ABSTRACT:
A method and means by which a called telecommunications device (14), connected on an established PSTN telecommunications link (18) with a wireless caller telecommunications device (12), can initiate a conference call to be set up from the wireless caller device (12) by sending a command signal to a data processing means (24) interfaced (22) with the wireless caller device (12). In response to the command signal, the data processing means (24) sends a signal set to the wireless caller device (12) via their mutual interface (22), causing the wireless caller device (12) to cause the PSTN (18) to set up the desired conference link (20) at the caller end of the established link (18). The method can be applied by a called alarm monitoring facility (14) to obtain emergency assistance for a distressed wireless caller (12) by causing a conference link (20) with a caller local PSAP (16) to be set up automatically from the wireless caller device (12). In so doing, the method promotes the acquisition of needed emergency assistance in the least attainable time while accessing the best source of relevant emergency information.
