Patent ID: 8442512

Claim:
A method of operating a call duration analysis system, the method comprising: receiving a plurality of call detail records (CDRs) from a network database, wherein the CDRs comprise information associated with a plurality of calls over a wireless communication network; processing the CDRs to determine an average call duration for the wireless communication network; processing the CDRs with the average call duration for the wireless communication network to determine at least one wireless access node associated with a below-average call duration, wherein the below-average call duration is determined by comparing an average call duration for the wireless access node with the average call duration for the wireless communication network; processing the CDRs associated with the wireless access node to determine a first set of the CDRs associated with the wireless access node exhibiting a good radio frequency (RF) status and a second set of the CDRs associated with the wireless access node exhibiting a bad RF status; and processing the first set of the CDRs to determine a wireless communication device type associated with the below-average call duration.
