Abstract
The invention provides a modification to the operation of the intelligent network instruction set whereby on transmitting an Initiate Call Attempt message between the SCP 7 and an SSP 4 an instruction is included which forces the SSP 4 to send a response message whereby the identity assigned to the actions requested is known to the SCP 7 prior to the occurrence of a BCSM event at the SSP.

- 10. A telecommunications network including at least one service control point and a plurality of interconnected service switching points, in which said service control point is arranged in use to respond to signals received from a gateway to another network to cause a call to be set up between two or more termination points of the telecommunications network, in which the service control point is arranged in use to send a message including a first instruction to one of the service switching points to cause a connection to a first of said two or more termination points characterised in that the service control point is arranged in use to send a second instruction embedded in the message to the same service switching point, in which said second instruction is arranged to force the service switching point to respond with a message to the service control point with an identity assigned by the service switching point to the action requested in the first instruction in which the service control point is arranged in use to receive further instruction signals from the gateway prior to receipt by the service control point of an event message from the service switching point in which the service control point is arranged, in use, to use the further instruction signals to send a modifying instruction message to the service switching point.
- 19. A method of operation of a telecommunications network including at least one service control point and a plurality of interconnected service switching points, the method including the steps of said service control point responding to signals received from a gateway to another network to cause a call to be set up between two or more termination points of the telecommunications network, the service control point sending a message inducing a first instruction to one of the service switching points to cause a connection to a first of said two or more termination points characterised in that the service control point sends a second instruction embedded in the message to the same service switching point, said second instruction forcing a response from that service switching point in which an identity assigned by the service switching point to the action requested in the first instruction is passed by the service switching point to the service control point and in which on receipt of further instruction signals from the gateway prior to receipt by the service control point of an event message from the service switching point, the service control point is able to send a modifying instruction message to the service switching point.
