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.
