Abstract: In the UMTS, semi-static uplink and downlink connection parameters relating to the frequently-used services of voice, fax and web browsing are intermittently broadcast to mobile user equipment (20) which stores the parameters. When a mobile requests(30) one of those services, the relevant dynamic parameters are sent (32) over the radio interface and the mobile is asked whether it has in its store the relevant parameters for the requested service; if so (34), the call is set up; if not (36), the semi-static parameters relevant to the requested service are sent (38) to the user equipment. Considerable saving of radio resource results.

Abstract: There is disclosed a technique for link adaptation, suitable for a packet switched mobile communication system, in which a command or request to change the mode of a codec in a transmitter is sent only responsive to a change in the condition of a received signal.

Abstract: A method is provided for operating a multi-bandwidth OFDMA system that can achieve an enhanced bandwidth efficiency due to windowing without significantly impacting the underlying physical design of the receive filters. The method comprises establishing a bandwidth over which the radio resources transmit signals, the bandwidth being comprised of an edge-band and a center-band. Narrow band radio resources are assigned to a portion of the bandwidth that is at least partially within the edge-band.

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: The present invention provides a method of wireless communication. The method includes determining whether a packet includes a voice payload or control information based on at least one property of the packet. The voice payload packet is a RTP (Real Time Protocol) packet; the control information packet is a RTCP (Real Time Control Protocol) packet. The property can be the packet size, the arrival frequency of the packets or the UDP port number.

Abstract: A communication system includes a decentralized, flat architecture where a plurality of base nodes each include controller capabilities so that a centralized base node such as a radio network controller is not required. At least one of the base nodes acts as an anchor node. The anchor node associates a time stamp with at least one packet and provides that to the plurality of base nodes. In one example, a multicast approach is used by a router device for distributing the packet and the associated time stamp to the plurality of base nodes. Each base node controls a timing of a transmission of the at least one packet over a wireless interface responsive to the associated time stamp.

Abstract: An example of the present invention is a method of transmitting encrypted user data to a mobile terminal in a wireless telecommunications network. The method comprises sending to the mobile terminal a data packet. The data packet comprises both an identifier of encryption information to be used in recovering encrypted user data, and user data encrypted using the encryption information.
