AN IMPLEMENTATION OF CALL DROP-BACK IN A TELECOMMUNICATION NETWORK

摘要

The present invention proposes a method for performing a call drop-back in a telecommunication system, said telecommunication system comprising at least one exchange (MSC) for switching calls between at least two subscribers (A, C) or between one of said subscribers and a message server (VMS/SN), wherein sa id message server (VMS/SN) is adapted to maintain a record of a plurality of previous messages intended for a called subscriber (A) and which previous messages were recorded to the message server record from a respective callin g subscriber (C), wherein said method comprises the steps of: invoking (S6) a callback call from said called subscriber (A) to said calling subscriber (C) based on the information recorded in said message server record via at least one of said at least one exchange (MSC), and upon invoking said callback cal l, setting the system into a state enabling said called subscriber (A) to be connected back to said message server (VMS/SN) after the termination of said invoked callback call. Also, a corresponding control device as well as a network element comprising the same are proposed.
