Problem

Existing mobile communication network base stations lack the ability to dynamically adapt to the varying characteristics of the air interface and user demands, leading to suboptimal selection of communication standards and resource management.

Innovation Solution

A base station configured with a software defined radio module that considers the location, interference, and attenuation profiles of mobile terminals within its service area, allowing for dynamic selection of communication standards like GSM, UMTS, and LTE based on user capabilities, quality of service requirements, and available frequencies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a base station uses fixed communication standard configuration, then device complexity is reduced, but adaptability to different air interface characteristics deteriorates

Engineering Contradiction:
Improveadaptability to air interface characteristicsVSAvoidbase station configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base station dynamically selects communication standards (GSM, UMTS, LTE) based on real-time air interface characteristics including location, interference levels, and attenuation profiles. This dynamic adaptation allows the system to optimize performance for varying service conditions without requiring multiple fixed configurations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters by selecting different communication standards according to measured air interface characteristics. The base station evaluates location data, interference profiles, and attenuation characteristics, then adjusts the communication standard parameter to match current service area conditions.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If a base station dynamically adapts to air interface characteristics, then communication robustness is improved, but processing time and complexity increase

Engineering Contradiction:
Improvecommunication robustnessVSAvoidconfiguration decision time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The base station pre-calculates and stores interference and attenuation profiles for different service area locations. By having this information prepared in advance, the system can quickly determine the optimal communication standard without performing complex real-time calculations, thus reducing configuration decision time while maintaining robustness.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors air interface characteristics and uses this feedback to adjust communication standard selection. This closed-loop approach ensures that the base station maintains optimal performance by adapting to changing conditions while using efficient algorithms to minimize processing delays.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If a base station serves multiple communication standards, then versatility is improved, but resource management complexity increases

Engineering Contradiction:
Improvemulti-standard capabilityVSAvoidresource management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The service area is divided into segments with distinct interference and attenuation profiles. Each segment is associated with optimal communication standard selections, simplifying resource management by creating manageable zones rather than attempting to manage all standards uniformly across the entire coverage area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base station is designed with universal resource management capabilities that can handle multiple communication standards (GSM, UMTS, LTE) through a unified selection mechanism. This multi-functional design allows the same hardware and software infrastructure to support various standards, reducing overall complexity compared to having separate dedicated systems for each standard.

Inventive Principle:
Principle #6Universality (Multi-functionality)
