Patent number: 5940491Abstract: Apparatus and method for controlling establishment of telecommunications call connections in a telecommunications network. The network comprises a plurality of switches each with its own switching processor means, and a plurality of switching processing platforms each comprising at least one call processor. The switches and switching processing platforms are interconnected by a data network. SS7 signaling messages are received in one of the platforms and a call is assigned to a call processor. The call processor communicates with one or more switching processor means for controlling establishment of the call. Call features are processed under the control of the call processor. Advantageously, any call processor can be used for serving any call in the network and can control all legs of a multi-leg connection. Advantageously, in a large network, the number of platforms may be significantly less than the number of switches which reduces the cost and complexity of administration of the network.Type: GrantFiled: February 29, 1996Date of Patent: August 17, 1999Assignee: Lucent Technologies Inc.Inventors: Thomas Wayne Anderson, Alan Eugene Frey, Michael Neal Meyers

Patent number: 5903638Abstract: A telecommunications system for international routing processes international calls directed to a multi-carrier country. A network control system provides the intelligence needed to weigh all of the applicable information and, based on International Traffic Bid Allocation, returns the routing information to the long distance carrier domestic switch in accordance with an agreement on call allocation between the long distance carrier and the international carrier in the multi-carrier country. Based on the routing information provided by the network control system, the domestic switch subsequently routes the international call to the proper terminating gateway switch and the destination multi-carrier country.Type: GrantFiled: October 25, 1996Date of Patent: May 11, 1999Assignee: MCI Communications CorporationInventors: William G. Welter, Jr., Louis G. Gottlieb, Emery J. Reistetter, Eva Marcus-Kantor, Ronald J. Settele

Patent number: 5844981Abstract: A method and system of improved routing to WATS completes calls through a wide area telephone service using indirect routing. When a call is placed from a calling telephone station to a called telephone station, a telephone network attempts to route the call from the originating switch, on which the call entered the network, to a local exchange carrier serving the called station. If other routing paths in the network are unavailable or unsuccessful, a network processor recommends a routing from the originating switch to the local exchange carrier through a tandem switch and the WATS line of another telephone network. This capability provides a reduced incidence of blocked calls, such as may result from telecommunications system outages.Type: GrantFiled: November 27, 1995Date of Patent: December 1, 1998Assignee: MCI Communications CorporationInventors: Donald Pitchford, Howard McNeil

Patent number: 5815559Abstract: In an automatic message accounting (AMA) record distribution network, a method and system for sorting AMA records by using an area code or numbering plan area (NPA) data array and directory number bit maps to identify AMA records which are of interest to an operation center. Operation centers have access to every AMA record generated by a toll switching network and are initialized with a table of AMA structure and call-type codes, an NPA data array and directory number bit maps. NPA entries in the data array which are of interest to a particular operation center contain pointers (i.e., memory address locations) of the directory number bit maps. As AMA records are received by the operation center, directory numbers which have NPAs of interest to the operation center are compared to directory number bit maps. A directory number of an AMA record which corresponds to a numbered bit position of the directory number bit map is processed by the operation center.Type: GrantFiled: August 28, 1997Date of Patent: September 29, 1998Assignee: Lucent Technologies Inc.Inventor: Andrew Thomas Schnable

Patent number: 5787150Abstract: Method and apparatus allow a caller to contact a called party with a collect call whether or not the called station is answered or is busy. When the caller dials a collect call access code, the call is routed to a messaging platform which collects the call information and attempts to complete the call. If there is no answer or if the called station is busy, the messaging platform retains control of the call and automatically prompts the caller to enter a name and a message to be delivered to the called party. After the name and message have been entered, the caller is given a confirmation number, if desired, which allows the caller to determine whether the called party has received the message. The messaging platform repeatedly attempts to deliver the message by calling the called party. Upon the call being answered, the messaging platform identifies the caller and prompts the called party to accept or refuse the collect message.Type: GrantFiled: December 29, 1995Date of Patent: July 28, 1998Assignee: MCI Communications CorporationInventors: Doug Reiman, Rick L.

Patent number: 5754633Abstract: A party (12, 14, 16 and 18) to a telephone call carried by a telecommunications network (10) may effect transfer of the call charges that would otherwise be billed to that party by entering a billing transfer request after the call has been set up. Upon receipt of the billing transfer request, the network verifies whether the subscriber is authorized. If so, then a billing record created upon call set up is transferred to an alternative number designated by the subscriber.Type: GrantFiled: May 31, 1996Date of Patent: May 19, 1998Assignee: AT&TInventor: Robert Bergman Levy

Patent number: 5539817Abstract: A method of providing multi-switch business group (MBG) services at each of a plurality of locations is described. The MBG services can be provided for calls made from a calling party served by an originating switch at one location to a called party served by a terminating switch at a location serviced by an inter-exchange carrier (IEC). When the calling party goes off-hook, a determination is made of whether the call is made from a centrex line. Digits dialed by the calling party are then collected at the originating switch. A determination is then made of whether the dialed digits contain an access code indicative that the call is to be routed to one of the plurality of locations which is served by an IEC. If the call is to be routed via an IEC, the initial address message (IAM) required for IEC calls, is modified to include MBG service information. This will permit MBG services to be offered between the calling party and the called party over public CCS7 trunks routed via an IEC.Type: GrantFiled: December 11, 1995Date of Patent: July 23, 1996Assignee: Stentor Resource Centre, Inc.Inventor: Douglas B.
