Product Line(s)

Mobile network operators are now looking to data for revenue. The ability to track the use and type of data services is essential to operator profitability. When a device that tracks this information fails, call detail records (CDRs)-and their associated revenues-can be lost. Outages can be planned (system upgrades) or unplanned (network connection failure or data collector failure). A redundant data collector setup is not enough-reliable physical media is necessary to safely store the CDRs generated during an outage.
The Cisco PSD is a service module for Cisco Catalyst 6500 Series and Cisco 7600 Series switches. It functions as an extension to the existing storage on the Cisco Content Services Gateway (CSG) or Cisco Gateway GPRS Support Node (GGSN). During an outage, the Cisco Persistent Storage Device (PSD) captures and stores the usage information until the billing mediation agents come back online, assuring service providers that their billing records are protected.
Under normal operating conditions, the Cisco CSG or Cisco GGSN sends the CDRs to the billing data collectors as long as the devices are reachable. If the billing data collectors become unavailable, the Cisco CSG or Cisco GGSN redirects the CDRs (including those not acknowledged by the data collectors before they went down) to the Cisco PSD. With its 37 GB of onboard storage space, the Cisco PSD can safely store up to a week of CDRs from as many as three Cisco CSGs or three GGSNs.
The Cisco CSG or Cisco GGSN continues to check the availability of the billing data collectors. As soon as they are again ready to receive CDRs, the Cisco CSG or Cisco GGSN automatically retrieves the CDRs stored on the Cisco PSD and delivers them to the billing data collectors. The whole process requires no operator intervention, and the operator can be confident that no billing information will be lost.
