Paging Triggering for Target Terminal Types
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, particularly with the introduction of IoT devices, existing paging methods trigger all terminals when only specific types of terminal devices' system information changes, leading to signaling resource waste and increased power consumption.
Innovation Solution
Implementing a method where network devices trigger paging only for target types of terminal devices by using specific paging radio network temporary identities (P-RNTI), resources, or paging early indications (PEI) associated with those devices, allowing only affected devices to receive updated system information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paging is triggered for all terminals when system information changes, then all terminals receive system information updates, but signaling overhead increases and power consumption increases
Solution Approach 1:
The patent segments terminals into different types (e.g., RedCap terminals and non-RedCap terminals) and applies different paging triggering mechanisms for each type. When system information changes affect only specific terminal types, paging is triggered only for those types rather than all terminals, thereby reducing power consumption while ensuring reliable updates for affected terminals.
Solution Approach 2:
The patent implements local quality by associating different paging radio network temporary identities (P-RNTI) with different terminal types. Specific system information changes are linked to specific terminal types, allowing the network to selectively trigger paging only for terminals that need updates, rather than universally notifying all terminals.
2Reliability
If paging is triggered for all terminals when system information changes, then all terminals receive system information updates, but signaling overhead increases
Solution Approach 1:
The patent segments the terminal population into distinct types and segments system information changes by the terminal types they affect. This segmentation enables selective paging triggering, where only terminal types affected by specific system information changes receive paging notifications, thereby reducing overall signaling overhead while maintaining reliable update delivery.
Solution Approach 2:
The patent applies local quality by creating a mapping between system information change types and specific terminal types. Each system information change is associated with the terminal types it affects, allowing the network to trigger paging locally for only those terminal types that require updates, rather than generating paging signals for all terminals.
3Loss of energy
If selective paging for target terminal types is implemented, then signaling overhead is reduced and power consumption is conserved, but device complexity increases
Solution Approach 1:
The patent segments terminals into different types and associates each type with specific paging radio network temporary identities (P-RNTI). This segmentation creates a structured framework where the network can efficiently determine which terminal types are affected by system information changes and trigger paging only for those types, managing complexity through organization rather than ad-hoc decisions.
Solution Approach 2:
The patent implements a universal paging triggering mechanism that handles multiple terminal types through a unified framework. The same paging structure and procedures are used across different terminal types, with the flexibility to selectively apply paging based on terminal type and system information change type, thereby avoiding the need for entirely separate mechanisms for each terminal type.

AI summary
A paging triggering method, performed by a network device, includes: in response to a change in system information, triggering a paging for a target type of terminal device; in which the change in the system information is associated with the target type of terminal device among at least one type of terminal device. The type of terminal device may be configured with at least one of a corresponding paging radio network temporary identity, a corresponding resource or a corresponding paging early indication.
