A method for controlling a semi-movable service means intended and configured for use in an airport infrastructure in a system comprising a client device (200,420) and a server device (300,430), wherein the client device is comprised in said semi-movable service means, wherein the airport infrastructure is a physical structure in which access and circulation are limited or restricted to certain users, further wherein the semi-movable service means is configured to provide a service including moving people and/or objects when the service means is in a stopping position; wherein the semi-movable means is a mobile means that can be stopped, in a stopping position of the means and capable of providing a main service characterising the function of the semi-movable means itself when the semi-movable means is in the stopping position, the method comprising the steps of: - obtaining, at the client device, identification information of a user from a user device; - sending a request message from the client device to the server device on the basis of the obtained identification information; - performing, at the server device, an authorisation process for the semi-movable service means on the basis of the received request message; - sending a response message from the server device to the client device on the basis of a result of the authorisation process; - performing, at the client device, a control of the semi-movable service means on the basis of the received response message, wherein the authorisation process comprises an authentication process for verifying the authenticity of the identification information; - obtaining, at the client device, information related to the semi-movable service means; - sending said information related to the semi-movable service means from the client device to the server device; - processing, at the server device, said received information related to the semi-movable service means; - sending a command message from the server device to the client device on the basis of the processing of said information related to the semi-movable service means, wherein said command message comprises notifications and/or alert enabling an administrator of a service to correctly provide the service. wherein the semi-movable means is a mobile means that can be stopped, in a stopping position of the means and capable of providing a main service characterising the function of the semi-movable means itself when the semi-movable means is in the stopping position, the method comprising the steps of: - obtaining, at the client device, identification information of a user from a user device; - sending a request message from the client device to the server device on the basis of the obtained identification information; - performing, at the server device, an authorisation process for the semi-movable service means on the basis of the received request message; - sending a response message from the server device to the client device on the basis of a result of the authorisation process; - performing, at the client device, a control of the semi-movable service means on the basis of the received response message, wherein the authorisation process comprises an authentication process for verifying the authenticity of the identification information; - obtaining, at the client device, information related to the semi-movable service means; - sending said information related to the semi-movable service means from the client device to the server device; - processing, at the server device, said received information related to the semi-movable service means; - sending a command message from the server device to the client device on the basis of the processing of said information related to the semi-movable service means, wherein said command message comprises notifications and/or alert enabling an administrator of a service to correctly provide the service. - obtaining, at the client device, identification information of a user from a user device; - sending a request message from the client device to the server device on the basis of the obtained identification information; - performing, at the server device, an authorisation process for the semi-movable service means on the basis of the received request message; - sending a response message from the server device to the client device on the basis of a result of the authorisation process; - performing, at the client device, a control of the semi-movable service means on the basis of the received response message, wherein the authorisation process comprises an authentication process for verifying the authenticity of the identification information; - obtaining, at the client device, information related to the semi-movable service means; - sending said information related to the semi-movable service means from the client device to the server device; - processing, at the server device, said received information related to the semi-movable service means; - sending a command message from the server device to the client device on the basis of the processing of said information related to the semi-movable service means, wherein said command message comprises notifications and/or alert enabling an administrator of a service to correctly provide the service.
