Base Station Subordinate Cell Selection Using QoS and Terminal Type
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks lack a method to appropriately select subordinate base stations based on Quality of Service (QoS) or terminal type, leading to inefficient resource allocation and service quality issues.
Innovation Solution
A wireless communication system where a main base station selects subordinate base stations from candidates based on QoS or terminal type, using QoS-related information and terminal type information to determine the best communication resources for each terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a method for selecting subordinate base stations is not established, then any subordinate base station can be selected, but the appropriate subordinate base station cannot be selected from among a large number of candidates
Solution Approach 1:
The patent applies parameter changes by utilizing QoS parameters and terminal type parameters as selection criteria. The network device changes the selection parameters from random or arbitrary selection to selection based on specific parameters (QoS requirements and terminal type), thereby achieving accurate matching between subordinate base stations and terminal needs without increasing system complexity
Solution Approach 2:
The patent implements preliminary action by pre-establishing correspondence relationships between QoS parameters/terminal types and suitable subordinate base stations. The network device prepares selection criteria and correspondence tables in advance, so when selection is needed, it can directly query and select based on pre-defined parameters, avoiding complex real-time evaluation
2Reliability
If subordinate base stations are selected without considering QoS or terminal type, then the selection process is simple, but the required level of service quality cannot be ensured
Solution Approach 1:
The patent introduces QoS parameters and terminal type parameters as selection criteria, transforming the selection process from parameter-free random selection to parameter-based targeted selection. This ensures that the selected subordinate base station matches the terminal's service quality requirements while maintaining manageable system complexity through structured parameter correspondence
Solution Approach 2:
The network device performs self-service by autonomously selecting appropriate subordinate base stations based on QoS parameters and terminal type information. The system uses pre-configured correspondence relationships to automatically make selection decisions without requiring manual intervention or complex external coordination, thereby ensuring service quality while keeping the selection process efficient
3Adaptability or versatility
If a specified subordinate base station is always selected, then the selection is deterministic, but the flexibility to adapt to different terminal needs is reduced
Solution Approach 1:
The patent achieves adaptability through parameter changes by using different QoS parameters and terminal type parameters as selection basis. The network device can adjust selection strategies based on varying parameters (e.g., different QoS levels, different terminal types), providing flexibility to adapt to diverse terminal needs while maintaining simple operation through automated parameter-based selection
Solution Approach 2:
The patent implements dynamics by making the subordinate base station selection dynamic rather than static. The selection adapts to changing conditions (different QoS requirements, different terminal types) by querying pre-established correspondence relationships and selecting appropriate subordinate base stations based on current terminal characteristics, thereby achieving both flexibility and operational simplicity
Data Source
AI summary
The present invention is to enable setting of an appropriate subordinate cell or subordinate base station according to quality of a wireless communication service applied to a terminal or a type of a terminal. The terminal (3) is connected to a wireless communication network via a base station (1A), and when the base station (1A) sets another base station (1B or 1C) as the subordinate cell or the subordinate base station, the base station (1A) selects the subordinate cell or the subordinate base station from among either (a) candidates according to QoS (Quality of Service) applied to the terminal or (b) candidates according to the type of the terminal.
