Abstract: A service execution environment for an advanced interactive voice response (IVR) service node. The service execution environment functions within a next generation service node (NGSN) IVR platform in a telecommunications network. The environment uses individual service-independent building blocks (SIBBs) that allow the creation of customer applications with simple references to the individual primitive SIBBs or composite SIBBs, with branching available. Functional calls to a sequence of SIBBs along with customer specific data stored in a database comprise a complete customer application. When a call is received by an IVR service node, the application is executed by calling the SIBBs to apply certain treatments to the call. The use of the SIBBs allows increased efficiency in the network because calls can be routed to any NGSN node. Each NGSN needs no customization to perform a particular customer application.

Abstract: A method of providing a user the option to accept an incoming call, play a prerecorded message to the incoming party, ignore the incoming call or forward the incoming call to a separate telephone number is disclosed for use when the user is connected, via the same telephone line, to the Internet. The disclosed invention reduces the number of times the incoming call is transferred which reduces the number of reserves used in processing the incoming call. This reduction frees up system resources and allows overall system resources to be used more efficiently.

Abstract: A routing node for translating and re-directing Signaling System 7 (SS7) messages associated with ported subscribers in a communications network is disclosed. Re-direction or re-routing of signaling message packets is accomplished without the need for explicit local number portability (LNP) type triggers or queries, and as such the routing node of the present invention is considered to implement a triggerless LNP routing solution. Upon entering the routing node, SS7 ISDN User Part (ISUP) type signaling messages that require LNP translation service are encapsulated in an SS7 Signaling Connection Control Part (SCCP) message packet and internally routed within the switch to an LNP translation subsystem. The LNP translation subsystem can be integrated within the routing node or a portion of the LNP translation subsystem can be located on an external database server platform. LNP translation involves the lookup of a called party address in an LNP database, and the return of a Location Routing Number (LRN).

Abstract: A system and method include implementing and accessing a subscriber's telecommunications services, using a graphical user interface (GUI) via the Internet, and an interactive voice response (IVR) system via the public switched telecommunications network (PSTN). The system and method enable a subscriber to review, schedule and modify call forwarding information stored and implemented by a service control-point (SCP) through a common server from any dual tone multi-frequency (DTMF) telephone and IVR system via the PSTN or any GUI and Web client via the Internet. The subscriber is able to build and edit call forwarding data, such as a scheduler and priority and rejection screening lists, by the GUI via the Internet for subsequent implementation.

Abstract: Migration of a circuit-based-switch to a packet-based-soft-switch in a SS7 telecommunications network is accomplished with no disruption to subscriber service and retains and reuses the assigned signaling point code (SPC) of the existing circuit-based-switch. The system and method inserts a new soft-switch between an SS7 signaling transfer point (STP) and the existing circuit-based-switch in a way where traffic is split incrementally off the circuit-based-switch to the soft-switch so that no administrative changes are required at either the STP or the existing circuit-based-switch. The soft-switch is gradually cutover to act as a proxy STP and tandem switch for the existing circuit-based-switch and routes all calls to and from the network on behalf of the existing switch. The system makes use of multiple internal networks of the soft-switch to accomplish the controlled routing of bi-directional traffic.

Abstract: A method and system for measuring the usage of advanced intelligent network (AIN) resources includes providing a call processing record (CPR) logic diagram for a service control point (SCP) in an AIN to follow for providing an AIN service for a call. The CPR logic diagram includes separate paths having functions to be performed by the SCP during the call. The processing times required by the SCP for performing the functions associated with the paths of the CPR logic diagram is then estimated. The estimated processing times are then associated with respective paths of the CPR logic diagram. The SCP is then monitored to determine which path the SCP follows during the call. The actual processing time expended by the SCP during the call is then determined as a function of the path followed by the SCP for the call.

Abstract: An enhancement to AIN fault handling that allows SSP triggers to access an alternative treatment application when fault handling is invoked. If an alternative treatment application is referenced in the BCM fault handling attribute, then the application is called when AIN fault handling is invoked. If the alternative treatment application is not successful in completing the service function, then one of the traditional fault handling options is applied, (i.e., routing to a specific directory number, voice announcement then terminate call, continue, or final treatment). The present invention allows a last attempt at completing the service function by the alternative treatment application after fault handling is called, but before default handling or final treatment is invoked.

Abstract: A method in a Wireless Intelligent Network (WIN) of handling subscriber services when a serving Mobile Switching Center (MSC) does not support all WIN triggers. The WIN includes a Home Location Register (HLR) having a subscriber profile that indicates the WIN triggers required to support a particular subscriber's active services. When an invoke message is sent from the MSC to the HLR, a WIN Capabilities (WINCAP) parameter is included and indicates the WIN triggers supported by the MSC. The HLR identifies a Service Control Point (SCP) for each subscriber service that requires a WIN trigger and is not supported by the MSC. The HLR then queries each identified SCP for call-treatment instructions. If an SCP determines that its service is essential, a response is returned to the HLR with an instruction to deny service to the subscriber.

Abstract: In a telecommunications network, a communication channel identifier agent (CCIA) is employed to identify communication channels. The CCIA directs the ISUP layer residing on a node to create Interface Identifiers (IntfIDs). The IntfIDs may contain an originating point code and a network identifier. The IntfIDs allow a node to use more than one originating point code to identify itself to other nodes in the telecommunications network. The IntfIDs are combined with circuit identification codes to identify communication channels between nodes in the telecommunications network.

Abstract: The preferred embodiments described herein include a method and system for billing for the use of a service control point (“SCP”). In one presently preferred embodiment, an SCP receives a query from a service switching point (“SSP”) and accesses data in a database in response to the query. The accessed data is associated with a data owner. The SCP tracks that the SSP sent the query and that the data owner's data was accessed in response to the query. After a plurality of queries have been received and tracked, the SCP creates a billing record and sends it to a billing center. Using the billing record, the billing center can charge the SSP for the use of the SCP. These preferred embodiments provide an efficient way for charging for the usage of an SCP, especially when the SSP querying the SCP is owned by a different telecommunications company.

Abstract: A privacy screening service in an Advanced Intelligent Network (AIN) includes a service node which records a caller's name when a call directed to a subscriber of the service originates at an unknown number. The service node, in turn, places a call to the subscriber and transmits the recorded name together with a signal which is recognizable by a voice mail system. Following the transmission, the service node waits for the subscriber either to accept or reject a call from the caller. When the subscriber's line is answered by a voice mail system, the voice mail system recognizes and acknowledges the signal so that the voice mail system and service node may determine that their call is between two machines and may take appropriate action. One such action is to connect the caller to the subscriber's voice mail and to restart the subscriber's outgoing voice mail greeting.

Interfaces to the first and second type links are provided in a layer, such as the message transfer part level two (MTP2) layer. If the layer is configured to a first mode, then the commnunication occurs through the interface to the first type link. If the layer is configured to the second mode, then the communication occurs through the interface to the second type link.

Abstract: A method for routing messages in a telecommunications network is disclosed.

The method also includes routing the SCCP message in response to the determined type of upper layer protocol.

Abstract: An advanced intelligent network (AIN) stores, at time of service provisioning, call processing records (CPRs) associated with select special needs services. The CPR initiates alternative processing or suppresses processing of a CPR associated with a called party to provide special services. For example, public safety and emergency readiness and response organizations are identified at time of initial service provisioning with an appropriate passive user service CPR stored in a service control point thereby invoking special call processing requirements when calling another subscriber. Thus, subscriber AIN services which might block or reroute a call placed by an emergency organization would be suppressed by operation of the CPR associated with the calling telephone line. Other special need calls might also be accommodated.

Abstract: In one embodiment, the system includes a processor (referred to herein as a tandem access controller) connected to the PSTN which would allow anyone to directly provision, that is to say set-up and make immediate changes to, the configuration of his or her phone line. In another embodiment, a tandem access controller (TAC) subsystem is connected internally to the PSTN in a local service area. The TAC provides features, selected by the subscriber, to all edge switches connected to the PSTN tandem switch. In one embodiment, the TAC is controlled by the subscriber using the web.

Abstract: A system and method for providing automatic call-back services between subscribers and designated callers. The system and method use the features of an advanced intelligent network to intercept calls to a subscriber from designated callers. The callers are instructed to hang up and wait for the return call. The system then initiates a return call originating from the subscriber's line and using the subscriber's long distance carrier. The system and method allows subscribers to identify certain callers for whom the subscriber is willing to incur long distance charges when the caller attempts to call the subscriber. Unlike traditional systems allowing a called party to reverse charges for incoming calls, the system and method of the present invention advantageously uses the subscriber's preferred long distance service provider. In this manner, the subscriber need not pay the additional surcharges normally associated with traditional “collect” calling services.

Abstract: A method and a system for reducing transmission of parameters between a-mobile switching center and a service control point in a telecommunication network such as the Wireless Intelligent Network. The mobile switching center transmits a first signaling message containing only a first set of parameters to the service control point during initial call processing. In response, the service control point transmits a second signaling message to the mobile switching center indicating to the service switching point a second set of parameters required by the service control point with respect to the first signaling message. The service switching point then transmits the second set of parameters in a third signaling message to the service control point in response to the second signaling message.

Abstract: A system and method for alerting wireless telephone users whether a call is a toll call. This invention provides communication subscribers with a notification when placing a toll call to either other wireless or landline subscribers. The notification may be a toll notification informing the subscriber that a long distance call is about to be placed. The notification means may be a pre-recorded message, tone alert, e-mail message or any other means of alerting the user. Advantageously, the caller may terminate the call upon notification that he has engaged in a toll call, prior to the call being connected to the called party. The result is that the user is fully aware and in control when placing calls that he may not recognize are toll calls, due to impacts from local number portability or roaming of the wireless user.

Abstract: A method and apparatus for establishing a connection from a calling A-subscriber to a called B-subscriber in a telecommunications TC network that offers IN (=Intelligent Network) services, in particular in a multi-operator environment with IN-supported telephone number portability, is characterized in that upon determination of the target address of the called B-subscriber, a service requested for the current call by the calling A-subscriber is simultaneously compared to a stored service profile of the called B-subscriber and in the event of a determined incompatibility, a corresponding negative release message is sent to the calling A-subscriber. This permits the calling A-subscriber, before a possibly pointless connection is made to a called B-subscriber, who does not offer the services desired by the A-subscriber at all, to not even make the connection in the first place, which would be pointless for the calling A-subscriber.

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.

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 method, in an advanced intelligent communications system, for routing a call based on the location of the calling party number where a telephone call to an abbreviated destination telephone number is received at a service switching point. The service switching point determines if the abbreviated destination number is a triggering number, and if so, notifies a service control point of receipt of the telephone call. The location of the calling party number is determined from location information related to the service switching point. The appropriate routing of the telephone call is determined based on the location of the calling party number. Call routing information regarding the telephone call is sent to the service switching point where the service switching point routes the telephone call to a destination number or a default announcement.

Abstract: The present invention allows a single trigger, such as a Termination Attempt Trigger, to invoke multiple feature service logic programs (feature SLPs) through the use of a Feature Interaction Manager service logic program (FIM-SLP) installed at a service control point (SCP). A database, accessible by the service control point, contains subscriber information such as the type of services subscribed and the order in which the services are to be invoked. The Feature Interaction Manager service logic program invokes individual feature SLPs based on the information contained in the database that specify how the feature SLPs will interact. In one embodiment, the present invention allows multiple services to be deployed within a common service control point. In a different embodiment, the Feature Interaction Manager service logic program located in a first service control point can also invoke features SLPs that are located in other service control points.

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: In accordance with the invention, at least at one exchange at least one state model or a service-specific portion of the state model, such as a call segment is formed for each service associated with the same party (A, B) of the same call, with which portion a connection to the control point of the intelligent network service is operatively associated.

Abstract: A system and method for providing call information query stores modified call information associated with a telephone number within the local databases of a service provider's local network. The modified call information enables a service provider to unilaterally alter how calls are routed and rated. The service switching points (SSPs) located within a same local network are equipped with modified intelligent network or advanced intelligent network software that enables the local SSPs to receive remote call information resulting from a remote query performed by a remote SSP. The local SSPs analyze the remote call information and generate queries to their local databases to obtain modified call information. New services requiring modified call information can then be implemented based upon the modified call information received as a result of the queries.

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.

Abstract: An intelligent network in which the service switching points (SSPs) consult a lookup table for services which require the use of a service control point (SCP), and send respective request messages containing a service type field. If such a service is one which can be handled by an SCP whose LAN (for the intercommunication of its various data processors) has become partitioned because of, say, a LAN fault, the SSP writes a first value for service type into the field, and if the service is one which must not be handled by a partitioned SCP, the SSP writes a second value. The request messages are sent via service transfer points (STPs). The network includes a transmission controller which has first and second states. Any SCP which detects that its LAN has become partitioned commands the transmission controller to enter the second state.
