Dedicated policy equipment standardized in 3GPP that enables the policy function for bandwidth and charging on multimedia networks.

PCRF is a fairly new term, introduced in September 2007 when standards for the 3GPP Policy Charging Control (PCC) architecture were published. The PCRF function is part of the larger PCC architecture, which also includes the Proxy Call Session Control Function (P-CSCF) and the Policy and Charging Enforcement Function (PCEF).

Combined, the elements of the PCC provide access, resource, and quality-of-service (QoS) control.

PCRF is an important part of IMS architectures, although it is not exclusive to the 3GPP-based network in which it was certified. It works across wireless networks and can come pre-integrated in a standard IT server.

PCRF is often referred to as policy server or -- formerly -- a Policy Decision Function (PDF).

PCRF is an important element in Service Provider Information Technology (SPIT). The PCRF interfaces with the main packet gateway and takes charging enforcement decisions on its behalf. The centralized device can act as a policy decision point (PDP) for the wireless operator and gets as granular as individual subscribers.

For example, service providers can use PCRF to charge subscribers based on their volume of usage of high-bandwidth applications, charge extra for QoS guarantees, limit app usage while a user is roaming, or lower the bandwidth of wireless subscribers using heavy-bandwidth apps during peak usage times. (See The SPIT Manifesto.)

Companies that offer PCRF functionality include the major equipment vendors -- Alcatel-Lucent (NYSE: ALU), Ericsson AB (Nasdaq: ERIC), HP Inc. (NYSE: HPQ), Juniper Networks Inc. (NYSE: JNPR), and Nokia Networks -- and specialists, including Bridgewater Systems Corp. (Toronto: BWC), BroadHop Inc. , Camiant Inc. (now part of Tekelec ), Openet Telecom Ltd. , Telcordia Technologies Inc. , and Volubill .

PCRF Is revolving now
With full compliance to 3GPP standards and extensive proven IOT success, Alepo's PCRF can be readily introduced into any multi-vendor evolved packet core (EPC) network environment. Its flexible, open architecture reassures service providers of a high-performance, reliable, and endlessly scalable solution that continues to deliver even as the network grows and evolves. Alepo's PCRF can also be deployed alongside Alepo's Online Charging System to create a robust, tightly coupled Policy & Charging Control platform that unleashes even greater possibilities in how service providers approach IP data monetization and control.

Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.

During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.

She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
