Abstract: Method and arrangement for detecting subscriber identity. The method includes: capturing in a fake base station at least one wireless message transmitted from a mobile subscriber apparatus interoperable with a mobile phone system; detecting an encrypted subscriber identity from the at least one captured wireless message; and retrieving an unencrypted subscriber identity from an entity inside an infrastructure of the mobile phone system based on the encrypted subscriber identity.

Abstract: 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.

Abstract: This document discloses a solution for outputting a message sequence chart in a computer apparatus. Messages transferred in a communication network are acquired, wherein the messages are logically divided into control plane messages and data plane messages and each message is associated with its transmission direction. Display of the control plane messages is caused on a display screen in the message sequence chart and in a form where each control plane message is displayed together with a unidirectional indicator indicating the transmission direction of the control plane message. Display of the data plane messages is caused in the message sequence chart in a compressed form with a single multidirectional indicator representing a plurality of data plane messages and indicating the transmission directions of the plurality of data plane messages.

Abstract: Processing of call data records is disclosed. Data packets captured from a monitored telecommunications network are obtained, decoded, and sessions are identified. The decoded data packets and the identified sessions are filtered with a dynamic filter determining adjustable conditions for the protocol attributes and the session attributes such that the decoded data packets and the identified sessions fulfilling the adjustable conditions are kept in order to get attribute-filtered decoded data packets and attribute-filtered identified sessions. Dynamic call data records are generated such that their structure and contents are determined dynamically on the basis of the attribute-filtered decoded data packets and the attribute-filtered identified sessions. The dynamic call data records are stored.
