| 281 | Method and apparatus for processing telephone calls | US439256 | 1995-05-11 | US6122484A | 2000-09-19 | Robert M. Fuller; Frederick A. Epler; Maxwell E. Manowski |
| The invention provides an apparatus and method for processing incoming telephone calls directed to a user. A valid identification signal from the user is detected and then the user is transferred to a system command mode. In the command mode, a request from the user for information regarding a present mode by which incoming calls are processed is identified, the current mode by which incoming calls are processed is recalled from memory, and the results are transmitted to the user. | ||||||
| 282 | System and method for application location register routing in a telecommunication network | US467659 | 1999-12-20 | US6097960A | 2000-08-01 | Rajan Rathnasabapathy; Russell R. Cook |
| A system and method for application location register routing at a signal transfer point (26) are provided. The signal transfer point (26) includes processor clusters (64, 66, 68) and databases (236, 238) for processing queries including global title translation, local number portability, and application location register routing. A query message is received by the signal transfer point (26), a first database residing in the signal transfer point (26) is accessed to determine the location of a second database (238) also residing in the signal transfer point for processing the query message. The second database (238) is then accessed to obtain the network address of a home location register or short message service center, which is then used to deliver the query message to the network node specified by the network address. | ||||||
| 283 | Dynamically controlled routing using dynamic management of intra-link traffic to virtual destination nodes | US817786 | 1997-04-24 | US6091720A | 2000-07-18 | Fran.cedilla.ois Bedard; Jean Regnier; France Caron |
| A DCR telecommunications network comprises a plurality of network switching elements interconnected by circuit groups for carrying calls, and a network processor communicating with the network elements. If it cannot use a direct route to a neighbouring network element, the switching element may access a routing table containing alternate routes which are updated periodically by the network controller. The network functions as a group of nodes interconnected by links. Routing takes place on a node-to-node basis. At least one of the nodes is a virtual destination node, vis. a logical entity corresponding to a group of two or more components which are network elements. A link to the virtual destination node is a set of circuit groups connecting to its components. Final destinations outside the network can be associated with the virtual destination node as an intermediate destination node, thereby allowing a call to exit the DCR network via any of the components rather than via only one Unique Exit Gateway. Where a link to the virtual destination node comprises a plurality of circuit groups, the associated switching element stores proportions for those circuit groups. When attempting to route a call via the link to the virtual destination node, the switching element attempts the circuit groups in dependence upon the proportions. The proportions may be fixed, i.e. computed off-line and stored. Alternatively, the proportions may be updated by the network processor based upon call completion information it receives periodically from the switching elements. | ||||||
| 284 | Method for updating a local switch internal database in a system having different service providers within a common numbering plan area | US967223 | 1997-10-29 | US6078656A | 2000-06-20 | Edward Sonnenberg |
| A method for enabling a plurality of Local Service Providers within a common Numbering Plan Area (NPA) to serve Subscribers of the plurality of Local Service Providers. The method includes the step of assigning to each Subscriber of a Local Service Provider within the common NPA a unique three digit code, hereinafter referred to as a SPA code. The service provider area (SPA) code is used by the telephone system in the same manner presently used for routing calls made when a calling Subscriber dials the NPA code of the called party. Here, however, the SPA code is not dialed by the calling Subscriber. The dialed directory number, NXX-XXXX, of a called Subscriber subscribed to a different Local Service Provider, is sent to a database. The database maintains a record of the relationships between the directory numbers of Subscribers and the SPA codes of the Subscribers. The database retrieves the SPA code associated with the dialed directory number presently serving the called Subscriber. The call is routed as SPA-NXX-XXXX. Because the ten digit format, SPA-NXX-XXXX, is the same as the present NPA-NXX-XXXX, ten digit format, existing signaling and routing mechanisms may be used to route the call. Thus, each one of the Subscribers of each one of the plurality of Local Service Providers is assigned a common SPA code, each one of the Local Service Providers having a different SPA code. | ||||||
| 285 | Communicator for a telephone system | US436593 | 1995-05-08 | US6067443A | 2000-05-23 | Robert M. Fuller; Frederick A. Epler; Maxwell E. Manowski |
| A communication system for coupling incoming calls from a calling party to a called party. The system includes at least one paging device and a plurality of other communications devices associated with prospective called parties, each of the other communications devices possessing communications capabilities different from the paging device. A programmed computer is responsive to signalling information in an incoming call for determining which paging device is associated with the called party and for determining which of the other communications devices is associated with the called party. An alerting signal is coupled to that paging device to alert the called party of the incoming call and a signal transmitted by the called party is detected in order to control further processing of the incoming call. | ||||||
| 286 | Method of routing emergency calls | US156278 | 1998-09-17 | US6067356A | 2000-05-23 | Wolfgang Lautenschlager; Hartmut Weik; Lothar Krank; Uwe Stahl |
| A method of routing a call, especially an emergency call made to a uniform regional or national central phone call number, which is made by a telecommunications (TC) subscriber in a publicly accessible digital TC network, to the respective geographically responsible call center, includes the steps of transmitting, as part of a calling signal, an identification of the TC subscriber making the call, using the subscriber identification to retrieve, from a database containing at least a geographic location associated with each subscriber, the location of the calling subscriber, selecting a responsible call center nearest the location of the calling subscriber, and routing the call from the subscriber to the nearest responsible call center. The method has the advantage that, in spite of possible breakdown of previous associations between telephone number prefixes and geographic locations, the subscriber's location can be reliably determined with the help of a central calling number/location data base, and the call can be routed to the respective geographically responsible call center. | ||||||
| 287 | Telecommunications network with portability of mobile subscriber number | US764634 | 1996-12-11 | US6064887A | 2000-05-16 | Karl-Erik Kallioniemi; Mikael Larsson; Bjorn Olsson; Per-Erik Mikael Kilhage |
| A telecommunications network (10) comprises a set of service provider/operator domains (20), including mobile telecommunications domains (20A-20C). A call-originating domain (20F) accesses a mobile subscriber number portability database (30F) to obtain the address of the gateway node (GMSC) of the telecommunications domain which currently serves a called mobile subscriber having a mobile station (70), and optionally the address of the home location register (HLR) of the called mobile subscriber. The address of the gateway node obtained from the database (and optionally the address of the home location register) are included along with the directory number (MSISDN) or IMSI of the called mobile subscriber in a routing message for completing the call. When changing service providers (e.g., changing to a new domain), the mobile subscriber number portability database is updated to reflect the change. Access of the database and usage of the address of the gateway node of the new domain in the routing message permit the mobile subscriber to retain the same MSISDN when changing service providers. | ||||||
| 288 | Method of enhancing call processing in a number portability environment | US861755 | 1997-05-22 | US6058313A | 2000-05-02 | Lev Slutsman; Kamlesh T. Tewani; Lance Wayne Wilson |
| A method is provided which reduces post-dial delay in a number portability environment. In particular, a switching office which controls call routing to portable numbers (NPA-NXXs) contains a cache for which location routing number response information may be stored. The processing office concurrently checks the cache for LRN response information corresponding to the dialed number and launches a query to a number portability database. Thus, if the LRN response information in the cache is valid then the call will be routed in the timeliest manner. However, if either the cache does not have any LRN response information or the LRN response information in the cache proves not to be valid then, the switching office will have received the LRN response information from the database more quickly based on the concurrent launching of a query. Therefore, a more timely attempt at establishing a proper connection to the dialed number will occur thereby reducing post-dial delay. | ||||||

| A system and method of providing CCBS services over GVNS. In a network service with routing code recalculation, a supplementary subscriber service involves an interaction between two subscribers. Knowledge of a subscriber access code, used in a called subscriber local remote exchange, is required in a calling subscriber local exchange. A subscriber access code is generated by modification of a called subscriber routing code, used by the calling subscriber local exchange. The modification occurs in a transit node of the network service. An interworking problem is then overcome by providing a relay CCBS application service element (CCBS-ASE), in a GVNS transit node, and arranging for end-to-end signaling to be replaced by two TC dialogs, one being the calling parties LE and the relay CCBS-ASE and the other between the called parties LE in the relay CCBS-ASE. | ||||||
| 290 | Interactive call identification | US632860 | 1996-04-16 | US6041103A | 2000-03-21 | Thomas F. La Porta; Arun N. Netravali |
| A method and apparatus for interactive call identification of a call to a called party. Identifying messages, either text and voice, can be entered on a call-by call basis by the calling party to provide information regarding the call to enable the called party to screen the incoming call. Such identifying messages can include descriptive information about the identity of the caller, the subject matter of the call or any other user-user information. The identifying message is transmitted in the form of a real-time message sent by the caller and received by the party being called in advance of their accepting the call. The identifying message is created on a call-by-call basis by the calling party. The called party receives the identifying message and, after receiving the message, the called party can accept, forward or reject the incoming call based on the information provided in the identifying message. The calling party has the option of using either real-time or pre-recorded message functions. The calling party can select, via a predetermined access code to enter a personal message (voice or text) directly from the location from which the call is being placed after dialing the desired number. Interactive call identification can be initiated either by the called or calling party. | ||||||

| The invention comprises a telecommunications signaling processor that processes Signaling System #7 (SS7) telecommunications signaling messages to select Asynchronous Transfer Mode (ATM) virtual connections and provide control messages indicating the selected ATM virtual connections. | ||||||
| 292 | ATM gateway system | US123162 | 1998-07-27 | US6026091A | 2000-02-15 | Joseph Michael Christie, deceased; by Joseph S. Christie, legal representative; by Jean M. Christie, legal represenative; Albert Daniel DuRee; Michael Joseph Gardner; Tracy Nelson; William Lyle Wiley |
| The invention is a system for modifying the VPI/VCIs in ATM cells transferred between two ATM systems on a call-by-call basis. A signaling processor receives signaling for the call and selects a new VPI/VCI for the call. The signaling processor generates a control message that identifies the old and new VPI/VCIs and transfers the control message to an ATM gateway. The ATM gateway modifies the old VPI/VCI in the ATM cells to the new VPI/VCI. | ||||||
| 293 | Portability of non-geographic telephone numbers of intelligent network services | US764633 | 1996-12-11 | US6002759A | 1999-12-14 | Karl-Erik Kallioniemi; Mikael Larsson; Bjorn Olsson |
| A telecommunications network (10) comprises a set of telephone service operator domains (20), including domains (20A-20C) having intelligent network-type services having non-geographic telephone numbers. A call-originating domain (20G) accesses a non-geographic service number database (30G) to obtain address information concerning the domain which currently handles the called service (90). The address information obtained from the non-geographic service number database includes the address a node in the domain which handles the service, e.g., the address of a gateway node (GW), and optionally the addresses of a service switching point (SSP), a service control function (SCF), and a service data function (SDF) which handles the called service (90). When changing telephone service operators (e.g., changing to a new domain), the non-geographic service number database is updated to reflect the change. Access of the database and usage of the addresses obtained therefrom in the routing message permit the service (90) to retain the same directory number when changing telephone service operators. | ||||||
| 294 | Call center integration with operator services databases | US833997 | 1997-04-11 | US5987116A | 1999-11-16 | Robert W. Petrunka; Joseph Bosco |
| A call servicing system allows service agents to service calls from customers. The system includes local customer switches, local agent switches, and a customer database connected to a network call center. The local customer switches direct calls to and from the customers and the local agent switches direct calls to and from the service agents. The customer database stores information regarding the customers sending the calls. The network call center receives a call from a first one of the customers, queries the customer database to retrieve customer information corresponding to the first customer, and concurrently routes the customer call and the corresponding customer information to one of the service agents. | ||||||
| 295 | Intelligent, high-speed switching matrix | US918457 | 1997-08-26 | US5953329A | 1999-09-14 | Andrew McKinney Degges; Michael Paul Overcash; William Douglas Alexander; Eugene Harold Kreeft |
| A switching system and a method for performing high-speed switching within a telecommunications system. One aspect of the present invention utilizes an internal host and a self learning routing algorithm to reduce the time required to identify an output channel for routing a communication. Thus, the overhead associated with querying an external database can be eliminated from the switching system allowing a switching system to reduce the call hold time, and thereby meet the call flow demands of the telecommunications system. Another aspect of the present invention is the use of a hashing algorithm in resolving routing decisions. The hashing algorithm operates on received DID numbers to identify an output channel for a received call. The hashing algorithm is able to accept any DID number as input. Therefore, this aspect of the present invention allows a switching system to quickly resolve routing decisions without requiring consecutive DID numbers. This aspect of the present invention also allows a switching system to perform true, ten digit portability of DID numbers. Another aspect of the present invention is buffering the data between various components of the telecommunications system to eliminate problems due to skew between the transmission clocks of the various components. This aspect of the present invention allows the transmission of the data to be delayed by at least one frame length and then uses the clock rate of the destination component to ensure that clock skew is eliminated. | ||||||
| 296 | Management of calling name delivery in telephone networks providing for telephone number portability | US914670 | 1997-08-18 | US5949865A | 1999-09-07 | Lynn H. Fusinato |
| A system and a method for managing calling name (CNAM) queries in a plurality of telephone networks including a plurality of subscribers each assigned a telephone number in a predetermined number series associated with a particular switch in one of the telephone networks, wherein at least one of the number series is a portable number series including telephone numbers assigned by one network but connected to another network. According to the present invention, if the calling party number (CgPN) belongs to a portable number series, gapping will be applied to CNAM queries containing either portable telephone numbers associated with a location routing number (LRN) identifying the switch and network to which the CgPN is connected, or non-portable telephone numbers belonging to the same number series as the LRN. On the other hand, if the CgPN does not belong to a portable number series, gapping will be applied to CNAM queries containing telephone numbers belonging to the same number series as the CgPN. | ||||||
| 297 | Global title translation in a telecommunications signalling network supporting local number portability | US803052 | 1997-02-19 | US5940492A | 1999-08-17 | James Robertson Galloway; Douglas John Carson; Salih Kabay; Peter John Mottishaw |
| A method is disclosed that avoids the need to enlarge the translation tables held by Signal Transfer Points (STPs), for the purpose of effecting global title routing of certain signalling messages to enable number portability. Signalling links are monitored to detect messages needing to be routed by global title; the global title of each such message is then checked to see if it relates to a ported number and if this is the case, the global title is modified to a number that will result in the appropriate routing of the message on the basis of the existing translation tables of the STPs. | ||||||

| A call reservation technique of a first exchange serving a call of an outgoing subscriber and a second exchange serving a call of an incoming subscriber includes: outputting a message requiring a call reservation registration from the first exchange to the second exchange at the time of reserving the call, and in the second exchange, storing call reservation information according to the message requiring the call reservation registration, the second exchange being transferred to a state of the call reservation registration in response to the message requiring the call reservation registration and simultaneously outputting a call reservation registration response message, and in the first exchange, storing the call reservation information according to the call reservation registration response message and the first exchange being transferred to a state of a call reservation; and checking the state of the incoming subscriber in the state of the call reservation registration in the second exchange and then inputting the message requiring the call reservation service to the second exchange when the incoming subscriber is in an idle state, and checking the state of the outgoing subscriber according to the message requiring the call reservation service in the first exchange and then forming a calling path of the outgoing subscriber and the incoming subscriber in the first exchange and the second exchange and processing the call, when the outgoing subscriber is in the idle state. | ||||||
| 299 | Systems and methods for providing enhanced services for telecommunication call | US754847 | 1996-11-22 | US5920562A | 1999-07-06 | Joseph Michael Christie, deceased; Joseph S. Christie, legal representative; Jean M. Christie, legal representative; Tracy Lee Nelson |
| A system and method provide enhanced services for a call that is transported from a communication device through an asynchronous transfer mode system. The call has user communications in asynchronous transfer mode cells and call signaling. A signaling processor receives the call signaling and processes the call signaling to determine a connection to a service platform. The signaling processor transports a processor control message designating the selected connection. An asynchronous transfer mode interworking unit receives the user communications from the communication device and the processor control message from the signaling processor. The asynchronous transfer mode interworking unit converts the user communications from the asynchronous transfer mode cells to a format compatible with the service platform and dynamically transports the user communications to the service platform in real time. The service platform processes the user communications. The reverse process can also take place with the dynamic transfer, in real time, of the processed user communications back to the communication device in asynchronous transfer mode cells that identify the connection to the communication device. | ||||||
