requiring redirection and answering with control rules and redirection information per service basis; installing at the PCEF device the control rules and redirection information; upon a first request for a service, the PCEF device determining the service redirection and returning a redirection message with a redirection identifier; and upon completion of the service redirection, the first request for the service reaching the PCEF, the PCEF verifying the service is authorized and submitting a service allowance towards the service server in charge of the service.

Claim (Index 18):
A Policy and Charging Enforcement Function (PCEF) device for enforcing control rules to authorize a service with a Policy and Charging Control (PCC) architecture, the PCEF device configured to:\n transmit, upon establishment or modification of an Internet Protocol (IP) Connectivity Access Network (IP-CAN) session for a user equipment (UE), a request for control rules to a Policy and Charging control Rules Function (PCRF) server via a transmitter; receive, from the PCRF server via a receiver, control rules per service basis and redirection information for a service that requires a redirection before being authorized, wherein the redirection information includes a service redirection identifier indicating where the UE is to be redirected for the service; install the control rules per service basis and the redirection information for the service that requires the redirection; upon a service request, received from the UE via the receiver, for a destined service identified by a service destination identifier, determine that the destined service corresponds to the service that requires the redirection and return, toward the UE via the transmitter, a redirection message with the service redirection identifier and the service destination identifier; receive again via the receiver, upon completion of the redirection, the service request for the destined service identified by the service destination identifier; verify that the destined service identified by the service destination identifier can be authorized; and transmit, via the transmitter toward a service server handling the destined service, a service allowance message for the service request.
