Scott Poretsky has been leading implementation of innovative telecommunication products for more than 10 years. Currently, as NextPoint Networks’ Director of Carrier Network Engineering, Scott collaborates with industry for deployment solutions to deliver FMC and IMS services. Scott is currently Technical Co-Chair of the IMS Forum and a participant on the IEEE ComSoc Committee for Quality and Reliability (CQR).

The IMS 3GPP provides an architecture framework for implementing policy enforcement and delivering advanced multimedia and communication services. IPgallery will describe the architecture concepts while providing realistic examples for advanced multimedia and communications use-cases and their derived network implications.

In the ever growing messaging space, end users and regulatory expectations are becoming more and more complex. This evolution has created mandates for the service providers and carriers to implement effective control and screening policies enforcing capabilities to ensure security and the quality of the users' experience. This presentation will discuss policy framework and service screening in order to provide services that meet end user and regulatory requirements.

There are many pre- and post-release 7 policy challenges with implications on fixed, wireless, and cable IMS networks. This session will also cover architecture, protocols and interfaces related to policy and charging, static and dynamic policy issues, charging issues, as well as the evolution from Policy Decision Function (PDF) to Policy and Charging Rules Function (PCRF).

The IMS architecture includes a Policy and Charging Control (PCC) architecture which enables the operator to control the network. This control is necessary as the new IP-based services that are rolling out like IPTV and video streaming will put new demands on the network that require policies for QoS, mobility, and entitlements. The operator needs a policy framework that can be applied across all services, for all subscribers, and for all access networks. This presentation will show how the PCC architecture is being implemented and how it helps operators optimize their monetization of these new services while preventing abuse as well as providing an enjoyable subscriber experience for all customers.

Many discussions of the use of policy focus on signaling aspects and admission control decisions. However, in order for these to be effective, the policy must be enforced in the Media Layer. Otherwise policy decisions can become far removed from the reality of what is occurring in the network. This talk focus the applications of policy-based media control as implemented in the TISPAN Border Gateway Function (BGF) and differentiates enforcement at the TISPAN Resource Control Enforcement Function and Layer 2 Termination Function.

IMS introduces an opportunity for traditional operators to implement IP-based services without sacrificing quality, security, and revenues. However, while IMS defines the architecture and the framework from which operators should implement SIP-based networks, there is still a need for Policy, Control, and Decision to ensure they have complete control over their networks. This presentation looks at the areas that operators should focus on when implementing SIP for the first time, and how to ensure that policies for today are able to migrate to a full IMS architecture.

Due to different delay and packet loss characteristics of the network there is a hard requirement for the Policy Engines to enforce rules independently for the upstream and downstream directions. Policy Engines are split into two virtual engines: the Policy Decision Engine (PDE) and the Policy Enforcement Engine (PEE). The Policy Decision Engine exhibits a quasi-dynamic behavior, intrusively participating in the session control while reserving, modifying and removing resources. The Policy Enforcement Engine is a complex implementation as it has to work under hardcore, real-time constraints. Over and above, the Policy Management functions, on the whole, need to satisfy the deployability aspects of flexibility, scalability, speed and reliability.

This control is necessary as the new IP-based services that are rolling out like IPTV and video streaming will put new demands on the network that require policies for QoS, mobility, and entitlements.

This presentation will explore various ways in which service providers can exploit Bandwidth Management (BWM), Policy Management and Deep Packet Inspection (DPI) in the context of Application Driven QoS (ADQ) Services using Service Delivery Platform (SDP) architectures for IMS deployment. One of the key aspects of the presentation will be to explore ways of enabling composite applications and services that have Policy based ADQ services at its core for IMS based deployments without breaking net neutrality principles.

IMS provides the framework for delivery of rich services over multiple access domains and devices. Operators have to consider various aspects of session mobility across their 2G, 3G and IMS network to offer seamless end user experiences. We will describe various types of mobility available including virtual call continuity (VCC) and Inter-Device mobility. We shall also describe the upcoming standards for IMS Centralized Services which enable delivery of IMS services over legacy devices. The breakout teams will then interact to determine the impact of Policy control on Mobility and vice versa. The objective of this session is to understand how mobility policies can be implemented in the network.
