1. A system (10) for transport of a user (B) to a destination with an elevator (L), wherein the elevator (L) comprises a control (14), wherein the system (10) comprises:
a first communication unit (KE1) configured to be carried by the user (B);
at least one second communication unit (KE2) configured to be installed in a stationary manner; and
at least one third communication unit (KE3) configured to be installed at and/or in an elevator car (LK) such that the installed third communication unit (KE3) moves together with the elevator car (LK);
wherein the first communication unit (KE1) is configured to communicate with the at least one second communication unit (KE2) in order to submit a readiness request message to the control (14) of the elevator (L) from the first communication unit (KE1) via the at least one second communication unit (KE2) and/or to communicate with the at least one second communication unit (KE2) in order to initiate a submission of a readiness request message to the control (14) of the elevator (L), to make the elevator (L) ready for the transport of the user (B);
wherein the first communication unit (KE1) is configured to communicate with the at least one second communication unit (KE2) and/or with the at least one third communication unit (KE3) in order to submit a destination message about the destination of the user (B) from the first communication unit (KE1) to the control (14) of the elevator (L) and/or to communicate with individual ones of the at least one second communication unit (KE2) or the at least one third communication unit (KE3) in order to initiate a submission of a destination message about the destination of the user (B) to the control (14) of the elevator (L) for the transport of the user (B) to the destination by means of the elevator (L);
wherein the first communication unit (KE1), the at least one second communication unit (KE2), and the at least one third communication unit (KE3) are configured to communicate using a Bluetooth Low Energy (BLE) standard in which one of the communication units operating as Peripheral (P) transmits a BLE-Advertisement and another one of the communication units acting as Central (C) scans for emitted BLE-advertisements; and
wherein the first communication unit (KE1) and the at least one second communication unit (KE2) are configured to operate as peripheral (P) and as central (C) concurrently or quasi-concurrently.
