Abstract

Transportation infrastructure service discovery arrangement disclosed. In the arrangement a peripheral device is attached to a transportation infrastructure control network. The client is configured to request an address from a DNS server of the host network. As a response the client receives network settings that can be used for contacting applications attached to the transportation infrastructure control network.

First claim

The invention claimed is:

1. A method for discovering applications in a transportation infrastructure control network connecting transportation infrastructure peripheral devices to an elevator or escalator arrangement, which method comprises:
connecting a transportation infrastructure peripheral device to the transportation infrastructure control network;
transmitting a DNS-query;
receiving a response to the transmitted DNS-query, wherein the response comprises an address for each of the applications in the transportation infrastructure control network, the applications include at least one of an elevator group master service, a site manager serves that runs several system level functions and services that are necessary for operations of the transportation infrastructure control network and serves for authentications and providing services for the transportation infrastructure peripheral devices;
transmitting a service query to at least one received application address;
receiving a response by the transportation infrastructure peripheral device in response to the transmitted service query, said response being a confirmation that the requested service has been performed, and
receiving a service for the transmitted service query,
wherein the response to the transmitted DNS-query further includes an address for an additional component from which the application addresses are queried.

2. The method according to claim 1 , wherein the method further comprises:
transmitting a request to a DHCP-server; and
receiving a set of network parameters as a response to the transmitted request.

3. The method according to claim 1 , wherein the method further comprises connecting to at least one application using the at least one received application address.

4. The method according to claim 1 , wherein the transmitted DNS-query comprises at least one predetermined application name.

5. The method according to claim 1 , wherein the transportation infrastructure control network is formed in an existing building network.

6. A computer program embodied on a non-transitory computer readable medium and comprising computer executable computer program code, wherein the computer program code is configured to perform the method according to claim 1 when the computer program is executed in a computing device.

7. A transportation infrastructure peripheral device comprising:
at least one processor configured to execute computer program code;
at least one memory configured to store computer program code and related data; and
at least one network connection configured to connect the transportation infrastructure peripheral device to a data communications network,
wherein the transportation infrastructure peripheral device is configured to perform the method according to claim 1 .

8. A transportation infrastructure system comprising:
at least one transportation infrastructure peripheral device according to claim 7 , wherein the peripheral device is configured to transmit queries using a transportation infrastructure control network;
at least one DNS-server for the transportation infrastructure control network, configured to receive at least one query from the peripheral device and further configured to respond to the received queries, wherein the response comprises at least an internet address for at least one application; and
at least one application connected to the transportation infrastructure control network, wherein the application is configured to receive requests from the peripheral device and as a response to perform the requested task.

9. The transportation infrastructure system according to claim 8 , wherein the transportation infrastructure system further comprises at least one DHCP-server connected to the transportation infrastructure control network,
wherein the DHCP-server is configured to receive at least one query from a peripheral device and further configured to respond to the received queries, and
wherein the response comprises at least an internet address for the peripheral device and an internet address for a DNS-server.

10. The system according to claim 8 , wherein the application is one of the following: an elevator group master service, a site manager service an authentication service, an audio stream service, a video stream service, a content management system, and a cloud service.

11. The system according to claim 8 , wherein the peripheral device is one of the following: a destination operation panel, a speaker, a display, a media screen, a device requiring authentication, an authentication device, a camera, a fingerprint scanner and a biometric scanner.

12. The method according to claim 2 , wherein the method further comprises: connecting to at least one application using the at least one received application address.

13. The method according to claim 2 , wherein the transmitted DNS-query comprises at least one predetermined application name.

14. The method according to claim 3 , wherein the transmitted DNS-query comprises at least one predetermined application name.

15. The method according to claim 2 , wherein the transmitted DNS-query comprises a special query for receiving addresses for all available applications.

16. The method according to claim 3 , wherein the transmitted DNS-query comprises a special query for receiving addresses for all available applications.

17. The method according to claim 2 , wherein the transportation infrastructure control network is formed in an existing building network.

18. The method according to claim 3 , wherein the transportation infrastructure control network is formed in an existing building network.

19. The system according to claim 1 , wherein the application is one of the following: an elevator group master service, a site manager service an authentication service, an audio stream service, a video stream service and a content management system, and wherein the peripheral device is one of the following: a destination operation panel, a speaker, a display, a media screen, a device requiring authentication, an authentication device, a camera, a fingerprint scanner and a biometric scanner.
