Dynamic Paging Cause Indication for Multi-Card Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-card terminals in wireless communication networks face issues such as paging collisions and business interruptions due to the existing mechanisms' inability to flexibly handle multiple USIM cards, leading to inefficient use of air interface resources and poor user experience.
Innovation Solution
A paging method where a network side device dynamically determines whether to carry a paging cause in notification messages based on the number of registered USIM cards, allowing for efficient communication by adapting the paging mode to the terminal's state, thereby avoiding waste of air interface resources and ensuring high availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paging cause is always carried in notification messages for multi-card terminals, then paging collision and business interruption problems are avoided, but air interface resources are wasted due to unnecessary signaling transmission
Solution Approach 1:
The patent applies dynamics by making the paging cause indication dynamic rather than static. The network device determines whether to carry the paging cause in the notification message based on real-time conditions such as whether the terminal is in idle state and whether the terminal supports multi-USIM functionality. This dynamic adaptation resolves the contradiction by ensuring paging cause information is transmitted only when necessary, improving reliability for multi-card terminals while avoiding unnecessary resource consumption for single-card terminals or connected state scenarios.
Solution Approach 2:
The patent changes the parameter of paging message structure based on terminal characteristics. When the terminal is determined to be in idle state and supports multi-USIM, the paging cause parameter is included in the notification message. Otherwise, the paging cause parameter is omitted. This parameter change approach resolves the technical contradiction by adapting the message content to the specific terminal state, ensuring reliable paging for multi-card terminals while conserving air interface resources.
2Ease of operation
If paging cause is carried in all paging messages, then terminal can always determine appropriate paging response, but signaling processing complexity increases
Solution Approach 1:
The patent implements dynamic signaling by conditionally including the paging cause in notification messages based on terminal state and capabilities. The network device assesses whether the terminal is in idle state and whether it supports multi-USIM functionality, then dynamically decides whether to carry the paging cause. This dynamic approach simplifies signaling processing for common single-card connected scenarios while ensuring accurate paging response for multi-card idle scenarios.
Solution Approach 2:
The patent extracts the paging cause indication from the universal paging message structure and applies it selectively. Instead of always including the paging cause in all paging messages, the system extracts and includes it only when the terminal is in idle state and supports multi-USIM functionality. This extraction principle reduces signaling processing complexity for the majority of cases while maintaining terminal paging response accuracy when needed.
3Adaptability or versatility
If multi-card terminal processing is handled by individual terminal manufacturers, then various processing manners can be implemented, but terminal behaviors become inconsistent and user experience deteriorates
Solution Approach 1:
The patent applies universality by creating a standardized paging mechanism that works across all multi-card terminals regardless of manufacturer. The network device determines whether to carry the paging cause based on terminal state and capabilities, providing a universal solution that handles both single-card and multi-card scenarios. This standardized approach ensures consistent terminal behavior across different manufacturers while maintaining the flexibility to adapt to different terminal states and capabilities.

AI summary
A paging method includes: determining that a terminal has downlink data arrived, determining whether a paging cause needs to be carried in a target notification message; determining that the paging cause needs to be carried in the target notification message, and transmitting the target notification message carrying the paging cause to a second network-side device. Before sending the target notification message carrying the paging cause to the second network side device, the paging method determines a bit value corresponding to the paging cause carried in the target notification message. A paging apparatus and a storage medium using the paging method are also disclosed.
