    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: There is disclosed a packet switched network architecture comprising a location area connected by a radio access network to at least two core networks having the same functionality, wherein the radio access network switches packet transmissions from each terminal in the location area to one of the at least two core networks in dependence on the capacity of the respective core networks.

    Abstract: In a mobile radio network such as the Universal Mobile Telephone System, for handover or relocation of control of a mobile from a serving RNC 22 to a target RNC 24, the TRNC 24 sends a request to the SRNC 22 over the Iur link 27, and the SRNC 22 returns frame timing information. The TRNC 24 synchronizes the user plane with the SRNC for this uplink, so that both controllers are able to send the same packets in synchronizm. The core network (10) can suppress the duplicated packet.

    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).
