The Cisco Quantum Policy Suite for Mobile is a fully virtualized, carrier-grade policy, charging, and subscriber data management solution that allows service providers to rapidly create and bring new services to market, delivering a better user experience, optimizing resource usage, and generating new monetization opportunities.

Working in conjunction with policy enforcement points in the network, the Cisco Quantum Policy Suite for Mobile is a standards-compliant solution for the real-time, dynamic management of subscribers, applications, and network resources based on service provider-configured business rules across third-generation (3G), fourth-generation (4G), and Long Term Evolution (LTE) access networks, and IP multimedia subsystem (IMS) service architectures.

Challenge

The Cisco Visual Networking Index (Cisco VNI) Global Mobile Data Traffic Forecast predicts that between 2013 and 2018, the global mobile IP traffic will increase from less than 18 exabytes to an annual run rate of 190 exabytes. In addition, there will be more than 10 billion mobile-ready devices and connections in 2018, almost 3 billion more than in 2013. Finally, the average mobile connection speed will nearly double, from 1.4 Mbps in 2013 to 2.5 Mbps by 2018.To compete in this rapidly changing environment, mobile service providers need a policy solution that does more than contain network costs. You need a solution that acts as an intelligence layer for mobile data services to provide a personalized and optimized experience for subscribers. Policy is more than Policy and Charging Rules Function (PCRF). It is a platform for service innovation.

Solution

The Cisco Quantum Policy Suite is a comprehensive policy, charging, and subscriber data management solution that helps service providers control and monetize their networks and profit from personalized services.

Figure 1.      Cisco Quantum Policy Suite Solution Architecture

The Cisco Quantum Policy Suite for Mobile provides an intelligent control plane solution. It includes southbound interfaces to various policy control enforcement functions (PCEFs) in the network, along with northbound interfaces to OSS/BSS and subscriber applications, IMSs, and web applications (Figure 1). The Cisco Quantum Policy Suite modules are activated individually or deployed as an integrated end-to-end policy, charging, and service creation solution.

The Cisco® solution includes the following core modules.

   Policy module implements PCRF, which provides real-time management of subscribers, applications, and network resources based on service provider-configured business rules. The Cisco Quantum policy module controls and coordinates the subscriber’s session across multiple enforcement points in the network, including gateways, deep packet inspection (DPI) devices, and optimization servers. Policy control actions include:

     Subscriber session authorization and management

     Service selection and personalization

     Quality of service (QoS) and bandwidth control

     Session- and application-specific quota authorization and tracking

   Charging module supports online charging services (OCS) with real-time rating rules. The Cisco Quantum Charging module offers an easily deployed prepaid OCS solution, including integration with external intelligent network systems. One-time, recurring, rollover, and top-up balances are supported. Both default and user-personalized thresholds (for example, low-balance notifications) may be defined against these balances. Quotas may be shared across groups, such as family, corporate, or multiple-device plans.

Optional Feature Modules

   Subscriber Management

     Centralized, highly scalable subscriber data management

     Real-time subscriber policy and charging control

     Comprehensive data-storage engine, coupled with a virtualized bridge to federate existing subscriber databases into a unified access layer

     Standalone or fully integrated subscriber profile repository (SPR)

   Quota

     Store monetary and usage balances for fair-use caps, bill-shock thresholds, and roaming caps

     Assign multiple recurring, group, and one-time balances to subscribers with a capability for top-up, directly by the subscriber

     Support shared wallet and group accounts in support of family or corporation, or across multiple devices (with separate thresholds per subaccount)

     Track and compare subscriber usage to user-defined thresholds, as set up in the policy rules

     Support subscriber notification, browser redirects, and bandwidth downgrades

   VoLTE

     3GPP Rx interface to IMS voice over LTE (VoLTE) integration

     Voice and conversational video call QoS authorization and control

   External Policy and Charging Integration

     3GPP Sy interface for PCRF integration with an external OCS

     Define policy counters and statuses

     Reference policy counter statuses in policy rules

   External SPR Integration

     Query subscribers from an external subscription profile repository (SPR), Home Subscriber Server (HSS), or provisioning system

     3GPP Sh and Ud interfaces for external SPR integration

     Lightweight Directory Access Protocol (LDAP), SQL, and Diameter integration can be configured in service-definition GUI

Table 1 describes the features and benefits of the Cisco Quantum Policy Suite for Mobile.

A Platform Approach to Policy and Charging Control

To support the fully virtualized solution, the Cisco Quantum core platform underlies the Cisco Quantum Policy Suite for Mobile, and is shared across all Cisco Quantum Policy Suite components (Figure 2). The cornerstone of Cisco’s platform approach is a high-performance core rules engine that delivers exceptional performance. The feature plug-ins of Cisco Quantum Policy Suite for Mobile are a set of componentized feature modules. The core rules engine brings together different feature plug-ins, using policy blueprints, to support use cases that are bundled into product modules. The Cisco Quantum Policy Builder ties the Cisco Quantum Policy Suite components and features together and is used to define new services and policy business rules.

Competitive Benefits

The Cisco Quantum Policy Suite for Mobile provides these benefits over competitive solutions.

   Carrier-Grade Reliability

The Cisco Quantum Policy Suite for Mobile 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. Should a blade server fail, incoming requests are directed to available virtual instances on other blade servers. This helps ensure high availability and fault tolerance against software faults as well as hardware failures.

   Unmatched Scalability

The Cisco Quantum Policy Suite for Mobile scales to support both today's networks and upcoming next-generation networks, such as LTE with VoLTE, which are driving policy transactions per second (TPS) to unprecedented heights. The Cisco Quantum Policy Suite is built to handle high TPS at low latencies. The solution can be sized to fit your network performance requirements and grow with them through the addition of blades in the system, helping to reduce total cost of ownership.

   Service Creation Velocity

The Cisco Quantum Policy Suite for Mobile is purpose-built for rapid solution rollout and extensibility. Prepackaged use case templates are provided to help accelerate time to market. The extensible nature of the Cisco Quantum Policy Suite lets service providers go beyond standard policy definition to support nonstandard, proprietary interfaces and customized service logic without affecting the core platform.
