Dual SIM Resource Allocation for Power Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with multiple SIMs, unnecessary resource allocation occurs even when only one SIM is in use, leading to power consumption and operational issues.
Innovation Solution
An electronic device with a first SIM for data service and a second SIM irrelevant to data service, where capability information is determined and transmitted to the network to allocate resources only for the active SIM, preventing unnecessary resource allocation for the inactive SIM.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If resources are allocated to all SIMs in the electronic device, then each SIM can potentially access network services, but unnecessary power consumption occurs when only one SIM is actively used
Solution Approach 1:
The patent segments the SIM management into two distinct groups: active SIMs that require resource allocation and inactive SIMs that do not. The processor identifies which SIMs are actively used and allocates network resources only to those specific SIMs, while preventing resource allocation to inactive SIMs. This segmentation resolves the contradiction by maintaining network service accessibility for active SIMs while eliminating unnecessary power consumption from inactive SIMs.
2Adaptability or versatility
If resources are allocated to all SIMs, then all SIMs can communicate with the network, but operational performance degrades due to unnecessary resource allocation
Solution Approach 1:
The patent implements dynamic resource allocation where the system continuously monitors SIM usage status and adjusts resource allocation accordingly. When a SIM transitions from inactive to active status, resources are dynamically allocated to that SIM. This dynamic approach maintains communication capability for all SIMs that may become active while optimizing operational efficiency by allocating resources only when actually needed.
3Adaptability or versatility
If the device supports multiple SIMs with full functionality, then each SIM can support all communication functions, but unnecessary functions are activated for SIMs that don't require them
Solution Approach 1:
The patent applies local quality by configuring each SIM's capability information individually based on its actual usage requirements. Instead of uniformly enabling all communication functions for every SIM, the system determines and transmits only the necessary capability information for each active SIM to the network. This ensures that each SIM receives appropriate functional support without wasting energy on unnecessary functions.
Data Source
AI summary
An electronic device may include a first subscriber identity module (SIM), a second SIM, a communication circuit, a memory, and a processor. According to an embodiment, the memory may store instructions that when executed, cause the processor to set the first SIM to a SIM associated with a data service, and the second SIM to a SIM irrelevant to the data service to determine first capability information associated with a function supported by the electronic device in connection with the first SIM, and second capability information associated with a function supported by the electronic device in connection with the second SIM. The instructions may also cause the processor to transmit the first and second capability information to the network, and to receive allocation of a resource for wireless communication corresponding to each of the first and second SIM from the network, based on the first and the second capability information.
