Multi-Card Terminal TA Sharing to Avoid Redundant Random Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-card terminal processing methods lack a uniform standard, leading to varied terminal behaviors and resource wastage due to independent random access decisions by each card, resulting in network resource and terminal power inefficiencies.
Innovation Solution
Implement a method where a multi-card terminal determines if a trigger event is a preset event and checks if a second identity recognition module has an effective Timing Advance (TA) value, controlling the first module not to initiate random access and using the second module's TA value instead, thus avoiding unnecessary random access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each identity recognition module independently initiates random access when triggered, then the terminal can ensure reliable network access for each card, but network resources are wasted and terminal power consumption increases
Solution Approach 1:
The patent merges the random access operations of multiple identity recognition modules by allowing one module to share its TA value with another module that needs it. This combines the network access efforts so that instead of each module independently performing random access, they can share the results, reducing redundant operations and power consumption while maintaining reliable access for all modules
Solution Approach 2:
The patent applies preliminary action by having the first identity recognition module obtain the TA value through random access before the second module needs it. This preliminary acquisition of the TA value allows subsequent modules to reuse it without performing their own random access, thus preventing energy-wasting redundant operations while ensuring network access reliability
2Reliability
If each identity recognition module independently initiates random access when triggered, then each card can establish independent network connection, but network resources are wasted due to redundant access attempts
Solution Approach 1:
The patent merges redundant network access operations by enabling TA value sharing between identity recognition modules. When the first module has obtained a valid TA value, the second module can reuse it instead of initiating its own random access, thereby combining network access efforts and eliminating wasteful redundant attempts while maintaining the ability for each card to establish network connections
Solution Approach 2:
The patent uses copying by allowing the second identity recognition module to copy and reuse the TA value obtained by the first module. This copying of the timing advance information enables the second module to establish network connection without performing its own random access, thus reducing network resource wastage while preserving connection independence
3Loss of energy
If TA values are shared between identity recognition modules, then resource efficiency improves, but the device complexity increases due to coordination requirements
Solution Approach 1:
The patent implements feedback mechanisms where identity recognition modules monitor each other's TA value status and trigger events. When a module detects that another module has an effective TA value and a trigger event occurs, it requests and receives the shared TA value, creating a feedback loop that automates the coordination process and reduces manual configuration complexity

AI summary
An information processing method. The method includes: determining that a trigger event of a first identity recognition module in a terminal is a preset trigger event, and determining that a second identity recognition module in the terminal has an effective timing advance (TA) value; then, controlling the first identity recognition module not to initiate random access, and determining the TA value of the second identity recognition module as the TA value of the first identity recognition module.
