Abstract

A method and apparatus for performing analysis of client related data obtained from a communication network. A trend analyzer analyzes a trend of a client segment, which trend has been detected by a data stream analysis of the client related data. The trend reflects a change over time of at least one feature derived from the client related data. The trend analyzer then requests a batch based deep analysis when the trend fulfils a trigger condition, to find a cause for the trend. A result of the deep analysis is then provided to a result consumer. Thereby, the deep analysis may be performed only when a trend has been detected thus being more responsive to trends by the stream analysis and reguiring less resources, as compared to when data is always subjected to deep analysis regardless of whether a trend occurs or not.

Claims

1. A method in a data analyzing system for performing analysis of client related data obtained from a communication network, the method comprising:

analyzing a trend of a client segment detected by a data stream analysis of the client related data, said trend reflecting a change over time of at least one feature related to said client segment and derived from the client related data,

requesting a deep analysis when the trend fulfils a trigger condition, to find a cause for the trend by batch based analysis of the client related data pertaining to said client segment, and

providing a result of the requested deep analysis indicating said cause, to a result consumer.

2. The method according to claim 1, wherein a stream filter is applied to the client related data before said data stream analysis for extracting data related to a limited set of clients.

3. The method according to claim 2, wherein the stream filter is initially configured to extract data related to a default set of clients.

4. The method according to claim 2, wherein the stream filter is adjusted to refine the client segment, based on the outcome from any of the analyzing of said segment trend and the analyzing of the deep analysis, such that data related to said refined client segment is extracted by the stream filter.

5. The method according to claim 1, wherein the trigger condition dictates that the deep analysis is requested when said change over time of at least one feature exceeds a prescribed limit.

6. The method according to claim 1, wherein the at least one feature refers to any of:

amount of executed calls and sessions, time of day, week or season of executed calls and sessions, amount of failed calls and sessions, and a measured sensor parameter.

7. The method according to claim 1, wherein the client related data pertains to any of:

subscribers in the communication network, communication devices, and sensors.

8. The method according to claim 1, wherein the result consumer is any of:

a network operator, a service provider, and an application for monitoring or controlling a process or an environment.

9. A trend analyzer in a data analyzing system configured to perform analysis of client related data obtained from a communication network, the trend analyzer comprising:

a logic unit adapted to analyze a trend of a client segment detected by a data stream analysis of the client related data, said trend reflecting a change over time of at least one feature related to said client segment and derived from the client related data, and to determine if the trend fulfils a trigger condition, and

a requesting unit adapted to request a deep analysis when the trend fulfils the trigger condition, to find a cause for the trend by batch based analysis of the client related data pertaining to said client segment, such that a result of the requested deep analysis indicating said cause is provided to a result consumer.

10. The trend analyzer according to claim 9, wherein a stream filter is applied to the client related data for said data stream analysis for extracting data related to a limited set of clients, and the logic unit is further adapted to adjust the stream filter to refine the client segment, based on the outcome from the analyzing of said trend, such that data related to said refined client segment is extracted by the stream filter.

11. The trend analyzer according to claim 9, wherein the trigger condition dictates that the deep analysis is requested when said change over time of at least one feature exceeds a prescribed limit.

12. The trend analyzer according to claim 9, wherein the at least one feature refers to any of:

amount of executed calls and sessions, time of day, week or season of executed calls and sessions, amount of failed calls and sessions, and a measured sensor parameter.

13. The trend analyzer according to claim 9, wherein the logic unit is further adapted to receive a notification of the detected trend from a stream analyzer performing the stream analysis, and to analyze the trend with respect to said at least one feature according to a predefined model indicated in the notification.

14. The trend analyzer according to claim 13, holding different predefined trigger conditions and different corresponding predefined models, and wherein the logic unit is adapted to check if the trigger condition of the indicated model is fulfilled or not with respect to the one or more features of that model.

15. The trend analyzer according to claim 9, wherein the client related data pertains to any of:

subscribers in the communication network, communication devices, and sensors.
