Femtocell Access Point Dynamic Load-Based Connection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional small cell femtocell access points inefficiently manage connections by limiting the maximum number of users, leading to malfunctioning and poor communication quality, as they do not account for varying data service capacities and service types, such as VoLTE and PSVT, resulting in unnecessary limitations even when system capacity is underutilized.
Innovation Solution
A flexible connection control method for femtocell access points that classifies user equipment based on service types (VoLTE, PSVT, and normal packet services) and calculates system load to determine whether to limit connections, prioritizing service continuity by managing connections according to service types when the system reaches maximum load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the maximum number of users is set in conventional femtocell access points, then connection management is simplified, but network efficiency deteriorates due to unnecessary limitations when system capacity is underutilized
Solution Approach 1:
The patent changes the parameter from a fixed maximum user count to a dynamic system load threshold. The FAP calculates system load based on data service capacity and compares it against a threshold to dynamically determine connection acceptance, allowing the system to adapt to varying utilization conditions and avoid unnecessary rejections when capacity is available
Solution Approach 2:
The patent introduces dynamic connection control by continuously monitoring system load and adjusting connection decisions in real-time. Instead of a static user limit, the system dynamically evaluates current data service capacity and makes connection decisions based on actual system conditions, enabling flexible adaptation to changing network states
2Quantity of substance
If connection is limited by maximum user count, then user capacity control is achieved, but communication quality deteriorates due to service type variations not being considered
Solution Approach 1:
The patent applies local quality by treating different service types (VoLTE, PSVT, packet services) with different weights in the system load calculation. Each service type contributes differently to the overall system load based on its data service capacity requirements, allowing the system to prioritize certain services over others and maintain communication quality for critical services even when user count is high
3Productivity
If system load is calculated based on service types, then network efficiency is improved, but device complexity increases due to additional calculation requirements
Solution Approach 1:
The patent implements partial action by calculating system load only for data services rather than all service types. The calculation focuses on services with significant data service capacity requirements (VoLTE, PSVT, packet services) while excluding services with minimal data requirements, reducing computational overhead while maintaining network efficiency improvements

AI summary
A flexible connection control femtocell access point device (100) of a small cell and a method of driving the same are provided. A maximum system load is used and network efficiency is maximized by calculating a system load occurring when a mobile station (UE) is newly connected according to the type of services that user equipments, that is, mobile stations, in a small cell, such as a femtocell, desire to use, comparing the calculated system load and the maximum system load, and determining whether to limit connection of the mobile station.
