摘要:
A system for service control and operations for a telecommunications network. In particular, an architecture and method for a service control and operations element system. The system communicates with a plurality of interconnected telecommunications network elements via a switching and signaling subsystem. The system provides and controls the functions of the telecommunications network, including a method of measuring delay between the time a customer dials a phone number of a called party and the time the customer hears a ringback tone indicating that the called party was alerted to the call, a method of synchronizing clocks located at individual network elements with a centralized time source, and a method of time-of-day clock surveillance.

A data storage device includes a CMIP application component which receives data on network objects using the CMIP protocol from the network manager of a main network. For each attribute of each object, a CMIP/SNMP mapper component converts the CMIP object class name, attribute name and distinguished name of the object into the corresponding SNMP attribute value and this data is stored in an MIB. An SNMP application component receives requests for information from a network manager of a local network. In order to service a valid request, the SNMP application component retrieves the required data from MIB and supplies this data to the network manager for the local network using the SNMP protocol. For changes in the values of certain attributes of certain objects, the SNMP application component issues traps to the manager of the local network.

In a traffic view server (TVS) system in which the traffic through a telecommunications network is monitored, a database system is provided to enable high processing rate for the TVS, both for inserting the data into the system and for extracting the stored data out for reporting purposes. The database system is structured in three pieces, a first one handling statistics data from records that are collected by a traffic statistics system (MTS), a second one handling enhanced call detail records (ECDR) screened from the MTS, and a last one handling common material references. The statistics data are first stored in a fast response electronic storage medium, after they have been segregated into different basic types of statistics data. The thus segregated basic types of statistics data are then combined and forwarded for long term storage in a magnetic storage medium at a brief period of time after a predetermined time interval. On the other hand, the CDR and reference data are stored directly, but at a steady rate, to respective CDR and reference storage tables.

A hierarchical network management system is described which includes concentrators (2A to 5A) on the individual levels (E1 to E3) of the hierarchy as well as adjustable interfaces in the concentrators for point-to-point and bus connections. An interface is provided for a bus connection on a master side. The interface takes delays into consideration. A transmission channel can be connected to the interface. The channel includes a forward bus and return line (a5, b5). Parallel addressable apparatus (8A, 8B, 8C) can be connected to the forward and return lines. A controllable change-over switch (A8, B8, C8), inserted in the return line (b5) of the transmission channel, is provided for each addressable apparatus (8A, 8B, 8C) of the parallel combination.
摘要:
To efficiently provide a variety of different services, e.g. voice grade telephony, packet data services, and broadband services, through an integrated network, at least some routing functions relating to all of the different types of services are controlled by data stored in a single central controller. Nodes or switching points performing the routing functions for the different types of services recognize certain call processing events as triggers. In response to a trigger, such a switching point will suspend processing of the particular call and obtain routing instructions from the central controller as to how to complete call processing.
摘要:
A distributed service management system for providing communication services comprises a plurality of individual service management systems operated by a plurality of different service providers. Each service management system includes its own local database and an Interactive Distributed Transaction Monitor (IDTM) that allows locally running applications to access the local database as well as remote databases belonging to remotely located service management systems. The interfaces serve to integrate multiple individual service management systems into a single multidatabase transaction management system. The distributed service management system can be used to provide special personal communication services involving multiple service providers, such as call forwarding to a temporarily rented mobile telephone.

A method and system is provided for use in an Advanced Intelligent Network (AIN) for automatically accessing and invoking existing switch-based services without going off-hook. To be operative, the Advanced Intelligent Network must be equipped with O-called-party-busy trigger and leg manipulation functionality such as in AIN release 1.0 architecture and have at least one service node or suitable switch in electrical communication with a plurality of central offices via a suitable signaling protocol such as Transaction Capability Application Part (TCAP) protocol. The switch or service node must be operative as the home switch or virtual Service Switching Point (SSP) for subscribers to existing switch-based services. In operation, the signaling protocol is monitored to detect predetermined triggers and line conditions associated with selected switch-based services. Upon the detection of such predetermined triggers and line conditions, a first electrical signal corresponding thereto is generated for receipt by the service node SCP. Upon receipt, normal call processing is automatically suspended and call handling is transferred to the service node whereupon a second electrical signal is generated prompting the subscriber to select the associated switch-based service. If selected, by the entry of a Dual Tone MultiFrequency (DTMF) signal or other suitable response, the switch-based service will be automatically invoked without the user going off-hook.
摘要:
Increased reliability for intelligent call processing systems is provided by collecting information from communications between the network database, the subscriber database, and the network switch. Message transfers between these network elements are monitored and correlated to identify those messages corresponding to a particular call. The messages for the call are analyzed to determine which database generated the instructions for routing the call. In particular, by comparing the routing number returned to the interexchange switch with the routing instruction information supplied by the subscriber's database, it can be determined whether the call was routed according to instructions from the subscriber's database.
摘要:
A computer monitoring system which provides for the dynamic display of calling status information on an outbound dialing system. An operator at the workstation points to icons and, using a mouse, clicks on a selected device representing physical terminals or calling equipment to see summary data related to performance and status. Modifications of the procedure occur when a key is held down while pointing at an icon. In this case, the system will transition to a more detailed display screen and show summary charts and graphs of system or operator performance at their current task.
