Abstract: An architecture for connecting a call comprises a call processor, a signaling interface, a call process control system (CPCS), and an interworking unit. The signaling interface receives, transmits, and processes call signaling so that call signaling is received into, or transported from, the architecture through the signaling interface. The call processor processes the call signaling to select connections for calls. The CPCS receives data fills from translations, processes the data to be in a format compatible with the call processor, and fills the data into tables in the call processor. The CPCS also interfaces through the signaling processor with other systems, such as accounting systems and operations centers. The interworking unit interworks user communications between time division multiplex and asynchronous transfer mode connections and between time division multiplex connections and other time division multiplex connections.

Abstract: A gateway cluster has a number of gateways for different types of communication protocols. The respective gateways convert network messages to normalized messages by querying the categories, data, and network types of the normalized data for the mobile systems from which the network messages were generated. A database system stores normalized data in categories. The normalized data include data relating to the mobile systems and network types for the data. A unified mobility manager is coupled to and in communications with the gateway cluster and the database system. The unified mobility manager receives and processes the normalized messages, performs operations based on the normalized messages and on the categories, the data, and the network types of the normalized data, and formulates normalized responses responsive to the normalized messages. The normalized responses are converted to network responses at the gateways, and the network responses are sent to the respective mobile systems.

Abstract: A method for determining the name of a calling party where the calling party's name and corresponding telephone number are found in a remote database. The method first identifies whether the calling party's telephone number is contained within the local database. When it is determined that the telephone number is not within the local database, the method attempts to locate the telephone number in a remote database. A query is formed according to a basic signal transmission protocol to ensure that a database which receives the query will be able to respond to it. The query requesting the name associated with the telephone number is sent across a network. The method receives a response to the inquiry and checks to ensure that a name was returned to the local database before delivering the name to the called party.

Abstract: A method and system for integrating a computer and a telephone. A stimulus messaging device, such as an analog telephone, is provisioned as a functional messaging device, such as an ISDN telephone, at a switch. The switch communicates with the telephone through a loop interface device. The loop interface device translates ISDN messages destined for the telephone received from the switch into analog signals for the telephone. The loop interface device also sends the ISDN messages received from the switch to a computer associated with the telephone. The loop interface device translates analog signals received from the telephone into ISDN messages for transmission to either the switch and/or the computer. The present invention enhances call control information for an analog telephone and allows tight integration between a telephone and a computer.

Abstract: Method and apparatus for conducting surveillance in a SS7 Intelligent Network (IN) or Advanced Intelligent Network (AIN) provides in the case of AIN that an Info Analyzed trigger is armed in an end office switch and notifies a delivery function when a call is processed. The delivery function instructs the end office switch to forward the call to the delivery function, where it is accessed for monitoring forwarded back to the end office switch. A similar method is used to process calls received by the SUS. In the case of IN, the identity of a line card assigned to a subscriber under surveillance (SUS) is changed to a number dedicated to surveillance subjects. Calls originated by the SUS are forwarded to a delivery function, which identifies the SUS based on the dedicated number of the calling party, intercepts call content, and forwards the call back to the end office switch with the called party id and the original number and id of the SUS. The end office switch then completes the call.

Abstract: The system and method of the present invention completes at least two calls originating from terminal equipment located at a premises and connected by a point-of-attachment having a single phone number to a public switched telephone network where a dial tone is provided to the premises. Multiple calls are now allowed with an analog interface to the public switched telephone network. At least two calls and control channel are combined into a modulated analog signal having a separate channel for each call and transmitted through a modulation/demodulation device as a modulated analog signal to the public switched telephone network. The modulated analog signal is split into respective calls and control channel. Each call is forwarded to a respective remote device based on the identity information and auxiliary information received through the control channel.

Abstract: Apparatus and a method for controlling the establishment of telecommunications calls. In response to a service request from a calling party, a switch serving the calling party transmits a query identifying the called party to a shared database. The database provides information identifying the switch for accessing the called party, and information for identifying port(s) for accessing the called party from that switch. When a customer moves from one location to another, the database is updated to reflect the switch and port identification associated with the new location of the customer. If the called customer is a mobile customer, the database maintains information concerning the current location of that customer so that calls can be immediately switched to that customer.

Abstract: A system and method for connecting a call processes call signaling to determine if a call is a ported call or a non-ported call. A signaling processor determines if a ported number parameter (PNP), such as a forward call indicator (FCI) bit M and/or a ported number generic address parameter (GAP), is present. If the PNP is not present and the signaling processor determines the dialed number is a member of a portable number plan area and central office code combinations (NPA-NXX), the signaling processor queries a ported number database (PNDB). The PNDB responds with the called number dialed digits if the call is not a ported call or a location routing number (LRN) if the call is a ported call. The signaling processor appends a 1 to the nature of address (NOA) subfield of the called party number (CdPN) field if the call is a ported call.

Abstract: A second network such as an interexchange carrier advantageously identifies incorrect original number portability data from the first network such as a local telephone company and obtains new number portability data to prevent misrouted calls. The second network receives original number portability data from the first network. The second network determines whether to use the original number portability data from the first network for call routing. If the original number portability data from the first network is not used for call routing, the second network generates and transmits a query to obtain new number portability data for call routing. The second network receives the new number portability data for call routing in response to the query. The second network then generates and transmits a route instruction using the new number portability data.

Abstract: A system verifies and validates PSTN to IP Network services prior to the availability of the services to a plurality of subscribers. A PSTN call generator services a plurality of callers coupled to the PSTN and to a test database. An IP client simulator is coupled to the test database and to an IP Network. A data bus couples the PSTN and the IP Network to a registration server for registering the client and a heartbeat server for tracking the system for heartbeat message. An application server processes test service calls from the PSTN call generator whereby PSTN-IP Network services can be executed for all clients or individual clients as represented by the IP Client simulator for verification and validation of PSTN services to IP Network clients prior to the availability of the services to the clients.

Abstract: A system and a method store, display and report outgoing call log data associated with telephone calls from a subscriber's telephone. The system includes a switch in one network that receives a telephone call from the subscriber's telephone and launches a query in response to an AIN trigger to a service control point. In response, the service control point forwards associated call data to an interface server in another network via a generic data interface. The interface server obtains additional information from a directory database and sends the call data and the additional information to an outgoing call log database, which stores the call data and the additional information as the outgoing call log data. A web server retrieves the outgoing call log data and displays it to the subscriber at a web client.

Abstract: An element management system (“EMS”) interfaces between a telephone company computer or a terminal for use by a telephone company system administrator or customer service representative, and a telephone network element such as a central office or a group of central offices. In order to store and process subscriber data during the time periods when a telephone computer system is busy controlling telephone switching functions and therefore giving low priority to such data, the EMS contains a proxy database and maintains it between the periods when access to the telephone computer system is desired and available, without detrimentally involving the telephone computer system, the telephone switching network or any elements thereof. The EMS is capable of operating as the sole repository of subscriber data in a telephone computer system configured to operate in such an environment.

When the call is connected to the telecommunications relay service center, information that identifies the caller is reliably forwarded to the telecommunications relay service center.

Abstract: The invention is a system for providing virtual connections through an ATM interworking multiplexer on a call-by-call basis. A signaling processor receives signaling for a call and selects the virtual connection for the call. The signaling processor generates control messages that identify the selection and transfers the control messages to the ATM interworking multiplexer that accepted the access connection for the call. The multiplexer converts user information from the access connection into ATM cells for transmission over the virtual connection in accord with the control messages.

Abstract: A telecommunications method and routing system determines a routing preference and routing of a call from a calling party to a called party for a local service provider. The system includes a service control point that receives a signal from a switch. The switch recognizes at least one of a calling party number and a dialed number that indicates a type of service. The service control point determines the routing preference of the local service provider for the call based upon the type of service and a local service provider identifier associated with one of the recognized calling party number and dialed number.

Abstract: A bridge connection is made between the interfaces on physically distinct telecommunication servers such that the two ends of the bridge can be used to connect existing calls that are terminated on each of the servers. To provide the bridge connection, a call using a standard outgoing PRI trunk on one of the servers is made through the public switched telephone network (PSTN) to an incoming PRI trunk on the other server. When a bridge connection is required one of the servers is queried for its directory number, which is any number that the PSTN has assigned to equipment in that server. The other server is then instructed to make a call to that number. When the called server recognizes the incoming call as bridge connection, its answers the call. The calling server then associates the bridge connection with the pending action, using information encoded in the out-of-band signal with which the call between the servers was established.

Abstract: A service control point transmits a recharge request message or advice of charge to a mobile client resident in a wireless communications device. The message is first received by a wireless telephony application server that then forwards the message to a wireless access protocol gateway. The wireless access protocol gateway then sends the request to the mobile client. The user of the mobile client responds with an affirmative or negative answer to the request to recharge the prepaid telephone airtime account. The service control point then either recharges the account as instructed or lets the account expire, depending on the response from the user.

Abstract: The common channel signaling (CCS) system of the public switched telecommunication network involves digital call routing information that is communicated between the switches of the network and signal transfer points (STPs) of the CCS system and among the STPs themselves. The CCS system causes the network switches and the trunks that connect them to be so interconnected as to complete a connection between a calling party and a called party. The STPs are kept as close as practicable to the network switches so as to minimize the length of the digital transmission links between them. This results in a proliferation of less-than-optimally utilized STPs.

Abstract: A system in which centralized announcement platforms are connected to host switches over dedicated trunks, and remote switches needing announcement services send a signaling message to a host switch requesting a connection to the announcement platform. A connection is then established between the host switch and the remote switch over a regular trunk, and the full connection is completed over a dedicated circuit between the host switch and the announcement platform. Announcement message ID and other information required by the announcement platform is coded in the available parameter fields of a signaling message. Less total circuits are required and redundancy is provided.

Abstract: The invention includes a system for processing telecommunications signaling. Signaling for a call is received into a signaling processor.

The signaling processor is not coupled to a switch matrix and only communicates with the network elements over signaling links.

Abstract: When a leased line is incorporated in a virtual private network forming a composite communication network together with a public network, a service control point searches a data base to see what private branch exchanger is the closest to a caller, and establishes a communication path including the leased line in the composite communication network so that high quality economical communication is offered between the subscribers.

Abstract: A Service Control Point (SCP) directs a telecommunications network to connect a resource only when the resource is needed. When the resource is no longer needed, the SCP selects a new connection for the network. The SCP directs the network to disconnect the resource and use the new connection so the resource does not remain on the line during the entire call. The invention can be used to add and drop multiple resources from a call while the call is in progress. The SCP also provides context information for the call so multiple resources can access context information for the call.

Abstract: A method and system include routing telephone calls from multiple private networks via public lines and trunks in a public switched telephone network (PSTN) to a host switch, at which the connections would begin to run parallel. The host switch routes the telephone calls via a private trunk group to a private facility, such as an electronic tandem network (ETN) node or an asynchronous transfer mode (ATM) switch. If the private trunk group is full or unavailable, the host switch routes the telephone calls over alternate private or public trunk groups and selected carriers.

The system can include customer premise equipment (CPE) selectively connectable to a remote central office (CO), a packet-switched network gateway, such as an Internet telephony gateway (ITG), for remotely communicating service requests to a local service node. The local service node can be located within the service provider's territory and returns telephony service responses via the packet-switched network gateway to the remote CO, and ultimately the remote CPE.

Abstract: A line group function in a communications network based on ITU-T H.323 is implemented via a proxy function. First, an alias address for the line group is converted into a group transport address for a proxy function, and a connection setup message is transmitted from the calling endpoint to the proxy function using the group transport address. A connection setup message is transmitted from the proxy function to group endpoints in the line group using transport addresses known to the proxy function. After a response message has been transmitted from one of the group endpoints to the proxy function, the address of this endpoint is transmitted to the calling endpoint, and the address of the calling endpoint is transmitted to the responding group endpoint by the proxy function. A connection is set up between the calling endpoint and the responding group endpoint using the addresses of these endpoints.

Abstract: A system (100) and method deliver audible caller identification information when standard Caller ID information can not be provided, even when a subscriber to the service has per line blocking. A service control point (106) detects the directory number to which a terminating attempt trigger is assigned and places this directory number in a parameter for transmission to a service switching point (102) using a forward_call message (206). The per line blocking function does not interfere with transmission of this parameter so that the called party's directory number can be passed for processing and call completion by the system.

Abstract: An open architecture platform bypasses data from the facilities of a telecommunications carrier, e.g. an incumbent local exchange carrier, by distinguishing between voice and data traffic, and handling voice and data traffic separately. An SS7 gateway receives and transmits SS7 signaling messages with the platform. When signaling for a call arrives, the SS7 gateway informs a control server on the platform. The control server manages the platform resources, including the SS7 gateway, tandem network access servers (NASs) and modem NASs. A tandem NAS receives the call over bearer channels. The control server determines whether the incoming call is voice traffic or data traffic, by the dialed number, and instructs the tandem NAS how to handle the call. Voiced traffic is transmitted to a switch for transmission from the platform. Data traffic is terminated at a modem NAS, where it is converted into a form suitable for a data network, such as a private data network or an Internet services provider (ISP).

At least one call and control channel are combined into a modulated analog signal having a separate channel for each call and transmitted through a modulation/demodulation device as a modulated analog signal to the public switched telephone network. The modulated analog signal is split into respective calls and control channel. Each call is forwarded to a respective remote device based on the identity information and auxiliary information received through the control channel.

Abstract: A method (100) for preventing message looping in a telecommunications network (70) includes the steps of receiving a UDT/S query message, determining a next destination for processing the query message and a route for delivering the query message to the next destination (102). A determination is then made as to whether the route to the next destination is XUDT/S capable (104). The UDT/S query message is converted to an XUDT/S format by inserting a hop counter (38) therein if the route is XUDT/S capable (108). The query message is then delivered to the next destination via the route (110). The hop counter (38) in the query message is then decremented at the next destination in response to receiving a message of the XUDT/S format (112). A message loop error is recognized and processed when the hop counter (38) reaches a predetermined value.

Abstract: A signal state management (SSM) system avoids both the overhead of maintaining call state and complex signaling in a packet network gateway, while simultaneously providing a more scalable system by not placing too great a state or processing burden on the signaling or call processing server. The SSM system sends an event/action table from a call agent to the gateway that directs the gateway to detect and accumulate specified signaling events generated by a telephone. The gateway accumulates the signaling events according to the event/action table and notifies the call agent only when the signaling events specified in the event/action table are detected. The call agent then sends a new event/action table to the gateway that commands the gateway to detect and accumulate a new set of signaling events. After notifying the call agent, the gateway operates in a quarantine where all signaling events are queued.

Each call is forwarded to a respective remote device based on the identity information and auxiliary information received through the control channel.

Abstract: For complementing a telephone connection with additional information a first telecommunication device transmits to a second telecommunication device a request for setting up a telephone connection (102, 302, 402). In association with said request, a first signalling message (103, 303, 403) is transmitted. The receiver of the first signalling message (104, 304, 404) makes a decision about how to handle the call on the basis of the information received in said first signalling message (105, 305, 405).

Abstract: An enhanced application switched telephone network and a method of completing calls using the network are described. In the enhanced application switched telephone network, every switching office is connected to at least one enhanced ISUP voice-grade trunk. A link set and a route set associated with the enhanced trunk route common channel signaling messages associated with calls directed to the enhanced trunk(s) to a call control node. The call control node is thereby enabled to exercise control over those calls. The advantages include point of origin call control, enhanced application service development, rapid service deployment and significantly more efficient use of PSTN facilities.
