“Losses due to revenue leakages amount to 3 to 8% of total revenues, and sometimes reach as high as 15%” *

Impact of New ServicesThe Pipe is Getting Longer & M ore Complex
Service providers are looking to sell content, commerce and communications as an augmented product
• Irrespective of wireless/wireline market –more services are becoming available
• New technologies like IP and 2.5G/3G convergence are powering this
• 3rd party content like ringtones and games -Now you need to worry about Billing On Behalf of Others (BOBO)
• Each new service introduces a new type of leak, and a new type of misuse, a new type of ‘leaky pipe’

React slowly = lost revenueThe time between a RA issue arising and deploying a revenue assurance solution to locate/solve is lost revenue:
• You have to realize that there could be a hole
• W ait for a solution to be developed
• And patch it
But what if the hole is significant, but hard to see?
• Classic business decision making problem: too much data, not enough information
• Drowning in a sea of data –not able to find the RA issues
• Bridging the irrelevance gap –drilling down to the nuggets

Detection of Simplistic CLEC Arbitrage
Sprint’s local network noticed that terminating volumes were rapidly increasing from a select group of Competitive Local Exchange Carriers (CLECS)
Agilent’s’acceSS7 system was able to see multi-jurisdictional traffic on a local interconnection trunk group.
Interconnection contract restricted the traffic to be terminatedon these trunks to local and non-equal access intralata traffic.
— Test calls verified the Agilent data— Sprint has investigated four CLECs and have found
similar patterns of arbitrage. These companies were billed in excess of $7 Million US in lost access revenues.
— Sprint is currently investigating other CLECs.

Auditing for AM A
Perform AM A audits utilizing SS7 data for Switched Access revenue
• Randomly select “newly” installed trunk groups to validate AM A recording.
• In event of no AM A, are able to take SS7 data and back bill carriers.
• Revenue recovery for future opportunity and back billing are significant considering the small base of trunk groups included in this analysis..
Analysis M ethod (comparing Old to New)
• Old M ethod ---Very manual process utilizing switch trunk usage data.
• New M ethod ---Agilent BI tool allows means to automate extraction of new trunk groups and summarize trunk groups that are billable, then compare it to switch AM A files.

Customer Caller ID Complaints
Investigating Complex Call Scenarios
• POTS North Carolina customer complained that their number was appearing on caller ID all over the country and they weren’t making these calls. Customer was ready to cancel service with Sprint!
• SS7 correlated call records provided discovery information to aid in identifying the cause leading to a quick resolution
Analysis M ethod (comparing Old to New)
• Old M ethod ---Switch engineers could not locate source of problem through traditional translations tools. No exposure to why and where this number was populating inappropriately.
• New M ethod ---Extracted SS7 correlated call records from Agilent BI. Identified problem was not end user switch, but rather a competitor’s switch as indicated by JIP and point code information.

One W ay Traffic Trunk Groups
Trunk groups that should only be carrying one-way traffic are allowing 2-way bi-directional and no AM A creation
• SS7 summary records targeted to report trunk groups that should only have one-way traffic.
• Significant revenue opportunity determined for the limited number of trunk groups identified.
Analysis M ethod (comparing Old to New)
• Old M ethod ---Limited exposure to summarized data utilizing traditional switch trunk usage reports.
• New M ethod ---Agilent reports provide summary data at a trunk group level with traffic direction indicators.

Validating Reciprocal Compensation Expenses
Lack AM A recordings to validate reciprocal compensation expense
• Summary Trunk group reports aid the Finance Access Verification organization in reviewing and comparing billing expense from CLEC’s.
Analysis M ethod (comparing Old to New)
• Old M ethod ---No data available to validate expense
• New M ethod ---Agilent reports provide listing of M OU’s by carrier
