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.

Abstract: According to the present invention there is further provided radio resource allocation apparatus for allocating radio resources for transmission of signals along a plurality of channels to and from a node, the node comprising a transmitter/receiver for transmitting and receiving signals to and from the node and a channel selection device for selecting the channels along which different signal transmissions are to be routed, and a channel allocation device for controlling the allocation of channels by the channel selection device, the channel selection device comprising first means responsive to incoming signal transmissions passing through the node to produce a data rate signal, a bit energy to noise power ratio signal and a classification signal, second means responsive to the output of the first means to generate a maximum load parameter signal and third means responsive to an output from the channel selection device providing channel status indications and to the output of the first and second means to process the received signals in accordance with a predetermined algorithm and to feed the channel selection device with channel selection signals accordingly, wherein the algorithm of the third means includes resolving the capacity equation alpha current - alpha new ≤ alpha max = 100% - eta , where alpha current is the current load of node as given by the sum of the resource consumption of all services that are served by the node, alpha new is the additional load capacity required of the node, alpha max is the maximum load which the node is capable of and eta is a reserve safety factor, whereby if the capacity boundary of the equation is exceeded, the generation of said channel selection signals is inhibited and a resource consumption negotiation takes place following which the capacity equation is again resolved, when the boundaries imposed by the capacity equation are not exceeded, the channel selection signals are transmitted to the channel selection device.

Abstract: The method involves providing a network node (14) of a data frame from a mobile user terminal (20). For each cell (18,22) delay due to transfer of representation of the received data frame across interfaces between the nodes along a transfer path to node (14) is estimated by determining contribution to the delay caused by each interface along transfer path. Cells (18, 22) are selected dependent upon the associated delays. An independent claim is also included for a network for mobile telecommunication.

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: A telecommunications network comprises a base station and a mobile station in use in call connection on at least one uplink channel for communicating user data. The base station is operative such that on receipt of a command to transfer to and/or add at least one other uplink channel for communicating user data, the at least one other uplink channel is allocated to the call connection after a predetermined period during which power level adjustment is undertaken to compensate for mobile station movement.

Abstract: Battery operated user equipment is disclosed for use in a radio telecommunications network, including means for monitoring the state of charge of the battery and means for communicating state of charge data to a base station during call set up. The battery data can be used to inform a caller that, for example, a called user's apparatus has reduced or limited battery capacity and thus that the expected duration of a call is limited.

Abstract: The invention relates to communication systems in which end-user devices contend for access to shared resources of a channel in the communica tionsystem. End-user devices sending data in packets ove r the communication channel piggyback requests for changes in allocated resources for transmission of an other packet. A system controller changes the resource allocated to individual end -user devices depending upon the piggyback requests, in order to optimise the thro ughput of the channel. A packet switched network may thus act like a circuit switch ed network if required.
