Multi-SIM Capability Reporting for Accurate Network Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-SIM terminal devices face hardware limitations that degrade communication capabilities when operating in multi-standby multi-active mode, leading to inefficiencies in network scheduling and reduced throughput performance due to mismatched reported and actual communication capabilities.
Innovation Solution
A terminal device equipped with multiple SIMs reports detailed capability information for simultaneous operation, including band combinations and operating modes, to a network device, enabling accurate communication scheduling and improved efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal device operates in multi-standby multi-active mode with multiple SIMs, then the communication functionality is enhanced, but the communication capability of individual SIMs degrades due to hardware limitations
Solution Approach 1:
The patent segments the capability information by SIM card, separately reporting the communication capabilities of each SIM card individually. This allows the network device to understand the specific capabilities of each SIM card, enabling more precise scheduling and resource allocation for each SIM, thereby resolving the contradiction between multi-SIM functionality and individual SIM performance.
2Device complexity
If the terminal device reports general capability information without SIM-specific details, then the reporting complexity is reduced, but the network scheduling efficiency deteriorates due to capability mismatch
Solution Approach 1:
The patent applies local quality by providing differentiated capability information for each SIM card. Instead of a single general capability report, the terminal device reports specific capability parameters (such as bandwidth, MIMO layers, power class) for each SIM card individually. This localized detailed reporting enables the network device to perform precise scheduling for each SIM, improving network scheduling efficiency without significantly increasing overall reporting complexity.
