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 neighboring 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 neighboring 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.

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: Methods and arrangements are disclosed for collecting subscriber identity. A cell is formed for carrying out communications with mobile devices. A channel bandwidth indication is transmitted and indicates to cellular mobile devices the formed cell utilizes bandwidth identical to the bandwidth utilized in neighboring real cells. A downlink radio channel power level on a given continuous channel subset of the indicated channel bandwidth is provided. A communication request from a cellular mobile device is received and radio resources allocated to the cellular mobile device from the given continuous channel subset of the indicated channel bandwidth. A subscriber identity of the cellular mobile device is received from the cellular mobile device.
