POLICY AND CHARGING CONTROL METHOD, SERVER, COMPUTER PROGRAM AND USER TERMINAL THEREFOR

摘要

A policy and charging control method includes creating (12) by a policy and charging rules function (PCRF), first policy and charging control (PCC) rules at establishment of a user plane session associated with the UE (300). The first PCC rules are installed (14) at a policy and charging enforcement function (PCEF) and the service is initiated in accordance with these rules. During the lifetime of the user plane session, a quality-of-service (QoS) change request is transmitted (21) by the UE (300) upon activation of a user interface command. The PCRF creates (22) second PCC rules based on the request, and installs (24) them at the PCEF by replacing the first PCC rules by the second PCC rules. The service is continued (26) in accordance with the second PCC rules. PCRF servers, PCEF servers and user terminals as well as computer programs are also defined.
