Bridgewater Systems - Service Controller in CDMA Networks

Deployed in networks serving thousands to tens of millions of subscribers, the Bridgewater® Service Controller offers unparalleled scalability, reliability, and extensibility for CDMA service providers. The Service Controller is the leading network access control solution, serving 85% of the North American CDMA market, including market-leading service providers such as Verizon Wireless, Sprint Nextel, and Bell Mobility.

Improved subscriber adoption of mobile data services can drive significant increases in ARPU for service providers. The Service Controller helps CDMA service providers capitalize on this opportunity by:

Providing scalability and performance to meet the needs of complex network applications.
Processing large volumes of state-based accounting transactions, reducing the chance of revenue leakage.
Delivering multi-fold increases in successful subscriber sessions, thereby improving subscriber satisfaction with their network experience

FEATURES AND BENEFITS

Seamless subscriber experience.
Full support for the wireless Mobile IP (MIP) standards required for mobile network roaming.
Enables QoS-based service tiers and QoS management for specific flow definitions within CDMA EV-DO Rev A.
Simultaneous support of multiple EAP methods, including EAP-TLS, EAP-TTLS, EAP-SIM and EAP-AKA, to ensure a seamless subscriber experience.
Customer self-care – enables online self-service portals that allow subscribers to see and alter their service packages and choices, which is proven to reduce customer care calls by 40%.

Centralized management

Centralized subscriber management enabled by Bridgewater’s Subscriber Data Broker™ provides the foundation for differentiated services, hierarchical subscriber and service administration, and granular, profile-based control of subscriber entitlements.
Push-and-pull policy decision point (PDP) allows subscriber entitlements to be managed and enforced through profile-associated attributes and credentials that may be presented on demand to the application infrastructure.
Lawful intercept support identifies when surveillance targets are on-net for Communications Assistance for Law Enforcement Act (CALEA) compliance.

Revenue opportunities and management

Provides profiles and policies to define QoS-based service tiers while enforcing fair usage.
Supports standards-based RADIUS prepaid for duration- or volume-based prepaid packet-data services.
Support for multiple business models (wholesale, retail, etc.) allows CDMA service providers to leverage new businesses such as mobile virtual network operators (MVNO).
Subscriber redirection helps prevent revenue leakage and manage subscriber usage.
Extensive profiling and user self administration makes customized and personalized access quick and easy, enabling service bundling to a broad range of subscriber segments that receive services based on evolving preferences.

Enhanced security

Dynamic Mobile IP Key Update (DMU) allows authentication and key distribution via RSA public-key cryptography to allow scalable, mutual authentication.
Mobile Identification Number Check (MINCheck) fraud-control mechanism safeguards against identity hijacking.
Return attribute filtering provides safeguards to protect the privacy of subscriber information.
System access security via SSL or ARC4 encryption over HTTPS with X.509 certificate.

Future-proof solution

Simultaneous multi-protocol (RADIUS/Diameter) support protects investments in legacy applications and enables migration to next-generation networks.
Vendor and network agnosticism enables easy integration in mixed vendor deployments and converged networks
Proven to scale to support increasing numbers of subscriber and transaction rates.

Flexible architecture and superior performance

Simultaneous support of multiple access technologies on a single server platform; highly scalable, high-performance RADIUS and Diameter engines with proven interoperability; improved network uptime and subscriber satisfaction with multi-network convergence.
Deployment architecture includes numerous options for high availability, database replication, system redundancy, and application decoupling.
Intelligent RADIUS proxy minimizes the operational impact of non-performing proxy targets.
Extensive and proven interoperability accelerates time to market and prevents expensive custom integration.
Dynamic home agent support ensures that calls are routed via the optimal home agent, depending on usage, system health, and the subscriber’s location.
