A METHOD AND A NETWORK NODE IN A COMMUNICATION NETWORK FOR CORRELATING INFORMATION OF A FIRST NETWORK DOMAIN WITH INFORMATION OF A SECOND NETWORK DOMAIN

摘要

Disclosed is a method performed by a network node (300) in a communication network for correlating information of a first network domain (310) with information of a second network domain (320), the second network domain being different from the first network domain. The method comprises receiving (102) event information of a first event that occurred in the first network domain and receiving (104) event information of a second event that occurred in the second network domain, wherein the event information of the first event and the event information of the second event each comprises a user ID, UID; a time stamp, and a geographical information. The method further comprises comparing (106) the event information of the first event with the event information of the second event in order to find a correlation between the event information of the first event and the event information of the second event, the correlation indicating a possible association between the UID of the first event and the UID of the second event.
