#CMT# #/CMT# The system has a subscriber station of a mobile telephone network (MTN) to provide alarm signals, and an address allocation memory, in which individual or group addresses (RIC1) of pager mobile telephone-subscriber numbers (MN1, MN2) assigned to a substation (US) e.g. control room, are assigned. A control unit (SG) causes a transmission of class-zero-messages (AN1(C0), AN2(C0)) with the signals to mobile radio subscriber numbers in the memory via the subscriber station according to number of addresses in a post office standard advisory group (POCSAG)-coded alarm signal. #CMT#USE : #/CMT# Radio alarming system for use during a rescue operation by a task force e.g. fire-brigade of a fire station, or an emergency service. #CMT#ADVANTAGE : #/CMT# The control unit causes the transmission of the class-zero-messages with the alarm signals to the mobile radio subscriber numbers assigned in the memory through the subscriber station in the substation according to the number of addresses in the POCSAG-coded alarm signal, thus operating the alarming system in an improved manner, while avoiding an interference intervention with the POCSAG-alarm signal in the system. The system thus enables transmission of alarms to the task force in a flexible and enhanced manner without intervention in the alarming operation in a central station and/or additional work load of a control station personnel. The system eliminates the need for contracts with mobile telephone network operators, and enables transmission of the alarms over different sub-networks of the different network operators. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of a radio alarming system. MTN : Mobile telephone network SG : Control unit US : Substation ZS : Central station AN1(C0), AN2(C0) : Class-zero-messages MN1, MN1 : Pager mobile telephone-subscriber numbers RIC1 : Individual or group addresses. |
