    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).

    Abstract: In a call between mobiles 18, 19 located in the same UTRAN 24, and in which at least one mobile has an IMSI, a method of providing local switching in which the RNC 22 sends on an uplink from the first mobile 18 to the CN 10 information related to the first mobile, such as its IMSI, and stores at least a part of that information; when the RNC 22 receives the same information on a downlink from the CN 10 to the second mobile 19, it recognizes that the mobiles are within the same UTRAN 14 and performs local switching. Delay is reduced and the call can be charged at local rates. Instead of the IMSI, data frames from the first mobile 18 can be stored by the RNC 22 for comparison.

    Abstract: In the UMTS, handover of a mobile from a serving RNC 52 to a target RNC 54 is achieved by the TRNC 54 sending a handover command signal directly to the SRNC 52 through a Iur link 50. The link may be pre-existing or the TRNC may send a request and a protocol to set up such a link. The core network is no longer involved in handover, and a considerable time saving is achieved.
