Abstract
Abstract A new destination number determination switching system is provided for a telecommunications environment in which a called party has discontinued an old called party destination number and obtained a new called party destination number. The new destination number determination switching system is used to obtain the new called party destination number when a calling party places a call to the old called party destination number. The switching system includes a hub switch that receives a rerouted call from a corresponding original destination switch. The hub switch corresponds to a routing number prefix used to reroute calls from the corresponding original destination switch to the hub switch. The routing number prefix causes the hub switch to initiate a trigger to a network platform that obtains the new called party destination number.

Claim 2
Dependent Claim
103 words
A new destination number determination switching system for a telecommunications environment in which a called party has discontinued an old called party destination number and obtained a new called party destination number, the switching system comprising: a hub switch that receives at least one call, to the old called party destination number, rerouted from at least one original destination switch associated with the old called party destination number, based on a routing number prefix associated with the hub switch, the routing number prefix causing the hub switch to initiate a trigger to a network platform that obtains the new called party destination number.
Claim 3
Dependent Claim
34 words
The new destination number determination switching system of claim 1 , the hub switch further receiving a determination from the network platform indicating whether the called party has authorized payment for forwarding the call.
Claim 4
Dependent Claim
43 words
The new destination number determination switching system of claim 2 , the hub switch further forwarding the call to the new called party destination number when the hub switch receives a determination that the called party has authorized payment for forwarding the call.
Claim 5
Dependent Claim
52 words
The new destination number determination switching system of claim 1 , the hub switch further forwarding the routing number prefix and a code identifying the at least one original destination switch to the network platform to be used to determine a number plan area (NPA) of the old called party destination number.
Claim 6
Dependent Claim
38 words
The new destination number determination switching system of claim 1 , wherein the routing number prefix is determined based on a number plan area (NPA) corresponding to an area served by the at least one original destination switch.
Claim 7
Dependent Claim
57 words
The new destination number determination switching system of claim 1 , further comprising a database that stores the old called party destination number in association with the new called party destination number, the network platform obtaining the new called party destination number from the database and forwarding the new called party destination number to the hub switch.
Claim 8
Dependent Claim
55 words
The new destination number determination switching system of claim 1 , the hub switch further receiving a determination from the network platform whether the called party has authorized forwarding the call, and forwarding the call to the called party using the new called party destination number when the called party has authorized forwarding the call.
Claim 9
Dependent Claim
129 words
A new destination number determination switching system for a telecommunications environment, in which a called party has discontinued an old called party destination number, the switching system comprising: a first switch that receives a call from a calling party to the old called party destination number and determines that the old called party number is discontinued, and that changes a routing number prefix of the old called party destination number to a predetermined rerouting number prefix; and a second switch that receives the call from the first switch, the second switch associated with the rerouting number prefix, the rerouting number prefix causing the second switch to initiate a trigger to a network platform that obtains a new called party destination number associated with the old called party destination number.
Claim 10
Dependent Claim
129 words
A new destination number determination switching system for a telecommunications environment, in which a called party has discontinued an old called party destination number, the switching system comprising: a first switch that receives a call from a calling party to the old called party destination number and determines that the old called party number is discontinued, and that changes a routing number prefix of the old called party destination number to a predetermined rerouting number prefix; and a second switch that receives the call from the first switch, the second switch associated with the rerouting number prefix, the rerouting number prefix causing the second switch to initiate a trigger to a network platform that obtains a new called party destination number associated with the old called party destination number.
Claim 11
Dependent Claim
34 words
The new destination number determination switching system of claim 8 , the second switch further receiving from the network platform a determination indicating whether the called party has authorized payment for forwarding the call.
Claim 12
Dependent Claim
47 words
The new destination number determination switching system of claim 9 , the second switch further forwarding the call to the called party using the new called party destination number when the second switch receives a determination that the called party has authorized payment for forwarding the call.
Claim 13
Dependent Claim
48 words
The new destination number determination switching system of claim 8 , the second switch further forwarding the rerouting number prefix and a code identifying the first switch to the network platform to be used to determine a number plan area (NPA) of the old called party destination number.
