Wireless Paging Zone Redirection for Access Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks experience congestion and slower response times due to heavy registration traffic and delivery of paging information, leading to dropped or blocked communication sessions when multiple devices communicate through a single wireless access node.
Innovation Solution
A method and system that monitor wireless access nodes for congestion and instruct adjacent nodes to toggle between broadcasting different paging zone identifiers at a predetermined duty cycle to alleviate congestion by redistributing paging information across adjacent zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paging information is delivered through a single wireless access node, then paging information can be delivered to devices in that zone, but congestion arises and response times slow down
Solution Approach 1:
The paging zone is segmented into multiple sub-zones, each served by a different wireless access node. When congestion is detected at the first access node, the system divides the original paging zone identifier into multiple sub-zone identifiers and redirects paging information to the second access node, effectively segmenting the traffic load across multiple nodes to improve response time while maintaining reliable delivery.
2Adaptability or versatility
If multiple wireless communication devices communicate through a single wireless access node, then devices can access the network, but congestion causes difficulty in delivery of paging information
Solution Approach 1:
The system introduces a paging zone identifier redirection mechanism as an intermediary layer between the paging information source and the wireless access nodes. When congestion is detected, the system mediates by redirecting paging information through a different access node using sub-zone identifiers, ensuring reliable delivery even when multiple devices are communicating through a single node.
3Productivity
If wireless access nodes are grouped into paging zones, then paging information delivery is efficient, but heavy registration traffic causes slower response times
Solution Approach 1:
The system dynamically adjusts paging zone assignments based on real-time congestion conditions. Instead of static paging zone groupings, the system monitors congestion levels and dynamically redirects paging information to different access nodes using sub-zone identifiers, allowing the network to adapt to changing traffic conditions and maintain efficient delivery while reducing response time loss.
Data Source
AI summary
What is disclosed is a method of operating a wireless access control system. The method includes monitoring a first wireless access node to determine when the first wireless access node experiences wireless access congestion, where the first wireless access node broadcasts a first paging zone identifier for receipt by wireless communication devices receiving wireless access from the first wireless access node. The method also includes, in response to the wireless access congestion at the first wireless access node, instructing a second wireless access node which broadcasts a second paging zone identifier to toggle between broadcasting the first paging zone identifier and broadcasting the second paging zone identifier at a first duty cycle.
