Network Congestion Management Service for Wireless Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless nodes, such as base stations, can experience congestion due to resource limitations, leading to service denial for attached mobile devices, especially for critical real-time services, as devices fail to switch to alternative radio access technologies (RATs) due to strong LTE coverage masking congestion issues.
Innovation Solution
Implementing a network congestion management service where wireless nodes broadcast periodic messages indicating their congested or non-congested state, allowing user devices to switch between LTE and CDMA communication interfaces to avoid call failures by proactively selecting a non-congested network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If mobile devices rely on strong LTE coverage to obtain service, then coverage quality is improved, but service availability deteriorates during network congestion
Solution Approach 1:
The patent implements preliminary action by having the network proactively broadcast congestion status information before service denial occurs. Mobile devices receive advance notice of congestion conditions and can pre-switch to alternative RATs or cells, preventing service failure rather than reacting after connection loss
Solution Approach 2:
The patent establishes a feedback mechanism where the network continuously broadcasts congestion status information to mobile devices. This real-time feedback enables devices to monitor network conditions and dynamically adjust their connection strategy by switching to alternative RATs or less congested cells based on received congestion indicators
2Stability of the object's composition
If mobile devices remain attached to congested base stations, then connection stability is maintained, but service quality deteriorates
Solution Approach 1:
The patent applies dynamics by enabling mobile devices to dynamically adjust their connection behavior based on real-time congestion status information. Devices can transition between different RATs (LTE, CDMA, WCDMA) and select different cells based on broadcast congestion indicators, making the connection strategy adaptive rather than static
Solution Approach 2:
The patent implements parameter changes by modifying the connection parameters (RAT selection, cell selection) based on congestion status information. When congestion is detected, devices change their operational parameters to connect to alternative networks or less congested cells, optimizing service quality while maintaining connection stability
3Reliability
If multi-RAT user devices switch to alternative networks during congestion, then service availability is improved, but device complexity increases
Solution Approach 1:
The patent uses an intermediary approach by introducing standardized congestion status information broadcasting as a mediator between the network and mobile devices. This standardized mechanism simplifies the complexity of multi-RAT management by providing a unified interface for congestion awareness and automated switching decisions, reducing the burden on device intelligence

AI summary
A method, a device, and a non-transitory storage medium having instructions to attach to a user device, wherein the network device provides wireless access coverage in a cell area or a sector area of a first network; detect whether the network device is in a congested state; generate a message that indicates that the network device is in the congested state when the network device is in the congested state; and transmit the message on a control or signaling channel for receipt by user devices attached to the network device in the cell area or the sector area. The user device scans the control or signaling channel before initiating a session and determines whether the network device is in the congested state. When the network device is in the congested state, the user device performs a switchover to a second network. The user device has multimode capabilities.
