Abstract

The present invention relates to a user equipment device of a UMTS (Universal Mobile Telephone System) type mobile radio telecommunications system. The user equipment device (UE) works selectively in two modes of operation, a connected mode in which resources of the system are allocated to setting up a connection with the user equipment device and an idle mode. The user equipment device is identified in idle mode by a first identity (IMSI; TMSI; PTMSI) and in connected mode by a second identity. According to the invention, the user equipment device in connected mode is capable of processing messages in which it is identified by its first identity (IMSI; TMSI; PTMSI).
