摘要:
A technique for qualification of loops for new digital subscriber line services (DSL) involves use of an expert system, such as a neural network. A database of loop characteristic information and performance data enables the expert system to train or learn how to predict performance for future loops. In response to data characterizing a new loop to be qualified, the trained expert system predicts digital subscriber line performance for the new loop. Typically, the prediction enables classification of service capacity for the new loop into one of several classes corresponding to levels of DSL service offered through the network. The database for use by the expert system is updated as each newly qualified loop is brought into service and actual performance for that loop is known.

The invention relates to a method of intercepting calls between two or more subscribers (A, B) of a communications networks (KOM) and to an interception manager and a service control platform for supporting the implementation of the method. For each of the calls, at least one of a plurality of service control points (SCP1 to SCP3) can be triggered by a service switching point (SSP1 to SSP3). The communications traffic between service switching points (SSP1 to SSP3) of the communications network and the service control points (SCP1 to SCP3) is routed through an interception manager (LIM) which is central to all service control points. The central interception manager (LIM) is triggered for a call when one (SCP1) of the service control points (SCP1 to SCP3) is triggered for this call by one (SSP1) of the service switching points (SSP1 to SSP3). When triggered for a call, the central interception manager (LIM) monitors the communications traffic between the respective service switching point (SSP1) and the respective service control point (SCP1) for the respective call and, based on information exchanged between the service switching point (SSP1) and the respective service control point (SCP1) and on predefined filter criteria, determines whether the call should be intercepted or not.

The present invention discloses a method for reducing battery power consumed by an integrated services hub supporting a plurality of telephone lines. The status of power to the integrated services hub is monitored, and upon detecting a failure of primary power, each of the telephone lines is polled to detect an off-hook condition. The status of power to the integrated services hub is monitored while polling, and the polling is stopped upon detecting a return of primary power to the integrated services hub or upon detecting an off-hook condition in one of the telephone lines. Polling is performed by placing one of the telephone lines in a standby state and the remaining telephone lines in a disabled state and monitoring the telephone line in standby state for a predetermined amount of time to detect an off-hook condition. After the predetermined amount of time has lapsed, the monitored telephone line is changed from standby state to disabled state, and the next of the plurality of telephone lines is placed in a standby state, while any remaining telephone lines remain a disabled state. This polling sequence is repeated during active polling.

An inter-network call accounting system for use in a communication network such as the public switched telephone network in Britain allows call records to be sorted according to the network operator to be charged in respect of the calls, prior to being priced and charged. A data analyzer incorporating an expert system is provided for call records which cannot be validated. The data analyzer can apply default or amended data, or can output invalid data to a suspended process awaiting updated reference information. Unfixable data is output to a sump for management purposes. A pricing and charging engine processes data already sorted according to billable entity and incorporates further data analysis for dealing with data invalid by reason of pricing and charging related information.
摘要:
A service management system for a communications network which accepts requests for communications services from service order sources. The service management system includes an interface to the service order sources, a database, and an interface to network elements which provide the communications services. The service order sources may have differing order input formats which are converted by the system into a single internal format for processing and determining of provisioning information to be output to the network-elements. The service management system includes table-driven logic which is used to validate and process the requests to determine the provisioning information. Once the provisioning information is determined, it is queued to the appropriate network element, and an acknowledgment is sent to the originating service order source. The service management system also includes a interface to query the database and network elements to perform debugging and error correction.

An automated system coordinates, controls and polices installation of customer premise equipment (CPE) for telecommunications services and provides continuing service assurance. The system verifies equipment availability on service request, schedules a qualified technician to install the CPE, and assigns distribution equipment resources to the CPE. The system notifies the technician of the installation date. The equipment resources are auto-assigned to the CPE to facilitate installation procedures. The system also auto-detects installation of the CPE and auto-enables service when the CPE is installed. Customer record creation and maintenance is automatic, and installation or operation of unauthorized equipment is inhibited. Post-installation monitoring and automatic scheduling of repair for system or equipment faults ensures continuing service assurance. The advantage is reduced service delivery time, reduced operations costs and increased customer satisfaction.

A simulator for simulating the performance of an intelligent is described. The simulator includes. a module for simulating any IN-typical event sequences (traffic simulator) according to the rules of traffic theory, and a module for the event-oriented simulation of the service control point (SCP simulator) using process models, The simulator also includes. an arrangement for exchanging data between the modules; an arrangement entering and storing the network configuration, communication service specification, and other simulation parameters, and for transferring them to the correct modules; and an arrangement outputting and/or storing the simulated data. Modules are also provided for simulating the SS7 signaling system, taking into account the functionalities of service relay points SRP and overload protection mechanisms within the IN. The simulation modules communicate in a file mode using transfer files or are linked in an online mode by a shared organization program: the online simulator. Event calendars in which events to be processed by the simulation modules are entered in their processing order and enable the processes running parallel in a real situation to be converted to sequentially executed processes are central elements of the simulator in online mode. The IN simulator can determine the performance of an IN in a present and a future configuration, thereby locating weak points and increasing IN efficiency.

In a graphical call trace display showing progress of telephone calls in a public switched telephone network, successive events in the progress of a call are represented by respective segments of a line. Each segment is controlled in appearance (e.g. in color) to indicate the nature of the corresponding event, in accordance with information derived from signalling messages in a signalling network for controlling operation of the telephone network.
