Trunk design optimization for public switched telephone network
First Claim
1. A method for identifying misrouted traffic in a telecommunications network, the method comprising:
- identifying a first switch and a second switch in the telecommunications network, the first switch and the second switch being directly connected by a trunk;
determining whether traffic from the first switch to the second switch passes through a third switch during a select time period;
determining whether the direct trunk experiences overflow during the select time period; and
when traffic from the first switch to the second switch is determined to have passed through the third switch during the select time period, and when the direct trunk is determined not to have experienced overflow during the select time period, designating the traffic that passed through the third switch as misrouted traffic.

Abstract
A method and system enable optimization of trunk group design in a public switched telephone network (PSTN). A community of interest, including two end offices connected by a direct trunk and at least one tandem switch, is identified using out-of band signaling data collected from the PSTN. An application server interfaced to the PSTN determines whether traffic in the community of interest passes through the tandem switch during a predetermined time period. When traffic passes through the tandem switch, the application server further determines whether the direct trunk between the end offices experienced an overflow condition during the same predetermined time period. When the direct trunk did not experience an overflow condition, an exchange code associated with the traffic passing through the tandem switch is designated as a misrouted code. The misrouted code is flagged so that associated traffic is redirected through the direct trunk.

8. A computer readable medium for storing a computer program that identifies misrouted traffic in a telecommunications network for use in optimizing design of the network, the telecommunications network comprising at least a first switch and a second switch directly connected by a trunk, the computer readable medium comprising:
-
a first determining code segment that determines whether traffic from the first switch to the second switch passed through a third switch during a select time period;
a second determining code segment that determines whether the direct trunk experienced overflow during the select time period; and
a designating code segment that, when traffic from the first switch to the second switch is determined to have passed through the third switch during the select time period, and when the direct trunk is determined not to have experienced overflow during the select time period, designates traffic that passed through the third switch as misrouted traffic. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method for enhancing design of a telecommunications network by identifying traffic flow through a community of interest of the telecommunications network, the community of interest comprising at least a first switch and a second switch, the method comprising:
-
collecting signaling data from the telecommunications network regarding the traffic flow through the community of interest;
determining whether an offered load of traffic through the community of interest exceeds a predetermined amount during a predetermined time period, based on the signaling data;
when the offered load exceeds the predetermined amount, determining whether a direct trunk connects the first switch and the second switch in the community of interest; and
when a direct trunk does not connect the first switch and the second switch, identifying a path between the first switch and the second switch as a new high usage direct trunk opportunity. - View Dependent Claims (15, 16, 17, 18)

19. A computer readable medium for storing a computer program that identifies traffic flow through a community of interest in a telecommunications network, for use in optimizing design of the network, the community of interest comprising at least a first switch and a second switch, the computer readable medium comprising:
-
a data collecting code segment that receives signaling data from the telecommunications network regarding the traffic flow through the community of interest;
a determining code segment that determines whether an offered load of traffic through the community of interest exceeds a predetermined amount during a predetermined time period, based on the signaling data, and when the offered load exceeds the predetermined amount, determines whether a direct trunk connects the first switch and the second switch in the community of interest; and
an identifying code segment that, when a direct trunk does not connect the first switch and the second switch, identifies a path between the first switch and the second switch as a new high usage direct trunk opportunity. - View Dependent Claims (20, 21, 22, 23)
