A method of authorizing a service with a Policy and Charging Control "PCC" architecture, the method comprising the steps of: - upon establishment (S-100) or modification of an IP Connectivity Access Network "IP-CAN" session with a user equipment "UE", a Policy and Charging Enforcement Function "PCEF" device requesting (S-105) control rules to a Policy and Charging control Rules Function "PCRF" server; - determining (S-110) at the PCRF server control rules to be applied per service basis for the IP-CAN session; - determining (S-115) at the PCRF server, based on redirection policy criteria, those services for which a redirection is required; - submitting (S-120) from the PCRF server to the PCEF device the control rules and redirection information per service basis, wherein the redirection information per service basis includes a service redirection identifier indicating where the UE is to be redirected for the service; - installing (S-125) at the PCEF device the received control rules and redirection information per service basis; - upon a first service request (S-130, S-170) from the UE for a service identified by a service destination identifier, the PCEP device determining (S-135, S-175) that the service requires redirection and returning (S-140, S-180) towards the UE a redirection message with the service redirection identifier and the service destination identifier; - upon completion (S-150, S-190) of service redirection, the first service request for the service identified by the service destination identifier reaching (S-155, S-205) again the PCEF device; - verifying (S-160, S-210) at the PCEF device that the service identified by the service destination identifier can be authorized; and - submitting (S-165, S-215) a service allowance message for the first service request from the PCEF device towards a service server handling the service identified by the service destination identifier. - upon establishment (S-100) or modification of an IP Connectivity Access Network "IP-CAN" session with a user equipment "UE", a Policy and Charging Enforcement Function "PCEF" device requesting (S-105) control rules to a Policy and Charging control Rules Function "PCRF" server; - determining (S-110) at the PCRF server control rules to be applied per service basis for the IP-CAN session; - determining (S-115) at the PCRF server, based on redirection policy criteria, those services for which a redirection is required; - submitting (S-120) from the PCRF server to the PCEF device the control rules and redirection information per service basis, wherein the redirection information per service basis includes a service redirection identifier indicating where the UE is to be redirected for the service; - installing (S-125) at the PCEF device the received control rules and redirection information per service basis; - upon a first service request (S-130, S-170) from the UE for a service identified by a service destination identifier, the PCEP device determining (S-135, S-175) that the service requires redirection and returning (S-140, S-180) towards the UE a redirection message with the service redirection identifier and the service destination identifier; - upon completion (S-150, S-190) of service redirection, the first service request for the service identified by the service destination identifier reaching (S-155, S-205) again the PCEF device; - verifying (S-160, S-210) at the PCEF device that the service identified by the service destination identifier can be authorized; and - submitting (S-165, S-215) a service allowance message for the first service request from the PCEF device towards a service server handling the service identified by the service destination identifier.
