Patent number: 5903636Abstract: A system and method for providing calling party identification information to a called party in an intelligent network. A long distance calling card company maintains a subscriber database that includes preferred calling number data and calling name data for each subscriber. When a subscriber places a calling card call, the service provider looks up the subscriber's database record, retrieves the preferred calling number data, and sends the calling number data to the terminating end office. A calling name query from the terminating end office is routed to a database that includes data from the service provider's subscriber database. The caller's name is retrieved and returned to the terminating end office and displayed on the called party's display device, along with the calling number data, date, and time.Type: GrantFiled: October 27, 1997Date of Patent: May 11, 1999Assignee: BellSouth CorporationInventor: Dale W.

Patent number: 5883943Abstract: A telecommunications system and method for either displaying the calling party name, if available, to the called subscriber at the time of call setup, or informing the called subscriber that a name query is being performed if the calling party name is not available at call setup. If the calling party name is not available at the time of setting up of the call, the call is setup with the display reading "Searching Name". This gives the option to the subscriber to either pick up the call without the name information, or to wait for the name information to arrive. If the name is found, it will be displayed as such; if not, the display will read "out-of-area" (or other similar message). Advantageously, embodiments of the present invention do not increase the call setup time, while at the same time, the called subscriber has the option to wait for the Calling Party Name query response.Type: GrantFiled: November 6, 1997Date of Patent: March 16, 1999Assignee: Ericsson Inc.Inventor: Aqeel Ahmed Siddiqui

Patent number: 5878123Abstract: A telephone system and method that enables a telephone to handle more call appearances that it has call appearance keys. The telephone system contains a display and general purpose keys that are used to respond to prompts shown on the display. When the telephone system receives an incoming call that is not assigned to a dedicated call appearance key, then the system places a prompt on the display. The prompt identifies the line upon which the telephone call is received by placing an identifying name, number or telephone location on the display. The prompt is placed adjacent to one of the general purpose keys so that the prompt is clearly associated with only one of the general purpose keys. The system then assigns that general purpose key to the telephone line addressed by the prompt. As a result, the general purpose key becomes a call appearance key and a person using the telephone system can complete a connection between that telephone an incoming call by pressing that general purpose key.Type: GrantFiled: February 28, 1997Date of Patent: March 2, 1999Assignee: Lucent Technologies Inc.Inventor: Edward W.

Patent number: 5694459Abstract: A high-speed information service system is provided which uses a unique identifier received during call setup to retrieve automatically a personalized profile for an information service subscriber. The identifier uniquely identifies the subscriber, thereby allowing the information retrieval process to begin immediately after the call is setup. The system utilizes Integrated Services Digital Networks (ISDN) signaling and temporary, "out-of-band" signaling to improve information retrieval capability. ISDN signaling permits electronic addressing of information requested by the subscriber, thereby eliminating the delays which accompany DTMF signal processing. Communications between an information service provider and an individual information source are conducted using out-of-band signaling. That is, call setup and information request are processed using a channel other than the channel which carries data between the information service provider, the information source and the subscriber.Type: GrantFiled: January 16, 1997Date of Patent: December 2, 1997Assignee: AT&TInventors: Marjorie Susan Backaus, Claire Darcelle Barrera, Esther Lee Davenport, Harold Fahrer, Barry Norman Ostroff, Robert Petrelli, Susan Kay Sonke

Patent number: 5590184Abstract: A telephone subscriber of a privacy communications service is allowed to use a randomly selected non-assigned telephone number--instead of the subscriber's real telephone number--as a return phone number in a telephone message left for a called party. The non-assigned, randomly selected telephone number becomes inoperative after a threshold that may be pre-imposed by the subscriber is exceeded. According to a feature of the invention, the function of randomly selecting a non-assigned telephone number may also include replacing the calling party number with the randomly selected number. Hence, when a caller-id display unit receives the telephone number of an incoming call for which the privacy communications service is used, the randomly selected telephone number--as opposed to the real telephone number--is received and recorded by the caller-id display unit.Type: GrantFiled: March 3, 1995Date of Patent: December 31, 1996Assignee: Lucent Technologies Inc.Inventor: Thomas B.

Patent number: 5289542Abstract: Telephone call identification service that safeguards the privacy of an originating station (calling party), while providing useful identifying information to a destination station (called party), is achieved by an encryption process. The encryption process includes combining the originating number with the telephone number of the destination station to form a message. Thereafter, the message is encrypted using the Data Encryption Standard (DES) or the Rivest, Shamir, Adleman (RSA) encryption algorithm to form ciphertext which is transmitted to the destination station. Using either encryption process, the ciphertext is reversible. A telephone switching office, preferably equipped with an electronic program-controlled switching system, executes the encryption algorithm and safeguards the keys used for encryption and decryption. When reversibility of the ciphertext is deemed to be undesirable, the telephone switching office uses modulo n processing of the ciphertext to render it non-reversible.Type: GrantFiled: March 4, 1991Date of Patent: February 22, 1994Assignee: AT&T Bell LaboratoriesInventor: William K.

The caller's identification data is confirmed using various techniques and callers may be ranked and accounted for on the basis of entitlement, sequence or demographics. Callers are assigned random designations that are stored along with statistical and identification data. A break-off control circuit may terminate the computer interface aborting to a terminal for direct communication with an operator. Real-time operation processing is an alternative to stored data. The accumulation of stored data (statistical, calling order sequence, etc.) is variously processed and correlated as with developed or established data to isolate a select group or subset of callers who can be readily identified and reliably confirmed.Type: GrantFiled: December 3, 1991Date of Patent: October 19, 1993Assignee: First Data Resources Inc.Inventor: Ronald A.

Patent number: 5251255Abstract: This invention relates to arrangements for controlling processing of telephone calls from feature processors. Feature processors are data bases, usually shared among a plurality of switching systems, and usually comprising data for customers served by these switching systems, for altering the processing of telephone calls from and to these customers in accordance with that data. In order to perform this modification, data messages are exchanged between the switching systems and the feature processor. In a departure from the prior art, these data messages include functional indicators, i.e., indicators of basic characteristics of a call, each of which may be associated with many features and which may influence the execution of other features, wherein the execution of at least some of the features of the two groups can be influenced by the feature processor. Advantageously, the use of functional indicators helps to reduce the amount of data to be transmitted between the switching systems and feature processor.Type: GrantFiled: April 17, 1991Date of Patent: October 5, 1993Assignee: AT&T Bell LaboratoriesInventor: Robert V.

Patent number: 5166971Abstract: A method and apparatus for speaker recognition in a telephone switching system. For a speaker recognition in a system particularly fashioned as an ISDN communications system, speech specimens are input into a telephone terminal equipment (T1, T2) and are pre-processed there, being, in particular, sampled with a sampling rate that is greater in comparison to the standard sampling rate. The samples are intermediately stored in the telephone terminal equipment (T1, T2), are read-out with the standard sampling frequency and are transmitted to a switching system (VA) in which the actual speaker recognition (SPR) is carried out.Type: GrantFiled: February 24, 1992Date of Patent: November 24, 1992Assignee: Siemens AktiengesellschaftInventor: Emmeran Vollert

Patent number: 5121423Abstract: A communication unit utilizes a caller management unit which monitors in-house lines and detects a caller side calling code included in a calling set up message applied at the time of reference. A control unit stores the detected calling code in one memory region of a memory and reads out the stored calling code from the memory region in response to an output request to produce information corresponding to the calling code. The management unit displays the information produced by the control unit. The memory has another memory region for storing a plurality of predetermined calling codes and caller specification information corresponding to each calling code. The control unit stores the detected calling code into the one memory region in response to a non-response detection to reference by the line monitor.Type: GrantFiled: July 10, 1990Date of Patent: June 9, 1992Assignee: Sharp Kabushiki KaishaInventors: Katsurada Morihiro, Shimonaga Sadaaki

Patent number: 5029202Abstract: An incoming telephone call director is intended for use with a Ring-Master service which provides different ring signals on a single telephone line to selectively access one of several devices on the line. The call director ignores a first ring, counts the pulses in the next ring, and then directs the next subsequent ring to a selected telephone or device such as a computer modem, facsimile, telex, etc., on the single telephone line. A different sounding ring signal is used to identify and access each telephone or device on an individual basis. The call director senses an Off-Hook condition for the telephone or any one of the devices and connects that device to the single telephone line to provide a Dial Tone to permit a plurality of such devices to share a single telephone line without interfering with each other or telephone calls on the line.Type: GrantFiled: March 19, 1990Date of Patent: July 2, 1991Inventors: Robert C.

Patent number: 4959856Abstract: Administration of a communication system having a plurality of addressable communication ports is accomplished automatically, by the system itself. The system is initially provisioned only with unlinked terminal translations. Establishment of hardware translations and their linking to the terminal translations is accomplished by the system automatically, in response to initial calls from system users. Each one of these initial calls informs the system of the call-originating terminals's extension, and thereby specifies to the system the requisite information for linking the originating extension and terminal translation with the call's incoming port. Station moves are also accomplished automatically, through similar calls.Type: GrantFiled: May 4, 1989Date of Patent: September 25, 1990Assignee: AT&T Bell LaboratoriesInventors: Raymond B.
