Volubill Business System (VBS) is a policy and charging control system designed to manage user experience and interactivity with access and data services in real-time. It supports services provided over mobile, fixed or partner broadband services and targeted at network operators, MVNOs and IP service providers.

It enables operators to become more profitable by capturing a greater addressable market with segmented plans, whilst controlling underlying network resources, service access and resource selection to minimise capacity costs, ease congestion and deliver against subscriber SLA. It looks after the customer experience with quality of service management, timely dialogues and device sensitive self-care for personalisation, status and advice of service.

These capabilities are delivered in a format that allows operators swift and self-reliant service change through a flexible and intuitive ‘click to deliver’ interface. VBS is designed to interoperate with legacy IT infrastructure that holds subscriber and service information in disparate architectures to maximise investments in existing systems and processes. Finally VBS provides standard 3GPP and IETF compliant interfaces alongside full support of vendor proprietary interfaces to interoperate, control and orchestrate across network gateways, service platforms and partner services.

Business Capabilities : Service segmentation, personalisation and tiered charging Subscriber volume, time, application, location and event usage management Top-up, bolt-on and on-demand service access provisioning and charging Overage and fallback package management VoIP, messaging and video service management Service differentiation using flexible policy rules (for example; facebook.com package extension, roaming packages, time-zone dependent quality of service, loyalty based prioritisation and location dependent usage metering) Multi-SIM and tethered device management Multi-user, shared services and account hierarchy management Bill shock management Pre-paid revenue assurance Single service across multi-networks orchestration Traffic offload sensitive packages Telco 2.0 open network business models Partner interactivity and settlement Parental control Aligned for 4G LTE/EPC, FTTH and FMC network migration Comprehensive support for multi-subsidiary and hosted partner organisations

Functional Capabilities : Comprehensive and intuitive subscriber service, package and network policy modelling Full 3GPP PCC compliance including PCRF, OCS/OFCS and SPR In-built or cached mediation with external IN/Balance system IETF and 3GPP Gx, Gy, Rx, S9, Sy and Sp standard and vendor proprietary interfaces Device sensitive captive self-care portal Customer notifications, messaging and dialogue Service redirection and re-routing control Provisionable subscriber data repository with optional customer care interface Real-time dynamic rating and charging including VoIP destination, taxation and discount management Multi-tenant hub deployment capabilities with full logical separation, cloud-hosting and localisation controls Partner account management, revenue sharing and settlement Open northbound integration with external subscriber and service data systems Voucher management including top-up and VoIP calling cards Traffic offload control including IFOM and SIPTO compliance In-built active or passive Authentication, Authorisation and Accounting (AAA) Integrated network and service signalling distribution, load-balancing and routing Subscriber service reporting, statistics and UDR generation Account receivables and general ledger support In-built network and service transaction signalling distribution, load-balancing and routing Comprehensive system monitoring and high availability management

The Policy and Charing Control functionality within VBS can be deployed in a modular format, to suit existing eco-system investments and later seamless extension. Specifically as:

• VBS Policy Manager - an enhanced 3GPP PCRF product with open SPR
• VBS Convergent Charging - an enhance 3GPP  OCS/OFCS product  with open SPR
