Antenna Array Control via Multiple AISG Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna control systems are limited in their ability to flexibly control multiple antenna arrays, as they often require a single Radio Unit (RU) device for tilt angle adjustments, which can lead to control failures if the RU is faulty or during maintenance, and cannot support multiple control ports in network deployments.
Innovation Solution
The proposed solution involves an antenna array control apparatus with multiple Antenna Interface Standards Group (AISG) interfaces and a link establishing unit that establishes communications links between electric motors and modems based on antenna array configuration signals, allowing for flexible control of multiple antenna arrays using multiple AISG interfaces as control ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single RU device is used to control all antenna arrays, then the number of connection lines is reduced, but the system reliability deteriorates when the RU device is faulty or under maintenance
Solution Approach 1:
The patent divides the control system into multiple independent control units (RU devices), each capable of controlling specific antenna arrays. This segmentation allows control functions to be distributed across multiple devices, so that if one RU device fails or is under maintenance, other RU devices can still control their respective antenna arrays, thereby improving system reliability while maintaining manageable connection complexity.
Solution Approach 2:
The patent changes the parameter of control port quantity from one to multiple. By enabling multiple RU devices to serve as control ports simultaneously, the system allows flexible configuration where different RU devices can control different antenna arrays based on network deployment requirements, thus improving reliability without significantly increasing connection complexity.
2Device complexity
If a single RU device controls all antenna arrays, then device complexity is reduced, but the adaptability to network deployment requirements deteriorates when multiple control ports are needed
Solution Approach 1:
The patent makes RU devices universal by enabling multiple RU devices to perform the same control function for different antenna arrays. Each RU device can independently control one or more antenna arrays, providing multi-functionality that adapts to various network deployment scenarios requiring different numbers of control ports, thereby improving versatility without complicating the control structure.
Solution Approach 2:
The patent changes the parameter of control port quantity from fixed (one) to variable (multiple). This allows the system to adapt to different network deployment requirements by configuring an appropriate number of RU devices as control ports, enhancing versatility while maintaining a relatively simple control structure through standardized interfaces and protocols.
3Adaptability or versatility
If multiple AISG interfaces are used to control multiple antenna arrays, then control flexibility is improved, but device complexity increases
Solution Approach 1:
The patent segments the control system into multiple independent control units (AISG interfaces on different RU devices), each managing specific antenna arrays. This segmentation provides control flexibility and versatility while keeping each individual control unit relatively simple, thereby managing overall device complexity through modular architecture.
