摘要

PROBLEM TO BE SOLVED: To provide a system and a technology for determining radio access technology (inter-RAT) coverage for energy saving management (ESM).SOLUTION: A network management (NM) device makes a decision when a source cell of a network of a first RAT is triggered so as to activate an energy saving state (ESS), and when the source cell is partially overlapped by a plurality of respective cells of one or more networks of one or more RATs different from the first RAT. In the case that a combination of a plurality of cells provides the coverage of the source cell, the NM device instructs the source cell to activate the energy saving state.SELECTED DRAWING: Figure 5
