Abstract
Abstract A telecommunication network includes a number of switches interconnected by groups of trunk circuits. Trunk traffic data is generated by the switches and transmitted to a network control center where it is stored in a traffic database. The network control center includes a system for mechanically generating periodic traffic reports and performing calculations leading to recommendations pertaining to additions or deletions of the number of trunks in a group necessary to maintain an optimum size network.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
144 words
In a telecommunication network having a plurality of tandem node switches interconnected by a plurality of trunk groups, a system for mechanically generating traffic data reports and recommending additions or deletions of trunks in an unqueued trunk group necessary to maintain an optimum size network, said system comprising: means for reading and storing unqueued trunk group measurement packages provided by each tandem node switch; means for selecting as data days those days for which the average usage of a selected set of unqueued trunk groups exceeds a specified threshold; means for determining the average busy hour; means for determining the average offered load; means for calculating the amount of busy hour average blocking; and means for calculating the number of unqueued trunks to be added or deleted so that the calculated busy hour blocking is approximately equal to a target busy hour average blocking.
Claim 2
Dependent Claim

In a telecommunication network having a plurality of tandem node switches interconnected by a plurality of trunk groups, a system for mechanically generating traffic data reports and recommending additions or deletions of trunks in an unqueued trunk group necessary to maintain an optimum size network, said system comprising: means for reading and storing unqueued trunk group measurement packages provided by each tandem node switch; means for selecting as data days those days for which the average usage of a selected set of unqueued trunk groups exceeds a specified threshold; means for determining the average busy hour; means for determining the average offered load; means for calculating the amount of busy hour average blocking; and means for calculating the number of unqueued trunks to be added or deleted so that the calculated busy hour blocking is approximately equal to a target busy hour average blocking.
Claim 3
Dependent Claim
138 words
In a telecommunication network having a plurality of tandem node switches interconnected by a plurality of trunk groups, a system for mechanically generating traffic data reports and recommending additions or deletions of trunks in a queued trunk group necessary to maintain an optimum size network, said system comprising: means for reading and storing queued trunk group measurement packages provided by each tandem node switch; means for selecting as data days those days for which the average usage of a selected set of queued trunk groups exceeds a specified threshold; means for determining the average busy hour; means for determining the average offered load; means for calculating the average holding time; and means for calculating the number of trunks to be added or deleted so that the calculated queue delay is approximately equal to a target average queue delay.
Claim 4
Dependent Claim
138 words
In a telecommunication network having a plurality of tandem node switches interconnected by a plurality of trunk groups, a system for mechanically generating traffic data reports and recommending additions or deletions of trunks in a queued trunk group necessary to maintain an optimum size network, said system comprising: means for reading and storing queued trunk group measurement packages provided by each tandem node switch; means for selecting as data days those days for which the average usage of a selected set of queued trunk groups exceeds a specified threshold; means for determining the average busy hour; means for determining the average offered load; means for calculating the average holding time; and means for calculating the number of trunks to be added or deleted so that the calculated queue delay is approximately equal to a target average queue delay.
Claim 5
Dependent Claim
198 words
In a telecommunication network having a plurality of tandem node switches interconnected by a plurality of trunk groups, a system for mechanically generating traffic data reports and recommending additions or deletions of trunks in a queued or unqueued trunk group necessary to maintain an optimum size network, said system comprising: means for reading and storing trunk group measurement packages provided by each tandem node switch; means for selecting as data days those days for which the average usage of a selected set of trunk groups exceeds a specified threshold; means for determining the average busy hour; means for determining the average offered load; means for calculating the amount of busy hour average blocking of unqueued trunk groups; means for calculating the number of trunks to be added to or deleted from an unqueued trunk group so that the calculated busy hour blocking is approximately equal to a target busy hour average blocking; means for calculating the average holding time for a queued trunk group; and means for calculating the number of trunks to be added to or deleted from a queued trunk group so that the calculated queue delay is approximately equal to a target average queue delay.
Claim 6
Dependent Claim
198 words
In a telecommunication network having a plurality of tandem node switches interconnected by a plurality of trunk groups, a system for mechanically generating traffic data reports and recommending additions or deletions of trunks in a queued or unqueued trunk group necessary to maintain an optimum size network, said system comprising: means for reading and storing trunk group measurement packages provided by each tandem node switch; means for selecting as data days those days for which the average usage of a selected set of trunk groups exceeds a specified threshold; means for determining the average busy hour; means for determining the average offered load; means for calculating the amount of busy hour average blocking of unqueued trunk groups; means for calculating the number of trunks to be added to or deleted from an unqueued trunk group so that the calculated busy hour blocking is approximately equal to a target busy hour average blocking; means for calculating the average holding time for a queued trunk group; and means for calculating the number of trunks to be added to or deleted from a queued trunk group so that the calculated queue delay is approximately equal to a target average queue delay.
