Base Station Energy Saving Management via Centralized IRP Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators are unable to deploy energy-saving (ES) strategies for base stations from the perspective of overall network load statistics or performance status, limiting the effectiveness of ES operations.
Innovation Solution
An ES management method and system that utilizes an integration reference point manager (IRPManager) to send ES enable/disable attribute information and effective period settings to an integration reference point agent (IRPAgent) through a northbound interface, allowing unified management and enhanced decision-making for ES operations across base stations and cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If base station self-monitors load status to trigger ES operation, then ES operation can be performed, but operators are unable to deploy ES strategy from network perspective
Solution Approach 1:
The patent introduces a network management system as an intermediary between base stations and operators. This mediator collects load status information from multiple base stations, processes it centrally, and sends back ES control instructions. This resolves the contradiction by enabling network-wide ES strategy deployment while maintaining base station ES operation capability through the intermediary management layer.
Solution Approach 2:
The patent transitions from single-base-station self-monitoring to network-wide centralized monitoring by adding a new dimension of management hierarchy. The network management system operates at a higher organizational level, aggregating data from multiple base stations and providing coordinated ES control across the entire network, thus enabling operators to deploy ES strategies from network perspective.
2Loss of energy
If base station turns off energy-consuming components in low load, then energy consumption is reduced, but network performance may be impacted
Solution Approach 1:
The patent implements a feedback mechanism where the network management system continuously monitors load status of base stations and dynamically adjusts ES operation instructions accordingly. When load increases, the system sends instructions to activate components; when load decreases, it permits ES operations. This feedback loop ensures network performance is maintained while enabling energy savings, resolving the contradiction between energy reduction and performance reliability.

AI summary
An energy saving (ES) management method for a base station, an ES method for a base station, and an apparatus and a system are used to solve the problem that currently operators are unable to deploy an ES strategy for a base station from the perspective of overall load statistics or performance status of a network. The ES management method for a base station includes: An integration reference point manager (IRPManager) initiates an ES enable/disable procedure or an ES activation/resumption procedure to an integration reference point agent (IRPAgent), where the ES enable/disable procedure is used to allow or prohibit an ES operation on the base station or a cell, and the ES activation/resumption procedure is used to cause the base station or the cell to go into or go out of an ES state. The technical solutions according to the embodiments of the present invention enable operators to perform unified management on an ES procedure for a base station at a base station level or a cell level.
