Abstract

It is presented a data collector arranged to collect data regarding application usage in an end user device. The data collector is arranged to be located in a mobile communication network between the end user device and a server. The data collector comprises: a processor; and a computer program product storing instructions that, when executed by the processor, causes the data collector to: obtain data sent between the end user device and the server; match the data against a list of patterns; and when a matching pattern is found in the list of patterns, store application activity associated with the matching pattern in a database for application usage.

Claims

1. A data collector arranged to collect data regarding application usage in an end user device, the data collector comprising:

a processor; and

a computer program product storing instructions that, when executed by the processor, causes the data collector to;

obtain data sent between the end user device and a server;

match the obtained data against a list of patterns; and

when a pattern is found in the list of patterns that matches the obtained data, store application activity data associated with the matching pattern in a database for application usage.

2. The data collector according to claim 1, wherein the instructions for matching the obtained data against the list of patterns comprises instructions for matching a uniform resource identifier comprised in the obtained data against the list of patterns.

3. The data collector according to claim 1, wherein

the obtained data comprises a packet comprising a header and a data payload, and

the instructions for matching the obtained data against the list of patterns comprises instructions to match payload data from the data payload of the packet of the data with against the list of patterns.

4. The data collector according to claim 1, wherein the instructions to store comprise instructions to store a timestamp in the database.

5. The data collector according to claim 1, wherein the computer program product further comprises instructions to obtain additional data associated with the end user device;

and wherein the instructions to store comprise instructions to store the additional data.

6. The data collector according to claim 1, wherein the instructions to store refrains from storing a user identifier.

7. The data collector according to claim 1, wherein the computer program product further comprising instructions to:

reduce accuracy of any geographical location data associated with the end user device; and

wherein the instructions to store comprise instructions to store the geographical location data with reduced accuracy.

8. The data collector according to claim 1, wherein the application activity is an application activity in the list consisting of application installation, application uninstallation, application usage, application search in an application directory, and application usage duration.

9. A network node comprising a data collector according to claim 1, wherein the network node is arranged in a core network node of the mobile communication network.

10. A method for collecting data regarding application usage in an end user device, the method being performed in a data collector located between the end user device and a server, the method comprising the steps of:

obtaining data sent between the end user device and the server;

matching the data against a list of patterns; and

when a matching pattern is found in the list of patterns, storing application activity data associated with the matching pattern in a database for application usage.

11. The method according to claim 10, wherein the step of matching comprises matching a uniform resource identifier comprised in the data with the list of patterns.

12. The method according to claim 10, wherein the step of matching comprises matching payload data of the data with the list of patterns.

13. The method according to claim 10,

wherein the step of storing comprises storing a timestamp in the database.

14. The method according to claim 10, further comprising the step of:

obtaining additional data associated with the end user device;

and wherein the step of storing comprises storing the additional data.

15. The method according claim 10,

wherein the step of storing refrains from storing a user identifier.

16. The method according claim 10,

further comprising the step of:

reducing accuracy of any geographical location data associated with the end user device;

and wherein the step of storing comprises storing the geographical location data with reduced accuracy.

17. The method according to claim 10,

wherein, in the step of storing, the application activity is an application activity in the list consisting of application installation, application uninstallation, application usage, application search in an application directory, and application usage duration.

20. The method according to claim 10, wherein

at least one pattern in the list of patterns is associated with an application activity selected from a group of application activities consisting of:

application installation, application uninstallation, application usage, and application search,

the step of obtaining data sent between the end user device and the server comprises receiving a packet transmitted by either the end user device or the server, wherein the packet is destined for the server or the end user device and the packet has a header and a data payload,

the step of matching the data against the list of patterns comprises;

i) extracting payload data from the data payload of the packet and ii) determining whether a pattern in the list of patterns matches the extracted payload data,

the application activity data stored in the storing step identifies a certain application activity, and

the method further comprises transmitting the packet towards the server or the end user device.

18. A computer program product comprising a non-transitory computer readable medium storing a computer program for collecting data regarding application usage in an end user device, the computer program comprising computer program code which, when run on a data collector located between the end user device and a server, causes the data collector to:

obtain data sent between the end user device and the server;

match the data against a list of patterns; and

when a matching pattern is found in the list of patterns, store application activity associated with the matching pattern in a database for application usage.
