Abstract: In a UMTS, the AICH is arranged to send, in addition to a signal acknowledging that a preamble from a mobile is at an acceptable strength, an additional signal indicating that the mobile is not currently permitted to send its message; this may apply when the BTS does not have hardware resources available. If the BTS can predict when the hardware will become available, the additional signal can include a time out (T) after which the mobile system can send its message signal.

Abstract: There is disclosed a method of transmitting data in a code division multiple access system, comprising the steps of: outputting data blocks associated with a plurality of respective users in a plurality of corresponding data streams, the data blocks of each data stream being arranged in successive time frames of a constant, predetermined length; and multiplexing the data blocks on all the data streams for each given time frame. A communications system including circuitry for utilising such a method is also disclosed.

Abstract: Power control mechanisms control signal strength in a mobile wireless communication systems which communicate, at least initially, over different channels. By measuring the Signal-to-Interference ratio in signals received by a receiving station and returning that information to the transmitting station, an indication of appropriate power levels at which to transmit subsequent signals is given.

Abstract: A time division multiple access communication system is disclosed, in which down link data are transmitted over a data channel in repeated time frames each containing a plurality of time slots. Down link set up information is transmitted over a control channel to indicate from which time slot a user terminal should extract data. Each frame on the data channel includes a user packet flag to indicate whether or not each time slot in the frame contains data. Each user terminal is responsive to the set up information and to the user packet flags to extract data from its assigned time slot in those frames which the slot is indicated to contain data.

Abstract: A telecommunications network comprising a first unit and a second unit. The second unit measures the accuracy with which it receives data and transmits a value representing that accuracy to the first unit. The first unit adjusts its maximum transmission power to the second unit dependent upon said value.

Abstract: A method of releasing a connection between a mobile user terminal 22 and a first network 9 if a report of presence has not been received from the mobile user terminal by the first network 9 for a predetermined period. The predetermined period being selected to be shorter than otherwise upon the mobile user terminal 22 being determined both as being capable of communicating also with another type of network 6 for mobile telecommunications, and being in an area covered by a network of said another type such that handover to said network 6 of said another type is possible.

Abstract: A method is provided in a network for mobile telecommunications of adjusting the transmission power of a Forward Access Channel (FACH) from a base station to a mobile user terminal. The method comprises the steps of: the base station sending a signal at a first transmission power level to the mobile user terminal, the mobile user terminal sending a report of one or more parameter values dependent upon measured signal quality upon a predetermined reporting criterion being met, and the base station adjusting its transmission power to the mobile user terminal in consequence so as to maintain the measured signal quality within acceptable limits.
