- receiving a call setup message at a telecommunications exchange associated with said called party subscriber, said call setup message originated from said calling party subscriber towards said called party subscriber;
determining that a call connection towards said called party subscriber is restricted;
determining a number of call setups previously attempted by said calling party subscriber towards said called party subscriber;
comparing said determined number of call setups with a predefined threshold value; and

Abstract
An application module associated with a terminating telecommunication exchange serving a particular called party subscriber maintains data reflecting the number of call setups attempted by a calling party subscriber toward the restricted or barred called party subscriber. In case the number of call setups attempted by the calling party subscriber within a predefined time period reaches a certain threshold level, an incoming call connection is effectuated toward the otherwise restricted called party subscriber. As a result, even if the called party subscriber has a do not disturb (DND) call barring subscriber feature activated, emergency or urgent calls repeatedly made toward the called party subscriber are allowed to be terminated thereto.

10. A system for establishing a call connection between a calling party subscriber and a called party subscriber within a telecommunications network, said system comprising:
-
a switch for receiving a plurality of call setup requests, each of said call setup request including a called party directory number (CdPn) addressed to said called party subscriber and a calling party directory number (CgPn) identifying said calling party subscriber; a register for storing said CgPn and associated with said called party subscriber, said register further comprising; a plurality of time-stamp fields for storing time for each of said call setups attempted by said calling party subscriber towards said called party subscriber; and a call counter field for indicating the number of call setups attempted by said calling party subscriber; and an application module associated with said switch for; updating said time-stamp fields and said call counter field each time a particular one of said plurality of call setup requests is received by said switch; and establishing a call connection between said calling party subscriber and said called party subscriber if said call counter for said calling party subscriber has reached a predefined threshold number imposed on said application module. - View Dependent Claims (11, 12, 13, 14, 15)
