Methods and Devices for Control of Explicit Call Transfer

摘要

The invention relates to a method for controlling an explicit call transfer during a call in a telecommunications network comprising a switching node and an intelligent network, the intelligent network comprising a service control entity and a service switching entity. The service switching entity detects that explicit call transfer is invoked, and then sends a report to the service control entity indicating that explicit call transfer took place for the call. The report may comprise the call transfer number and a call transfer phase indicator indicating whether the call is active or in alerting state. The service control entity receives the report and will control the call transfer depending on the report.
