Inter-rat coverage determination for energy saving management
First Claim
1. An apparatus to be employed as an integration reference point (IRP) manager by a network manager (NM), the apparatus comprising:
- one or more processors coupled with at least one memory, wherein at least one processor of the one or more processors is to execute instructions to;
determine whether a source cell is partially overlaid by a target cell, wherein the source cell is an evolved universal terrestrial radio access network (E-UTRAN) cell; and
store a “
partial”
value for an IsEScoveredBy attribute corresponding to the target cell if the target cell is associated with a different radio access technology (RAT) than the source cell and is to be 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 an energy saving state, wherein the IsEScoveredBy attribute is a an energy-saving coverage attribute.

Abstract
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.

7. One or more non-transitory computer-readable media having instructions that, when executed, cause an integration reference point (IRP) manager module of a network manager (NM) to:
-
determine whether a source cell associated with a radio access technology (RAT) is to activate an energy saving state, wherein the RAT associated with the source cell is an evolved universal terrestrial radio access network (E-UTRAN); access a set of stored energy-saving attributes that correspond to each of a plurality of target cells, wherein the energy-saving attributes that correspond to each of the plurality of target cells are designated as an IsESCoveredBy attribute; select a target cell having a different RAT than the source cell to be a candidate cell for handover from the source cell to the target cell when the IsESCoveredBy attribute of the target cell has a value of “
partial”
, wherein the “
partial”
value for the IsEScoveredBy attribute is to be stored in association with the target cell if the target cell is to be 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 an energy saving state; andinstruct the source cell to activate the energy saving state. - View Dependent Claims (8, 9, 10, 11, 12)

13. An apparatus to be employed as an integration reference point (IRP) agent by an evolved node B (eNB) associated with a first radio access technology (RAT), the apparatus comprising:
-
a memory having instructions; and one or more processors coupled with the memory, wherein at least one processor of the one or more processors is to execute the instructions to; provide state information to an IRP module of a network manager (NM) to indicate whether the eNB is in an energy saving state indicated by an IsESCoveredBy attribute associated with a cell of the eNB, wherein, when the cell is a source cell, a “
partial”
value is to be stored for an IsEScoveredBy attribute corresponding to a target cell if the target cell is of a different radio access technology (RAT) than the source cell and is to be 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 an energy saving state, and wherein the source cell is an evolved universal terrestrial radio access network (E-UTRAN) cell;receive an instruction to enter the energy saving state based on a determination made by the IRP module that the eNB is to enter the energy saving state; and initiate activation of the energy saving state in response to receipt of the instruction. - View Dependent Claims (14, 15, 16, 17, 18)

19. One or more non-transitory computer-readable media having instructions that, when executed, cause an integration reference point (IRP) agent of an evolved node B (eNB) associated with a first radio access technology (RAT), to:
-
provide state information to an IRP module of a network manager (NM) to indicate whether the eNB is in an energy saving state indicated by an IsESCoveredBy attribute associated with a cell of the eNB, wherein, when the cell is a target cell, a “
partial”
value is to be stored for an IsEScoveredBy attribute when the target cell is of a different radio access technology (RAT) than a source cell and is to be recommended along with at least one other target cell to be considered as an entirety of candidate cells to take over coverage of the source cell when the source cell is about to be transferred to an energy saving state, and wherein the source cell is an evolved universal terrestrial radio access network (E-UTRAN) cell;receive an indication that traffic handled by the source cell is to be handed over to the target cell and the other target cell based on a determination made by the IRP module that the source cell is to enter the energy saving state. - View Dependent Claims (20, 21, 22, 23, 24)
