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: A radio telecommunications network comprises a transmitter (2) and a receiver (4). The transmitter (2) is operative to send signals indicative of data, and the receiver (4) is operative to receive the signals (12) and decode the signals to determine the data. The receiver (4) comprises indicator means to send to the transmitter (2) an indication of whether data has been correctly determined, and the transmitter (2) is operative to retransmit at least some data not correctly determined. The receiver (4) further comprises a buffer (14) operative to store the determined data. The buffer (14) is operative to output the determined data at a predetermined rate.

Abstract: In a data packet, e.g. a PDU of the UMTS, a length indicator field (16) of variable granularity is created, depending on the exact length of the payload to be transmitted. An additional field (14) is provided, a single bit in length, to indicate the granularity of the length indicator field. This increases the resolution of the header, whilst keeping low an overhead of extra field bits. The method of the invention comprises: a. assessing (32, 34) the length of the data to determine the appropriate units, from a plurality of possible units, in which the length should be expressed; b. setting (36, 40) a granularity field to define said appropriate units in which the length of the data is to be indicated; and c. setting (38, 42) the length indicator field to indicate the data length.

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 to al least one other uplink channel for communicating user data, said 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. The network may be UMTS or UTRAN and the data channels may be DPDCHs. A RNC sends the power control preamble (PCP) length to both the base-station and mobile station this enables the base-station to allocate the new channel after the power level adjustment.

Abstract: User equipment for use in a mobile communication network has a data store 20 and a processor 2 for writing data received from a base station in the network to the store. Non-urgent data may be sent to the user equipment at times of low network activity, for example at night. Accordingly, the processor is responsive to downlink signalling during the setting up of a data transfer call to inhibit any audible alert.

Abstract: User equipment for use in a mobile communication network has a data store 20 and a processor 2 for writing data received from a base station in the network to the store. The user equipment comprises means for monitoring the condition of radio channels between it and the base station and reporting to the base station. A call is only allowed if the quality meets a predefined criterion. The channel having the highest quality may also be reported to the base station.

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 is provided of providing to a mobile user terminal (16) a set of measurement reporting criteria to be applied by the mobile user terminal) in respect of a predetermined cell (14) of a radio telecommunications network. The network comprises a plurality of cells (14) and a controller (10,20). The method comprises the controller selecting the set of criteria from stored sets of criteria, one set of which is a default set (34,34',34") for all cells under the control of the controller, and another set of which is a cell-specific set (36,36',36") of criteria.

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.
