Solution Overview

Problem

Existing wireless networks face challenges in managing cell capacity for fixed wireless devices, which tend to demand more bandwidth and can overload access nodes during handovers, leading to insufficient capacity and poor user experience.

Innovation Solution

Implementing a system where access nodes monitor and transmit notifications about the number of fixed wireless devices served, allowing neighboring nodes to deprioritize or exclude cells with high fixed wireless traffic during handover procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If access nodes accept handover requests from mobile devices without monitoring fixed wireless device counts, then handover flexibility is improved, but network capacity is exceeded and service quality deteriorates

Engineering Contradiction:

Improvehandover flexibilityVSAvoidnetwork capacity

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system performs preliminary monitoring of fixed wireless device counts at each access node before handover decisions are made. By提前获取和共享固定无线设备数量信息，网络可以预先识别容量受限的细胞，并在移动设备尝试切换到这些细胞之前做出明智的手动决策，从而避免过载

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Access nodes exchange feedback messages containing fixed wireless device count information with neighboring access nodes. This feedback mechanism enables dynamic adjustment of handover decisions based on real-time network conditions, allowing the system to adapt to changing capacity constraints while maintaining handover flexibility

Inventive Principle:

Principle #23Feedback

2Quantity of substance

If access nodes monitor and share fixed wireless device counts with neighboring nodes, then network capacity management is improved, but system complexity increases

Engineering Contradiction:

Improvenetwork capacityVSAvoidsystem complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The system uses existing standardized handover messages and interface protocols for sharing fixed wireless device count information. By leveraging universal communication mechanisms already present in the network infrastructure, the solution avoids introducing complex proprietary protocols while achieving effective capacity management

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system manages complexity by monitoring only the specific parameter of fixed wireless device count rather than comprehensive network state information. This focused parameter monitoring reduces the complexity of information exchange while still providing sufficient data for effective handover decisions

Inventive Principle:

Principle #35Parameter changes

AI summary

Systems and methods are provided for managing cell capacity for fixed wireless devices. An example method may include monitoring a number of fixed wireless devices on a frequency band served by an access node. If the number of fixed wireless devices on that frequency band exceeds a threshold, a notification may be transmitted to one or more neighboring access nodes. The notification may include the number of fixed wireless devices being served by the access node on the frequency band as well as the details of the frequency band that is serving the fixed wireless devices.
