Solution Overview
Problem
Current wireless communication systems face high paging loads and inefficiencies in locating stationary or low mobility devices, leading to increased battery consumption and network congestion due to the need to broadcast paging messages across multiple cells.
Innovation Solution
Implementing Enhanced Paging Identification (EPI) information that allows for precise tracking of wireless devices' locations and mobility status, enabling paging requests to be transmitted only to the relevant base station and cell, thereby reducing unnecessary network traffic and battery drain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paging requests are broadcast across multiple cells to ensure device location, then device reachability is improved, but network load and battery consumption increase
Solution Approach 1:
The patent segments the paging process by introducing Enhanced Paging Identification (EPI) information that divides devices into stationary and mobile categories. This segmentation allows the network to apply different paging strategies: targeted single-cell paging for stationary devices and traditional multi-cell paging for mobile devices, thereby reducing unnecessary energy consumption while maintaining reliability
Solution Approach 2:
The patent applies local quality by treating stationary and mobile devices differently through the EPI mechanism. Stationary devices receive localized paging in their current cell only, while mobile devices continue to receive paging across multiple cells. This differentiated approach optimizes energy efficiency for stationary devices without compromising the reachability of mobile devices
2Reliability
If paging requests are broadcast across multiple cells to ensure device location, then device reachability is improved, but network congestion increases
Solution Approach 1:
The patent segments the paging traffic by introducing EPI information that categorizes devices as stationary or mobile. This segmentation enables the network to send paging requests only to the current cell for stationary devices, significantly reducing the quantity of paging traffic across the network while maintaining reliable delivery
Solution Approach 2:
The patent extracts the mobility status information from the traditional paging process through the EPI mechanism. By extracting and utilizing this information, the system can remove unnecessary paging transmissions to cells where stationary devices are not located, thereby reducing network congestion while preserving device reachability
3Device complexity
If traditional paging is used without location tracking, then network complexity is reduced, but paging efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by having devices report their stationary/mobile status and current cell information to the network in advance through the EPI mechanism. This preliminary information gathering enables the network to make efficient paging decisions without increasing operational complexity, thereby improving paging efficiency
Solution Approach 2:
The patent changes the parameter of device classification by introducing EPI information that tracks mobility status. This parameter change enables the network to optimize paging efficiency by targeting stationary devices with single-cell paging while maintaining compatibility with traditional multi-cell paging for mobile devices
