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. A method of energy saving employed by an integration reference point (IRP) of a network manager (NM), comprising:
identifying an inter-radio access technology (RAT) energy-saving-coverage attribute corresponding to a target cell, wherein the inter-RAT energy-saving-coverage attribute is designated as IsESCoveredBy, and wherein a value of the IsESCoveredBy attribute includes at least one of “yes”, “no” or “partial”; and storing a “partial” value for the IsEScoveredBy 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 a source cell is about to be transferred to the energy saving state, wherein the source cell is of a network of a first RAT, the network of the first RAT is an evolved universal terrestrial radio access network (E-UTRAN), and the target cell is of a network of a second RAT different from the first RAT.
