Cross-Network Paging Identification Between Public and Private Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of efficient paging in multi-beam systems, particularly in scenarios involving both public and non-public networks, where user equipment (UE) needs to transition seamlessly while maintaining service continuity across network types.
Innovation Solution
A communication method and apparatus that enable UE to determine the network type associated with a paging message, allowing for efficient power control and power headroom reporting by utilizing network identifiers and configuration information to manage cell reselection and service capability, thereby facilitating seamless transitions between public and non-public networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the UE camps on a first network and receives a paging message, then the UE can be paged in the current network, but the UE cannot determine which network type (public or non-public) the paging message is associated with without additional information
Solution Approach 1:
The patent embeds network type identification information within the existing paging message structure. The indication information is nested inside the paging message, allowing the UE to determine the network type (public or non-public) without requiring a separate signaling mechanism. This resolves the contradiction by adding information content while maintaining the integrated paging message format.
Solution Approach 2:
The patent introduces indication information as an intermediary element within the paging message. This intermediary carries the network type identification and enables the UE to distinguish between public and non-public network paging without fundamentally changing the paging mechanism. The indication information acts as a mediator that bridges the existing paging infrastructure with the need for network type differentiation.
2Adaptability or versatility
If the UE supports both public and non-public networks, then the UE can access both network types, but the UE cannot efficiently manage power control and service continuity when moving between network types
Solution Approach 1:
The patent enables the UE to determine the network type associated with a paging message before attempting to access or transition between networks. By obtaining network type identification information from the paging message in advance, the UE can prepare appropriate power control parameters and service continuity mechanisms specific to the target network type, avoiding unnecessary power consumption from trial-and-error network access attempts.
Solution Approach 2:
The patent allows the UE to adjust power control parameters and service management settings based on the determined network type. When the UE identifies whether the paging message is from a public or non-public network, it can switch between different power management profiles and service configurations optimized for each network type, thereby reducing overall power consumption while maintaining multi-network adaptability.
3Reliability
If the paging message does not include network type identification, then the paging message structure remains simple, but the UE cannot accurately allocate resources or maintain service continuity across different network types
Solution Approach 1:
The patent nests compact network type identification information within the existing paging message structure. This approach maintains service continuity and resource allocation accuracy by providing necessary network type information while minimizing the increase in paging message data volume through efficient embedding rather than appending separate messages.
4Measurement precision
If the UE determines network type from paging message information, then the UE can accurately manage service capabilities, but the paging message must include additional indication information
Solution Approach 1:
The patent achieves precise network type determination by nesting indication information within the paging message. This allows the UE to accurately identify whether the paging message is associated with a public or non-public network while keeping the overall message structure integrated and manageable, rather than requiring separate complex signaling procedures.
Solution Approach 2:
The indication information serves as an intermediary that enables precise network type determination without fundamentally complicating the paging message structure. It acts as a lightweight mediator that carries the necessary identification data within the existing message framework, balancing measurement precision with structural simplicity.

AI summary
This application provides a communication method and a corresponding apparatus and system. The method includes: receiving, in a first network, a paging message that is from a first network device and that is used to page a first terminal device, where the paging message includes first information, and a network type of the first network is a first network type; and determining, based on the first information, a second network associated with the paging message that is used to page the first terminal device, where a network type of the second network is a second network type. The first network type is a non-public network and the second network type is a public network, or the first network type is a public network and the second network type is a non-public network. Cross-network paging between networks of different network types can be supported.
