Radio resource managament method and central controller in mobile radio communication system

摘要

A method of managing radio resources in a mobile radio communication system in which, in the course of management of radio resources between cells on the basis of a currently proposed hierarchical radio resource management method, radio resources in the system are divided into two groups by a central controller, static allocation of one group within these two groups of radio resources is effected among plural cells, and dynamic allocation of the other group within the two groups of radio resources is effected among plural cells in accordance with the various cell loads. The invention also provides a suitable central controller, and thereby makes it possible to give consideration both to the effectiveness of radio resource allocation and to the complexity of implementation when the central controller allocates radio resources among plural cells.
