Abstract: PROBLEM TO BE SOLVED: To provide a branch unit for underwater wavelength division multiplexing(WDM) optical communication system. SOLUTION: A branch unit 7 is provided with an optical switch 16 and an optical multiplexer 17, having several optical loop-back paths which pass through the switch 16. The switch 16 can be reconstructed, so that the switch 16 selectively couples individual channels for WDM signals to the trunk line output terminal of the branch unit 7. Since the unit 7 makes wavelengths and/or capacities reconstructible between main trunk lines and branch lines, the unit 7 can disconnect signals from the branch lines or increase the capacities of the branch lines, in response to changing requests from users.

Abstract: PROBLEM TO BE SOLVED: To provide a method which selects a cell when a mobile station accesses a mobile radio network of cellular system for its communication by deciding whether the relevant communication is transferred to a cell of another type, in response to the service type that is necessary for the communication.
SOLUTION: A mobile station selects a cell based on a cell selection algorithm (1). A network which corresponds to the cell of a prescribed type for the prescribed communication is accessed for the selected cell (2). Whether the relevant communication is transferred to a cell of another type constructing a better cell in terms of service (3) in addition to the signal switching necessary for establishment of communication (22, 23) is decided. If the transfer of communication has been decided, whether a candidate cell of another type can be selected (4) is decided. If a candidate cell that is not rejected is decided, the transfer of communication is commanded to the decided cell (6). In this way, the allocation of radio resources is optimized in a network.
