Policy and charging control method, servers and computer programs therefor

摘要

A policy and charging control method includes creating 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. The first PCC rules are installed 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 by the UE upon activation of a user interface command. The PCRF creates second PCC rules based on the request, and installs them at the PCEF by replacing the first PCC rules by the second PCC rules. The service is continued in accordance with the second PCC rules. PCRF and PCEF servers as well as computer programs are also defined.
