    Abstract: Delays on a common radio communications channel employed by plural mobile stations to communicate with a base station located in a corresponding geographical cell area are minimized by adapting transmission power based on traffic conditions. For lower traffic loads, a higher transmission power is permitted. For higher traffic loads, a lower power level is set. A transmit power level is determined using a desired signal ratio, such as a target CIR, a transmission path loss over the radio communications channel, and an interference value. One or more adaptive power parameters are also employed in that determination to adapt the open loop power control based on one or more current communications conditions and/or characteristics of the mobile station. For example, an adaptive power parameter may be a function of a current interference in a base station cell either alone or in combination with a current interference in one or more neighboring cells. The adaptive power parameter may also account for a type of data packet connection to be employed between a mobile station and the base station after random access, a mobile station's subscription, a current temperature of the mobile station, a current base station used by the mobile station, a current estimated path loss between the mobile station and base station, and/or other factors.

    Abstract: In a telecommunications network wherein a location area (LA1) contains GSM cells (26) having adjacent or neighboring UTMS cells (20), a dedicated procedure is employed to download information about a UTMS cell (20) to a mobile station (16). After entering the location area, the mobile (16) is notified of the presence of the UTMS cell (20). In response to the notice, the mobile (10) is operated to acquire specified information about the UTMS cell (20) from the network, such as frequency and scrambling code combinations, radio access bearer configuration, and information pertaining to intersystem cell selection.

    Abstract: A method for detecting a flag in connection with random access in a time divided mobile radio system, for instance, an FDMA/TDMA system, which includes digital traffic channels and control channels which are organized so that four traffic channels (TC) and two control channels (CC) are included in a TDMA-frame. A base station (BS) transmits continuously flags (B/I, R/N, R/F) in the time slots (1, 4) of the control channels. According to the invention, different numbers of binary values are assigned to the different states of one flag. A state (B) in a flag (B/I) which is particularly senstitive to errors in the transmission is given a greater number of binary values than the other state (I), whereby a secure detection of the flag is achieved.

    Abstract: An object of the present invention is to provide a mechanism for handling a handover in a more efficient way. The invention relates to a method in a mobility controller (180) in a radio access network for preparing a handover. The method comprises the following steps to be taken during data transmission between a mobile terminal (140) and a source base station (120), before the handover: Sending a request to a candidate base station (122), which request aims at measuring and reporting timing alignment to be used by the mobile terminal (140) when communicating with the destination base station (122) after the handover, if the candidate base station becomes the destination base station (122) after the handover; receiving a report from the destination base station (122) comprising said requested timing alignment; and when the destination base station (122) is selected among the at least one candidate base stations, sending a message to the mobile terminal (140) to use said timing alignment received from the destination base station (122) when communicating with the destination base station (122) after the handover.

    Abstract: For a radio communications system with time-divided frequencies, the synchronization between a base station and a mobile station is shifted as the mobile moves. The base station transmits symbol sequences with synchronization words to the mobile, which through this obtains a reference point in time. The mobile transmits to the base station symbol sequences with synchronization words, which in the mobile may be displaced in time relative to the reference point in time. The base station generates a reception point in time for the symbol sequences from the mobile by correlation and filtering. The reception point in time is compared with the reference point in time and upon a mutual deviation, a time deviation is generated for the base station. This time deviation is added to a previous time shift in the mobile. A new value for the time shift in the mobile is sent with an adjustment order and the mobile adjusts its transmission point in time relative to the reference point in time by means of the adjustment order. In order to increase the probability that the mobile detects the adjustment order, this order is repeated a number of times. If the reception point in time after this remains unchanged, a resynchronization is ordered, or as an alternative, a release of the connection. Disturbances to the radio connection due to deficient synchronization or frequently recurring resynchronization are reduced.
