Abstract (en)
[origin: DE19734436A1] In a communication network (N), an information message transfer means (IMTM) handles the independent forwarding of information messages to subscriber stations (A, B). When an initial call set-up request initiated from a first subscriber station (A) fails, this is detected by a detection means (DET). The information message transfer means (IMTM) is then activated and the first subscriber station (A) records a desired information message in a memory (MEM). Then the first subscriber station (A) goes into a "hung-up" operation state and is free for carrying on with other call set-up requests. The recorded information message is then transferred to the second subscriber station (B) by the information message transfer means (IMTM) which sets up an independent call to the desired subscriber station (B). With the independent setting-up of a call, it can be made sure that the information message will eventually reach the second subscriber station (B) without assistance of the first subscriber station (A).
