Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication systems using millimeter wave frequency bands, the increased number of base stations and decreased cell size lead to data traffic overload and decreased energy efficiency due to frequent handovers, necessitating a more efficient method for base station grouping and network reconfiguration without a central controller.
Innovation Solution
An operation method for intelligent base stations that dynamically determine the need for reconfiguration based on terminal movement, allowing nearby base stations to join or leave the group, optimizing network traffic and quality of service through distributed cooperation without a central controller, using communication interfaces and processors to manage network information and identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of base stations is increased to support more terminals in millimeter wave frequency bands, then the data transmission rate is improved, but the network management complexity increases and energy efficiency decreases
Solution Approach 1:
The patent divides the network into intelligent base station groups, where each group independently manages a subset of terminals. This segmentation reduces the overall network management complexity by distributing management responsibilities across multiple autonomous groups rather than requiring centralized control of all base stations.
Solution Approach 2:
Intelligent base stations autonomously determine when reconfiguration is needed based on terminal movement information, and independently execute join or leave operations without centralized control. This self-service capability reduces network management complexity while maintaining high data transmission rates across the expanded network.
2Productivity
If fixed base stations are used to support increasing number of terminals, then coverage is provided, but data traffic overload occurs and energy efficiency decreases
Solution Approach 1:
The patent introduces dynamic base station groups where intelligent base stations can join or leave based on real-time terminal movement and traffic conditions. This dynamic reconfiguration allows the network to adapt to varying traffic loads, preventing overload conditions and improving energy efficiency by activating only the necessary base stations.
Solution Approach 2:
The system changes the operational state of base stations from fixed to variable, where base stations dynamically adjust their participation in groups based on traffic demand and terminal locations. This parameter change enables the network to scale capacity efficiently while maintaining energy efficiency.
3Reliability
If frequent handovers are implemented in ultra-dense networks, then terminal connectivity is maintained, but network management complexity and energy consumption increase
Solution Approach 1:
The patent implements preliminary actions by having intelligent base stations proactively monitor terminal movement information and predict when handovers or group reconfigurations will be needed. This allows the system to prepare for connectivity transitions in advance, maintaining reliable terminal connectivity while reducing the complexity of reactive network management.
Solution Approach 2:
The system uses feedback from terminal movement information to trigger intelligent base station group reconfigurations. This feedback mechanism ensures terminal connectivity is maintained by responding to actual movement conditions, while reducing unnecessary handovers and their associated management complexity.
4Reliability
If base station groups are reconfigured based on terminal movement, then quality of service is improved, but communication overhead between base stations increases
Solution Approach 1:
The patent implements local quality by having each intelligent base station group independently make reconfiguration decisions based on local terminal movement information within that group. This localized decision-making improves quality of service for local terminals while minimizing communication overhead by avoiding centralized coordination for every reconfiguration event.

AI summary
A communication method and apparatus for communicating with an intelligent base station in a wireless communication system are provided. An operation method of the intelligent base station includes determining whether reconfiguration of an intelligent base station group that supports a terminal is necessary, according to movement information of the terminal, the determination being performed by a first intelligent base station included in the intelligent base station group, when the first intelligent base station determines that reconfiguration of the intelligent base station group is necessary, transmitting a join request to join the intelligent base station group, to a nearby intelligent base station not included in the intelligent base station group, receiving a join approval message in response to the transmitted join request, and reconfiguring the intelligent base station group, based on the received join approval message.
