Dual-SIM Service Data Routing via Secondary SIM Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dual-card dual-standby communication terminals suffer from low service processing flexibility and low utilization rate of network transmission resources, as communication services are limited to the card used, leading to poor communication quality and stability, especially in areas with inadequate network coverage.
Innovation Solution
A method and apparatus that transmit service data of a communication service performed by one identity identification module through a data link corresponding to a second identity identification module, enhancing flexibility and resource utilization without requiring changes to the base station or core network, and allowing for improved communication quality and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication service is implemented completely through the card related to the communication service, then the implementation is simple and straightforward, but the service processing flexibility is low and network transmission resource utilization rate is low
Solution Approach 1:
The patent segments the communication service into control plane and user plane functions. The control plane remains associated with the service card (first SIM card), while the user plane data transmission is separated and routed through the data card (second SIM card). This segmentation allows independent optimization of each plane, improving service processing flexibility without overwhelming complexity.
Solution Approach 2:
The patent introduces a gateway or network element that acts as an intermediary to bridge the control plane and user plane. This intermediary enables the data card to transmit service data while the service card maintains control functions, thereby improving resource utilization and flexibility without requiring complete reimplementation of the communication stack.
2Loss of energy
If communication service is implemented completely through the card related to the communication service, then the architecture is simple, but the network transmission resource utilization rate is low
Solution Approach 1:
The patent enables the data card (second SIM card) to serve dual purposes: its primary function for data internet access and an additional function for transmitting communication service data. This multi-functionality increases network resource utilization by allowing the data card's transmission resources to be shared for communication services, thereby reducing waste without significantly complicating the overall architecture.
3Reliability
If communication service is implemented completely through the card related to the communication service, then the card is dedicated to the service, but the communication quality and stability are poor in areas with inadequate network coverage
Solution Approach 1:
The patent implements dynamic resource allocation where the system can flexibly route communication service data through different available network resources. When the service card's network coverage is inadequate, the system dynamically utilizes the data card's network resources to maintain communication quality and stability, thereby adapting to varying network conditions without sacrificing reliability.
