Abstract
A method and system for optimizing telecommunications network resources using a feedback control system. In particular, a call screening device is used in conjunction with a signal switching point to accept or reject incoming phone calls based on far-end capacities of terminating carriers or invalid calling codes in the calling numbers as indicated by signaling messages from terminating carriers.
Claims24
A call screening system for use in a telecommunications trading environment, comprising:
- a. a node for matching buyers and sellers of telecommunications services based on buy and sell orders for said telecommunications services, said node being in signaling communication with networks of the buyers and sellers and processing signaling messages between buyers and sellers relating to status of transmitted telephone calls;
- and
- b. a screening processor for screening telephone calls originating from the buyers based on said signaling messages such that telephone calls that are not associated with the matched buy orders are released back to corresponding buyers' networks.
A method of screening telecommunications traffic in a telecommunications environment, comprising the steps of:
- a. receiving buy and sell orders for telecommunications services from buyers and sellers;
- b. matching buyers and sellers of telecommunications services based on the buy and sell orders for said telecommunications services;
- c. processing signaling messages between buyers and sellers relating to status of transmitted telephone calls;
- and
- d. screening telephone calls originating from the buyers based on said signaling messages such that telephone calls that are not associated with the matched buy orders are released back to corresponding originating buyers networks.
A call screening system for use in a carrier-to-carrier environment, comprising:
- a. a host carrier node for receiving and transmitting from a first carrier telephone calls to a second carrier, said host carrier node being in signaling communication with said first and second carriers and processing signaling messages from said second carrier relating to status of transmitted telephone calls;
- and
- b. a screening processor for screening telephone calls originating from said first carrier based on said signaling messages.
A method of call screening in a carrier-to-carrier environment, comprising the steps of:
- a. processing signaling messages to and from a first carrier and a second carrier relating to status of transmitted telephone calls;
- and
- b. screening telephone calls originating from said first carrier based on said signaling messages.
