Terminal Paging Identifier Collision Detection and Re-allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G network co-construction scenarios, there is a risk of collision between different operators due to the use of the same 5G-S-TMSI, which can lead to incorrect routing of calls and other communication issues.
Innovation Solution
An information acquisition method and apparatus that acquires paging identifiers from GUTIs allocated by networks corresponding to multiple cards, and in cases where multiple cards share the same paging identifier, triggers the networks to re-allocate GUTIs, thereby reducing the likelihood of collisions.

Engineering Contradiction Analysis
1Loss of energy
If multiple operators share the same radio base station in 5G network co-construction, then construction costs are greatly reduced, but the risk of collision between paging identifiers increases
Solution Approach 1:
The terminal device proactively detects paging identifier collisions before they cause communication failures. By acquiring paging identifiers from GUTIs of multiple cards and comparing them in advance, the system identifies collisions early and triggers re-allocation, preventing harmful effects rather than reacting after problems occur.
Solution Approach 2:
The system implements a feedback mechanism where the terminal device continuously monitors paging identifiers of multiple cards, detects collisions, and triggers re-allocation requests to the network. This closed-loop feedback ensures that collision risks are systematically managed while maintaining cost-effective network sharing.
2Adaptability or versatility
If the same 5G-S-TMSI is used by different operators, then network resource sharing is improved, but call routing accuracy deteriorates
Solution Approach 1:
The terminal device performs preliminary detection of paging identifier collisions across multiple operator cards before communication issues arise. By comparing GUTIs and identifying duplicate paging identifiers in advance, the system prevents misrouting problems while maintaining versatile network sharing capabilities.
Solution Approach 2:
The system takes preliminary anti-action by detecting and reporting paging identifier collisions to the network, triggering re-allocation before harmful misrouting occurs. This preventive approach counteracts the potential negative effects of identifier duplication while preserving the benefits of network co-construction.
3Adaptability or versatility
If paging identifiers are not unique across multiple cards, then network co-construction flexibility is improved, but communication reliability deteriorates
Solution Approach 1:
The terminal device implements continuous feedback monitoring of paging identifiers across multiple cards, detecting collisions and triggering re-allocation requests. This feedback mechanism maintains communication reliability while preserving the flexibility of network co-construction by systematically managing identifier uniqueness.
Solution Approach 2:
The terminal device autonomously detects paging identifier collisions and triggers re-allocation requests without requiring external intervention. This self-service approach ensures communication reliability is maintained while allowing flexible network co-construction, as each terminal independently manages its own identifier conflicts.
