Cellular Network Element Service Class Handover Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular telecommunications systems lack the ability to perform service-type specific load balancing between LTE cells, as all users are treated equally regardless of their Quality of Service (QoS) requirements, leading to inefficient network resource allocation and potential service disruptions.
Innovation Solution
Implementing a network element that assigns class-specific cell configuration parameters based on user service requests, allowing for differentiated handover settings and load balancing strategies tailored to specific service classes, which enables more efficient resource allocation and improved Quality of Service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single set of handover configuration settings is used for all users, then the system complexity is reduced and ease of operation is improved, but the ability to perform service-type specific load balancing is lost and network efficiency deteriorates
Solution Approach 1:
The patent segments the single handover configuration setting into multiple class-specific handover configuration settings, where each setting is tailored to specific service classes (e.g., real-time vs. non-real-time services). This segmentation enables differentiated handover behavior for different user types, improving network efficiency while managing complexity through structured organization of parameters.
Solution Approach 2:
The patent applies local quality by assigning different handover configuration parameters to different service classes. Instead of uniform settings for all users, the system provides customized handover settings (such as different Time To Trigger values, handover margins, or measurement filter coefficients) based on the specific service requirements of each user class, optimizing performance for each local group.
2Ease of operation
If all users are treated equally regardless of service class, then the system is simpler to operate, but Quality of Service optimization and load balancing effectiveness deteriorate
Solution Approach 1:
The patent implements local quality by treating different user classes differently based on their service requirements. The system identifies service classes (real-time, non-real-time, etc.) and applies customized handover policies to each class, ensuring that critical services receive prioritized treatment while maintaining simplicity through automated classification and policy application.
Solution Approach 2:
The patent introduces dynamic user treatment by enabling the system to adapt handover parameters based on the detected service class of each user. The handover behavior becomes dynamic rather than static, allowing the network to adjust timing, thresholds, and other parameters in real-time based on service requirements, thereby improving QoS while maintaining ease of operation through automated decision-making.
3Productivity
If service class dependent handover parameters are implemented, then load balancing effectiveness and network efficiency are improved, but configuration complexity and parameter management burden increase
Solution Approach 1:
The patent manages configuration complexity by segmenting the handover parameters into distinct sets associated with different service classes. Each service class has its own configured parameters, making the system more manageable through structured organization. The segmentation allows independent optimization of each class without affecting others, improving load balancing while maintaining configurability.
Solution Approach 2:
The patent applies universality by designing a framework where a single network element can manage multiple service classes through a unified mechanism. The system uses a common handover decision architecture that accommodates different parameters for different classes, allowing one network element to serve multiple functions (handling real-time, non-real-time, and other service types) without requiring separate dedicated systems for each class.
