JSM (Jet Subscriber Manager), a Policy and Charging Rules Function (PCRF) software, is the core element of a comprehensive Policy and Charging Control (PCC) solution. This module is a software suite designed to integrate DPI with operator systems, execute sophisticated scenarios, notify and charge subscribers. In particular, JSM is capable of traffic categorization and management:

  • in accordance with subscriber profiles and tariff plans;
  • by connection (RAT-Type);
  • in accordance with the client's online accounting/charging status between sessions and within a session (e.g. depending on the turbo button status);
  • in accordance with the status of the network segment (base station congestion management).

JSM’s component architecture can be easily scaled up and/or customized to fit the needs and systems of a particular operator (in terms of billing, personal profiles, authorization rules and so on).

JSM has a capacity of over 15,000 TPS and can support more than a million active connections in fault-tolerant Active\Active and Active\passive configurations.

Support of protocols and interfaces

JSM supports the following protocols and interfaces:


  • Policy and charging control over Gx (3GPP TS 29.212 Release 10)
  • Policy and charging control over Rx (3GPP TS 29.214 Release 10)
  • Diameter Credit-Control Application (RFC 4006)
  • Online charging over Gy (3GPP TS 32.299 Release 10)

RADIUS Channel

  • RADIUS Accounting (RFC 2866)

HTTP Channel


DPI Channel


Simple Network Management Protocol (SNMP)

  • SNMPv3

Why an operator needs JSM

Today's operators are facing heavy competition, increasing subscriber activity and proliferation of new web services. They have to deal with three fundamental business challenges.

(1) Revenue generation. This includes an increase in ARPU, reduction of unit bandwidth cost for flat-rate plans and securing revenue from alternative markets such as OTT or Internet advertizing.

(2) Cost reduction. This goal covers reduction of data transfer costs and prevention of traffic loss due to network congestion either by prioritizing traffic or relieving the overloaded segment.

(3) Last, but not least, is the issue of customer loyalty and churn control. This requires better communication with customers to send valuable information and receive feedback.

A mobile carrier with over 500,000 subscribers awarded Jet Infosystems a contract to develop an active traffic management system based on customer profiles, tariff plans, account status and network congestion. Once installed, the system improved network performance by 15%.

Such large-scale projects require an integrated array of components that need to fit the operator’s existing systems. While offering an excellent in-house suite for dynamic traffic management, Jet Infosystems can also deploy it on a turnkey basis using its ample experience in the installation of products from different vendors.
