1. A method for analyzing the effects of network events on call services comprising:
- receiving a plurality of call detail records (CDRs) from a plurality of network devices, each of the plurality of CDRs including a time stamp, call service data and call destination data;
grouping the plurality of CDRs into a plurality of first subgroups according to corresponding network devices and to the time stamps of the plurality of CDRs;
for each of the plurality of first subgroups, grouping the CDRs into a plurality of second subgroups according to a call service data and call destination data; and
generating call statistics indicative of a state of call services from data contained in the CDRs for each of the plurality of second subgroups.

Abstract
A system and method for managing a telecommunications network through near real time analysis of Call Detail Records (CDRs) is provided. The system and method of the invention reports how a particular call service is performing and how its performance deteriorates as a result of any type of network event, including both hardware and software related events. A feature of the invention is that it provides several levels of service impact reporting, thus providing users with more versatile and detailed network management capabilities.

5. A method for analyzing the effects of network events on call services comprising:
-
receiving a plurality of call detail records (CDRs) from a plurality of network devices, each of the plurality of CDRs including a time stamp, call service data and call destination data; grouping the plurality of CDRs into a plurality of first subgroups according to corresponding network devices and to the time stamps of the plurality of CDRs; for each of the plurality of first subgroups, grouping the CDRs into a plurality of second subgroups according to a call service data and call destination data; generating call statistics indicative of a state of call services from data contained in the CDRs for each of the plurality of second subgroups; generating a threshold value for each call statistic, each threshold value including a dynamic mean value of a corresponding call statistic over a selected time period; comparing each call statistic to a corresponding threshold value and visually coding the statistics responsive to the comparison; and displaying the visually coded statistics to indicate call service alarm conditions.
