Abstract

The invention relates to a management method for radio resources in a radio telecommunication system, in which a first radio telecommunication system has a first decentralized functional unit (serving RRM function) for managing radio resources, and a second radio telecommunication system has a second decentralized functional unit (neighbouring RRM function) for managing radio resources. The first and the second decentralized function unit signal information with respect to a work load (load measurements) of the radio resources to a central functional unit for common radio resource management (CRRM function). The central functional unit (CRRM function) evaluates this information (load measurements) and signals information with respect to load targets to at least one of the decentralized functional units, said information being taken into consideration by the decentralized functional unit in an intersystem handover (ISHO).
