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: Base stations, system, methods, and computer programs are disclosed to implement two successive or simultaneous ad hoc (Long-Term Evolution) LTE cells. The successive LTE cells are set up successively on a same channel number but with different Physical Cell IDs (PCID) and Tracking Area Codes (TAC). The simultaneous LTE cells are set up simultaneously on different channel numbers, and with different PCIDs and TACs. A radio connection is set up in the ad hoc LTE cell to an LTE user apparatus, and a Non-Access Stratum (NAS) timer is set simultaneously. The following is repeated until a predetermined period of time remains before an expiry of the NAS timer: commanding the LTE user apparatus to use full buffer in all uplink messages; forcing the LTE user apparatus to send uplink messages; and receiving a reply message from the LTE user apparatus.

Abstract: Method and arrangement for collecting subscriber identity is presented. A communication intelligence cell is formed for carrying out uplink and downlink communication with cellular mobile devices. The cell is connected to the identity query interface of the cellular network operator. An encrypted subscriber identity of the cellular mobile device is received from a mobile device. A radio connection to the mobile device is closed. A second registration request with a temporary identity of the cellular mobile device is received from the mobile device. An identity query with the temporary identity of the mobile device is transmitted to the identity query interface and permanent identity of the mobile device is received from the query interface.

Abstract: Subscriber terminal identification is disclosed. An apparatus controls a base station to form an emulated long term evolution LTE cell such that tracking area code and physical cell identity of the emulated LTE cell are unused by real neighbouring LTE cells, and radio frequency power level of the emulated LTE cell within the emulated LTE cell is higher than the radio frequency power levels of the real neighbouring LTE cells within the emulated LTE cell; and controls the base station to receive a connection request from a subscriber terminal residing in the emulated LTE cell, whereupon, in the ensuing exchange of messages, the base station is controlled to receive an international mobile subscriber identity from the subscriber terminal.
