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 method for providing the names of the city and state of a calling party to a called party when the calling party's name is unavailable. The method utilizes the calling party's telephone number to determine the names of the city and state from which the calling party is calling. The method incorporates a database that contains combinations of telephone numbers and the names of the cities and states that correspond to the various combinations of numbers. In response to an indication that the name of the calling party is unavailable, the method accesses the databases and searches for the matching telephone number and corresponding city and state names. If the names are found, they are delivered to the calling party.

Abstract: A system and method for effectuating selective triggerless local number portability (TLNP) processing in a telecommunications network having a cellular network portion and a wireline network portion. When an IAM message is received at a signaling node from an MSC on a TLNP-enabled link set, a determination is made at an STP associated therewith whether the NPA-NXX of the received dialed number is marked as portable. If not, the TLNP processing is discontinued and the message as originally received is forwarded to the wireline network portion for further processing. Otherwise, another determination is made if the dialed number is a ported number. If it is determined that the dialed number is not a ported number, the IAM message is marked as dipped and forwarded to the wireline network portion based on the Destination Point Code (DPC) associated with the message.

Abstract: A method and system for generating customer reports based on station message detail recording (SMDR) data includes a service control point (SCP) in a public switched telecommunications network (PSTN). The service control point samples calling data from multiple service switching points for calls originating from a private customer network, including centrex and PBX systems. The service control point interfaces with a front end processor and transmits the calling data. The front end processor formats the calling data into SMDR data, which is transmitted to a host central processing unit. The host generates reports regarding the SMDR calling data, the reports being accessible by a customer via a connection to a private customer network.

Abstract: A generic access service is provided in a telephone system to enable users to get dialup access to different network access services. User profile data showing which network access services a user subscribes to is held on a database accessible to the service control subsystem of the telephone system. Upon detection of a particular phone number assigned to the generic access service an authentication procedure is initiated in the service control subsystem to identify the user. Once identified, the service control subsystem uses the user profile data to determine what access services are available to that user. Thereafter, a particular access service is selected and the number of a corresponding network access server derived.

Abstract: A party is identified with a network independent address. That address is linked to a plurality of network specific addresses. In the context of originating a communication toward that party, the network independent address is used as the dialed address. A context for the origination, which identifies the type of communication being originated (for example, voice call, data call, e-mail, and the like) and/or the network over which the originated communication is to occur, is included with the network independent address in the origination. The network independent address is used to identify the plurality of associated network specific addresses, and the context is used to select a certain one of those network specific addresses. The selected network specific address is then used to route the origination to the party. Completion of the origination using the selected network address may be controlled by either the network or terminal.

Abstract: Notification of 911 telephone calls is provided to a telephone numbers listed on a pre-provided list of the telephone numbers without intrusion on the existing 911 infrastructure using the out-of-band SS7 signaling infrastructure. A link monitoring system (LMS) monitors SS7 messages to determine whether a 911 telephone call has been made. When the LMS determines that a 911 telephone call has been made, it sends a message containing calling party number information to a notification device. Using the telephone numbers provided on the notification list, the notification device notifies others that the 911 telephone call has been made.

Abstract: Services controlling the same call state model are independent of each other and do not necessarily have any knowledge of each other. To make the facilities of these parallel controlling services interoperable, at least one parameter is defined, whose value indicates whether a controlling service may be initiated to control a control record, if a controlling service has already been initiated. When detecting (301) a situation triggering the initiation of a second controlling service in the control record controlling call set-up, the initiation of the second controlling service is continued (315), if the parameter allows the initiation of the controlling service.

Abstract: When telephone calls are placed by dialing a special number such as an “800” number, the dialed number is converted to a specially configured translation number that includes a destination output set of digits which are preferably the last four digits of the dialed number. This translation number is transported over the network from an originating switch to a terminating switch which then outputs the output set to the destination. Advantageously, the terminating switch also replaces the prefix portion of the translation number with an output prefix consisting of at least the NXX portion of the dialed number and outputs this prefix along with the output set to the destination for use in call tracking.

Abstract: A finite state machine that implements the ETSI Intelligent Network Capability Set 1 for INAP protocol using a first finite state machine connected to a second finite state machine. To accomplish this implementation, the first finite state machine receives inputs and makes initial state transition choices. Once the first finite state machine has made an initial choice, the second finite state machine checks to see if the first finite state machine has transitioned to the appropriate state and, if it has not, give feedback to the finite state machine to the appropriate state. Once the appropriate state is reached, the outputs of the first finite state machine are valid and available. The finite state machines may be realized as physical logical devices or virtually using VFSM technology.

Abstract: The functions of a Signaling System 7 (SS7) network node are divided among multiple nodes of an Internet Protocol (IP) network. An “A” node includes an SS7 application component, and a “P” node includes an SS7 transport component connected to the SS7 network. Each node also includes an IP transport component and an adapter for translating messages between IP and SS7 protocols. The A nodes and P nodes inter-operate via the IP network in a manner invisible to the SS7 network and the SS7 application component. Each adapter requests a connection to a counterpart adapter from a connectivity manager for each transaction. The connectivity manager, which may be centralized or distributed in the IP network, allocates adapters to transactions and informs requesting adapters of the allocations. For load sharing, the connectivity manager weights the adapters by their transaction processing capacities and allocates adapters in proportion to their respective weights.

Abstract: A work-at-home telecommunication service is provided in response to receiving, from a calling party, a service-specific vertical feature code and a dialed number to initiate a call. The call is suspended and a query is sent to a service control point after receiving the vertical feature code and the dialed number. The query includes the dialed number and a calling party identification number. A response to the query is formed using the service control point by translating the dialed number to a called party identification number, and by modifying the calling party identification number to an identification number of a group associated with the calling party. The response includes the called party identification number, the calling party identification number, and a carrier identification code which identifies a telecommunication carrier for the group associated with the calling party. The call is routed to the called party using the telecommunication carrier identified by the carrier identification code.

Abstract: A telephony call center has agent workstations having telephones connected to station-side ports of a telephone switching apparatus adapted to receive and switch conventional telephone calls to the telephones, and also computer platforms connected on a local area network (LAN). A processor also connected on the LAN has a wide area network (WAN) port and is adapted to receive and distribute computer-simulated telephone calls from the WAN to computer platforms at the agent stations. At individual agent stations the telephone and computer platform is connected by a Telephone Application Programming Interface (TAPI)-compliant bridge. Status of calls of both types at agent workstations is communicated to a network-level router by the processor having a WAN connection, which may also receive computer-simulated calls. The router may then make routing decisions based on agent status relative to both kinds of calls.

Abstract: A telephone networking system includes a database having executable programs which are equivalent to customer record programs used by a SCP. A switching device retrieves one of the executable programs from the database in response to data received by an input device, such as a telephone. The executable program is transmitted across the network to be executed by an edge device having the capability to store information and perform logical operations. For an 800/888 telephone call, the executable program instructs the edge device to request and gather additional information. The additional information is then used by the executable program to generate the POTS number which is transmitted to the switching device to complete the call.

Abstract: The invention concerns interworking between distributed services in a telecommunications network, especially in an intelligent network. The invention is based on the idea that at least one new Interworking Point is introduced to the call handling model and with the aid of this Interworking Point the interworking between the distributed services is implemented. The Interworking Point can be defined as either a point where instructions received from one service program are reported to interested service programs or as a point where a service to be carried out by the responsible service program is requested by some other service program. The interworking points are armed by the service programs, and the service programs which armed the interworking point are informed of the encounter with an interworking point.

Abstract: A “TC Correlate” mechanism correlates the outgoing TC-dialogue of an originating signaling point (SP) with the outgoing TC-dialogue at an intermediate SP. It allows an intermediate SP to terminate its TC-dialogue (signaling transaction) after it is no longer needed from a functional standpoint, while preserving end-to-end TCAP connectivity. It also allows an intermediate signaling point (e.g., switch or database) to forward a query to a second signaling point (e.g., second switch or database), while otherwise staying out of the TC-dialogue. In both instances, greater efficiency and better use of network resources can be achieved.

Abstract: There is provided an INAP processing method for communication between an SSP and TCAP. When an INAP message is sent from the INAP of the SSP to the TCAP, a TC component to be transmitted is generated, an invoke ID and dialogue ID are allocated to the generated TC component, a TC primitive corresponding to the state of an allocated dialogue is created and encoded, to be sent to the TCAP through the TCAP interface block. In case where the INAP of an SSP receives an INAP message from the TCAP, the received INAP message is decoded based on the type thereof and a corresponding SCP relationship object is found using the dialogue ID included in the decoded INAP message. When the TC component and TC primitive are contained in the decoded message, the TC primitive is executed first and then the TC component is processed. When a corresponding call has been processed, the found SCP relationship object is deleted, finishing the dialogue with the SCP.

A distribution network node (16) is used to receive and distribute the service logic program (15) and service management program (21) to a service logic execution environment (20, 92) residing in a telecommunications network node (30, 32, 34, 36, 50) for executing the service logic program (15), and to a management logic execution environment (22, 86, 94, 102) for executing the service management program (21).

Abstract: A user profile for use, for example in a personal numbering service, has an associated confidence value for each of the destination terminal numbers in the profile, a confidence value representing the confidence of a call being successfully answered at the associated network terminal. When a service using the profile needs to route a call for a user, the corresponding profile is accessed and the call is routed to the destination terminal number having the highest confidence value. The profile is managed to modify the confidence values depending upon the outcome of the call, and also upon registration of a personal number user at a network terminal. The confidence values are probabilities and when one confidence value is increased because of a successful outcome, the other values are adjusted. The confidence values can be a function of time to represent lessening confidence that a user is still at the network terminal of his last registration.

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.
