Abstract: PROBLEM TO BE SOLVED: To provide a channel assignment method that takes a position of a terminal, a geographic characteristic of cells and also a moving characteristic of the terminal into account. SOLUTION: In the mobile communication system conducting space division multiplex access, a channel to be assigned to a terminal is decided by evaluating an assignment cost to each channel under the condition of re-use of channels. The cost is a function of a mean time that elapses between two consecutive channel assignment jobs to a terminal and then a channel maximizing the time is identified. The evaluation is conducted by using a cost coefficient that takes information relating to cell topology and information of terminal mobility into account. The cost coefficient is decided by re-dividing a cell into sectors in the initializing stage of the system and detecting the moment when cell collision between terminals takes place.

Abstract: In a mobile communication system with space division multiple access, under channel re-use conditions, the channel to be assigned to a terminal is determine d by evaluating a cost of the assignment of each channel already in use. This cost is a function of the mean time that elapses between two successive channel assignment s to the terminal, and it allows identifying the channel that allows maximising th at time. The evaluation is performed by using cost coefficients that take into account information on the topology of the cell and on the mobility of the terminals and are determined in a system initialisation phase by subdividing the cell into sectors and by detecting the instants of collision between terminals.
