Inter-RAT Base Station Energy Savings Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current energy savings methods for base stations do not effectively address energy efficiency in multi-system covering networks, particularly for inter-RAT base stations, leading to increased manufacturing costs and inadequate energy savings in some cases, with no existing technical scheme focusing on inter-RAT energy savings.
Innovation Solution
A method and apparatus for energy savings control in inter-RAT base stations that involve obtaining status information from foreign system cells, performing energy savings control judgments based on local and foreign system cell status, and adjusting the operational state (hibernation or wake-up) of cells to optimize energy usage without affecting user access, using dedicated messages or existing communication protocols between base stations and the core network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If new energy savings devices and heat dissipation modification are adopted, then power consumption is reduced, but manufacturing cost increases
Solution Approach 1:
The base station performs self-energy-saving by autonomously determining its own energy-saving status based on service requirements and neighboring cell information, without requiring external control devices or complex modifications. The control method enables the system to self-regulate power consumption through intelligent decision-making algorithms that assess traffic conditions and coordinate with neighboring cells.
Solution Approach 2:
The invention changes the operational parameters of the base station by dynamically adjusting the working status (active, sleep, hibernate modes) based on service requirements and neighboring cell states. This parameter-based control allows flexible power management without physical modifications to the hardware, avoiding increased manufacturing costs while achieving energy savings.
2Reliability
If base stations operate continuously to ensure user access, then service reliability is maintained, but energy consumption increases
Solution Approach 1:
The base station dynamically adjusts its operational status between active, sleep, and hibernate modes based on real-time service requirements and neighboring cell conditions. This dynamic adaptation allows the system to maintain reliability when needed while reducing power consumption during low-traffic periods, creating a flexible balance between service availability and energy usage.
Solution Approach 2:
The invention implements a feedback mechanism where base stations exchange information about their working status and service conditions with neighboring cells. This feedback loop enables coordinated energy-saving decisions, ensuring that user access is maintained through neighboring cells when one cell enters energy-saving mode, thus preserving reliability while enabling power reduction.
3Loss of energy
If inter-RAT coordination is implemented for energy savings, then energy efficiency improves, but system complexity increases
Solution Approach 1:
The energy-saving control method is designed to be universally applicable across different RAT types (2G, 3G, 4G, 5G) and can be implemented in heterogeneous network environments. The same control logic and message exchange mechanisms work across multiple radio access technologies, reducing the need for RAT-specific complex implementations while achieving energy savings across the entire inter-RAT network.
