Abstract

The present invention relates to a method for handling a service request within a local area network. First a service request is received from a user device. The service request comprising information regarding one or more requirements needed to perform the service. Then a download location is localized by means of a localization service within a public network to obtain computer executable information on the basis of the information in the service request. The computer executable information is then retrieved for performing the service from the download location and installed on a networked device within the local area network. Finally, a message is sent to the user device regarding the availability of the service within the local area network.

Claims

after receiving the service request, the service provisioning broker modifying the service request by adding additional information relating to capabilities of the gateway system upon which computer executable information will be installed for offering the service by the networked device to the user device;

the service provisioning broker forwarding the modified service request to a service locator system within the public network to obtain information indicative of one or more download locations of the computer executable information determined based on (i) the information regarding one or more requirements needed by the user device to perform the service and (ii) the additional information;

retrieving, by the service provisioning broker from the service locator system, the information indicative of the one or more download locations suitable for downloading the service;

selecting a download location from the one or more download locations;

retrieving, by the service provisioning broker, the computer executable information from the selected download location for performing the service and arranging installment of the computer executable information on the networked device so as to offer the service by the networked device in the local area network to the user device requesting the service; and

after the installment, sending a message to the user device regarding the availability of the service within the local area network.

2. The method of claim 1 further comprising, after receiving the service request, checking if the service is available within the local area network, wherein the, forward the modified service request, the retrieving the one or more download locations, the selecting the download location, the retrieving the computer executable information and the arranging installment of the computer executable information are executed when the service is unavailable.

3. The method of claim 2, wherein the checking comprises forwarding the service request to devices within the local area network, and waiting, for a predetermined period of time, for a response message from one of the devices confirming that the service is available, and wherein the service is considered to be unavailable if no confirmation response message has been received within the predetermined period of time.

4. The method of claim 2, wherein the local area network comprises a service registry comprising a list of services available within the local area network, and the checking comprises consulting the service registry.

5. The method of claim 1, wherein the retrieving the one or more download locations comprises:

receiving multiple locations suitable for downloading the service from the service locator system; and

selecting the download location.

6. The method of claim 5, wherein the selecting the download location is based on predetermined criteria.

7. The method of claim 6, wherein the selecting the download location comprises:

forwarding to the user device the multiple locations suitable for downloading the requested service; and

receiving a selected download location from the user device in response.

8. The method of claim 5, wherein selecting the download location comprises the gateway system selecting the download location based on gateway system preferences and knowledge of the public network.

10. The method of claim 1, further comprising:

in response to receiving the service request, sending a provisional response to the user device, wherein the provisional response comprises information regarding a time for making the service available in the local area network.

11. The method of claim 10, further comprising:

based on the provisional response, the user device extending a waiting time before the user device would terminate the service request.

12. The method of claim 1, further comprising:

in response to receiving the service request, sending a provisional response to the user device, wherein the provisional response comprises information regarding an expected time to obtain more certainty with respect to availability of the service in the local area network.

13. The method of claim 1, wherein the networked device in the local area network is a software execution device.

14. The method of claim 1, further comprising:

the user device sending the service request in response to a realization by the user device that the service is needed.

9. A non-transitory computer readable medium having instructions stored thereon that, when executed by one or more processors of a service provisioning broker on a gateway system coupling a local area network to a public network, cause the service provisioning broker to carry out operations including:

receiving a service request from a user device on the local area network requesting a service to be offered by a networked device of the gateway system in the local area network, the service request comprising information regarding one or more requirements needed by the user device to perform the service;

after receiving the service request, modifying the service request by adding additional information relating to capabilities of the gateway system upon which computer executable information will be installed for offering the service by the networked device to the user device;

forwarding the modified service request to a service locator system within the public network to obtain information indicative of one or more download locations of the computer executable information determined based on (i) the information regarding one or more requirements needed by the user device to perform the service and (ii) the additional information,

retrieving from the service locator system the information indicative of the one or more download locations suitable for downloading the service;

selecting a download location from the one or more download locations;

retrieving the computer executable information from the selected download location for performing the service and arranging installment of the computer executable information on the networked device so as to offer the service by the networked device in the local area network to the user device requesting the service; and

after the installment, sending a message to the user device regarding the availability of the service within the local area network.

15. A gateway system for handling a service request within a local area network, the gateway system configured to couple the local area network to a public network and comprising:

an interface device providing a communication interface between the local area network and the public network;

a networked device for enabling installment of computer executable information within the local area network;
