The sequence depends on the current traffic situations on the floors (L1, L2, L3). The traffic situation is, in turn, based on the instantaneous positions of the mobile devices. These positions are each determined in each case when a mobile device, by means of data received from a first fixed point marker, accesses a database in which the data is linked to a site of the first fixed point marker. ## Claims ### Claim 1 A method for evacuating persons from a building having a plurality of floors (L1, L2, L3) and an elevator system, wherein a plurality of fixed point markers are arranged in the building at defined sites, wherein a mobile device is carried by a person, comprising: determining instantaneous positions of mobile devices in the building, wherein an instantaneous position of a mobile device is determined when the mobile device uses data received from a first fixed point marker to access a database in which the data is linked to a site of the first fixed point marker;

an elevator control through which a drive unit can be controlled in order to move an elevator car between floors (L1, L2, L3) of the building; and a safety system with a processor and a memory, wherein the safety system is communicatively coupled to the elevator control and wherein the memory stores instructions, which when executed by the processor cause the processor to: determine instantaneous positions of mobile devices in the building, wherein an instantaneous position of a mobile device is determined when the mobile device uses data received from a first fixed point marker to access a database in which the data is linked to a site of the first fixed point marker; determine a current traffic situation for each floor (L1, L2, L3) on the basis of the instantaneous positions of the mobile devices; and determine a sequence of the floors (L1, L2, L3) to be evacuated on the basis of the current traffic situation on the floors (L1, L2, L3). ### Claim 14 (depends on 13) The system according to claim 13, in which the processor also executes instructions to control the elevator system according to the determined sequence in order to move the elevator car according to the sequence. ### Claim 15 (depends on 13) The system according to claim 13, in which the processor also executes instructions to determine available escape routes for each mobile device for which the instantaneous position has been determined to a destination on the basis of the instantaneous position of the mobile device, and identifies instantaneous positions for which the available escape routes comprise using the elevator system, wherein the identified available escape routes are available for determining the sequence of the floors (L1, L2, L3) to be evacuated. ### Claim 16 (depends on 13) The system according to claim 13, in which the processor also executes instructions to cause evacuation information to be sent to a mobile device for which the instantaneous position has been determined, wherein the evacuation information is individualized for the mobile device, and comprises instructions for a person with whom this mobile device has been associated. ### Claim 17 (depends on 13) The system according to claim 13, in which a fixed point marker is arranged in an elevator car of the elevator system. ### Claim 18 A method for evacuating persons from a building having a plurality of floors (L1, L2, L3) and an elevator system, wherein a plurality of fixed point markers are arranged in the building at defined sites, wherein a mobile device is carried by a person, comprising: determining instantaneous positions of mobile devices in the building, wherein an instantaneous position of a mobile device is determined when the mobile device uses data transmitted by a first fixed point marker and received by the mobile device and is used to access a database in which the data is linked to a site of the first fixed point marker; determining a current traffic situation for each floor (L1, L2, L3) on the basis of the instantaneous positions of the mobile devices; and determining a sequence of the floors (L1, L2, L3) to be evacuated on the basis of the current traffic situation on the floors (L1, L2, L3). ### Claim 19 A system for evacuating persons from a building equipped with an elevator system, comprising: a plurality of fixed point markers each at a defined site, wherein each fixed point marker includes data identifying the fixed point marker;
