[. . . ] Alcatel-Lucent 5780 DSC DYNAMICSERVICESCONTROLLER|RELE ASE3. 0 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 decision engine uses a set of predefined 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 application 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 consumable 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 implements 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. 2 Alcatel-Lucent5780DSC|Release3. 0|DataSheet Figure 2.

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 compromises the integrity of the network. [. . . ] 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.
