Abstract: A method and fake base station for detecting subscriber identity are disclosed. Method includes The method includes: capturing at least one wireless message containing an encrypted subscriber identity of a fifth generation mobile phone system transmitted from a mobile subscriber apparatus; transmitting a reject message of the fifth generation mobile phone system for the mobile subscriber apparatus; capturing at least one wireless message of the fourth generation mobile phone system transmitted from the mobile subscriber apparatus; detecting an unencrypted subscriber identity from the at least one captured wireless message of the fourth generation mobile phone system; and transmitting a disconnect message of the fourth generation mobile phone system for the mobile subscriber apparatus.

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.
