Solution Overview
Problem
In wireless communication systems with terminals equipped with multiple SIM cards, existing technologies face challenges in managing communication states effectively, leading to performance degradation and resource wastage due to inadequate processing of secondary network communications, resulting in errors and inefficient resource utilization.
Innovation Solution
A method and apparatus for automatically changing the communication state of a terminal's SIM cards based on configuration information received from the network device, allowing timely switching between communication states to optimize performance, such as changing from a connected state to an idle or inactive state, thereby enabling efficient communication with multiple networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal maintains connected state for all SIM cards continuously, then communication reliability is improved, but energy consumption increases and resource utilization deteriorates
Solution Approach 1:
The terminal dynamically adjusts the communication state of SIM cards based on service requirements and network conditions. The state can switch between connected, inactive, and idle states, allowing the system to adapt between maintaining high reliability (connected state) and reducing energy consumption (idle state) according to actual needs.
Solution Approach 2:
The system changes the communication state parameter of SIM cards from a static connected state to a dynamic state that can transition between connected, inactive, and idle. This parameter change enables the terminal to optimize the balance between communication reliability and energy consumption by selecting appropriate states for different scenarios.
2Reliability
If the terminal processes all network communications equally, then communication completeness is improved, but processing efficiency deteriorates
Solution Approach 1:
The terminal segments the processing of different SIM cards into different priority levels. The first SIM card is processed with higher priority and maintained in connected state, while the second SIM card is processed with lower priority and can transition to inactive or idle states, achieving differentiated handling that improves overall processing efficiency while maintaining communication completeness.
Solution Approach 2:
Different communication states are applied to different SIM cards based on their specific requirements. The first SIM card receives premium processing (connected state) while the second SIM card receives standard processing (inactive/idle state), allowing the system to optimize processing efficiency by allocating resources according to local needs rather than treating all communications uniformly.
3Productivity
If the terminal frequently switches communication states, then resource utilization is improved, but system stability deteriorates
Solution Approach 1:
The terminal performs preliminary evaluation of service requirements and network conditions before switching communication states. By assessing whether state switching is truly necessary beforehand, the system avoids unnecessary transitions that would disrupt stability, while still enabling resource optimization through targeted state changes when appropriate.
Solution Approach 2:
The terminal implements periodic evaluation of communication state requirements rather than continuous switching. The system checks at defined intervals whether state transitions are needed, which reduces the frequency of unnecessary switches and maintains system stability while still achieving resource utilization optimization through periodic adjustments.
