Method of and system for efficient use of telecommunication networks
DCFirst Claim
1. A method of use of a telecommunication network, comprising the steps of:
- (a) selecting a transmission path connecting a calling location and a called location, the step of selecting being carried out in a manner transparent to a calling party and a called party;
(b) receiving at a control location information from an intercept pertaining to a calling party identification number associated with the calling party and a called party identification number associated with the called party, the step of receiving being performed in a manner transparent to the calling party and the called party;
(c) determining whether a call from the calling location to the called party access number should be connected via the selected transmission path, the step of determining being carried out in a manner transparent to the calling party and the called party; and
(d) connecting the call from the calling party access number to the called party access number via the selected transmission path in a manner transparent to the calling party and the called party, when the step of determining results in a determination that the call should be connected via the selected transmission path.

Abstract
A system for use of a telecommunications voice network includes a communication node local to a calling location for acquiring calling and called party identification numbers and transmitting them to a central switching unit associated with a called location, through a transception channel independent of the telecommunications voice network. Further provided is a central switching unit for interrogating the called location to obtain a call supervision status thereof. Also provided is an apparatus for completing a first phonecall from the switching unit to the called location if the call supervision status is that of an answer, and for originating a second phonecall through the telecommunications network to the calling location. Teleconferencing of the first and second phonecalls then occurs. Further provided is an apparatus for providing an uncompleted call status signal to the central switching unit if the call status is that of a no answer or busy. The calling party is then appropriately advised. Upon termination of the second phonecall an answer supervision signal is sent by the local node to the central switching unit.

5. An apparatus for use in a communication network, comprising:
-
an intercept that selects a route passing through a control location for connecting a calling party telephone user equipment to a called party telephone user equipment, the intercept selecting the route in a manner transparent to the calling party telephone user equipment and the called party telephone user equipment; the intercept further being in communications contact with the control location in a manner that permits transmission of information from the intercept to the control location, the transmission being transparent to the calling telephone user equipment and the called telephone user equipment; the intercept evaluating information passed from the control location in a manner transparent to the calling telephone user equipment and the called party telephone user equipment to ascertain whether to connect a call via the selected route between the calling telephone user equipment and the called telephone user equipment and, if so, instructing that calls between the calling telephone user equipment and the called telephone user equipment be connected via the selected one route. - View Dependent Claims (6, 7)

8. A method for connecting a calling telephone user equipment and a called telephone user equipment comprising:
-
(a) establishing a connection between the calling telephone user equipment and a communication node local to a calling location; (b) acquiring a first identification number for the calling telephone user equipment and a second identification number for the called telephone user equipment at the communication node; (c) transmitting the first and second communication numbers from the communication node to a switching location; (d) placing a first phone call from the switching location to the called telephone user equipment; (e) substantially concurrently with step (d), placing a second phone call from the switching location to the communication node; (f) receiving at the switching location a status signal for the first phone call; and (g) terminating the second phone call before it is answered when the status signal indicates a status for the first phone call of no answer for a predetermined time or of busy.

9. A method of connecting a calling telephone equipment to a called telephone equipment, comprising the steps of:
-
receiving at a switching unit a data message transmitted by a telecommunications node connected to the calling telephone equipment; placing a first call from the remote switching unit to the called telephone equipment via the telecommunication network in response to the step of receiving; after the first call has been answered, placing a second call via the telecommunication network from the remote switching unit to the calling telephone equipment through the local telecommunications node; connecting the first and second calls; whereby the second call is not placed if the first call is not answered at the called telephone equipment so that costs attributable to the second call are not incurred unless the first call is answered at the called telephone equipment.

10. A method of connecting a calling telephone equipment to a called telephone equipment, comprising the steps of:
-
receiving at a local telecommunications node a first call placed from the calling telephone equipment via a telecommunication network; transmitting a data message from the local telecommunications node to a remote switching unit, the message comprising a telephone number of the called telephone equipment; and receiving at the local telecommunications node a second call from the remote switching unit after a third call from the remote switching unit to the called telephone equipment has been answered; whereby the second call is not received if the third call is not answered at the called telephone equipment so that costs attributable to the second call are not incurred unless the third call is answered at the called telephone equipment.
