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: The invention concerns a method for synchronising clocks of base transceiver stations in a telecommunications system and a mobile communications system. According to the invention, in either some or in all base station sites of the telecommunications network a location measurement unit is installed, which receives an accurate clock including an extra-system signal. The clock information is transmitted further to base transceiver stations, whose frame transmissions are synchronised in accordance with the clock information. By using the implementation in accordance with the invention both economic and functional advantages are achieved, e.g. the capacity can be increased by up to 50-300%, depending on the manner of implementation.

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 reporting link information in a communication system including a communication terminal and a plurality of transceivers with each of which the communication terminal can communicate over a respective communication link; the method comprising: the communication terminal determining link information for each of the communication links; and the communication terminal periodically transmitting link messages, each link message containing link information for a first set of the communication links, and the link messages being formatted such that groups of successive link messages collectively contain link information for a larger set of the communication links.

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 present invention relates to estimation of a network indicator of a communication path between a first station and a second station in a communication system. A first indicator of the communication path in a direction from the first station to the second station is determined at the second station. A second indicator of the communication path in a direction from the second station to the first station is determined at the first station. Said second indicator associates to a corresponding feature of the communication path than said first indicator. A third indicator of the communication path in the direction from the first station to the second station is determined at the second station. The network indicator of the communication path in the direction from the second station to the first station is then estimated based on the determined first, second and third indicators.
