Abstract:
1. A management method for radio resources in a radio communication system, wherein a first radio communications system features a first local functional unit for managing radio resources and a second radio communications system features a second local functional unit for managing radio resources, the first and second local functional units being divided into functional subunits, and the method comprises: with each of the first and second local functional units, signaling information relating to load measurements of the radio resources to a central functional unit for common radio resources management; evaluating the information with the central functional unit, and signaling information relating to a load target to at least one of the local functional units, and taking the information relating to the load target into account for an Inter System handover by the at least one of the local functional units; making a decision, with mobile functional subunits, about a time and/or a target of an Inter System handover and defining roles and/or parameters for Inter System handover with network-linked functional subunits communicating directly with the central functional unit on the basis of information received from the central functional unit; signaling the roles and/or parameters to the mobile functional subunits with the network-linked functional subunits; and taking into account the roles and/or parameters for the Inter System handover with the mobile functional subunits.
