Abstract

Systems and methods for defining and using a data collection profile in connection with a telecommunications network that includes multiple devices. Initially, a query is defined that concerns one or more aspects of the communications network. The query is then used as a basis for building a data collection profile. Next, a set of target devices is selected based upon criteria relating to the query. The data collection profile is then provided to the target devices which collect data in accordance with the data collection profile. Finally, the collected data is transmitted to a service platform for further processing.

Claims

1. A method for collecting data associated with a communications network that includes a plurality of devices, the method comprising:

receiving, at a target device, a data collection profile that defines data that is to be collected and a condition under which the data is to be collected, the target device having been selected from among the plurality of devices to receive the data collection profile based on a determination that the target device has at least one characteristic that corresponds to the data collection profile;

determining that a triggering condition defined by the data collection profile has occurred;

in response to the triggering condition and as specified by the data collection profile, collecting data at the target device; and

transmitting the data to a remote server.

2. The method as recited in claim 1, wherein the triggering condition comprises one or more events in the communications network.

3. The method as recited in claim 2, wherein the data relates to services of the communications network that are provided to a user of the target device.

4. The method as recited in claim 1, wherein the data relates to characteristics of a software stack of the target device that communicates with various network layers of the communications network.

5. The method as recited in claim 1, wherein the target device has received multiple data collection profiles, the method further comprising reconciling the execution of the multiple data collection profiles based on priorities associated therewith.

6. The method as recited in claim 1, wherein collecting the data at the target device is performed also in response to a configuration of the target device being compatible with collection of the data.

7. The method as recited in claim 6, wherein characteristics that indicate that the target device is compatible with the collection of the data include at least one of:

the ability of the device to collect metrics specified in the profile;

the ability of the device to respond to the triggers specified in the profile;

the RAM storage on the device available for metrics collection;

the persistent storage on the device available for storage of metrics packages;

the processing power of the device; and

the general ability of the device to execute the specified data collection profile.

8. The method as recited in claim 6, wherein the data collection profile defines a configuration of the target device that is compatible with the collection of the data.

9. The method as recited in claim 6, wherein, at a later time when the configuration of the target device is not compatible with the collection of the data:

the triggering condition occurs; and

the data is not collected or only a subset of the data is collected.

10. The method as recited in claim 1, further comprising purging the data collection profile from the target device upon expiration of the data collection profile.

11. The method as recited in claim 1, further comprising purging specific data collection directives within the collection profile from the target device upon expiration of the data collection directive.

12. The method as recited in claim 1, wherein specified collection profiles or data collection directives within the collection profile become effective or disabled during one or more valid times.

13. The method as recited in claim 1, wherein specified collection profiles or data collection directives with the collection profile are effective or disabled after a period of time.

14. The method as recited in claim 1, wherein the triggering condition comprises a particular time.

15. The method as recited in claim 1, further comprising:

receiving another data collection profile at the target device; and

in response to determining, by the target device, that said other data collection profile is not applicable to the target device, purging said other data collection profile.

16. The method as recited in claim 1, wherein the target device has been selected from among the plurality of the devices to receive the data collection profile by accessing a target device database to determine that the target device has at least one characteristic that corresponds to the data collection profile.

17. The method as recited in claim 1, transmitting the data to the remote server comprises selecting a time for transmission based on a status of the target device.

18. The method as recited in claim 17, wherein selecting a time for transmission is performed according to at least one of:

rules defined by the data collection profile; and

a requirement of an application of the target device or an operating system of the target device, or another requirement of the target device.

19. The method as recited in claim 18, wherein the rules are defined to minimize the impact of the data transmission on the communications network.

20. The method as recited in claim 18, wherein the rules are defined to minimize the impact to the user.

21. The method as recited in claim 18, wherein the rules define multiple transmission rules which:

are attempted sequentially until the data is transmitted; and

are ordered to first attempt transmission when the transmission would result in the least impact to the user and communication network.

22. The method as recited in claim 1, further comprising processing a collection profile at the target device to locally make one of the decisions that include:

complete adoption of the collection profile;

partial incorporation of the collection profile; and

rejection of the collection profile such that the target device is self-selected out of collection.

23. The method as recited in claim 22, further comprising the target device communicating specifics of the decision that has been made back to the remote server.

24. The method as recited in claim 1, wherein transmitting the data to the remote server is performed in response to a specific event defined in the data collection profile.

25. The method as recited in claim 1, wherein a plurality of other target devices also transmit data to the remote server.

26. The method as recited in claim 1, further comprising generating a domino trigger.

27. The method as recited in claim 1, wherein collecting the data at the target device comprises placing the data in a metrics package that is stored at the target device.

28. The method as recited in claim 27, further comprising:

storing a plurality of metrics packages at the target device; and

in preparation for storing another metrics package;

evaluating memory resources of the target device to determine whether sufficient memory is available to store the other metrics package; and

if sufficient memory is not available, performing an action with respect to previous stored metrics packages to make sufficient memory available.

31. The method as recited in claim 1, further comprising, in response to a terminating triggering condition and as specified by the data collection profile, terminating collection of the data.

32. The method as recited in claim 31, further comprising, in response to the terminating triggering condition, archiving selected data within a random access memory (RAM) buffer at the target device into a metric package.

33. The method as recited in claim 1, wherein collecting data at the target device comprises storing metrics in a circular RAM buffer.

34. The method as recited in claim 33, wherein the size of the RAM buffer is configurable by the data collection profile.

35. The method as recited in claim 33, wherein the target device includes different RAM buffers associated with different metrics.

29. The method as recited in 28, wherein the action is guided by information provided within the data collection profile.

30. The method as recited in 28, wherein the action is guided by one or more of:

data storage allocations;

the nature and priority of data in the new metrics package;

the nature and priority of data in previous stored metrics packages;

the timeliness of the data in previous stored metrics packages;

the size of the new package to be stored; and

the size of previous stored metrics packages.
