Method, exchange and telecommunications network for controlling the establishment of connections to a subscriber who is the destination of mass calling

摘要

Measurements are performed for detecting a mass calling to a subscriber (T) in a telecommunications network (KN), for controlling the establishment of connections to the subscriber (T) who is the destination of the mass calling. If a connection is blocked as a busy connection due to a detected mass calling, information announcing the establishment of the busy connection to the involved exchanges (B3, B, M, M2 and BM22) is added to a back-signalling message to release the connection which is busy because of the mass calling.
