Access Network Control Device Energy Saving via User Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication networks, the coexistence of high-speed and low-speed transmission networks complicates energy-saving efforts, as existing methods for controlling access network devices lack flexibility, leading to suboptimal communication services due to overload and other issues.
Innovation Solution
A method and apparatus that obtain status information from multiple mobile communication networks and user parameters to strategically turn off or on access network devices, ensuring seamless handovers between networks like 2G, 3G, and 4G, thereby improving control flexibility and maintaining normal communication services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If an access network device is periodically turned off to save energy, then energy consumption is reduced, but communication service reliability deteriorates due to overload and inability to provide normal service
Solution Approach 1:
The controller performs preliminary actions by obtaining status information of radio access network devices and users before turning off the access network device. Users are migrated to other networks in advance, ensuring that when the device is turned off, no users are left without service, thus preventing communication service failures while achieving energy saving
Solution Approach 2:
The controller acts as an intermediary that coordinates between multiple mobile communication networks. It manages user migration by notifying radio access network control devices in other networks, ensuring seamless handover and maintaining service reliability during the energy-saving operation
2Loss of energy
If an access network device is turned off for energy saving, then energy consumption is reduced, but control flexibility deteriorates
Solution Approach 1:
The system dynamically adjusts the operation state of access network devices based on real-time status information. The controller can flexibly decide when to turn devices off or on, and which users to migrate, adapting to changing network conditions and user requirements, thus maintaining control flexibility while achieving energy saving
Solution Approach 2:
The controller changes operational parameters by selectively turning off specific functional modules of access network devices based on user migration status and network conditions. This parameter adjustment allows flexible energy management without compromising overall system controllability
