Network Entity Congestion State Selection for Wireless Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in network access and signaling overhead during congestion states, leading to service interruptions and delayed access for user equipment.
Innovation Solution
A method that involves receiving state information from adjacent network entities, selecting a non-congested entity for network access, and transmitting access information to user equipment, including activation of Idle mode Signalling Reduction (ISR) to reduce unnecessary signaling and optimize network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network entity directs user equipment to adjacent network entities for access, then network access reliability is improved, but device complexity increases
Solution Approach 1:
The network entity pre-collects state information from adjacent network entities before congestion occurs. This preliminary action enables the network entity to have ready information about alternative access points, allowing it to quickly redirect user equipment to non-congested entities when needed, thereby improving reliability without adding operational complexity
Solution Approach 2:
The network entity acts as an intermediary that mediates between user equipment and multiple adjacent network entities. It collects state information from neighbors and makes intelligent routing decisions, simplifying the overall system by centralizing the decision-making logic rather than requiring complex interactions between all components
2Reliability
If state information is collected from multiple network entities, then network access reliability is improved, but information processing overhead increases
Solution Approach 1:
The network entity extracts only the essential state information (congestion status, load conditions) from adjacent network entities rather than collecting all possible data. This selective extraction reduces information processing overhead while maintaining sufficient data for making reliable access decisions
Solution Approach 2:
The system collects state information periodically or triggered by specific events rather than continuously monitoring all parameters. This partial monitoring approach reduces signaling overhead while still providing timely information for network access decisions when needed

AI summary
Disclosed is a communication method of a network entity, which comprises: receiving state information from a plurality of neighboring network entities; selecting one network entity, which is not in a congestion state, among the plurality of network entities for a network access of a terminal, on the basis of the state information; and transmitting, to the terminal, a message including information for accessing of the terminal to the selected network entity.
