The Aptilo Policy Manager goes beyond the scope of a standard PCRF (Policy Charging and Rules Function) with the addition of a built-in repository for subscriber data and policy definitions as well as policy-based IP configuration and routing control. The system is designed to be flexible to allow 3 Scandinavia to add unique, dynamic service configurations that can be constantly modified according to the needs of their customers, with minimal cost and effort.
“Aptilo demonstrated a thorough understanding of our needs within the policy and IP management domains. Their innovative approach and flexibility will allow us to keep on delivering a multitude of data services effectively to our customers” said Jörgen Askeroth, CTO, 3 Scandinavia. “Aptilo’s track record of overall responsibility also ensures quality operations of the delivered solution.”
The Aptilo Policy Manager is built on the new Aptilo Service Management Platform™ ALE architecture in which functionality is divided into three distinct layers: a management layer for configuration and monitoring, a control layer for protocol-level interactions with external systems and an execution layer for application logic processing.
The different layers can be distributed over several industry-standard hardware server nodes to increase capacity where it is needed most and obtain high availability including geographic redundancy and distribution.
The control layer runs a number of protocol adapters that facilitate interoperability with the required set of external systems. These protocol adapters include RADIUS, Diameter, BGP (Border Gateway Protocol), SOAP/XML and SNMP. New adapters are introduced as needed to implement new or modified relationships with external systems.
The policy decisions made in the execution layer - according to rule sets designed and configured by the operator - are based on a combination of data received from a configurable set of external provisioning systems, real-time data received from the production network and the accumulated status of ongoing sessions. It then triggers actions toward external systems such as packet core gateways and DPI (Deep Packet Inspection) nodes to enforce the policy decisions.
The highly flexible architecture, both in terms of adding new interfaces and protocols as well as new business logic by the means of a simple configuration, makes the Aptilo Policy Manager ideal for mobile broadband operations where rapid time-to-market of new services is critical.
The Aptilo Policy Manager allows the operator to exercise detailed control over the flow of traffic as well as the amount of resources that are allocated to and consumed by end-users.
“We did not want to come to market as just another PCRF. That is why we added subscriber management, highly flexible protocol adaptors, policy-based IP configuration and routing control to our Policy Manager. We call this advanced functionality PCRF+,” said Torbjörn Ward, CEO, Aptilo Networks. “Furthermore, as our Policy Manager is built on the Aptilo Service Management platform, it can easily be expanded with additional functions such as portal management and charging.”
