Abstract

A method for transmitting a call parameter, such as the identifier (A&num;) of an A subscriber, to a first switching centre (GMSC) from a second switching centre (VMSC) serving the terminal (MS) of an A subscriber, when both switching centres (GMSC, VMSC) are connected to an intelligent network service control point (SCP). The second switching centre (VMSC) receives from the A subscriber a call set-up request ( ) to set up a call through the first switching centre (GMSC). The second switching centre (VMSC) transmits to the service control point (SCP) an intelligent network service initiation message ( ) which contains the call parameter (A&num;). The service control point saves ( ) into its memory the call parameter (A&num;) to wait for a second intelligent network service initiation message ( ) associated with the same call. The second switching centre (VMSC) routes ( ) the call to the first switching centre (GMSC). The first switching centre (GMSC) transmits to the service control point (SCP) a second intelligent network service initiation request ( ).
