“…The usage of OSA APIs requires some expertise in telecommunications as the level of abstraction of network functions provided is low. Parlay X Web services are intended to provide open service access with more convenient interfaces and greater abstraction of the underlying network and data resources [9]. Parlay X "Application-driven Quality of Service" is a service which makes the available QoS on user connections in the network manageable.…”

The emerging multimedia communications are expected to enable simultaneous services with high throughput and low-latency requirements. Ensuring appropriate quality of service (QoS) for multimedia services is one of the challenges that network operators have to cope with in the Evolved Packet System (EPS). The mechanism which allows policy based authorization and usage control of QoS resources intended for multimedia traffic in EPS is called Policy and Charging Control (PCC). The paper investigates the capabilities for open access to PCC. The open access allows third party applications to access functions in the telecommunication networks through Application Programming Interfaces (APIs). The support of standardized APIs for PCC is evaluated. An approach to design new APIs for PCC is described. APIs implementation issues are addressed including interface-to-protocol mapping. The functional verification of application server for open access to PCC functions is formalized. The application server's functional behaviour is modelled and adaptive load control mechanism is proposed. The application server performance and utilization are evaluated.

This paper deals with the quality of service in IP Multimedia Subsystem networks. The evaluation of Quality o Service (QoS) is done through admission control methods. We analyse various methods, which are based on the traffic measurement. The approach that can be applied in finding the suitable admission control method while considering selected QoS parameters is described. Different important QoS parameters can be defined, however we decided to focus on the loss parameter. In our simulations we have used Simple Sum method. Based on the simulation results, we have used new algorithm. The main difference is that it uses the mechanism of time window for achieving more accurate traffic estimate. Algorithm Measured Sum with implementation of time window T has better ability to predict the traffic fluctuation. Compared to the Simple Sum algorithm it achieves lower link utilisation, but also lower level of loss ratio. *
