Abstract: A data transmission method utilizing time division duplex between a first and a second transceiver is provided. The first transceiver transmits a signal to the second transceiver using given transmission parameters. The second transceiver estimates a signal quality metric from the signal, the metric depicting signal quality degradation caused by interference. The second transceiver compares the estimated metric to a target metric, determines an offset value on the basis of the comparison, and transmits the offset value to the first transceiver, which adjusts transmission parameters on the basis of the offset value, and transmits a signal to the second transceiver using the adjusted transmission parameters.

Abstract: The present invention optimises and reduces the needed information exchange between network entities through the interfaces which connect them. The main property of the event based reporting method of the present invention is its flexibility because it is able to change the reporting rate depending on the value of the input parameter in each instant of time. That is, it sends more reports or less reports depending on if the parameter to be reported is changing quickly or slowly, respectively. The main idea of the present invention is that reports of a data network parameter are based on the relative change of the data network parameter value with respect to the previously reported data network parameter value.

Abstract: A traffic management method includes the steps of dividing a time slot into sub-blocks, defining the amount of available capacity for non-real time use in a time slot, defining the number of sub-blocks reserved by real time use in a time slot, defining the number of sub-blocks reserved by non-real time use in a time slot, defining the number of free sub-blocks in a time slot on the basis of sub-blocks reserved by real time use and sub-blocks reserved by non-real time use, calculating a sub-block reservation rate for a time slot and averaging a sub-block reservation rate for a time slot to get down link sub-block reservation rate.

Abstract: The objective of the present invention is to provide means for exchanging usage information in the multioperator mobile networks. Despite the high amount of different reporting alternatives of the present invention, they are not contradicting each other but are only options for different needs. Also the purpose of the present invention is to provide a fair and easy solution to monitor the usage of the shared network.

Abstract: A communication system covering an area, said system comprising a plurality of first means, each of said first means being arranged to control the allocation of channels in a part of said area, at least one of said area, at least one of said first means being arranged to send information relating to channel allocation in the part of the area associated with said at least one first means to at least one other of said first means, said at least one other of said first means being arranged to take into account said received information when controlling the allocation of channels in the part of the area associated with said at least one other first means.

Abstract: A method for use in a network covering a region, said region comprising a plurality of areas, a user being assigned to at least oen of said area and having associated therewith a plurality of candidate areas to which the user may be assigned, said method comprising the steps of receiving information identifying said plurality of candidate areas; estimating for each candidate area a parameter, said parameter assuming that said user is assigned to said candidate area; and prioritising said plurality of candidate areas which takes into account the estimated value of said parameter.
