Cell Selection via Session Matching Level for Load Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication network technologies face challenges in maintaining spectral efficiency while reducing call dropping and blocking rates, particularly when users are forced to switch to adjacent cells, which can lead to reduced spectral efficiency and poor user experience.
Innovation Solution
A method that calculates a session matching level for each cell based on session type, data rate, and load balance parameters, allowing user terminals to selectively access the most suitable cell, thereby adapting to varying network loads and avoiding overloaded cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users are forced to switch to adjacent cells by adjusting switching parameters to reduce load, then call dropping rate/blocking rate is reduced, but spectral efficiency is reduced
Solution Approach 1:
The patent introduces a session matching level parameter that combines multiple factors (session type, data rate, load balance parameters) to dynamically adjust cell selection criteria. This allows the network to flexibly change selection parameters based on current network conditions and user requirements, resolving the contradiction between load balancing and spectral efficiency by finding optimal trade-off points through parameter optimization
Solution Approach 2:
The patent implements a feedback mechanism where the network calculates session matching levels based on real-time network state information and user session characteristics. The network uses this feedback to dynamically adjust cell selection decisions, allowing continuous optimization of both call success rate and spectral efficiency based on actual network conditions rather than static parameters
2Productivity
If switching parameters are adjusted to migrate users from overloaded cells, then load balance is improved, but user experience deteriorates due to reduced spectral efficiency
Solution Approach 1:
The patent applies local quality by considering different session types and data rate requirements when calculating session matching levels. Instead of uniform load balancing, the system tailors cell selection criteria to local network conditions and user-specific requirements, ensuring that users receive appropriate service quality while achieving overall load balance
Solution Approach 2:
The patent makes the cell selection process dynamic by continuously calculating session matching levels based on real-time network state changes. The system adapts its load balancing strategy dynamically according to current network conditions, user movement, and session characteristics, thereby maintaining both good load balance and user experience rather than relying on static parameters

AI summary
A method for accessing to a mobile communication network, comprising: acquiring a session matching level for each cell, which is calculated based on a session type of a session initiated by a user terminal as needed, a session data rate available to the user terminal of each cell and load balance parameters of each cell; accessing to a cell selected according to the session matching level for each cell. Further, it also provides another method for accessing to a mobile communication network, and corresponding user terminal, network-side device and communication system.
