Abstract: In a packet switched mobile radio telecommunications system such as UMTS or GSM, on hard handover of a mobile 18 a target RNC 24 requests a direct link 36 to a serving controller 22, which sends uplink frames from the mobile 18 both to the TRNC 24 and to the core network 10; the core network 10 sends downlink frames to the TRNC 24. The TRNC decides when to complete the handover, and rebuilds fram es when necessary.

Abstract: A method of establishing transmissions to a mobile station in a cellular radio communications system is described, comprising receiving a signal originating a call at a switch and notifying a network accordingly with a paging message, and supplying the paging message to the mobile station, wherein an indication of the radio service requirement is also provided with the paging message. Subsequently, only those cells which fulfil the radio service requirement need be measured, to determine which one is to be used.

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.

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.
