Abstract

A visual search and augmented reality are performed in a communication system that includes an Internet network attached to a mobile network. Data related to objects that are geographically related to at least one intermediate node is stored in at least one intermediate node in the mobile network. This involves transmitting a request for metadata from a user equipment in the mobile network towards the Internet network via the at least one intermediate node. The request comprises object recognition data related to an object geographically related to the at least one intermediate node. The request is de-tunnelled and intercepted in an intermediate node of the at least one intermediate node.

Claims

1. A method for performing visual search and augmented reality in a communication system comprising an Internet network attached to a mobile network, the method comprising:

storing in at least one intermediate node in the mobile network, data related to objects that are geographically related to the at least one intermediate node;

transmitting a request for metadata from a user equipment in the mobile network towards the Internet network via the at least one intermediate node, which request comprises object recognition data related to an object geographically related to the at least one intermediate node; and

de-tunnelling and intercepting the request in an intermediate node of the at least one intermediate node.

2. The method for performing visual search and augmented reality according to claim 1, wherein the stored data comprises object recognition data and metadata.

3. The method for performing visual search and augmented reality according to claim 2, comprising:

matching successfully, the request against a filter function in the intermediate node.

4. The method for performing visual search and augmented reality according to claim 3, comprising:

as a result of the successful matching, further matching successfully, the object recognition data in the intercepted request against object recognition data stored in the intermediate node.

5. The method for performing visual search and augmented reality according to claim 4, comprising:

as a result of the successful further matching, establishing existence of metadata corresponding to the object; and

re-tunnelling and forwarding the existing metadata from the intermediate node to the user equipment.

6. The method for performing visual search and augmented reality according to claim 1 comprising:

matching un-successfully, the request against a filter function in the intermediate node; and

as a result of the un-successful matching, re-tunnelling and forwarding the request for metadata from the intermediate node towards the Internet Network.

7. The method for performing visual search and augmented reality according to claim 3, comprising:

as a result of the successful matching further matching un-successfully, the object recognition data in the intercepted request against object recognition data stored in the intermediate node; and

as a result of the un-successful further matching, re-tunnelling and forwarding the request for metadata from the intermediate node towards the Internet Network.

8. The method for performing visual search and augmented reality according to claim 4, comprising:

as a result of the successful further matching, establish non-existence of metadata corresponding to the object; and

as a result of the established non-existence of metadata, re-tunnelling and forwarding the request for metadata from the intermediate node towards the Internet Network.

9. The method for performing visual search and augmented reality according to claim 5, wherein the metadata is personalized in the intermediate node based on characteristics of the user equipment.

10. The method for performing visual search and augmented reality according to claim 1, whereby the storing of data in the at least one intermediate node is performed according to relevance of metadata in relation to the at least one intermediate node and by transferring the data from higher levels to lower levels.

11. The method for performing visual search and augmented reality according to claim 1, whereby charging data record are generated per generated search request and forwarded to an operator.

12. A non-transitory computer-readable storage medium having stored therein a computer program loadable into a processor of a communication system, wherein the computer program comprises code adapted to perform a method for performing visual search and augmented reality in a communication system comprising an Internet network attached to a mobile network, the method comprising:

storing in at least one intermediate node in the mobile network, data related to objects that are geographically related to the at least one intermediate node;

transmitting a request for metadata from a user equipment in the mobile network towards the Internet network via the at least one intermediate node, which request comprises object recognition data related to an object geographically related to the at least one intermediate node; and

de-tunnelling and intercepting the request in an intermediate node of the at least one intermediate node.

13. A Mobile Network Operator node in a communication system, the node being configured to perform visual search and augmented reality, the node comprising:

means to receive and means to store data in the node; and

means for de-tunneling and intercepting a received request for metadata.

14. The Mobile Network Operator node according claim 13, the node further comprising:

means for matching the intercepted request against stored data;

means for extracting stored metadata from a storage in the node, which extracted metadata corresponds to requested data; and

means for re-tunnelling and forwarding the extracted metadata towards a user equipment.

15. The Mobile Network Operator node according to claim 14, the node further comprising:

means for re-tunnelling and forwarding the request towards the internet.
