Telephony transitioning system
First Claim
1. A method comprising:
- a) at a universal signaling point (USP), intercepting a call signaling message associated with a telephony element originally associated with a donor switching system from a call signaling network, the telephony element being at least one of the group consisting of telephony lines and telephony trunks; and
b) routing the call signaling message to;
i) the donor switching system if the telephony element is supported by the donor switching system, andii) a host switching system if the telephony element has been transitioned to the host switching system, the host switching system adapted to terminate call signaling messages, during the transition of the telephony element, for a first point code associated with the donor switching system and for a second point code associated with the host switching system.

Abstract
The present invention provides a Universal Signaling Point (USP) that acts as a liaison between a call signaling network and a number of switching entities, which support lines, trunks, or a combination thereof. During a transition of the lines or trunks from a donor entity to a host entity, call signaling between the host and donor entities and the SS7 network is routed through the USP. When transitioning the lines or trunks from the donor entity to the host entity, call signaling messages intended for the donor entity are routed to either the donor or host entity, whichever actually supports the lines or trunks. The USP is provided information indicative of whether a line or trunk has been transitioned to the host entity. The USP can compare information provided in the call signaling message with the transition information and route the message to the appropriate donor or host entity.

21. An apparatus comprising:
-
a) at least one interface facilitating links to a host switching system, a donor switching system, and a call signaling network; and b) a control system associated with the at least one interface and adapted to; i) receive a call signaling message associated with a telephony element originally associated with the donor switching system from the call signaling network, the telephony element being at least one of the group consisting of telephony lines and telephony trunks; and ii) route the call signaling message to; 1) the donor switching system if the telephony element is supported by the donor switching system, and 2) the host switching system if the telephony element has been transitioned to the host switching system, the host switching system adapted to terminate call signaling messages, during the transition of the telephony element, for a first point code associated with the donor switching system and for a second point code associated with the host switching system. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
