The Alcatel-Lucent 5780 Dynamic Services Controller (DSC) is a highly scalable, carrier-grade converged platform

that provides the Policy and Charging Rules Function (PCRF) for 3G and 4G wireless networks (as per the

3rd Generation Partnership Program [3GPP] Releases 7, 8, and 9) as well as support for wireline networks.

Product overview

The 5780 Dynamic Services Controller (DSC) is paramount in delivering personalized services while monetizing the service provider’s network with scale and velocity. The 5780 DSC is a 3GPP-certified Policy and Charging Rules Function (PCRF) at its core, supporting 3GPP Releases 7, 8, and 9. The 5780 DSC also supports residential wireline access by offering a RADIUS/Change of Authorization (CoA) interface to the Broadband  Network Gateway (BNG) and the Broadband Remote Access Server (BRAS).

The 5780 DSC is integrated with the 9900 Wireless Network Guardian (WNG), thus enabling Intelligent Traffic Management (ITM). ITM allows service providers to understand the new breed of broadband traffic (i.e., network intelligence) that wireless networks face, while dynamically identifying and addressing anomalous events that could impact the subscriber’s Quality of Experience (QoE).

The 5780 DSC is part of the Alcatel-Lucent Ultimate Wireless Packet Core (UWPC), leveraging a deep understanding of integrating with key, charging and enforcement elements such as the Gateway GPRS Support Node (GGSN) and Packet Data Network (PDN) Gateways (PGWs). The 5780 DSC supports both 3G and 4G deployments and can be deployed simultaneously in wireline environments. The 5780 DSC is managed by the 5620 Service Aware Manager (SAM), which is also used to manage all of Alcatel-Lucent’s packet core elements. The 5780 DSC can be purchased pre-integrated with the UWPC or it can also be easily deployed in a multivendor environment due to its comprehensive support of all major standardized interfaces. Figure 1 shows a network view of the 5780 DSC.

Product detail

The Alcatel-Lucent 5780 DSC is the decision engine that enables the authorization of network resources to be applied to a service data flow (SDF), the gating of packets from specific SDFs, QoS control for specific SDFs, and flow-based per-SDF charging. The 5780 DSC operates throughout the entire lifecycle of the user interaction with the mobile network. It operates during initial User Equipment (UE) attachment, and during the establish-ment of additional resources to support application session establishment, as well as performs dynamic session mod-ification for established sessions. The 5780 DSC also supports a RADIUS/ CoA interface and interacts directly with a BNG or BRAS to provide wireline policy management concurrently with its wireless offering.

The Alcatel-Lucent 5780 DSC’s state-of-the-art decision engine provides wireless and fixed network service providers with the capabilities to map business demands and network constraints into easy-to-manage network policy rules. The decision engine uses a set of pre- defined operator-configured service policies combined with network (device-type, access type, location, intelligence), subscriber (service tier, pre-paid, credit balance, entitlements), system (state, time of day) and applica-tion information (service description, traffic parameters) that it obtains from its various interfaces to maximize the effectiveness of its policy decisions. Once policy decisions are dynamically synthesized by the decision engine, they are formulated into network consum-able rules and sent through the Gx (or RADIUS/CoA) interface to the PCEF/DPI (or BNG/BRAS) where they are instantiated and enforced for per-device per-application data plane treatment.

The Alcatel-Lucent 5780 DSC imple-ments PCRF as per the 3GPP policy and charging (PCC) architecture Releases 7, 8, and 9 and supports all of the standard interfaces defined therein. The 3GPP-defined Rx interface allows interaction with the Application Function (AF), thereby providing detailed service description information from the IP Multi-Media Subsystem (IMS)-based applications. The RESTful and Web Service (WS) interfaces allow Internet-based third-party applications to interact with the 5780 DSC to negotiate the proper treatment of their underlying per-application packet flows. These interfaces are key parts of the Alcatel-Lucent Application Enablement (AE) offering, allowing service providers to break into the value chain that is normally reserved for application and content providers (ACPs). Figure 2 shows a logical architectural view of the Alcatel-Lucent 5780 DSC and the standard interfaces that it supports.

The 3GPP-defined Gx interface allows interaction with the mobile network, which includes a direct connection to the (PCEF) entity on the GGSN, Packet Data Network Gateway (P-GW), or Deep Packet Inspection (DPI) appliance. The Gx interface also provides an indirect connection via the PCEF (from Gy and Gz) to the Online Charging System (OCS) and the Offline Charging System (OFCS), respectively, providing dynamic and seamless per-packet flow charging.

The Sp interface is implemented by the 5780 DSC as the Diameter-based Sh and the Lightweight Directory Assistance Protocol (LDAP) and allows interaction with the Service Profile Repository (SPR). This interaction provides information on the profile of a subscriber who is requesting the service session (including information such as service tier, entitlements, historic data consumption, and other per-subscriber options). This information provides unique subscriber information that is crucial in enabling service personalization.

The interface to the 9900 WNG allows the 5780 DSC to have access to per-device, per-application network intelligence, enabling the solution

ITM. ITM allows service providers to define policies that address anomalous behavior (such as heavy users, security threats) in the network before they become an issue that impacts valued “monetized” subscribers and compro-mises the integrity of the network.

The RADIUS/CoA interface is used to concurrently support wireline network access by interacting with a BNG or legacy BRAS elements to provide policy management in an access-independent manner.

The physical components of the 5780 DSCThe Alcatel-Lucent 5780 DSC is based on the NEBS-certified, carrier-grade Alcatel-Lucent ATCA 14-slot blade server platform. This platform is field proven and is also used for the Alcatel-Lucent 9471 Wireless Mobility Manager (WMM), the Alcatel-Lucent 8650 Subscriber Data Manager (SDM), and other Alcatel-Lucent IMS products. Although this section only describes the Alcatel-Lucent ATCAv2 hardware components, the complete 5780 DSC software is also fully supported on SUN hardware.

The Alcatel-Lucent 5780 DSC uses a single processor blade that can function as the Common Services Blade or for PCRF processing. The Common Services Blade provides the system OAM functions, connectivity to the Alcatel-Lucent 5620 Service Aware Manager (SAM), the Web Console, and the provisioning interface. It also provides and maintains all of the external interfaces, while dispatching (load-balances) requests to the PCRF processing blades. The Common Services Blade is configured in a 1+1 pair for redundancy, and a single pair is required per ATCA shelf. The PCRF processing blade’s core function is the policy-decision engine and it maintains service data-flow states, creates application session bindings, and provides event forwarding. The PCRF processing blade is configured in 1+1 pairs for redundancy, and up to five pairs can be deployed in a single ATCA shelf.

The 5780 DSC shelf also includes the switching hub blade that is used to provide internal communication between processing blades. The switching hub blades are housed in the middle two slots in the chassis and are configured in a 1+1 redundancy pair.
