Abstract: A communication system covering an area, including a plurality of first units. Each of the first units being configured to control the allocation of channels in a part of the area. At least one of the first units being configured to send information relating to channel allocation in the part of the area associated with the at least one first unit to at least one other of the first units. The at least one other of the first means units being configured to take into account the received information when controlling the allocation of channels in the part of the area associated with the at least one other first units.

Abstract: A communication system, said system arranged to provide communication coverage over an area, said system comprising a plurality of first means, each of said first means controlling at least one parameter and/or configuration setting with respect to an area smaller than said coverage area and second means for receiving information from a plurality of said plurality of first means and for controlling at least one parameter and/or configuration setting with respect to the area associated with at least one of said plurality of said plurality of first means.

Abstract: A method and system for mobile communication, in which method a channel is allocated for a connection having a certain quality of service between a mobile station and a base station in a network whose time-slots are synchronized with each other. The system collects interference information (202 to 204) from connections already in use, information on the traffic load of the network (205), defines a level value (206) for information to be communicated, forms a parameter value (201) for the channel of the cell and allocates the channel (200, 201).

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.

Abstract: The invention relates to a method for processing a traffic channel request in a cellular radio system. To ensure that the allocation of a new traffic channel would not disturb adjacent cells, the method comprises the steps of: calculating the number of traffic channels in use in a radio cell; measuring the quality of ongoing connections of adjacent cells using at least to some extent the same frequency channels as said radio cell; and preventing the traffic channel from being allocated to a mobile station from said radio cell if the number of traffic channels in use exceeds a predetermined threshold value and if in any of said adjacent cells the mean value of quality for ongoing connections is lower than a predetermined minimum quality value.

Abstract: The invention relates to a handover method, mobile system and apparatus deciding on the handover of the mobile system triggering an accelerated handover algorithm when the signal level and/or quality between the mobile station and a serving base transceiver station quickly drops. The method measures the level and/or quality of the signal between the base transceiver station and the mobile station, sets a predefined signal change as the trigger value, calculates the change in the signal level and/or quality, and if the change is at least equal to the trigger value, executes the first handover algorithm.

Abstract: A cellular radio network and a method for increasing traffic carrying capacity in a cellular network in which the operating frequency spectrum of the cellular network has been divided so that typically both regular frequencies and super-reuse frequencies are employed in each cell. The regular frequencies use a conventional frequency reuse pattern to provide seamless overall coverage (overlay). A very tight frequency reuse pattern is used for the super-reuse frequencies to provide additional capacity (underlay). The cellular network controls the division of traffic into regular and super-reuse frequencies by radio resource allocation at the call set-up phase and later on during the call by handover procedure. The cellular network continuously monitors the downlink co-channel interference of each super-reuse frequency in the cell separately for each ongoing call.

Abstract: In a hierarchical micro/macro-cell network, a mobile station will be handed over from a microcell to a macrocell if a number of microcells recognize the mobile station as fast, so that the fast moving mobile stations do not cause a considerable number of handovers between microcells, which make the call control difficult. However, in order to avoid unnecessary switches up to macrocells, a mobile station and the call are handed over to a macrocell only when the mobile station is recognized as fast in a sufficient number of microcells.
