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: 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 of transmission of a data frame from a first station to a second station, in a code division multiple access (CDMA) telecommunications network. The network operates according to a hierarchical series of protocol processes including a physical layer process under the control of a radio link control (RLC) process. An indication of when a data frame is passed to the physical layer process for transmission to the second station is sent to the RLC process in the first station. Upon receipt of the indication the RLC process, a timer is started to time a predetermined period before again passing the data frame to the physical layer process for retransmission to the second station unless an acknowledgement of receipt from the second station is received.

Abstract: In the method provided, test transmissions between the mobile user terminal and base station antennas are made, and the received test transmissions processed to determine respective signal path quality for each of the base station antennas. Upon the determined signal path quality exceeding a first predetermined threshold, but being less than a second predetermined threshold higher than the first predetermined threshold, the mobile user terminal is connected to the corresponding base station antenna by control channels but not data channels so as to be time synchronised. Upon the determined signal path quality exceeding the second predetermined threshold, the mobile user terminal is connected to the corresponding base station antenna by both control channels and data channels so as to be call connected.
