Multi-SIM Resource Coordination Across Different Operator Base Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-SIM terminals face data loss due to simultaneous access to multiple networks from different operators, as existing systems lack coordination between these networks, leading to overlapping resource conflicts.
Innovation Solution
A multi-SIM terminal reports auxiliary information to multiple base stations, including connection states and DRX/SPS configurations, to coordinate resources and avoid data loss by scheduling resources optimally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-SIM terminal simultaneously maintains access to multiple base stations from different operators, then the terminal can access multiple networks, but resource conflicts occur due to lack of coordination between networks
Solution Approach 1:
The patent introduces an auxiliary information reporting mechanism as an intermediary between the multi-SIM terminal and multiple base stations. The terminal reports its connection states and DRX/SPS configurations to coordinating base stations, which then use this information to coordinate resource allocation across different networks. This intermediary information exchange enables coordinated resource management without requiring direct inter-network communication infrastructure.
Solution Approach 2:
The patent implements a feedback loop where the multi-SIM terminal continuously reports its connection states and resource configuration information to the base stations. This feedback enables the base stations to adjust their resource allocation decisions based on the terminal's actual state, preventing resource conflicts and data loss while maintaining multi-network access.
2Reliability
If resource coordination is implemented between base stations, then data loss is avoided, but system complexity increases due to information exchange requirements
Solution Approach 1:
The coordination complexity is managed by using auxiliary information reports as an intermediary mechanism. Rather than implementing complex direct coordination protocols between base stations, the system uses standardized information reports from the terminal that both base stations can process independently, reducing the complexity of inter-base-station communication.
Solution Approach 2:
The terminal proactively reports its connection states and resource configurations before conflicts occur. This preliminary action allows base stations to anticipate potential resource conflicts and coordinate allocations in advance, preventing data loss without requiring complex real-time coordination mechanisms.
3Reliability
If auxiliary information is reported to multiple base stations, then resource coordination is achieved, but signaling overhead increases
Solution Approach 1:
The auxiliary information report serves multiple functions simultaneously: it provides connection state information, DRX configuration data, SPS configuration details, and resource coordination data. This multi-functionality reduces the need for separate signaling messages for each type of information, thereby reducing overall signaling overhead while achieving comprehensive resource coordination.
Solution Approach 2:
The patent combines multiple types of information (connection states, DRX configurations, SPS configurations) into a single auxiliary information report structure. By merging these information elements into one coordinated message exchange, the system reduces the number of separate signaling interactions required, thereby reducing signaling overhead while maintaining effective resource coordination.
