Claim:
System for monitoring an occupancy area ( 15 . 1 – 15 . 3 ), which system includes a device ( 10 ) arranged in connection with the monitored party (A–D) which includes localizing means ( 12 ), means of communication ( 13 ) for communication in a wireless data communication network ( 20 . 1 – 20 . 3 ), a processor unit (MCU) and a storage medium ( 16 ), wherein at least location information ( 23 – 25 ) defining the limit of the said occupancy area ( 15 . 1 – 15 . 3 ) is arranged, based on which the current status information of the monitored party (A–D) is adapted to be defined, terminal equipment ( 22 ) arranged in connection with the monitoring party ( 21 ), and a wireless data communication network ( 20 . 1 – 20 . 3 ) as a means of communication between the said device ( 10 ) and the terminal equipment ( 22 ), and in which system the said location information ( 23 – 25 ) defining the occupancy area ( 15 . 1 – 15 . 3 ) is arranged for definition by the device ( 10 ), whose processor unit (MCU) is adapted to define the status information of the monitored party (A–D) at each time based on the current location information defined by the localizing means ( 12 ) and on the location information ( 23 – 25 ) arranged in the storage medium ( 16 ) and defining the limit of the occupancy area ( 15 . 1 – 15 . 3 ), and wherein, according to a criterion established for the said status information, the device ( 10 ) is adapted to transmit to at least one piece of terminal equipment ( 22 ) established form information by its means of communication ( 13 ), characterized in that the said established form information is network location information defined by using one or several network elements ( 20 . 1 – 20 . 3 ) which operation of the elements ( 20 . 1 – 20 . 3 ) is based on the wireless data communication network ( 20 . 1 – 20 . 3 ) technology in which area of the network elements ( 20 . 1 – 20 . 3 ) the device ( 10 ) is located.
