## Abstract

According to an aspect, there is provided a method for remote operation of a plurality of elevators, each of the plurality of elevators being coupled with a communication computer. The method comprises receiving, by a remote service system from the communication computer, a rescue request associated with an elevator; providing, by the remote service system, a verification to distinguish the elevator associated with the rescue request among the plurality of elevators; enabling, by the remote service system, a data connection with the communication computer to control the verified elevator; and performing, by the remote service system, a remote operation associated with the verified elevator via the enabled data connection.

## Claims

### Claim 1

A method for remote operation of a plurality of elevators in a centralized manner by a remote service system at a remote location, the remote service system comprising a remote manual operation panel and a remote communication computer associated with the remote manual operation panel, each of the plurality of elevators comprising an elevator controller associated with a communication computer, the method comprising:
receiving, by a remote service system from the communication computer associated with an elevator, a rescue request associated with the elevator;
providing, by the remote service system, a verification to distinguish the elevator associated with the rescue request among the plurality of elevators;
enabling, by the remote communication computer, a data connection the communication computer associated with the elevator to control the verified elevator; and
performing, via the remote manual operation panel of the remote service system, a remote manual operation associated with the verified elevator using the enabled data connection.

### Claim 2 (depends on 1)

The method of claim 1, wherein providing, by the remote service system, a verification to distinguish the elevator associated with the rescue request among the plurality of elevators comprises establishing the verification by means of a shared secret.

### Claim 3 (depends on 1)

The method of claim 1, wherein providing, by the remote service system, a verification to distinguish the elevator associated with the rescue request among the plurality of elevators comprises establishing the verification by means of a challenge-response authentication.

### Claim 4 (depends on 3)

The method of claim 3, wherein providing, by the remote service system, a verification to distinguish the elevator associated with the rescue request among the plurality of elevators, comprises:
causing generation, by the remote service system, of the challenge as a visual and/or an audible signal within the elevator; and
determining, by the remote service system, based on the visual and/or audible signal that the visual and/or audible signal originates from the elevator associated with the rescue request.

### Claim 5 (depends on 1)

The method of claim 1, wherein providing, by the remote service system, a verification to distinguish the elevator associated with the rescue request among the plurality of elevators, comprises:
obtaining at least one image comprising a visually identifiable element from an interior of at least one elevator; and
verifying the elevator associated with the rescue request based on at least the visually identifiable element from the interior of the at least one elevator.

### Claim 6 (depends on 1)

The method of claim 1, wherein the rescue request comprises an identifier identifying a physical element associated with the elevator; and
providing, by the remote service system, a verification to distinguish the elevator associated with the rescue request among the plurality of elevators, comprises checking, from a memory, that the identifier is associated with the elevator subject to the rescue request.

### Claim 7 (depends on 1)

The method of claim 1, wherein the remote manual operation comprises bypassing of a safety contact.

### Claim 8 (depends on 1)

The method of claim 1, wherein the remote manual operation comprises bypassing of a safety function.

### Claim 9 (depends on 1)

The method of claim 1, wherein the remote manual operation comprises opening of at least one hoisting machinery brake.

### Claim 10 (depends on 1)

The method of claim 1, wherein the remote manual operation comprises activating of a rescue drive unit associated with the elevator.

### Claim 11 (depends on 1)

The method of claim 1, wherein the remote communication computer comprises a safety layer, and a rescue apparatus associated with the elevator subject to the remote manual operation is associated with the safety layer to establish a black channel.

### Claim 12

A remote service system for performing remote operation of a plurality of elevators in a centralized manner by a remote service system at a remote location, each of the plurality of elevators being associated with a communication computer, the remote service system comprising:
a remote manual operation panel;
a remote communication computer associated with the remote manual operation panel;
means for receiving from the communication computer associated with an elevator, a rescue request associated with the elevator;
means for providing a verification to distinguish the elevator associated with the rescue request among the plurality of elevators;
means for enabling a data connection by the remote communication computer with the communication computer associated with the elevator to control the verified elevator; and
wherein a remote manual operation associated with the verified elevator is configured to be performed via the remote manual operation panel using the enabled data connection.

### Claim 13 (depends on 12)

A remote service system of claim 12,
wherein the means are configured to perform a method wherein providing, by the remote service system, a verification to distinguish the elevator associated with the rescue request among the plurality of elevators comprises establishing the verification by means of a shared secret.

### Claim 14 (depends on 12)

An elevator system comprising:
a remote operation system of claim 12; and
a plurality of elevators comprising an elevator controller associated with a communication computer.

### Claim 15 (depends on 1)

A computer program comprising a computer program code which, when executed by at least one processor, causes the at least one processor to perform the method of claim 1.
