ARRANGEMENT, COMPUTER PROGRAM CODE AND METHOD FOR CALL DATA RECORD PROCESSING

摘要

Call data record CDR processing is disclosed: obtaining a plurality of control plane call and session records produced by analysing communication in a monitored telecommunications network; aggregating control plane call data records from control plane call and session records on the basis of a subscriber identifier, each control plane call data record comprising a subscriber identifier as a key and further comprising one or more protocol addresses; creating a control plane data structure comprising subscriber identifier-protocol address-pairs gathered from the control plane call data records; obtaining a plurality of user plane call and session records produced by analysing communication in the monitored telecommunications network; and aggregating the user plane call and session records on the basis of the control plane data structure.

1. An arrangement comprising:
one or more processors; and one or more memories including computer program code, the one or more memories and the computer program code configured to, with the one or more processors, cause the arrangement at least to: obtain a plurality of call and session records CP-XDR of a control plane produced by analysing communication in a monitored telecommunications network; aggregate call data records CP-CDR of the control plane from call and session records CP-XDR of the control plane on the basis of a subscriber identifier, each call data record CP-CDR of the control plane comprising a subscriber identifier as a key and further comprising one or more protocol addresses of a mobile subscriber identified by the subscriber identifier; create a control plane data structure comprising subscriber identifier-protocol address-pairs gathered from the call data records CP-CDR of the control plane; obtain a plurality of call and session records UP-XDR of a user plane produced by analysing communication in the monitored telecommunications network; and aggregate the call and session records UP-XDR of the user plane on the basis of the control plane data structure such that call and session records UP-XDR of the user plane including the same protocol address are aggregated together.
