Abstract

In this paper we present an analysis on Policy and Charging Control (PCC) functions in all IP-based multimedia networks and identify the required functionality for quality of service (QoS) monitoring. The support of "Application-driven Quality of Service" (ADQ) Parlay X Web Service to reporting function in PCC is evaluated and improvements of ADQ interfaces are suggested without violating the interface functionality. The gateway which provides Parlay X interfaces for third party applications supports Session Initiation Protocol (SIP) towards the network. A new SIP event package is suggested to support monitoring of QoS provided on SIP sessions.
