摘要

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.
