Service-Aware Policy Controller

Ericsson's Service-Aware Policy Controller (SAPC) allows increasing revenue through personalized services while optimizing the utilization of network resources 

The Ericsson Service-Aware Policy Controller (SAPC) product is conceived based on 3GPP Policy and Charging Rules Function (PCRF) and PCF (Policy Control Function). SAPC is responsible for the policy control and charging rules that define the services and applications supported in mobile (2G, 3G, 4G, 5G NSA, 5G SA), fixed and converged telecom networks. SAPC is key to secure the network behavior when users access data services, such as, authorizing the services, assigning the QoS of the data-session and the Charging that shall be applied; and performs a business critical role for monetization and differentiation of operator’s mobile and converged broadband commercial packages.
The Ericsson SAPC product is an important component of Ericsson’s solutions for Broadband Networks as Evolved Packet Core (EPC), Mobile Telephony Evolution with VoLTE and Wi-Fi Calling, and BSS to name some. SAPC is also a central piece of Ericsson Dual-mode 5G Cloud Core solution.
Being compliant with 3GPP standards, the SAPC is fully inter-operable with other network elements, including Packet Gateways (PGW, GGSN), stand-alone packet inspection nodes (DPI), Session Management Function (SMF), Access & Mobility Management Function (AMF), Application Function (AF), User Data Repositories (UDR) and Charging Systems (CS) units.
In addition to the standard capabilities, Ericsson SAPC includes a number of added-value features to increase network efficiency and shortens TTM.
With the SAPC you support, for example, the following use cases:

• Set policies on a per-user or per-user-group basis
• Control access to premium content
• Control access based on accumulated usage
• Use quality of service control to ensure an enhanced user experience for
services requiring a high or varying bandwidth
• Optimize utilization of network resources by applying quality-of-service
• Select the radio access technology for a subscriber to attach to
• Select a core network instance

Ericsson SAPC also supports the revenue generation:

• Personalizing services – making services more user-friendly to increase
usage and builds loyalty
• Maintaining fair-usage policies – preventing users of file-sharing services
from violating terms and conditions of their subscription
• Differentiating service offerings – introducing different tiers of
subscriptions with different characteristics depending on, for example, network load or time of day.
The Policy Controller is included in SAPC (Service Aware Policy Controller) and CCPC (Cloud Core Policy Controller) Ericsson products. SAPC is the virtualized version while CCPC is the containerized version, including both PCRF (Policy and Charging Rules Function, for 2G/3G/4G) and PCF (Policy Control Function for 5G). Both of them are based on the leading Ericsson SAPC product. SAPC product includes EPC-NSSF (early slice selection based on GW selection), A-PCRF (radio-frequency selection), PCRF (session management policies). CCPC includes AM-PCF for access and mobility control and SM-PCF for session-management control.

Personalized service offering

SAPC provides the ability to authorize and offer personalized services increasing service usage and making stronger customer relationship as a result of a better usability.

The use of Ericsson Service-Aware Policy Controller policies allows operators to easily launch creative and personalized offers, based on a wide set of parameter including the user profile, time of day, location, service type, QoS profile, charging characteristics, etc.

Outstanding flexibility and usability

SAPC’s policy engine is the most flexible engine in the market allowing a high level of programmability and a high number of different rules. The use of policies per subscriber or subscriber group allows operators to easily customize their service access rules to match ever-changing market requirements.

SAPC is the leader in Policy Management Efficient and flexible operations

Ericsson's policy management market leadership has been recognized by leading industry analyst Current Analysis in their most recent evaluation of the Policy Management market.

As their report says: “The Ericsson Service-Aware Policy Controller (SAPC) is a leader among compared policy control solutions. Ericsson’s SAPC includes extensive wireless access network and backhaul integration in addition to the company’s own online charging system (OCS)/offline charging system (OFCS), policy control enforcement function (PCEF)/deep packet inspection (DPI) and subscriber data management (SDM) products. These capabilities provide the SAPC with an unparalleled IP network reach supported with strong 3GPP interface compliance and wide, although unnamed, third-party interoperability credentials. Ericsson continues to optimize its policy assets to provide high availability and carrier-grade end-to-end support for VoLTE services and NFV/cloud adoption. Over 200 customer engagements validate Ericsson’s technology, providing the company with deep experience and ongoing exposure to the evolving requirements of the policy control market.”

Centralized policy management functions help reduceCAPEX and OPEX. With the SAPC you are able to set policies on a per-user or per-user-group basis, giving them the flexibility to customize service access rules to match changing market requirements.

The SAPC is designed to work as a Policy and Charging Rules Function (PCRF) in IMS networks and in the Evolved Packet Core (EPC) network architecture according to SAE.
