RAN Paging Deactivation for Stable 5G Initial Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transitioning to 5G wireless systems with Dual Connectivity (DC) is challenging under a multi-vendor environment, particularly when one master node uses high frequencies, making it inefficient to use for paging, necessitating a method to deactivate paging in specific Radio Access Network (RAN) nodes.
Innovation Solution
A network node is provided with a transmission unit to send a configuration request including a paging deactivation indication to the Access and Mobility Management Function (AMF) and a reception unit to receive a response, transmitting broadcast information to deactivate paging in specific RAN nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Dual Connectivity is adopted to stabilize initial coverage during 5G deployment, then coverage stability is improved, but implementation difficulty increases under multi-vendor environments
Solution Approach 1:
The patent extracts the paging function from the high-frequency master node and relocates it to a low-frequency master node. This separation allows the high-frequency node to focus on data transmission while the low-frequency node handles paging, thereby stabilizing initial coverage without requiring complex multi-vendor DC implementation.
Solution Approach 2:
The patent applies different frequency characteristics to different functional roles: low-frequency nodes are designated for paging operations due to their better coverage properties, while high-frequency nodes are dedicated to data transmission. This local optimization of frequency usage resolves the contradiction between coverage stability and implementation complexity.
2Speed
If a high-frequency master node is used for data transmission, then transmission speed is improved, but paging efficiency deteriorates
Solution Approach 1:
The patent segments the master node functions into two separate nodes: one dedicated to paging operations and another dedicated to data transmission. This functional segmentation allows each node to be optimized for its specific purpose, enabling high-speed data transmission on high-frequency nodes while maintaining effective paging on low-frequency nodes.
Solution Approach 2:
The patent assigns different frequency characteristics to different functional roles: low-frequency nodes are designated for paging operations due to their better coverage properties, while high-frequency nodes are dedicated to data transmission. This local optimization of frequency usage resolves the contradiction between coverage stability and implementation complexity.
3Loss of energy
If paging is deactivated on a high-frequency master node, then resource efficiency is improved, but coverage stability may worsen
Solution Approach 1:
The patent extracts the paging function from the high-frequency master node and relocates it to a low-frequency master node. This separation allows the high-frequency node to focus on data transmission while the low-frequency node handles paging, thereby stabilizing initial coverage without requiring complex multi-vendor DC implementation.
Solution Approach 2:
The patent introduces a low-frequency master node as an intermediary to handle paging operations. This intermediary node provides the coverage stability that would otherwise be lost by deactivating paging on high-frequency nodes, while still allowing resource-efficient high-frequency data transmission.

AI summary
A network node includes: a transmission unit configured to transmit a configuration request including a paging deactivation indication to an AMF (Access and Mobility Management Function); and a reception unit configured to receive a response to the configuration request from the AMF. The transmission unit transmits broadcast information including a paging deactivation indication to a terminal.
