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: A method of use of a UMTS telecommunications network, comprising utilising UMTS signalling to indicate changes in an IP sub-network. To register a Mobile Terminal (MT) or to update its location within the network, signalling relevant to the IP domain is transmitted with UMTS signalling in an integrated approach. This reduces the number of signalling messages that are required and minimises delays.

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.

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.
