Abstract: The present invention provides a method involving a configurable random access channel structure. One embodiment of the method includes generating, at user equipment in a cell, a random access channel burst comprising a cyclic prefix, a preamble, and a number of repetitions of the preamble, wherein the cyclic prefix has a predetermined duration that is independent of the number of repetitions of the preamble, and wherein any user equipment in the cell generating random access channel bursts uses the number of repetitions of the preamble. This embodiment of the method also includes transmitting the random access channel burst over an air interface.

Abstract: A method is provided of transferring a call connection with a mobile terminal from a first network to a second network. The first network is capable of handling both circuit-switched and packet-switched modes of connection. The second network is capable of handling one of the packet-switched or circuit-switched modes of connection but not both. The terminal is capable of both packet-switched and circuit- switched call modes of connection. The method comprises the first network: identifying the location of the mobile terminal with respect to at least one of the networks, identifying the mobile terminal as being in a mode of connection not usable in the second network, instructing the mobile terminal to transfer the call connection to the other mode of connection, and transferring the call connection to the second network.

Abstract: A multicast status availability indication from an anchor (24) is provided to a plurality of base nodes (22) that are part of a multicast group serviced by the anchor (24). The availability status indication in one example is sent autonomously by the anchor (24) independent of any inquiry or attempted setup of a new session with that anchor by a base mode (22). The base modes (22) maintain a candidate anchor set that includes information regarding currently available anchors for establishing new sessions, for example.

Abstract: The present invention provides a method applicable to a mobile unit operating using Long Term Evolution (LTE) technology and having a single radio interface. The method controls a handover from a Voice over Internet Protocol (VoIP) call to a Circuit Switched (CS) call. The method comprises providing a CS call control message in a packet switched message, and routing the CS call control messages to a Mobile Switching Centre (MSC). Thereafter, a handover of the VoIP call to the CS call is initiated in response to receiving the call control message.

Abstract: In a 3GPP standards Release 6 UMTS system, in order to avoid searching at NodeB for a maximum E-DPCCH-associated metric at discrete possible valid index values, or over disjoint possible valid index regions, at the UE the three different sources of information, the fixed number bits that comprise the RSN, TFI and the H-bit components of the E-DPCCH bit field, are mapped so that the decimal equivalents of the possible E-DPCCH indices lie within a continuous range of values.

Abstract: A method is provided of registering a mobile terminal in an area of overlapping cell coverage by first and second networks for wireless mobile telecommunications. The networks are of different types. The method comprises: storing an identifier of the mobile terminal; storing in a controller a first record of in which cell or group of cells the mobile terminal is located in the first network and a second record of in which cell or group of cells the mobile terminal is located in the second network; and providing the mobile terminal with information of both records and said identifier.

Abstract: In a telecommunications system, such as E-UTRAN, a User Equipment 6 is connected to a base station eNB 8 by an early radio bearer, which is established using preset values stored at the UE 6 and at the eNB 8. This enables data to be transferred over the radio link prior to formal establishment of a radio bearer between the UE 6 and the eNB 8.
