Abstract:
An arrangement for handling radio communication in a number of cells that serve a number of mobile stations in a cellular communication network, in which a number of radio channels are assigned as control channels and traffic channels, the arrangement comprising:means for assigning traffic channels;means for storing cell parameter information including handover parameters;means for holding signal strength information; andload monitoring means for holding information about traffic load in at least a number of cells;wherein the traffic channel assigning means comprises means for using signal strength values and cell assignment parameters to establish if there are any neighboring cells available as cell candidates for a mobile station accessing an access cell, and traffic load information for the access cell and such available cells is used such that a mobile station accessing an access cell can be assigned a traffic channel in one of the available cells based on the traffic load in the cells; andwherein handover parameters are added to or subtracted from the signal strength values received from the mobile station in an initial access message provided to the access cell to establish whether the mobile station is in the handover area between the access cell and at least one neighboring cell, and if yes, the neighboring cell(s) form(s) (an) available cell candidate(s).
