Edge Router Paging Control for Idle-Terminal Downlink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile edge computing networks face limitations in transmitting downlink traffic to terminals in an idle state, as the edge cloud site deployment at the back end of the base station does not support autonomous paging procedures for terminals in idle states.
Innovation Solution
An edge computing router that identifies terminals in an idle state and controls a paging procedure through a core network, utilizing a separate edge computing router located inside or outside the core network to transition the terminal to an active state, enabling the transmission of downlink traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the edge cloud site is deployed at the back end of the base station, then uplink traffic can achieve ultra-low latency, but downlink traffic cannot be transmitted to terminals in idle state
Solution Approach 1:
The patent introduces a paging controller as an intermediary component that mediates between the edge cloud site and the core network. This controller receives downlink traffic for idle terminals, determines their location area, and initiates paging procedures through the core network, enabling downlink transmission to idle terminals while maintaining the edge cloud's ultra-low latency uplink capability
Solution Approach 2:
The patent segments the network functionality by separating the paging control function from the traditional core network entities and placing it at the edge cloud site. This segmentation allows the edge cloud to independently handle downlink traffic for idle terminals by controlling the paging procedure, resolving the contradiction between uplink latency optimization and downlink transmission capability
2Use of energy by moving object
If the terminal remains in idle state to save energy, then power consumption is reduced, but downlink traffic cannot be received
Solution Approach 1:
The patent implements preliminary action by having the paging controller determine the terminal's location area (tracking area or cell) before initiating the paging procedure. This preliminary location determination enables efficient paging that can successfully reach idle terminals while allowing them to remain in low-power state, thus maintaining downlink reception capability without compromising energy savings
