System and method for analyzing wireless communication data

A system for processing call detail records, the system comprising:

• means for receiving multiple call detail records, the call detail records related to wireless telecommunication service usage by a wireless telecommunication subscriber during multiple billing periods;
• means for producing a single calling profile record from the multiple call detail records, the calling profile record representing a profile of the wireless telecommunication service usage by the wireless telecommunication subscriber, wherein the means for producing is further configured to produce a calling profile record for each of a plurality of billing periods;
• means for determining a trend of the calling profile records over the plurality of billing periods;
• means for calculating an expected usage profile based on the determined trend and for calculating an estimated cost for each of a plurality of rate plans, at least one of the rate plans being the rate plan currently in service by the wireless telecommunication subscriber, each estimated cost being calculated on the basis of the expected usage profile;
• and
• means for processing each estimated cost to determine one or more of the most cost-effective rate plans;
• wherein the means for determining the trend further comprises means for weighting each calling profile record in a manner such that calling profile records of more recent billing periods are weighted more heavily.

A computer program stored on a computer readable medium, the computer program comprising:

• logic configured to receive multiple call detail records related to telecommunication service usage by a telecommunication user during a predetermined period;
• logic configured to produce a calling profile record from the multiple call detail records, the calling profile record representing a profile of the telecommunication service usage by the telecommunication user during the predetermined period, wherein producing the calling profile record further comprises producing a calling profile record for each of a plurality of billing periods;
• logic configured to determine a trend of the calling profile records over the plurality of billing periods;
• logic configured to calculate an expected usage profile based on the determined trend;
• logic configured to factor the expected usage profile in order to calculate an estimated cost for each of a plurality of rate plans;
• and
• logic configured to process each estimated cost to determine one or more of the most cost-effective rate plans;
• wherein determining the trend comprises weighting each calling profile record in a manner such that calling profile records of more recent billing periods are weighted more heavily.
