Cisco Policy Suite for Mobile is an industry-leading carrier policy solution. It is a fully virtualized, carrier-grade policy, charging, and subscriber data management solution, deployable in Network Functions Virtualization (NFV) architectures. The solution allows service providers to rapidly create and bring new services to market, deliver a better user experience, optimize resource usage, and generate new monetization opportunities.

Working in conjunction with policy enforcement points in the network, Cisco Policy Suite for Mobile is a standards-compliant solution for the real-time, dynamic management of subscribers, applications, and network resources.
It uses network, session and subscriber data to deliver subscriber-centric services based on service provider-configured business rules across third-generation (3G) and LTE access networks, as well as IP multimedia subsystem (IMS) service architectures.

Challenge

The Cisco Visual Networking Index (Cisco VNI) predicts that, by 2019, global mobile IP traffic will increase from 30 exabytes in 2014 to 292 exabytes per year. There will be more than 11.4 billion mobile-ready devices and connections, almost three billion more than in 2014. The average mobile connection speed will increase more than 2.4-fold, from 1.7 Mbps in 2014 to 4.0 Mbps by 2019. To compete in this rapidly changing environment, mobile operators need a policy solution that does more than contain network costs. You need to go beyond a traditional Policy and Charging Rules Function (PCRF), with a solution that can act as an intelligence layer for mobile data service innovation. That way, you can provide a personalized and optimized experience for your subscribers.

Solution

Cisco® Policy Suite for Mobile provides intelligence to the control plane, managing session, and subscriber state at scale. It interfaces southbound to various policy control enforcement functions (PCEFs) and IP Multimedia Subsystems (IMS) in the network. It integrates northbound to operation support systems and business support systems (OSS/BSS), subscriber applications, and web applications (Figure 1).

Cisco Policy Suite provides the resource management and orchestration intelligence to dynamically scale your policy solution to adapt to real-world traffic patterns and business growth, helping to reduce capital expenditures (CapEx) and operating expenses (OpEx). With an NFV model, Cisco Policy Suite instances can be deployed in a fraction of the time compared to traditional policy hardware architectures.

Cisco Policy Suite Components

The core modules of Cisco Policy Suite for Mobile can be used individually or deployed as an integrated end-to-end policy, charging, subscriber-management, and service-creation solution.

The Policy Module implements PCRF, which provides real-time management of subscribers, applications, and network resources, based on service provider-configured business rules. 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

The Charging Module supports online charging services (OCS) with real-time rating rules. The Cisco Charging Server offers an easily deployed, prepaid OCS solution, including integration with external intelligent network systems. One-time, recurring, rollover, and top-up balances are supported, against which both default and user-personalized thresholds may be defined. Quotas may also 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

Service Provider Benefits

Cisco Policy Suite for Mobile provides the following benefits.

   Carrier-Grade Reliability

Carrier-grade reliability, high availability, and fault tolerance with a virtual architecture that supports flexible, cost-effective carrier-grade strategies and a smooth transition into an NFV deployment environment. Virtual instances are spread across multiple blade servers for full hardware and software redundancy within a Cisco Policy Suite for Mobile cluster. If a blade server fails, incoming requests are directed to available virtual instances on other blade servers. This helps ensure high availability and tolerance against both software faults and hardware failures.

   Unmatched Scalability

Get increased scalability to support today’s networks and upcoming next-generation networks, such as LTE with VoLTE, which are driving policy transactions per second (TPS) to unprecedented heights. Cisco Policy Suite for Mobile is built to handle high TPS at low latencies. The solution can be sized to fit your network performance requirements. And it supports growth with the addition of virtual instances, for a lower total cost of ownership, compared to traditional PCRF models.

   Service Creation Velocity

Accelerate service creation velocity with rapid solution rollout and extensibility. Prepackaged use case templates help speed time to market. The extensible Cisco Policy Suite for Mobile lets operators go beyond standard policy definition to support nonstandard, proprietary interfaces and customized service logic without affecting the core platform.
