Subscriber terminal identification

摘要

Subscriber terminal identification is disclosed. An apparatus (100) controls (154) a base station (112) to form an emulated long term evolution LTE cell (130) such that tracking area code and physical cell identity of the emulated LTE cell (130) are unused by real neighbouring LTE cells, and radio frequency power level of the emulated LTE cell (130) within the emulated LTE cell (130) is higher than the radio frequency power levels of the real neighbouring LTE cells within the emulated LTE cell (130); and controls (154) the base station (112) to receive a connection request from a subscriber terminal (140) residing in the emulated LTE cell (130), whereupon, in the ensuing exchange of messages, the base station (112) is controlled to receive an international mobile subscriber identity from the subscriber terminal (140).
