Abstract

A method of transferring the identity of subscriber A to a second centre (VMSC) serving a roaming subscriber B. A first centre (GMSC) receives a call set-up request from subscriber A and defines the identities of the subscribers and the address of the second centre (VMSC). It then sends to a service control point (SCP) an intelligent network service initiating message. The service control point (SCP) sends to the second centre (VMSC) an indication stating the identity of subscriber A and that a call is incoming to subscriber B. The second centre (VMSC) may send corresponding information to subscriber B's mobile station (MS) and receive from it a response, which it sends to the service control point (SCP). The latter analyzes the response and issues in response thereto necessary call set-up instructions to the first centre (GMSC) which sets up the call to subscriber B's mobile station (MS), provided that said response indicates that subscriber B accepts said call. Subscriber B may also reject the call or defect it to subscriber C.
