Abstract: A method and a system for balancing load between at least two groups of dedicated uplink channels in a telecommunication network serving a plurality of user equipments ( 18 ), wherein scheduling requests received from the user equipments ( 18 ) and scheduling grants issued to said user equipments ( 18 ) are measured. Thereafter, a measurement report based on the measured scheduling requests and the measured scheduling grants is derived, which is forwarded to a radio network unit ( 10 ) controlling radio network resources, whereby a re-distribution of available radio resources is made between the at least two groups of dedicated uplinks channels.

Abstract: Interference and bit error rate measurements are made on the uplink and downlink to determine communications quality. Mobile station mobile assisted hand-off (MAHO) functionality is utilized to make the downlink measurements. Following filtering, the measurements are evaluated to identify potential candidates for reallocation. In one type of evaluation, when measured downlink bit error rate on a selected frequency is lower than a threshold and is worse than measured uplink bit error rate, then a better quality candidate is chosen to replace the selected frequency. In another type of evaluation, when a best available candidate has better interference than a worst quality one of the selected frequencies, that best candidate is chosen to replace the selected frequency.

Abstract: The present invention relates to an arrangement and a method to render the handover-related signalling traffic in a Code Division Multiple Access (CDMA)-based communication system more effective by reducing the amount of handover-related signalling traffic that must be sent between user equipment and the network. The arrangement comprises, i.a., a delay unit at least in the user equipment or in both user equipment and an appropriate network unit. The method comprises, i.a., the steps of releasing a communication link to the radio base station of a candidate cell while keeping information about the neighbor cells of said candidate cell for a delay period that is indicated by said delay unit. Accordingly, if a communication link shall be re-established to said candidate cell, its neighbor cells are only retrieved if said a delay period has expired.

Abstract: A telecommunications system and method is disclosed for efficient and flexible usage of bandwidth within a code division multiple access (CDMA) cell. Multiple carriers can be included within a CDMA cell, in which a different number of carriers can be allocated to downlink transmissions and uplink transmissions. In addition, a mobile station (MS) can allocate downlink bandwidth from different carriers to contribute to a Traffic channel, making it possible to form high user bit-rates, e.g., 4 Mbps. A CDMA cell can contain a Primary carrier with all channel types and at least one Secondary carrier with only dedicated channels and optionally power controlled common channels. The Primary carrier has a primary scrambling code and zero or more secondary scrambling codes associated therewith, while the Secondary carrier has one or more secondary scrambling codes associated therewith.

Abstract: Signal quality in a cell or cells of a cellular telephone system is improved by first determining a filtered transmitter power level that represents transmitted power levels in the cell or cells. The filtered transmitter power level is used to determine a new adaptive signal quality reference level. Finally, the new adaptive signal quality reference level is used to adjust the individual transmitter units in the cell or cells so that the actual received signal quality experienced by the communication links in the cell or cells substantially equals the new adaptive signal quality reference level.

Abstract: Each base station in a cellular telephone system includes a signal strength measurement device operable to tune to and make signal strength measurements on not only the frequencies allocated to other cells, but also on its own allocated frequencies. Measurements are made by the device on those of its own frequencies having idle traffic channels to obtain an indication of injected uplink interference. An interference penalty is then assessed against the measured uplink interference for those frequencies having more than a threshold number of idle traffic channels. The adjusted measurements for the frequencies allocated to the cell are then sorted in relative order of idle traffic channel (adjusted) measured uplink interference from a least (adjusted) interfered frequency to a most (adjusted) interfered frequency. An idle traffic channel is then selected for assignment at either call set-up or hand-off from the least (adjusted) interfered frequency.
