• Quantum Subscriber Analytics
• Quantum Policy Server implements the Policy and Charging Rules Function (PCRF), which provides real-time management of subscribers, applications, and network resources based on service-provider-configured business rules. The Quantum Policy Server controls and coordinates the subscriber's session across multiple enforcement points in the network, such as gateways, deep packet inspection (DPI) devices, and optimization servers. Policy decisions and enforcement actions include subscriber session authorization, service selection and personalization, quality of service (QoS) and bandwidth control, session- and application-specific quota authorization and tracking, as well as application-based admission control.
• Quantum Charging Server supports both online (OCS) and offline (OFCS) charging services with real-time rating rules. The Quantum Charging Server offers an easily deployed prepaid OCS solution including integration with external intelligent network (IN) systems. One-time, recurring, rollover, and top-up balances are supported, against which both default and user-personalized thresholds (for example, low-balance notifications) may be defined. Quotas may be shared across group accounts, such as family, corporate, or multiple-devices plans. For offline charging, the Quantum Charging Server supports flexible Charging Detail Record (CDR) generation. Rules-based filters can be applied to CDR streams, for example, to strip out nonbilling-related fields or to augment records with data from other sources.
• Quantum Application Gateway extends policy control to the web, allowing web-based, non-IMS applications to take full advantage of the policy framework (for example, to request QoS to sponsor data access or to offer cloud-based services). Applications can be quickly integrated with policy using SOAP/REST-based web services and at reduced costs without the need to support the Rx interface. Deployed at the network edge, the Quantum Application Gateway supports secure access from applications and handsets. Service providers can control which third-party over-the-top (OTT) partners can request policy services through mutual authentication and access control lists.
• Quantum Unified Subscriber Manager is a centralized, highly scalable subscriber data management solution for real-time subscriber policy and charging control. This unique subscriber profile repository (SPR) provides a comprehensive data storage engine coupled with a virtualized bridge to federate existing subscriber databases into a unified access layer. Quantum Unified Subscriber Manager services the Quantum application layer, including Policy Server, Charging Server, and Application Gateway. It can be used as a standalone Subscriber Data Management (SDM) solution, but also smoothly integrates with Cisco Quantum Policy Suite components as well as with other systems.
• Quantum Subscriber Analytics captures essential subscriber event and transaction data that cannot be fulfilled in either the back-office or transport layers. Operators can examine subscriber behavior and usage by time of day, location, network access type, application, session duration, and subscriber events. The Quantum Subscriber Analytics reporting dashboard provides comprehensive graphical reports for both impromptu and scheduled reporting.
A Platform Approach to Policy and Charging Control
• The Cisco Quantum Policy Suite architecture allows simultaneous sessions and transactions per second (TPS) capacity to be independently scaled. This allows Cisco Quantum Policy Suite to be efficiently sized for both high simultaneous sessions with low TPS or low sessions with high TPS, resulting in lower total cost of ownership when compared to traditional PCRF models. Session scalability in traditional PCRFs is typically limited by the supported TPS and the reverse. As soon as sessions are bound to a given processing node, the ability to handle traffic spikes is reduced.
• The Cisco Quantum Policy Suite's virtual architecture supports flexible and cost-effective carrier grade strategies. Virtual instances are spread across multiple blade servers for full hardware and software redundancy within a Cisco Quantum Policy Suite cluster.
– N+1 load sharing redundancy is provided for the Policy Director layer and Quantum Server transactional load.
– 1+1 data replication is provided for Session Manager and Quantum Unified Subscriber Manager data.
– 1+1 redundancy is provided for the Quantum Control Center and Reporting Servers.
Health checks monitor Cisco Quantum Policy Suite virtual instances and processes. If a fault is detected, processes are restarted in place. Should a blade server fail, incoming requests are directed to available virtual instances on other blade servers. This helps to ensure high availability and fault tolerance against software faults as well as hardware failures.
• The flexible nature of the Cisco Quantum Policy Suite lets a service provider go beyond standard policy definition to add new, customized functionality. The Cisco Quantum Policy Suite provides a comprehensive open policy software development kit (SDK) using industry-standard languages and frameworks. Customized or vendor scripting is not needed, which allows service providers to create plug-ins within the existing policy server and automatically exposes the new services to the policy engine.
• Cisco's end-to-end Mobile Internet solutions allow service providers provide high-quality video experiences through their mobile networks, and to monetize and optimize their networks.
• Cisco Services provide technical expertise (including expertise on third-party equipment) across all phases of the network lifecycle, from design, testing, and implementation to network operations.
• Cisco Services are proven to rapidly deliver Mobile Internet solutions, resulting in high-quality voice, data, and video for a powerful customer experience and faster realization of increased revenue and market share.
• Cisco-Services-led deployment accelerates time-to-market and mitigates operational risks with service-level agreements (SLAs).
• Service providers benefit from our cumulative experience across many Mobile Internet solution deployments worldwide.
