A method and network elements for obtaining a subscriber identity of a User Equipment (105) being served by a LTE cell (104) exploits a conventional handover procedure by generating a “fake” handover request at the LTE (source) cell (104) designating a 3G cell (102) 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 (107) to the LTE cell and to send a relocation failure message back to the core network. |
