Method and system for smart operating bandwidth adaptation during power outages

A method for adaptive bandwidth (BW) management, comprising:

• configuring an element management control unit comprising a set of distribution (DU) and central units (DU/CU) for monitoring power and traffic loads at a plurality of cell sites in a network;
• managing, by a slice management unit, a set of network slices at the plurality of cell sites, and determining based on information about power and traffic loads received from the element management control unit, whether a change in state is occurring that will cause a power outage or light load operation at a node of at least one cell site of the plurality of cell sites;
• and
• in response to a determination of the change in state at the at least one cell site, initiating by the slice management unit, a network slice reassignment process at the at least one cell site for reassigning a set of network slices at the at least one cell site to smaller bandwidth parts (BWPs), wherein each reassigned network slice is tied to a respective BWP to enable a transfer of loads from a set of network slices in an active state at the least one cell site to a set of BWPs thereby reducing overall power consumption of a node which comprises the at least one cell site.

A computer program product tangibly embodied in a non-transitory, computer-readable storage device that stores a set of instructions that when executed by a processor perform a method for an operational mode of a base station when a power loss or light network load is detected, the method comprising:

• configuring an element management control unit comprising a set of distribution and central units (DU/CU) for monitoring power and user traffic at a plurality of cell sites in the network;
• managing, by the processor disposed in a slice management unit, a set of network slices at the plurality of cell sites, and determining based on information about power and traffic loads received from the element management control unit, whether a change in state is occurring that will cause a power outage or light load operation at a node of at least one cell site of the plurality of cell sites;
• and
• in response to a determination of the change in state at the at least one cell site, initiating by the processor, a network slice reassignment process at the at least one cell site for reassigning a set of network slices at the at least one cell site to smaller bandwidth parts (BWPs), wherein each reassigned network slice is tied to a respective BWP to enable a transfer of loads from a set of network slices in an active state at the least one cell site to a set of BWPs thereby reducing overall power consumption of a node which comprises the at least one cell site.
