In a method according to one intelligent network recommendation, when B subscriber has hung up the phone, a Service Switching Point (SSP) sends a message to a Service Control Point (SCP) about the hanging up. The SCP responds with a request to disconnect the B leg. A separate request increases unnecessary signalling. In another known method, after B subscriber has hung up, a timer is started and the B leg is disconnected only after a set period of time. This waiting time is annoying to A subscriber, especially when there are many calls to be made. In the method according to the invention, A subscriber can make a continuing call without waiting or without causing unnecessary signalling so that after a Service Control Function (SCF) receives information about the break off of the call, it sends a message to a Service Switching Function (SSF) containing a request to collect the dialling by A subscriber relating to a new B subscriber. The Service Switching Function (SSF) directs the telephone network to disconnect the connection to B subscriber and create a connection to a new B subscriber.

In a telecommunications network using an intelligent network (IN) architecture, detection point processing for a call switched by a service switching point (SSP) is carried out at a service control point (SCP) which is at a location remote from the SSP. A trigger table for use in detection point processing may be distributed between the SSP and SCP. Part of the trigger table may be downloaded to the SSP from the SCP when required for a particular call.

A feature checker (90) provides the ability to review communications service features for interaction problems at service creation time, or at runtime. Hence a feature can be reviewed against existing service features or against a specific other user's features. The feature checker is based on modelling communications service features as constraint satisfaction problems in which constraints (600, 605) determine preset relationships between values (610, 615) for variables (200, 215, 300, 400) of the feature. The model can then be searched for inconsistencies which indicate feature interaction. Interaction can be solved by building in an "alternative invoke" (610) for a feature which overcomes the inconsistency. This might be for instance a form of invoke which, when instantiated, actively suppresses a conflicting feature.

A method by means of which a first node in a first telecommunications network is able to establish cooperation with a functionality present in a second node in a second telecommunication network as a result of the second node initiating the establishment of a connection to the first node by using a reference, called interaction number, as a destination address, this interaction number being associated with the cooperation desired between the nodes. The reference is chosen from among predetermined destination addresses in the first node.

Eine zentrale Netzinstanz zur Verteilung von Anrufen an Server soll eine möglichst erfolgreiche Verteilung von Anrufen, d.h. eine geringe auslastungsbedingte Auslöserate durch die Server realisieren, auch wenn die zentrale Netzinstanz die Auslastung eines Servers nicht direkt registrieren kann. Um dies zu erreichen, überwacht die zentrale Netzinstanz den Grund für die Auslösung eines Anrufes durch einen Server und teilt einen Anruf sofort einem anderen Server zu, ohne daß die erfolgte Auslösung für die anrufende Partei erkennbar wird, wenn der den Anruf auslösende Server diesen wegen mangelnder Kapazität ausgelöst hat.

The invention relates to a method for controlling a call attempt by employing an intelligent network. The method comprises the steps of (a) processing the call attempt according to the originating half BCSM (O_BCSM) at a first point (SSP_A) having a service switching function (SSF), (b) resuming the processing of the call attempt according to the terminating half BCSM (T_BCSM) at a second point (SSP_B) with a service switching function (SSF), and (c) providing a service request from the processing that employs T_BCSM to a point (SCP) having a service control function (SCF). In order to be able to offer versatile IN services to the called subscriber as well, the processing of the call attempt is returned to the point employing the O_BCSM, and the processing is resumed according to the O_BCSM.
摘要:
A method and apparatus for providing a telephone operating company with the ability to rapidly deploy advanced services into a public switched telephone network includes a programmable service node interacting with a programmable switch matrix. The call processing of a call (associated with one or more ports) on the programmable switch matrix is controlled externally when particular triggering criteria is met (i.e., the call requires or desires external control). When the triggering criteria is met, the service node outputs a new call event notification message over a communications link to an external unit and receives one or more messages over the same link. Call control processing is achieved through this high-speed communications link between the programmable switch matrix and the external unit using a communications protocol defining a comprehensive set of primitives (instructions) for call manipulation and control at the programmable switch matrix which are received by the programmable service node. The one or more received messages include instruction data for instructing the programmable switch matrix to perform one or more actions associated with the service call, such as connecting a port with another port within the switch matrix. The service node processes the instruction data and instructs the switch matrix to perform the appropriate action(s).
摘要:
A basic call in a telecommunications network provides a transmission path between two users. Additional functionality is provided by a set of services, which, if a number are invoked during the same call it is important that they do not interact adversely with one another. For detecting service interactions a service abstract is produced based on a Basic Call State Model and data processing performed by the basic call state processing and by the services in respect of a data item.
摘要:
The invention provides a method of detecting service interactions in intelligent networks. According to the invention, the detection method comprises a first stage in which services are formally specified and an second stage in which the thus specified services are checked for possible interactions. The second stage may be executed automatically by computer.
