Abstract
A method and network elements for obtaining a subscriber identity of a User Equipment () being served by a LTE cell () exploits a conventional handover procedure by generating a 'fake' handover request at the LTE (source) cell () designating a 3G cell () as the target. The target 3G cell is arranged to forward the subscriber identity which is included in a relocation request message received from a core network () to the LTE cell and to send a relocation failure message back to the core network.
