Ancillary Reports

Business Issue:  Engineering tools, which inquire as to the subscriber's minutes of usage of ancillary services such as N11, 8XX, and Operator Assistance throughout all markets. Some carriers currently outsourcer's third party service providers to supply Directory Assistance Call Completion (DACC), 8XX Outbound, as well as Operator Assisted calls. Service Level Agreements (SLA) are negotiated with service providers base upon monthly estimated call volume. Additionally, commissions are paid to carriers by service providers for call volume presented to their organization for terminations. The commission rates are based upon predetermined estimated monthly call volume. Inaccurate estimates may result in penalty fees paid by carriers for not meeting a minimum required volume of calls. Accurate subscriber usage of these ancillary services also establishes the basis of proper trunk sizing. 

CDR Applicability: These Call-Detail records can be analyzed to determine usage and patterns of subscriber ancillary services. Proactive monitoring of subscriber usage of ancillary services maximizes commissions paid to carriers and saves money by properly sizing trunk capacity.

Query Applications

• A link to the carriers website enables potential customers to compare their own TN against the carriers Local Service Area for Portability- saving them from the disappointment of attempting to Port their Number to an area not served

• A link to the carriers website enables customers to query their own minutes used against their plan

Traffic Analysis: The CDR's can be segregated by time domain and analyzed to provide the call arrival rate, average holding time, traffic intensity (Erlangs), traffic intensity during busy hour and the spectral efficiency.  From the spectral analysis, the nonlinear relationship between the system bandwidth and the amount of traffic carried by the system can be measured.  From the average traffic per user (Erlangs/user) during the busy hour and Erlangs per km² per MHz, the capacity of the system in terms of users per km² per MHz can be obtained. From the traffic intensity, the blocking probability is calculated which directly affects the spectral efficiency.  The spectral efficiency is calculated in Erlangs/MHz / km² 

The chart below represents an example of Erlangs plotted as a function of the top ten cell sites during the day and the busy hour.
