Inter-rat coverage determination for energy saving management

摘要

Embodiments of systems and techniques are described for determining inter-radio access technology (inter-RAT) coverage for energy saving management (ESM). In some embodiments, a network management (NM) apparatus may determine that a source cell of a network of a first RAT is triggered to activate an energy saving state and that the source cell is partially overlapped by each of a plurality of cells of one or more networks of one or more RATs different from the first RAT. The NM apparatus may instruct the source cell to activate the energy saving state when a combination of the plurality of cells provides coverage of the source cell. Other embodiments may be described and claimed.

主权项

1. One or more non-transitory computer-readable media having instructions that, when executed, cause an integration reference point (IRP) manager module of a management apparatus to:
identify a source cell that supports inter-radio access technology (RAT) energy saving, the source cell of a network of a first RAT that is a universal mobile telecommunications system terrestrial radio access network (UTRAN) or an evolved universal terrestrial radio access network (E-UTRAN), wherein the source cell has a coverage area and a user equipment (UE) outside the coverage area cannot be covered by the source cell; identify a target cell that is proximate to the source cell, the target cell of a network of a second RAT that is different from the first RAT; store a first value for an energy-saving-coverage attribute corresponding to the target cell if the target cell is recommended to be considered as a single candidate cell to take over coverage when the source cell is about to be transferred to an energy saving state, wherein the target cell is recommended to be considered as a single candidate cell when a coverage area of the target cell encompasses the coverage area of the source cell; and store a second value, different from the first value, for the energy-saving-coverage attribute corresponding to the target cell if the target cell is recommended along with at least one other target cell to be considered as an entirety of candidate cells to take over coverage when the source cell is about to be transferred to the energy saving state, wherein the target cell is recommended along with at least one other target cell to be considered as an entirety of candidate cells when a combination of coverage areas of the target cell and the at least one other target cell encompasses the coverage area of the source cell, and wherein the target cell and the at least one other target cell have different coverage areas.
