Abstract
Network node and base station and methods therein for deriving a permanent identifier, such as an IMSI, for a UE in a cellular communication system of LTE type. The solution involves the use of a request for an inter-RAT handover, where the request comprises a temporary identifier of a process associated with the UE of which a permanent identifier is to be derived. The access to a permanent UE identifier is enabled in a radio access network where such an identifier is not readily available. The solution does not require any changes to procedures or nodes in the core network.
